To in 10 years, country will increase input of the public finance to water conservancy, go in a big way construction of water conservancy works.In recent years, various regions irrigation and water conservancy
Input significantly reinforce, farmland water conservancy works are large in number and widely distributed, irrigate, wherein horizontal small centrifugal pump large number of with drainage pumping stations
With mixed-flow pump using more, but this pump-type needs artificial recharge that could start before starting in the past, time-consuming and laborious；Using vacuumizing
The method of pump starts, and is often difficult to realize and automatically controls, if to automatically control, it is necessary to increase by two solenoid valves, increase whole
The cost of a pump installation.
Utility model content
The utility model needs artificial recharge that could start before activation for existing centrifugal pump and mixed-flow pump, time-consuming to take
Power；Started using the method for vacuum pumping pump, can only be manually operated, it is difficult to realize to automatically control, and realize automatic startup, then it is necessary
The deficiencies of two solenoid valves of increase at vacuum pump and mixed-flow pump, centrifugal pump water outlet, this undoubtedly increases the cost of entire pumping plant,
It proposes that a kind of mixed-flow pump exempts to vacuumize automatic starting device, using single-phase spiral vortex self-suction pump to mixed-flow pump, centrifugation pump priming, works as note
When water depth can flood mixed-flow pump, centrifugal pump impeller, sensed using the level sensing in mixed-flow pump, the installation of centrifugal pump corresponding position
Device will detect signal transmission and start mixed-flow pump, the main startup of centrifugal pump to automatic transfer switch to stop single-phase spiral vortex self-suction pump
Switch reaches and installs simple, automatic start-stop, low-cost purpose.
The technical solution of the utility model is：A kind of mixed-flow pump exempts to vacuumize automatic starting device, including rack, and setting exists

Control device and switching equipped with interconnection switch, and the level detection sensor, pressure sensor are respectively connected to control
On device, the switching switch forms break-make with motor and connect.
The water injecting pump is single-phase spiral vortex self-suction pump.
The level detection sensor is arranged at the original annotation water hole of mixed-flow pump or vacuumizes at hole.
The control device is connected and composed by digit chip and microcontroller.
Described filling pipe one end stretches in intake pool, and the other end is tightly connected with outlet pipe, the close water outlet of check-valves
Pipe is arranged, and water injecting pump is arranged far from outlet pipe.
The beneficial effects of the utility model are：The utility model proposes a kind of mixed-flow pump exempt to vacuumize and automatic start dress
It sets, structure novel, operation principle is clear, by using single-phase spiral vortex self-suction pump to mixed flow pump priming, when water filling depth can flood
When mixed-flow pump impeller, signal is detected using the liquid level detecting sensor installed in mixed-flow pump corresponding position, to stop single-phase rotation
Whirlpool self priming pump, the starting switch of mixed-flow pump reach and install simple, automatic start-stop, low-cost purpose, with traditional mixed-flow pump
Starter is compared, and the present invention is at low cost, effect is good, can be widely applied to the irrigation pumping station of irrigation and water conservancy mixed-flow pump, centrifugal pump
On, especially on integral intelligent pumping plant.
