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.

What are the effects of oil pressure on the breaker

The breaker is an auxiliary equipment for many construction machinery. Now many projects have more and more demands for modern machinery and equipment. The breaker needs suitable oil pressure to work normally. Many friends must know this, but the oil pressure is in the end. How much should be appropriate, and what are the effects of oil pressure on the breaker? Oil pressure measurement According to the design pressure parameters, install an oil pressure gauge greater than the design pressure in the corresponding position. For the new excavator with a breaker, it is generally between 200-220, and for the old excavator, it is generally above 230 . If the oil pressure is too high in actual use, the load on the breaker may also increase, and the oil temperature will also rise. If the oil temperature is too high, the transmission pressure of the hydraulic oil will be insufficient, resulting in equipment failure. If it does not work properly, if it is not solved for a long time, it will damage the breaker accumulator, resulting in air leakage and oil leakage. Once we find that the oil temperature rises too high during use, we should consider replacing the oil cooler of the equipment, or install an auxiliary cooler to achieve our purpose. It is also very important to clean the oil filter in time. Pivotal.
