Kuwait hydraulic cylinder,push and pull the cylinder manufacturer,push and pull the cylinder

(Kuwait push and pull the cylinder,produced by Hebei Hengyu company）

push and pull the cylinder are widely used in Kuwait，because of no transmission clearance，powerful torque，smooth movement.So our company has designed push and pull the cylinder for customers from Kuwait.

Introduction to push and pull the cylinder:

The piston rod and guide sleeve function of the push and pull the cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

The material of the sliding part of the push and pull the cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

The push and pull the cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the push and pull the cylinder, bite. Elimination method: When installing the push and pull the cylinder, ensure that the axis position of the push and pull the cylinder is consistent with the direction of movement; Make the load borne by the push and pull the cylinder as far as possible through the push and pull the cylinder axis, to avoid the phenomenon of eccentricity.

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

Answers to some questions about push and pull the cylinder:

How to calculate cylinder speed?
If there is a throttle valve, the cylinder speed will be adjustable. When the throttle is fully opened, the speed of the cylinder reaches the maximum: maximum speed = oil pump displacement ÷ cylinder cavity cross-sectional area The displacement of the oil pump is a main indicator, which can be found on the nameplate, and some can also be known by the oil pump model; The cross-sectional area of the cylinder cavity can be easily calculated. Just make sure the units are the same. And because the cross-sectional area of the rod cavity and the rodless cavity of the cylinder is different, the speed of advance and retreat may also be different.

How to calculate the inner diameter of the hydraulic cylinder?
These two parameters need the following information to decide: 1, pump displacement, speed (to get the actual output flow of the pump) 2, three and time requirements (lift time, drop time takes a few seconds) and then view the close cylinder series according to the results. Select the right cylinder.
