metallurgical cylinder are widely used in Belgium，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed metallurgical cylinder for customers from Belgium.

Introduction to metallurgical cylinder:

metallurgical cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the metallurgical cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the metallurgical cylinder. c. The metallurgical cylinder seal is extruded, if the O-ring is obviously extruded at the metallurgical cylinder seal, replace the metallurgical cylinder seal.

metallurgical cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards metallurgical cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the metallurgical cylinder guide is determined by the length of the stroke. Check the strength of metallurgical cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

When installing the metallurgical cylinder, the axial ends of the metallurgical cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the metallurgical cylinder, there is axial expansion. If the two ends of the metallurgical cylinder are fixed, all parts of the metallurgical cylinder will be deformed. When disassembling the metallurgical cylinder, it is strictly forbidden to hammer the metallurgical cylinder and the piston surface, such as the metallurgical cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

When the metallurgical cylinder is installed, the piston and the metallurgical cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the metallurgical cylinder head boss is easy to cause scars when it hits the inner surface of the metallurgical cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized metallurgical cylinders, only careful and careful operation can be avoided.

Answers to some questions about metallurgical cylinder:

What are the differences between hydraulic cylinder and pneumatic cylinder, what are their advantages and disadvantages?
Hydraulic Cylinder: small body and large force, constant speed and variable speed (easy to change), the adjustment of output is also convenient, and the degree of freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Pneumatic Cylinder: easy to control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, so it is more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion. Because the pressure used in the pneumatic system is generally in the range of 0.2-1.0Mpa, the cylinder is not suitable for high power component.

What is the cause of sound and vibration when the hydraulic cylinder is under load?
The main reason 1) may be that the load machinery has stuck phenomenon, and the resistance is large. 2) The hydraulic oil is not enough, or the filter is blocked by dirty things, and the oil is flooded. 3) There is a problem with the pump.
