Patent RU-2077861-C1 (RU)
Title: Насадок для пылесоса
Inventor: GERASIMOV ALEKSANDR N
IPC: A47L9/08
Filed: 1995-05-29
Granted: 1997-04-27
Abstract: Может быть использован с пылесосами большой производительности, предназначенными, например, для уборки гостиниц и других помещений большой площади. Состоит из корпуса со щеткой и соединенным с отсасывающей полостью корпуса патрубком, при этом щетка выполнена в виде двойного замкнутого ряда, пространство между рядами щетки связано с отсасывающей полостью, а пространство, ограниченное внутренним рядом щетки, отделено от всасывающего пространства с образованием дополнительной полости насадка, которая связана с атмосферой. Благодаря этому сохраняется большая площадь обрабатываемой поверхности, на которую воздействует щетка, и, в то же время, резко уменьшается площадь той части насадка, под которой создается высокое разряжение, так как это разряжение сохраняется только в области между рядами щетки, а в пространстве, ограниченном внутренним рядом щетки, устанавливается давление, близкое к атмосферному. Эффект может быть усилен, если внутренний ряд щетки выполнить более плотным, чем внешний. 1 з.п.ф-лы, 2 ил.

Filed: 1998-08-27
Granted: 2000-05-10
Abstract: FIELD: oil and gas production industry. SUBSTANCE: method and device can be used for intensifying evacuation of fluid from well bottom-hole. Accumulation of fluid is caused due to insufficient bed energy or changed thermodynamic characteristics of bed. According to method, bed gas is released from annular space. Speed of rising flow of gas-liquid mixture in lifting pipes is increased up to speed ensuring evacuation of liquid. This speed is determined from formula and it is created by inflow of bed gas from annular space into lifting pipes when pressure of bed gas in annular space reaches pressure of bed gas in annular space at depth of its release into lifting pipes which is determined by corresponding expression. Flow rate of bed gas released into lifting pipes, period of its release from annular space, distance from lower end of lifting pipes on which gas release unit is installed, diameter of flow bore in gas release unit - all these characteristics are determined by corresponding formulas. Application of aforesaid method and device increases output capacity of well due to effective withdrawal of liquid from bottom-hole by gas and also due to optimal positioning of gas release unit over length of lifting pipes. Evacuation of gas-fluid mixture in lifting pipes is carried out with taking consideration of actual bottom-hole conditions in optimal operation duty. EFFECT: higher efficiency. 5 cl, 7 dwg, 1 tbl
