Poland stacker cylinder

(Poland stacker cylinder,produced by Hengyu Hydraulic Cylinder Factory)

stacker cylinder are widely used in Poland,because of high work efficiency,long service life,smooth movement.So our company has designed stacker cylinder for customers from Poland.

Introduction to stacker cylinder:

When the stacker cylinder is customized, if there are high requirements for the quality of the stacker cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the stacker cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the stacker cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

The body of the stacker cylinder on the processing process requirements: the body of the stacker cylinder is an important and essential part of the stacker cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the stacker cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

Classification of stacker cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

After chrome plating of the piston rod of the stacker 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.

Answers to some questions about stacker cylinder:

Can the hydraulic oil in the cylinder return to the tank?
Yes, there is a way, for example, first remove the cylinder from the machine, and then connect the two pipes on the cylinder, so that the cylinder piston rod is completely retracted into the cylinder, at this time, the piston is with the bottom, and the rear chamber is almost no oil, and then screw off the joint at the end of the front chamber by the hydraulic station, and put it in an empty bucket. Finally, insert the gas pipe into the oil port of the rear chamber. Open the air source, and then the rod will run out, and you'll drain the hydraulic oil from the end of the rod, which requires a source of air on site.

PLC+ inverter + motor + pump + solenoid valve + cylinder combination, can control the accuracy of cylinder position?
In the case of extremely high accuracy requirements, you can not, please consider a few problems: 1, hydraulic oil can be compressed, it is elastic like a spring. Therefore, in the general hydraulic servo system, the valve control is far more accurate than the pump control. Because the valve can be installed very close to the hydraulic cylinder, or even installed on the hydraulic cylinder, but the pump must go through the tubing and then into the hydraulic cylinder, there is a long distance, which greatly reduces the rigidity of the system and increases the difficulty of control. 2, the quantitative pump is first of all leaking, and there is 10%-20% flow pulsation. Secondly, and more unfortunately, the leakage of the pump is related to the pressure and is non-linear.
