India hydraulic cylinder,rack cylinder manufacturer,rack cylinder
(India rack cylinder,produced by Hebei Hengyu company）
rack cylinder are widely used in India，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed rack cylinder for customers from India.
The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the rack cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.
The internal leakage of the rack cylinder should be prevented when the rack cylinder is used. The internal leakage of rack cylinder includes the leakage caused by excessive wear of rack cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.
When the rack cylinder needs to be stored for a period of time, please follow the recommended methods: The rack cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the rack cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil rack cylinder should not be in direct contact with water vapor for a long time. The rack cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the rack cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the rack cylinder Before working, the rack cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the rack cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.
The body of the rack cylinder on the processing process requirements: the body of the rack cylinder is an important and essential part of the rack cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the rack cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.
How to refuel pneumatic riveting cylinder?
First put the gun flat, that is, horizontally, while pushing the stroke positioning pin and loosen the back cover, rotate to the left for a maximum of five turns, and then use a wrench to loosen the oil sealing screw, slowly add the hydraulic oil and let the air out, fill up to tighten the oil sealing screw. This process of adding hydraulic oil is over.
For a cylinder with a piston diameter of 100mm and a system pressure of 10MPa, what is the thrust?
Thrust is 7850 kg. Piston area A= πR^2=7850 square mm =78.5 square cm 10MPa = 100kg/cm^2 "^2" is square F = A x P =78.5 x 100=7850 kg.
