Description

A kind of air exhausting device of centrifugal pump
Technical field
The utility model belongs to wastewater treatment equipment technical field, is related to a kind of air exhausting device of centrifugal pump.
Background technology
Centrifugal pump is the capital equipment of water treatment system waste water lifting, for lifting, each process section waste water lifting, the dirt of intaking The water conservancy project equipment of the systems such as mud pump drainage.
Referring to Fig. 1, the impeller of current Centrifugal Pumps in China is arranged in pump case 1, and is fastened on pump shaft 2, and pump shaft 2 is by motor Directly drive.Pump case center has a fluid intake 3 to be connected with suction line 4.Liquid enters in pump through bottom valve 5 and suction line 4.Pump Liquid outlet 6 on shell is connected with discharge pipe 7.
Before centrifugation pump startup, the liquid conveyed is filled in pump case;After startup, impeller drives high-speed rotation, leaf by axle Liquid between piece also must be with rotation.Under the influence of centrifugal force, liquid is thrown to outer rim from impeller central and obtains energy, To leave impeller outer edge at a high speed into volute pump case.In spiral case, liquid slows down due to the gradually expansion of runner, and by part Kinetic energy is changed into static energy, finally flows into discharge line with higher pressure, delivering to needs place.Liquid is flowed to by impeller central During outer rim, certain vacuum is formd in impeller central, because the pressure of storage tank ullage is more than the pressure at pump intake, liquid Body is just by continuously press-in impeller.It can be seen that, as long as impeller is constantly rotated, liquid constantly will be inhaled into and discharge.
When pump case internal memory has air, less centrifugal force is produced because the density of the density ratio liquid of air is much smaller.From And, storage tank ullage is not enough in liquid press-in pump, i.e., centrifugal pump is without self-priming in storage tank with the pressure differential at Pump Suction Nozzle Ability, prevents centrifugal pump to be referred to as " air sinuses phenomenon " from conveying liquid, such a phenomenon.
The subject matter that current this device exists in actual use is:
1st, bottom valve foreign matters from being blocked, fouling and clogging cause to be difficult to be vented, it is impossible to lift liquid;
2nd, suction line fouling and clogging, causes bottom valve to be not closed completely and is difficult to be vented, it is impossible to lift liquid;
3rd, maintenance bottom valve must stop production, lower to bottom of pond maintenance;
4th, lifting maintenance must build inspection platform, and need to employ loop wheel machine cooperation;The cost of overhaul is high.
The content of the invention
In order to overcome the disadvantages mentioned above of prior art, the utility model provides a kind of air exhausting device of centrifugal pump, and it has knot Structure is simple, simple to operate, it is easy to maintenance the features such as, can effectively solve foreign matter and block up pump, spoil disposal;Cancel bottom valve, reduce the cost of overhaul With maintenance labor intensity;The probability that reduction employee overhauls to bottom of pond, improves work situation condition;Improve production efficiency;With compared with High practical value.
The utility model solves the technical scheme that its technical problem used:A kind of air exhausting device of centrifugal pump, including gas Exhaust outlet is set at the top of tank, gas tank, exhaust outlet is respectively provided on two sides with the water inlet being connected with gas tank and enters sewage mouth, enters sewage mouth It is connected with suction line, clean water outlet is provided between exhaust outlet and water inlet, the clean water outlet is connected with running water pipe, gas tank bottom sides The mouth of a river is set out, delivery port is connected with the connecting tube with filter screen, connecting tube is connected with pump advance water pipe;Gas tank bottom sets mud discharging mouth.
The exhaust outlet is equipped with flange and air bleeding valve.
The clean water outlet is equipped with flange and purge valve.
The delivery port is equipped with flange.
The mud discharging mouth assembly flange and valve, valve can be replaced by blind plate.
It is described enter sewage mouth be equipped with flange.
The gas tank is made using medium carbon steel.
Bearing support is provided with the gas tank lower end.
The beneficial effects of the utility model are:Foreign matter can effectively be solved and block up pump, spoil disposal;Cancel bottom valve, reduce the cost of overhaul With maintenance labor intensity;The probability that reduction employee overhauls to bottom of pond, improves work situation condition;Improve production efficiency;With compared with High practical value.
