Nepal hydraulic cylinder,servo hydraulic cylinder manufacturer,servo hydraulic cylinder
(Nepal servo hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd）
servo hydraulic cylinder are widely used in Nepal，because of long service life，smooth movement，high work efficiency.So our company has designed servo hydraulic cylinder for customers from Nepal.
The daily inspection of the servo hydraulic cylinder includes: checking the connection of the servo hydraulic cylinder and the pipe joint for leaks. Check the servo hydraulic cylinder rod for leaks. Check the servo hydraulic cylinder connection for leaks. When the servo hydraulic cylinder moves, the work is normal and smooth. Whether the servo hydraulic cylinder has internal leakage.
The servo hydraulic cylinder is not the same as the servo hydraulic cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the servo hydraulic cylinder can not be used as a high-power power component, but the servo hydraulic cylinder can be used as a relatively large power component, or the servo hydraulic cylinder system can be used.
The quality of the servo hydraulic cylinder can not be ignored in the purchase of the servo hydraulic cylinder. The servo hydraulic cylinder is the main component of the servo hydraulic cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. servo hydraulic cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of servo hydraulic cylinder is deep hole processing, which has always troubled the processing personnel.
Causes and countermeasures of oil servo hydraulic cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the servo hydraulic cylinder will lead to premature wear of the piston seal, replace the piston seal; If the servo hydraulic cylinder is visibly scarred, the servo hydraulic cylinder must be replaced. It can be pressurized at one end of the servo hydraulic cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most servo hydraulic cylinder piston drift may not come from the servo hydraulic cylinder, the above method to determine the servo hydraulic cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
How to make 4 cylinders balance lifting weight at the same time?
The cost of the synchronous valve is lower, 4 cylinders need 3 synchronous valves, to be precise you can use a synchronous motor, but it is more expensive. There is another way, that is to install a throttle valve in each cylinder, respectively adjust the speed of the cylinder.
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.
