(Britain discharge door cylinder,produced by Hengyu Hydraulic Cylinder Factory）

discharge door cylinder are widely used in Britain，because of long service life，smooth movement，high work efficiency.So our company has designed discharge door cylinder for customers from Britain.

Introduction to discharge door cylinder:

Before the discharge door cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

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

When the discharge door cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the discharge door cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil discharge door cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical discharge door cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the discharge door cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

When installing the discharge door cylinder pipe, the pipe should be cleaned after installation, and should not pass through the discharge door cylinder block, and the by-pass pipe must be installed in front of the oil port of the discharge door cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the discharge door cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the discharge door cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

Answers to some questions about discharge door cylinder:

What is the cylinder with rod cavity, what is the rodless cavity.
The rod cavity is the end of the piston rod, the rodless cavity is the end without the piston rod.

What is a constant velocity cylinder? What is the difference between hydraulic cylinder and constant velocity cylinder?
The constant speed cylinder should be the same as the speed of the piston rod extension and withdrawal cylinder is called the constant speed cylinder. The difference between it and the ordinary hydraulic cylinder is that the ordinary hydraulic cylinder only has a piston rod extended out, and the general extension speed is slow and the recovery speed is fast, because of the relationship between the effective area. Effective area of piston chamber > Effective area of piston rod chamber. The effective area on both sides of the constant speed cylinder is the same, because there are piston rods sticking out at both ends. The application of constant speed cylinder is most common in grinding machines.
