1. If the temperature is relatively low, the viscosity of the hydraulic oil will be very large, which will make its fluidity worse, which will cause the hydraulic cylinder to slow down. If this happens, change the hydraulic oil with better viscosity and temperature performance.

2. Generally, this situation is because the resistance of throttling in the control pipeline is too large, the adjustment of the flow valve is not very correct, the controlled pressure is also inappropriate, and the same inlet pressure source is also disturbed. At this time, the control pressure source should be checked, and the pressure should be adjusted to the value specified by the system.

3. If the spool of the flow valve or the directional valve is stuck or the valve hole is blocked, the hydraulic cylinder is more likely to malfunction or malfunction at this time. , Check to see if there is any dirt or colloidal deposits stuck in the valve core and block the valve hole; also check the degree of wear of the valve body.

4. This situation is mainly due to leakage in the system. At this time, check the position of the liquid in the hydraulic oil tank, the seals and pipe joints on the suction side of the hydraulic pump. If this is the case, you should add hydraulic oil in time, deal with seals and pipe joints, clean or directly replace the coarse filter element.

5. If such a situation occurs, no matter how you operate the hydraulic cylinder, it will not move or move very little. See if there is dirt or colloidal deposits: check the axis of the piston rod and cylinder. It is not centered, and whether the wearing parts and seals are intact.
