How to use hydraulic breaking hammer to protect hydraulic pump water mountain breaking hammer
We should use good hydraulic breaking hammers. Poor hydraulic breaking hammers are prone to problems due to design, manufacturing, inspection and other links. The failure rate in use is high, which is more likely to cause damage to the excavator. At appropriate engine speed, the hydraulic crushing hammer has low requirements for working pressure and flow, and can work with medium throttle; If the high throttle works, it will not only not improve the strike force, but also cause abnormal temperature rise of hydraulic oil and great damage to the hydraulic system.
For the correct position, frequency and quantity of grease, be sure to add lubricating grease when the steel drill is pressed straight, and fill it every 2 hours. If lubricating grease is added when the steel drill is suspended, the grease will enter the striking chamber. During striking, abnormal high pressure oil will be generated in the striking chamber, and the oil will enter the hydraulic system and damage the hydraulic pump. For the breaking hammer, we should replace the oil seal in time. The oil seal is a vulnerable part. It is recommended to replace the oil seal of the breaking hammer once after the breaking hammer works for about 600-800 hours; When the oil seal leaks oil, stop working immediately and replace the oil seal. No side dust is easy to enter the hydraulic system and damage the hydraulic system and hydraulic pump;
Since hydraulic oil pollution is one of the main causes of hydraulic pump failure, the pollution status of hydraulic oil should be confirmed in time. Generally, replace the hydraulic oil in 600 hours and replace the core in 100 hours. The lack of hydraulic oil will produce cavitation phenomenon, resulting in hydraulic pump failure, hydraulic crushing hammer piston cylinder strain, etc; So we check the oil level before use every day. Keep the pipeline clean. When installing the hydraulic crushing hammer pipeline, it shall be thoroughly cleaned, and the inlet and return oil circuits shall be connected circularly; When replacing the bucket, block the hydraulic crushing hammer pipeline and keep the pipeline clean; Sand and other sundries are easy to hurt the hydraulic pump after entering the hydraulic system. The hydraulic breaking hammer used for demolition is more frequently damaged than the hydraulic breaking hammer used in the mine. Because the dust is easy to enter the hydraulic breaking hammer cylinder along the steel drill, resulting in the pollution and rapid aging of hydraulic oil, it is recommended to install an oil return filter element in the oil return circuit.
The hydraulic system of the hydraulic breaking hammer shall be preheated before use. Since the hydraulic oil in the upper part will flow to the lower part when the hydraulic breaking hammer is parked, it is recommended to operate with a small throttle at the beginning of use every day. After the oil film of the piston cylinder block of the breaking hammer is formed, use a medium throttle to operate, which can protect the hydraulic system of the excavator. When storing the hydraulic breaking hammer for a long time, the steel drill should be removed first, the nitrogen in the upper cylinder should be released, and the piston should be pushed to the end to avoid rusting or galling of the exposed part of the piston and damaging the main pump of the main engine. Empty beating will not only cause the rise of oil temperature, but also produce abnormal vibration, resulting in impurities entering the rigid body of hydraulic crushing hammer, so empty beating is strictly prohibited.
