Working Principle
When the equipment is put into movement, the water from the tap-water pipe-net flows into the flow stabilizing can. When the water supply capacity of the pipe-net can meet with the demand of use, the pressure of it is kept with the normal water supply range, the negative-pressure preventing module controlled electric valve is opened and the pump moves to carry out the pressure-overlapped water supply; While the said capacity can not meet with the demand, the pipe-net pressure is lower than that for normal water supply, the said module automatically adjusts the opening of the electric valve till its being closed, at this time water supply by the flow stabilizing can is automatically switched in. The vacuum eliminator on the said can is opened therewith, preventing a negative pressure from being produced inside of the can.
| Varieties of water supply equipment | Allocation characteristics | Features of water supply | Conclusion |
| Model WFY cannery type pipe-net pressure-overlapped(non-negative-pressure) Water supply equipment | Flow stabilizing can,pump unit,pipeline valve,control meter,monitor module,pressure stabilizing can(selected by clients)etc. | Pipe-net pressure-overlapped water supply,effectively Utilize the municipal works pipe-net’s pressure,compensate as much as the balance. | Energy-saving,more than that of other water supply equipments by20~40% |
| Compact structure,no need to build up a water pool and a large water tank | Saving the investment,small land area.Compared with the traditional water supply,save the construction cost by over50% | ||
| The water source directly comes from the municipal works pipe-net and always in the cycled state,without held-up and causing the water quality to be polluted. | Clean and environmental protection water source | ||
| The control system uses an advanced inverter control know-how and can do remote monitor and man-machine interface operation,of overload,short-circuit,over-voltage, under-voltage,lack-of-phase etc.protections | Full functions,high degree of intelligence | ||
| All the allocations are of the domestic and foreign famous brands. | Advanced product,reliable quality | ||
| Traditional water supply equipment | Water pool or water tank,pump unit,pipeline valve, control meter etc | Supply water by way of trans-pressuring in the water tank or pool,the water therein is easy to be polluted and difficult to be cleaned,need a large land area. | No way to utilize the municipal works pipe-net’s pressure,high cost at cleaning and maintenance |
