Изобретение относитс к турбо- и компрессоростроению и может быть использовано во входных устройствах турбин и компрессоров с радиально-ос вым входом рабочего тела,The invention relates to a turbo and compressor engineering and can be used in the input devices of turbines and compressors with a radial-base input of the working fluid,
Цель изобретени - снижение гидравлических потерь.The purpose of the invention is to reduce hydraulic losses.
На фиг. I показано входное устрой ствоJ меридиональное сечение; на фиг. 2 разрез А-А на фиг. Ij на фиг. 3 - сечение Б-Б на фиг. 1.FIG. I shows the input device; a meridional section; in fig. 2, section A-A in FIG. Ij in FIG. 3 is a section BB in FIG. one.
Входное устройство турбоманшны содержит установленные последовательно по ходу потока всасывающий патрубок 1 , полуспиральную камеру 2 и радиаль но-осевой осесимметричньй конфузор 3 с криволинейными спр мл ющими лопат нами 4. Входной участок 5 каждой лопатки 4 расположен в радиальной част 6 конфузора 3 и имеет в поперечном сечении форму дуги с радиусом д определ емым из уравнени аОкThe input device of a turbomanshna contains a suction pipe 1, a semi-spiral chamber 2 and a radial-axial axisymmetric confuser 3 with curvilinear spraying blades 4 installed in series along the flow. The inlet section 5 of each blade 4 is located in the radial part 6 of the confuser 3 and has section of the shape of an arc with a radius g determined from the equation aOK

Во всасывающем патрубке 1 могут быть выполнены выточки 7,Undercuts 7 can be made in the suction inlet 1,
Входное устройство работает следующим образом,The input device works as follows
Рабочее тело поступает во всасьг- вающий патрубок 1, далее раздел етс на два потока и через полуспиральную камеру 2 направл етс на криволинейные спр мл ющие лопатки 4, Расположение входных участков 5 лопаток 4, а также выполнение их в виде формы дуги с радиусом R по предлагаемому уравнению обеспечивает равномерное поле скоростей при выходе из устрой- -ства, а также снижение гидравличес- кюс потерь, The working fluid enters the aspiration nipple 1, then is divided into two streams and directed through the semi-spiral chamber 2 to the curvilinear alignment vanes 4, the arrangement of the inlet sections 5 of the vanes 4, and also their execution in the form of an arc with a radius R along the proposed equation provides a uniform velocity field at the exit from the device, as well as a decrease in hydraulic losses,
