Finland hydraulic cylinder,flying wing compartment hydraulic cylinder manufacturer,flying wing compartment hydraulic cylinder(Finland flying wing compartment hydraulic cylinder,produced by Hengyu Group)
flying wing compartment hydraulic cylinder are widely used in Finland,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed flying wing compartment hydraulic cylinder for customers from Finland.
flying wing compartment 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 flying wing compartment 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 ' flying wing compartment 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 flying wing compartment hydraulic cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The flying wing compartment hydraulic cylinder mainly outputs linear motion and force. The flying wing compartment 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 flying wing compartment hydraulic cylinder, plunger flying wing compartment hydraulic cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger flying wing compartment hydraulic cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.
flying wing compartment hydraulic cylinder use should try to avoid sealing belt into the flying wing compartment hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the flying wing compartment hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the flying wing compartment hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.
Factors that should be considered when selecting the oil seal in the flying wing compartment hydraulic cylinder: some specific factors should be taken into account when selecting the oil seal in the flying wing compartment hydraulic cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: flying wing compartment hydraulic cylinder diameter, piston rod diameter, piston rod and piston groove size, flying wing compartment hydraulic cylinder working pressure, flying wing compartment hydraulic cylinder movement speed, hydraulic system oil temperature and flying wing compartment hydraulic cylinder working environment.
The daily inspection of the flying wing compartment hydraulic cylinder includes: checking the connection of the flying wing compartment hydraulic cylinder and the pipe joint for leaks. Check the flying wing compartment hydraulic cylinder rod for leaks. Check the flying wing compartment hydraulic cylinder connection for leaks. When the flying wing compartment hydraulic cylinder moves, the work is normal and smooth. Whether the flying wing compartment hydraulic cylinder has internal leakage.
How to produce good quality hydraulic cylinder?
According to the principle of quality control, it is considered from five aspects: people, machine, material, method and environment. 1, People, refers to the processing and assembly operators. Their skills, professional qualifications, literacy should meet the requirements of production. For example, do your machining workers have the required grade certificate? Do your welders have welding certificate? 2, Machine, refers to your production equipment. Production cylinders have requirements for processing equipment. For example, the piston rod requires chrome grinding. Can your equipment meet the need? 3, Material. The material you use should meet the quality requirements. For example, the sealing ring of PARK and domestic goods is different. Material is also very important. 4. Method refers to the process method. Do your processing and assembly processes meet the requirements? 5, Environment. The environment shall be neat and orderly, clean and hygienic. It is especially important for the hydraulic cylinder production enterprise environment. Can your assembly shop site be clean and dust-free? Quality inspection is also a focus of control. Products should do pressure test, leakage test. The test pressure should reach 1.25 times the design pressure. If you can't maintain pressure, what about quality? You may not be able to do the whole process of cylinder production, you can take the method of OEM. Taking advantage of the strengths of specialized manufacturers, you contract out what you need and then assemble it yourself. But the principle of quality control is the same.
Why does excavator cylinder oil leak?
Under normal circumstances, the leakage of hydraulic cylinders is divided into internal leakage and external leakage. The external leakage is generally due to damage to the oil seal at the extended end of the piston rod and needs to be replaced. Internal leakage is generally because the oil seal on the piston is damaged, you can try to replace the oil seal here, if the replacement will also leak, then check whether there is damage to the inner wall of the cylinder.
