Italy hydraulic cylinder,stern plate hydraulic cylinder manufacturer,stern plate hydraulic cylinder(Italy stern plate hydraulic cylinder,produced by Hengyu Group)
stern plate hydraulic cylinder are widely used in Italy,because of smooth movement,no need for deceleration device,long service life.So our company has designed stern plate hydraulic cylinder for customers from Italy.
When the stern plate hydraulic cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the stern plate hydraulic cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.
Before the stern plate hydraulic cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.
The commonly used buffer structure of the stern plate hydraulic cylinder is composed of a piston boss and a stern plate hydraulic cylinder head groove. When the piston moves close to the stern plate hydraulic cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.
At the rated pressure, the thrust of the stern plate hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the stern plate hydraulic cylinder is related to the diameter of the stern plate hydraulic cylinder, but not to the stroke of the stern plate hydraulic cylinder. Moreover, the larger the stern plate hydraulic cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the stern plate hydraulic cylinder.
How to set up the one-way cylinder hydraulic system?
Single acting oil cylinder, that is, an oil cylinder with an oil port, can use two three-way valves to control the cylinder action. The three oil ports are respectively connected to P (oil pump), A (oil cylinder), and T (oil tank). If the oil pump is to run continuously, an electromagnetic relief valve can be added. When the cylinder is not moving, the relief valve can unload the oil pump. You can also add a three-way four-way valve, the middle function is unloaded, two outlets: A connected to the fuel tank, B connected to the cylinder.
What is a constant velocity cylinder? What is the difference between hydraulic cylinder and constant velocity cylinder?
The constant speed cylinder should be the same as the speed of the piston rod extension and withdrawal cylinder is called the constant speed cylinder. The difference between it and the ordinary hydraulic cylinder is that the ordinary hydraulic cylinder only has a piston rod extended out, and the general extension speed is slow and the recovery speed is fast, because of the relationship between the effective area. Effective area of piston chamber > Effective area of piston rod chamber. The effective area on both sides of the constant speed cylinder is the same, because there are piston rods sticking out at both ends. The application of constant speed cylinder is most common in grinding machines.
