Daily maintenance of hydraulic cylinder

The hydraulic system needs to be stable and reliable. The working principle of the hydraulic system relies on hydraulic oil as the power transmission medium. The hydraulic oil is pressurized by the main pump and transmitted to each working device through the control valve to perform work, which plays a key role in the energy transmission of the whole machine.

In order to achieve precise control and stable performance, hydraulic components must be precision, and the quality and cleanliness of the oil are extremely high. Therefore, we have specially set up the oil filter and the oil return filter in the hydraulic system. Just as the human liver can eliminate harmful substances in the blood, the hydraulic filter can remove impurities from the system to ensure the normal operation of the hydraulic system. If there is no effective filtration of the hydraulic filter element, the impurities will directly enter the hydraulic system, and the wear of the hydraulic components will increase, resulting in insufficient system pressure and abnormal operation, which will eventually result in the vehicle being unable to be constructed and overhauled in advance, resulting in unnecessary repair costs and downtime losses. Special hydraulic oil and filter housing are sturdy and the filter holes are evenly sized. Filter paper and end cover: The first and last pleats of the filter paper are made of high-temperature special filter paper glue, the seal is complete, and the filter paper is arranged neatly and evenly. When high temperature and high pressure hydraulic oil flows through, the filter paper is not easy to float sideways, ensuring flow and filtration. In terms of materials, the special filter element of Zhonglian uses composite glass fiber filter material as the filter medium, which can always maintain superior filtration effect.

Daily maintenance points of hydraulic cylinders:

1. During the use of the cylinder, the hydraulic oil should be replaced regularly to clean the system filter to ensure cleanliness and prolong service life.

Second, each time the cylinder is used, it must be fully extended and fully retracted for 5 strokes and then loaded. In this way, the air in the system can be exhausted, and the various systems can be preheated, which can effectively avoid the presence of air or water in the system, causing gas explosion (or scorch) in the cylinder block, which will damage the seal and cause the cylinder to leak. Waiting for a fault.

Third, the system temperature is controlled. If the oil temperature is too high, the service life of the seal will be reduced. The long-term oil temperature will cause the seal to be permanently deformed or even completely ineffective.

4. Protect the outer surface of the piston rod to prevent damage to the seal by bumping and scratching. Clean the dust seal on the cylinder and the exposed piston rod to prevent the sticking on the surface of the piston rod. Dirt enters the interior of the cylinder to damage the piston, cylinder or seal.

5. Always check the joints of threads, bolts, etc., and find that the looseness is immediately tightened.

6. Lubricate the joints frequently to prevent rust or abnormal wear in the absence of oil.
