How can a hydraulic drill use emulsified hydraulic oil?

The main reason for the emulsification of hydraulic oil in hydraulic drilling rig is that water is mixed with hydraulic oil. When water enters the pumping station and contacts with hydraulic oil, due to the interaction between water molecules, water is suspended in hydraulic oil as a large body of water, and then through the high-pressure action of the hydraulic system, the water mass is decomposed into water molecules evenly dispersed around the hydraulic oil molecules, and after a certain period of oxidation and deterioration, The hydraulic oil will turn white and emulsify.

The main reason for the emulsification of hydraulic oil in hydraulic drilling rig is that water is mixed with hydraulic oil. When water enters the pumping station and contacts with hydraulic oil, due to the interaction between water molecules, water is suspended in hydraulic oil as a large body of water, and then through the high-pressure action of the hydraulic system, the water mass is decomposed into water molecules evenly dispersed around the hydraulic oil molecules, after a certain period of oxidation and deterioration. The hydraulic oil will turn white and emulsify.

02. The harm of emulsified hydraulic oil to hydraulic drilling rig:

In response to the customer's feedback on a hydraulic column drilling rig that was unable to drill, the oil tank was tested with emulsified hydraulic oil filled by the customer. During the test, the pressure and propulsion force of the propulsion cylinder did not rise during the repeated pushing and pulling process, and the torque of the rotary device was 170N.m when the parameter of the comprehensive torque test bench was 150r/min.

After thoroughly cleaning the pipeline, the pure HM46# anti-wear hydraulic oil was re-added for test. After repeated pushing and pulling two effective strokes, the pushing and pulling speed of the hydraulic column drilling rig was significantly increased, and the pressure and jacking force of the auxiliary pump reached the rated value. When the test parameter of the gyroscope on the comprehensive torque test bench was 260r/min, the torque was 423N.m.

To sum up, the use of emulsified hydraulic oil will cause the failure of the hydraulic drilling system and affect the normal operation of the equipment. When using the hydraulic column drill, be sure to fill the pure anti-wear hydraulic oil that meets the label requirements as required, and check the oil regularly.

If it is found in the process of use that the hydraulic components of the hydraulic drilling rig are weak, there are obvious bubble sounds in the oil tank, and the oil temperature is overheating, it is recommended to open the tank lid to check whether the oil has been white, if it is white emulsified, it is recommended to clean the pipeline immediately and replace the pure hydraulic oil. You can't use emulsified hydraulic oil anymore, "leukemia" will really destroy the hydraulic drill!
