How to protect the hydraulic pump of the breaker?


1. Use high-quality breakers with accumulators. Poor-quality breakers are prone to problems due to design, manufacturing, inspection and other links, and the failure rate in use is high, which is more likely to cause damage to the excavator.
2. The hydraulic system should be preheated before the breaker is used. When the breaker is parked, the hydraulic oil in the upper part will flow to the lower part. After the oil film is formed, use the medium throttle to operate, which can protect the hydraulic system of the excavator.
3. Air hitting will not only cause the oil temperature to rise, but also cause abnormal vibrations to cause impurities to enter the rigid body of the breaker, so air hitting is strictly prohibited.
4. Be sure to add lubricating grease when the steel is brazing straight, and refill it every 2 hours. If the lubricating oil is supplemented in the suspended state of the steel rod, 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.
