(Argentina tension cylinder,produced by Hengyu Hydraulic Co., Ltd）

tension cylinder are widely used in Argentina，because of no need for deceleration device，long service life，smooth movement.So our company has designed tension cylinder for customers from Argentina.

Introduction to tension cylinder:

tension cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the tension cylinder head itself is the guide sleeve of the piston rod, the tension cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the tension cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

Most of the failure of the tension cylinder is because there is a foreign body in the tension cylinder into the failure of the tension cylinder, the most problematic is that it is difficult to determine when the foreign body is into the tension cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

When using the tension cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the tension cylinder block. If the tension cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the tension cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the tension cylinder, so that the working efficiency of the tension cylinder is reduced.

When the tension cylinder is customized, if there are high requirements for the quality of the tension cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the tension cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the tension cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

Answers to some questions about tension cylinder:

How to distinguish high pressure cylinder and low pressure cylinder?
There is no special definition of the cylinder, the so-called pressure classification refers to the pump low pressure (code L) container 0.1MPa ≤p < 1.6MPa; Medium pressure (code M) container 1.6MPa ≤p < 10.0MPa; High pressure (code H) vessel 10 MPa≤p < 100 MPa; Ultra-high pressure (code U) container p≥100MPa. (1MPa=9.8Kg)

How does the variable amplitude cylinder work?
The variable amplitude cylinder is generally an engineering hydraulic cylinder connected by the front and back earrings, and the telescopic expansion of the hydraulic cylinder changes the Angle of the arm of the lifting machinery to achieve the role of the variable amplitude, according to the role it plays is called the variable amplitude cylinder, and there is no variable amplitude hydraulic cylinder in the classification of hydraulic cylinders.
