Finland tension cylinder

(Finland tension cylinder,produced by Hengyu Group)

tension cylinder are widely used in Finland,because of powerful torque,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed tension cylinder for customers from Finland.

Introduction to tension cylinder:

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.

There are some honeycomb holes in the inner wall of the tension cylinder, piston or piston rod surface. How is this formed? When we repair the tension cylinder, we can see that there are some honeycomb holes on the inner wall of the tension cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the tension cylinder is targeted to prevent. Is very necessary.

tension cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the tension cylinder is placed for a period of time, the tension cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

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:

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.

About the hydraulic cylinder wall thickness problem?
Hydraulic cylinder wall thickness calculation formula: t=PD/200St= pipe wall thickness (minimum thickness) mmP= maximum pressure kg/cm2? d= inner diameter mm? S=δ/5 safety factor δ= minimum tensile strength This case: set the cylinder material 45#, tensile strength 58kg/cm2t=(640X40)/(200X11.6)t=11mm piston output (i.e. Thrust) calculation formula: F1=PD2X(3.14/4)F1=640X42X0.785=8,038kg Note: Square numbers will not be used, all 2's in the text are square codes.
