Description
Technical field
The utility model relates to a kind of water pump, specifically a kind of electromagnetic plunge pump with back flash.
Background technique
Traditional plunger type water pump is due to the characteristic of self structure, cannot adapt in small-sized, microminiaturized product; Small-sized plunger type electromagnetic water pump is widely used in every field at present, particularly Miniature plunger type water pump is widely applied with the small and exquisite precision of its structure, it can be applied on coffee machine, steam raising plant, special application on range hood steam automatic flushing device.The principle of plunger type electromagnetic water pump is: plug core is not to utilize bent axle to drive, but under the effect of the restoring force of outside electromagnetic force and contained spring, carry out reciprocal operation, add the plug flowing to unidirectional block liquid in plug core, while making liquid flow through plug core, only have to water outlet direction and flow out, and can not flow out, thereby reach the function of pump water in the other direction.Wherein external electromagnetic field is provided by electromagnetic coil through one way rectifier by simple alternating current 220V, electromagnetic field only applies the pulling force (operation backward) of motion backward to plug core, thereby make plug core apply compressive force backward to inner spring, water is inhaled in pressure storehouse through plug core inner passage simultaneously, and after half-wave electromagnetic field effect is complete, plug core is because being subject to the effect of restoring force of contained spring, toward pressure storehouse internal operation, in storehouse, space wink speed reduces, water is forced out pressure storehouse, discharges to water outlet; In the time that water enters the suction sleeve of plunger pump inside, due to plunger pump core
Reciprocating in suction sleeve, and frequency and speed all very fast, reach in each second reciprocal 25 times, the distance of 0.15mm and only have an appointment in gap between pump core and tube wall, but the pump core of existing plunger type water pump is but cylindrical structure, in the time that pump core moves back and forth at a high speed between tube wall, water must be smooth and easy mobile back and forth between pump core and tube wall, water just can be minimum to the resistance of pump core, but the clearance distance between pump core and tube wall only has 0.15mm all too little, water flows and is difficult to back and forth at a high speed between this, therefore the resistance that pump core is back and forth moved is back and forth very large, will greatly consume so actual electromagnetic energy, reduce the efficiency of whole water pump, under Same Efficieney, water displacement reduces greatly, if but raised the efficiency with reducing the diameter of cylinder or increase the resistance that the clearance distance of caliber between increasing reduce water, can not, because the distance between pump core and inner magnetic guiding loop is less, the magnetic force of electromagnetic force on pump core just can be larger, electric energy converts kinetic energy to just can be larger, efficiency just can be higher, otherwise less, Efficiency Decreasing, magnetic loss is directly proportional to distance R 2, therefore can not raise the efficiency with reducing the diameter of cylinder or increase the method for caliber, therefore need to do further to improve to existing water pump.

Embodiment
Below in conjunction with accompanying drawing, the utility model is made to concrete further instruction.A kind of electromagnetic plunge pump with back flash, it comprises that pump cover 1, the pump housing 2, the pump housing 2 inside are provided with electromagnetic coil module 3, interior interting of electromagnetic coil module 3 is provided with drinking-water pipe 4, drinking-water pipe 4 two ends arrange respectively water intake 41 and water outlet 42, the inner spool 5 of installing of described drinking-water pipe 4, spool 5 can slidably reciprocate and make piston movement under the effect of electromagnetic coil module 3 in drinking-water pipe 4, it is characterized in that: described spool 5 surfaces offer some back flashes 51 that run through its rear and front end face.
Described back flash 51 cross sections are circular-arc, and uniform array is distributed in the surface of spool.
The described back flash 51 rectangular shapes in cross section, uniform array is distributed in the surface of spool.
Described back flash 51 cross sections are triangular shape, and uniform array is distributed in the surface of spool.
Poor being controlled between 0.2mm to 0.3mm of diameter of the diameter of described spool 5 and drinking-water pipe 4 inside.
Described spool 5 internal run-throughs are provided with water-guiding hole 52, and the outlet of water-guiding hole 52 is provided with safety check 53.
Working principle: be subject to the impact of electromagnetic force acting principle, coil and magnetic guiding loop 6, magnetic guiding loop 6 is less with the distance of valve core chamber, and the efficiency that coil acts on merit on spool is also just the highest, and the gap therefore dwindling is between the two to raise the efficiency the most direct way.Therefore just need to make the gap between spool and drinking-water pipe the smaller the better under the prerequisite that meets spool slip, but along with distance is between the two dwindled, frictional force between spool and drinking-water pipe is also just larger, therefore the fricative heat of spool can make electromagnetic coil be rapidly heated when pump working, impedance reduces, cause the power of water pump to decline, thereby cause the water-outlet quantity of water pump not greatly reduce, meanwhile, along with dwindling of spacing, the resistance of valve core movement is also just larger, therefore also need the power that strengthens coil could meet water pipe need of work, cause water pump power consumption to increase.For solving above-mentioned technical barrier, in the utility model, offer some back flashes that run through its rear and front end on the surface of spool, in spool sliding process, make pump water enter in back flash, make its effect of playing water lubrication, reduce the resistance to motion of water valve, make the free-moving while of spool, in improving the drainage efficiency of whole water pump, pump water can also absorb the heat that spool and electromagnetic coil produce, and avoids because of the electromagnetic coil power decline causing that heats up.Meanwhile, the gap in the utility model between spool and drinking-water pipe can be set to minimum clearance, thereby improves the working efficiency of water pump.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
