Nepal hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder
(Nepal stroke adjustable cylinder,produced by Hebei Hengyu company）
stroke adjustable cylinder are widely used in Nepal，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed stroke adjustable cylinder for customers from Nepal.
The stroke adjustable cylinder is not the same as the stroke adjustable cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the stroke adjustable cylinder can not be used as a high-power power component, but the stroke adjustable cylinder can be used as a relatively large power component, or the stroke adjustable cylinder system can be used.
Most of the failure of the stroke adjustable cylinder is because there is a foreign body in the stroke adjustable cylinder into the failure of the stroke adjustable cylinder, the most problematic is that it is difficult to determine when the foreign body is into the stroke adjustable cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.
The stroke adjustable cylinder is mainly composed of body, piston, piston rod, stroke adjustable cylinder head, stroke adjustable cylinder bottom, piston rod head and related auxiliary devices. The piston divides the stroke adjustable cylinder into two chambers, and moves reciprocally in the stroke adjustable 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 stroke adjustable cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the stroke adjustable 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 stroke adjustable 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 stroke adjustable cylinder bottom and the stroke adjustable cylinder head is serious, so the buffer deceleration should be set at both ends of the stroke adjustable cylinder The working medium of the stroke adjustable cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; stroke adjustable 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 stroke adjustable cylinder: The buffer structure of the stroke adjustable cylinder is to prevent the piston from colliding with the stroke adjustable cylinder head at the end of the stroke.
The meaning of the stroke adjustable cylinder model marked by the stroke adjustable cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the stroke adjustable cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the stroke adjustable cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.
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.
What is the material of the hydraulic cylinder slider?
Three parts of the hydraulic cylinder are essential, which are: cylinder - cylinder head assembly, piston - piston rod assembly, and sealing device. When you say slider, you mean piston. - Piston rod. Piston materials commonly used gray cast iron, wear-resistant cast iron, aluminum alloy (assembled), etc., can also be used 35 and 45 steel (integral). The piston rod is generally made of 35 and 45 steel. When the impact vibration is large, alloy steel such as 55 steel or 40Cr is used.
