Specific implementation mode：
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1, the utility model discloses a kind of test system of magnetic suspension centrifugal compressor, in compressor 100
Shell on be preset with air entry 102, exhaust outlet 103, gas supplementing opening 104, motor cooling import 105 and motor coolant outlet 106,
Test system includes evaporator 1, condenser 2, economizer 3, freezing water storage tank 4, cooling water storage tank 5, cooling water pump 6, chilled water
Pump 7, hot water water mixing valve 8, cold water water mixing valve 9, water tower regulating valve 10, main expansion valve 11 and water tower 13, the exhaust outlet of compressor 100
103 are connected with condenser 2, and condenser 2 is corresponded to be connected with motor cooling import 105 and economizer 3, and economizer 3 passes through main expansion
Valve 11 is connected with evaporator 1, and economizer 3 is connected with gas supplementing opening 104；Evaporator 1 is connected with air entry 102, and condenser 2 is by cold
But water pump 6 is connected with cooling water storage tank 5；Water tower 13 is connected by water tower regulating valve 10 with condenser 2, and freezing water storage tank 4 passes through
Hot water water mixing valve 8 is connected with condenser 2；Evaporator 1 is connected by chilled water pump 7 with freezing water storage tank 4, and evaporator 1 is by cold
Water water mixing valve 9 is connected with cooling water storage tank 5；Water tower 13 is connected with cooling water storage tank 5.
Water tower 13 is placed in the upper end of cooling water storage tank 5, is equipped with liquid outlet in the bottom end of water tower 13, liquid outlet is located at cooling water
The upper end of storage tank 5.
When in use, the exhaust outlet 103 of compressor 100 is by piping connection condenser 2, and condensed refrigerant is from condenser
2 outflows pass through economizer 3 to be entered evaporator 1 after cold side pipeline and main expansion valve 11.Before entering 3 main road of economizer, another point
Two-way connects motor cooling import 105 and is used for cooling down the motor in compressor 100, enters 3 cold side of economizer all the way all the way,
Evaporation endothermic will be further subcooled by cold side refrigerant, then connect gas supplementing opening 104, return to the sencond stage impeller 107 of compressor 100
Import.
The gaseous coolant that evaporator 1 flows out is connect with the air entry 102 of compressor 100.The side water route of condenser 2 passes through cold
But water pump 6 is extracted out from cooling water storage tank 5, is squeezed into condenser 2 and is cooled down to refrigerant, is gone out after condenser 2 and is divided into three tunnels, and one
Road directly returns to cooling water storage tank 5, is radiated all the way into water tower 13 by water tower regulating valve 10, in addition a-road-through superheated water
