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

Introduction to crane support cylinder:

The crane support cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the crane support cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the crane support cylinder wall due to the stiffness and the weight of the parts, causing scars.

Because of the slightly complex structure of the buffer crane support cylinder, sometimes there will be problems, such as when the crane support cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

When the crane support 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 crane support 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.

When the oil pressure of the crane support cylinder inlet is too low to reach the specified value, the leakage situation of the relevant oil system should be checked and the leakage should be eliminated; Check the piston and piston rod seal ring for damage, aging, loose and other phenomena; Check whether the hydraulic pump and pressure valve are faulty.

Answers to some questions about crane support cylinder:

A hydraulic system functions three cylinders to maintain pressure, what components need to be used?
Two way cartridge valve can be selected for control. Two way cartridge valve advantages: 1) flow capacity is large, especially suitable for large flow occasions. 2) The spool has sensitive action and strong anti-clogging ability. 3) Good sealing, small leakage, oil flow through the valve pressure loss is small. 4) Simple structure, easy to standardize.

How to distinguish high pressure cylinder and low pressure cylinder?
There is no special definition of the cylinder, the so-called pressure classification refers to the pump low pressure (code L) container 0.1MPa ≤p < 1.6MPa; Medium pressure (code M) container 1.6MPa ≤p < 10.0MPa; High pressure (code H) vessel 10 MPa≤p < 100 MPa; Ultra-high pressure (code U) container p≥100MPa. (1MPa=9.8Kg)
