Abstract
The utility model provides a novel self-sucking pump, which is technically characterized in that an input end of a centrifugal pump is connected with an input end of an electric diaphragm pump, an electric starting and stopping device is respectively connected with a motor of the centrifugal pump and a motor of the electric diaphragm pump through cables, and an inlet pipe of the electric diaphragm pump is connected onto an inlet pipe of the centrifugal pump. Before start, an outlet valve of the centrifugal pump is closed firstly, and then the electric diaphragm pump is started and is used for sucking and discharging gas in the inlet pipe; and when sucked media reach the position of a liquid-level blockage valve of the electric diaphragm pump, the floating blockage valve can block the inlet of the electric diaphragm pump so that the media cannot enter the electric diaphragm pump, meanwhile, the media come into contact with a liquid-level float switch below the electric diaphragm pump, the float switch automatically closes the electric diaphragm pump, and thus, the float switch is automatically switched through an electric device so as to start the centrifugal pump to work. The novel self-sucking pump disclosed by the utility model has the advantage of overcoming long-standing defects of need of pump priming before pump starting, inconvenience in maintenance, liability to damage, ageing and corrosion, low self-sucking efficiency, complex structure and the like of various self-sucking pumps.
Description
Technical field
The utility model relates to a kind of new types of diaphragm formula self-priming pump that sucts under a kind of pump, particularly liquid.
Background technique
Put on self-priming pump under China's liquid at present and mainly contain following four kinds, and all have certain problem: the one, the liquid return hole is prone to stop up in the interior return flow type self-priming pump, the pump housing, causes self-priming to lose efficacy, and efficient is low, and self-priming time is long, is not suitable for the outdoor work in winter.The 2nd, no sealed type self-priming pump, efficient is low, and power consumption is big, and the interior liquid of pump overflows easily during stoppage in transit, and the self-priming performance reliability is low, is not suitable for the outdoor work in winter; The 3rd, Strong self priming pump, the vacuum system rate of fault is high, and bearing and driving gear are all fragile, manually keep off clutch, operation inconvenience, complex structure, inconvenient maintenance, the machine envelope needs outer flushing, end face inefficacys of dry grinding easily, the power consumption height, nonstandard pump safeguards that interchangeability is poor; The 4th, the turbine-type self-priming pump vacuumizes with the turbine blower fan, and gas is discharged through the impeller of high speed rotating, like flammable explosive gas, has potential safety hazard.
Summary of the invention
The purpose of the utility model is to the deficiency that exists in the above-mentioned technology, and a kind of novel reliable combined self-priming pump is provided, and can realize the complete machine pump on ground, and is easy to maintenance; Not fragile, the ability self-priming is inhaled the journey height, avoids dry grinding; Dielectric gas can never be to external leakage, and prolong working life greatly, can satisfy the needs of different operating mode dielectric gass fully; Efficient is high, and it is low to consume energy, energy-saving and emission-reduction.
The purpose of the utility model is achieved in that and comprises centrifugal pump, electric diaphragm pump, automatically controlled start and stop device.It is characterized in that input end vertical or horizontal centrifugal pump links to each other with the input end of electric diaphragm pump, automatically controlled start and stop device links to each other with the motor of centrifugal pump and the motor of electric diaphragm pump respectively through cable.The inlet duct of electric diaphragm pump is connected on the centrifugal pump intake piping, and the outer pipe of electric diaphragm pump is used for exhaust.Close the centrifugal pump outlet valve before the startup earlier; Main switch and control switch close; Press diaphragm pump start button electric diaphragm pump and start, diaphragm pump motor drives left barrier film and the one in front and one in back to-and-fro motion of right barrier film above the right ends plunger through speed-change gear box, about electric diaphragm pump in two pump chambers; Four non-return valves up and down are housed; The motion of barrier film causes the change of active chamber internal volume, the opening and closing that force four non-return valves to replace; Thereby gas is constantly sucked and discharges, medium entering diaphragm pump entrance pipe and centrifugal pump under the pressure of atmosphere under the liquid when the gas in the centrifugal pump entrance pipe is sucked by electric diaphragm pump and discharges.The stifled valve of ball float that the medium that when the medium that sucts touches the stifled valve of electric diaphragm pump ball float, is sucted floats is blocked the electric diaphragm pump inlet; Medium can not get into electric diaphragm pump; When the liquid level float ball switch below medium touches electric diaphragm pump, liquid level float ball switch output electrical signal is to circuit control box simultaneously, and centrifugal pump starts automatically in the time of the autostop of realization electric diaphragm pump; At this moment; Open the centrifugal pump outlet valve manually, centrifugal pump begins normally to carry medium under the liquid, has realized that the self-priming pump of electric diaphragm pump and centrifugal pump combination is put on the service behaviour of medium.
The beneficial effect of the utility model: 1, the complete machine pump on ground, easy to maintenance; 2, the pump shaft or the pump housing do not insert in the medium, and be not fragile; 3, do not need water, the ability self-priming; 4, inhale the journey height, can reach 7 meters; 5, medium is filled with pump and is just opened pump, avoids dry grinding; 6, barrier film will be transferred medium and gearing spare separately, and dielectric gas can never be to external leakage; 7, electric diaphragm pump itself does not have the axle envelope, and prolong working life greatly; 8, barrier film can be selected (being divided into neoprene, fluorine rubber, nitrile butadiene rubber, tetrafluoroethylene) according to different medium, can satisfy the needs of different operating mode dielectric gass fully; 9, high with similar function self-priming pump specific efficiency, it is low to consume energy, energy-saving and emission-reduction.
