Description
Technical field
The present invention relates to field of fluid control, and in particular to a kind of without bottom valve centrifugation pump priming exhaust apparatus and its user
Method.
Background technology
Centrifugal pump (in addition to self priming pump) before activation will be water be filled in water pump and water inlet pipe, and otherwise water pump can not carry out
It pumps up water work；And be not discharged after centrifuging pump startup, it is not emptied often caused by air in pump, caused by water is not filled.
There are mainly two types of water-filling methods before existing centrifugation pump startup：It is one is assembly bottom valve water-filling, bottom valve is used
Check valve is mounted in the import of water inlet pipe, and the shortcomings that this method is that bottom valve head loss is larger, affects the device effect of water pump
Rate；Another kind is without bottom valve water-filling, the great advantage of this method be it is energy saving, relative to have the pumping plant of bottom valve can save energy 10%~
15%.
Common centrifugal pump without bottom valve water-filling method has：
1, vacuum water tank water-filling method：For not setting the small pumping station of bottom valve, vacuum water tank water-filling method can be used；Before starting mode of pump,
Water tank is first filled water to be sealed.After starting mode of pump, water pump is intake from vacuum tank, since cistern water level decline causes in water tank
Certain vacuum is formed, the water in intake pool will enter through water inlet pipe in water tank under atmospheric pressure, to form water
Cycle, so that water pump is started normal operation；The shortcomings that vacuum water tank water-filling method is to need repeatedly to observe vacuum in water filling process
Water tank avoids water-filling excessive to ensure water-filling situation in vacuum water tank, causes overflow phenomena, and process is relatively complicated, cannot be effective
Reduce operation intensity.
2, jet stream pump priming method：When driving pumping for water pump with diesel engine, the exhaust gas excluded using diesel engine is passed through and water
The ejector that communicates of pump top, carries out pumping water-filling, and in starting mode of pump, by the valve deck being connected with handle closing, exhaust gas is from penetrating
It flows device to spray, the air in pump is sucked out by connecting leg；Valve deck is opened after water-filling, control valve is closed；Jet stream pump priming
The shortcomings that method is that requirement floor treatment ability is big, submergence require it is high, and there are movable part inside jet pump, reliability compared with
It is low.
3, voluntarily diversion water-filling method：For the pump house using semi-immersed, (i.e. the pump crest level of water inlet pipe and water pump exists
Intake pool water surface pumping plant below), water can be self-introduced into water pump without artificial water；Voluntarily the shortcomings that diversion water-filling method
It is not make full use of the water absorbing capacity of water pump, while water pump Installation Elevation reduces, not only increases the excavated volume on basis, and
Operational management is also more inconvenient.
4, from outstanding diversion water-filling method：It is to pass through " aqueous vapor displacement " original using the gentle bulk density difference of water from outstanding diversion water-filling method
It manages to realize；This method can remove the bottom valve of water pump；The scavenging air receiver of appropriate container is installed on inlet pipeline, when water-filling, in advance
Scavenging air receiver topped up with water is given, is then sealed, scavenging air valve is then turned on, ventilation finishes, and closes scavenging air valve, some diversion is hanged
In water inlet pipe；It is repeated several times, water can be full of in water inlet pipe；It is to need repeated multiple times progress from the shortcomings that outstanding diversion water-filling method
Operation, operation intensity is big, and operating efficiency is poor.
5, vacuum pump priming method：It is more than the large and medium-sized pumping plant of 300mm for water inlet pipe diameter, or automation requires degree
Higher pumping plant, vacuum suction device are a kind of common water-filling equipment；Pass through vacuum pump constantly air-breathing and exhaust, you can will
Water pump is full of water；The shortcomings that vacuum pump priming method is that investment is larger, and cost is higher.
In conclusion without bottom valve centrifugation pump priming method is complicated, cost is higher, and part without bottom valve centrifugal pump uses
In there are movable part, reliability bottom, using effect is undesirable.
Invention content
The object of the present invention is to provide a kind of without bottom valve centrifugation pump priming rows simple in structure, esy to use, safe and reliable
Device of air and its application method.
To achieve the goals above, the technical scheme is that：
A kind of without bottom valve centrifuges pump priming exhaust apparatus, including vacuum water tank and the exhaust gear that is built in inside vacuum water tank,
The arrival end of the vacuum water tank is laid with tank inlet pipe, and the tank inlet pipe stretches in vacuum water tank, water tank water intake
It is 5~10 times of water tank water intake pipe diameter that pipe, which stretches to the length in vacuum water tank, water on the side wall of tank inlet pipe inserting end
It is flat to be outward extended with position-limiting tube；The exhaust gear includes air bag and is individually fixed in the gag lever post of the upper and lower end face of air bag, described
Air bag is partly wrapped in position-limiting tube and there are spacing, the gag lever post of the upper and lower end face of air bag to distinguish between the upper lower wall of position-limiting tube
It is pierced by from the tube wall up and down of position-limiting tube；The side wall of vacuum water tank offers water outlet, the water outlet of exhaust gear and vacuum water tank
Mouth is located at the opposite end of tank inlet pipe, and the lower part of vacuum water tank offers osculum, the row of being laid in the osculum

Further, the top of the vacuum water tank corresponds to the position of exhaust gear and is laid with gas vent, the exhaust spiral shell
Bolt and gas vent are threadedly coupled, in the end merging vacuum water tank of bleeder screw.
A kind of application method of without bottom valve centrifugation pump priming exhaust apparatus, includes the following steps：
The water inlet of tank inlet pipe when first used, before activation, is inserted into intake pool by step 1, without bottom valve centrifugal pump
Below face to be drawn water；
Step 2 back-outs bleeder screw on vacuum water tank, and processing, vacuum water is exhausted to vacuum water tank, without bottom valve centrifugal pump
The exhaust gear vertically laid in case is in active state；
Step 3, by tank inlet pipe, into vacuum water tank, water-filling, the increase with water level in vacuum water tank make at exhaust gear
In suspended state；
Water in step 4, vacuum water tank enters without bottom valve centrifugal pump through pump water inlet, when the gag lever post of air bag upper end is from vacuum
When the gas vent emersion of water tank upper, show that vacuum water tank water has been filled with, stops water-filling, bleeder screw is corresponded into air bag upper end
Gag lever post screws in gas vent, tightens bleeder screw, completes exhaust and water-filling operation for the first time；
Step 5 starts without bottom valve centrifugal pump, and without bottom valve centrifugal pump starts operation.
Further, further include：
When needing to carry out antifreeze processing to without bottom valve centrifugal pump, the drain plug in osculum is screwed out, vacuum can be discharged at this time
Remaining water in water tank, without bottom valve centrifugal pump and tank inlet pipe；When reusing without bottom valve centrifugal pump, step 1~5 are repeated.
Beneficial effects of the present invention are：
