The hydraulic oil is harmful to water, what methods can remove the water?
2021 / 09 / 06
The hydraulic oil is harmful to water, what methods can remove the water? If water is accidentally mixed into hydraulic fluid, it will cause the following hazards 1. After a certain amount of water is mixed into the oil, the hydraulic oil will emulsify and become cloudy. If the anti-emulsification ability of the hydraulic oil itself is poor, after a period of rest, the water cannot be separated from the oil, making the oil always in a white turbid state. This turbid emulsified oil enters the hydraulic system, which not only makes the components of the hydraulic valve rust, but also reduces its lubrication performance, which intensifies the wear of parts and reduces the efficiency of the system. 2. After the iron-based metal in the hydraulic system rusts, the peeled rust flows in the hydraulic system pipes and hydraulic components, spreads and spreads, which will cause the entire system to rust and produce more peeling rust and oxides. 3. Water will also interact with certain additives in the oil to produce contaminants such as precipitation and colloids, accelerating the deterioration of the oil. 4. The effect of sulfur and chlorine in water and oil produces sulfuric acid and hydrochloric acid, which intensifies the abrasion and wear of the components, accelerates the oxidative deterioration of the oil, and even produces a lot of sludge. 5. These water pollutants and oxidation products immediately become catalysts for further oxidation, eventually causing blockage or jamming of
Can metal cutting fluid be used to process glass?
2021 / 08 / 31
Can metal cutting fluid be used to process glass? Today, when optical glass and mobile phone glass are widely used, glass processing fluids have also become popular. Take the product of glass cutting fluid for example. There were many cutting fluid companies that used metalworking fluids before, but none of them specialized in glass processing fluids, so they would encounter various types of cutting fluids when using them. problem. Today I will discuss with you the difference between metal cutting fluid and glass cutting fluid. First, let`s take a look at the main ingredients and uses of the two cutting fluid products. The main components and functions of metal cutting fluid. 1. Metal cutting fluids are generally divided into A. Water-soluble cutting fluid B. Emulsion C. Cutting oil The formula of each cutting fluid product is extremely complex, a
What is the difference between hydraulic support antifreeze and car antifreeze?
2021 / 08 / 23
Antifreeze for hydraulic support It is used to prevent freezing of hydraulic equipment such as hydraulic supports, external injection single hydraulic props and other hydraulic equipment in severe cold seasons, such as ground storage, lifting well maintenance, and factory transportation. ▼Identification method of antifreeze liquid for hydraulic support: 1. Price: As far as the price is concerned, the reference freezing point -25℃ liquid price is below 5 yuan/kg, it will basically not be the real product; 2. Smell, all kinds of pungent and unpleasant odors must be fakes, the real ones do not have much odor; 3. Hand feeling: non-lubricating and volatile (note: it is strictly forbidden to taste it with your mouth! Antifreeze additives contain carcinogens) is easy to open fake antifreeze added with low boiling point alcohol; the hydraulic support antifreeze packaging barrel has a white mouth If the solid appears, it is heavier to lift by hand, feels very astringent, and has no special smell. It is a fake antifreeze processed with industrial salt or brine;
Can the oily anti-rust oil that has been watered in still be used?
2021 / 08 / 16
Recently, a customer was unable to process the product because a tank of rust-preventing oil entered water. Calling us in a hurry, I solved it for him immediately and sent a new anti-rust oil. So many friends asked if the previous oil should be left out like this? Isn't that wasteful? How can the water in the anti-rust oil be removed? The editor will tell you about it. In the actual production process, if water enters the oil, what should the staff do at this time? There are three forms of water pollution in the lubrication system: dissolved water, emulsified water, and free water. Dissolved water refers to the water dissolved in the oil, which is invisible to the naked eye. When the water content mixed in the oil is higher than the soluble limit of the oil, the oil is saturated, and tiny water droplets are suspended in the oil to form emulsified water. From the appearance point of view, the transparency of the oil is reduced, turbid and white, and the oil is emulsified. Free water refers to the moisture behind the oil-water layer. Since oil is usually lighter than water, free water is in the lower layer. There are five basic methods commonly used to determine the water content in lubricating oil, including methods that can be tested on-site by themselves, and professional testing in the laboratory.
