New Zealand hydraulic cylinder,unidirectional cylinder manufacturer,unidirectional cylinder

(New Zealand unidirectional cylinder,produced by Hebei Hengyu company）

unidirectional cylinder are widely used in New Zealand，because of long service life，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed unidirectional cylinder for customers from New Zealand.

Introduction to unidirectional cylinder:

The unidirectional 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 unidirectional cylinder should pay attention to: the operation should be as far away from the unidirectional cylinder as possible, to avoid falling objects, knocking, rubbing the unidirectional cylinder coating. When cleaning the unidirectional cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the unidirectional cylinder when the oil temperature exceeds 70 ° C.

When the piston speed of the unidirectional cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the unidirectional cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

The meaning of the unidirectional cylinder model marked by the unidirectional cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the unidirectional cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the unidirectional cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

unidirectional cylinder body inspection: The inner surface of the unidirectional cylinder and the piston seal are the main factors causing the leakage in the unidirectional cylinder, if the unidirectional cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the unidirectional cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

Answers to some questions about unidirectional cylinder:

What are the problems that cause hydraulic cylinder shaking?
1, the oil supply is not smooth, the hydraulic oil filter is half blocked. 2. The oil level in the oil storage tank is lower than the minimum oil level. 3, there is air in the hydraulic system. 4, the supply oil pump is damaged or not working properly. 5, the hydraulic oil is not replaced for a long time.

Is there a way to make the cylinder stop pushing when it hits something hard during the process of pushing?
The simplest solution is to press the stop switch, this switch has a mechanical type, touch the object on the action or send a stop signal, through the operation of the motor control cylinder; There is also an induction switch, that is, when the hydraulic cylinder expands to the range of the induction switch can sense the signal, it sends a signal to let the motor act, resulting in the corresponding action of the cylinder.
