Abstract
The invention discloses an air quantity testing system comprising a gas collection port, a gas exhaust port and a fixed support. The gas collection port is connected with an upper sampling device through a fastener. The upper sampling device operates in cooperation with a lower sampling device. The lower sampling device is connected with an air quantity testing bin. An air outlet of the air quantity testing bin is provided with the gas exhaust port. By the mode, the air quantity testing system is provided, an air flow passes through a tested device in a right opposite mode, and the air quantity of the tested device is judged by detecting and comparing the air flow quantity of the upper portion and the air flow quantity of the lower portion of the tested device. The air quantity testing system has the advantages that testing efficiency is high, an operation method is simple and the device is convenient to maintain. By means of the air quantity testing system, economic benefits of enterprises are improved, and production of the enterprises is expanded.
