(Pakistan metallurgical cylinder,produced by Hebei Hengyu company）

metallurgical cylinder are widely used in Pakistan，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed metallurgical cylinder for customers from Pakistan.

Introduction to metallurgical cylinder:

There are some honeycomb holes in the inner wall of the metallurgical cylinder, piston or piston rod surface. How is this formed? When we repair the metallurgical cylinder, we can see that there are some honeycomb holes on the inner wall of the metallurgical cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the metallurgical cylinder is targeted to prevent. Is very necessary.

The difference between the integral metallurgical cylinder and the split metallurgical cylinder: The integral metallurgical cylinder and the split metallurgical cylinder in the metallurgical cylinder are two different metallurgical cylinders, and they are very different. The whole metallurgical cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split metallurgical cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and metallurgical cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

metallurgical cylinder installation precautions: Before installing the metallurgical cylinder into the system, the parameters on the metallurgical cylinder label should be compared with the parameters when ordering. The base of the metallurgical cylinder must have sufficient stiffness, otherwise the metallurgical cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

The metallurgical cylinder is mainly composed of body, piston, piston rod, metallurgical cylinder head, metallurgical cylinder bottom, piston rod head and related auxiliary devices. The piston divides the metallurgical cylinder into two chambers, and moves reciprocally in the metallurgical cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the metallurgical cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the metallurgical cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the metallurgical cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the metallurgical cylinder bottom and the metallurgical cylinder head is serious, so the buffer deceleration should be set at both ends of the metallurgical cylinder The working medium of the metallurgical cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; metallurgical cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the metallurgical cylinder: The buffer structure of the metallurgical cylinder is to prevent the piston from colliding with the metallurgical cylinder head at the end of the stroke.

Answers to some questions about metallurgical cylinder:

What is the material of the lift cylinder?
The cylinder is composed of many parts. The cylinder also contains the seal and the installation port at both ends, the material of these two parts is not easy to determine if there is no physical object. The cylinder body is generally 20 steel, 45 steel, 27SiMn and other materials, and the piston rod is generally 40Cr, 45 steel and other materials.

How to set up the one-way cylinder hydraulic system?
Single acting oil cylinder, that is, an oil cylinder with an oil port, can use two three-way valves to control the cylinder action. The three oil ports are respectively connected to P (oil pump), A (oil cylinder), and T (oil tank). If the oil pump is to run continuously, an electromagnetic relief valve can be added. When the cylinder is not moving, the relief valve can unload the oil pump. You can also add a three-way four-way valve, the middle function is unloaded, two outlets: A connected to the fuel tank, B connected to the cylinder.
