(India trailer hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
trailer hydraulic cylinder are widely used in India，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed trailer hydraulic cylinder for customers from India.
The definition of the minimum stable speed refers to the minimum movement speed of the trailer hydraulic cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the trailer hydraulic cylinder that undertakes different work has different requirements for the minimum stable speed.
In the case of serious wear on the inner surface of the trailer hydraulic cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the trailer hydraulic cylinder manufacturing process for replacement. The trailer hydraulic cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.
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.
Factors that should be considered when selecting the oil seal in the trailer hydraulic cylinder: some specific factors should be taken into account when selecting the oil seal in the trailer hydraulic cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: trailer hydraulic cylinder diameter, piston rod diameter, piston rod and piston groove size, trailer hydraulic cylinder working pressure, trailer hydraulic cylinder movement speed, hydraulic system oil temperature and trailer hydraulic cylinder working environment.
Structural characteristics of the plunger cylinder? (1) The plunger hydraulic cylinder is a single-acting hydraulic cylinder, which can only move in one direction by hydraulic pressure, and the return trip of the plunger depends on other external forces or the weight of the plunger; (2) The plunger is only supported by the cylinder liner and is not in contact with the cylinder liner, so the cylinder liner is easy to process, so it is suitable for long stroke hydraulic cylinder; (3) the total pressure of the plunger during work, so it must have sufficient stiffness; (4) The weight of the plunger is often large, and it is easy to sag due to its own weight when placed horizontally, resulting in wear of the seals and guide side, so its vertical use is more favorable.
How to achieve hydraulic cylinder self-locking?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil self-locking is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.
