Description

н ютс  к манометрам, на каждой точке характеристики турбомашииы (ири иосто нных значени х частоты вращени  рабочего колеса и расхода газа) измер ютс  восиринимаемые трубками приемника нолные давлени .At each point, the characteristics of the turbomachine (or the constant values of the impeller rotation frequency and gas flow rate) are measured by the total pressure generated by the receiver tubes.

Достоинством ириемника  вл етс  то, что он позвол ет осуществить проток газа и этим самым заметно увеличить нечувствительность к углу скоса потока (с air ±10°, до ), при щаге 5(2,0- 2,5) d и обесиечить ногрещность измерени  иолного давлени  в диапазоне углов , не превышающую 0,5%.The advantage of the receiver is that it allows to carry out the gas flow and thereby significantly increase the insensitivity to the slope angle of the flow (with air ± 10 °, up to), with schag 5 (2.0-2.5) d and relieve and an absolute pressure in the range of angles not exceeding 0.5%.
