AI Technical Summary
The existing impact equipment has a complex reversing mechanism, slow reversing speed, and the braking effect of the reversing valve decreases with use time. In particular, the throttling method of low-power equipment has limited effect and high cost.
A reversing mechanism equipped with a resistance valve is adopted. Through the combination of piston device and reversing valve, the resistance valve applies rated resistance to the return oil during the piston return stroke, so as to realize the stable alternating movement of the reversing valve and adjust the resistance to meet the needs of equipment with different power.
It simplifies the equipment debugging process, has a wide range of applications, provides stable and reliable resistance adjustment, extends the life of components, and reduces the probability of cavitation.
