The first method relies on the experience of the operator and the field technician of the single-arm hydraulic press. By seeing, sniffing, touching, shaking, etc., it is stipulated that when the oil turns black, it becomes dirty. It becomes cloudy to some extent and is replaced. The second method is to make...

① Set up metal mesh, install a metal inclined mesh at the bottom of the fuel tank, and use 60 mesh mesh to defoam, the best effect. ② Set up a partition to separate the oil return area from the oil suction area of the pump. The oil return is deflected by the partition, and the flow rate is slowed down, which is conducive to bubble separation and oil overflow, but this...

1. When the pump, cylinder and other hydraulic components are worn, the hose should be firmly clamped and positioned and replaced. Since worn parts will increase leakage, the pump will output full flow for a long time, and the oil will cause a large pressure drop through the narrow leakage gap. slow flow transmission...

One: The buffer device of the four-column press loses its buffering effect: the cause of the failure: the one-way valve is in a fully open state or the one-way valve seat is not tightly sealed; the seal on the piston is damaged. When the pressure in the buffer chamber rises, the hydraulic oil flows back from this chamber to the working pressure side...
