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

Introduction to tension cylinder:

The tension cylinder is mainly composed of body, piston, piston rod, tension cylinder head, tension cylinder bottom, piston rod head and related auxiliary devices. The piston divides the tension cylinder into two chambers, and moves reciprocally in the tension cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the tension cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the tension cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the tension cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the tension cylinder bottom and the tension cylinder head is serious, so the buffer deceleration should be set at both ends of the tension cylinder The working medium of the tension cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; tension cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the tension cylinder: The buffer structure of the tension cylinder is to prevent the piston from colliding with the tension cylinder head at the end of the stroke.

The repair method of the tension cylinder: the repair of the tension cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.

If it is found that the tension cylinder lubrication is poor or the tension cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the tension cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the tension cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the tension cylinder center line. In this way, when the piston works in the tension cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the tension cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

The definition of the minimum stable speed refers to the minimum movement speed of the tension cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the tension cylinder that undertakes different work has different requirements for the minimum stable speed.

Answers to some questions about tension cylinder:

What is the thin cylinder used for?
The principle is no different from ordinary cylinders, that is, the installation space is small, the formation is small, and it is suitable for some special occasions. For example, the space is compact and the place of small travel is used.

Why are two cylinders not balanced with the balance valve?
Balancing valve is only suitable for occasions with low synchronous accuracy requirements, and proportional valves are recommended for occasions with high precision requirements.
