  If the hydraulic wrench is not well maintained, it is also easy to be polluted. There are three main sources of it. Let's take a look at it together.

  Contamination from hydraulic wrench systems

  Particles generated by the wear of components during the operation of the system, sand particles falling off castings, metal particles falling off from pumps, valves and joints, particles and glue generated by the oxidation and differentiation of rust in the pipeline and its oil. It is more serious that there are many impurities in the system pipeline that have not been flushed before it is officially put into work.

  Internal pollutants

  The contaminants remaining in the hydraulic wrench components during processing, installation, debugging, packaging, storage, transportation and installation. Of course, these processes cannot be prevented, but they can be minimized. Some special components need to be installed and debugged. in a clean room or clean bench environment.

  Externally intruded contaminants

  External intrusion pollutants are mainly grit or dust in the atmosphere, generally through the hydraulic wrench oil tank air hole, the sealing shaft of the oil cylinder, the pump and the motor and other shafts to invade the system. Mainly the use of environmental impact.
