Brazil hydraulic cylinder,hydraulic gate cylinder manufacturer,hydraulic gate cylinder

(Brazil hydraulic gate cylinder,produced by Hebei Hengyu company）

hydraulic gate cylinder are widely used in Brazil，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed hydraulic gate cylinder for customers from Brazil.

Introduction to hydraulic gate cylinder:

Protection of the hydraulic gate cylinder surface: During the dismantling process, safety protection should be carried out on the hydraulic gate cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the hydraulic gate cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the hydraulic gate cylinder should be cleaned up in time.

When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the hydraulic gate cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.

The method of sleeve hydraulic gate cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the hydraulic gate cylinder can be significantly improved by rolling in the finishing of the inner holes of the hydraulic gate cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

When purchasing the hydraulic gate cylinder, try to clarify the following parameters of the hydraulic gate cylinder: A. hydraulic gate cylinder diameter, rod diameter, stroke; B. Working pressure or hydraulic gate cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right hydraulic gate cylinder type can be found accurately and quickly.

Answers to some questions about hydraulic gate cylinder:

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.

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.
