Measurement and Analysis of Performance of 2# Main Ventilator of East Two Shaft in Yaoqiao Coal Mine

Abstract

According to the existing conditions of the fan installation, we used precision barometer equipment and static pressure method to make a performance test about anti-explosion extraction axial fan in East Two Shaft under the condition of no shut down. According to the parameters of the test, we drew the performance curve of output power, wind pressure, efficiency and air volume about main fans of East Two Shaft in Yaoqiao Coal Mine. By measuring the results and analyzing data, it indicates that the main ventilator is in a good performance to meet the needs of air volume of East Two Shaft. To ensure the safe and economic operation of the main fan, the corresponding improvement measures aiming at the existing shortcomings of the ventilation system of East Two Shaft are put forward. The test method and results of the ANN-2500/1250 fan performance test have certain reference significance for the test of the similar axial fan.
