摘要:
A filter filters fluid flowing along an axial flow direction and includes a plurality of concentric cylindrical pleated filter elements having a common axis. A plurality of annular radial gaps between filter elements provide additional flow axially through the filter, providing equalized flow and reducing restriction. In further embodiments, a central filter element is concentrically surrounded by a cylindrical pleated outer filter element and provides additional flow axially therethrough.
摘要:
In general, this invention relates to supplemental coolant additive for use in cooling systems, for example, in diesel engine cooling systems. The supplemental coolant additive includes a C 4 -C 6 dicarboxylic acid, preferably adipic acid, and optionally a C 9 -C 12 aliphatic dicarboxylic acid an aromatic monocarboxylic acid, an aromatic dicarboxylic acid and salts of these acids. The supplemental coolant additive also can include a variety of other additives including molybdate salts, nitrate salts, nitrite salts, silicate salts and buffering agents. The supplemental coolant additive is preferably provided as a solid additive or a liquid concentrate. The supplemental coolant additive is preferably added to the liquid coolant over time to provide increased coolant life. Further the supplemental coolant additive provides enhanced anti-corrosion protection in cooling systems that include hard water.
摘要:
A self-driven centrifuge (20) for separating particulate matter out of a circulating liquid includes a base (29) having a pair of tangential jet nozzles (34) for generating the self-driven force for the centrifuge (20). Connected to the base is a centrifuge shell (28) which defines a hollow interior space. A hollow rotor hub (22) having a central axis of rotation is assembled to the base (29) and extends through the hollow interior space. A support plate (33) is positioned within the hollow interior space and, in cooperation with the rotor hub (22), defines an annular flow exit opening for the circulating liquid. Positioned within the hollow interior space is a separation vane module (21) which is constructed and arranged so as to extend around the rotor hub (22) and positioned so as to be supported by the support plate (33). The separation vane module (21) includes a plurality of axially-extending and spaced-apart separation vanes (38).
