Abstract
An improved pump system includes a booster turbine unit including a turbine mounted on the same shaft as the booster pump and utilizing a primary pump as the primary fluid power source. Various forms of turbine and booster pump may be used such that either the pressure or rate of flow from the primary pump may be increased substantially by a relatively simple and reliable system. The output of the primary pump may be flowed through the booster turbine including the booster pump or one fluid may be used as the same source and another as the pump system output. Various forms and designs are described.
Claims36
A booster system for use with a primary fluid power source in the form of a pump having an inlet and an outlet and including an impeller of a predetermined diameter and means continuously rotating said impeller at a predetermined speed to produce an output at a high efficiency based upon horsepower comprising:
- means forming a booster housing having an inlet port normally continuously receiving a major portion of the fluid from the outlet of said pump;
- shaft means rotatably mounted in said housing and including turbine means on one end thereof;
- inlet chamber means in said housing receiving said flow from said inlet port for driving said turbine means;
- booster pump means including fluid inlet means and fluid outlet means mounted on one end of said housing;
- said fluid outlet means of said booster pump means forming the principal fluid outlet of said booster system;
- said shaft including a portion thereof extending out of said housing toward said booster pump means;
- at least one booster pump impeller means mounted on the said portion of said shaft and driven by the fluid which passes through said turbine means;
- said housing at the other end including means to mount said housing for fluid communication with the inlet of the pump;
- means forming a low pressure section between said turbine and said pump mounting means,
- fluid input means communicating with said low pressure section whereby fluid entering said section is pumped by said pump to the turbine to drive the impeller of the booster pump means;
- said turbine being of a specific speed higher than that of the primary fluid power source pump to effect a speed increase in said booster pump means.
A pumping system for obtaining controlled flow rates and pressure comprising:
- primary pump means having an inlet and an outlet and including an impeller of a predetermined diameter and means continuously rotating said impeller at a predetermined speed to produce an output at a high efficiency based upon horsepower,
- booster turbine and pump means normally continuously receiving a major portion of the fluid from said primary pump means,
- said turbine booster and pump means including fluid outlet means forming the principal fluid output of said pumping system;
- said turbine booster and pump means including a housing,
- turbine means on one end of said shaft and pump impeller means on the other end of said shaft, whereby fluid flow through said turbine means is operative to effect rotation of said pump impeller means,
- housing means cooperating with said impeller to form a booster pump having an outlet,
- means forming a fluid outlet from said turbine means to said primary pump inlet means,
- means cooperating with said housing forming a fluid inlet means;
- and
- said turbine being of a specific speed higher than that of said primary pump means to effect a speed increase in said pump impeller means of said turbine booster and pump means.
