Vietnam spring return cylinder

(Vietnam spring return cylinder,produced by Hengyu Group)

spring return cylinder are widely used in Vietnam,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed spring return cylinder for customers from Vietnam.

Introduction to spring return cylinder:

spring return 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.

Before the spring return cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

The definition of the minimum starting pressure of the spring return cylinder refers to the minimum working pressure of the spring return cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the spring return cylinder parts and the size of the sealing friction.

The repair method of the spring return cylinder: the repair of the spring return cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.

Answers to some questions about spring return cylinder:

What material should be selected to seal the cylinder?
The choice of material for sealing is related to the working environment, strength, and medium of your equipment.

How big is a 300-ton cylinder piston?
The rated pressure of the oil pump is 31.5 mpa, the nominal pressure of the hydraulic press is 3150 kN, then the calculated cross-sectional area of the cylinder: S=3150000/31500000=0.1 square meters diameter is: 2* root sign (0.1/3.14) =2*0.178 m =0.356 m 3150 kN hydraulic press is commonly equipped with 31.5 mpa 63 l/min axial piston pump. There are many variable forms of axial piston pump, and the motor size of the pump with the same flow and pressure is not uniform. 31.5 mpa 63 L/min automatic variable pump, can be equipped with 15 kW 4 stage motor; The manual variable pump needs to be equipped with 22 kW 4-stage motor.
