Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
As seen from Figure 1: the present invention includes: motor 1 is fastened on the pump support 20 by screw 22, and pump case is made up of with water-pumping chamber 15 pump suction chamber 12 and is connected with pump support 20; The pump case left and right sides is provided with self-priming pump import 5 and pump discharge 19; Self-priming pump import 5 places are provided with ELECTROMAGNETIC VACUUM destructive valve 3, and the top of pump case pumping chamber 15 is provided with automatic control pressure vent 4; Impeller 11 links to each other with pump shaft 9 by connecting key 10, and impeller 11 peripheries are provided with stator formula air and liquid mixer 13, are provided with dividing plate 14 between the outer rim of stator formula air and liquid mixer 13 and the pump discharge 19, and pump shaft 9 links to each other with motor shaft 2 by coupling 21; Also comprise: a dynamic sealing device and a dynamic supercharging device; Pump shaft 9 is provided with dynamic sealing device with pump support 20 binding sites; The dynamic supercharging device is located between water-pumping chamber 15 and the self-priming pump import 5.
Described dynamic sealing device is made of jointly dynamic seal impeller 17 and the dynamic seal cavitys that are enclosed within outside the dynamic seal impeller 17; The dynamic seal cavity is made up of dynamic seal lid 16 and dynamic seal cover plate 18; Dynamic seal impeller 17 is connected with pump shaft 9 by driving key, and is fixed on the pump shaft by being threaded by set screw nut, and dynamic seal lid 16 is fixed on the dynamic seal cover plate 18 by attachment screw; The dynamic seal impeller is done high speed rotating in the dynamic seal cavity.
Described dynamic supercharging device is made of jointly pressure regulator valve 6, pressure inlet 7 and high pressure nozzle 8; The first half of pressure inlet 7 is between water-pumping chamber 15 and self-priming pump intake pipe, and its later half portion is positioned at self-priming pump intake pipe inside; Pressure regulator valve 6 is positioned at the first half of pressure inlet 7, and high pressure nozzle 8 is positioned at the latter half of of pressure inlet 7, its center line and intake pipe central lines.
Working principle of the present invention: fill liquid when using first in the pump, this moment, the suction line and the discharge tube the inside of pump-unit all were full of by air.Impeller is high speed rotating under driven by motor, produce vacuum at the impeller inlet place, the liquid of pump suction chamber is discharged from delivery side of pump by impeller, at this moment in the outer rim of impeller, air in the suction line mixes with water-pumping chamber stored liquid at high speed, forms gas-liquid mixture.This gas-liquid mixture is scraped and is discharged to the pump case pumping chamber by adjacent stator formula air and liquid mixer, dividing plate slows down the gas-liquid mixture of high speed rotating, further effectively separate at the indoor gas-liquid mixture of gas-liquid separation, air is discharged by pump discharge and automatic control pressure vent, liquid turns back to the pump case pumping chamber and enters impeller outer edge by deadweight, repeat to participate in gas-liquid mixed, separation, circulation overall process, the air in suction line is all drained.The self-priming pump suction line forms vacuum state, and the liquid under the barometric pressure effect in the suction pit is pressed into suction line, and pump is finished the self-priming process like this.This ELECTROMAGNETIC VACUUM destructive valve closes, open and the opening, stop synchronously of motor, guarantees that liquid is left in the pump chamber, realizes the purpose of " pump priming, lifelong self-priming ".
The working principle of " dynamic sealing device " among the present invention:
" dynamic sealing device " is made of jointly dynamic seal impeller and dynamic seal cavity, and the dynamic seal cavity is made up of dynamic seal lid and dynamic seal cover plate.Driven by motor dynamic seal impeller high speed rotating, the dynamic seal impeller produces the pumping effect, produces pumping pressure and comes fluid pressure in the ballast pump, realizes not having the dynamic seal of leakage purpose.
The working principle of " dynamic supercharging device " among the present invention:
" dynamic supercharging device " is made of jointly pressure regulator valve, pressure inlet and high pressure nozzle.When self-priming, by adjusting the aperture of pressure regulator valve, make the highly pressurised liquid in the water-pumping chamber arrive high pressure nozzle formation high-speed liquid by pressure inlet, this high-speed liquid can drive the interior air of suction line and be discharged to suction eye participation gas-liquid mixed rapidly, reaches the purpose that shortens self-priming time; After the self-priming pump normal infusion, by adjusting the aperture of pressure regulator valve, make the highly pressurised liquid in the water-pumping chamber arrive high pressure nozzle formation high-speed liquid by pressure inlet, this high-speed liquid fully mixes in the pump water inlet pipe with the interior liquid of suction line, and mixing material is discharged to the rapid diffusion velocity of pump suction chamber can be converted to the pressure energy.Pressurized liquid is absorbed by suction eye, has improved impeller anti-cavitation ability, has also just improved the self-priming height of self-priming pump, realizes the purpose of self-priming pump high suction depth.
" dynamic supercharging device " is to guarantee that self-priming pump improves the core technology of self-priming performance." dynamic supercharging device " guarantees that the liquid in the self-priming pump suction line is pressurized.Organic cooperation of above-mentioned just each constituent elements of dynamic sealing vertical self sucking pump with high suction lift, guaranteed that dynamic sealing vertical self sucking pump with high suction lift finishes liquid storage, gas-liquid mixed, separation, circuit self-priming overall process first, and reached the purpose that improves pump self-priming height and shorten self-priming time.
Having the following advantages among the present invention:
1, the axle envelope (mechanical seal/packing seal) of conventional pump has been got rid of in the application of " dynamic sealing device ", has thoroughly subdued ' run, drip, leak ' phenomenon, has the high characteristics of sealing reliability.
2, " dynamic sealing device " is non-contact seal, and working between the dynamic seal idol part does not have wearing and tearing, and its long service life avoids safeguarding, the axle envelope of pump becomes present long-lived part by traditional easily damaged parts.
3, the application of " dynamic supercharging device " has improved traditional self-priming pump self-priming performance, and when self-priming, it has the advantages that to shorten self-priming time: during normal infusion, it has the function that improves self-priming pump self-priming height simultaneously.
4, optimize the waterpower design, the use of high-efficiency and energy-saving type dynamic seal impeller has improved the efficient of complete machine greatly, has reduced the match power of motor, reaches the purpose of energy-conserving and environment-protective.
5, the design of Du Te stator formula air and liquid mixer has strengthened exhaust capacity, and dividing plate further effectively separates gas-liquid mixture, and the automatic/hand outlet valve has been accelerated degassing function again.
6, the application of ELECTROMAGNETIC VACUUM destructive valve has really realized " pump priming, lifelong self-priming ", is the highly integrated product of electromechanical appearance.
More than all embodiments only for the explanation the present invention usefulness, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or variation, so all technological schemes that are equal to also should belong to category of the present invention and should be limited by each claim.
