(Uzbekistan metallurgical cylinder,produced by Hengyu Hydraulic Co., Ltd）

metallurgical cylinder are widely used in Uzbekistan，because of no need for deceleration device，long service life，smooth movement.So our company has designed metallurgical cylinder for customers from Uzbekistan.

Introduction to metallurgical cylinder:

The method of sleeve metallurgical 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 metallurgical cylinder can be significantly improved by rolling in the finishing of the inner holes of the metallurgical cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

metallurgical cylinder buffer valve inspection and maintenance: For the valve buffer metallurgical cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

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.

In order to ensure the service life of the metallurgical cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the metallurgical cylinder, causing damage to the seal and causing leakage in the metallurgical cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

Answers to some questions about metallurgical cylinder:

Cylinder la-50-70st What does that mean?
Full model should be CX-LA-50-70ST, thin block cylinder, radial mounting, bore 50, stroke 70.

What is hydraulic cylinder internal leakage and external leakage?
The internal leakage of the hydraulic cylinder refers to the leakage of the piston head seal of the double-acting cylinder, and the leakage occurs inside the cylinder; The external leakage refers to the leakage phenomenon between the cylinder head (or cylinder guide sleeve) and the plunger rod (or piston rod) and the seal between the guide sleeve and the cylinder block, and the oil in the hydraulic cylinder leaks to the outside.
