(Sri Lanka roller press hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）

roller press hydraulic cylinder are widely used in Sri Lanka，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed roller press hydraulic cylinder for customers from Sri Lanka.

Introduction to roller press hydraulic cylinder:

The viscosity of the working oil used in the roller press hydraulic cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

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.

When the roller press hydraulic cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the roller press hydraulic cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

The roller press hydraulic cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the roller press hydraulic cylinder, bite. Elimination method: When installing the roller press hydraulic cylinder, ensure that the axis position of the roller press hydraulic cylinder is consistent with the direction of movement; Make the load borne by the roller press hydraulic cylinder as far as possible through the roller press hydraulic cylinder axis, to avoid the phenomenon of eccentricity.

Answers to some questions about roller press hydraulic cylinder:

When the superimposed hydraulic control valve is added to the bottom of a solenoid valve and a double directional throttle valve, why does the cylinder shock on the return trip?
The stack hydraulic control check valve must be added above the stack one-way throttle valve.

What diameter cylinder is needed for a force of 5 tons?
It depends on the pressure of your system pump. If the normal working pressure of the system is about 8MPa, then the diameter of the cylinder should be 100 mm.
