ABSTRACT:
A hydraulic turbine mounted in-line between a gas production facility and the inlet of the sales lines for boosting pressure sufficiently to insert natural gas from the production facility into the sales line when the sale line pressure is at a high level. The turbine includes a compact turbine pump having several stages of compression with each compression stage including a 15-horse power motor that drives a hydraulic pump. A variable speed control is attached to the motor to allow the user to control the speed of the pump. Each pump stage has its own hydraulic motor that drives a turbine blade inside an enclosure. Pressure at each stage is controlled by means of an adjustable vane that has a stationary plate with a succession of fixed openings. The stationary plate is in face to face contact with a moving plate of similar design. The moving plate rotates at the center and may be adjusted by means of an elongated bolt assembly which adjusts the moving plate clockwise or counterclockwise. This action increases or decreases the size of the opening thus controlling pressure inside the particular stage.
