1. Hydraulic oil volume and pollution
Since hydraulic oil pollution is one of the main causes of hydraulic pump failure, it is necessary to confirm the pollution status of hydraulic oil in time. (Change hydraulic oil in 600 hours and filter element in 100 hours).
The lack of hydraulic oil will cause cavitation, which may cause hydraulic pump failure, breaker piston cylinder strain, etc.; suggestion: check the oil level before use every day.
2. Replace the oil seal in time
The oil seal is a vulnerable part. It is recommended that the breaker work for about 600-800 hours and replace the breaker oil seal; when the oil seal leaks, the oil seal must be stopped immediately, and the oil seal must be replaced. Otherwise, side dust will easily enter the hydraulic system, damage the hydraulic system, and damage the hydraulic pump.
3, keep the pipeline clean
When installing the breaker pipeline, it must be thoroughly cleaned and the inlet and return oil lines must be cyclically connected; when replacing the bucket, the breaker pipeline must be blocked to keep the pipeline clean.
Sundries such as sand can easily damage the hydraulic pump after entering the hydraulic system.
4. Use high-quality breaker (with accumulator)
Inferior breakers are prone to problems due to design, manufacturing, inspection and other links, and the failure rate is high during use, which is more likely to cause damage to the excavator.
5, suitable engine speed (medium throttle)
Because the breaking hammer has low requirements for working pressure and flow (such as a 20-ton excavator, working pressure 160-180KG, flow 140-180L/MIN), it can work at a medium throttle; if it works at a high throttle, it will not increase the blow It will cause the hydraulic oil to heat up abnormally, and will cause great damage to the hydraulic system.
