However, according to our experience, these pollutants are traceable, hydraulic wrench system oil pollutants in the source of the main ways are the following:

First, the external invasion of pollutants

The intrusion of external contaminants is mainly gravel or dust in the atmosphere, usually through the hydraulic wrench tank stoma, cylinder seal shaft, pump and motor equiaxial invasion system. Mainly the use of the environment.

Second, internal pollutants

Hydraulic wrench components in the processing, assembly, commissioning, packaging, storage, transportation and installation of residual pollutants, of course, these processes are unavoidable, but can be reduced to the lowest, some special components in the assembly and commissioning need to Clean room or clean bench in the environment.

Third, the hydraulic wrench system generated pollutants

The particles produced in the process during the operation due to the wear of the components, the particles falling off from the castings, the pump, the valves and the metal particles falling off on the joints. The rust and peeling off the pipes are oxidized and decomposed to produce particles and glue Is more serious is the system pipeline in the formal operation before the rinse without a lot of impurities.
