Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is further described:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of self priming centrifugal pump, including centrifugal pump body 1, centrifugal pump body 1 is the Ordinary Centrifugal Pumps structure adopted, it is provided with blade wheel chamber 11, described blade wheel chamber 11 is provided with water inlet 12, and described water inlet 12 connects with water inlet pipe 3 and seals and be bolted, and described water inlet pipe 3 is provided with check valve 31.
Additionally, this utility model also has additional a gas-water separation bucket 2 on the basis of Ordinary Centrifugal Pumps, described gas-water separation bucket 2 is located at above centrifugal pump body 1, described blade wheel chamber 11 top is provided with on protruding upward one interface 13, described upper interface 13 connects with blade wheel chamber 11, and the bottom of described gas-water separation bucket 2 and upper interface are connected, and described gas-water separation bucket 2 connects a water return pipeline 4, described water return pipeline 4 connects with blade wheel chamber 11, and described water return pipeline 4 is provided with direct-operated regulator 41.
Described gas-water separation bucket includes staving 21, the diameter front segment pipe 22 less than staving diameter it is connected to bottom described staving, described front segment pipe 22 connects with upper interface 13 and seals and be bolted, described staving 21 be connected above the diameter rear segment pipe 23 less than staving diameter, described water return pipeline 4 is connected to the bottom of staving.Described upper interface 13 is in funnel-shaped structure.The described S-type structure of water inlet pipe 3, described check valve 31 is Wafer Check Valves.
nullBefore pump startup，In pump, first to pour into the liquid (cannot deposit higher than the liquid of Wafer Check Valves) to carry，Namely the top of gas-water separation bucket and water inlet pipe is entirely air，After centrifugal pump starts，Under the centrifugal action of impeller，Water in water inlet pipe is transported in gas-liquid separation bucket，Overflowed by the gas in the collision of liquid and inactive liquid and enter rear segment pipe，Form negative pressure in water inlet pipe simultaneously，On the one hand the air in whole water inlet pipe is entered in water inlet pipe by Wafer Check Valves，Liquid in gas-water separation bucket is emitted back towards the impeller place of Ordinary Centrifugal Pumps under suction function by water return pipeline high velocity spray on the other hand，In the process of injection, liquid sweeps along the gas in water inlet pipe，It is transported in gas-water separation bucket by centrifugal pump，Move in circles，Until the gas in whole water inlet pipe is all discharged in the rear segment pipe of gas-water separation bucket，Centrifugal pump normal operation，Along with the pressure in gas-water separation bucket raises，Direct-operated regulator in water return pipeline is closed under the effect of front and back pressure reduction，Centrifugal pump proceeds to normal operation，Removing when centrifugal pump starts in next time need not be again external to infusion liquid in pump，Repeat above step，Pump can normal operation.
