Hydraulic pile drivers are more commonly used equipment in highway engineering, and they are also one of the equipment required by various road construction companies and engineering teams of all sizes.If you operate in the cold winter, you need some cold-proof measures to ensure the normal operation of the equipment. Then, what are the cold-proof measures for hydraulic pile drivers?Let's find out together：

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

For engines, when starting at low temperatures, due to the high viscosity of the oil, the lubricating oil will be insufficient in a short period of time and cannot be distributed throughout the lubrication points. At this time, if the engine is running at high speed, the wear of the crankshaft, camshaft and rocker shaft will be aggravated, and the heavy will cause serious accidents such as pulling cylinders and burning tiles.Therefore, the engine should be idled for a period of time after starting, and the load will be added after the water temperature rises.The same is true for the preheating of the hydraulic system. The temperature is too low and the viscosity of the hydraulic oil is large, which makes it difficult to absorb oil, and the amount of oil pumped is insufficient, which affects the strength and sensitivity of the action of the actuator.

2. Choose a good oil for the hydraulic pile driver

In winter, fuel and lubricating oil should be selected according to the low local temperature.The engine oil also needs to be replaced with different winter oils according to different equipment types to reduce start-up and operating resistance and ensure lubrication.Due to the low temperature in winter, the viscosity of the hydraulic oil increases, and the negative pressure of the hydraulic pump increases, resulting in insufficient oil supply, which affects the operating accuracy and sensitivity of the actuator, so the specified type of hydraulic oil must also be selected.

3. Strengthen equipment inspection and maintenance work

When the temperature drops, the seals of the equipment cylinders, hydraulic pipe joints, etc. will crack and shrink, causing the seals to be lax and leaking, and the transmission connectors and bolts will also be affected by the low temperature, causing the strength and stiffness to decrease, such as leakage of the water seal on one side of the engine, loosening of the drive shaft screws, pin connection falling off, etc.Therefore, it is necessary to strengthen inspections, find problems in time, eliminate small hidden dangers, and avoid causing major failures.

The above are several common cold-proof measures for hydraulic pile drivers. Do you understand?You can follow the above method to protect the pile driver from the cold.In addition, strict inspections should be carried out before and after the start of work every day to avoid man-made accidents, ensure the normal operation of equipment, and ensure the normal progress of winter construction.
