(Bulgaria single rack cylinder,produced by Hengyu Hydraulic Co., Ltd)

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

Introduction to single rack cylinder:

The piston rod of the single rack cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

There are some honeycomb holes in the inner wall of the single rack cylinder, piston or piston rod surface. How is this formed? When we repair the single rack cylinder, we can see that there are some honeycomb holes on the inner wall of the single rack cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the single rack cylinder is targeted to prevent. Is very necessary.

How to repair the single rack cylinder body when it is damaged: When the single rack cylinder has trace deformation and shallow tensile marks, the single rack cylinder is repaired by strong honing process. The heavy honing process can repair single rack cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the single rack cylinder can meet the technical requirements.

single rack cylinder to reasonable use of hydraulic oil: strict hydraulic oil selection off. Hydraulic oil is selected in strict accordance with oil standards. The selection of good quality hydraulic oil can effectively prevent bubbles in the working process of the hydraulic system. When choosing the oil, it should be selected according to the lowest temperature in different regions, and fill the hydraulic oil according to the dipstick standard, and at the same time, it should also keep the hydraulic system clean (when filling the hydraulic oil, it should prevent the water and other impurities into it), and often check the oil quality, oil level and oil color of the hydraulic oil. If blisters and bubbles are found in the hydraulic oil. When the oil becomes milky white, the source of the air in the oil should be carefully found and eliminated in time.

Answers to some questions about single rack cylinder:

Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.

How to remove the air in hydraulic cylinder?
Connected the cylinder to the system, and reciprocating move with full stroke several times, then the air can be eliminated . There is also a clunky method as follows: first remove the rod cavity oil pipe, connect the rodless cavity oil circuit to extend all the cylinders, and then remove the rodless cavity oil pipe, connect the rod cavity oil pipe and withdraw all the cylinders, and then connect the rodless cavity oil pipe, so that there is no air in the cylinder.
