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

Introduction to metallurgical cylinder:

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.

In the case of serious wear on the inner surface of the metallurgical cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the metallurgical cylinder manufacturing process for replacement. The metallurgical cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

When using the metallurgical cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the metallurgical cylinder block. If the metallurgical cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the metallurgical cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the metallurgical cylinder, so that the working efficiency of the metallurgical cylinder is reduced.

When the metallurgical cylinder needs to be stored for a period of time, please follow the recommended methods: The metallurgical cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the metallurgical cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil metallurgical cylinder should not be in direct contact with water vapor for a long time. The metallurgical cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the metallurgical cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the metallurgical cylinder Before working, the metallurgical cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the metallurgical cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

Answers to some questions about metallurgical cylinder:

What are the problems that cause hydraulic cylinder shaking?
1, the oil supply is not smooth, the hydraulic oil filter is half blocked. 2. The oil level in the oil storage tank is lower than the minimum oil level. 3, there is air in the hydraulic system. 4, the supply oil pump is damaged or not working properly. 5, the hydraulic oil is not replaced for a long time.

What are the connection methods of the hydraulic cylinder? The connection modes of the cylinder and the actuator are earring connection, hinge shaft connection, thread connection, etc. The connection modes of tubing and cylinder are threaded connection, flange connection, etc.
