Abstract: FIELD: drying solid semiproducts; short-cut macaroni, for example, tea, berries, medicinal herbs, vegetables and fruits. SUBSTANCE: plant has framework 1 made from vertical and horizontal uprights 3 and 4 inclined relative to spreader 15 smoothly distributing products over entire width of belt. Belts of upper conveyer are mounted in parallel relative to one another. Framework is assembled from individual sections. Last section from spreader is provided with drive mechanism; infra-red radiation heating elements mounted above upper working run of belt in each section are rigidly connected with framework and are provided with reflectors which give support for lower runs 12 of belt. Adjacent conveyers are made for rotation of belts in opposite directions; odd conveyers are shifted lengthwise towards spreader by amount sufficient for transfer from conveyer to conveyer. Heating elements are switched on individually by means of toggle switches. Shielding panels 17 mounted above ends of belt have form of ladles made from synthetic material; they are rigidly connected with framework and exclude pouring of material in transfer. Continuous belts are made from synthetic material. Loading bin 16 is located in first section (from spreader) above working run of belt and unloading chute is mounted under lower conveyer in last section. Drive mechanism consists of DC electric motor, spiroidal reduction gear, chain transmission, V-belt transmission and drive drums. Driven drums, tensioner 25 and electric cabinet are located in first section (from spreader). Driven and drive drums are connected in pairs by means of belts. Guide angles available in framework give support for working runs of each belt. Detachable attached casings are mounted on framework above upper conveyer. Drying the product is effected by progressive method of intermittent radiation when heating of the product by infra-red rays is combined with cooling said product by air, thus excluding cracking and warpage. Modular construction of framework makes easy maintenance of drive mechanism with no limitation pertaining to length of motion, volume of product and partial load of mechanism. Noiseless heating elements reduce level of noise. EFFECT: enhanced efficiency and reliability. 2 cl, 3 dwg

Abstract: Изобретение относится к области насосной техники, преимущественно к скважинным насосным установкам для добычи нефти. Способ работы скважинной насосной установки при освоении скважины включает спуск на каротажном кабеле струйного насоса в скважину во внутреннюю полость колонны насосно-компрессорных труб (НКТ) вместе с расположенным ниже насоса геофизическим прибором. Насос устанавливают в опоре, размещенной на НКТ и имеющей перепускные окна для осуществления откачки среды из подпакерной зоны скважины. Ниже опоры производят размещение разъединительно-соединительного устройства колонны НКТ, обратного клапана пакера и перфоратора. Спуск и размещение в опоре насоса проводят после распакеровки пакера. Геофизический прибор устанавливают над обратным клапаном, и путем подачи эжектирующей среды в сопло насоса создают необходимую величину депрессии на пласт, которая фиксируется с помощью геофизического прибора на поверхности. Производят подрыв перфоратора с одновременной откачкой через фильтр и обратный клапан пластового флюида. После достижения стабильного притока добываемого флюида прекращают подачу эжектирующей среды в сопло насоса, извлекают с помощью каротажного кабеля прибор и насос из скважины. При этом обратный клапан закрывается, предотвращая попадание в подпакерную зону жидкости из пространства над обратным клапаном и загрязнение ею прискважинной зоны. Сбрасывают во внутреннюю полость колонны НКТ блокирующую вставку со сквозным продольным каналом, которая перекрывает перепускные окна опоры, разобщая при этом межтрубное пространство и внутреннюю полость колонны НКТ. Подачей через циркуляционный клапан облегченной жидкости или инертного газа из межтрубного пространства во внутреннюю полость колонны НКТ снижают гидростатическое давление над обратным клапаном и таким образом запускают скважину в работу фонтанным способом. После истощения энергии пласта извлекают блокирующую вставку, спускают в скважину струйный насос вместе с геофизическим или автономным прибором, проводят откачку пластового флюида при заданных разной величины уровнях депрессии на пласт. При этом фиксируют дебит скважины, строят график зависимости дебита скважины от величины депрессии и по этому графику определяют типоразмер насоса для принудительной эксплуатации скважины. Извлекают насос с прибором на поверхность, посредством соединительно-разъединительного устройства отсоединяют верхнюю часть колонны НКТ вместе с опорой и извлекают ее на поверхность. При этом обратный клапан предотвращает попадание жидкости из скважины выше обратного клапана в подпакерную зону. Затем в скважину спускают на колонне НКТ насос для принудительной добычи нефти, подсоединяют его к нижней части колонны насосно-компрессорных труб и запускают скважину в работу принудительным способом. Изобретения направлены на оптимизацию размеров элементов конструкции, повышение надежности работы скважинной струйной установки. 2 с.п.ф-лы, 5 ил.

Abstract: FIELD: textile production. SUBSTANCE: the method consists in fusion of polymer to the operating temperature, formation of a melt film of an equal thickness around the edges of the rotary reactor installed vertically in a protective chamber and made in the form of a cylinder with an expanding taper part at the reactor outlet. A spinneret with equal flow ducts is installed inside the reactor before the taper part. Formation of the melt film into a fiber is accomplished by separation of the film by the flow equal ducts of the spinneret into separate equal stream-lines, which then acquire kinetic energy due to rotation of taper part of the reactor, and stretch into a fiber with the taper part of the reactor at a simultaneous influence of the formed air flow. A mass of fibers is formed from the obtained fibers into a fibrous canvas on the receiving conveyer. The installation of production of fibrous canvas from a termosoftening plastic material includes an extruder, branch pipe for feeding the melt from the extruder, protective chamber with a rotary reactor vertically installed in it and a motor of its drive, annular hollow duct, receiving conveyer and a rectangular slotted air duct installed under it, filter for cleaning of waste air, exhaust and forced-draught fans. The spinneret is positioned inside the reactor on the same shaft, the outer part of the spinneret is protected by a heat-insulating screen. The installation has a feeding conveyer actuated by a drive with a receiving conveyer. The latter is installed for adjustment in height. The protective chamber is made with double walls filled with heat-insulating material.

When time period of change of electric current of load and changing rate of electric current of load correspond to predetermined designed values, it is judged that self-oscillation mode exists in electromechanical system " electric motor - pinch roll - ingot" or there is slipping of pinch roll on ingot or periodically there is no contact between pinch roll and ingot. Bending value (mm) of pinch roll is evaluated according to first harmonic component of spectrum of changes of electric current values of load of electric motors of pinch rolls. Wear degree of drive units of pinch rolls is evaluated on base of changes of electric current of load of electric motors of pinch rolls measured for good working equipment before beginning of casting process.
