Specific implementation mode
Below in conjunction with Figure of description, the utility model is described in further details, and provides specific implementation mode.
The utility model central air-conditioning recirculated cooling water backwashing system, its purpose is to prevent cycle impurities in water stifled
Plug causes air-conditioner set heat exchange efficiency to decline, and needs the filter on every unit water inlet pipe of frequent clean, needs largely to sell
Manpower and materials afterwards solve difficult point after sale, and cycle impurities in water is allowed to be maintained at a low range by the way that backwashing system is arranged
It is interior, keep air-conditioning system more stable and energy saving.
Its structure specifically includes vibration means for main pipe for supplying water 2 and the return water supervisor 3 of connection cooling tower 1 and air-conditioner set, 2 He of vibration means for main pipe for supplying water
It is both provided with pressure gauge 12 and thermometer 13 on return water supervisor 3, cooling water pump 4 and main filter are additionally provided on vibration means for main pipe for supplying water 2,
Be provided with the first valve 5 on return water supervisor 3, be provided with the second valve 6 on vibration means for main pipe for supplying water 2, vibration means for main pipe for supplying water 2 and return water supervisor 3 it
Between 7 and second connecting branch 8 of the first connecting branch arranged in a crossed manner, third valve 9 is provided on the first connecting branch 7, second connects
It connects and is provided with the 4th valve 10 and filter 11 on branch pipe 8, wherein the first valve 5, the second valve 6, third valve 9 and the 4th
