Description
Technical field
The utility model relates to industrial pump, refers more particularly to a kind of without sealing self-controlling self-priming pump.
Background technique
Self-priming pump is often used to the industries such as iron and steel, metallurgy, mine, electric power, petroleum and petrochemical industry, papermaking, sewage treatment.Pump is after normal starting, air in the liquid that suction chamber is deposited by impeller and suction line sucks together, liquid mixed gas is under the centrifugal action of impeller High Rotation Speed, gas-liquid separation chamber is thrown into through stator, because flow velocity reduces suddenly, gas is different from the proportion of liquid, lighter gas is separated and is discharged outside pump from mixed solution, degassed liquid reenters active chamber and again mixes with the air that impeller internal sucks from suction line, under the effect of the rotation of impeller, the pump housing is made to enter the certain degree of vacuum of interruption-forming very soon, thus reach the object of white suction.Because this pump has unique degassing function, therefore this pump can be carried the liquid containing gas and need not install bottom valve.This pump is furnished with electric air control valve, and during pump operation, control valve is closed, and realizes sealing; After shutdown; control valve is opened, and destroys the vacuum in suction line, prevents liquid many suction lines outflow because of cylinder suction effect of shutting down in rear pump chamber; make in pumping cylinder, to preserve enough liquid and continued self-priming process, thus achieve drainage first, permanent self-priming.
But; when the conveying of self-priming pump self-priming easily freeze maybe need insulation material medium time; after self-priming is shut down first and in startup operation process; material can freeze and solidify in pump chamber liquid storage room; blocking liquid storage room space; affect the unobstructed of pump inlet runner, therefore, common vertical self-sucking pump works and is difficult to start normal operation smoothly in northern cold season.
Summary of the invention
The purpose of this utility model solves above-mentioned Problems existing.
The utility model is achieved in that a kind of without sealing self-controlling self-priming pump, comprise the pump housing, liquid sucting port, second-stage pump body, motor, liquid outlet, axle, impeller, sencond stage impeller, sub-propeller, the output terminal of described motor is connected with axle by coupling, axle is disposed with sub-propeller, sencond stage impeller, impeller from top to bottom, impeller is fixed by hanging bolt, and sencond stage impeller is fixed by round nut A, and sub-propeller is fixed by round nut B; Described liquid sucting port upper end is connected with electrically-controlled valve, and liquid sucting port lower end is connected with taphole, and liquid sucting port is connected with the suction port of impeller, and impeller water outlet communicates with diversion chamber, and the bottom of diversion chamber is connected with deflector; Described liquid outlet outer installment has safety check, and liquid outlet right-hand member is provided with bleed valve, and liquid outlet communicates with the water outlet of sencond stage impeller, it is characterized in that: the axle excircle between described sencond stage impeller and impeller is provided with axle bush, is provided with muff in axle bush; Described deflector lower vertical is provided with guide plate, and guide plate right part is provided with heating pipe, and heating pipe is provided with air input joint and air outlet adapter.
Further, described heating pipe is spring-like.
Further, the material that described heating pipe, air outlet adapter, air input joint adopt is stainless steel.
