(Vietnam trailer hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

trailer hydraulic cylinder are widely used in Vietnam，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed trailer hydraulic cylinder for customers from Vietnam.

Introduction to trailer hydraulic cylinder:

The quality of the trailer hydraulic cylinder can not be ignored in the purchase of the trailer hydraulic cylinder. The trailer hydraulic cylinder is the main component of the trailer hydraulic cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. trailer hydraulic cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of trailer hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.

We can not just consider the price and ignore the quality when we purchase the trailer hydraulic cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the trailer hydraulic cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the trailer hydraulic cylinder is not required.

The trailer hydraulic cylinder is mainly composed of body, piston, piston rod, trailer hydraulic cylinder head, trailer hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the trailer hydraulic cylinder into two chambers, and moves reciprocally in the trailer 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 trailer hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the trailer 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 trailer 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 trailer hydraulic cylinder bottom and the trailer hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the trailer hydraulic cylinder The working medium of the trailer hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; trailer 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 trailer hydraulic cylinder: The buffer structure of the trailer hydraulic cylinder is to prevent the piston from colliding with the trailer hydraulic cylinder head at the end of the stroke.

The viscosity of the working oil used in the trailer hydraulic cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

Answers to some questions about trailer hydraulic cylinder:

What is the function of the Reza mounted master cylinder?
The role of the Resa-mounted master cylinder is to pump the concrete from the hopper to the delivery pipe and to provide sufficient concrete outlet pressure so that the concrete can reach the specified location.

How does the variable amplitude cylinder work?
The variable amplitude cylinder is generally an engineering hydraulic cylinder connected by the front and back earrings, and the telescopic expansion of the hydraulic cylinder changes the Angle of the arm of the lifting machinery to achieve the role of the variable amplitude, according to the role it plays is called the variable amplitude cylinder, and there is no variable amplitude hydraulic cylinder in the classification of hydraulic cylinders.
