Types Of Self-priming Pumps

Self-priming pumps are divided into the following categories according to their working principles: 1. Gas-liquid mixed type (including internal mixed type and external mixed type); 2. Water ring wheel type; 3. Jet type (including liquid jet and gas jet). The working process of the gas-liquid hybrid self-priming pump: due to the special structure of the pump body of the self-priming pump, after the pump stops, there is a certain amount of water in the pump body. After the pump starts again, due to the rotation of the impeller, the air and water in the suction pipeline Fully mixed and discharged to the gas-water separation chamber, the gas in the upper part of the gas-water separation chamber overflows, the water in the lower part returns to the impeller, and re-mixes with the remaining air in the suction pipe until all the gas in the pump and suction pipe is discharged, and the self-flow is completed. Suction, and pump normally. The wheeled self-priming pump of water ring is that a water ring wheel and a water pump vane are combined in a housing, and the gas is discharged by means of the water ring wheel to realize self-priming. After the pump works properly, the passage of the water ring wheel and the water pump vane can be blocked by a valve, and the liquid in the water ring wheel can be bleed off. The jet-type self-priming pump is combined by centrifugal pump and Jet injector (or sparger), relies on injection apparatus, causes vacuum to realize suction at the nozzle place.

According to the type of supporting power machine of the pump, it is divided into self-priming pump matching with electric motor and self-priming pump matching with diesel engine.

According to the structure and working characteristics of self-priming function, it can be divided into inner sliding type, outer sliding type, water ring wheel type and other types. The transmission methods include direct drive (including inner shaft) and belt drive. The import diameter is 25-200mm.
