How Does the Surface Cleaning Unit Work?

SCU Surface Cleaning Unit utilizes carrier machine’s hydraulic system as power source. It produces high-pressure water for surface cleaning and powerful vacuum to suck the washing water.

  1. Hydraulic oil flow is led from the hydraulic system of the carrier machine into the HMV Hydraulic modular Valve System where it is led to the hydraulic equipment such as HPW Hydraulic High Pressure Water Pump and HCF Hydraulic Centrifugal Fan which are powered by hydraulics.
  2. HPW Hydraulic High Pressure Water Pump sucks water from a reservoir and pumps high-pressure water through rotating flat spray nozzles onto the washable surface.
  3. The SCU has a cover which prevents the water, dirt and rocks from spreading to the environment.
  4. HFC Hydraulic Centrifugal Fan vacuums the water and dirt from the surface into an integrated container for recycling.
  5. Optionally the high-pressure water can be led to a washing pipe for street washing or to the washing pistol for regular pressure washing.
  6. Different functions such as the suction, can be switched on and off depending on the intended use.
