Heat treatment hard chrome rod introduction

Generally, thermal treatment hard chromium bar consists of such two types as hydraulic and gas-filled and a kind of shock absorber with changeable damping. In terms of structure, it can be divided into such two types as single-barrel and double-barrel, mainly including such three kinds as single-barrel air-pressure shock absorber, double-barrel oil-pressure shock absorber and double-barrel oil-gas-pressure shock absorber.


TYPES

Hydraulic shock absorber: The hydraulic shock absorber is a kind of shock absorber widely used in automobile suspension system. Its shock-absorbing principle is to make the oil liquid inside the shell of the shock absorber flow into another inner chamber from some narrow pores of inner chamber repeatedly by virtue of the reciprocating motion of the piston of shock absorber inside the cylinder barrel of the shock absorber so as to achieve the shock absorption through the inner friction of liquid molecules and the friction between liquid and inner wall.

Gas-filled shock absorber: The gas-filled shock absorber is a new type shock absorber, in which a floating piston is mounted under the cylinder barrel of the shock absorber. The closed gas chamber formed on the end of floating piston and cylinder barrel is filled with high-pressure nitrogen. A large section O type seal ring is mounted on the floating piston for fully separating the oil and gas. The working piston is mounted with compression valve and rebound valve which will change the cross-sectional area of channel along with speed of movement.

While a car is vibrating in motion on the road, the working piston of the shock absorber will make a reciprocating motion to generate an oil pressure difference between upper chamber and lower chamber of working piston so that the pressure oil flows back and forth by pushing the compression valve and rebound valve open and achieve the effect of vibration reduction by means of resistance arisen from the movement.

Double-barrel shock absorber: The double-barrel shock absorber consists of two barrels: inner and outer barrels, with piston moving inside the inner barrel for maintaining the oil balance inside the inner barrel through its exchange with outer barrel.

Single-barrel shock absorber: The single-barrel shock absorber is relatively simple in structure, with a floating piston mounted under the shock absorber so as to form a closed gas chamber under the floating piston. It is filled with high-pressure nitrogen.
