Изобретение относитс к насосо- строению, а именно к способу пуска дальнейструйной дождевальной установки .The invention relates to a pump construction, namely to a method for starting a further sprinkler installation.
Известен способ пуска дальнеструйной дождевальной установки путем заполнени центробежного насоса водой и запуска приводного двигател flA known method of starting a long-range sprinkler installation by filling the centrifugal pump with water and starting the drive motor fl
Однако известный способ не может быть реализован при пологой мощностной характеристике на режиме запуска, имеющей место у газотурбинных двигателей , применение которых в дождевальных установк ах вызвано необходимостью повышени эффективности «рождевани . При псйлтке одновременного пуска газотурбинного двигател и насоса , предварительно заполненного водой в нерабочем состо нии, установка не запускаетс , так как мс цность двигател на режиме пуска недостаточна дл привода насоса.However, the known method cannot be implemented with a flat power characteristic in the launch mode, which occurs in gas turbine engines, the use of which in sprinklers is caused by the need to increase the efficiency of "birth." With the simultaneous start-up of a gas turbine engine and a pump that is pre-filled with water in an inoperative state, the installation does not start, because the engine speed in the start-up mode is insufficient to drive the pump.
Цель изобретени - обеспечение надежного пуска установки с приводным газотурбинным двигателем.The purpose of the invention is to ensure a reliable start-up of the installation with a gas turbine driving engine.
Поставленна цель достигаетс тем, что вначале запускают двигатель а заполнение насоса водой осуществл ют после выхода двигател на заданНЫй режим работы.The goal is achieved by first starting the engine and filling the pump with water after the engine has entered the set operating mode.
На фиг. 1 представлена дальнеструйна дождевальна установка дл реализации способа, общий вид; на фиг. 2 - элементы конструкции насоса установки.FIG. Figure 1 shows a long-range sprinkler installation for the implementation of the method, a general view; in fig. 2 - design elements of the pump installation.
Дальнеструйна дождевальна установка содержит центробежный насос 1 и приводной двигатель 2, которые размещены на ходовой части 3. Рабо0 чее колесо 4 насоса 1 жестко соединено с валом (не показан) двигател 2. Насос 1 имеет всасывающий трубопровод 5, заборна часть 6 которого погружена в канал 7, и напорный трубопровод 8. У втулки .9 рабочего колеса 4 со стороны входа в насос 1 размещено заборное отверстие трубки 1.0, сообщенной с отсасывающим устройством , например эжектором Сне по0 казан) .The longitudinal sprinkler installation contains a centrifugal pump 1 and a driving motor 2, which are located on the undercarriage 3. The working wheel 4 of the pump 1 is rigidly connected to the shaft (not shown) of the engine 2. The pump 1 has a suction pipe 5, the intake part 6 of which is immersed in the channel 7, and the pressure pipe 8. At the sleeve .9 of the impeller 4, from the side of the entrance to the pump 1 there is an intake port of tube 1.0, which is in communication with a suction device, for example, the ejector Sleep (shown).
Способ осуществл етс следующим образом.The method is carried out as follows.
Запускают двигатель 2. Вместе с валом двигател 2 начинает вращать5 с рабочее колесо 4 насоса 1. После выхода двигател 2 на заданный режим работы включают в работу отоасывгиощее устройство, которое через заборное отверстие трубки 10 гфоизводит Start the engine 2. Together with the motor shaft 2 starts to rotate5 with the impeller 4 of the pump 1. After the engine 2 to the specified mode of operation, turn on the work of the outgoing device, which through the intake hole of the tube 10 produces
0 отсос воздуха, после чего происходит0 air suction, after which occurs
