(Angola tailplate hydraulic cylinder,produced by Hengyu Group）

tailplate hydraulic cylinder are widely used in Angola，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed tailplate hydraulic cylinder for customers from Angola.

Introduction to tailplate hydraulic cylinder:

Do not enter foreign bodies when installing the tailplate hydraulic cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

The tailplate hydraulic cylinder is mainly composed of body, piston, piston rod, tailplate hydraulic cylinder head, tailplate hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the tailplate hydraulic cylinder into two chambers, and moves reciprocally in the tailplate hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the tailplate hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the tailplate hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the tailplate hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the tailplate hydraulic cylinder bottom and the tailplate hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the tailplate hydraulic cylinder The working medium of the tailplate hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; tailplate hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the tailplate hydraulic cylinder: The buffer structure of the tailplate hydraulic cylinder is to prevent the piston from colliding with the tailplate hydraulic cylinder head at the end of the stroke.

When the tailplate hydraulic 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 tailplate hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the tailplate hydraulic 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.

If the seal of the tailplate hydraulic cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material 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 operation and improvement should be done according to the installation instructions.

Answers to some questions about tailplate hydraulic 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.

There are four cylinders in the front top of the dump truck. When the second cylinder is lifted to half the height, it suddenly falls back more than 30 cm or so, and the cylinder continues to lift.
The problem is the cylinder, the second section of the different strength of the heart. When the oil supply resistance is small, the first out, when the power is not moving, the cylinder needs to be strong, because the second section needs to pop it out after a while when the pressure is large, the oil can not keep up, so it falls back, and the oil continues to keep up.
