Description
Technical field
The utility model relates to water pump fields, more particularly to a kind of self priming pump of high self-priming performance.
Background technique
The working principle of self priming pump is that water pump starting is preceding first fills water (or itself having water in pump case) in pump case.Starting
Impeller high speed rotation makes the water flow in impeller conduit to volute afterwards, and at this moment entrance forms vacuum, and the air in suction line enters pump
It is interior, and outer rim is reached through impeller conduit.
Due to the special construction of the self priming pump pump housing, after water pump stalling, there is a certain amount of water in the pump housing, after pump is again started up
Due to impeller turning effort, the air and water of suction line are sufficiently mixed, and are discharged to air-water separation chamber, air-water separation chamber top
Gas overflowing, the water of lower part returns to impeller, mixes again with the surplus air of suction line, in pump and suction line
Gas is all discharged, and completes self-priming, and normal pumping.
There are two main performance index for self priming centrifugal pump: self-priming time and suction lift.Self-priming time refers to self priming pump
The required time is worked normally from starting to start to；Suction lift refer to can complete self-priming relative to the maximum of entrance liquid level
Mounting height.
The self priming pump of the prior art all shows not satisfactory in two technical indicators, and self-priming time is longer, and self-priming is high
It spends lower, is mainly reflected in:
The self priming centrifugal pump of the prior art is due to using traditional centrifugal pump impeller structure (as shown in Figure 1), certainly
The gas-liquid mixed stage of suction centrifugal pump can form gas swirl on the entrance side of impeller blade, be unfavorable for gas discharge, thus
Self-priming time is longer, and suction lift is lower.
The self priming centrifugal pump self-priming time of the prior art is longer, and pump discharge reduces for a long time all without pressure after starting
The responsiveness of pump；
The self priming centrifugal pump suction lift of the prior art is lower, so adaptation to local conditions is unable to when installing pump, to side
Try to reduce the mounting height pumped, this can obviously increase the cost of the capital construction especially civil engineering of pump.
Current self-priming centrifugal pump does not adapt to requirement of the market for shorter self-priming time and larger suction lift thus,
Thus its scope of application is subject to certain restrictions.

Specific embodiment
The self priming pump of high self-priming performance as shown in Figure 2, impeller 2 and setting including the pump housing 1, in the pump housing 1 are pumping
Gas-liquid separation chamber 11 on body 1.With reference to Fig. 5 and Fig. 6, impeller 2 has several combined blades 29, each circle of combined blade 29
The arrangement of shape array.Interconnected runner is formed between adjacent combined blade 29.
With reference to Fig. 5 and Fig. 6, combined blade 29 includes front vane 24, rear blade 25 and arc plate 26,24 one end of front vane
In conjunction with one end of rear blade 25, the other end of front vane 24 and the other end of rear blade 25 are formed separately opening, make front vane
24 form " ox horn " shape with rear blade 25, and above-mentioned arc plate 26 is connected in the opening.Relative to front vane 24 and rear blade 25
For, arc plate 26 is further from the center of impeller 2, namely further from water inlet.Connection runner and mixing chamber are provided on rear blade 25
21 inlet hole 22 is provided with tap 23 on arc plate 26.
The rear blade 25 is compared to the centre of gyration for front vane 24 closer to impeller 2.Above-mentioned inlet hole 22
Position on rear blade 25 close to the centre of gyration is set, the radius of gyration is also smaller, and tap 23 is arranged on arc plate 26,
The radius of gyration is larger, is conducive to the sucking and discharge of gas-liquid mixture in this way.
After self priming pump stalling, the fluid reservoir 12 in the pump housing 1 has a certain amount of liquid, until Pump Suction Nozzle lower edge；Self-priming
It pumps after being again started up since 2 turning effort of impeller, the air and liquid of suction line are sufficiently mixed, mixed liquor a part passes through group
Runner between hing straps 29 is discharged to gas-liquid separation chamber 11, and another part then enters the mixing chamber 21 of combined blade 29, finally also
It is discharged to gas-liquid separation chamber 11；Mixed liquor is separated into liquids and gases in gas-liquid separation chamber 11 later, and gas overflowing is outer to pumping,
Liquid passes through return port 13 after falling and returns to impeller 2, mixes again with the surplus air of suction line, until pump and a suction line
Interior gas is all discharged, and completes self-priming, and normal pumping.
In embodiment, since combined blade 29 is provided with mixing chamber 21, inlet hole 22 and tap 23, self-priming pump startup
When, mixing chamber 21 is full of medium, and under the influence of centrifugal force, liquid radially does centrifugal movement, the slave tap such as piston
23 are forced out, and generate vacuum at inlet hole 22 at this time, and the liquid and air outside combined blade 29 are inhaled into mixing chamber 21, gas and
Liquid mixes well in mixing chamber 21, will not generate vortex delay, but be extruded quickly from tap 23, such impeller 2
The gas of entrance is endlessly discharged impeller 2, so that the self-priming performance of self priming centrifugal pump is effectively improved, when shortening self-priming
Between, increase maximum suction lift, by shortening self-priming time, to improve the responsiveness of pump, increases maximum suction lift, reduce pump
Capital construction especially civil engineering cost.
It is further preferred that the rim location of impeller 2 is arranged in arc plate 26, a part of flange arc is constituted.
