Abstract
1. Опорное устройство для датчиков давления, выполненных с возможностью установки внутри камер (7) сжатия центробежных вентиляторов (1), содержащее корпус (11) с в основном продольным прохождением с проходящей внутри вдоль указанного направления продольного прохождения проходной трубой (12) и открытой на продольных концах (12а, 12b), при этом указанный корпус содержит первую часть (13) для обеспечения опоры на корпус вентилятора и вторую часть (15), проходящую от указанной первой части (13), выполненную с возможностью погружения в поток, создаваемый камерой (7) сжатия вентилятора, посредством заданного позиционирования соответствующего концевого отверстия трубы внутри указанного потока, с целью измерения с помощью трубы (12) сигнала давления, отличающееся тем, что вторая часть (15) указанного корпуса (11) имеет поперечное сечение поперек указанного направления продольного прохождения, имеющее форму аэродинамического профиля с низким коэффициентом сопротивления.2. Устройство по п.1, в котором указанный аэродинамический профиль является постоянным вдоль указанного направления продольного прохождения указанной второй части (15).3. Устройство по любому из п.1 или 2, в котором указанный аэродинамический профиль является симметричным.4. Устройство по п.1, в котором указанный аэродинамический профиль выбран из стандартных аэродинамических профилей.5. Устройство по п.4, в котором указанный аэродинамический профиль является профилем NACA.6. Устройство по п.1, в котором плоскость, содержащая аэродинамический профиль, свободного конца указанной второй части (15) наклонена относительно плоскости, перпендикулярной направлению продольного п1. A support device for pressure sensors configured to be installed inside the compression chambers (7) of centrifugal fans (1), containing a housing (11) with a mainly longitudinal passage with a passage pipe (12) running inside along the specified direction of the longitudinal passage and open to longitudinal ends (12a, 12b), wherein said housing comprises a first part (13) for providing support on the fan housing and a second part (15) extending from said first part (13), configured to be immersed in the flow created by the chamber ( 7) compressing the fan, through a given positioning of the corresponding end hole of the pipe within the specified flow, for the purpose of measuring with the help of the pipe (12) a pressure signal, characterized in that the second part (15) of the specified housing (11) has a cross section across the specified direction of the longitudinal passage , having the shape of an aerodynamic profile with a low drag coefficient.2. Device according to claim 1, wherein said airfoil is constant along said longitudinal direction of said second part (15).3. Device according to any one of claims 1 or 2, wherein said airfoil is symmetrical.4. The device according to claim 1, wherein said airfoil is selected from standard airfoils.5. The device according to claim 4, wherein said airfoil is a NACA airfoil.6. Device according to claim 1, in which the plane containing the airfoil of the free end of said second part (15) is inclined relative to a plane perpendicular to the direction of the longitudinal
