Title:
DIAPHRAGM PUMP USING RECIPROCATING MOTOR
Document Type and Number:
Japanese Patent JP2005098135
Kind Code:
A
Abstract:
To provide a diaphragm pump using a reciprocating motor for reducing noise, while accurately injecting the fixed volume.
This diaphragm pump uses the reciprocating motor for outputting a delivery quantity in response to a stroke quantity of a diaphragm 61 interlocking with reciprocating motion of an output shaft 51 of the reciprocating motor 30. The diaphragm pump has an electric current detecting part 81a for detecting an electric current flowing to the reciprocating motor 30, and a constant current control part 81b for controlling so that the electric current flowing to the reciprocating motor 30 detected by this electric current detecting part 81, becomes a constant current value.
