Outdoor anti-explosion shielding type high-temperature high-suction-stroke pump

The invention provides an outdoor anti-explosion shielding type high-temperature high-suction-stroke pump. The outdoor anti-explosion shielding type high-temperature high-suction-stroke pump comprises an outer sleeve, a conveying pump, a driving motor, an inner sleeve and an air delivery device. The conveying pump is fixedly connected to the lower end of the outer sleeve. The driving motor is in driving connection with the conveying pump and is fixedly arranged in the outer sleeve. The inner sleeve is fixed in the outer sleeve, an annular space is formed between the inner sleeve and the outer sleeve, the annular space is communicated with a central through hole of the inner sleeve, and the top end of the central through hole and the top end of the annular space are communicated with the atmosphere. The air delivery device is used for delivering air form the top end of the central through hole into the central through hole and delivering the air out from the top end of the annular space after the air flows through the driving motor and the annular space. The outdoor anti-explosion shielding type high-temperature high-suction-stroke pump is good in cooling effect, and the heat dissipating effect of the driving motor is improved.
