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

Introduction to supporting cylinder:

When the supporting cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the supporting cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the supporting cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the supporting cylinder can meet the requirements by grinding. However, the life and reliability of this repair supporting cylinder are not high.

The difference between the plunger supporting cylinder and the piston supporting cylinder is that the piston in the supporting 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 supporting cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

When the oil pressure of the supporting cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.

When the supporting cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the supporting cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil supporting cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical supporting cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the supporting cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

Answers to some questions about supporting cylinder:

What factors does the movement speed of the cylinder in the hydraulic system depend on?
The hydraulic system should be the piston movement in the cylinder, and the speed should also be the speed of the piston, according to the piston speed formula: v=4qm/pai*(D^2-d^2) where q is the flow rate of the input hydraulic cylinder, m is the volumetric efficiency of the hydraulic cylinder, D, d is the diameter of the piston and piston rod, because other factors are determined, the movement speed of the cylinder depends on the flow rate.

What is a constant velocity cylinder? What is the difference between hydraulic cylinder and constant velocity cylinder?
The constant speed cylinder should be the same as the speed of the piston rod extension and withdrawal cylinder is called the constant speed cylinder. The difference between it and the ordinary hydraulic cylinder is that the ordinary hydraulic cylinder only has a piston rod extended out, and the general extension speed is slow and the recovery speed is fast, because of the relationship between the effective area. Effective area of piston chamber > Effective area of piston rod chamber. The effective area on both sides of the constant speed cylinder is the same, because there are piston rods sticking out at both ends. The application of constant speed cylinder is most common in grinding machines.
