Mjere opreza za izbjegavanje kratki kratki in polikristalni silicij električni grijači

Mjere opreza za korištenje polikristalni silicij električni grijači:
1. When working, the voltage should not exceed 10 percent of the the rated value, the humidity should not exceed 95 percent , and the air should not contain corosive gases.
2. The ožičenje dio must be placed outside the grijanje sloj i izolacija sloj, i prizemljeno to avoid short circuits. In addition, it is necessary to avoid contact with corosive and explosive media during use to avoid dangerous accidents.
3. It should be placed in a dry place. If it is not used for a long time and the resistance is less than 1M Ω during application, it can be placed in a 200 degree oven for a few hours to restore normal operation. Alternativno, by reducing the voltage until the resistance is restored, the operation can begin.
4. It should be positioned well, and the heating part must be in contact with the heating part, and cannot be burned empty. Meanwhile, if dust is found during use, it should be promptly cleaned to avoid affecting the performance of the equipment and reducing its service life.
5. When korištenje, the electric grijanje cijev must not come into contact with water to avoid electric leakage accidents.
The zahtjevi for the sirovo materijal of protuprovalna zrak kanal električni grijači include:
(1) sastav of magnezij oksid in izolacija materijali treba meet the specificified requirements and be sušen prije upotreba.
(2) The Electric Grijanje Materijal Treba Use High Resistance Electric Grijanje Legura žica, A A Working Temperature of 400 degrees Celzijus i meet the specificified requirements.
(3) The material of the protective sleeve should be nehrđajući čelik cijev to can withstand toplinski i meet the specificified requirements.
(4) The inside of the protective sleeve tank should be keep clean and free from defects such as burrs. If there are burrs or oil stains, they should be Removed Without Any Residue.
