ڌماڪي جي پروف موٽر جي مرمت ڪرڻ وقت ڇا ڌيان ڏيڻ گهرجي

1. ڌماڪي جي ثبوت واري موٽرز کي سنڀالڻ: ڌماڪي جي پروف موٽرز کي الڳ نه ٿيڻ گهرجي يا اتفاق سان ٻيهر گڏ نه ڪيو وڃي. جڏهن سار سنڀال لاء dismantling, it’s crucial not to use the explosion-proof surface as a fulcrum for a pry bar, ۽ ڌماڪي واري مٿاڇري سان ٽڪرائڻ يا ٽڪرائڻ کان پاسو ڪريو.

2. ختم ڪرڻ جو عمل: موٽر کي ڌار ڪرڻ لاءِ, first remove the fan cover and fan. پوءِ, use a socket wrench to remove the end cover and bearing cover bolts. اڳيان, strike the shaft extension radially with a wooden or copper rod to separate the shaft sleeve from the bearing seat, and finally, remove the motor rotor. When disassembling parts, ensure that the explosion-proof surface faces upward and is covered with rubber or a cloth pad. Be careful not to lose bolts or spring washers.

3. Painting and Assembly: When applying insulating paint or assembling, clean any insulating paint or dirt adhering to the explosion-proof surface. Avoid scraping with hard objects like metal, but it’s permissible to smooth uneven areas with an oilstone.

4. Repairing Explosion-Proof Surfaces: If the explosion-proof surface is damaged, use lead-tin soldering material HISnPb58-2 and a 30% hydrochloric acid flux (for steel parts), or use tin-zinc soldering material with 58%-60% tin content, with a flux made of 30% ammonium chloride, 70% zinc chloride, ۽ 100-150% water mixture (for cast iron parts). Ensure solid fusion between the welding material and the part, and smooth out any protrusions to a flat, polished finish.
Preventing Corrosion: To prevent rust on the explosion-proof surface, apply machine oil or a 204-1 type anti-rust agent.
