Introduction to the structure of the hydraulic cylinder cylinder

With the rapid development of our country's economy, increasing of the application of metallurgical standard hydraulic cylinders, we are looking for customers increasing metallurgical standard hydraulic cylinders, production of metallurgical standard hydraulic cylinder manufacturers more and more, universal hydraulic pneumatic manufacturing co. , LTD is a professional manufacturer metallurgical standard hydraulic cylinders, hydraulic cylinder, its technical characteristics are as follows: metallurgical standard hydraulic cylinders, metallurgical standard hydraulic cylinder with resistance to high pressure, v-shaped combination sealing ring, sealing is reliable, simple structure, good abrasion resistance YX type polyurethane seal ring and wide application scope of YX type rubber sealing ring; , using polyurethane or nitrile rubber frameless type shield; With ChanXiangFang valve, cylinder head, cylinder tail as either a band gap slow scale hydraulic cylinder fast start with, and to make a deflated; , metallurgical standard hydraulic cylinder valve stem with removable dustproof seal structure, is advantageous for the on-site maintenance; Piston rod hard chromium plating with dustproof, anti-rust, anti-corrosion, wear-resistant characteristics. According to the law of flow continuity, into the liquid flow rate is equal to the flow of the hydraulic cylinder cylinder cross section and the product of the velocity, and cylinder liquid flow section is the effective area of piston, the average flow velocity is the rate of movement of the piston. The structure of the hydraulic cylinder cylinder basically can be divided into cylinder and cylinder head, piston and piston rod, sealing device, the buffer device and exhaust system five parts, the points mentioned below. Generally speaking, the structure of cylinder and the cylinder head with its materials used. Screwed connection structure is simple, convenient installation, but under the high pressure large load should be equipped with nut locking device. Half ring connection structure more complex, inconvenient installation, but work is more reliable. In addition, the piston and piston rod has made integral structure, but it is only applicable to small size. General made of wear resistant cast iron piston, piston rod, whether it's hollow or solid, are made of steel material. Gap seal, it relies on the tiny gap between moving parts to prevent leakage. In order to improve the sealing ability of the device, usually on the surface of the hydraulic cylinder piston cylinder making a few small circular groove, in order to increase the oil through the clearance of resistance. It has simple structure, small frictional resistance, resistant to high temperature, but the leak is big, high processing requirements, unable to restore the original after wear ability, only in small size, low pressure and high relative speed between the cylinder and piston to use.