How does copper wire drawing oil prevent oxidation and blackening?
2021 / 08 / 07
In the wire drawing process of my country's wire and cable industry, copper material and enameled wire industry, oxidation, discoloration and blackening are common, and it is more serious in spring and summer. With the popularization of existing high-speed machines, the drawing speed has been greatly improved, and the contradiction has become more and more prominent. For these problems and their relationships, I focus on the analysis of the temperature caused by the copper wire drawing process that affects oxidation lubrication and other issues: because the wire temperature and the friction between the wire and the mold directly affect the lubrication effect during the drawing process, the following Analyze the aspects: one is the fat content of the lubricating oil; the second is the stretching speed and the temperature of use; the third is the stretching force; the fourth is how to prevent oxidation and blackening. 1. Fat mass The grease content of the drawing oil produced by almost every manufacturer is different. The grease content, viscosity and use temperature of the drawing oil are the main reasons that affect the lubricating effect. Let's analyze them separately: The so-called fat mass can be simply understood as the thickness of the oil film formed in the deformation zone during
How to control the filling amount of motor bearing grease?
2021 / 07 / 26
Lubrication has always been a topic of constant discussion among motor manufacturers and users. Through a large amount of test data, it can be found that too much or too little grease is not conducive to the lubrication of bearings. Excessive filling of grease will cause a large amount of grease to accumulate in the bearing cap and the inner cavity of the bearing, which will increase friction, increase the temperature, and seriously affect the heat dissipation of the bearing system. Similarly, if the filling amount is insufficient, the oil film of the grease will be repaired. If the performance is not strong, the bearing will run under poor lubrication and burn out due to insufficient lubrication. Therefore, it is important to determine the proper amount of grease in the bearing. Generally, the bearing should not be filled with grease, so that it can be installed to 1/2 to 3/4 of the total space of the bearing cavity. Horizontal bearings fill 2/3 to 3/4 of the inner cavity space; vertically mounted bearings fill the upper end of the inner cavity space by 1/2 of the inner cavity space, and lower end bearings are filled by 3/4 of the inner cavity space. In an environment that is prone to pollution, for low-speed or medium-speed bearings, the entire space in the bearing cover should be filled; for high-speed bearings, the bearings should be placed in high-quality lubricating oi
What is the difference between 46# and 68# anti-wear hydraulic oil? How to choose?
2021 / 07 / 20
Anti-wear hydraulic oil (HM) is mainly used in hydraulic systems for heavy-duty, medium-pressure, high-pressure vane pumps, plunger pumps and gear pumps. It is used for hydraulic systems of medium-voltage and high-pressure engineering machinery, imported equipment and vehicles, such as hydraulic systems such as CNC machine tools, tunnel boring machines, crawler cranes, coal shearers, etc. Today we take a look at the difference in performance between 46# anti-wear hydraulic oil and 68# anti-wear hydraulic oil: 1) Kinematic viscosity is different At 40°C in the laboratory, the kinematic viscosities of the two types of hydraulic oil are different. The viscosity of No. 46 anti-wear hydraulic oil is 46±5, and the viscosity of No. 68 anti-wear hydraulic oil is 68±5. It is very popular that the viscosity of No. 46 anti-wear hydraulic oil is thinner than that of No. 68 anti-wear hydraulic oil. If it is winter, the viscosity will be thinner to facilitate circulation; in summer, the temperature is high, and the viscosity is higher. 2) Different pour point In actual use, there is still a big difference between the pour point of No. 46 anti-wear hydraulic oil and No. 68 anti-wear hydraulic oil. For example, in the central region, the temperature in winter is around 0℃ for a long time. If you use No. 68 in summer Anti-wear hydraulic oil, cold start performance of your equipment may be worse in winte
Can the vacuum pump oil be replaced by other oil?
