Methods to avoid hydraulic cylinder fluid contamination

Methods to avoid hydraulic cylinder fluid contamination

 Avoid hydraulic cylinder fluid contamination, refers to the mixing of air, moisture and curing material from the outside world, etc., in use, such as mixing rusted metal powder, it destroys the sealing material, paint and other crumbly material. Pollution of the oil, will exacerbate the wear and tear between the relative moving parts in the components, resulting in the blockage of throttle holes or slide valve movement amplitude jamming, so that the components can not work properly.

      According to statistics, more than 75% of the system failure is due to oil contamination. Therefore, measures need to be taken to avoid or reduce oil pollution, the main methods are:

      1, before the installation of pipelines, castings and other cleaning, hydraulic cylinder system to be cleaned after the completion of assembly;

      2, the assembly of the components, prohibit the use of fabrics with fibers (such as cotton yarn) wipe;

      3, the oil tank should be reasonably sealed, through the atmosphere should be set at the air filter;

      4, the seal should be secure, prohibit the use of oil-resistant seals and hoses;

      5、Reasonable selection of the type of filter and installation location. The system should be configured according to the need for coarse and fine oil filter. The oil filter should be frequently checked for use, and should be replaced in time if it is found to be damaged;

      6, regular replacement of oil, generally more than 10,000 hours of cumulative work, the oil should be changed. If you continue to use, the oil will lose lubricating properties, and may show acidic, thus causing corrosion of the metal parts of the hydraulic cylinder system, etc.. If intermittent use, according to the specific circumstances of every six months or a year to change the oil.
