The invention relates to a novel turbo-type pneumatic
submersible pump with multiple nozzles, which comprises a pump body, a turbo casing, a turbo cover plate, a rotary shaft, a turbo, a supporting device, a sealing socket, a
water wheel, a pump cover and an anti-
fouling seat. A water outlet joint is arranged on the pump body, an annular air inlet
nozzle is fixedly connected to the lower end face of the turbo casing, an air inlet
pipe is fixedly connected to the circumference surface of the air inlet
nozzle, a main
airflow passage communicated with the air inlet
pipe inside the air inlet
nozzle circumferentially, N sub
airflow passages are uniformly distributed on the main
airflow passage in an upward extending manner, the N is the natural number larger than or equal to 2 and smaller than or equal to 6, and nozzles which are communicated with the sub airflow passages and disposed in vent holes on the turbo casing are arranged at the upper end of the air inlet nozzle. The novel turbo-type pneumatic
submersible pump with multiple nozzles is long in service life, simple in structure, low in cost and capable of realizing production in batch. Power of the pneumatic
submersible pump is increased by the common airflow passage and the multiple nozzles.
Noise is lowered by the aid of a silencer. Energy conversion rate is high due to the high-efficiency turbo which is cast precisely integrally. Due to a composite
impeller, the pneumatic submersible pump can be adaptable to
sewage containing large-particle impurities, and is high in flow and lift.
