Uganda hydraulic cylinder,supporting cylinder manufacturer,supporting cylinder(Uganda supporting cylinder,produced by Hebei Hengyu company)
supporting cylinder are widely used in Uganda,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed supporting cylinder for customers from Uganda.
The piston seal of the supporting cylinder is the main element to prevent leakage in the supporting cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.
supporting cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.
supporting cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the supporting cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the supporting cylinder. c. The supporting cylinder seal is extruded, if the O-ring is obviously extruded at the supporting cylinder seal, replace the supporting cylinder seal.
The material of the sliding part of the supporting cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.
What is the cylinder with rod cavity, what is the rodless cavity.
The rod cavity is the end of the piston rod, the rodless cavity is the end without the piston rod.
How to distinguish large cavity and small cavity of excavator rod cylinder ?
Single rod piston cylinder is a form of cylinder that is used relatively most, and the boom, bucket, dozer shovel cylinder are all in this form. Among them, the rodless cavity is also called the large cavity, and the rodless cavity is also called the small cavity. Therefore, the cylinder cavity on the side with the exposed piston rod is the small cavity, and the cylinder cavity on the side without the exposed rod is the large cavity.
