Abstract

The invention discloses an electromagnetic diaphragm metering pump which comprises an electromagnetic pump body and a diaphragm pump head. The electromagnetic pump body comprises a winding frame, a coil winding and an iron core, the diaphragm pump head comprises a diaphragm pump cover, a middle mounting plate, a diaphragm pump base diaphragm and a soft plastic film, the diaphragm pump cover is provided with a liquid incoming joint and a liquid outgoing joint, the middle mounting plate is provided with a first through hole and a second through hole, the soft plastic film is provided with a first movable valve piece and a second movable valve piece, the middle mounting plate is provided with a first avoiding cavity at a liquid inlet of the first through hole, and the diaphragm pump cover is provided with a second avoiding cavity at a liquid inlet of a liquid outgoing hole. During liquid incoming, the iron core drives a diaphragm to move downwards, liquid enters a hydraulic cavity through a liquid incoming hole and the first through hole, and electrification time of the coil winding can guarantee the liquid with consistency of 10000mpa.s to be filled in a hydraulic chamber; during liquid outgoing, the liquid is discharged through the second through hole and the liquid outgoing hole. Consequently, the electromagnetic diaphragm metering pump can generate identical flow aiming at the liquid different in consistency.

Description

technical field [0001] The invention relates to the technical field of electromagnetic pumps, in particular to an electromagnetic diaphragm quantitative pump. Background technique [0002] In general liquid pumps, such as electromagnetic pumps, diaphragm pumps, impeller pumps and gear pumps, the same flow rate cannot be generated for liquids of different consistency. The system is a fixed frequency, and the flow rate depends on the pressure difference, and one of the determinants of the pressure difference is the consistency, and the consistency of the same liquid depends on different temperatures; And change. [0003] For example, for fully automatic washing machines, during the laundry process, different laundry detergents, softeners, and disinfectants are required to be injected into the washing tub through liquid pumps for cleaning. Among them, fully automatic washing machines are mainly determined by feeling the amount of clothes. The injection volume of the above-men...
