Libya tailboard balance cylinder

(Libya tailboard balance cylinder,produced by Hengyu Hydraulic Cylinder Factory)

tailboard balance cylinder are widely used in Libya,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed tailboard balance cylinder for customers from Libya.

Introduction to tailboard balance 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 tailboard balance 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.

tailboard balance cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the tailboard balance cylinder head itself is the guide sleeve of the piston rod, the tailboard balance cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the tailboard balance cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

The quality of the tailboard balance cylinder can not be ignored in the purchase of the tailboard balance cylinder. The tailboard balance cylinder is the main component of the tailboard balance 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. tailboard balance 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 tailboard balance cylinder is deep hole processing, which has always troubled the processing personnel.

The tailboard balance cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure tailboard balance cylinder can use 20 steel pipe, and the high pressure tailboard balance cylinder can use 45 steel pipe.

Answers to some questions about tailboard balance cylinder:

Is the hydraulic cylinder leaking because there is no pressure?
HC hydraulic cylinder common leakage reasons, first: most of the reasons are because the seal surface wear or aging leads to poor sealing, so there is no pressure to operate, as long as the piston seal can be replaced. Second: It may also be the piston rod strain, repair the piston rod is good. If it is because the piston strength is not enough and the playing time is long, it is necessary to replace the piston.

Why does the hydraulic cylinder go up to the top and then slowly go down?
Leakage in the cylinder or the hydraulic valve that controls the cylinder, can be replaced and removed. Or add a pressure retaining valve to the hydraulic system to ensure pressure.
