It is expensive to purchase a set of hydraulic system, and it costs a lot of money and material resources. However, in daily application, we do not know how to maintain our own hydraulic system, which results in the hydraulic system Oil motor The service life is simple and clear. There are countless examples of this kind. So how should we maintain our application Connecting rod free radial piston motor So. Please look down.

For the inspection and maintenance of seals, it is necessary to check whether there is scar and damage on the lip edge of the mouth shaped seals, and check the wear rate of the convex surface of the sealing components, and then judge whether the seals can be used. In addition, it is necessary to check whether the piston rod and the static seal ring of the piston rod are pinched. Once defects are found in the seals and guide support rings, the seals with the same structure and suitable for raw materials shall be removed and replaced according to the structural form of the seals of the hydraulic system being repaired, which can greatly reduce the thickness of the oil slick between the seals and the sealing surface and reduce the leakage of the seals.

Inspection and maintenance of cylinder liner The internal surface of the cylinder liner and the sealing of the piston rod of the hydraulic system are the key factors that cause the internal leakage of the hydraulic system. If there is a longitudinal pull mark in the cylinder liner, even if the piston rod of the core is removed or replaced, the sealing is good.

Inspection and maintenance of piston rod and guide sleeve The relative speed pair of piston rod and guide sleeve is the key factor causing exposure. If the plated layer on the piston rod surface falls off due to damage or causes longitudinal pull marks, it will immediately cause the invalidity of the seals. Therefore, it is critical to check whether the surface roughness of the piston rod and the dimensional tolerance of personal behavior meet the technical standards. If the piston rod is bent, it should be straightened to meet the requirements or the surveying and mapping engineering should be carried out according to the commodities, so as to carry out production and manufacturing for technical professional manufacturers. If the surface coating of the piston rod is damaged, scratched or partially peeled off, the coating can be removed and the surface can be plated again for production processing
