    During the use of the spiral swing cylinder, there will be malfunctions or malfunctions. What causes it? How to solve it?
    1. The spool is stuck or the valve hole is blocked. When the flow valve or directional valve spool is blocked or the valve hole is blocked, the hydraulic cylinder is prone to malfunction or malfunction. At this time, check the oil contamination; check whether the dirt or colloidal deposits are stuck in the valve plug or block the valve hole; check the valve body for wear.
    2. The piston rod is stuck with the cylinder or the hydraulic cylinder is blocked. Regardless of how it is manipulated at this time, the hydraulic cylinder does not move or moves very little. At this time, you should check whether the seals of the piston and the piston rod are too tight, whether they have entered the dirt and colloidal deposits: whether the axis of the piston rod and the cylinder are aligned, and whether the wearing parts and seals have failed.
    3. The control pressure of the hydraulic system is too low. Throttling resistance in the control line may be too large, the flow valve may be improperly adjusted, the control pressure may be inappropriate, and the pressure source may be disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system.
    4. Air enters the hydraulic system. Mainly because of a leak in the system. At this time, the liquid level of the hydraulic oil tank, the seals and pipe joints on the suction side of the hydraulic pump, and whether the primary suction filter is too dirty should be checked. If so, replenish hydraulic oil, handle seals and pipe joints, and clean or replace the coarse filter element.
    5. The initial movement of the hydraulic cylinder is slow. When the temperature is low, the hydraulic oil has a large viscosity and poor fluidity, which causes the hydraulic cylinder to move slowly. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance. At low temperature, you can use a heater or the machine to heat it to increase the oil temperature at startup.
    The above is the introduction of the reasons for the malfunction of the spiral swing cylinder and the solutions. I hope it will be helpful to everyone.
