A fluid shunt system (1, 4) includes a filter (10, 41) including an accommodation chamber (17), an inlet (132), a first outlet (142) and a second outlet (152) in communication with the accommodation chamber (17) and a filter element (16) mounted in the accommodation chamber (17) and aimed at the first outlet (142), a shunt device (20, 42) connected to the filter (10, 41) and defining a first flow path (211) and a second flow path (221) in communication with the first flow path (211) and the second outlet (152), and a water pump (30, 43) connected to the first outlet (142) of the filter (10, 41) and the first flow path (211) of the shunt device (20, 42).
摘要:
This disclosure is to an apparatus and method for increasing the ability of centrifugal compressors or expanders to handle multiphase fluids with increased liquid content by passing the fluid through a slug suppressor and/or an atomizing device prior to compression or expansion.
摘要:
A method of storing water by restraining at least one flexible storage reservoir in a submerged position within a body of salt water; establishing a terrestrial intake in fluid communication with the flexible storage reservoir; and establishing a terrestrial outlet in fluid communication with the flexible storage reservoir for the release of stored water.

A system comprises a rotary machine, a sensor and a processor. The rotary machine has a component that operates on a fluid. The sensor senses pressure in the fluid. The processor generates a diagnostic indicative of wear on the component, based on process noise on the pressure.

Based on the Hazen-Williams approximate expression, an approximate expression computing unit (24) computes daily data acquired by a data acquisition unit (21) which captures, at a constant period, flow rate data and pressure data respectively transmitted from one flow meter which measures the inflow of purified water flowing from a distributing reservoir into a water distribution pipeline network and one pressure meter which measures a pressure in a pipeline at one proper position in the water distribution pipeline network. The approximate expression computing unit (24) also stores a total virtual pipeline extension and a flow rate correction coefficient for each day, which are obtained by using the least squares method, as parameters in a database (25), and computes a pressure value on the basis of the flow rate data and pressure data acquired at a constant period by an online pressure detection unit (26) and a data acquisition means (21) by using the parameters. The approximate expression computing unit supplies this pressure value and an actually measured pressure value to a display device (27) to express/process the values as a QH curve based on a flow rate (Q) and a water head (H), and displays the correlation between the inflow and the water head in the water distribution pipeline network as a graph of the QH curve.
摘要:
An internal blow out preventer is provided that includes a ball valve including a tubular assembly having a central passageway with upper and lower seats mounted therein. A ball is rotatably received between the upper and lower seats and includes an external surface and a central opening, wherein the central opening includes an undercut. A protective coating is applied to both the external surface and the undercut of the ball.
摘要:
A multicomponent fluid composition monitoring and compositional control system, in which a component analysis is effected by titration or other analytical procedure, for one or more components of interest, and a computational means then is employed to determine and responsively adjust the relative amount or proportion of the one or more components in the multicomponent fluid composition, to maintain a predetermined compositional character of the multicomponent fluid composition. The system (10) is usefully employed in semiconductor manufacturing photoresist and post-etch residue removal, in which the cleaning medium is a semi-aqueous solvent composition, and water is the monitored and responsively adjusted component.
摘要:
Fluid-flow control apparatus and method by which magnetically-positionable elements (23) within a rigid body (9) can be externally manipulated using controlling source of magnetic flux (39). The relative attractive forces which bias internal magnetic elements (29, 31) into normally-closed sealing engagement are substantially altered by repositioning the magnetic elements in response to the controlling magnet flux (39). Complete sealing or isolation against back flow through the valve under conditions of net positive outlet pressure is inhibited by the internal double-acting sealing elements (23, 24) which respond in unified manner to the controlling magnetic flux (39).
摘要:
The method of controlling operation of a plurality of fixtures comprises the steps of establishing a maximum fluid flow rate and determining which of the fixtures requires operation. A determination is then made of the fluid flow rate of the fixture requiring operation and calculation is made of whether operation of the fixture requiring operation will cause the maximum flow rate to be exceeded. The fixture requiring operation is caused to operate if the maximum flow rate will not be exceeded and is prevented from operating if the maximum flow rate will be exceeded.
