(Denmark swager cylinder,produced by Hebei Hengyu company）

swager cylinder are widely used in Denmark，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed swager cylinder for customers from Denmark.

Introduction to swager cylinder:

When the swager cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the swager cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the swager cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the swager cylinder can meet the requirements by grinding. However, the life and reliability of this repair swager cylinder are not high.

The meaning of the swager cylinder model marked by the swager cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the swager cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the swager cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

The swager cylinder is mainly composed of body, piston, piston rod, swager cylinder head, swager cylinder bottom, piston rod head and related auxiliary devices. The piston divides the swager cylinder into two chambers, and moves reciprocally in the swager 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 swager cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the swager 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 swager 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 swager cylinder bottom and the swager cylinder head is serious, so the buffer deceleration should be set at both ends of the swager cylinder The working medium of the swager cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; swager 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 swager cylinder: The buffer structure of the swager cylinder is to prevent the piston from colliding with the swager cylinder head at the end of the stroke.

The "O" ring can be used as an auxiliary seal inside the swager cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the swager cylinder, and can be completely sealed.

Answers to some questions about swager cylinder:

What is hydraulic cylinder guide?
The cylinder itself can not move, the piston moves, the guide should be used to guide the mechanism connected with the piston extension end. For example, in the commonly used hydraulic press, the guide column above is used to guide the pressure plate connected with the piston.

How to calculate cylinder pressure?
Hydraulic pressure area of cylinder × hydraulic pressure = output force of cylinder 200mm=20cm 100mm=10cm 15Mpa=150Kg/cm2 Cylinder thrust: 3.14×10×10 area ×150 pressure =47100Kg=47.1t cylinder pulling force: 3.14×(10×10-5×5) Area ×150 pressure =35325Kg=35.325t The above calculation did not consider the resistance of oil return, because you did not provide oil return pressure. But the impact should be small.
