Uzbekistan hydraulic cylinder,rack cylinder manufacturer,rack cylinder(Uzbekistan rack cylinder,produced by Hengyu Hydraulic Cylinder Factory)
rack cylinder are widely used in Uzbekistan,because of long service life,smooth movement,high work efficiency.So our company has designed rack cylinder for customers from Uzbekistan.
The rack cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the rack cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the rack cylinder wall due to the stiffness and the weight of the parts, causing scars.
The rack cylinder pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.
After the rack cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.
The rack cylinder is mainly composed of body, piston, piston rod, rack cylinder head, rack cylinder bottom, piston rod head and related auxiliary devices. The piston divides the rack cylinder into two chambers, and moves reciprocally in the rack 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 rack cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the rack 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 rack 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 rack cylinder bottom and the rack cylinder head is serious, so the buffer deceleration should be set at both ends of the rack cylinder The working medium of the rack cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; rack 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 rack cylinder: The buffer structure of the rack cylinder is to prevent the piston from colliding with the rack cylinder head at the end of the stroke.
What parameters do I need to provide when purchasing hydraulic cylinders?
The main technical parameters of the hydraulic cylinder: 1. Cylinder diameter; Cylinder diameter, inner diameter size; 2. Piston rod diameter; 3. Cylinder stroke; 4. Cylinder pressure; The working pressure of the cylinder is often calculated using the test pressure, which is less than 16MPa multiplied by 1.5 and higher than 16 multiplied by 1.255. Import and export diameter and thread parameters; 6. Whether there is buffer; According to the working conditions, the piston rod extension contraction is generally buffered if the impact is large. 7. Installation method of oil cylinder, etc.
How to calculate the cross-sectional area of hydraulic cylinder?
Hydraulic cylinder cross section integral rod cavity and rodless cavity: rod cavity is cylinder inner wall cross-sectional area - piston rod cross-sectional area; The rodless cavity is the cross-sectional area of the inner wall of the cylinder. If the working pressure p and the output force F are known, the effective cross-sectional area A=F/p can be calculated.
