Precautions for disassembly and maintenance of single piston rod hydraulic cylinder

 

In the whole process of disassembly and assembly, pay attention to the connection between the guiding sleeve, the piston rod and the engine cylinder block, the position of the card key and the association with the assembly line of the surrounding parts, the sealing position and the basic principle of the sealing of the hydraulic cylinder, and the construction method and principle of the cache structure of the hydraulic cylinder. All parts must be cleaned with gasoline or diesel engine as well. Pay attention to check whether the sealing components, yellow card ring and other spare parts are damaged, and should be replaced when necessary.

Single piston rod hydraulic cylinder

 

 

 

The assembly line should pay attention to adjusting the sealing ring clamping equipment, so that it is tight and loose, to ensure that the hydraulic cylinder can be driven by hand, and in the application can not have too much leakage (leakage with trace analysis is allowed).

When removing the hydraulic cylinder, we should pay attention to whether the sealing ring is too damaged, embrittlement and loss of ductility, and whether the lip is damaged; Check whether the surface layer of cylinder liner, hydraulic cylinder, guide sleeve and other parts has vertical pull marks or excessive damage on one side and repair it.

Mechanical faults of hydraulic cylinders include crawling motion, impact, slow reduction of speed and external leakage. Supplier: China Hudraulic manifold Block manufacturer, supplier of aluminum manifold Block

 

 

 

 

Crawling movement will be caused by gas intrusion or v-ring cylinder head pressure is too tight or too loose or the parallelism between the cylinder and the piston rod or because the cylinder is bent.

 

 

 

Impact will be because the gap between the gap sealing piston rod and the cylinder liner is too large, the relief valve will lose its effect or because the edge cache of the product is not working, and the adjustment function is not available.

Single piston rod hydraulic cylinder structure

 

 

 

The speed will slowly decrease because the piston rod and cylinder liner interfit gap is too large or the sealing ring is destroyed, so that the high pressure and low pressure cavity is communicated; The middle part of the work is not symmetrical, resulting in the deviation of some geometric figures, and the loss of high pressure and low pressure chamber tightness; Cylinder end hydraulic cylinder skeleton seal pressure is too tight or hydraulic cylinder bending to improve the sliding friction; Cylinder wall contusion is more serious; When the oil temperature is too high, the viscosity decreases and the leakage increases, resulting in the deceleration of the hydraulic cylinder rate.

Gear oil exposure will be damaged or invalid because of the o-ring between the cylinder head and cylinder suite; The guide sleeve has cracks; The sealing damage between the guide sleeve and the hydraulic cylinder; Hydraulic cylinder surface damage, etc. Common faults need to be purposefully taken and effectively cleared.
