Luxembourg hydraulic cylinder,press hydraulic cylinder manufacturer,press hydraulic cylinder(Luxembourg press hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
press hydraulic cylinder are widely used in Luxembourg,because of smooth movement,high work efficiency,long service life.So our company has designed press hydraulic cylinder for customers from Luxembourg.
The "O" ring can be used as an auxiliary seal inside the press hydraulic 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 press hydraulic cylinder, and can be completely sealed.
The material, shape and compression of the press hydraulic cylinder seal have a great impact on the service life and work efficiency of the press hydraulic cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.
The press hydraulic cylinder is mainly composed of body, piston, piston rod, press hydraulic cylinder head, press hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the press hydraulic cylinder into two chambers, and moves reciprocally in the 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 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 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 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 press hydraulic cylinder bottom and the press hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the press hydraulic cylinder The working medium of the press hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; 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 press hydraulic cylinder: The buffer structure of the press hydraulic cylinder is to prevent the piston from colliding with the press hydraulic cylinder head at the end of the stroke.
When the 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 press hydraulic cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.
How to select the 2.5T bearing cylinder and hydraulic pump?
2,5 ton load is not heavy, you can use the rated pressure of 16 mpa gear pump, neither waste nor save cost, load/pressure = cylinder diameter, preset pressure of 8 mpa, 2500 (kg) /80 (bar) =31.25 square centimeters, in the open =63 mm, cylinder diameter can be selected 63 mm, stroke according to the situation, Hydraulic pump select gear pump, if there is a speed requirement, in order to calculate the displacement, the motor power also needs to determine the displacement of the pump to calculate.
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.
