Chemical dropping injector is a section of pipe which is closed on an end and opened on the other end. Low density liquid is inside the dropping pipe and high density liquid is outside it. Under density difference, low density liquid flows from up hole and high density liquid flows from down hole. Balance between flowing in/out is maintained to assure that liquid chemical is continuously added in downhole. The quantity of dropping chemical is balanced. The configuration of the chemical dropping injector is simple and easy to be installed.
