Further being improved to of the utility model, said vacuum restraining device is near said water intake setting.
Further being improved to of the utility model, said no negative pressure energy-saving pump also is provided with control system, and said control system is connected in said sensor.
Further being improved to of the utility model offers sewage draining exit on the said pump case.
Compared to existing technology, the no negative pressure energy-saving pump of the utility model is provided with mechanical type vacuum restraining device and electric detection of negative pressure sensor double mechanism, improves the reliability of " no negative pressure " function greatly.Have the mechanical type vacuum suppresser,, also can guarantee can not produce negative pressure the upper level water supply network even when the electric signal of detection of negative pressure sensor breaks down.The electric part and the network of rivers isolate more completely, and the electrical safety coefficient improves greatly.The easy dismounting of equipment, maintenance, easy maintenance, fault more comes to light easily intuitively, and the versatility of aftermarket attachment improves, and has higher mechanical efficiency.The utility model belongs to the secondary pressurized equipment of water supply network, can make full use of the water pump that former water supply network has the saving power consumption of hydraulic pressure, realization secondary pressurizing system and can not produce negative pressure at feed-water end.Be applied to especially to live, the secondary pressurization between production water supply and municipal network water supply.
Description of drawings
Fig. 1 is that the utility model does not have negative pressure energy-saving pump front view.
Fig. 2 is that the utility model does not have negative pressure energy-saving pump partial sectional view.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is further specified.
See also Fig. 1 and Fig. 2, the utility model provides a kind of no negative pressure energy-saving pump 10, comprises that Power Component 11, water pump 13 and vacuum suppress assembly 15, and Power Component 11 is connected in water pump 13 and for water pump 13 power is provided, and water pump 13 is used to accomplish the pressurization of liquid.In the present embodiment, Power Component 11 is a motor, it is understandable that, Power Component 11 can be selected the motor of different size according to actual needs for use.
Water pump 13 is provided with the pump housing 131, pump case 133, pump shaft 135, impeller 137 and fluid director 139.The pump housing 131 is arranged among the pump case 133, and pump shaft 135, impeller 137 and fluid director 139 are arranged in the pump housing 131.Impeller 137 is sheathed on pump shaft 135 and rotates around pump shaft 135, and fluid director 139 is arranged at pump shaft 135 ends.Pump case 133 is provided with water intake 1331, water outlet 1333 and sewage draining exit 1335.The pump housing 131, pump shaft 135, impeller 137 and fluid director 139 are processed by stainless steel.It is understandable that the pump housing 131, pump case 133, water intake 1331 and water outlet 1333 can be selected different size according to actual needs for use, this specifications parameter is main relevant with the water supply capacity of water pump 13.
Vacuum suppresses assembly 15 and comprises vacuum restraining device 151 and sensor 153; Vacuum restraining device 151 is provided with air intake valve (figure does not show); Vacuum restraining device 151 is opened air intake valve when negative pressure appears in the water intake 1331 of pump case 133; The water intake 1331 that makes extraneous gas entering pump case 133 is with the pressure in the balance water intake 1331, and sensor 153 provides electric signal when in the pump case 133 trend that negative pressure occurs being arranged.Vacuum restraining device 151 is provided with near water intake 1331.No negative pressure energy-saving pump 10 also is provided with control system, and control system is connected in sensor 153.
