Description
[technical field] the present invention relates to a kind of suction centrifugal pump, and this pump can have been realized centrifugal pump exhaust diversion, pump the liquid full process automatization.
Need pour water earlier with bottom valve before [background technique] general centrifugal pump proper functioning, when suction sleeve and the pump housing all are full of water, when the air emptying was reached vacuum, pump could start pumped liquid, has increased suction resistance during work.In order to solve the problems referred to above that the centrifugal pump start-up course exists, centrifugal pump self can have self-priming apparatus, as the patent No. is the self-priming centrifugal pump of the disclosed novel band air extracting wheel of 97217078.2 patent of invention, and this pump is established an air extracting wheel on the axle between bonnet and the self-priming volute; Have intakeport with the corresponding bonnet of air extracting wheel; Be provided with a ring-shaped air chamber with the end face of the corresponding self-priming volute of air extracting wheel, ring-shaped air chamber is provided with a relief opening.The patent No. is the disclosed self-priming centrifugal pump of 97225806.x patent of invention for another example, on the main shaft of this pump driving wheel is housed, and driving wheel drives piston cylinder work by follower, eccentric shaft and connecting rod thereof.Above-mentioned self-priming centrifugal pump all has moisture trap and plunger self-priming apparatus, can reach the self-priming purpose of bleeding, but limit by its structural design, still has shortcoming such as must pour water in moisture trap before the startup, pumping efficiency is low, the time is long, the pump housing is excessive.
[summary of the invention] the object of the present invention is to provide a kind of self-priming centrifugal pump, and this pump can have been realized centrifugal pump exhaust diversion, pump the liquid full process automatization.
The objective of the invention is to realize by following technological means.
A kind of self-priming centrifugal pump, wherein centrifugal pump partly comprises centrifugal pump body and is installed in centrifugal pump impeller on the pump shaft, the pump housing is provided with liquid inlet and outlet, it is characterized in that being equipped with on the same pump shaft in said centrifugal pump body rear portion the water ring vaccum pump that water ring vacuum room cover, water ring vacuum impeller and water ring vaccum pump body are formed, vacuum pump body is provided with the water filling outlet valve, be connected with air-breathing aqueduct between vacuum pump body and the centrifugal pump body, the centrifugal pump body outlet end is equipped with the pump discharge valve.Above-mentioned water ring vacuum room cover and water ring vaccum pump body fit on the pump shaft by the axle encapsulation; The water ring vacuum impeller rotates together in company with pump shaft.On the above-mentioned pump shaft bearing support is housed, the anterior cavity near the water ring vacuum room cover of bearing support is the water ring chamber, forms the water ring vaccum pump active chamber with the cavity of water ring vaccum pump body.The water ring chamber of bearing support is provided with the water filling outlet valve, is connected with air-breathing aqueduct between the water ring chamber and the pump housing, and water filling outlet valve and air-breathing aqueduct are connected respectively with water ring chamber on the bearing support.
When power engine starts, the water ring vacuum impeller is just devoted oneself to work immediately, by air-breathing aqueduct with the air in suction line and the centrifugal pump body, the active chamber of continuous low interest such as vacuum pump, under the effect of water ring vacuum impeller, air is discharged by the water filling outlet valve, vacuumize to reach, and water is attracted into purpose in the centrifugal pump body thereupon, finish the air-breathing diversion of water pump, pump the liquid overall process.
Self-priming centrifugal pump provided by the present invention thoroughly solves the drawback that Ordinary Centrifugal Pumps can not self-priming.During this pump work, without bottom valve, without hand pump, without vacuum pump, without water diversion apparatuss such as pressurized tanks, need not pour water, as long as to the indoor injection 3Kg of water ring water, just can directly start shooting during first start, start in back two minutes, centrifugal pump will suct water automatically, and pump just changes over to automatically and normally pumps liquid working.Later each startup need not be to the indoor water that adds of water ring, and directly the just automatic proper functioning of starting up can realize that the exhaust of centrifugal pump absorbs water, pump the liquid full process automatization.Centrifugal pump and water ring vaccum pump are the water ring vacuum self-priming centrifugal pump of integral type, realized that self-priming changes proper functioning then automatically over to, the labor intensity when not only alleviating the pump start greatly, and have simple in structure, practical, convenient operating maintenance, advantage such as price is low.
This pump can replenish from the water tank of trend power engine (diesel engine) by the water filling drain tap and add water, alleviates water pump operator's labor intensity, and this also is that Ordinary Centrifugal Pumps is difficult to accomplish.
[description of drawings] Fig. 1 is an embodiment of the invention structural representation.
Introduce the embodiment of the invention in detail below in conjunction with accompanying drawing.
[embodiment] as shown in Figure 1, the water ring vacuum self-priming centrifugal pump that present embodiment provided, pump self is made up of water ring vaccum pump and centrifugal pump two-part, wherein centrifugal pump partly comprises centrifugal pump body 12 and is installed in centrifugal pump impeller 13 on the pump shaft 4, the pump housing 12 is provided with liquid inlet 16 suction bend pipes and joint 17 and outlet 15 valve bodies, and outlet 15 1 ends of the pump housing 12 are equipped with pump discharge valve 14.Be equipped with bearing support 3, water ring vacuum room cover 8, water ring vacuum impeller 9 and the water ring vaccum pump body 11 that has the water ring chamber on the same pump shaft 4 in the pump housing 12 rear portions, form water ring vaccum pump.Water ring vacuum room cover 8 and water ring vaccum pump body 11 are assemblied on the pump shaft 4 by outside framework oil seal 7 and mechanical seal 10 respectively.Water ring vacuum impeller 9 rotates together in company with pump shaft 4, by bearing 2 bearing support 3 is housed on the pump shaft 4.Bearing support 3 anterior cavitys near water ring vacuum room cover 8 are the water ring chamber, form the water ring vaccum pump active chamber with the cavity of water ring vaccum pump body 11.The water ring chamber 19 of bearing support 3 is provided with water filling outlet valve 5, is connected with air-breathing aqueduct 6 between the water ring chamber 19 and the pump housing 12, and water filling outlet valve 5 and air-breathing aqueduct 6 are connected respectively with water ring chamber 19 on the bearing support 3.The bottom of above-mentioned centrifugal pump body 12 and vacuum pump body 11 is respectively equipped with drain screw 18.One end of pump shaft 4 is equipped with belt pulley 1.
Because water ring vacuum impeller 6 and centrifugal pump impeller 13 are contained on the same pump shaft 4, as long as when power engine starts, two impellers are high speed rotating simultaneously thereupon also.The water ring vacuum impeller 6 of high speed rotating has just been finished air-breathing, exhaust, has been vacuumized diversion work in the water ring vacuum work chamber, and water has been full of the pump housing 12 of centrifugal pump thereupon.And the centrifugal pump impeller 13 of high speed rotating just produces pressure in the centrifugal pump body 12, the outlet valve 14 of the pump housing 12 is opened automatically, thereby made centrifugal pump change proper functioning over to.Therefore, realized exactly the water ring vacuum self-priming centrifugal pump of water ring vaccum pump and centrifugal pump integral type the exhaust diversion, pump the liquid full process automatization.
