(Ghana tension cylinder,produced by Hengyu Group）

tension cylinder are widely used in Ghana，because of excellent temperature resistance，no transmission clearance，simple structure and reliable operation.So our company has designed tension cylinder for customers from Ghana.

Introduction to tension cylinder:

Under normal circumstances, the tension cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the tension cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the tension cylinder and the end cover, the piston and the piston rod, the piston and the tension cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the tension cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

The tension cylinder pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.

If the seal of the tension cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.

The tension cylinder should be vented: when the tension cylinder is installed or parked for a long time to work again, the air will penetrate into the tension cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the tension cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the tension cylinder, the oil is best entered and discharged from the highest point of the tension cylinder. tension cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Answers to some questions about tension cylinder:

What is the relationship between medium cylinder and side cylinder ratio of forklift truck?
The middle cylinder and the side cylinder seem to have no relationship, as long as the lifting speed required by the design can be ensured, but the diameter of the cylinder can not be too thin, so as to avoid the middle cylinder acting first when the high gantry vibration lifting, and then the two cylinders acting again.

Why are the hydraulic cylinders out of sync? The reasons for the unsynchronous operation are as follows: 1, the deviation of the external load of the two cylinders, such as the different resistance and friction of the two cylinders will lead to imbalance. The displacement of the cylinder with low resistance will be larger. 2, the difference in internal friction, such as the difference between the piston and the cylinder of each cylinder, the friction between the piston rod and the seal causes the cylinder to be out of sync. 3. The different resistance of hydraulic oil along the pipeline of the two cylinders causes the cylinder to be out of sync. 4, the deviation of the control original adjustment causes the deviation of the flow to be out of sync, such as the use of an independent throttle valve for each cylinder will appear the difference in the flow of oil in and out of the oil affecting the synchronization of the two cylinders. 5. The cylinder support point of the supported part is initially different.
