Study on Using Independently Developed Equipment for Mines Axial-flow Main Ventilator Performance Test
Performance test for operating mines ventilators are generally on-line,hence the test effect mainly depend on a full-prepared anemometry that should find a section where ventilating current is relatively still.While in the condition of on-line test,the only appropriate test site is in the annular contraction section of the leading device; but this section does not have an enough sectional area to fixate Pitot tubes.Therefore,the key to measure the performance of the ventilator is to develop a special equipment to transmit the wind pressure,and replace old Pitot tubes to install in the leading device.This paper introduce the design principle and manufacture method of this independently-developed wind-pressure measuring equipment,meanwhile calibrate the pressure transmissions effect with standard Pitot tube and put this equipment in practical.After field measurement,the equipment can effectively transmit wind pressure,and its characteristic performance curve tallies with the standard one,therefore attain the final goal of measuring a ventilators wind pressure.Furthermore,in different specifications of ventilator,the equipment can adapt itself to different physical dimensions of annular contraction section.All in all,the equipment is scientific,reasonable and easy to be popularized in the mechanical ventilation mines.
