What improper operations can cause shock damage to the breaker?

The breaker hammer will inevitably produce consumption during the crushing operation, which mainly includes wear and tear caused by the internal operation of the machine and the consumption caused by applying force. However, it should be noted that when the breaker hammer is applying force to the outside, it will be interfered by external force reaction. This kind of The recoil force will be purposefully considered in the design, and if the control is poor, the striking ability will not be fully activated; at the same time, the impact force of the breaker hammer will rebound to the breaker body, guard plate and engineering The operating arm of the machine itself, etc., causing damage to the above locations.

What are the improper operations that can cause damage to the breaker due to the shock back force?

The breaker strikes dry when there is no target. When the rock or target has been crushed, please stop the impact action of the breaker immediately. Continuous impact without target will only cause the screws of the precursor and main body to become loose and damaged. What's more, it may damage the engineering machinery.

Improper engine speed selection. Carry out crushing operations at an appropriate engine speed. Usually, improperly increasing the engine speed beyond the speed required for the operation fails to enhance the compressive strength of the impact force; on the contrary, it will cause the hydraulic oil to The temperature rises rapidly, causing the lubrication ability and operating ability to decrease, which is not conducive to the risk of piston and valve.

The breaker hammer falls on a hard rock. When the breaker hammer is dropped quickly and hits hard on the surface of the hard rock, excessive impact damage will be caused to the breaker hammer or engineering machinery, causing damage to parts.

Work when the hydraulic cylinder is fully extended or fully retracted. If you perform a blow operation when the hydraulic cylinder is fully extended or fully retracted, the shock vibration will rebound to the hydraulic cylinder body and cause serious damage to the construction machinery.
