HammerIt is a main special tool for excavators, which can crush stones and rock formations more reasonably and promote the progress of the operation. It is generally used for digging mountains, crushing ground, paving roads, demolishing bridges, mining crushing stones and other working conditions. It is mainly composed of cylinder block, piston rod, drill rod, hydraulic reversing valve, accumulator, sealing ring components and other parts. Push the cylinder rod upwards to compress the nitrogen chamber, push down to the high point, the hydraulic reversing valve switches the direction, the hydraulic oil inlet kinetic energy plus the nitrogen compression kinetic energy pushes the cylinder rod down quickly and strikes the drill rod to complete the crushing work.
The number of repeated movements is closely related to the pressure of the pressing. The commonly used pressing times of the breaker have errors such as no pressing, pressing problems, low pressing times, and weak pressing. Therefore, we must master the adjustment of the pressing times of the breaking hammer and What elements are relevant and how to adjust the number of times:
The usual reciprocating motion without pressing, insufficient high-pressure oil flowing into the internal structure of the breaker without pressing, piston rod stuck, etc. are the factors that interfere with the number of pressing times. Adjust the abnormal position and restore the operation and restore it to the original pressing times. .
Under normal circumstances, if you want to adjust the number of times, you need to adjust the number of times the breaker is pressed according to the change of the stroke arrangement of the piston rod or the power device; at the same time, the pressure and hydraulic oil volume will not change. The controller is installed on the right side of the breaker cylinder. Right.
There is an adjusting screw on the top or side of the cylinder in the breaker. In order to better adjust the pressing times of the breaker, use a wrench to remove the front side of the adjusting screw on the controller, then turn the adjusting screw, and turn the adjusting screw inward. The number of pressings obtained at the end is low, and at this time, the estimated number of pressings is obtained when the adjusting screw is turned outwards for 2 turns.
