Abstract

The utility model discloses a spoon type liquid pump and consists of a pump sheel, an impeller, a pump axis, a liquid inlet and outlet. The utility model is characterized in that the pump shell is hollow and formed by the crossing of two circles; the liquid inlet hollow of the pump shell in the side with a liquid inlet pipe is provided with an impeller with spoon shaped blade and the other end of the pump shell is provided with a liquid hinder wheel with arched nicks. The liquid outlet pipe is positioned on the crossing part of the two circles and connects with each other in the tangent part. The impeller turn in the opposite direction with the liquid hinder wheel and the spoon shaped blade is matched with the arched nick. When the impeller turns at a high speed, the spoon blade will spoon the liquid quickly and throw the liquid decentralized powerfully to the liquid inlet pipe along the tangent direction. And the liquid is pumped out of the pump through the liquid outlet pipe. Compared with the sheet blade, the utility model can enhance the efficiency and save energy as the thrown liquid is in large quantity and powerful. The utility model is applicable for all kinds of liquid.

Description

Spoon formula liquid pump

Technical field

The utility model relates to a kind of liquid pump, particularly the impeller liquid pump that is driven by power engine.

Background technique

Existing impeller liquid pump generally comprises pump case, sheet impeller and pump shaft, liquid-in pipe and drain pipe.Power engine is by pump shaft impeller high speed rotating in pump case, after liquid enters pump case from liquid-in pipe, and high speed rotating together thereupon under the drive of impeller blade, and under action of centrifugal force, liquid is thrown away from drain pipe.Like this, impeller is high speed rotating constantly, and the liquid that enters the pump housing from liquid-in pipe is constantly thrown away from drain pipe again.The structure and the working principle of Here it is existing impeller liquid pump.The impeller of this sheet impeller liquid pump is little with the force feed effect to rising of liquid, and the whole efficiency of liquid pump is low, and power consumption is big.

Summary of the invention

It is big with the force feed effect to rising of liquid that the purpose of this utility model provides a kind of impeller, the high and energy-conservation spoon formula liquid pump of efficient.

The utility model comprises pump case, impeller and pump shaft thereof, liquid-in pipe and drain pipe, it is characterized in that:

Described pump case is that interior sky is that two circles intersect the housing that constitutes;

In the pump case admission chamber that is connected with liquid-in pipe one side, be provided with the impeller of blade, in the pump case retaining sap cavity of opposite side, be provided with the retaining liquid wheel that contains arc notch for the spoon shape;

Described drain pipe be located at empty circle intersections in two above, and communicating with the tangent place of admission chamber.

Described impeller and retaining liquid wheel, axle and the bearing by separately is bearing in two of pump case, and obtains power by the gear on the axle respectively respectively, and wherein one is fixedly connected with power machine output shaft.

The switched in opposite of described impeller and retaining liquid wheel, spoon shape blade wherein caters to corresponding with arc notch mutually.

The spoon shape liquid pump of said structure becomes the spoon shape with Blade Design, and the blade of the flowing fluid ratio sheet that can store is much more.Because retaining is provided with the water-blocking wheel with the impeller switched in opposite in the sap cavity, and the spoon leaf of impeller and arc breach that retaining liquid is taken turns cater to correspondingly mutually, makes both counter-rotatings become possibility.Retaining liquid wheel blocks most liquid of desiring to enter the retaining sap cavity, makes to enter that most liquid is in the admission chamber in the pump case the circular liquid bath of shape one between the impeller outside and inside pump casing.When impeller produces high speed rotating, the spoon leaf on it can be many and soon spoon and on last tangent direction, centrifugal is thrown on the drain pipe to the liquid that enters into admission chamber, pump outside the pump housing by drain pipe.The moment that part liquid is pumped out forms partial vacuum in liquid bath, air pressure is significantly less than the barometric pressure of outside, and under this action of pressure, the outer liquid of pump is drawn onto in the pump, constitutes circulation.The liquid that throws away from the spoon leaf is many and strong, compares with the blade of sheet, and efficient is improved widely, has saved the energy.Thereby achieve the goal.

