The utility model is set to further: the side on described fixed base is provided with through hole, and through hole internal fixtion is provided with pressure transducer.
The utility model is set to further: the opposite side on described fixed base is provided with the mounting hole that position and turbine match, and is provided with Hall transducer in mounting hole.
The utility model is set to further: the downside on the madial wall of described fixed base is uniformly distributed with several struts along the circumference, the end winding support of strut is connected with turbine axle sleeve, turbine shaft puts fixed cover and is provided with the turbine shaft protruded upward, and the upper end of turbine shaft is arranged with in trumpet-shaped retainer ring.
The utility model is set to further: the opening that the downside of described pump head is arranged is sealed by blanking cover.
The utility model is set to further: described gas tank cover internal fixtion is provided with pressure controller.
By adopting technique scheme, the technique effect that the utility model reaches is:
1, the auxiliary of gas tank is set up in employing, strengthen the pressure in inner chamber body, and then enhancing hydraulic pressure, water-outlet quantity is increased, and water outlet adopt turbotype structure, make structural sensitivity high, cost is low, and radial rotary induction sensitivity is also high, and working efficiency is high, quality assurance is high, uses middle Safety performance also high;
2, when water pump is cut off the water supply suddenly when normally using or pond Li Shui drains, inductor passes to controller signals, and whether controller control pump enters dry operating condition, if dry running, then pump automatic cut-off power, out of service, the function of teaching display stand protection, uses middle Safety performance also high;
3, when pump discharge valve closing, this Time Controller senses pressure by pressure transducer, and by the size of flow or with or without, now pump enters Self-Test Diagnostics according to controller, maintain pressure if continue and cut off motor power voluntarily without pump after flow number second and enter holding state, when pump discharge valve open, pressure in pump chamber is down to the breakout pressure point of pressure transducer rapidly, now pump brings into operation, realize automatic start-stop function, working efficiency is high, and quality assurance is high, uses middle Safety performance also high;
4, there is good small flow monitoring function, pressure when the pipeline that pump connects micro-leakage in pump chamber is also by the pressure-activated point being reduced to pressure sensor device slowly, now pump starts to enter abnormal operational conditions, and user also not easily finds this kind of situation, by the flow in pump and pressure, this Time Controller can judge that pump enters abnormal operational conditions, and pump chamber internal pressure is high, flow without or hour, pump will cut off the electricity supply voluntarily enter permanent shut down condition until user again plug-in just can use.
