Abstract
Устройство для измерения статического давления в потоке жидкости или газа, содержащее шаровидный пористый насадок и диаметрально размещенную в нем одним концом приемную трубку, отличающееся тем, что, с целью уменьшения погрешности измерения в нем, внутри пористого насадка выполнена сферическая камера, размещенная по его диаметральной оси со смещением от центра насадка на величину, удовлетворяющую соотношениюξ=(0,20-0,25)d,при этом конец приемной трубки размещен в полости сферической камеры со стороны большего ее расстояния от поверхности пористого насадка, а величины диаметров пористого насадка d, сферической камеры dи внутреннего диаметра приемной трубки dсвязаны между собой следующими соотношениямиd=(0,19-0,22)d;d=(0,05-0,10)d,где ν - кинематическая вязкость жидкости (газа), м/с;K- коэффициент проницаемости материала насадка, м;m - коэффициент пористости материала насадка;V- максимально возможная скорость потока жидкости (газа), м/с.A device for measuring static pressure in a stream of liquid or gas containing a spherical porous nozzle and a receiving tube diametrically placed in it at one end, characterized in that, in order to reduce measurement error, a spherical chamber is placed inside the porous nozzle placed along its diametral axis offset from the center of the nozzle by an amount satisfying the ratio ξ = (0.20-0.25) d, while the end of the receiving tube is placed in the cavity of the spherical chamber from the side of its greater distance from the surface n the nozzle nozzle, and the diameters of the porous nozzle d, the spherical chamber d, and the inner diameter of the receiving tube d are connected to each other by the following relations d = (0.19-0.22) d; d = (0.05-0.10) d, where ν - kinematic viscosity of a liquid (gas), m / s; K - material permeability coefficient of the nozzle, m; m - material porosity coefficient of the nozzle; V - maximum possible flow rate of the liquid (gas), m / s.
