Description

Стенд предназначен дл исследовани аппаратуры , нодающей жидкость в среду с переменным давлением газа, например в цилиндры двигателей внутреннего сгорани .The test bench is designed for studying equipment that injects liquid into a medium with variable gas pressure, for example, into cylinders of internal combustion engines.
Известны стенды, содержащие снабженную индикатором камеру, соединенную с источником давлени газа с помощью дозирующего устройства.Stands are known that contain an indicator-supplied chamber connected to a source of gas pressure using a metering device.
Недостаток известных конструкций заключаетс в невозможности регулировани противодавлени в камере в соответствии с реальными услови ми в цилиндре.A disadvantage of the known constructions is the impossibility of adjusting the back pressure in the chamber in accordance with the actual conditions in the cylinder.
С целью регулировани противодавлени в камере дозирующее устройство соедин етс с двигателем, например, электрическим.In order to regulate the back pressure in the chamber, the metering device is connected to an engine, for example, an electric one.
На чертеже приведена схема предлагаемого стенда.The drawing shows the scheme of the proposed stand.
Стенд содержит камеру 1 с индикатором 2, выполненным, например, в виде прозрачных стенок камеры, дозирующее устройство 3, соединненое с камерой 1 и электродвигателем 4, аккумул тор газа 5, соединенный через редуктор 6 с источником давлени газа 7. В камере 1 установлены элементы 8, например форсунки испытываемой впрыскивающей аппаратуры .The stand contains a chamber 1 with an indicator 2 made, for example, in the form of transparent walls of the chamber, a metering device 3 connected to the chamber 1 and an electric motor 4, a gas accumulator 5 connected via a gearbox 6 to a gas pressure source 7. The chamber 1 has elements 8, for example the nozzles of the injection equipment under test.
Но трубопроводам газ поступает от источника давлени 7 через редуктор 6, аккумул тор 5 ц дозирующее устройство 3 в камеру 1.But the pipeline receives gas from the pressure source 7 through the gearbox 6, the battery 5 c dosing device 3 into the chamber 1.
Вращение электродвигател 4 приводит к соединению каналов дозирующего устройства 3 с камерой 1 или атмосферой, измен противодавление в камере. Увеличением или уменьшением числа оборотов электродвигател 4 регЗлируетс характер противодавлени в камере 1 вследствие изменени во времени сечени каналов дозирующего устройства 3.The rotation of the electric motor 4 leads to the connection of the channels of the metering device 3 with the chamber 1 or the atmosphere, changing the back pressure in the chamber. An increase or decrease in the number of revolutions of the electric motor 4 regulates the nature of the counterpressure in chamber 1 due to the time variation of the cross section of the channels of the metering device 3.
Нредмет изобретени Nredmet of the invention
1.Стенд дл испытани впрыскивающей аппаратуры , содержащий снабженную индикатором камеру, соединенную с источником давлеии газа с иомощью дозирующего устройства, отличающийс тем, что, с целью регулировани противодавлени в камере, дозирующее устройство соединено с двигателем, например электрическим.1. A test bench for testing injection equipment comprising an indicator-supplied chamber connected to a gas pressure source with a pressure metering device, characterized in that, in order to regulate the backpressure in the chamber, the dosing device is connected to an engine, for example, an electric one.
2.Стенд по и. 1. о т „т и ч а ю щ и и с тем, что между дозирующим устройством и источником давлени размещен аккумул тор газа с редуктором.2. Stand on and. 1. About the fact that the gas accumulator with a reducer is placed between the metering device and the pressure source.
