Germany plunger type cylinder

(Germany plunger type cylinder,produced by Hengyu Hydraulic Co., Ltd)

plunger type cylinder are widely used in Germany,because of no need for deceleration device,smooth movement,excellent temperature resistance.So our company has designed plunger type cylinder for customers from Germany.

Introduction to plunger type cylinder:

The assembly work of the plunger type cylinder has a great impact on the quality of the plunger type cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

When the piston speed of the plunger type cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the plunger type cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

The internal leakage of the plunger type cylinder should be prevented when the plunger type cylinder is used. The internal leakage of plunger type cylinder includes the leakage caused by excessive wear of plunger type cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

If it is found that the plunger type cylinder lubrication is poor or the plunger type cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the plunger type cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the plunger type cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the plunger type cylinder center line. In this way, when the piston works in the plunger type cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the plunger type cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

Answers to some questions about plunger type cylinder:

Why is the hydraulic cylinder of the larger excavator arm upside down?
The weight of the excavating arm of a large excavator will be very heavy, and an oil cylinder has two cavities, one is a rod cavity, and the other is a rodless cavity. The lifting force of the excavator is the product of the ortho-projection area of the piston rod cavity by the oil pressure, so the strength of the rodless cavity is much greater than that of the rod cavity. And the parallel bars with the piston rod facing down are also conducive to assembly and future maintenance. So a large excavator has to keep the cylinder facing down.

Slide weight 35 kg exit stroke 55mm, is it suitable to use 40 cylinder diameter cylinder?
The maximum output force of the 40-bore hydraulic cylinder can reach 2 tons, and whether it can be used depends on the use scenario. In addition, the problem of mechanism stuck has nothing to do with the size of the power source, and reasonable structural design and good machining and assembly accuracy are the key.
