Czech Republic rolling mill cylinder

(Czech Republic rolling mill cylinder,produced by Hebei Hengyu company)

rolling mill cylinder are widely used in Czech Republic,because of clever hydraulic energy conversion,simple structure and reliable operation,excellent temperature resistance.So our company has designed rolling mill cylinder for customers from Czech Republic.

Introduction to rolling mill cylinder:

When the initial action of the rolling mill cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the rolling mill cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

When the rolling mill cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the rolling mill cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.

When the rolling mill cylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.

Regular maintenance of the rolling mill cylinder includes: regular tightening, rolling mill cylinder fastening screws and gland screws, rolling mill cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the rolling mill cylinder once a year. Clean regularly, the rolling mill cylinder is cleaned every other year, and the seals are replaced while cleaning.

Answers to some questions about rolling mill cylinder:

What material should be selected to seal the cylinder?
The choice of material for sealing is related to the working environment, strength, and medium of your equipment.

Are hydraulic cylinders divided into oil cylinders and water cylinders? What's the difference between the two types?
There are oil cylinders and water cylinders. The two cylinders are used in different environments. Oil cylinders are generally used in places where there is less demand for media, which is our most common hydraulic cylinders. Water cylinders are mainly used for large tonnage presses. Because the equipment is too large, the use of hydraulic oil will cause a relatively large waste. However, water is not pure water, there are oil-in-water emulsion and water-in-oil emulsion. Water has another benefit: it's flame retardant. It is especially suitable for some flammable and explosive occasions. Or with water glycol. The use of pure water is very little, mainly because the seal is not good and easy to rust.
