Dominica rolling mill cylinder

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

rolling mill cylinder are widely used in Dominica,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed rolling mill cylinder for customers from Dominica.

Introduction to rolling mill cylinder:

The internal leakage of the rolling mill cylinder is an important indicator to measure the quality of the rolling mill cylinder: the internal leakage of the rolling mill cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the rolling mill cylinder, so that the rolling mill cylinder can not accurately and stably stop in a certain position of the rolling mill cylinder, so it is one of the main indicators of the rolling mill cylinder.

The rolling mill cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the rolling mill cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the rolling mill cylinder wall due to the stiffness and the weight of the parts, causing scars.

The rolling mill cylinder pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.

The difference between the plunger rolling mill cylinder and the piston rolling mill cylinder is that the piston in the rolling mill cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type rolling mill cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

Answers to some questions about rolling mill cylinder:

What is the difference between hydraulic piston cylinder and plunger cylinder?
The force surface of the piston cylinder is a rod cavity and a rodless cavity, and the force surface of the plunger cylinder is the plunger, the spring return single-acting piston cylinder can also rely on the external force of the spring to achieve return, the double-acting piston cylinder can produce tension, and the plunger cylinder only produces thrust without tension.

What is the material of the lift cylinder?
The cylinder is composed of many parts. The cylinder also contains the seal and the installation port at both ends, the material of these two parts is not easy to determine if there is no physical object. The cylinder body is generally 20 steel, 45 steel, 27SiMn and other materials, and the piston rod is generally 40Cr, 45 steel and other materials.
