The utility model is characterized in that a return flow passage is connected between a liquid storage chamber and a suction chamber; an inlet and an outlet of the return flow passage are respectively positioned in the liquid storage chamber and the suction chamber. Having the advantages of original conception and simple and reasonable structure, the utility model can complete a self-sucking function by utilizing the inner structure of the pump body and has a good infusion function; so the utility model can achieve the feature of the internal mixed self-sucking pipeline pump.
Description
The utility model belongs to field of mechanical technique, relates to a kind of improvement technological scheme of self-priming pipeline pump structure.
Existing self-priming pipeline mounted pump has two kinds nothing more than, a kind of is the wheeled self-priming pipeline mounted pump of band vortex, a centrifugal impeller, a vortex wheel are arranged in such pump, and it is to rely on vortex wheel divided gas flow to finish self-absorption function, relies on centrifugal impeller to infuse then.But its complex structure, the life-span is short, and is bulky, the manufacture cost height, and there is technical difficulty in the design of high-power pump.Another kind is an external mixture type self-priming pipeline mounted pump, the separation of its gas liquid mixture is to rely on a centrifugal impeller to finish, its liquid in the gas-liquid separation process is back to the radially outlet port of pump centrifugal impeller by return port, and air and liquid mix at the impeller outer edge place and finishes self-absorption function.This pump is in self-priming and infusion process, and return port is unimpeded all the time, so efficient is lower, and structure is also unreasonable.
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, and self-priming pipeline pump liquid return-flow structure is improved, and a kind of internal-mixing self-priming pipeline mounted pump is provided.
Described internal-mixing self-priming pipeline mounted pump, motor is positioned on the casing, and casing is positioned on the pump housing, and pump inlet and pump discharge are located at the casing both sides respectively.Electric machine main shaft is connected with pump shaft by coupling, and constitutes rotary component by mechanical seal, axle sleeve, centrifugal impeller.Constitute the pump case parts by inlet port, casing, the pump housing, pump cover, mechanical sealing base.Casing, the pump housing cooperate the inner chamber that forms to have suction chamber, liquid storage room, gas-liquid separation chamber, it is characterized in that being connected the return flow line between liquid storage room and the suction chamber, and the return flow line import is arranged in the liquid storage room liquid level, and the return flow line outlet is positioned at the suction chamber place.
This internal-mixing self-priming pipeline mounted pump, novel, simple and reasonable, utilize the internal structure of pump own to finish self-absorption function, still have good transfusion function simultaneously, thereby realized internal-mixing self-priming pipeline mounted pump characteristic.
The utility model is described in further detail below in conjunction with Figure of description, provides embodiment simultaneously.
Fig. 1 is an internal-mixing self-priming pipeline pump structure schematic representation;
Fig. 2 is that the A of Fig. 1 schemes to throwing shape;
Fig. 3 is the sectional drawing of B-B casing in Fig. 1 structure;
The enlarged diagram that Fig. 4 lays for volute hydraulic model in Fig. 1 structure.
As shown in the figure, motor 18, casing 9, the pump housing 2 all cooperate with concavo-convex location centering each other, and pump inlet 12 and pump discharge 22 are located at casing 9 left and right sides respectively.Be connected by rigidity opposite opened coupling 17 between motor 18 main shafts and the pump shaft 16, centrifugal impeller 4 and corresponding impeller port ring 5 are installed in pump shaft 16 underparts, upwards are provided with axle sleeve 6, pump cover 8 and rolling bearing 7 successively.Pump cover 8 tops are provided with mechanical sealing base 25 and corresponding mechanical seal 26, seal leakage bolt 24.The cooling of mechanical seal 26 and lubricated be to finish by passage between rolling bearing 7 Internal and external cycles and mechanical seal liquid feeding passage 23, mechanical seal liquid feeding passage 23 is with the inner chamber UNICOM of liquid storage room 21 with mechanical sealing base 25, prevents that pump shaft 16 mechanical seal 26 under action of centrifugal force from damaging because of losing liquid.Tapping screw 1 is positioned at the minimum liquid level place of the pump housing 2, and liquid feeding screw 19 is positioned at the top of casing 9.Liquid storage room 21 is positioned under the pump inlet 12, and it is made up of the part inner chamber of casing 9 and the part inner chamber of the pump housing 2.Gas-liquid separation chamber 20 is located in the casing 9, and is positioned on the liquid storage room, is a space.Volute 27 is located in the pump housing 2, for level is disposed.Pressure chamber's diffusing tube 32 communicates with volute 27 and the pump housing 2 outlets, also disposes for level.The central authorities of cut water 31 between volute 27 I cross sections and VIII cross section angular regions, the radial clearance between it and the centrifugal impeller 4 is 0.5-2mm.Casing casting technique hole 30 is positioned at the outer end of the back side medium position of casing 9.Inlet port 13 cooperates with casing 9 imports, and fitting surface is the flange of a band ramp structure, so that unidirectional flap valve 14 convenient unlatchings.Unidirectional flap valve 14 is located at pump inlet 12 places, preferably is located between casing 9 imports and the inlet port 13.Its pattern is the structure that a door assembly with hinge and glass in right hand and left connects, and outer surface is a sealing material, and inner chamber is a rigid material.Suction chamber 15 communicates with pump inlet 12 and pump housing import, can liquid storage, but directly do not communicate with liquid storage room 21.Be connected by return flow line 28 between liquid storage room 21 and the suction chamber 15, return flow line import 11 is arranged in liquid storage room 21 liquid, and return flow line outlet 10 is positioned at suction chamber 15 places, and height and position is identical or be lower than return flow line import 11 positions.Be provided with control valve 29 in the middle of the return flow line 28.During this pump work, liquid in the pump housing is by the passage directive centrifugal impeller import 3 of centrifugal impeller 4, liquid storage room 21 and suction chamber 15, in centrifugal impeller 4, carry out sufficient gas-liquid mixed, and after pumping chamber diffusing tube 32 outlet be discharged to the gas-liquid separation chamber 20 of casing and carry out gas-liquid separation, at this moment the liquid level of suction chamber 15 descends, and the liquid of liquid storage room 21 just adds to suction chamber 15 by return flow line 28 with liquid return.The gas that reaches in the suction line in the process that so moves in circles, pump will drain, and pump has just been finished the self-priming process, and then pump just turns to the normal transfusion work that drops into automatically.Pump can closed control valve 29 in dropping into the normal infusion process, to improve the working efficiency of pump.
