(Qatar tailplate hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

tailplate hydraulic cylinder are widely used in Qatar，because of no need for deceleration device，long service life，smooth movement.So our company has designed tailplate hydraulic cylinder for customers from Qatar.

Introduction to tailplate hydraulic cylinder:

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.

The internal leakage of the tailplate hydraulic cylinder should be prevented when the tailplate hydraulic cylinder is used. The internal leakage of tailplate hydraulic cylinder includes the leakage caused by excessive wear of tailplate hydraulic cylinder block seal, piston rod and seal cover seal and 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.

Under normal circumstances, the tailplate hydraulic cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the tailplate hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the tailplate hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the tailplate hydraulic cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the tailplate hydraulic cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

How the cavitation of the tailplate hydraulic cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the tailplate hydraulic cylinder, resulting in corrosive damage to the parts.

Answers to some questions about tailplate hydraulic cylinder:

What valve is used to control cylinder expansion?
Mainly use reversing valve, but the details of the control need hydraulic control valve, hydraulic control valve can be divided into direction control valve, pressure control valve, flow control valve. The valve controls the expansion of the cylinder is the direction control valve, that is, the reversing valve. What is the meaning of two-position three-way and three-position four-way of the reversing valve? Usually according to the different working positions that can stay after the spool is moved, it can be divided into: two-position valves, three-position valves and multi-position valves. According to the number of different slide valve channels can be divided into: two-way valve, three-way valve, four-way valve, five-way valve and multi-way valve. The name of the reversing valve is called the multi-position and multi-pass reversing valve according to its working position and the number of channels.

What is a variable amplitude cylinder?
The type of variable amplitude cylinder is: double acting piston type cylinder, single acting plunger type cylinder, double acting two-stage telescopic cylinder. Double acting piston cylinder is the most common application. The oil cylinder has two oil outlets, and when the oil is fed into the A port, the oil is returned to the B port; If the oil inlet of the B port is returned to the oil of the A port, the reciprocating movement of the piston depends on the effect of pressure. Single-acting plunger (or piston) cylinder has only one oil port, the pressure oil can only supply oil to one side of the plunger in the cylinder, the plunger moves in one direction under the action of pressure oil, and the return stroke of the plunger is driven by the gravity of the lifting arm, such as the LT1040 truck crane variable amplitude cylinder. The double-acting two-stage telescopic cylinder is a set structure, and the two-stage piston rod is like a tie rod antenna set in the cylinder barrel.
