Description

Technical Field

[0001] The present invention relates to an electromagnetic pump, and particularly to an electromagnetic pump and a maintenance method thereof. Background Art

[0002] An electromagnetic diaphragm pump, abbreviated as an electromagnetic pump, is developed based on the principle that an electromagnet generates a magnetic force when energized to attract a magnet to perform reciprocating motion. It mainly consists of a diaphragm, a magnet, and an electromagnet. It can be used to extract gas for environmental detection.
