(Switzerland metallurgical cylinder,produced by Hebei Hengyu company）

metallurgical cylinder are widely used in Switzerland，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed metallurgical cylinder for customers from Switzerland.

Introduction to metallurgical cylinder:

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.

When the metallurgical cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the metallurgical cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

metallurgical cylinder piston rod material selection and technical requirements: (I), because there is no special requirements, so use 45 steel as the piston rod material, the design of the piston rod only withstand pressure stress, so no modulation processing; (ii) The coaxial tolerance of the shaft journal and the outer circle of the mounting piston is not greater than 0.01mm, so as to ensure the coaxial degree of the outer circle of the piston rod and the outer circle of the piston, and avoid the stuck phenomenon of the piston and the metallurgical cylinder, the piston rod and the guide. The vertical tolerance between the end face of the mounting piston and the axis of the piston rod is not more than 0.04mm/100mm to ensure that the piston installation does not produce skew; (iii) The outer circle of the piston rod should pay attention to the roughness; (iv) Because it is operated under low load conditions, surface treatment is omitted.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the metallurgical cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

Answers to some questions about metallurgical cylinder:

How to calculate the tonnage of hydraulic cylinder? The tonnage of the cylinder refers to the output force of the cylinder under rated working pressure: 1, for single rod piston hydraulic cylinder, it can be calculated by the area of the circle corresponding to the inner diameter of the cylinder A (square centimeter), and the rated working pressure of the system p (mpa), the value is equal to 10pA kg force, and the ton is 0.01pA. 2, for the double rod piston hydraulic cylinder, with A(square centimeter) to indicate the cylinder cylinder diameter and piston rod outer diameter defined by the ring area, with p (mpa) to indicate the rated working pressure of the system, the output force of the cylinder is 0.01pA ton force.

What hydraulic oil does servo cylinder generally use?
The medium used by the cylinder generally depends on the working condition of the use, including pressure, installation environment, sealing material, etc. I think the first thing to consider is the impact of the sealing material. Mineral oil is a good choice if it is not too fire-resistant or used in a high temperature environment. 1, servo cylinder features: closed-loop servo control, control accuracy of 0.01mm; Precise control of thrust, increase pressure sensor, control accuracy up to 1%; It is easy to connect with PLC and other control systems to achieve high precision motion control. Low noise, energy saving, clean, high rigidity, impact resistance, long life, simple operation and maintenance. 2, the servo cylinder can be fault-free in harsh environments, and the protection level can reach IP66.
