tension cylinder Sold to America

This article mainly introduces:

America hydraulic cylinder,tension cylinder manufacturer,tension cylinder

(America tension cylinder,produced by Hebei Hengyu company）

tension cylinder are widely used in America，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed tension cylinder for customers from America.

Introduction to tension cylinder:

How the cavitation of the tension cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the tension cylinder, resulting in corrosive damage to the parts.

tension cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the tension cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

The piston seal of the tension cylinder is the main element to prevent leakage in the tension cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

The tension cylinder is not the same as the tension cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the tension cylinder can not be used as a high-power power component, but the tension cylinder can be used as a relatively large power component, or the tension cylinder system can be used.

Answers to some questions about tension cylinder:

What is hydraulic cylinder guide?
The cylinder itself can not move, the piston moves, the guide should be used to guide the mechanism connected with the piston extension end. For example, in the commonly used hydraulic press, the guide column above is used to guide the pressure plate connected with the piston.

Is it normal for the cylinder to turn black?
Cylinder blackening is a soft fault: 1. It does not affect the normal operation of your equipment. 2. Cylinder blackening involves a lot of things: hydraulic oil, oil seal material, piston rod coating, etc. These three things are not determined by the manufacturer because these three things are provided by other manufacturers. If the equipment is not due to high temperature caused by the black cylinder, you do not have to worry too much because your excavator can still work normally. If you feel uncomfortable, you can choose to replace the cylinder or replace the hydraulic oil.
