(Belgium tension cylinder,produced by Hengyu Group）

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

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.

Analysis of commonly used seals: The wear ring and slip ring commonly used on the tension cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

The main role of the tension cylinder: the tension cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the tension cylinder realizes reciprocating motion. The structure of the tension cylinder has three categories: piston tension cylinder, plunger tension cylinder, swing tension cylinder, piston tension cylinder and plunger tension cylinder to achieve reciprocating linear motion, output speed and thrust, swing tension cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the tension cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The tension cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

When producing oil tension cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

Answers to some questions about tension cylinder:

How to calculate hydraulic cylinder flow?
Effective area of the cylinder x stroke = volume usually in liters. Volume/estimated total travel time (converted to minutes) = oil flow rate.

What does cylinder speed ratio mean?
The speed ratio of the cylinder is the ratio of the reciprocating speed of the piston, equal to the ratio of the rodless cavity area to the roded cavity area.