2021 / 07 / 10
A vacuum pump is a device that uses a certain method to pump air to a container to obtain a vacuum. It is a device that improves, generates and maintains a vacuum in a closed space. The vacuum pump oil has very good oxidation stability, is not easy to deteriorate, can reduce the formation of grease, and can be used for a long time without replacement. In addition, the vacuum pump oil has excellent corrosion resistance and can make the vacuum pump less prone to rust, because the special properties of this oil form a film on the surface of the vacuum pump to fully protect the vacuum pump, and due to the special nature of the oil, the vacuum pump oil can easily The water is separated to achieve the purpose of vacuum. The use of vacuum pump oil can also greatly increase the service life of the pump and save the cost of use. This is the essential reason why vacuum pumps need special vacuum pump oil. In the vacuum pump, the vacuum pump oil is not only used as the medium to obtain the vacuum, but also plays the role of lubricating, cooling and sealing the mechanical friction points. The main performance requirements of vacuum pump oil include the following: 1. Very low vapor pressure 2. Proper viscosity and good viscosity-temperature characteristics 3. Good thermal oxidation stability 4. Good corrosion resistance and demulsibility 5. Higher flash point 6. Lower ultimate pressure
What should I do if the oil-based cutting fluid is mixed with water?
2021 / 07 / 04
Oil-based cutting fluid is not easy to deteriorate during use. It is a long-term use and easy-to-manage cutting fluid. Generally, it only needs to be refilled regularly to maintain sufficient circulating oil. The so-called easy management is only relative to water-based cutting fluids. In order to maintain the performance of oil-based cutting fluid for a long time, strengthening management is also necessary. When injecting new cutting fluid, the oil tank must be cleaned in advance to remove chips, sludge, sludge, etc. If the new cutting fluid is mixed with deteriorated cutting fluid, oil, etc., it will accelerate the deterioration of the new fluid. When changing to another cutting fluid during use, check the compatibility and performance changes of the two cutting fluids in advance. If incompatibility or performance decreases after mixing, the former cutting fluid must be removed beforehand. Change to the latter cutting fluid. 1. The following issues must be paid attention to in the use and management of oil-based cutting fluid (1) The lubricity and corrosion inhibition are reduced due to the mixing of water. (2) The performance is reduced due to the reduction of active ingredients due to the mixing

There are all kinds of high-temperature chain oils on the market, both expensive and cheap. Why are the prices so different? Let's tell you: Reasons for the big difference in the price of high-temperature chain oil: 1) Different types of high-temperature chain oil: the price of mineral type is much cheaper than synthetic type; 2) Different raw materials: imported raw materials will be much more expensive than domestic ones, and the price of correspondingly produced high-temperature chain oil will vary greatly 3) The types of suppliers are different: the price of factory direct sales will be much lower than the price supplied by agents, and factory direct sales will eliminate intermediate links, and the price will be reduced accordingly; 4) Brand effect: The price of oil products of well-known brands is slightly higher than that of local niche brands; 5) The difference between national standard oil and non-standard oil: the price of nat
How to choose and apply heat transfer oil?
2021 / 06 / 26
The heat transfer oil is partially added and replaced gradually during use, and the service life is generally relatively long. According to the German heating system safety technical standard (DN4754), the qualified heat transfer oil should be used at the highest temperature for at least one year. Selection of heat transfer oil Select the product according to the use temperature limit The so-called use temperature limit of the heat transfer oil refers to the upper and lower temperature limits that are directly related to the efficient and safe operation of the heat transfer system. The evaporability and safety of the heat transfer oil flash point opening meets the standard index requirements, the initial boiling point is not lower than its maximum use temperature, the distillation range is relatively narrow, and the spontaneous ignition point is high. The refined depth of the heat transfer oil is a light yellow transparent liquid, with good storage stability, and does not change color or precipitate after exposure to light. The residual carbon is not more than 0.1%, and the sulfur content is not more than 0.2%. The low-temperature fluidity of the heat transfer oil is based on the user's area and the ambient temperature of the equipment, and the appropriate low-temperature performance is selected. The heat transfer performance of heat transfer oil has lower viscosity, higher density, higher specific heat capacity and thermal
What is the difference between anti-rust fluid and anti-rust oil?
