Congo metallurgical cylinder

(Congo metallurgical cylinder,produced by Hebei Hengyu company)

metallurgical cylinder are widely used in Congo,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed metallurgical cylinder for customers from Congo.

Introduction to metallurgical cylinder:

The difference between the plunger metallurgical cylinder and the piston metallurgical cylinder is that the piston in the metallurgical cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type metallurgical cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

metallurgical 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 metallurgical 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 ' metallurgical 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 metallurgical cylinder and the hydraulic motor are devices that convert the pressure energy of the liquid into mechanical energy and output it. The metallurgical cylinder mainly outputs linear motion and force. The metallurgical 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 metallurgical cylinder, plunger metallurgical cylinder is mainly used for: machinery, such as excavators; Scientific research, such as university structure laboratory. The plunger metallurgical cylinder is used for pressure testing machines, such as Jinan test, and the test machine is used for material testing.

The metallurgical cylinder is not the same as the metallurgical cylinder, because the pressure of the pneumatic system is generally within the range of 0.2-1.0Mpa, the metallurgical cylinder can not be used as a high-power power component, but the metallurgical cylinder can be used as a relatively large power component, or the metallurgical cylinder system can be used.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the metallurgical cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

Answers to some questions about metallurgical cylinder:

What brand of hydraulic cylinder seal ring is best?
Depending on the specific product, the world famous seal brands are NOK, CFW, PARKER, TSS, WKF, DINGZING DZ, ASTON, HALLITE, TECNOLAN and so on.

How to deal with hydraulic cylinder inner wall rag, local wear serious or corrosion?
It can be reparied if the inner wall of the hydraulic cylinder is frayed, local wear or corrosion. We can use the inner wall cold melting copper technology, it has the following advantages: first, the temperature is low, the operating temperature is less than 180 degrees, and the heat affected zone is small. Second: high hardness is up to Brinell hardness 280, wear resistance and anti-corrosion. Third: the process is mature, some large coal mills have been repaired with this method and the effect is remarkable.
