How to protect the hydraulic pump of the crushing hammer?

The working form of a crushing hammer is a rapid reciprocating impact movement within the hydraulic system, and the oil return speed of such large machinery is fast and relatively large, which will also accelerate the aging speed of the hydraulic pump. Therefore, it is necessary to properly maintain the crushing hammer and hydraulic pump series components. Let's take a look at our commonly used methods:

1. Use high-quality crushing hammers with energy accumulators. Poor quality crushing hammers are prone to problems in design, manufacturing, inspection, and other aspects, resulting in a high failure rate during use and more likely to cause damage to the excavator.

2. Before use, the hydraulic system of the crushing hammer should be preheated. When the hammer is parked, the hydraulic oil from the upper part will flow to the lower part. It is recommended to operate with a small throttle every day at the beginning of use. After the oil film on the piston body of the crushing hammer forms, operate with a medium throttle to protect the excavator hydraulic system.

3. Air striking not only causes an increase in oil temperature, but also generates abnormal vibrations that can cause impurities to enter the rigid body of the crushing hammer, so it is strictly prohibited to air strike.

4. Be sure to replenish lubricating grease in the straight state of the steel drill, and add it every 2 hours. If lubricating grease is added while the steel drill is suspended, the grease will enter the striking chamber, and abnormal high pressure oil will be generated in the striking chamber during striking, which will enter the hydraulic system and damage the hydraulic pump.

5. When storing the crushing hammer for a long time, the steel drill should be removed first, and the nitrogen in the upper cylinder should be discharged to push the piston to the end, to avoid rusting or galling of the exposed part of the piston and damage to the main engine pump.

6. Due to hydraulic oil contamination being one of the main causes of hydraulic pump failure, it is necessary to promptly confirm the contamination status of the hydraulic oil. Lack of hydraulic oil can cause cavitation, which can cause hydraulic pump failure, damage to the piston body of the hammer, etc. Check the oil level before use every day.
