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. 4, centrifugal health self priming pump is fixed with supporting leg under electric machine assembly 15, electric machine assembly 15 is defeated Outlet is connected with centrifugal pump 14.Centrifugal pump 14 includes pump case, has pump chamber, the built-in impeller of pump chamber in pump case；It is pumped in centrifugal pump 14 The water inlet pipe and outlet pipe being connected to pump chamber are installed, water outlet tube end is equipped with titting water outlet 13 on shell；Centrifugal pump 14 is logical Electric machine assembly 15 is crossed to provide power, with trandfer fluid.This part is the prior art, does not do tired state.

Water inlet pipe includes the water inlet pipe straight pipe 4 connecting with centrifugal pump 14,4 outer end of water inlet pipe straight pipe be connected with vertically to Elbow 3 under the water inlet pipe of upper 90-degree bent, again to horizontal direction 90-degree bent after 3 upper end of elbow is connected with vertically upward under water inlet pipe Water inlet pipe on elbow 2, elbow 2 connects horizontal water inlet pipe connector 1 on water inlet pipe.Water inlet pipe connector 1 is higher than water inlet pipe straight tube Section 4.On water inlet pipe under elbow 2, water inlet pipe the center line of 4 three parts of elbow 3 and water inlet pipe straight pipe and centrifugal pump 14 rotation Turn center line on the same perpendicular, makes 14 pump chamber of centrifugal pump, circulating reflux pipeline, cavity composed by water inlet pipe in this way Have the function of storing liquid, after ensure that liquid is added for the first time in centrifugal pump 14, water inlet pipe, pump chamber and circulation when next time uses Remain to save the circulating liquid of sufficient amount in return line, to complete self-suction function.

A circulating reflux pipeline is connected between 14 pump chamber bottom of 4 bottom of water inlet pipe straight pipe and centrifugal pump, is recycled back to Flow tube road is specifically:

14 pump chamber bottommost of centrifugal pump connects return pipe lower contact 12, bores under 12 lower end of return pipe lower contact connection return pipe Pipe 11, fast assembling-disassembling hoop component 10 under 11 lower end of Taper Pipe connection return pipe under return pipe, fast assembling-disassembling clip group under return pipe 10 lower end of part connects trap 8, and (water polo 9 is closed in the interior placement) upper end of trap 8 connects fast assembling-disassembling clip group on return pipe Part 7,7 upper end of fast assembling-disassembling hoop component connects return pipe epicone pipe 6 on return pipe, and 6 upper end of Taper Pipe connects return water on return pipe Pipe top connection 5,5 upper end of return pipe top connection connect water inlet pipe straight pipe 4.The center line and water inlet pipe of entire circulating reflux pipeline Center line and 14 rotation centerline of centrifugal pump on the same perpendicular.And trap is located at extreme lower position, it can be effective Liquid is saved, the air duct of inlet tube and 14 pump chamber of centrifugal pump is cut off, water seal effect is effectively played, centrifugal pump is made to realize self-priming Function.

It closes water polo 9 and uses sanitation-grade ball, diameter is less than Taper Pipe under Taper Pipe 6 on trap 8, return pipe and return pipe The internal diameter of 11 big ends, greater than the internal diameter of 11 small end of Taper Pipe under Taper Pipe 6 on return pipe and return pipe.Make to close water polo under self-priming operating condition Since gravity is located at the lowest part of trap, and circulating reflux pipeline is opened, it is smooth in the case where being centrifuged pump condition to be moved to Taper Pipe 6 on return water are closed water return pipeline.

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 Effectively opened and closed under the action of water polo, on return pipe under Taper Pipe and return pipe Taper Pipe in pairs using also ensuring that closing water polo will not move To except trap, keep safety higher, line loss can also be effectively reduced using Taper Pipe, increases the uniform of fluid flowing Property, slough is avoided the occurrence of, corner or spot as yet untouched by a clean-up campaign is eliminated, guarantees sanitation performance.

Circulating reflux pipeline uses on return pipe fast assembling-disassembling hoop component under fast assembling-disassembling hoop component and return pipe, Dismantle circulating reflux pipeline quickly, convenient for checking reflux and the sanitary condition in circulating reflux pipeline.Meanwhile passing through Fast assembling-disassembling hoop component is dismantled very easily to be vented the liquid in centrifugal pump pump chamber, it in winter can be with effective protection pump case. 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 falls to the extreme lower position of trap, circulating reflux pipeline is beaten It opens, but since 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. Gas and liquid under the turning effort of centrifugal pump pump chamber inner impeller in water inlet pipe are pumped to promoting the circulation of qi liquid of going forward side by side in impeller and are mixed It closes, gas and liquid mixture by force feed to pump case runner, separate and pass through in pump case by the portion gas in gas and liquid mixture The vertical outlet pipe of centrifugal pump is discharged, and the mixed liquor in remaining pump case runner passes through trap since gravity declines Into water inlet pipe straight pipe, liquid is constantly recycled between circulating reflux pipeline and pump chamber like this, constantly water inlet pipe Interior gas discharge completes the self-priming operating condition of centrifugal pump until the gas on water inlet pipe road is fully drained.When gas is arranged completely After out, impeller enhances liquid pumpage, and pressure increases rapidly in pump case runner, and return pipe liquid is due to pressure and gravity Collective effect flow velocity increases, and promotion, which is closed on water polo, moves to Taper Pipe closing water return pipeline on return pipe, and pump enters centrifugation pump condition.Such as The liquid itself that fruit is pumped is high gassiness quantity of fluid, and such as CIP liquid, then pump can pump liquid under high air content, in self-priming work It works under condition.

The utility model structure is more compact simple, and circulating reflux pipeline is shorter, and hydraulic loss is smaller, and sanitation performance is more It 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, examine Repair, observe it is very convenient.In addition its superior sanitation performance, high efficiency, low noise, height can performance, have high practical valence Value, is worthy to be popularized.

The novel sanitation self priming pump not only maintains the sanitation performance requirement of sanitary centrifugal pump, but also common health Type centrifugal pump has been transformed into the centrifugal hygienic self priming pump with self-suction function, is well positioned to meet current food, dairy products, drink Material, beer, pharmaceutical industry CIP cleaning system needs.It is but also widely used for conveying gas-liquid mixed liquid and under self-priming operating condition Pump sanitation-grade liquid.
