What are the disadvantages of hydraulic cylinder clamping?
2020-10-20
The hydraulic pump, hydraulic system and hydraulic components usually adopt the cylindrical slide valve structure, and the valve core and valve body should be integrated in theory. Therefore, no matter how much pressure it is under, the force required to move the valve core only needs to overcome the viscous friction force. The value should be very small (0.5~5N), but this is not the case, especially in the medium and high pressure system,
