Product Description:

1. The valve core is stuck or the valve hole is blocked. When the flow valve or directional valve core is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or malfunction. The oil contamination should be checked at this time. Check whether the dirt or colloidal sediment is sticking to the valve core or blocking the valve hole; Check the wear condition of valve body, clean and replace system filter, clean oil tank and replace hydraulic medium.

2. The piston rod is stuck with the harvester hydraulic cylinder is blocked. No matter how to operate at this time, the hydraulic cylinder does not move or little action. Then should check if the piston and piston rod seal is too tight, whether sediment into the dirt and glue: whether the axis of the piston rod and cylinder of the wearing parts and seal failure, whether the load is too big.

3. The control pressure of the hydraulic system is too low. The throttle resistance in the control pipeline may be too large, the flow valve is not properly regulated, the control pressure is not appropriate, and the pressure source is disturbed. At this point, the control pressure source should be checked to ensure that the pressure is regulated to the system.

4. Enter air in the hydraulic system. It's mainly because of leaks in the system. At this point, the liquid level of the hydraulic oil tank should be checked. Sealing parts and pipe joints on the oil suction side of the hydraulic pump should be checked. In this case, the hydraulic oil should be supplemented, the sealing and pipe joints should be treated, and the thick filter element should be cleaned or replaced.

5. The initial movement of the hydraulic cylinder is slow. Under the condition of low temperature, the hydraulic oil has a high viscosity and poor fluidity, leading to the slow movement of the hydraulic cylinder. Improved method is to replace glue good hydraulic oil temperature performance, can use in the low temperature heater heating or by machine itself to improve the oil temperature of startup, system normal working oil temperature should be kept at about 40 ℃.
