1. Hydraulic cylinder, must it work in the limit position?
The hydraulic cylinder does not have to work in the extreme position, it can work in other positions, we call it the working position of the hydraulic cylinder. Generally speaking, it is one. If it requires two, it can be realized by using a three-position four-way valve, a stroke switch and a PLC.
2. The lifting speed of hydraulic cylinders is inconsistent. What are the specific reasons?
If there is a problem that the lifting speed is inconsistent in the hydraulic cylinder, then for specific reasons, there are:
Reason one: The pressure inside the hydraulic cylinder is set too high, causing the oil pump to wear too fast or prematurely, and further, its efficiency is lowered, which causes this problem of the cylinder.
The second reason: the oil temperature in the cylinder is too high, so that the viscosity of the oil is lowered, and further, there is a problem of internal leakage and the like, and thus the hydraulic cylinder lifting speed is inconsistent.
3. Hydraulic cylinder mechanical efficiency, what does it mean?
The mechanical efficiency of the hydraulic cylinder, which is simply understood, refers to the loss of the hydraulic cylinder during the working process, and the cause is mainly friction, and sometimes it is inevitable. However, under normal circumstances, the mechanical efficiency of the hydraulic cylinder is required to reach 98%, which
It will be guaranteed.
