Embodiment

[0058] figure 1 It is the control system diagram of the compressor stall performance test bench. When testing the stall performance of the compressor according to the requirements, the test parameters should be preset in the display module.

[0059] Select the power supply according to the model of the compressor under test: AC380V or AC220V voltage,

[0060] Select the test type: durability test or phase loss test,

[0061] Select the phase loss test type: loss of U phase, loss of V phase, loss of W phase.

[0062] Set the total test time, set the total number of tests, and set the protection time of the protector.

[0063] After the parameters are set, all the parameters are read by the data processing module and processed, and the data is processed into a secondary signal and input to the control module, and the control module is connected to the compressor protector, alarm module, timer, counter, compressor .

[0064] When the compressor stall test is carried out accor...

Abstract

The invention discloses a system and method for controlling and monitoring a locked-rotor of a compressor locked-rotor performance test bench. The system comprises a data processing module, wherein the data processing module is in parallel connection with a data recording module, is in serial connection with a display module through a communication module, and is in parallel connection with a control module; the control module is in serial connection with a component; the component is in parallel connection with an overcurrent alarm apparatus and a low-voltage alarm apparatus; the overcurrentalarm apparatus and the low-voltage alarm apparatus are in parallel connection with a feedback circuit; and the other end of the feedback circuit is in serial connection with the data processing module. The system and method can accurately determine the locked-rotor of a compressor in the compressor locked-rotor performance test bench, need to manually restore a protector, end the test and recorddata, realizes the automatic operation of the locked-rotor performance test bench, improves the detection efficiency, and avoids the test failure caused by misjudgment.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a stall control and monitoring system and method of a compressor stall performance test bench. Background technique [0002] The low-temperature environment in industrial production is realized by the refrigeration system. The compressor is the core of the refrigeration cycle system. Once the compressor fails, it will not only cause damage to the refrigeration system, but the leaked refrigerant will also cause environmental pollution. Before the compressor is put into use, performance tests such as stalling, durability, and cooling capacity shall be carried out in accordance with national standards. The stalling test means that when the compressor is powered on and running normally, the rotor is locked due to external factors and the sudden speed is Zero, the locked rotor causes the compressor current to rise instantaneously, and the current at this time is the locked rotor c...
