(Morocco tailplate hydraulic cylinder,produced by Hebei Hengyu company）

tailplate hydraulic cylinder are widely used in Morocco，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed tailplate hydraulic cylinder for customers from Morocco.

Introduction to tailplate hydraulic cylinder:

If the tailplate hydraulic cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the tailplate hydraulic cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow tailplate hydraulic cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the tailplate hydraulic cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the tailplate hydraulic cylinder includes the leakage caused by excessive wear of the tailplate hydraulic cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and tailplate hydraulic cylinder, and the phenomenon of "pulling the tailplate hydraulic cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

The advantages and disadvantages of the tailplate hydraulic cylinder: the surface of the tailplate hydraulic cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the tailplate hydraulic cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the tailplate hydraulic cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

The piston rod of the tailplate hydraulic cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

Answers to some questions about tailplate hydraulic cylinder:

How many kinds of cylinder seal repair kit are there?
Very much, a wide variety of imported and domestic, J type, UHS, DHS, O-ring, Sterseal, etc., as well as support bars, materials are different, according to the size of the pressure selection is different, the appearance of the structure is different, the size is a variety, maintenance is generally selected according to the needs of the cylinder.

What do cylinder internal leakage and external leakage mean?
Internal leakage means that the piston seal in the cylinder is not strict, there is a leak between the two chambers of the cylinder, the oil is still in the cylinder, and the external leakage is that the oil leaks to the outside of the cylinder.
