Description

УСТРОЙСТВО дл  ЗАМЕРА ПРОИЗВОДИТЕЛЬНОСТИ НАСОСОВ. РАБОТАЮЩИХ НА СОЗДАНИЕ ВАКУУМАDEVICE FOR MEASURING THE PERFORMANCE OF PUMPS. WORKING ON THE CREATION OF A VACUUM

За влено 12 августа 1961 г. за Х 742109/26-10 в Комитет по делам изобретений и открытий ири Совете Министров СССРIt was filed on August 12, 1961 for Х 742109 / 26-10 to the Committee for Inventions and Discoveries and the Council of Ministers of the USSR

Известны устройства, основанные на нснользованин кинетической энергии сжатого воздуха, создающего разрежение в присоединенном к устройству испытуемом объекте, и содержащие корпус, выполненный из телескопически скрепленных между собой трубок, регу,тируемый дроссель и вакуумметр.Known devices are based on the use of the kinetic energy of compressed air, which creates a vacuum in the test object attached to the device, and contains a body made of telescopically fastened tubes, a regulator, a throttle and a vacuum gauge.

Описываемое устройство предназначено дл  замера производительности насосов, работающих на создании вакуума. Это устройство имеет целью осуществл ть замер ироизводительности насосов по величине скоростного напора в сечении сопла. Достигаетс  это применением трубки скоростного напора, установленной в сопле переменного сечени  и подключенной к указателю скорости.The described device is designed to measure the performance of pumps operating in vacuum. This device aims to measure the performance of pumps by the magnitude of the velocity head in the cross section of the nozzle. This is achieved by using a velocity head tube installed in a variable cross section nozzle and connected to a speed indicator.

На фиг. 1 показано устройство в осевом разрезе; на фиг- 2 то же, вид с торца. .FIG. 1 shows the device in axial section; in fig- 2 the same, end view. .

Корпус устрой.ства состоит из трех стальных трубок /, 2 и 3, телескопически скрепленных между собой с пронайкой в щвах по окружности . В трубке 3 вмонтирован дроссель 4, а в трубке 2 - сопло 5 переменного сечени  по длине; кроме того, в этой трубке концентрично ей вмонтирована трубка 6 скоростного напора, установленна  в сопле 5 переменного сечени . В полости этой трубки имеютс  две отводные трубки 7 и 5, подключенные к указателю скорости, а к полости трубки / подключен патрубок 9 к вакуумметру. Устройство при замере производительности устанавливаетс  на всасывающий патрубок испытуе.мого насоса.The case of the device consists of three steel tubes I, 2 and 3, telescopically fastened together with a piercing in the grooves around the circumference. The choke 4 is mounted in the tube 3, and the nozzle 5 of variable cross-section along the length in the tube 2; In addition, in this tube there is a concentric tube of velocity head 6 mounted in the nozzle 5 of variable cross section concentric with it. In the cavity of this tube, there are two outlet tubes 7 and 5 connected to the speed indicator, and a branch pipe 9 to the vacuum gauge is connected to the cavity of the tube /. The device, when measuring performance, is installed on the suction inlet of the test pump of my pump.

При работе насоса поток воздуха обтекает дроссель - и в узком сечении сопла 5 увеличивает свою поступательную скорость. Создаваемое при этом статическое и динамическое давление воспринимаетс  трубкой 6 скоростного напора и по двум отводным трубкам 7 и 5 передаютс  в указатель скорости.When the pump is operating, the air flow around the throttle increases its forward velocity in a narrow section of the nozzle 5. The static and dynamic pressure created in this case is perceived by the velocity head tube 6 and transmitted through the two outlet tubes 7 and 5 to the speed indicator.

Торможением потока воздуха дросселем 4 в корлусе насоса и в данном устройстве устанавливаетс  заданный вакуум, который замер етс  вакуумметром, а изменение скоростного напора - положением стрелки на шкале указател  скорости.By decelerating the air flow, the throttle 4 in the pump corulus and in this device establishes a predetermined vacuum, which is measured with a vacuum gauge, and the change in velocity head - by positioning the arrow on the scale of the speed indicator.

Включаемые в устройство термометр и барометр используютс  дл  определени  значени  поправок от изменени  температуры и давлени  в атмосфере.Thermometers and a barometer included in the device are used to determine the value of corrections for changes in temperature and pressure in the atmosphere.
