Specific embodiment

It is a specific embodiment of the utility model below, the utility model is described further now in conjunction with attached drawing.

In conjunction with shown in Fig. 1 to Fig. 5, a kind of centrifugal sanitary self-sucking pump is fixed with supporting leg, motor group under electric machine assembly 15 15 output end of part is connected with centrifugal pump 10.Centrifugal pump 10 includes pump case, has pump chamber, the built-in impeller of pump chamber in pump case；It is being centrifuged The water inlet pipe and outlet pipe for being equipped on 10 pump cases and being connected to pump chamber are pumped, water outlet tube end is equipped with titting water outlet 14；Centrifugation Pump 10 provides power by electric machine assembly 15, with trandfer fluid.This part is the prior art, does not do tired state.

Water inlet pipe includes the water inlet pipe straight pipe 3 connecting with centrifugal pump 10, and water inlet pipe straight pipe 3 connects check valve 2, unidirectionally The axis of valve 2 and centrifugal pump 10 is on the center line of same level；2 outer end of check valve is connected with water inlet pipe connector 1；Check valve 2 With unidirectional cutoff function, it ensure that 10 pump chamber of centrifugal pump, circulating reflux pipeline, cavity has storing liquid composed by water inlet pipe The function of body, after ensure that liquid is added for the first time in centrifugal pump 10, when next time uses in water inlet pipe, pump chamber and circulating reflux pipeline Remain to save the circulating liquid of sufficient amount, to complete self-suction function.

A circulating reflux pipeline is connected between 10 pump chamber bottom of 3 bottom of water inlet pipe straight pipe and centrifugal pump, is recycled back to Flow tube road is specifically:

Return pipe lower contact 9 is connected in 10 pump chamber bottom of centrifugal pump, 9 lower end of return pipe lower contact connects under return pipe quickly Hoop component 8 is dismounted, 8 lower end of fast assembling-disassembling hoop component connects trap 7 under return pipe, and 7 upper end of trap connects back to Taper Pipe 6 under water pipe, fast assembling-disassembling hoop component 4 on 6 upper end of Taper Pipe connection return pipe under return pipe, fast assembling-disassembling card on return pipe It binds round 4 upper end of component and connects return pipe epicone pipe 11,11 upper end of Taper Pipe connects return pipe top connection 13 on return pipe, connects on return pipe First 13 upper end connects water inlet pipe straight pipe 3.The center line of entire circulating reflux pipeline and the center line and centrifugal pump 10 of water inlet pipe Rotation centerline is on the same perpendicular.And trap is located at extreme lower position, can effectively save liquid, cuts off inlet tube With the air duct of pump case, water seal effect is effectively played, centrifugal pump is made to realize self-suction function.

It closes water polo 12 and uses sanitation-grade ball, diameter is less than 4 internal diameter of fast assembling-disassembling hoop component, return pipe on return pipe The internal diameter of 6 big end of Taper Pipe under upper Taper Pipe 11 and return pipe, greater than in 6 small end of Taper Pipe under Taper Pipe 11 on return pipe and return pipe Diameter.Volute spring 5, which is located at, closes 12 lower part of water polo, and volute spring big end outer diameter is greater than the small end inner diameter of Taper Pipe 6 under return pipe, taper Spring small end inner diameter is less than the diameter for closing water polo.The effect of volute spring is that water polo is closed in support, avoids closing water polo whereabouts, thus not Conducive to liquid reflux under self-priming state.The top that water polo falls in volute spring in self-priming operating condition at present is closed, is recycled back to flow tube at this time Road is opened, and normal reflow is kept, and is entered centrifugal pump operating condition after completing self-priming, is then closed that water polo is smooth to be moved to Taper Pipe 11 on return water, It is closed water return pipeline, so that centrifugal sanitary self-sucking pump is worked under pure centrifugation pump condition, prevents backflow leakage, improve efficiency.

Using Taper Pipe under Taper Pipe on return pipe and return pipe in circulating reflux pipeline, it can guarantee that circulating reflux pipeline is closing It is effectively opened and closed under the action of water polo, keeps safety higher, line loss can also be effectively reduced using Taper Pipe, increase fluid flowing Uniformity, avoid the occurrence of slough, eliminate corner or spot as yet untouched by a clean-up campaign, guarantee sanitation performance.

Plane composed by plane composed by circulating backwater pipeline axial line and water inlet pipe road is also common perpendicular at one In straight plane.Circulating reflux pipeline is using fast assembling-disassembling clip group under fast assembling-disassembling hoop component on return pipe and return pipe Part dismantles circulating reflux pipeline quickly, convenient for checking reflux and the sanitary condition in circulating reflux pipeline.Meanwhile Very easily the liquid in centrifugal pump pump chamber is vented by disassembly fast assembling-disassembling hoop component, can be pumped in winter with effective protection Shell.The industry of hygienic requirements high for pharmacy etc. can make pump case that need not individually install lower leakage fluid dram again.

Working principle:

In self-priming operating condition, water polo is closed since gravity is fallen on volute spring, circulating reflux pipeline is opened, but due to Trap is located at extreme lower position, still plays the role of water seal for the gas in water inlet pipe and pump chamber, outlet pipe.It is pumped in centrifugal pump Gas and liquid under the turning effort of intracavitary impeller in water inlet pipe are pumped in impeller and carrying out gas-liquid mixed, gas-liquid mixed Liquid by force feed to pump case runner, separate in pump case and by the vertical water outlet of pump by the portion gas in gas and liquid mixture Pipe is discharged, and the mixed liquor in remaining pump case runner enters water inlet pipe straight pipe by trap since gravity declines, Liquid is constantly recycled between circulating reflux pipeline and pump case like this, and constantly the gas in water inlet pipe is discharged, until The gas on water inlet pipe road is fully drained, and completes the self-priming operating condition of pump.After gas is fully drained, impeller pumps energy to liquid Power enhances, and pressure increases rapidly in pump case runner, and return pipe liquid is pushed since the collective effect flow velocity of pressure and gravity increases It closes on water polo and moves to Taper Pipe closing water return pipeline on return pipe, pump enters centrifugation pump condition.If liquid pumped itself is high Gassiness quantity of fluid, such as CIP liquid, then pump can pump liquid under high air content, work under self-priming operating condition.

The utility model water inlet pipe structure is simple, convenient for production, installation；Circulating reflux pipeline is short, close the movement of water polo away from From short, close and open that water return pipeline is more rapidly and sensitive, and high-efficient, hydraulic loss is small, and sanitation performance is good.The utility model Clever structure is easy to production, installation and removal, and fast quick-detach, installation especially may be implemented in maintenance, and maintenance, observation are very square Just.In addition its superior sanitation performance, high efficiency, low noise, height can performance, have high practical value, be worthy to be popularized.

The centrifugal sanitary self-sucking pump not only maintains the sanitation performance requirement of sanitary centrifugal pump, but also common Hygiene-type centrifugal pump has been transformed into the centrifugal sanitary self-sucking pump with self-suction function, is well positioned to meet current food, cream Product, beverage, beer, pharmaceutical industry CIP cleaning system needs.It is but also widely used for conveying gas-liquid mixed liquid and in self-priming work Sanitation-grade liquid is pumped under condition.
