UAE hydraulic cylinder,synchronous hydraulic cylinder manufacturer,synchronous hydraulic cylinder
(UAE synchronous hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）
synchronous hydraulic cylinder are widely used in UAE，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed synchronous hydraulic cylinder for customers from UAE.
The material of the sliding part of the synchronous hydraulic cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.
The body of the synchronous hydraulic cylinder on the processing process requirements: the body of the synchronous hydraulic cylinder is an important and essential part of the synchronous hydraulic cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the synchronous hydraulic cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.
The synchronous hydraulic cylinder is mainly composed of body, piston, piston rod, synchronous hydraulic cylinder head, synchronous hydraulic cylinder bottom, piston rod head and related auxiliary devices. The piston divides the synchronous hydraulic cylinder into two chambers, and moves reciprocally in the synchronous hydraulic cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the synchronous hydraulic cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the synchronous hydraulic cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the synchronous hydraulic cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the synchronous hydraulic cylinder bottom and the synchronous hydraulic cylinder head is serious, so the buffer deceleration should be set at both ends of the synchronous hydraulic cylinder The working medium of the synchronous hydraulic cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; synchronous hydraulic cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the synchronous hydraulic cylinder: The buffer structure of the synchronous hydraulic cylinder is to prevent the piston from colliding with the synchronous hydraulic cylinder head at the end of the stroke.
In use, the synchronous hydraulic cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the synchronous hydraulic cylinder.
What is the rated pressure of the general cylinder?
This depends on the model of the cylinder, 1. The rated pressure of the light tie rod cylinder is 7 series 7MPa and 14 series 14MPa. 2. Rated pressure of engineering cylinder 16MPa. 3. Rexroth type metallurgical cylinder rated pressure 250MPa.
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.
