Burma hydraulic cylinder,synchronous hydraulic cylinder manufacturer,synchronous hydraulic cylinder
(Burma synchronous hydraulic cylinder,produced by Hengyu Group）
synchronous hydraulic cylinder are widely used in Burma，because of no transmission clearance，powerful torque，excellent temperature resistance.So our company has designed synchronous hydraulic cylinder for customers from Burma.
The synchronous hydraulic cylinder should be vented: when the synchronous hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the synchronous hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the synchronous hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the synchronous hydraulic cylinder, the oil is best entered and discharged from the highest point of the synchronous hydraulic cylinder. synchronous hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.
synchronous hydraulic cylinder piston rod material selection and requirements: ① piston rod is usually made of 45 steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. The piston rod is generally designed as a synchronous hydraulic cylinder, if the diameter is larger, the hollow piston rod can be used. Made of No. 45 seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the working surface of the rod can be plated with hard chromium. ⑥ The piston rod and the end cap are guided by H8 ' synchronous hydraulic cylinder piston rod industry standard: piston rod diameter series of national recommended standard GB/T2348-1993. Piston rod thread size series standard GB/T2350-1980. Please refer to execute. There is no industry standard for piston rods Both the synchronous hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The synchronous hydraulic cylinder mainly outputs linear motion and force. The synchronous hydraulic cylinder has a variety of forms, according to the different characteristics of its mechanism it can be divided into piston type, plunger type and swing type three categories, according to the mode of action he can be divided into single action and double action. Piston synchronous hydraulic cylinder, plunger synchronous hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger synchronous hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.
The material, shape and compression of the synchronous hydraulic cylinder seal have a great impact on the service life and work efficiency of the synchronous 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 repair method of the synchronous hydraulic cylinder: the repair of the synchronous hydraulic cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.
Cylinder pressure calculation formula
The pressure of the cylinder at work is determined by the load, and the pressure of the physical force is equal to the force divided by the area of action (that is, P=F/S). If you want to calculate the output force of the cylinder, you can calculate it according to the formula: Set the radius of the piston (that is, the cylinder) is R (unit mm) the radius of the piston rod is r (unit mm) the working pressure P (unit MPa) the thrust of the cylinder F push =3.14*R*R*P (unit N) The pulling force of the cylinder F pull =3.14* (R*R-r* R) *P (unit N).
What does the maximum output force of the cylinder piston mean?
The maximum output of the cylinder is related to the pressure of the hydraulic system that you link to the cylinder. For example, the rated maximum output thrust of the MOB 50 cylinder is 1.3 tons and the rated pressure is 7Mpa. That is, when the input hydraulic oil pressure of the cylinder reaches 7Mpa, the maximum output thrust of the cylinder is only 0.98 tons. When the input hydraulic pressure is only 5Mpa, the maximum output thrust of the cylinder is 1.3 tons. Because the pressure of the cylinder limit is only 7Mpa, if the oil pressure of the input system exceeds 7Mpa, the cylinder can not withstand the pressure burst, and it is damaged.
