Patent GB1054749A

1,054,749. Vacuum pumps, centrifugal pumps. NASH ENGINEERING CO. March 11, 1964 [March 18, 1963], No. 10329/64. Headings F1C and F1E. In a high vacuum system in which a primary vacuum pump 10, Fig. 4 creates the initial vacuum and an ejector 38 creates the final vacuum, a control valve 124 renders the ejector 38 inoperative during the initial vacuum stage and renders it instantly fully operative during the final vacuum stage. The primary pump 10 e. g. a liquid ring pump initially evacuates a chamber attached to flange 34. The flow is divided, one portion passing through conduit 120 and check valve 112 and the other portion passing through a supersonic diffuser 18. The pressure in manifold 114 is communicated to the upper side of piston 128, Fig. 3 (not shown) in valve 124. At a predetermined vacuum piston 128 is drawn to the top of its stroke, the movement being rapid because the pressure of ambient air from conduit 156 acts over the entire area of piston 128 when it leaves seat 142. The ejector begins functioning whilst simultaneously chamber 130 is cut off from conduit 96 and a port 160 is opened allowing atmospheric air to pass via channel 136, groove 140, and pipe 122 to the lower side of diaphragm 162 which closes valve 112. In another embodiment valve 112 is replaced by a gravity operated check valve 25, Fig. 1 (not shown), and the control valve 62, Fig. 2 (not shown), admits ambient air through an enlargement 108 of the valve housing adjacent the valve seat 82.

Abatement system

Liquid ring pumps are used to pump a variety of fluid types. The present invention provides a two stage liquid ring pump through which an exhaust gas comprising compounds to be destroyed is passed. The exhaust gas passes through the first stage to a gas abatement device, following which it is passed back to the second stage of the liquid ring pump for removal of the compounds formed in said abatement device. The stages of the liquid ring pump may be adjustable.

Degassing system, a degassing tower, and a water system having the same

The present disclosure provides a pump-assisted degassing system, a vacuum degassing tower, and a water system having the same. The degassing system comprises a vacuum pump, connected with a degassing tower through a main pipeline, and configured to pump out a gas-liquid mixture from the degassing tower; a gas-liquid separator, connected with the vacuum pump in a closed loop through a circulation pipeline, and configured to perform gas-liquid separation on the gas-liquid mixture; and a booster pump, arranged on the main pipeline between the vacuum pump and the degassing tower, and configured to assist the vacuum pump to pump out the gas-liquid mixture. The vacuum pump and the booster pump constitute a two-stage pumping device. Only one vacuum pump is needed in the system, and the vacuum pump requires less circulating water and less motor power resulting in lower the equipment load loss in the operation efficiency.

Fuel system with liquid ring pump with centrifugal air/fuel separator

A fuel system incorporating a boost pump unit, a boost pump unit and method of pumping fuel are provided. The fuel system and boost pump unit are preferably self-priming and do not utilize an airframe mounted pump for supplying fuel for an aircraft combustor. The boost pump unit includes a liquid ring pump and an air/fuel separator. The air/fuel separator has an inlet and first and second outlet ports. The inlet is operably fluidly coupled to an outlet of the liquid ring pump. The air/fuel separator has an arcuate flow path. The first outlet port is in fluid communication with a radially outer portion of the arcuate flow path and the second outlet port is in fluid communication with a radially inner portion of the arcuate flow path. A return line connected to the first outlet port is configured to return fuel to the liquid ring pump.
