(Luxembourg ejector cylinder,produced by Hengyu Group）

ejector cylinder are widely used in Luxembourg，because of no transmission clearance，simple structure and reliable operation，excellent temperature resistance.So our company has designed ejector cylinder for customers from Luxembourg.

Introduction to ejector cylinder:

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

Improve the service life of the ejector cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the ejector cylinder (such as the ejector cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the ejector cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the ejector cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single ejector cylinder exhaust.

The advantages and disadvantages of the ejector cylinder: the surface of the ejector cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the ejector cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

When the ejector 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 ejector cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil ejector cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical ejector cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the ejector 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 ejector cylinder:

For a cylinder with a piston diameter of 100mm and a system pressure of 10MPa, what is the thrust?
Thrust is 7850 kg. Piston area A= πR^2=7850 square mm =78.5 square cm 10MPa = 100kg/cm^2 "^2" is square F = A x P =78.5 x 100=7850 kg.

How to calculate the tonnage of the hydraulic press? Example: The input cylinder pressure is 5Mpa, the end area of the cylinder piston is 100mm, and how much is the thrust tonnage?
F=P*S=5*10^6*3.14*(1/20)^2=39250N.
