Abstract:
1. A system for injecting an injection fluid into a pipeline at a remote location, the injection fluid being stored within a storage tank at the remote location, the system comprising: an injection pump for injecting a selected amount of the injection fluid into the pipeline with each pump stroke; a timer for sequencing stroke initiation of the injection pump at a selected time interval; a control valve for controlling flow of pressurized fluid to power the injection pump; a controller for controlling operation of the control valve; an electric motor responsive to the controller for rotating a motor shaft and a cam rotated by the motor shaft; a battery for powering the motor and the timer; a sensor for initiating activation of the motor in response to a sensed pipeline condition; and the control valve operative in response to the rotational position of the cam to control opening and closing of the control valve.
