(Portugal tension cylinder,produced by Hebei Hengyu company）

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

Introduction to tension cylinder:

When the tension cylinder is in use, ensure that the tension cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

The definition of the minimum starting pressure of the tension cylinder refers to the minimum working pressure of the tension cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the tension cylinder parts and the size of the sealing friction.

Piston tension cylinder is widely used in hydraulic transmission. When the tension cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the tension cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the tension cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

The advantages and disadvantages of the tension cylinder: the surface of the tension cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the tension cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

Answers to some questions about tension cylinder:

Why does the hydraulic cylinder rebound after the rod cavity is extended into place?
The reason is that after the rod cavity is extended into place, the rod cavity and the rodless cavity are connected, so that the cylinder moves towards the rod cavity. After connecting, it is equivalent to the hydraulic oil directly driving the cylinder with an area equal to the piston rod. After the end of this problem, it is estimated that the seal is not very good, and the two cavities are connected after the pressure is increased to a certain extent; Or there is a problem in the valve, so that the two chambers are connected after reaching a certain pressure. Other phenomena: If the load is increased to a certain extent, no matter which side of the solenoid valve is energized, the cylinder will move to the rod cavity.

How long can a hydraulic cylinder work continuously?
If the maintenance is good, the service life can be extended a lot. The life of the cylinder is related to the structure of the cylinder, working pressure, stress state, hydraulic oil cleanliness, oil temperature control, maintenance and preventive measures. For example, the cylinder structure, the inner wall of the cylinder has quilting, rolling, chrome plating and other methods, the sealing parts have polyurethane rings, glay rings, metal sealing rings, etc., different combinations, the life difference is dozens of times. Metallurgical system is a typical cylinder application, in 24 hours of work, a year or more can not be shut down, in the middle of continuous work.