Description of drawings

Fig. 1 is a plan structure schematic representation of the present utility model.

Fig. 2 is the structural representation that Fig. 1 analyses and observe along the A-A line.

Embodiment

As can be known, motor 1 rotates by the retaining liquid wheel 12 that its output shaft 2 drives in driving gear 3 and the pump case retaining sap cavity 11 in structural representation Fig. 2 that overlooks and analyse and observe along A-A shown in Figure 1.Driven gear 4 obtains power with driving gear 3 engagements, and the impeller 15 that drives in the pump case admission chamber 7 by its central shaft 5 rotates.Be connected with liquid inlet pipe 6 in admission chamber one side.The two ends of driven gear shaft 5 are bearing on the both sides of pump case by bearing and end cap 8 thereof.Pump case comprises that empty circle intersects admission chamber 7 and is provided with drain pipe 9 above retaining sap cavity 11, two chambeies 7 and 11 intersections in two.In like manner, end bearing and the end cap 10 thereof of the prolongation axle of motor 1 output shaft 2 by the two ends both sides that are bearing in pump case.Described motor 1 is one of power engine, and power engine comprises motor, diesel engine and petrol engine etc.

In Fig. 2, communicate in liquid-in pipe 6 and the admission chamber 7, be provided with impeller 15 by driven shaft 5 and bearing thereof and end cap 8 in the admission chamber 7, on the outer rim of impeller 5, be provided with the blade 16 of spoonful shape.On the tangent direction above the circular admission chamber 7, admission chamber 7 communicates with drain pipe 9.Retaining sap cavity 11 be circular, is provided with retaining liquid wheel 12 by driving shaft 2 and bearing thereof and end cap 10 this chamber in, and this is taken turns 12 outer rim and is provided with an arc notch 14, and it is relative that this breach 14 and a spoon leaf 16 cater to, and makes impeller 15 and keeps off liquid and take turns 11 backward rotation and become possibility.On retaining liquid wheel 12, be provided with 3 Reduction of Students' Study Load open-works 13.The spacing of circle is less than 1mm in the cylindrical of retaining liquid wheel 12 and the retaining sap cavity 11.In like manner, the round track that forms when even leaf 16 outer rims on the impeller 15 are being rotated, with the spacings of justifying in the admission chamber 7 also less than 1mm.Form a lead channel 17 between impeller 15 and admission chamber 7 inboards, make spoonful leaf 16 when rotating, arrive more liquid by spoon, and in rotation, on centrifugal direction, be sent in the drain pipe 9, outside the rear pump.

The working principle of this spoonful of formula liquid pump is: motor 1 or other power engine, drive driving gear 3 and 12 rotations of retaining liquid wheel by its output shaft 2, and also rotate by driven gear 4 and axle 5 impeller 15 thereof.In pump, impeller 15 and the switched in opposite of keeping off liquid wheel 12, the annular liquid flume 17 of liquid in liquid-in pipe 6 enters into admission chamber 7, the spoon leaf is in rotation, and spoon arrives a lot of liquid in the liquid bath 17, and on the superincumbent tangent direction, with spoon to feeding liquid under pressure in drain pipe 9, effectively outwards pump.When spoon leaf 16 forwards and keeps off liquid to and takes turns 12 intersections, arc notch 14 on the retaining liquid wheel 12 caters to relatively or gives in, retaining liquid wheel 12 has blocked in the spoon leaf 16 centrifugal and liquid that goes out and the liquid of desiring to pour in the retaining sap cavity make it to get back in the liquid bath effectively, thereby has improved the efficient of spoon liquid.Like this, the liquid that spoon goes out has the liquid that newly enters to replenish again, and circulation is continuous, and effectively and how the liquid that this pump can will be entered in the pump housing pump outside the pump, finishes the work of liquid pump.
