(Morocco spring return cylinder,produced by Hengyu Hydraulic Cylinder Factory)

spring return cylinder are widely used in Morocco,because of no need for deceleration device,excellent temperature resistance,no transmission clearance.So our company has designed spring return cylinder for customers from Morocco.

Introduction to spring return cylinder:

In recent years, the processing process of the spring return 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.

There are some honeycomb holes in the inner wall of the spring return cylinder, piston or piston rod surface. How is this formed? When we repair the spring return cylinder, we can see that there are some honeycomb holes on the inner wall of the spring return cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the spring return cylinder is targeted to prevent. Is very necessary.

In the case of serious wear on the inner surface of the spring return cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the spring return cylinder manufacturing process for replacement. The spring return cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

Repair method of small range wear of oil spring return cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

Answers to some questions about spring return cylinder:

Why hydraulic cylinder load can not rise?
The hydraulic cylinder does not top up indicates that the pressure of the working chamber of the hydraulic cylinder is insufficient, and the following circumstances can lead to insufficient pressure: 1) The relief valve of the hydraulic system cannot establish pressure, elimination method: check whether the pressure setting screw of the relief valve is screwed to the appropriate position. If it is an electromagnetic relief valve, please check the power-on condition. 2) The hydraulic system pipeline is connected incorrectly, when P and T are connected, this must be checked and excluded; 3) Excessive leakage in the hydraulic cylinder, resulting in (only for double-acting cylinders); 3) No hydraulic oil into the working chamber of the hydraulic cylinder, elimination method: first disassemble the hydraulic pipe connecting the reversing valve and the hydraulic cylinder, and then control the reversing valve, and observe whether there is hydraulic oil flowing out of the reversing valve.

How to calculate the speed of cylinder weight decline?
To reduce the weight of the cylinder, the necessary condition is that the weight of the piston rod + external load is greater than the friction between the seal ring and the cylinder. There are many reasons for this, first of all, consider the reasons of the cylinder itself, the piston in the cylinder and the sealing ring on the piston rod will play a reaction force on the weight of the cylinder (because of friction), which depends on the tightness of the sealing ring and the cylinder. Secondly, what is connected under the piston rod of the cylinder and how much weight there is. And the way the cylinders are arranged, is it completely vertical. Anyway, in fact, the most important thing is to see how much the bore of the oil hole of the piston rod cavity of your cylinder is. For example, if the hole in the lower chamber of the cylinder is small, as thin as a needle, then its descent rate will be slow.
