Estonia hydraulic cylinder,rolling mill cylinder manufacturer,rolling mill cylinder

(Estonia rolling mill cylinder,produced by Hebei Hengyu company）

rolling mill cylinder are widely used in Estonia，because of excellent fatigue and impact resistance，smooth movement，high work efficiency.So our company has designed rolling mill cylinder for customers from Estonia.

Introduction to rolling mill cylinder:

Protection of the rolling mill cylinder surface: During the dismantling process, safety protection should be carried out on the rolling mill cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the rolling mill 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 rolling mill cylinder should be cleaned up in time.

The material, shape and compression of the rolling mill cylinder seal have a great impact on the service life and work efficiency of the rolling mill cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

rolling mill cylinder and hydraulic station selection: Select the type and structure of the rolling mill cylinder according to the operation requirements of the main engine. According to the external load force borne by the rolling mill cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the rolling mill cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the rolling mill cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the rolling mill cylinder, the diameter of the piston and the piston rod.

The scar on the sliding surface of the rolling mill cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the rolling mill cylinder wall. Therefore, before installation, these scars must be fully repaired.

Answers to some questions about rolling mill cylinder:

How to distinguish the size of hydraulic cylinder cavity?
The hydraulic cylinder has a rod cavity and a rodless cavity. The rod cavity is the cavity that the piston rod extends out. The rod cavity is of course small due to the existence of the piston rod. That's just relative.

Why the lifting cylinder falling by itself?
May be there is a pressure relief point. Check and repair the following parts: whether there is oil leakage in the transparent pipe at the top of the cylinder: the cylinder oil seal is broken, and the cylinder and oil seal need to be replaced; No: The multiway valve has pressure relief and needs to be repaired. Maintenance in accordance with routine maintenance items can reduce mechanical failures: 1. Check whether the thermostat works normally. 2, check the transmission shift work is normal. 3. Check the tightness of the fan belt. 4, check whether the diesel tank oil inlet filter is blocked or damaged, and clean or replace the filter. 5. Check and adjust the valve clearance.
