The first stop valve 8, subject valve 9 and second are sequentially installed with door experiment bypass duct 21, the valves test bypass duct 21
Differential manometer 5 is installed on stop valve 10, the subject valve 9, in addition, in order to realize the temperature monitoring to motor 33, fused salt tank 32,
The detection means of the present embodiment also includes device for detecting temperature, pump for liquid salts and valve due to test object to be run under hot conditions
Door, the under the high temperature conditions stable influence on pump valve such as deformation, vibration, noise, Temperature Distribution of the parts of each several part
Very big, the detection means of the present embodiment is also added into vibration, noise-measuring system.
It is preferred that, the liquid level is calculated as ultrasonic level gage.The pressure gauge is nitrogen seal pressure table.
Testing specific method is：Solid-state fused salt is prepared according to real working conditions and is added by barrel 29 in fused salt tank,
Monitor the liquid level 18 in fused salt tank 32 at any time by liquid level gauge 20；Then test pump 14 is arranged in pump mount base 36, opened
Need fully to heat the fused salt in fused salt tank 32 before dynamic test pump 14, it is ensured that the fused-salt medium in fused salt tank 32 fully melts,
Prevent that there is the fused salt not melted will test pipeline blockage.The stop valve 8 of flow control valve 7 and first, the second stop valve 10 are closed,
Open service valve 12.Test pump 14 is opened after testing equipment temperature stabilization, flow valve 7 is opened after pump operation to be tested is stable,
Under the conditions of allowing pilot system after operation certain time under the conditions of flow valve 7 is in small guide vane to the progress different flow of test pump 14
Performance test vibration, noise are tested and carry out data acquisition simultaneously.When testing high temperature subject valve 9, first
Check-valves 6 and flow control valve 7 are closed, the first stop valve 8, the second stop valve 10 and subject valve 9 is opened, is then turned on fused salt
Pump 14, treats that the stable relief pilot system of pump for liquid salts runs certain time under the conditions of flow valve 7 is in small guide vane, then to subject valve
9 carry out the performance test under different flow.By the way that the high temperature resistant thermometer in device for detecting temperature is to motor side 2 and melts in experiment
Salt cellar 13 carries out temperature monitoring, wherein to the wall temperature monitoring point 13 in the monitoring position of fused salt tank wall temperature such as Fig. 1, to the prison of liquid temperature
Location puts the liquid temperature monitoring point 17 seen in Fig. 1, to temperature monitoring point 2 at the motor in the monitoring position of motor such as Fig. 1, to motor
The temperature monitoring purpose at end is whether the temperature for examining motor side is higher than safety value, and being monitored purpose to the temperature of fused salt tank is
Fused salt does not solidify the safety with fused salt tank in guarantee experimentation.During vibration, noise testing, monitoring point is as in Fig. 3
Shown in the monitoring point 27 of different height and circumferential monitoring point 28.Wherein, monitoring point more than fused salt tank deck is vibrated, noise is surveyed
Monitoring point below examination, fused salt tank is only to vibration-testing, and the test of vibration and the monitoring of noise immediately to pump performance is also simultaneously
The safety that test system is run is monitored.
Because the remaining high-temperature molten salt of pressure gauge 3 and the two instruments of flowmeter 4 centre can condense, so as to influence next time
The normal operation of pressure gauge 3 and flowmeter 4 during operation, condenses to protect the two instruments to occur without fused salt, and normally starts,
After the completion of experiment, the valve of return duct 11 and service valve 12 are opened, remaining high-temperature molten salt in loop is recovered to fused salt
In tank 32, heating tube 15 is closed again after test pump 14 is taken out.
