Definitions

  • the present invention relates generally to a hydraulic system.
  • the pump industry now has available computational fluid dynamic based machine design software that allows pumps to be designed to achieve various performance parameters.
  • the resultant designs require a high degree of dimensional precision to obtain the desired performance characteristics.
  • the challenge is to convert the complex computer design into actual components.
  • investment castings are often used.
  • Investment castings use metal molds that produce a wax pattern that in turn is used to make a ceramic mold.
  • the wax pattern is then heated so that the wax melts and is removed which leaves the ceramic mold.
  • the ceramic mold is then used to produce the metal parts for the pump.
  • the ceramic mold produces high quality castings having a good surface finish and dimensional accuracy.
  • investment casting tooling is expensive and is best suited to small size, mass produced parts.
  • the parameters of the pump need to match the performance characteristics that are desired. Flexibility in the design is important to achieving the performance objectives and this does not fit well with the use of mass produced parts. Accordingly, custom designed pumps are not a good fit with investment casting technology.
  • the internal casing components such as the volute and diffuser, can be machined from solid metal stock. Such machining can produce precise dimension control and a good surface finish.
  • the cross section of the volute is limited to parallel wall design configurations as the machining tools must be inserted and removed from the interior of the casing. There is little flexibility in the shape that can be machined under such restrictions. These restrictions on the shape of the internal chamber of the volute significantly limit the performance and efficiency characteristics of a pump produced with this technology.
  • Sand castings can also be used to produce pump casings.
  • sand casting does not work well for the internal casings of small pumps or turbines, as the surface finish produced is not smooth enough for good efficiency. Without the necessary level of efficiency such small pumps and turbines have a difficult time being a competitive product.
  • the cores that are used to create the internal voids such as the volute can shift during the molding or pouring process. This results in the void area being both axially and radially displaced from the desired position. Such shifting results in uneven flow entrances and a loss of efficiency for the pump.
  • the surface finish of such a cast pump casing is not as smooth as desired to obtain the best flow characteristics and efficiency.
  • the present invention overcomes the deficiencies of the prior art and allows the construction of pumps that maximize the efficiency and performance for the pump and allows for the cost effective production of unique one off design and construction of volute flow passages.
  • the present invention relates to improvements to the invention described in U.S. Patent Application Publication 2006/0013707 describing the use of removable components in the construction of hydraulic pumps, turbines and turbochargers to enable such devices to operate effectively over a range of operating conditions and to enable such devices to be modified in the field when operating conditions change.
  • the present invention includes improvements in the design of removable components in the construction of hydraulic pumps, turbines and turbochargers and more specifically relate to removably insertable components that define the internal hydraulic passageways of a turbocharger including volute inserts, vaned diffuser inserts, nozzle inserts, diffuser inserts, nozzle liners and diffuser liners.

  • the fluid is directed from the turbine volute to the impeller, which is caused to rotate by impulse and reaction effects of the fluid on the vanes of the turbine impeller.
  • the rotating turbine impellers power output is transmitted through the rotatable shaft to the pump impeller.
  • the turbine impeller decreases the pressure on the fluid that enters the turbine side of the hydraulic turbocharger and the fluid is discharged through discharge opening on the passageway.
  • fluid at low pressure enters the inlet of the passageway and enters the pump impeller.
  • the rotating impeller vanes cause the fluid to accelerate towards the periphery of the impeller.
  • the high velocity fluid exits the impeller to enter the volute, where the increasing flow area of the volute collects the impeller flow.
  • the fluid leaves the volute and then enters the pump discharge where increasing area produces a reduction in fluid velocity and increase in fluid pressure.
  • Means are provided for each of the removable components, either integrated into the design of the components themselves or separately attached to the components, to make it easier for operators to remove each of the removable, insertable components from the pump or hydraulic turbocharger.
