Austria hydraulic cylinder,synchronous hydraulic cylinder manufacturer,synchronous hydraulic cylinder(Austria synchronous hydraulic cylinder,produced by Hengyu Group)
synchronous hydraulic cylinder are widely used in Austria,because of powerful torque,excellent temperature resistance,no transmission clearance.So our company has designed synchronous hydraulic cylinder for customers from Austria.
If it is found that the synchronous hydraulic cylinder lubrication is poor or the synchronous hydraulic cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the synchronous hydraulic cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the synchronous hydraulic cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the synchronous hydraulic cylinder center line. In this way, when the piston works in the synchronous hydraulic cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the synchronous hydraulic cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.
The synchronous hydraulic 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.
When the synchronous hydraulic cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.
The commonly used buffer structure of the synchronous hydraulic cylinder is composed of a piston boss and a synchronous hydraulic cylinder head groove. When the piston moves close to the synchronous 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.
What is the material of the lift cylinder?
The cylinder is composed of many parts. The cylinder also contains the seal and the installation port at both ends, the material of these two parts is not easy to determine if there is no physical object. The cylinder body is generally 20 steel, 45 steel, 27SiMn and other materials, and the piston rod is generally 40Cr, 45 steel and other materials.
What material is the piston rod of the cylinder made of?
About the piston rod: ① Piston rods are 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. ② The piston rod is generally designed as a cylinder, if the diameter is larger, the hollow piston rod can be used with 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 rod surface needs to be chrome plated.
