Description
Technical field
The utility model belongs to clear water transportation art, is that water pump can not realize self filling type water sucting mode specifically, and also do not bleed facility and tap water pressure to be poured water etc. and can be realized a kind of device of self-priming startup in situation.
Background technique
Water pump is the one conveying aqueous medium equipment that all trades and professions such as industrial and agricultural production all often use, when water pump absorbs water from pond, if adopt self filling type water sucting mode, can make all to be full of water in suction sleeve always, during starting mode of pump, eliminate the time of exhaust of pouring water, can put into operation rapidly, improve automation and the degree of reliability of starting mode of pump.But self filling type water sucting mode makes water pump axis absolute altitude lower than the working water level height in pond, this method is usually used in the building having basement, during layout, pumping station is arranged on basement, pond is arranged on basement pumping station side or outdoor underground, the working water level in pond, higher than water pump axis absolute altitude, makes all to be full of water in suction sleeve always.But in actual production and living facilities, most of pond generally all arranges or is present in the outside of building, be embedded in subsurface, cause the working water level in pond lower than water pump axis absolute altitude, water pump cannot realize self filling type water suction, at this moment, to pour water in suction sleeve before starting mode of pump must being solved by external force problem.
Overcome the above problems and usually at the suction sleeve end of water pump, water suction bottom valve is installed, namely a kind of safety check is installed, it ensures that current can only enter people's suction sleeve by pond and can not flow backwards, as long as be full of water in suction sleeve, although water pump axis absolute altitude is higher than the working water level in pond, under the effect of water suction bottom valve, the water in suction sleeve also can not flow into pond, can make all to be full of water in suction sleeve always, ensure that water pump can start automatically, rapidly.But water suction bottom valve is a kind of Reversal valve, and the time has been grown and will inevitably leak, the water in suction sleeve will slowly person who lives in exile pond, does not just have water and enters large quantity of air, still need manual priming before causing starting mode of pump in pipe.
For can water be full of in suction sleeve before guaranteeing starting mode of pump, following two kinds of modes are usually adopted to be solved:
1) before pumping line safety check, install a pipeline and be connected to outdoor municipal water supply pipe or other external water sources, supply water in starting mode of pump forward direction water pump suction pipe, the water that supplementary bottom valve is missed, makes to be full of water in suction sleeve; But the reliability of this water sucting mode, by the impact at outdoor water source, when without pressure outside water source or when cutting off the water for a long time at outdoor water source, just must rely on manual priming during starting mode of pump.
2) on pump sump pipeline, arrange vacuum pump, before starting mode of pump, vacuum pump first starts, and makes first to be full of water in water pump suction pipe, ensures that water pump starts automatically, rapidly.This water sucting mode needs perfect automatic control system to ensure that vacuum pump is prior to starting mode of pump, and cost is also high, and reliability is by the impact of automatic control system.
Chinese patent notification number CN201827091U, publication date: 2011.05.11, invention and created name is the self prime pump that need not add water, comprise the self prime pump body be made up of power section and pump, between pump and power section, be provided with a mainshaft gear, at power housing, the side of pump be provided with a gears to engage and disengage frame, described gears to engage and disengage frame assembles a driven gear, described driven gear drives a flexible axle, the small-sized water suction impeller that flexible axle drives its other end fixing; Be equipped with flexible axle sleeve pipe at flexible axle and small-sized water suction impeller outside, at the flexible shaft protecting tube end of small-sized water suction impeller side, one suction head be installed; Described flexible axle intermediate portion installs a water shutoff plug, and the flexible axle sleeve pipe at water shutoff plug place is connected by a threeway, another outlet connection one water pipe of threeway, the other end access water pump water filling hole of this water pipe.Need not toward water pump water filling hole filled with water before this model utility starts, as long as make mainshaft gear and driven gear be in startup work that engagement can complete self prime pump, but this model utility needs to increase a series of parts such as mainshaft gear, driven gear, gears to engage and disengage frame, flexible axle in the junction transformation of water pump and motor, transformation more complicated, reforming cost is higher, concrete impracticable when using.
