Abstract
1. Способ диагностирования производительности форсунок, заключающийся в том, что устанавливают форсунки в рампе, сжимают находящийся в рампе газ, подавая в рампу тестовую жидкость, пропускают под давлением сжатого газа через форсунки тестовую жидкость, измеряют и сравнивают измеряемые параметры, отличающийся тем, что в качестве измеряемых параметров выбирают давление сжатого газа и интервалы времени, за которые происходит изменение давления сжатого газа на фиксированную величину, пропорциональную израсходованному объему жидкости для каждой из сравниваемых форсунок, при этом разброс производительности форсунок определяется как обратно пропорциональная величина разбросу величины интервала времени. ! 2. Устройство диагностирования производительности форсунок, содержащее две емкости, одна из которых рампа, комплект форсунок, жесткозакрепленных в рампе, измеритель времени, отличающееся тем, что вторая емкость выполнена в виде сливной камеры, в которую направлены распылители форсунок, в устройство диагностирования производительности форсунок дополнительно введены контроллер, включающий измеритель времени, датчик давления воздуха, первый и второй электромагнитные клапаны, сливная трубка, трубопровод и насос, причем рампа выполнена герметичной, с размещенными на ней первым и вторым электромагнитными клапанами, электронный датчик давления воздуха, размещен в верхней части рампы и соединен с контроллером, второй электромагнитный клапан через сливную трубку соединен со сливной камерой, а первый электромагнитный клапан через трубопровод и расположенный на нем насос также соединен со сливной камерой. 1. A method for diagnosing the performance of nozzles, which consists in installing nozzles in a ramp, compressing the gas in the ramp by supplying test fluid to the ramp, passing test fluid under pressure of compressed gas through nozzles, measuring and comparing the measured parameters, characterized in that as the measured parameters, the pressure of the compressed gas and the time intervals for which the pressure of the compressed gas changes by a fixed value proportional to the consumed liquid volume for each of the compared nozzles, while the variation in the performance of the nozzles is defined as the inverse proportion to the variation in the value of the time interval. ! 2. A device for diagnosing the performance of nozzles, containing two containers, one of which is a ramp, a set of nozzles rigidly fixed in the ramp, a time meter, characterized in that the second tank is made in the form of a drain chamber, into which nozzle nozzles are directed, to the device for diagnosing the performance of nozzles a controller was introduced, including a time meter, an air pressure sensor, first and second electromagnetic valves, a drain pipe, a pipeline and a pump, and the ramp was made sealed, with the first and second solenoid valves placed on it, an electronic air pressure sensor is located at the top of the ramp and connected to the controller, the second solenoid valve is connected to the drain chamber through the drain pipe, and the first solenoid valve through the pipeline and the pump located on it connected to the drain chamber.
