Description

One kind is without sealing self-controlling self-priming pump
Technical field
The present invention relates to industrial pump, more particularly to one kind is without sealing self-controlling self-priming pump.
Background technology
Self priming pump is commonly used for the industries such as steel, metallurgy, mine, electric power, petroleum and petrochemical industry, papermaking, sewage disposal.Pump is just After often starting, the air in liquid and suction line that impeller is deposited suction room sucks together, and liquid mixed gas is in impeller Under high-speed rotating centrifugal force effect, gas-liquid separation chamber is thrown into through guide vane, since flow velocity reduces suddenly, the proportion of gas and liquid Difference, lighter gas are separated from mixed liquor and are discharged outside pump, and the liquid of degassing reenters working chamber and impeller The air that inside is sucked from suction line mixes again, under the action of the rotation of impeller, pump housing entrance is formed one quickly Fixed vacuum, so as to achieve the purpose that white suction.Since the pump has unique degassing function, which can convey containing gas The liquid of body simultaneously need not installation bottom valve.The pump is furnished with electric air control valve, and during pump operation, control valve is closed, and realizes sealing;Stop After machine, control valve is opened, and destroys the vacuum in suction line, prevents the liquid after shutting down in pump chamber is many because of cylinder suction effect from inhaling Enter pipeline outflow, make to preserve enough liquid in pumping cylinder to continue to complete self-priming process, it is achieved thereby that drainage first, it is permanent from Inhale.
However, when the conveying of self priming pump self-priming easily freezes or need to keep the temperature material medium, after self-priming is shut down first and startup is transported During turning, material can freeze solidification in pump chamber fluid reservoir, and blocking fluid reservoir space, influences the unobstructed of pump inlet runner, because This, it is difficult smoothly to start normal operation that common vertical self-sucking pump works in northern cold season.
The content of the invention
Present invention aim to address above-mentioned problem.
What the present invention was realized in:One kind is without sealing self-controlling self-priming pump, including the pump housing, liquid sucting port, second-stage pump body, electricity Machine, liquid outlet, axis, impeller, sencond stage impeller, accessory impeller, the output terminal of the motor are connected with axis by shaft coupling, and axis is from upper Accessory impeller, sencond stage impeller, impeller are disposed with, impeller is fixed by hanging bolt, and sencond stage impeller is consolidated by round nut A Fixed, accessory impeller is fixed by round nut B;The liquid sucting port upper end is connected with electrically-controlled valve, and liquid sucting port lower end is connected with taphole, The suction inlet of liquid sucting port and impeller connects, and impeller water outlet is communicated with diversion chamber, and the bottom of diversion chamber is connected with baffle;It is described Liquid outlet outside be provided with check-valves, liquid outlet right end is provided with vent valve, and liquid outlet is communicated with the water outlet of sencond stage impeller, It is characterized in that:Axis excircle between the sencond stage impeller and impeller is provided with axle bush, and neck bush is provided with axle bush;Institute The baffle lower vertical stated is provided with deflector, and deflector right part is provided with heating tube, heating tube be provided with inlet suction port and Air outlet adapter.
Further, the heating tube is spring-like.
Further, the material that the heating tube, air outlet adapter, inlet suction port use is stainless steel.
The reliable, convenient disassembly of the present invention, be easily installed, when working northern cold season, by heating tube Be passed through steam or hot water preheated, can eliminate medium because solidification freeze and caused by block, so as to fulfill self priming pump to material Smooth self-priming conveying.
