Rise and reset), the effect for generating the course of work has two o'clock: first is that response caused by diaphragm 2 has deformed bumper and absorbing shock work
With；Second is that the reaction force of the response deformation of diaphragm 2, makes the water into water chamber cavity 3 carry out pressure energy-storage；The work side of electromagnetic pump
Formula is intermittent water pumping, and diaphragm 2 is entirely pumping process formation continuous response deformation and energy storage, to reduce the change of flow fluctuation amount
Change, makes the flowing of the water continuous and stable in pipeline；Piping flow and pressure can keep an invariable value, later again via
The stream of apopore 1.4 enters the pipeline of valve deck 4, flows into subsequent water circuit system using the connector 9 of valve pocket 5.
In addition when not having water or water route to have air in electromagnetic pump body, electromagnetic pump dry pump, noise is very big and is difficult handle
Water pump comes out.When electromagnetic pump dry pump, the pump housing from air is stored by the gap between diaphragm 2 and valve body 1, be pumped into water chamber chamber
The air of body 3 equally generates pressure to diaphragm 2, and the air in 2 compression air chamber's cavity 6 of diaphragm generates certain deformation, water pump therewith
One end generates negative pressure, and the water of the other end can be pumped rapidly, while the air of water chamber cavity 3 is discharged to outside pipeline by water.
