Description
Изобретение относитс к компрес- соростроению и может быть использовано в диффузорах центробежных компрессоров.The invention relates to compressor building and can be used in diffusers of centrifugal compressors.
Цель изобретени - повьшение КПД компрессора.The purpose of the invention is to increase the efficiency of the compressor.
На фиг.1 показан диффуэор, меридиональный разрез; на фиг.2 - вид А на фиг.1. Figure 1 shows the diffuor, meridional section; figure 2 - view And figure 1.
Диффузор центробежного компрессора содержит боковые стенки 1 и 2 и закрепленные на них укороченные лопатки 3 и 4. Лопатки 3 закреплены на одной из стенок 1, а лопатки 4 - на другой стенке 2 и имеют различные углы , и tfj установки.The centrifugal compressor diffuser contains side walls 1 and 2 and shortened blades 3 and 4 fixed to them. Blades 3 are fixed on one of the walls 1, and blades 4 on the other wall 2 and have different angles, and tfj installations.
Диффузор работает следующим образом.The diffuser works as follows.
Рабочее тело поступает в диффузор из рабочего колеса. При течении рабочего тела в диффузоре между его стенками 1 и 2 происходит торможение и повьппение статического давлени . Различные углы установки лопаток 3 и 4 обеспечивают их безотрывное обтекание, что .повышает КПД компрессора.The working fluid enters the diffuser from the impeller. When the working fluid flows in the diffuser between its walls 1 and 2, the static pressure decelerates and is twisted. Different angles of installation of the blades 3 and 4 ensure their continuous flow, which increases the efficiency of the compressor.
