Abstract
Electric linear compressor has the merits of compact structure, easy
control, high efficiency, strong adaptability etc,.And it provide
opportunities and conditions for people to improve compressor
performance, greatly improve the efficiency of the compressor and save
energy. Therefore, there is a very good development prospectof the
application of electric linear compressor on new energy vehicles . At the
same time, it also raises higher request to the performance test of liner
compressor.
This article studies performance test base on the electric linear
compressor. First it introduces basic knowledge of liner compressor,such
as characteristics, working principle and structure.And it tells how to
design test bench by choosing appropriate sensor. Then, using LabView
software to design a set of linear compressor's test system. Finally,
using the acquisition card and test software collect all kinds of signals
of linear compressor, and using the test system for the signal analyzing
to finish the performance test of liner compressor.
Key words Electric linear compressor; Performance test; LabView