2021 / 06 / 20
When we talk about products used for surface anti-rust, they mainly refer to anti-rust fluid, anti-rust oil and anti-rust grease. It is obvious from the appearance that the anti-rust grease is a solid anti-rust product, while the anti-rust oil and anti-rust fluid are liquid. So what are the characteristics of each of the liquids and the anti-rust effect is the same? 1. Anti-rust fluid Anti-rust fluid refers to an aqueous solution containing a certain amount of water-soluble corrosion inhibitor. It is often used for rust prevention between processes and is easy to remove without affecting the next process. For example, the rust prevention of workpieces during machining processes such as turning, cutting, grinding, etc., is inseparable from rust prevention water. Anti-rust water has the characteristics of convenient use, safety and economy, but the anti-rust period is generally short. If it is sealed for a long time, it needs to be replaced regularly and refilled with new liquid. How to use anti-rust fluid? There are full immersion method, spray method, cold coating method and hot coating method. Small parts are suitable for the full immer
How to solve common problems such as multi-emulsification of gear oil foam?
2021 / 06 / 15
The role of gear oil in industrial production is very large, and its main role is to reduce the obstacles when gears are running. However, there is a problem that plagues everyone when using gear oil, that is, the foam problem. So do you know why the use of gear oil for production will produce foam? Foam problem: Gear oil is prone to foam during use. Gear oils contain 5-10 micrograms/g of anti-foaming agents. Poor dispersion of anti-foaming agents or poor storage stability, water in the fuel tank, and sludge in the fuel tank will all cause the production of industrial gear oil foam. The oil level of the gear oil tank is not high enough. The large amount of air entering during operation will also increase the production of industrial gear oil foam, so that the original foam has not disappeared, and a large amount of new foam is produced; sometimes too much foam is generated The inlet popped out and overflowed. The hazards of foam: Excessive foam accelerates the oxidation of gear oil and causes insufficient lubrication of gears. If foam occurs, you can add gear oil of the same type and brand to appropriately increase the oil level of the gear oil tank, reduce air entry, strengthen the sedimentation and
What is Shear Stability Index (SSI)?
2021 / 06 / 01
Shear stability index (SSI) is an important performance of viscosity index improver. It directly affects the stability of multi-grade engine oil viscosity. Shear stability is related to the relative molecular mass of the viscosity index improver, the relative molecular mass fraction and the polymer structure, but is mainly determined by the relative molecular mass. The greater the relative molecular mass of the same type of viscosity index improver, the worse the shear stability. There are several ways to improve the shear stability: One is to reduce the relative molecular mass of the viscosity index improver and narrow the relative molecular mass distribution, and the other is to improve the stability of the polymer structure so that the polymer maintains a higher thickening ability. At the same time, it has good shear stability. Shear stability test: During the use of the oil with viscosity index improver, due to the effect of mechanical shear, the high molecular polymer in the oil is sheared, which reduces the viscosity of the oil and affects normal lubrication. Therefore, shear stability is a special physical and chemical property that must be tested for this type of oil. There are many methods for measuring shear stability, including ultrasonic testing, nozzle shearing, Wicks pump shearing, and FZG gear shearing. These methods are ultimately used to determine the viscosity drop rate of oil. Shear stability measure: Add the viscosity index improver to the base oil to prepare 15W/40 CF-4 oil. Suppose the shear temperature is t, and V0 and V are the viscosity of the oil before and a
The classification of gear oil and the meaning of specifications and models.
