ELECTROMAGNETIC VIBRATING TYPE DIAPHRAGM PUMP WITH FUNCTION OF FLUID LEAKAGE PREVENTION TO ELECTROMAGNETIC SECTION

摘要

The object is to provide an electromagnetic vibrating diaphragm pump which is safe even when a diaphragm of a diaphragm pump is damaged and liquid or flammable gas penetrates an electromagnetic drive. An electromagnet coil container 7 containing electromagnet coils 4 in an airtight manner is further provided inside a casing 2, preventing fluid penetrated into the space outside the electromagnet coil container 7 from penetrating into the space inside the electromagnet coil container 7, and the electromagnet coil container 7 has a passage P formed for an oscillator 5 to move in reciprocation and the passage P is formed of a partition wall outside the container 7, the electromagnetic coil container is configured to prevent fluid penetrated into the space inside the passage P from penetrating into the space inside the electromagnet coil container 7.
