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

Introduction to metallurgical cylinder:

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 should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the metallurgical cylinder, bite. Elimination method: When installing the metallurgical cylinder, ensure that the axis position of the metallurgical cylinder is consistent with the direction of movement; Make the load borne by the metallurgical cylinder as far as possible through the metallurgical cylinder axis, to avoid the phenomenon of eccentricity.

Piston metallurgical cylinder is widely used in hydraulic transmission. When the metallurgical cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the metallurgical cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the metallurgical cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

Protection of the metallurgical cylinder surface: During the dismantling process, safety protection should be carried out on the metallurgical cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the metallurgical 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 metallurgical cylinder should be cleaned up in time.

Answers to some questions about metallurgical cylinder:

Loader arm fell badly, how to know which oil cylinder is leaking?
No matter which cylinder leakage the arm will drop, it is best to replace the oil seal, even if one cylinder is good, it will not last long, and it will drop the arm, so the two cylinders should be replaced at once.

How long can a hydraulic cylinder work continuously?
If the maintenance is good, the service life can be extended a lot. The life of the cylinder is related to the structure of the cylinder, working pressure, stress state, hydraulic oil cleanliness, oil temperature control, maintenance and preventive measures. For example, the cylinder structure, the inner wall of the cylinder has quilting, rolling, chrome plating and other methods, the sealing parts have polyurethane rings, glay rings, metal sealing rings, etc., different combinations, the life difference is dozens of times. Metallurgical system is a typical cylinder application, in 24 hours of work, a year or more can not be shut down, in the middle of continuous work.
