Tunisia steering cylinder

(Tunisia steering cylinder,produced by Hengyu Hydraulic Cylinder Factory)

steering cylinder are widely used in Tunisia,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed steering cylinder for customers from Tunisia.

Introduction to steering cylinder:

Classification of steering cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

In recent years, the processing process of the steering cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

When the steering cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the steering cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the steering cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

Causes and countermeasures of oil steering cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the steering cylinder will lead to premature wear of the piston seal, replace the piston seal; If the steering cylinder is visibly scarred, the steering cylinder must be replaced. It can be pressurized at one end of the steering cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most steering cylinder piston drift may not come from the steering cylinder, the above method to determine the steering cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

Answers to some questions about steering cylinder:

What is the meaning of cylinder ejection on the injection mold, and what is the difference between cylinder ejection and ordinary ejection?
Usually requires the front die ejection will use the cylinder to drive the thimble plate to achieve the ejection of the thimble. There is also a case that the mold is very large or long, and the balance of the ejector rod of the injection molding machine is not enough, and the cylinder ejector will also be used.

Why can't the hydraulic cylinder be pulled back after pushing to the limit?
May be long-term use to the limit position, resulting in serious wear caused! The solution is to add the stroke switch or disassemble and add gaskets before and after the piston.
