Uzbekistan hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder(Uzbekistan stroke adjustable cylinder,produced by Hengyu Hydraulic Cylinder Factory)
stroke adjustable cylinder are widely used in Uzbekistan,because of no need for deceleration device,long service life,smooth movement.So our company has designed stroke adjustable cylinder for customers from Uzbekistan.
The stroke adjustable cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.
At the rated pressure, the thrust of the stroke adjustable cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the stroke adjustable cylinder is related to the diameter of the stroke adjustable cylinder, but not to the stroke of the stroke adjustable cylinder. Moreover, the larger the stroke adjustable cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the stroke adjustable cylinder.
If the stroke adjustable cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.
Before the stroke adjustable cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.
What kind of seal ring we should choose for 120Mpa hydraulic cylinder?
The sealing rings used in mining machinery are high pressure, which can reach 150MPa. It is generally composed of three parts, the guide ring, the sealing body and the elastomer. It's not a special structure. It's more mature. Usually said mountain circle, bud circle.
Is rubber or polyurethane better for V-ring of hydraulic cylinder?
The hydraulic cylinder V-type seal ring is better with polyurethane, and chlorine rubber is used for various chemicals and high temperatures, especially when there are wear-resistant requirements, polyurethane rubber is needed. But the price of polyurethane rubber is much more expensive than the price of rubber. However, the V-ring material is most commonly used in nitrile and neoprene rubber, and natural rubber is used for sealing water and air. Butyl rubber is used for non-combustible hydraulic fluids and phosphate ester hydraulic fluids. The advantage is that the price is cheaper than the polyurethane material, and the disadvantage is that it is not wear-resistant and the anti-aging property is relatively poor.