2021 / 05 / 22
Gear oil is divided into two categories: One is vehicle gear oil: including manual transmission gear oil and rear axle gear oil; The other is industrial gear oil: among them, industrial gear oil are divided into industrial closed gear oils, worm gear oils, and industrial open gear oils. Classification by quality: Referring to the performance classification of gear oils proposed by the American API (American Petroleum Institute), gear oils in my country are divided into ordinary vehicle gear oils (GL-3), medium-duty vehicle gear oils (GL-4), and heavy-duty vehicle gear oils ( GL-5) grade three, the quality is equivalent to GC-3, GC-4, GC-5 grade oil of the United States. (Generally, the good order of oil quality and performance is GL-3 to GL-5). Classification by viscosity: The viscosity classification of my country's vehicle gear oil adopts the American Society of Automotive Engineers (SAE) viscosity classification method, which is divided into seven viscosity grades: 70W, 75W, 80W, 85W, 90, 1

How much do you know about the "oil film strength" and "oil film thickness" of engine oil?
2021 / 04 / 13
How much do you know about the "oil film strength" and "oil film thickness" of engine oil? Regarding the strength of the oil film, I read the information and it is defined as follows: The oil film has the ability to resist pressure without breaking, and to maintain sufficient oil film thickness to prevent direct contact with the friction surface. What is oil film strength? In terms of definition, the difference between oil film strength and oil film thickness is well stated. A parameter indicating the strength of the oil film is called "HTHS". This parameter is the apparent viscosity of the oil through the capillary viscosity test at 150°C, which is the dynamic viscosity. Because HTHS reflects the adhesion ability of the lubricating oil between the piston and the cylinder and between the shaft and the bearing bush, it is related to the oiliness agent or polar agent added to the lubricating oil. Many people call it "oil film strength". It is understood that the strength of the oil film is vivid and accurate. What is the oil film thickness? The oil film refers to the protective film formed by the oil in the engine, which will exist at all times. Since there is a film, there will be thickness. How is the thickness of the oil film measured? It can be simply understood as: high viscosity oil means thick oil film, thin oil means thin oil film. Why do you say that? Let's first look at the definition of viscosity. Viscosity is the internal resistance of the fluid, so the viscosity of lubricating oil is usually the thi
The difference between hydraulic oil and anti-wear hydraulic oil, can it be replaced?
2021 / 04 / 07
Hydraulic oil and anti-wear hydraulic oil look very similar, which has caused many people to be confused between the two. Today I will tell you the difference between hydraulic oil and anti-wear hydraulic oil. The difference between hydraulic oil and anti-wear hydraulic oil 1. Different composition: Hydraulic oil = refined base oil + anti-oxidant and anti-rust additives. Anti-wear hydraulic oil = hydraulic oil + anti-wear additives, etc., with better lubrication effect. 2. Different applications: Hydraulic oil: In addition to being used in the medium and high pressure hydraulic systems of various hydraulic pumps, it can also provide lubrication for medium-duty industrial gears. Anti-wear hydraulic oil: more emphasis is placed on the hydraulic system of heavy-duty, medium-pressure, high-pressure vane pumps, plunger pumps and gear pumps. 3. The use time is different: Hydraulic oil: There are many types, and the use time of each type is different. Anti-wear hydraulic oil: The use time of high-
Is there a difference between gear oil and automatic transmission fluid (ATF)?
2021 / 03 / 25
This is a problem that many car owners are confused, is there a difference between gear oil and automatic transmission fluid (ATF)? The simplest explanation is that gear oil is usually used in manual transmissions, while transmission oil is generally used in automatic transmissions. However, as with car lubricants, there are exceptions to this rule. In order to fully understand the differences between them, we must first study the main differences between gearboxes and automatic transmissions. Manual Gearbox The manual gear is based on a two gear shaft system. After the user inputs through the clutch and the shift lever, the gears will mesh together. This means that when two moving objects are gathered together, the manual gearbox will generate a lot of heat and friction. Therefore, the gear oil must be able to make these gear transitions as smooth as possible to prevent damage to them when the components are moved. Gear oil should have good anti-wear, load-resistant performance and suitable viscosity. In addition, it should also have good thermal oxidation stability, anti-foaming properties, water separation properties and anti-rust properties.
