Norway steel mill cylinder

(Norway steel mill cylinder,produced by Hengyu Hydraulic Cylinder Factory)

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

Introduction to steel mill cylinder:

After chrome plating of the piston rod of the steel mill cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

The steel mill cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the steel mill cylinder, bite. Elimination method: When installing the steel mill cylinder, ensure that the axis position of the steel mill cylinder is consistent with the direction of movement; Make the load borne by the steel mill cylinder as far as possible through the steel mill cylinder axis, to avoid the phenomenon of eccentricity.

In use, the steel mill cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the steel mill cylinder.

The steel mill cylinder should be vented: when the steel mill cylinder is installed or parked for a long time to work again, the air will penetrate into the steel mill cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the steel mill cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the steel mill cylinder, the oil is best entered and discharged from the highest point of the steel mill cylinder. steel mill cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Answers to some questions about steel mill cylinder:

How to calculate multistage cylinder volume?
When the multi-stage cylinder is extended, the largest cylinder is extended first, and when the largest cylinder stroke is completed, the second largest cylinder is extended again, the second largest cylinder stroke is completed, the third largest cylinder is extended again... Therefore, the cylinder extension length is less than the stroke of the largest cylinder, and the volume is the extension length times the inner hole area of the largest cylinder. The cylinder extension length is greater than the maximum cylinder stroke and less than (the largest cylinder stroke + the second largest cylinder stroke), and the volume is the largest cylinder stroke times the internal hole area of the largest cylinder + (the extension length - the largest cylinder stroke) times the second largest cylinder.

Classification and application of cylinders.
Hydraulic cylinder is divided into single acting hydraulic cylinder, double acting cylinder, combined hydraulic cylinder, swing hydraulic cylinder. Single acting cylinder is divided into plunger type hydraulic cylinder, single piston rod hydraulic cylinder, double piston rod hydraulic cylinder, telescopic hydraulic cylinder. Plunger type hydraulic cylinder: the plunger moves only in one direction, and the return stroke is to push the plunger back using its own weight or load. Single piston rod hydraulic cylinder: The piston moves only in one direction, and the return stroke is to push the plunger back using dead weight or load. Double piston rod hydraulic cylinder: both sides of the piston are equipped with piston rods, and pressure oil can only be supplied to one side of the piston. The return stroke usually uses spring force, gravity or external force. Telescopic hydraulic cylinder: It obtains long stroke with short cylinder. The hydraulic oil is pushed out from large to small section by section, and the external force is reduced from small to large.
