New Zealand trailer hydraulic cylinder

(New Zealand trailer hydraulic cylinder,produced by Hebei Hengyu company)

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

Introduction to trailer hydraulic cylinder:

The viscosity of the working oil used in the trailer hydraulic cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

The material, shape and compression of the trailer hydraulic cylinder seal have a great impact on the service life and work efficiency of the trailer hydraulic cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

The internal leakage of the trailer hydraulic cylinder is an important indicator to measure the quality of the trailer hydraulic cylinder: the internal leakage of the trailer hydraulic cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the trailer hydraulic cylinder, so that the trailer hydraulic cylinder can not accurately and stably stop in a certain position of the trailer hydraulic cylinder, so it is one of the main indicators of the trailer hydraulic cylinder.

How to repair the trailer hydraulic cylinder body when it is damaged: When the trailer hydraulic cylinder has trace deformation and shallow tensile marks, the trailer hydraulic cylinder is repaired by strong honing process. The heavy honing process can repair trailer hydraulic cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the trailer hydraulic cylinder can meet the technical requirements.

Answers to some questions about trailer hydraulic cylinder:

How to deal with hydraulic cylinder inner wall rag, local wear serious or corrosion?
It can be reparied if the inner wall of the hydraulic cylinder is frayed, local wear or corrosion. We can use the inner wall cold melting copper technology, it has the following advantages: first, the temperature is low, the operating temperature is less than 180 degrees, and the heat affected zone is small. Second: high hardness is up to Brinell hardness 280, wear resistance and anti-corrosion. Third: the process is mature, some large coal mills have been repaired with this method and the effect is remarkable.

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)
