Meter.But in actual production life, the application of reciprocating compressor is also very extensive.For reciprocating compressor, suction
Cyclically-varying can be presented with the keying of air valve in compressor in gas, therefore exhaust side is also easy to produce pulsation.If not being controlled, can go out
Situations such as existing subsequent compression machine discharge capacity measures inaccuracy, and damage measures component.Therefore, for reciprocating compressor type spy
Point, design are a kind of significant for the enclosed performance test stand of reciprocating compressor.
The existing compressor performance pilot system of comprehensive analysis, there are still following deficiencies：
1. existing performance test system is mostly based on open system, to compressing type selection, the experiment air inlet operating mode of working medium
Certain restrictions is respectively provided with, it can not be to certain high into press type progress Validity Test；
2. voltage reduction module spininess is designed centrifugal compressor in existing performance test system, only with pressure reducing valve or tune
Valve is saved to realize that system is depressured, but is not particularly suited for the type that the needs such as reciprocating compressor take into account pulsation requirement；
3. voltage reduction module is mostly using single valve, for a certain specific or a certain group of small range in existing performance test system
Type is designed, and test scope and power of test have certain restrictions, do not have for certain high high row pressure types of discharge capacity
Suitability；
4. existing performance test system is mostly using single main line, because pipe valve failure and other reasons cause during experiment
The possibility that system is breaking and causes danger is higher, and safety is insufficient.
In conclusion there is an urgent need for develop a kind of decompression for large reciprocating compressor enclosed Performance Test System for this field
Buffer unit is realized in the case where ensureing follow-up measurement accuracy Security of test and popularity to currently used reciprocating
The test of compressor type.
