Dynamic valve control break-make, the votage control switch difference UNICOM's liquid-level switch and magnetic valve of the configuration of jet pump opposite side.The voltage-controlled pipeline
Seamless metal pipe is with suction channel, voltage-controlled pipeline one end connects the delivery port of centrifugal pump, and the other end connects votage control switch, by
This constitutes the observing and controlling passage that centrifugal pump exports hydraulic pressure.The external tapping of pump cover, the other end built in suction channel one end connection centrifugal pump
Linked up with the liquid-level switch inner chamber of aspirator, thus constitute centrifugal pump start-up period intake line and pump chamber is together sucked very
Empty passage.
As further improvement project, the compressed air pressure of the jet pump adapted is 0.65~0.8MPa.
As further improvement project, the liquid-level switch of the aspirator configuration is float-ball type structure, the center of ball float
At least 300mm on impeller horizontal central line.
The utility model compared with prior art, has the positive effect that：
1st, with aspirator with centrifugal pump group into self priming pump, structure is relatively easy and small volume, and makes easy；
2nd, the self priming pump being made significantly improves the ability of sucting under the effect of built-in jet pump, accomplishes before starting without artificial
Water filling, it is easy to operate, it is easy to accomplish Automated condtrol；
3rd, self-priming is quickly realized, greatly reduces capacity of returns in pump, so the way is high.
Brief description of the drawings
Fig. 1 is the utility model structural profile schematic diagram.
Fig. 2 is aspirator structural profile enlarged diagram in Fig. 1.
Embodiment
Below according to accompanying drawing and in conjunction with the embodiments, the utility model is described in further detail.
Autocontrol self-priming centrifugal pump shown in Fig. 1 is a kind of assembly equipment, and it includes centrifugal pump 1, aspirator 2, pressure
Keyholed back plate road 4 and suction channel 3.Centrifugal pump 1 therein is main element, because the present embodiment is applied on ship, it is necessary to selector
The marine vertical pump for closing marine equipment specification is used as matching pump.The water inlet 1.3 of centrifugal pump 1 and delivery port 1.1 discrete two being vertically arranged
Radially outer mouth upward is equipped with side, water inlet 1.3 and the flange of delivery port 1.1, pump case 1.2 also is provided with external tapping.This
Utility model overlaps the aspirator 2 being vertically arranged on the flange of water inlet 1.3 of centrifugal pump 1 with radially outer mouth, and this connection is done
The water inlet 1.3 of centrifugal pump is directly linked up to the inner chamber of aspirator 2.The aspirator 2 is one kind based on jet pump 2.2
Vaccum-pumping equipment, its placed coaxial of centrifugal pump 1 with side.Aspirator 2 in the present embodiment include liquid-level switch 2.1,
Jet pump 2.2, votage control switch 2.3, magnetic valve 2.4 and pneumatic operated valve 2.5.The power source of the jet pump 2.2 takes ship supply
The compressed air of pipeline, compressed air pressure used by the present embodiment is 0.65MPa.The upper end of the jet pump 2.2 placement spray of straight tube-like
Mouth 2.2.1, the nozzle 2.2.1 entrance points that compressed air is sprayed down are equipped with magnetic valve 2.4, are controlled according to operating mode magnetic valve 2.4
The flow or break-make of compressed air.Connecting pipe between the suction chamber side face port and liquid-level switch 2.1 of jet pump 2.2 is by gas
Dynamic valve 2.5 is controlled, the difference of the votage control switch 2.3 UNICOM liquid-level switch 2.1 and the structure of magnetic valve 2.4 of the configuration of the opposite side of jet pump 2.2
Into control passage.The voltage-controlled pipeline 4 and suction channel 3 are seamless metal pipe, the voltage-controlled one end of pipeline 4 connection centrifugal pump 1
Delivery port 1.1, other end connection votage control switch 2.3, thus constitutes the observing and controlling passage that centrifugal pump 1 exports hydraulic pressure.Suction channel 3 one
The external tapping of pump cover 1.2 built in end connection centrifugal pump 1, the inner chamber of liquid-level switch 2.1 of the other end and aspirator 2 is linked up, thus
Constitute the start-up period intake line of centrifugal pump 1 and pump chamber is together sucked the passage of vacuum.Disappear because the present embodiment is matched with ship
In anti-water system, the medium of suction is water, so the liquid-level switch 2.1 configured in aspirator 2 selects float-ball type structure most
Properly.In order to ensure the reliable self-priming of centrifugal pump 1, fast self-priming, ball float position therein necessarily be greater than when liquid-level switch 2.1 is installed
The impeller of supporting centrifugal pump 1, in case being full of water in the inner chamber of centrifugal pump 1 and intake line, the present embodiment is little because of specification, ball float
It is centrally located at 350mm on the impeller horizontal central line of centrifugal pump 1.
When the utility model is actually used, controls magnetic valve 2.4 to open first, compressed air is introduced by nozzle 2.2.1, this
Stage compression air opens rapidly pneumatic operated valve 2.5, and the intake line and pump chamber and aspirator 2 for making centrifugal pump 1 are connected.Into spray
The compressed air for penetrating pump 2.2 accelerates to spray through nozzle 2.2.1, and high velocity air forms flowing when expanding section by the way that jet pump 2.2 is mixed
Vent plug effect, facilitates the suction chamber formation negative pressure of jet pump 2.2, and water is filled into rapidly centrifugal pump 1 under atmospheric pressure
In intake line and pump chamber, liquid level is gradually risen until liquid-level switch 2.1, makes centrifugal pump when liquid level reaches precalculated position therewith
1 starts.Realize that pressure is just raised at delivery port 1.1 after self-priming once centrifugal pump 1, pressure reaches setting value at delivery port 1.1
When, liquid-level switch 2.1 is stopped compressed air by magnetic valve 2.4.Now, pneumatic operated valve 2.5 is also accordingly turned off so that aspirator
2 end with the water inlet 1.3 of centrifugal pump 1, only stay centrifugal pump 1 to run well.Because above-mentioned control action is by pressure
Or liquid level signal exports what is realized automatically, so be matched with ship's fire fighting water system, it is on duty without sending someone, meet modern ship
The supporting requirement of oceangoing ship.
