摘要： The present invention is to suppress generation of cavitation in an impeller of a pump and disproportion of generation areas thereof by suppressing a secondary flow generated in a bent portion of a pump suction pipe. A pump suction pipe includes: a suction pipe outlet portion that is connected to an impeller suction port of a pump and is arranged in the up-and-down direction; a suction pipe inlet portion that is arranged in the lateral direction; and a suction pipe bent portion that connects the suction pipe outlet portion and the suction pipe inlet portion to each other and changes a flow from the lateral direction to the up-and-down direction. The distance from a reference point to an inner end of the suction pipe bent portion is monotonically increased from the upstream side to the downstream side on a vertical cross-section.

摘要： An inducer includes a hub having an inlet end and an outlet end. At least one full size blade has an inner edge is affixed to the hub and an outer edge. This full size blade extends rearwardly from the inlet end in a helical configuration. A partial shroud encloses a first length of the full size blade outer edge adjacent the inlet end. A second length of the full size blade outer edge that is adjacent to the outlet end is free of the partial shroud. It is within the scope of the disclosure to include short blades symmetrically offset from the two full size blades. These short blades have a short blade inner end affixed to the partial shroud and a short blade outer end extending from the partial shroud towards the hub, but terminating prior to reaching the hub.

摘要： A fan assembly includes a fan and a casing receiving the fan. The casing is formed by one-step injection molding and includes a base portion, a cover portion, a connection portion, and a plurality of anti-vibration members. The connection portion is formed by thermal-pressing and rotatably connects the cover portion and the base portion. The anti-vibration members are attached to the cover portion and the base portion and located between the fan and the cover portion and the base portion when the cover portion and the base portion are locked together to absorb vibration and prevent the transmission of the vibration to the casing.

摘要： The system and method is for the pumping of finely divided cellulose material to a continuous digester. The system has a concentric arrangement of pipes. A fluid (Liq) is added to a chamber formed between the pipes to establish a cylindrical film of fluid around a rod-shaped flow of cellulose material before the inlet to the pump. It is possible in this way to reduce the pressure drop in the lines, reduce wear in the pump, and ensure a maximal pressure build up in the pump.

摘要： Embodiments of the invention provide a method, device, and turbopump configured to suppress higher order cavitations at an inducer tip in a turbopump. An inducer having a tip is rotated, and a first flow is induced axially through the inducer at a first velocity. A second fluid flow is introduced toward a tip of the inducer substantially parallel to the first fluid flow at a second velocity that is greater than the first velocity, such that back flow through the tip of the inducer is reduced.

摘要： The present invention is a system (20) for controlling various fluid flows, e.g., secondary fluid flows including cavitating fluid flows, typically developed along the shroud line and usually in or around a leading edge (21) within a flow channel (22) of a compressor or pump impeller (23) and inducer/impeller (24). System (20) includes a plurality of devices for controlling various flow conditions. In one embodiment, system (20) includes a diffuser device (27) for stabilizing cavitating flows, a bypass device (28) for re-injecting flow upstream, and a flow control device (30) for selectively directing secondary fluid flow to either the diffuser device or the bypass device. In addition, at very high flow rates, bypass device (28) may also serve as a high-flow, forward-bypass device. Devices (27) and (28) form a pathway for secondary fluid flows, including cavitating flows, around a first portion (31) of a housing (32).

摘要： The present invention is a device (100) for at least partially stabilizing an unstable fluid flow within a flow channel (103) by capturing at least a portion of the unstable fluid within a vaneless diffuser having a diffuser slot (104). The present invention also includes maintaining and harnessing a substantial portion of the energy contained in the fluid as it flows through the diffuser in order to utilize the fluid to improve the condition of the flow field. An example of a beneficial use includes discharging the diffuser effluent into the flow at other points critical to instability, hence reducing the overall instability of the flow channel.
