We just sat him down and asked what he was checking today.
Jet pumps create suction in a rather novel way. The pump is powered by an electric motor that drives an impeller, or centrifugal pump. The impeller moves water, called drive water, from the well through a narrow orifice, or jet, mounted in the housing in front of the impeller.
THE ELECTRIC LINEAR ACTUATOR. An electric linear actuator is a device that converts the rotational motion of a low voltage DC motor into linear motion â that is push and pull movements.This way it is possible to lift, adjust, tilt, push or pull heavy or hard-to-reach objects simply by pushing a button.HE ELECTRIC LINEAR ACTUATOR.
