本文对18GJ增压器通过平台试验分别用三种型号叶片扩压器、作了压气机特性曲线,并对试验结果作了分析。通过运行证明结构强度和轴承均工作可靠。该增压器可供匹配流量0.57—1.1公斤/秒,增压压力1.83—2.5公斤/米厘~2范围内柴油机的增压之用。
In this paper, 18GJ turbochargers were tested by platform test with three models of leaf diffuser, the compressor characteristics curve, and the test results were analyzed. Through the operation proved that the structural strength and bearing are reliable. The turbocharger can be used to match the flow of 0.57-1.1 kg / sec, supercharged pressure of 1.83-2.5 kg / mili ~ 2 diesel engine supercharged purposes.
