(Ireland hydraulic engineering cylinder,produced by Hebei Hengyu company）

hydraulic engineering cylinder are widely used in Ireland，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed hydraulic engineering cylinder for customers from Ireland.

Introduction to hydraulic engineering cylinder:

There are some honeycomb holes in the inner wall of the hydraulic engineering cylinder, piston or piston rod surface. How is this formed? When we repair the hydraulic engineering cylinder, we can see that there are some honeycomb holes on the inner wall of the hydraulic engineering cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the hydraulic engineering cylinder is targeted to prevent. Is very necessary.

The hydraulic engineering cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

Under normal circumstances, the hydraulic engineering cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the hydraulic engineering cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the hydraulic engineering cylinder and the end cover, the piston and the piston rod, the piston and the hydraulic engineering cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the hydraulic engineering cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the hydraulic engineering cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

Answers to some questions about hydraulic engineering cylinder:

How to achieve hydraulic cylinder self-locking?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil self-locking is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.

What are the four cylinders of the truck crane?
The four cylinders of the truck crane generally refer to the telescopic cylinder of the boom (to adjust the length of the boom), the variable amplitude cylinder of the boom (to adjust the elevation Angle of the boom), the horizontal telescopic cylinder of the support leg and the vertical cylinder of the support leg.
