Brazil hydraulic cylinder,tension cylinder manufacturer,tension cylinder

(Brazil tension cylinder,produced by Hebei Hengyu company）

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

Introduction to tension cylinder:

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.

The scar on the sliding surface of the tension cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the tension cylinder wall. Therefore, before installation, these scars must be fully repaired.

The tension cylinder is mainly composed of body, piston, piston rod, tension cylinder head, tension cylinder bottom, piston rod head and related auxiliary devices. The piston divides the tension cylinder into two chambers, and moves reciprocally in the tension cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the tension cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the tension cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the tension cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the tension cylinder bottom and the tension cylinder head is serious, so the buffer deceleration should be set at both ends of the tension cylinder The working medium of the tension cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; tension cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the tension cylinder: The buffer structure of the tension cylinder is to prevent the piston from colliding with the tension cylinder head at the end of the stroke.

When the tension cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the tension cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

Answers to some questions about tension cylinder:

What's a minus 40 cylinder made of?
Construction with 1Cr18Ni9Ti, in low temperature conditions impact and tensile strength are very good, can withstand -100 degrees of low temperature, corrosion resistance, material price is not very high, more economic.

How to take out the diaphragm of hydraulic cylinder? The septum ring is also known as the septum sleeve, when the cylinder is too long, and does not need too much travel, add the septum sleeve, limit the stroke of the hydraulic cylinder, set on the piston rod, only contact with the guide sleeve and piston, do not cooperate with the cylinder, limit the stroke, take out the difficulty is different, need to have such a professional tool, before taking out to consult the manufacturer.
