Abstract
A specialty pump and heat exchange system having a fluid pump driven by a gear assembly. The fluid pump has a pump casing and an inboard head that form a fluid passageway when connected together. The gear assembly uses lubricant in the transmission and that lubricant is cooled by being pumped from the gear assembly through a lubricant passageway in the inboard head and then recycled back to the gear assembly for further use. In addition to cooling the lubricant, the system warms the fluid pump and/or fluid passing through the fluid pump.
Claims16
A centrifugal pump comprising:
- a casing in part defining a fluid passageway;
- and
- an inboard head connected to said casing and in part defining said fluid passageway;
- said inboard head having a common wall in part defining an oil passageway, said common wall separating said oil passageway from said fluid passageway.
A centrifugal pump comprising:
- a gearbox assembly;
- and
- a fluid pump comprising:
- a casing;
- an inboard head, where said casing and said inboard head define a fluid passageway of said fluid pump;
- and
- an oil supply port defined by said inboard head and through which said port is capable of receiving oil from said gearbox assembly.
A heat exchange system for cooling lubricant used in a gearbox configured to drive a centrifugal pump, said system comprising:
- a gearbox assembly;
- and
- a fluid pump connected with said gearbox assembly, said fluid pump comprising:
- a casing;
- an inboard head having a common wall in part defining a lubricant passageway within said inboard head;
- and
- an impeller, where said impeller and said common wall in part define a fluid passageway of said fluid pump.
