What are the cold resistance measures for hydraulic pile drivers?

1. Do a good job in preheating the hydraulic pile driver

For the engine, when starting at low temperatures, the high viscosity of the engine oil can cause a short-term shortage of lubricating oil and prevent it from reaching all lubrication points. If the engine runs at high speeds, it can cause increased wear on the crankshaft, camshaft, rocker arm shaft, etc., and serious accidents such as cylinder pulling and tile burning. So, after starting the engine, it should idle for a period of time and then increase the load when the water temperature rises. The same goes for hydraulic system preheating. If the temperature is too low and the viscosity of the hydraulic oil is high, it will be difficult to absorb oil, resulting in insufficient pump oil volume and affecting the force and sensitivity of the actuator components.

2. Choose the appropriate oil for the hydraulic pile driver

In winter, it is important to choose fuel and lubricants based on the local low temperature. Oil also needs to be replaced with different winter oils according to different types of equipment to reduce starting and running resistance and ensure lubrication. Due to the low temperature in winter, the viscosity of hydraulic oil increases, and the negative pressure of hydraulic pump suction increases, resulting in insufficient oil supply and affecting the accuracy and sensitivity of actuator operation. Therefore, it is also necessary to choose the specified type of hydraulic oil.

3. Strengthen equipment inspection and maintenance work

As the temperature drops, sealing components such as equipment cylinders and hydraulic pipe joints will crack and shrink, causing poor sealing and leakage. Various transmission connections and bolts will also be affected by low temperatures, resulting in a decrease in strength and stiffness, such as water seal cover plate leakage on one side of the engine, loose transmission shaft screws, and loose pin connections. So it is necessary to strengthen inspections, promptly identify problems, eliminate small hidden dangers, and avoid causing major malfunctions.

The above are several common cold prevention measures for hydraulic pile drivers. Do you understand? Everyone can use the above method to keep the pile driver warm. In addition, strict inspections should be carried out before and after the start and end of each day to avoid human accidents, ensure the normal operation of equipment, and ensure the normal progress of winter construction.
