Abstract
Pumps and fluid-handling devices for modifying at least one property of a fluid and related method comprise a compensation assembly including at least one biasing element to enable a hydraulic insert to move within a housing.
Claims20
A pump for modifying at least one property of a fluid, the pump comprising:
- an outer housing;
- pump stages positioned in the outer housing, each pump stage of the pump stages comprising:
- an impeller;
- and
- a diffuser at least partially housing the impeller;
- a shaft positioned in the outer housing, the impeller of each of the pump stages being coupled to the shaft, the shaft to rotate each impeller about an axis of the shaft to modify the at least one property of the fluid as the fluid travels through each of the pump stages;
- a crossover element positioned between a first set of the pump stages and a second set of the pump stages, the crossover element to enable fluid communication between the first set of the pump stages and the second set of the pump stages;
- and
- a compensation assembly positioned in the outer housing and comprising at least one biasing element to bias the compensation assembly into an initial position, the compensation assembly to enable the second set of the pump stages to move against a biasing force of the at least one biasing element within the outer housing in an axial direction along the axis of the shaft relative to at least one of the first set of the pump stages or the crossover element.

A fluid-handling device for modifying at least one property of a fluid, the device comprising:
- an outer housing;
- a first hydraulic insert positioned in the outer housing, the first hydraulic insert to modify the at least one property of the fluid as the fluid travels through one or more stages of the first hydraulic insert;
- a second hydraulic insert positioned in the outer housing in fluid communication with the first hydraulic insert, the second hydraulic insert to modify the at least one property of the fluid as the fluid travels through one or more additional stages of the second hydraulic insert;
- a crossover element positioned between the first hydraulic insert and the second hydraulic insert, the crossover element to enable fluid communication between the first hydraulic insert and the second hydraulic insert;
- and
- a compensation assembly positioned in the outer housing and comprising one or more biasing elements, the compensation assembly to enable the second hydraulic insert to move within the outer housing in an axial direction relative to the outer housing in response to a force applied to the second hydraulic insert that is sufficient to overcome a biasing force of the one or more biasing elements.
3 more elements
A method of preloading at least one hydraulic insert in a pump, the method comprising:
- positioning the at least one hydraulic insert within an outer housing of the pump;
- forcing the at least one hydraulic insert into a crossover element in the outer housing to preload at least one biasing element of a compensation assembly in the outer housing, the crossover element to enable fluid flow between the at least one hydraulic insert and another portion of the pump;
- and
- enclosing the at least one hydraulic insert in the outer housing with the at least one biasing element of the compensation assembly in a preloaded condition.
