Various embodiments include an exemplary design of an apparatus and related process to reduce or eliminate de-gassing from a liquid precursor during dispensing of the liquid precursor under vacuum. In one embodiment, the apparatus includes a liquid-flow controller configured to be coupled to a liquid-supply vessel containing the liquid precursor, and at least one valve hydraulically coupled downstream of and to the liquid-flow controller by a liquid line. The at least one valve is to be opened and closed to maintain a minimum pressure that is sufficiently high enough to reduce or prevent degassing of the liquid precursor throughout the liquid line. An atomizer is hydraulically coupled downstream of and to the at least one valve. The atomizer can produce droplets of the liquid precursor and is further to be coupled on a downstream side to a vacuum source. Other methods and apparatuses are disclosed.

The air/oil separator uses a multi-chambered reservoir tank, which is divided into four separate internal chambers. The discharge oil passes sequentially through the chambers within the separator progressively separating and collecting the liquid oil from the discharge. The separator has an elongated reservoir chamber and three additional chambers, a deflector chamber, a screen chamber and a filter chamber located over the reservoir chamber. The separator includes two removable diffuser plates suspended within the reservoir chamber. The separator includes a replaceable screen separating the reservoir and screen chambers and filter element mounted within the filter chamber. Discharged oil enters the separator through a side oriented inlet port into the deflector chamber. The discharge oil is directed against an internal deflector wall within the deflector chamber that redirects the flow radially before falling vertically into the main reservoir chamber below.

The invention relates to devices for purifying hydraulic and dielectric fluids (oils and fuels) of mechanical impurities and dissolved and dispersed water. It could be used in any fields where clean and contaminated fluids are used. The apparatus for reclaiming hydraulic and dielectric fluids comprises a vacuum tank with an atomizer, a vacuum pump, a dielectric fluid feed pump and dielectric fluid removal pump, all of said pumps being connected to the tank by pipes, and an electric filter, wherein the atomizer is disposed in the lower part of the vacuum tank, is arranged vertically with a spray member oriented upward and consists of a T fitting with a lower inlet for fluid and with a lateral inlet for air, a mixing chamber disposed above the T fitting, and a spray member with a nozzle, said spray member being disposed above the mixing chamber, and the electric filter comprises a housing with an inlet pipe and outlet pipe, a high-voltage power supply, a composite unit disposed inside the housing and consisting of current-carrying plates and dielectric spacers with apertures for current-carrying and heavy-duty fastening elements, a front plug and rear plug, and is current-carrying and heavy-duty fastening elements, wherein the surface of the current-carrying plates is provided with a porous ceramic dielectric coating. The technical result is increasing the efficiency of purifying and reclaiming dielectric fluids; increasing the useful volume of the vacuum tank without increasing the dimensions thereof; reducing the dispersivity of the fluid sprayed from the atomizer; simplifying the design; stabilizing the electromagnetic field of the electric filter; increasing the surface area of the electric filter by creating a developed surface of current-carrying filter elements without changing filter size and mass; improving reliability and ease of use; and reducing materials consumption.

A deaeration device for a fluid includes a reservoir that contains a portion of the fluid, a fluid flow path that carries a portion of the fluid, a pressure regulating structure that creates a pressure gradient along the fluid flow path, a fluid exit in the fluid flow path, and a fluid entrance in the fluid flow path. The pressure gradient causes some of the fluid to exit the fluid flow path through the fluid exit and join the fluid in the reservoir. The pressure gradient causes some of the fluid from the reservoir to join the fluid flow path through the fluid entrance.

Multiple types of UFB-containing liquids are generated for each gas contained by the UFBs, and the UFB-containing liquids are mixed with each other based on a mix proportion of a desired UFB concentration.

A three-stage tubular T-shaped degassing device with microbubble axial flow and spiral flow fields is provided, which is applied to quick degassing of a gas-liquid two-phase flow. The three-stage tubular T-shaped degassing device adopts a quick degassing technology combining a microbubble uniform mixed rotational axial flow field and a spiral runner conical spiral flow field with layered jet collision reversing depth degassing. A microbubble uniform mixer is configured to adjust gas-liquid two-phase flow containing big bubbles into microbubble uniform mixed axial flow. A microbubble cyclone is configured to adjust the microbubble uniform mixed axial flow into multiple strands of rotational axial flows containing microbubbles. A rotational axial flow degasser implements the horizontal type microbubble uniform mixed multiple strands rotational axial flow degassing operation to remove most microbubbles to form axial flow gas and axial flow liquid.

Methods and apparatuses are provided for deaeration of a liquid. Liquid may be impinged onto an inclined baffle and forced through a first plurality of apertures that direct the liquid in one or more directions away from one or more outlets of a reservoir. The liquid may be passed through a second plurality of apertures. Flowing the liquid as described promotes a circuitous route of travel and provides a residence time inside of the reservoir that promotes release of entrained air.

A fluid delivery system may include a fluid reservoir that may include a fluid supply port through which fluid is supplied to the fluid reservoir, a fluid outlet port through which a first portion of discharged fluid is supplied from the reservoir to a fluid ejection device, a fluid inlet port through which a second portion of the discharged fluid is recirculated back to the reservoir and through which air is pushed into the reservoir and an atmospheric vent to vent the air, that was pushed into the reservoir through the fluid inlet port, from the reservoir.
