在哈尔科夫实验室中有一个专门试验台,在这个试验台上可进行实验用压气机的研究。Д70柴油机涡轮增压器的组成部分——离心式压气机的工作级就在该试验台上进行了研究。该试验台压气机的工作条件与在内燃机车上的情况极为相近。另一特点为压气机通流部分各元件的尺寸与Д70的原有尺寸完全一致。试验台山下列部分组成:
In Kharkiv laboratory there is a special test bed, in this test bench for experimental use of the compressor research. The components of the Д70 diesel turbocharger - the working stage of the centrifugal compressor was studied on this test rig. The working conditions of the test bench compressor and diesel locomotives are very similar. Another feature of the compressor flow through the various components of the size and the original dimensions of the same Д70. Test Taishan the following components:
