(Egypt non-standard special type cylinder,produced by Hengyu Hydraulic Cylinder Factory）

non-standard special type cylinder are widely used in Egypt，because of no need for deceleration device，smooth movement，long service life.So our company has designed non-standard special type cylinder for customers from Egypt.

Introduction to non-standard special type cylinder:

In recent years, the processing process of the non-standard special type 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 hydraulic oil is not pumped into the non-standard special type cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the non-standard special type cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

The body of the non-standard special type cylinder on the processing process requirements: the body of the non-standard special type cylinder is an important and essential part of the non-standard special type cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the non-standard special type cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

non-standard special type cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the non-standard special type cylinder is placed for a period of time, the non-standard special type cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

Answers to some questions about non-standard special type cylinder:

What are the main technical parameters of the hydraulic cylinder?
Parameters are as follows: 1, cylinder diameter, inner diameter size; 2, import and export diameter and thread parameters; 3, piston rod diameter; 4, cylinder pressure, cylinder working pressure, calculation is often used test pressure, less than 16MPa multiplied by 1.5, higher than 16MPa multiplied by 1.25. 5, cylinder stroke; 6. Is there a buffer? According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7, the installation of the cylinder.

Why do two hydraulic cylinders lift out of sync?
There may be several situations (do not know the result of the equipment, may not be accurate) 1, whether the slow one is worn 2, whether there is air in the slow cylinder 3, if the two cylinders are supplied by the same oil port, whether the slow joint is blocked (some processing residue will reach a certain oil port under a certain coincidence condition, This situation will not happen if it is not necessarily good before) 4, the oil seal in the slow cylinder leaks, causing the feed oil to leak from the return oil end. Point 4 is most likely because it is invisible and a technical failure. If it is a dual oil feed (separate oil feed), it is also necessary to check the oil supply system and the oil return system (valve type).
