When pump drainage sewage, conveying sewage pipeline outlet lower than be fixed on pump dirt shell lower end inlet opening place Slag filter on water inlet time, when the head of the sewage exported by pump water arrives the outlet of the pipeline of conveying sewage, under siphonage, be arranged in blowoff valve seal cone or ball sealer is output the suction of sewage and pulls and the up passage opening out sewage that separates with internal taper hole, the passage entering sewage entering extrusion chamber opened by seal cone or the ball sealer that are arranged on the internal taper hole in ferrite core piston under the pulling of the suction of the sewage of output, the passage entering sewage entering intake antrum opened by the watertight shrouding of crossing protruding on platform being arranged in pump dirt shell under the pulling of the suction of the sewage of output, the passage of whole pump water has reformed into the passage of gravity flow, just can self-flowing pastefill sewage after closing power supply.

In order to ensure environmental protection and energy saving sewage pump drainage pump can normal operation, control circuit has electronic remote controller, adopts electronic remote controller to control being switched on and off of power-on circuit of field controller；Control circuit does not have electronic remote controller, adopts the contactor being connected with insulated electric conductor to control being switched on and off of the power-on circuit of field controller.

In order to ensure that protective cover can be protected the coil of upper Magnet and lower magnet without damage and keeps the shape of protective cover, the interior intracavity manufacture at protective cover has the skeleton of support.

Not having mud and mud to ensure to enter in the sewage in sewage pump, the lower end in the floating chamber of annular makes water inlet maintain a certain distance with the bottom for the treatment of tank or the bottom of detention tank lower than the water inlet of Slag filter.

Keeping shape to ensure the floating chamber of annular can produce enough buoyancy and be not easy deformation, the interior intracavity manufacture in the floating chamber of annular has the skeleton of support.

In order to enable to be subject to the sewage in the intake antrum in magnetic piston driving pump dirt shell to enter in extrusion chamber, the electromagnetic field that lower magnet produces is adopted to be moved down, by magnetic piston, the power sewage in intake antrum being clamp-oned extrusion chamber as pulling.

During use, being placed in the sewage for the treatment of tank and in the sewage of detention tank by floating for the annular of dredge pump chamber, the water inlet of Slag filter gos deep in sewage；Not having remote control unit, directly connect the circuit that the contactor being connected with insulated electric conductor is connected with field controller, field controller is connected the power-on circuit of upper Magnet and lower magnet and is produced electromagnetic field；Having remote control unit, press the starting button of remote controller switch, electronic remote controller receives the power-on circuit connecting field controller after starting signal, and field controller is connected the power-on circuit of the upper Magnet of circulation connection and lower magnet and produced electromagnetic field；When upper Magnet produces electromagnetic field, the captivation of electromagnetic field pulls and is moved up by magnetic piston, when being started up by magnetic piston, it is arranged on by the ball sealer on the internal taper hole in magnetic piston or seals the passage boring descending return under the effect of the gravity of self and close sewage entrance extrusion chamber；When by magnetic piston stroking upward, the sewage in extrusion chamber is made to create pressure by the up of magnetic piston, there is the sewage of pressure to promote ball sealer from the internal taper hole that the endoporus of the sealed end of blowoff valve lower end enters in blowoff valve or to seal cone up and open the sealing passage of blowoff valve, make the sewage in extrusion chamber enter in blowdown pipe network after blowoff valve or in the pipeline of conveying sewage；By magnetic piston when up, also made to create in intake antrum pull of vacuum by magnetic piston, watertight shrouding was moved in pull of vacuum suction made the annular sealing surface of watertight shrouding and protrusion platform separate, sewage enters from the water inlet of Slag filter after filtering in Slag filter and to enter into protrusion platform through inlet opening from apopore again, then through cross on watertight shrouding by hole enter in pump dirt shell by the intake antrum below magnetic piston.

When being moved into place by magnetic piston stroking upward, the power-on circuit of the upper Magnet of field controller disconnection is followed by the power-on circuit of catharsis Magnet, and the electromagnetic field of upper Magnet disappears, and the electromagnetic field that lower magnet produces pulls by magnetic descent of piston；When being started descending by magnetic piston, be arranged in pump dirt shell lower end protrude on platform upper surface to cross watertight shrouding descending and close the passage entering sewage that enters intake antrum under the effect of self gravitation, ball sealer in blowoff valve or seal cone inner conical surface of descending return and sealed waste discharge valve under the effect of the gravity of self, has cut off the exhalant canal of extrusion chamber；By magnetic piston when descending, it is forced into the sewage in intake antrum by magnetic piston and makes sewage produce internal pressure, have the sewage of pressure from entered into by the limbers in magnetic piston upwards washed open the ball sealer sealed with internal taper hole by the internal taper hole in magnetic piston or seal cone displacement after continue up, enter in extrusion chamber behind the limbers in fixing plug.

By magnetic piston under the gravitation of the electromagnetic field that lower magnet produces pulls descending put in place time, it is arranged on by the ball sealer on the inner conical surface in magnetic piston or seals cone descending inner conical surface under the effect of the gravity of self and shut and make sewage not return intake antrum, now, field controller is connected again the power-on circuit of Magnet and is again produced electromagnetic field and pull by magnetic piston stroking upward；What so circulate is switched on and off circuit, make the electromagnetic field that Magnet produces pull and pulled by magnetic descent of piston by magnetic piston stroking upward and the electromagnetic field allowing lower magnet produce, constantly from treatment tank or sewage detention tank pumps out sewage and is transported in blowdown pipe network or in the pipeline of conveying sewage, and the sewage extracted there is no mud and mud；In the process of pump drainage sewage, the floating chamber of annular changes automatically with the change of the water surface.
