(Czech Republic electromagnetic induction cylinder,produced by Hengyu Group）
electromagnetic induction cylinder are widely used in Czech Republic，because of simple structure and reliable operation，powerful torque，clever hydraulic energy conversion.So our company has designed electromagnetic induction cylinder for customers from Czech Republic.
The cavitation of the electromagnetic induction cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the electromagnetic induction cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.
The pressure of the sliding surface of the electromagnetic induction cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the electromagnetic induction cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.
Most of the failure of the electromagnetic induction cylinder is because there is a foreign body in the electromagnetic induction cylinder into the failure of the electromagnetic induction cylinder, the most problematic is that it is difficult to determine when the foreign body is into the electromagnetic induction cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.
There are some honeycomb holes in the inner wall of the electromagnetic induction cylinder, piston or piston rod surface. How is this formed? When we repair the electromagnetic induction cylinder, we can see that there are some honeycomb holes on the inner wall of the electromagnetic induction cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the electromagnetic induction cylinder is targeted to prevent. Is very necessary.
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.
Design a hydraulic cylinder, the inner diameter of the cylinder is 100mm, what size of piston rod is best used?
This involves how much speed ratio you need, that is, the area ratio of the rod cavity and the rodless cavity, if the weight is relatively large, it is recommended that the speed ratio choose 2, that is, the piston rod diameter choose 70mm, under normal circumstances, the speed ratio choose 1.46, the piston rod diameter choose 55mm. Of course, there are many factors that affect the diameter of the piston rod, such as stroke, stroke is too long, in order to stabilize the work of the hydraulic cylinder, its diameter also needs to choose a relatively large, sometimes even non-standard products, need to choose according to the actual situation.
