(Tanzania tension cylinder,produced by Hebei Hengyu company）

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

Introduction to tension cylinder:

Do not enter foreign bodies when installing the tension cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

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.

When the tension cylinder needs to be stored for a period of time, please follow the recommended methods: The tension cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the tension cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil tension cylinder should not be in direct contact with water vapor for a long time. The tension cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the tension cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the tension cylinder Before working, the tension cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the tension cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

If the tension cylinder slips or crawls, please check whether there is astringency inside the tension cylinder, because the internal parts of the tension cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the tension cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the tension cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.

Answers to some questions about tension cylinder:

How to calculate the speed of cylinder weight decline?
To reduce the weight of the cylinder, the necessary condition is that the weight of the piston rod + external load is greater than the friction between the seal ring and the cylinder. There are many reasons for this, first of all, consider the reasons of the cylinder itself, the piston in the cylinder and the sealing ring on the piston rod will play a reaction force on the weight of the cylinder (because of friction), which depends on the tightness of the sealing ring and the cylinder. Secondly, what is connected under the piston rod of the cylinder and how much weight there is. And the way the cylinders are arranged, is it completely vertical. Anyway, in fact, the most important thing is to see how much the bore of the oil hole of the piston rod cavity of your cylinder is. For example, if the hole in the lower chamber of the cylinder is small, as thin as a needle, then its descent rate will be slow.

How does the clamping cylinder work?
Hydraulic transmission principle: oil as the working medium, through the change of the sealing volume to transfer movement, through the internal pressure of the oil to transfer power. 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. 2, The executive part - the hydraulic pump input oil pressure energy into the mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3, The control part - used to control and adjust the oil pressure, flow and flow direction. For example: pressure control valve, flow control valve and direction control valve. 4, The auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.
