The compressor start-up test bench is designed based on the relevant testing requirements proposed by customers and in accordance with the requirements of the GB/T9098-2008 standard. It conducts continuous voltage-rising start-up tests and continuous voltage-dropping start-up tests on the tested compressor under a relative test ambient temperature. By analyzing test data such as different test ambient temperatures, electrical parameters, and pressure parameters, the compressor's start-up condition can be evaluated, and the comprehensive performance of the compressor under different testing environments can be determined. It is suitable for production line and laboratory testing, and the equipment is easy to operate, requiring no specialized personnel
