9、使用中如发现净化空气中有粉尘溢出时，其原因可能是：⑴文氏通气管破裂

9. During use, if there is dust overflow in the purified air, the reasons may be: <br>⑴Venturi vent pipe rupture; <br>⑵Filter bag rupture; <br>⑶The upper and middle boxes are not tightly sealed and leak; <br>⑷Enter the middle box There is a sudden increase of excessive dust in the gas of the body, and the cause should be found out and measures should be taken to solve the problem. <br>10. The operator should strictly pay attention to the airtightness of the equipment, especially the degree of closed air of the closed air filter, to ensure the high efficiency of dust removal of the pulse filter.

9, if found in the purification of the air when dust overflow, the cause may be:<br>(1) Wen's breathalyser rupture;<br>(2) the filter bag is cracked;<br>(3) the upper and middle boxes between the seal is not strict and leakage;<br>(4) If too much dust is suddenly added to the gas entering the box, the cause shall be identified and measures taken to solve the problem.<br>10, the operator should pay strict attention to the sealing of the equipment, especially pay attention to the degree of closed air of the closed air, to ensure that the pulsed dust filter high efficiency dust removal.

9. In case of dust overflow in the purified air during use, the reasons may be as follows:<br>(1) the venturi vent was broken;<br>(2) the filter bag is broken;<br>(3) air leakage due to poor sealing between upper and middle boxes;<br>(4) if there is too much dust in the gas entering the middle box, find out the reason and take measures to solve the problem.<br>10. The operator should pay close attention to the airtightness of the equipment, especially the airtight degree of the air closers, so as to ensure the high efficiency of the pulse dust filter.<br>
