A pump for exhausting air [or steam] or other as from an enclosed space to a desired degree of vacuum.  4, record 1, English, - vacuum%20pump

Record number: 1, Textual support number: 1 CONT

These same basic components may be used in the design of a vacuum or a subatmospheric system. The vacuum heating pump maintains a vacuum in the return piping under all operating conditions, assisting the supply steam in overcoming the resistance of the system piping and assuring rapid and uniform steam distribution.  2, record 1, English, - vacuum%20pump

Record number: 1, Textual support number: 2 CONT

Vacuum pumps are used on a system where the returns are under a vacuum. The assembly consists of a receiver, separating tank and automatic controls for discharging the condensate to the boiler. Vacuum pumps are sized in the same manner as condensate pumps for a delivery of 2. 5 to 3 times the design condensing rate.  2, record 1, English, - vacuum%20pump

Chauffage à pression sous-atmosphérique. [...] Les pompes à vide sont de deux sortes : 1. les pompes à piston, activées par la vapeur, aspirantes et foulantes, et, 2. les pompes centrifuges accouplées directement à un moteur électrique.  2, record 1, French, - pompe%20%C3%A0%20vide

Chauffage à vapeur sous vide. Une pompe à vide permet d'obtenir dans l'installation une pression inférieure à la pression atmosphérique [...] Le vide est parfois réalisé à l'aide d'une pompe refoulant l'eau condensée dans la chaudière et munie d'un système d'injecteurs appropriés [...]  3, record 1, French, - pompe%20%C3%A0%20vide

Pour les grands édifices [...] il est difficile de placer tous les échangeurs de chaleur au-dessus du niveau d'eau du générateur ou de la tuyauterie de retour. On utilise dans ce cas une pompe à vide qui maintient une pression inférieure à la pression atmosphérique (jusqu'à 650 mm de Hg) dans la tuyauterie générale de retour [...]  4, record 1, French, - pompe%20%C3%A0%20vide

The condensate that forms in the dryer cylinders is removed by a specially-designed syphon assembly.... at the high speeds of modern paper machines, the condensate layer has become so immobilized that even a very thin layer is a significant impediment to heat flow. Fortunately, the condensate layer still has some peripheral motion at high machine speed. This motion can be converted into a wave action by means of "dryer bars" attached axially to the interior surface of the dryer cylinder. This wave action(called "sloshing") greatly decreases the thermal resistance of the rimming condensate, and thus allows an increased rate of heat transfer.  1, record 3, English, - sloshing

The rate of change of temperature with height in a rising air parcel when, under the most simplified conditions, the condensate(assumed to be water) immediately precipitates out.  1, record 4, English, - pseudo%2Dadiabatic%20lapse%20rate

Record number: 4, Textual support number: 1 OBS

The pseudoadiabatic lapse rate is so close to the moist adiabatic lapse rate that meteorologists tend to ignore this difference and often refer to them synonymously. In fact, on adiabatic charts (or pseudoadiabatic charts), the moist adiabatic lapse rate lines are referred to interchangeably as moist, saturated, or pseudoadiabatic.  4, record 4, English, - pseudo%2Dadiabatic%20lapse%20rate

A district steam-heating complex is composed of one or more steam generating plants, a network of mains, and meters on the premises of each customer.... The rate of flow of steam is accomplished through a steam-flow meter or a condensate meter. A steam-flow meter measures the pressure difference from the high-pressure input connection to the low-pressure outlet. This difference is translated into a measure of energy.  1, record 5, English, - steam%2Dflow%20meter

A district steam-heating complex is composed of one or more steam generating plants, a network of mains, and meters on the premises of each customer.... The rate of flow of steam is accomplished through a steam-flow meter or a condensate meter.... A condensate meter is less expensive than a steam-flow meter, but its use depends on the ability to collect the condensate for measurement.  1, record 6, English, - condensate%20meter
