A bottom valve is additionally arranged on an inlet pipeline, if the bottom valve is not tightly sealed, the pump cannot normally run when being started again, and the phenomenon of machine seal ablation is caused; the self-priming tank is additionally arranged at the inlet, the whole volume of the water pump is larger, and the capital construction cost is increased; the whole self-priming process can be completed only by adopting a vacuum pump auxiliary vacuumizing mode and ensuring that the check valve at the outlet of the water pump is in a completely sealed state.
2. The submersible pump works in a submerged side-out mode and comprises a submersible motor, a power cable, a signal protection cable, an oil chamber, a pump shell, an impeller, a mechanical seal and coupling device, a guide rod and the like, and the state protection is performed by self-protection through water leakage, electric leakage, overheating and overcurrent output signals in the operation process. The ground monitoring system can not display the state of the water pump in the submerged operation process, particularly invisible faults such as machine seal friction damage leakage, bearing temperature rise and the like. The shutdown frequency is high, emergency repair is not possible at all, only the whole pump set is lifted out of the water surface for maintenance, the maintenance cost is high, and the time is long.
3. The vertical long-axis mixed-flow pump and the vertical axial-flow pump are adopted, the pump is inserted into liquid for use, a plurality of easily damaged parts are provided, the lifting height is high, the flow passage part is immersed in the liquid, the installation and the maintenance are difficult, and the labor intensity and the maintenance cost of maintenance personnel are increased.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
In the figure: a water pump equipped with a fluidic device, comprising a pump body 1, characterized in that: the pump body 1 is provided with an exhaust port, the exhaust port is connected with a pipeline 2, the side surface of the pipeline 2 is sequentially connected with a filter 3, an electromagnetic valve 4 and a jet device 5 in a turbine device through pipelines, and the end part of the pipeline 2 is connected with a sensor 9; the turbine device is provided with a turbine booster fan 7 and a jet device 5; the sensor 9, the electromagnetic valve 4 and the turbine device are respectively connected with the control cabinet 8 through lines. The exhaust port connects the sensor 9, the electromagnetic valve 4, the filter 3, the jet device 5 and the turbine booster fan 7 in an airtight way through a connecting pipeline. The working principle is as follows: starting a control system, starting a turbo-charger fan, opening an electromagnetic valve, forming power airflow jet in a jet device by air pressure generated by the work of the turbo-charger fan to form vacuum, discharging air in a pump cavity and an inlet pipeline through a connecting pipe fitting, raising a conveyed medium under the action of atmospheric pressure until the whole pipeline and the pump cavity are full of the conveyed medium, sending a signal to a control box when a sensor is in contact with the medium, sending an instruction to the control box to start a water pump, normally operating the water pump, and simultaneously closing the electromagnetic valve.
The utility model has the advantages that:
1. under the suction working condition, a bottom valve is not required to be installed for drainage, water is not required to be manually injected into the pump or is not required to be introduced when the pump is used for the first time, and the medium can be discharged when the pump is started. Suitable for media that are remote from the water source or are not easily drained (reactive with water).
2. After the machine is stopped, no residual medium exists in the suction pipe and the pump cavity, and heat insulation measures are not needed to be taken for the pump and the suction pipe, so that the machine is completely suitable for being installed and used in winter, particularly in alpine regions under the condition of no heat insulation.
3. When the jet device is used for conveying sewage, muddy water and slurry, the power airflow formed inside the jet device is sprayed to form vacuum, and the turbo booster fan is not contacted with a medium, so that foreign matters entering the turbo booster fan can be effectively prevented, and the turbo booster fan is damaged. While the direct suction turbine structure cannot meet the requirement.
4. The foundation construction of a low-level pump room or a high-level water tank can be cancelled, the installation is carried out above the liquid level, the center of gravity is low, the size is small, the investment and the occupied area are saved, and the overhaul is convenient.
5. And a bottom valve is not needed, so that the suction loss is small and the efficiency is high.
6. The pump has the functions of starting at a high liquid level and stopping at a low liquid level, and also has an intelligent protection stopping device, so that the pump can automatically stop after a medium is emptied, can realize remote control, and saves electricity, manpower and material resources.
The above embodiments of the present invention are only examples for clearly illustrating the present invention, but not for limiting the scope of the present invention, and all equivalent technical solutions also belong to the scope of the present invention, and the scope of the present invention should be defined by the claims.
