Description

,1,one

Известен струйный насос с переменной площадью поперечного сечени  выходного сопла.A jet pump is known with a variable cross-sectional area of the outlet nozzle.

Предложенный насос отличаетс  от известного тем, что стенки его камеры смешени  и выходного сопла выполнены эластичными и охвачены глухой камерой, сообщенной с выходом насоса. Благодар  этому режим течени  жидкости в насосе мен етс  автоматически в зависимости от нагрузки на выходе насоса.The proposed pump differs from the well-known in that the walls of its mixing chamber and the outlet nozzle are elastic and are covered by a blind chamber communicated with the outlet of the pump. Due to this, the mode of fluid flow in the pump changes automatically depending on the load on the pump outlet.

Конструктивна  схема насоса показана на чертеже..,.The design scheme of the pump is shown in the drawing ..,.

Струйный насос состоит из корпуса 1, сопла 2, камеры смещени  3, диффузора 4, подвод щего патрубка 5 и трубки 6, сообщающей глухую камеру 7 с полостью напорного трубопровода .The jet pump consists of a housing 1, a nozzle 2, a displacement chamber 3, a diffuser 4, a supply nozzle 5 and a tube 6, which connects the deaf chamber 7 with the cavity of the discharge pipe.

При уменьщении потреблени  воды давление в напорном трубопроводе повыщаетс  и через трубку 6 передаетс  в камеру 7, что приводит к сужению проходного сечени  камеры смещени . В этом случае при сохраНении площади солла будет происходить снижение подачи струйного насоса.When water consumption decreases, the pressure in the pressure pipe rises and passes through tube 6 to chamber 7, which narrows the flow area of the displacement chamber. In this case, while maintaining the salt area, there will be a reduction in the jet pump supply.

При обратном  влении, т. е. при снижении давлени  в напорном трубопроводе, что вызвано большим потреблением воды, рабочее сечение камеры смещени  3 увеличиваетс , вследствие чего возрастает подача струйного насоса.With a reverse effect, i.e., with a decrease in pressure in the pressure pipe, which is caused by a large water consumption, the working section of the displacement chamber 3 increases, as a result of which the jet pump feed increases.

Предмет изобретени Subject invention

Струйный .насос с переменной площадью поперечного сечени  приемного сопла, выполненного задело с камерой смещени , отличающийс  тем, что, с целью автоматического изменени  режима течени  жидкости в насосе, стенки камеры смешени  выполнены эластичными и охвачены глухой камерой, сообщенной с выходом насоса.The jet pump with a variable cross-sectional area of the receiving nozzle made from the displacement chamber, characterized in that, in order to automatically change the flow of fluid in the pump, the walls of the mixing chamber are elastic and covered by a deaf chamber connected to the pump outlet.
