accumulator hydraulic cylinder are widely used in Libya，because of long service life，smooth movement，high work efficiency.So our company has designed accumulator hydraulic cylinder for customers from Libya.

Introduction to accumulator hydraulic cylinder:

Under normal circumstances, the accumulator hydraulic 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 accumulator hydraulic cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the accumulator hydraulic cylinder and the end cover, the piston and the piston rod, the piston and the accumulator hydraulic 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 accumulator hydraulic 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 accumulator hydraulic 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.

Piston accumulator hydraulic cylinder is widely used in hydraulic transmission. When the accumulator hydraulic cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the accumulator hydraulic 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 accumulator hydraulic 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 accumulator hydraulic cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the accumulator hydraulic cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.

Answers to some questions about accumulator hydraulic cylinder:

How to make 4 cylinders balance lifting weight at the same time?
The cost of the synchronous valve is lower, 4 cylinders need 3 synchronous valves, to be precise you can use a synchronous motor, but it is more expensive. There is another way, that is to install a throttle valve in each cylinder, respectively adjust the speed of the cylinder.

Why should the piston rod of the hydraulic cylinder be so precise? If you hope the cylinder has a long service cycle, then all parts need to be high-precision, not only the piston rod, but also the cylinder, the sealing groove, the surface roughness, the cylinder looks very simple. Any hydraulic factory can produce the cylinder, but the good cylinder is difficult to produce.
