摘要： The invention relates to an improvement in nozzles/screen for fluid flow distribution/collection used In fluid flow distribution/collection used In fluid processing units. Improvement in conventions nozzle/screen comprises a flow restricting cylindrical body to have ring washer shape aperture control at inlet/outlet. The improved nozzle/screen comprises outer casing made of stacked flat rings with micro opening between said stacked ring providing uniform throughout its periphery. A central conduit having holes for flow of fluid entering through the said outer casing. The said conduit having means to regulate fluid flow.

摘要： A screen for intake of fluid. The screen includes parallel and spaced rods, filtration material, a fitting, and structural members. The rods may be distributed in a cylindrical configuration. The filtration material, which can be spirally wrapped wire, is disposed around the rods to define an interior volume. The fitting is disposed at an end of the rods and adjacent to the filtration material. Each structural member, which can be elongated bars, is interposed between adjacent rods. The structural members are welded to the adjacent rods, and the adjacent rods and the structural members are welded to the fitting to increase the effective weld area, the tensile strength of the connection, and potentially the overall strength of the screen. The screen may be used for a variety of fluids and installations, and is particularly suited to use in water wells.

摘要： A disc filter including a stack of apertured filter discs arranged about an axis, the stack having an outer surface and an inner surface and being mounted such that during backflush, individual discs are rotatable relative to adjacent discs about the axis and a disc cleaning assembly operative to rotate at least some of the discs about the axis relative to others of the discs, the disc cleaning assembly including at least one first fluid conduit for producing at least one outer liquid jet directed generally tangentially into engagement with the outer surface of the stack for rotationally driving the at least some of the discs about the axis relative to others of the discs and at least one second fluid conduit for producing at least one inner backflushing liquid jet directed into engagement with the inner surface of the stack.

摘要： A filter device is provided with an impeding member that impedes a flow of a fluid in a hollow portion of a filter element or a hollow portion of an outflow portion that communicates the hollow portion of the filter element and an exterior of a filter case. Further, a lid member that covers an upper end of the filter case includes an external flow path that communicates the hollow portion of the filter element to the exterior of the filter case.

摘要： A center tube for use with a filter element comprises a unitary body having a standpipe that defines a length along the longitudinal axis and a central flow passage and a plurality of radially extending flow fins attached to the standpipe, the flow fins spaced axially from one another along the standpipe to define radial flow channels, wherein each of the fins further defines a first aperture between the fin and the standpipe, the apertures together defining a first outer axial flow passage and the standpipe defines a rectangular shape.

摘要： A strainer body strainer body has a conical or bullet-like shape and includes a tip portion, a midsection, and a base portion. The midsection connects the tip portion to the base portion such that the tip portion, midsection, and base portion are aligned with one another along a straining axis defined by the strainer body. The strainer body includes a plurality of layers fused to one another and angled relative to the straining axis. The plurality of layers define flow passages that extend through the strainer body to impound particulate entrained in fluid traversing the strainer body through the flow passages of the strainer body.

摘要： A filter media in which larger corrugations are impressed or embossed onto media that has been previously corrugated with standard corrugations. This construction greatly increases the beam strength of a resulting pleat that allows the channels to remain open during processing into the pleated media, and prevents buckling of the media duping gathering on current pleating equipment. In addition, once the media is pleated, the larger corrugations or embossments, combined with the standard corrugations, create large channels for fluid flow from pleat tip to the base of the pleat.

摘要： A filtration element, which includes filtering tubes that are drilled with straight conical holes, and a central supporting tube and connecters/headcaps. The filtering tubes are arranged so that drilled surface portions face outwarded and the remaining undrilled surface portions are positioned adjacent to the central supporting tube. The filtration media can be made of tubular or flat metals or alloys. A plurality of filtration elements can be bundled using specially designed connectors to meet specific requirements for filtering of fine solid particles from liquids or gases or even liquid-gas-solid three phase. These elements can be used for various applications in filtration fields.

摘要： A return filter is provided in a tank, for removing bubbles from hydraulic oil before returning the hydraulic oil to the tank. A vortex forming portion that includes a spiral-shaped blade member is provided in an outflow portion that has a substantially cylindrical shape and communicates with a hollow portion of a filter element. Thus, a vortex forms in the hydraulic oil flowing through the outflow portion and bubbles contained in the hydraulic oil are collected.
