Efficient sewage-draining energy-saving pump

Abstract

The invention provides an efficient sewage-draining energy-saving pump and belongs to sewage draining equipment. A water pumping shell, an upper magnet and a lower magnet are mounted in a buoyancy shell of the pump, the upper magnet and the lower magnet are located on the upper face and the lower face outside the water pumping shell respectively, and the water pumping shell is fixed in the buoyancy shell; a water outlet valve is fixed in a central hole of the water pumping shell, an iron core piston is arranged in the water pumping shell, a sealing cap seals a sewage inlet channel of a water inlet cavity, and a sealing plate seals a sewage inlet channel of an extrusion cavity; a limiting plug is fixed in a piston hole in the iron core piston, a sealing ball or a sealing cone is mounted in an inner taper hole of the iron core piston, and the lower end of the iron core piston is provided with an accommodating hole. The efficient water-draining energy-saving pump is compact in structure, small in vibration and high in electric energy utilization rate, has strong power and is suitable for pumping and draining sewage from a sewage treatment station, pumping and draining sewage from a sewage pool and pumping and draining sewage from a blocked sewage ditch; the pump floats on the sewage surface and can automatically ascend or descend along with changes of the sewage surface, and sediment and sludge cannot enter the efficient sewage-draining energy-saving pump; moreover, sewage can be drained through self-flowing.

Description

technical field [0001] The invention relates to a high-efficiency and energy-saving pump for sewage discharge in the field of sewage discharge. Background technique [0002] Traditionally, submersible pumps are used to discharge sewage in sewage pools and clogged sewage ditches, and blockage often occurs when sewage is discharged with submersible pumps. Therefore, we have designed a sewage pump that can float on the sewage surface. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency and energy-saving sewage pump that can float on the sewage surface to pump and discharge sewage and the manufacturing method thereof. [0004] In order to achieve the above purpose, the high-efficiency and energy-saving sewage pump of the present invention mainly includes a buoyancy shell, an upper magnet, a lower magnet, a pump water shell, a water inlet hole, a sealing ball or a sealing cone, a sealing plate, a sealing cap, an iron core pist...
