J70型增压器涡轮性能试验及其分析

Tests and Analyses of Turbine Performance for Type J70 Turbocharger

本文用新近研制的一种高速小型径流涡轮测功装置,测取了J70型增压器涡轮的级性能。简述了该测功装置的特点及试验方法。给出了试验结果并就此作了分析。此种性能试验及其分析为其设计计算和增压配机提供了实际依据。

Measurement of turbine stage performance of type J70 turbocharger has been carried out in this paper with a newly developed dynamometer designed for high speed small-size radial turbines. The design feature and test method of the dynamometer have been outlined, and the test results plotted and analysed. These performance tests togather with analyses have provided a real basis for design calculations of the turbocharger and for its matching with engines.
