Nigeria hydraulic cylinder,vehicle hydraulic cylinder manufacturer,vehicle hydraulic cylinder

(Nigeria vehicle hydraulic cylinder,produced by Hebei Hengyu company）

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

Introduction to vehicle hydraulic cylinder:

When purchasing the vehicle hydraulic cylinder, try to clarify the following parameters of the vehicle hydraulic cylinder: A. vehicle hydraulic cylinder diameter, rod diameter, stroke; B. Working pressure or vehicle hydraulic cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right vehicle hydraulic cylinder type can be found accurately and quickly.

The vehicle hydraulic cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the vehicle hydraulic cylinder should pay attention to: the operation should be as far away from the vehicle hydraulic cylinder as possible, to avoid falling objects, knocking, rubbing the vehicle hydraulic cylinder coating. When cleaning the vehicle hydraulic cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the vehicle hydraulic cylinder when the oil temperature exceeds 70 ° C.

The difference between the plunger vehicle hydraulic cylinder and the piston vehicle hydraulic cylinder is that the piston in the vehicle 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 vehicle hydraulic cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

Most of the failure of the vehicle hydraulic cylinder is because there is a foreign body in the vehicle hydraulic cylinder into the failure of the vehicle hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the vehicle hydraulic cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

Answers to some questions about vehicle hydraulic cylinder:

What is the meaning of dead volume in hydraulic cylinder?
Closed volume, also known as dead zone volume Positive displacement pump is dependent on the change of sealing working volume to achieve suction and pressure oil, in order not to make the suction and pressure oil cavity interworking, there is an oil sealing area between the suction and pressure oil cavity, when the sealing working volume passes through the oil sealing area, neither pressure oil cavity nor oil suction cavity communication, forming a closed sealing volume. The unloading groove is opened, and the grooving principle is that the sealing volume decreases and the oil pressure chamber is communicated, and the sealing volume increases and the oil suction chamber is communicated.

How to exhaust hydraulic cylinder?
Exhaust: The hydraulic system generally does not have exhaust, the use of the tank can exhaust, the oil operation will bring the gas back to the tank, and the tank can be communicated with the atmosphere. The gas will escape from the oil.
