The mechanical arm grabs a little at a time and drops a little, which is a machine failure. Need maintenance.

1. Leakage of hydraulic hose Assuming that the sealing ring of the hydraulic pipeline joint is damaged, the pressure connection is not firm, or the pipe body itself is damaged, the hydraulic oil in the high-pressure cavity of the boom cylinder will eject hydraulic oil from the damaged gap, resulting in the boom gradually falling down, and finally.

2. Disadvantages of the spool of the boom reversing valve The spool of the boom reversing valve can't return to the neutral position, and the spool is seriously worn and the seal is not tight, which will cause the hydraulic oil in the high pressure chamber of the boom cylinder to flow back to the hydraulic oil tank, causing the boom to automatically descend. The mechanical arm is the most widely used automatic mechanical device in the field of robot technology. It consists of moving elements, guiding devices and arms, and can be seen in industrial manufacturing, medical care, entertainment services, military, semiconductor manufacturing and space exploration. Although they have different forms, they all have one common feature, that is, they can accept instructions and accurately locate a point in three-dimensional (or two-dimensional) space for operation.
