Abstract
The utility model relates to pumps, in particular to a strong air exhausting device for a self-priming pump. The strong air exhausting device comprises a throat part, a strong air exhausting device and a water inlet pipe. The strong air exhausting device is arranged on the lower portion in an inner cavity of a water diversion tank, an air suction pipe is arranged above the throat part in the strong air exhausting device, and the other end of the strong air exhausting device is connected with the inlet end of the water pump. According to the strong air exhausting device for the self-priming pump, the Venturi effect is adopted, and a Venturi pipe is manufactured; when liquid enters the throat part in the strong air exhausting device, the throat part will produce low pressure, air or liquid on the upstream of the air suction pipe is directly sucked and mixed with liquid in the throat part of the strong air exhausting device, the liquid is pumped out after being pressurized by the water pump, and the water pump still has the good air exhausting function under the ultra-low load. According to the strong air exhausting device for the self-priming pump, the problem that air exists in a water diversion tank in the prior art is solved, normal operation of the pump is ensured, the production efficiency of the pump is improved, and the service life of the pump is prolonged.
Description
Technical field
The utility model relates to pump, particularly relates to the forced exhaust device that a kind of self-priming pump is used.
Background technique
As shown in Figure 1, be traditional self-priming pump and the structural representation of water diversion tank, its working principle: be first water diversion tank and pump case all to be filled with to water before pump, after starting of pump station, the water sucking in water diversion tank is transported to outlet, liquid level in water diversion tank is declined, and form certain vacuum; Water in pond falls pipe waterfall by intake pipe, waterfall and is down to water diversion tank under atmospheric pressure effect, with in original inlet pipeline and the air of tank top form gas-liquid mixed, after then being pressurizeed by water pump, send.Air in water diversion tank is pulled away continuously, makes the water level in water diversion tank constantly increase, until water diversion tank is all full of water.Its deficiency has two aspects: 1, when water pump carrying capacity significantly declines, waterfall amount of precipitation lowers greatly, will be unfavorable for that in water diversion tank, air is taken out of; 2, after each termination of pumping, in intake pipe and water diversion tank top has been full of again air, and liquid level can decline gradually in water diversion tank, in water diversion tank, air increases gradually, after certain hour, even if water pump carrying capacity is normal, waterfall precipitation stream also cannot all be taken away the air in water diversion tank.Air band in water diversion tank is not walked, and causes vacuum breaking, water pump idle running phenomenon in the time of can causing water body flow, affects pump and runs well.
Summary of the invention: the purpose of this utility model is exactly the forced exhaust device that will provide a kind of self-priming pump to use, it can overcome the above problem that prior art exists.The purpose of this utility model is to realize like this, the forced exhaust device that a kind of self-priming pump is used, comprise throat, forced exhaust device, intake pipe, it is characterized in that: the bottom in water diversion tank inner chamber is provided with a forced exhaust device, the throat top in forced exhaust device is provided with sucking pipe, and the other end of forced exhaust device is connected with the entrance point of water pump.
Described forced exhaust device, employing be Venturi effect, be made into Venturi tube;
Described forced exhaust device can be arranged on import or the water delivery side of pump of water pump.
The utility model adopts Venturi effect, be made into Venturi tube, liquid enters after the throat in forced exhaust device, throat place can produce low pressure, air or the liquid of direct inhale pipe upstream, mix with the liquid in forced exhaust device throat, after being pressurizeed, send by water pump, water pump still has good degassing function under utmost point low-load.Solve the problem that has air in prior art water diversion tank, guaranteed the normal operation of pump, improved the manufacturing efficiency of pump, extended the working life of pump.
Accompanying drawing explanation:
Fig. 1 is traditional self-priming pump and the structural representation of water diversion tank;
Fig. 2 is the utility model structural representation;
1. throat, 2. forced exhaust device, 3. intake pipe, 4. water diversion tank, 5. pipe falls in waterfall, 6. sucking pipe, 7. water pump.
Embodiment
below in conjunction with accompanying drawing, the utility model is described in further detail;
The forced exhaust device that a kind of self-priming pump is used, comprise water diversion tank 4, pipe 5 falls in waterfall, sucking pipe 6, it is characterized in that: the bottom in water diversion tank 4 inner chambers is provided with a forced exhaust device 2, throat 1 top in forced exhaust device 2 is provided with sucking pipe 6, and the other end of forced exhaust device 2 is connected with the entrance point of water pump 7.
Described forced exhaust device 2, employing be Venturi effect, be made into Venturi tube;
Described forced exhaust device 2 can be arranged on the import of water pump 7 or the outlet of water pump 7.
During concrete enforcement, forced exhaust device has been installed in water diversion tank, can have been solved the deficiency that prior art exists.What forced exhaust device adopted is Venturi effect, liquid enters after throat, throat place can produce low pressure, air or the liquid of direct inhale pipe upstream, mix with the liquid in forced exhaust device throat, after being pressurizeed by water pump, send, can guarantee that like this water pump still has good degassing function under utmost point low-load.
