Turkmenistan large bore cylinder

(Turkmenistan large bore cylinder,produced by Hengyu Group)

large bore cylinder are widely used in Turkmenistan,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed large bore cylinder for customers from Turkmenistan.

Introduction to large bore cylinder:

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 large bore 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.

When the large bore cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the large bore cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

large bore cylinder installation precautions: Before installing the large bore cylinder into the system, the parameters on the large bore cylinder label should be compared with the parameters when ordering. The base of the large bore cylinder must have sufficient stiffness, otherwise the large bore cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

The quality of the large bore cylinder can not be ignored in the purchase of the large bore cylinder. The large bore cylinder is the main component of the large bore cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. large bore cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of large bore cylinder is deep hole processing, which has always troubled the processing personnel.

Answers to some questions about large bore cylinder:

How to select swing cylinder? Under what conditions are they designed and selected?
1, determine the system parameters: ① the weight and the required force; ② Nominal working pressure and range; ③ The time required to travel this distance; 4 oil medium 2, installation method: select the appropriate way for the specific application 3, cylinder diameter and working pressure: determine the cylinder diameter and provide the necessary force required by the system pressure 4, piston rod: determine the minimum piston rod diameter required to withstand the longitudinal bending force, select the appropriate piston rod end and piston rod end thread 5, piston: Whether the seal type is suitable for the application 6, buffer: choose the buffer requirements as appropriate.

What material is the piston rod of the cylinder made of?
About the piston rod: ① Piston rods are usually made of 45# steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. ② The piston rod is generally designed as a cylinder, if the diameter is larger, the hollow piston rod can be used with 45# seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the rod surface needs to be chrome plated.
