(Belgium roller press hydraulic cylinder,produced by Hebei Hengyu company）

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

Introduction to roller press hydraulic cylinder:

The pressure of the sliding surface of the roller press hydraulic cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the roller press hydraulic cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.

Before the roller press hydraulic cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

When the oil pressure of the roller press hydraulic cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.

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

Answers to some questions about roller press hydraulic cylinder:

How to control the speed of the hydraulic cylinder?
The speed of the hydraulic cylinder is only related to the flow, so the control speed is to control the flow of the hydraulic oil, which is generally adjusted by the throttle valve in the system.

How big is a 300-ton cylinder piston?
The rated pressure of the oil pump is 31.5 mpa, the nominal pressure of the hydraulic press is 3150 kN, then the calculated cross-sectional area of the cylinder: S=3150000/31500000=0.1 square meters diameter is: 2* root sign (0.1/3.14) =2*0.178 m =0.356 m 3150 kN hydraulic press is commonly equipped with 31.5 mpa 63 l/min axial piston pump. There are many variable forms of axial piston pump, and the motor size of the pump with the same flow and pressure is not uniform. 31.5 mpa 63 L/min automatic variable pump, can be equipped with 15 kW 4 stage motor; The manual variable pump needs to be equipped with 22 kW 4-stage motor.
