tension cylinder are widely used in Denmark，because of long service life，smooth movement，high work efficiency.So our company has designed tension cylinder for customers from Denmark.

Introduction to tension cylinder:

When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the tension cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.

In the process of using the tension cylinder, sometimes such a problem will occur, the tension cylinder can not act immediately after the instruction of the tension cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil tension cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

Disassembly tension cylinder: When disassembly tension cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the tension cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the tension cylinder.

The piston rod and guide sleeve function of the tension cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

Answers to some questions about tension cylinder:

Slide weight 35 kg exit stroke 55mm, is it suitable to use 40 cylinder diameter cylinder?
The maximum output force of the 40-bore hydraulic cylinder can reach 2 tons, and whether it can be used depends on the use scenario. In addition, the problem of mechanism stuck has nothing to do with the size of the power source, and reasonable structural design and good machining and assembly accuracy are the key.

What do cylinder internal leakage and external leakage mean?
Internal leakage means that the piston seal in the cylinder is not strict, there is a leak between the two chambers of the cylinder, the oil is still in the cylinder, and the external leakage is that the oil leaks to the outside of the cylinder.
