Abstract
An injection device for injecting injection fluid (chemicals) into piping through which fluid flows, the injection device comprising: an injection line through which the injection fluid flows, the injection line being connected to the piping; an injection pump disposed on the injection line; an extrusion line connected downstream of the injection pump and upstream of a target portion for air removal on the injection line; and an extrusion pump for feeding extrusion fluid to the extrusion line, wherein a discharge capacity of the extrusion pump is greater than a discharge capacity of the injection pump.
