Congo hydraulic cylinder,cargo elevator hydraulic cylinder manufacturer,cargo elevator hydraulic cylinder

(Congo cargo elevator hydraulic cylinder,produced by Hebei Hengyu company）

cargo elevator hydraulic cylinder are widely used in Congo，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed cargo elevator hydraulic cylinder for customers from Congo.

Introduction to cargo elevator hydraulic cylinder:

The difference between the plunger cargo elevator hydraulic cylinder and the piston cargo elevator hydraulic cylinder is that the piston in the cargo elevator hydraulic cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type cargo elevator hydraulic cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

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

Piston cargo elevator hydraulic cylinder is widely used in hydraulic transmission. When the cargo elevator hydraulic cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the cargo elevator hydraulic cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the cargo elevator hydraulic cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

The viscosity of the working oil used in the cargo elevator 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 cargo elevator hydraulic cylinder:

What is the difference between single acting hydraulic cylinder and double acting hydraulic cylinder?
Single action hydraulic cylinder is a single direction force work, the return of the plunger depends on itself or the weight of the mechanism to return. The double acting hydraulic cylinder is mainly different from the extension and retraction of the piston (the thrust and tension of the saying), which are all operated by the action of liquid pressure.

How to deal with the surface degreasing process before spraying paint after cylinder assembly, and what degreasing agent is used?
Cylinder painting, generally using the following process (note: the cylinder is best painted, do not spray powder coating, because the powder coating curing temperature is high, will lead to sealing defects and oil leakage) : Pre-degreasing - degreasing - washing - washing - pickling - washing - washing - table adjustment - phosphating - washing - washing - drying - polishing - spray primer - spray paint degreasing agent generally use neutral or weak alkaline degreasing agent, phosphating liquid generally use zinc phosphating liquid.
