(Norway stacker cylinder,produced by Hengyu Hydraulic Co., Ltd）

stacker cylinder are widely used in Norway，because of long service life，no transmission clearance，powerful torque.So our company has designed stacker cylinder for customers from Norway.

Introduction to stacker cylinder:

The meaning of the stacker cylinder model marked by the stacker cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the stacker cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the stacker cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

The coordination of the sliding parts of the stacker cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

Piston stacker cylinder is widely used in hydraulic transmission. When the stacker cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the stacker cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the stacker cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

When the stacker 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 stacker cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the stacker cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the stacker cylinder can meet the requirements by grinding. However, the life and reliability of this repair stacker cylinder are not high.

Answers to some questions about stacker cylinder:

How to calculate hydraulic cylinder thrust?
Cylinder diameter = piston diameter =200MM Piston area =π (200/2) square =3140 square mm =31.4 square cm 25MPA=250KG/ square cm Maximum thrust = pressure * Piston area =250 *31.4 =7850KG=78500 Newtons This is the maximum thrust. The formula can be derived from the calculation formula.

How to change the seal ring of lift oil cylinder of forklift truck?
Remove the cylinder, put it on the vise, first screw off the big nut plug on the head, and then pull out the guide sleeve, you can directly pull out the core of the cylinder, if it is to change the seal of the cylinder head, the core does not need to be pulled out, if it is to change the seal inside, pull it out and see the oil seal, remove it and replace it, there are three seals of the cylinder head, the inner seal, The outer seal, dustproof, it is best to replace them all together, and be sure to keep them clean when changing, and you can lubricate them with clean hydraulic oil.
