(Germany 500 tons hydraulic press cylinder,produced by Hengyu Group）

500 tons hydraulic press cylinder are widely used in Germany，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed 500 tons hydraulic press cylinder for customers from Germany.

Introduction to 500 tons hydraulic press cylinder:

The 500 tons hydraulic press cylinder is mainly composed of body, piston, piston rod, 500 tons hydraulic press cylinder head, 500 tons hydraulic press cylinder bottom, piston rod head and related auxiliary devices. The piston divides the 500 tons hydraulic press cylinder into two chambers, and moves reciprocally in the 500 tons hydraulic press 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 500 tons hydraulic press cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the 500 tons hydraulic press 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 500 tons hydraulic press 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 500 tons hydraulic press cylinder bottom and the 500 tons hydraulic press cylinder head is serious, so the buffer deceleration should be set at both ends of the 500 tons hydraulic press cylinder The working medium of the 500 tons hydraulic press cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; 500 tons hydraulic press 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 500 tons hydraulic press cylinder: The buffer structure of the 500 tons hydraulic press cylinder is to prevent the piston from colliding with the 500 tons hydraulic press cylinder head at the end of the stroke.

500 tons hydraulic press cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

In use, the 500 tons hydraulic press cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the 500 tons hydraulic press cylinder.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular 500 tons hydraulic press cylinder action. Troubleshooting method: Replace the rubber hose.

Answers to some questions about 500 tons hydraulic press cylinder:

What are the connection methods of the hydraulic cylinder? The connection modes of the cylinder and the actuator are earring connection, hinge shaft connection, thread connection, etc. The connection modes of tubing and cylinder are threaded connection, flange connection, etc.

Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.
