    How to protect the hydraulic pump when the excavator is equipped with a breaker?- Part one

    Because the breaker is a reciprocating and fast impact motion, the return speed of oil is fast and the relative pulse is relatively large, which causes the aging speed of the hydraulic oil to accelerate. Therefore, it is necessary to maintain the excavator and use it properly, which can effective...
