FDGM type cold and hot air isolating door Electric
Product description
FDGM electric cold and hot air isolating door is a new product developed on the basis of FQMM electric cold and hot air isolating door.Isolation door is an important auxiliary equipment of boiler, installed in thermal power plant boiler cold, hot air channel need to shut off isolated occasions, such as: coal mill inlet duct.The product works reliably, opens and closes flexibly, the seal is tight, fundamentally solves the previous isolation door closes not strictly, closes the time is too long the shortcoming, greatly facilitates the equipment switch and stops the service inspection repair, has been widely used in the country each big power plant.
Main features
1. Horizontal, vertical, inclined and vertical installation can be carried out depending on the user's site conditions.
2. Interlock design is adopted for door opening, closing and locking, which is convenient for centralized computer control. For convenience of maintenance and special needs, manual operation can also be conducted on site.
3. The equipment is heat treated as a whole, which does not deform under large temperature difference. It adopts novel sealing material, good sealing performance and abrasion resistance.
4. Optimize the design, so that the thermal isolation door in the use of the process to reduce the guide rail ash phenomenon, reduce the failure rate, reduce the maintenance cost and maintenance personnel labor intensity.
Technical parameters
1. Model: FDGM-A(length) *B (width) *H (height)H damper thickness is generally 560mm.
2. Medium: cold and hot air
3. Design temperature: < =400 ℃
4. Under pressure: < =30Kpa
5. Opening and closing time: When the wind density < =1m, opening and closing time < 4.7 minutes;When the wind density < =2m, the opening and closing time < 5.6 minutes;When damper width < =3m, opening and closing time < 6.95 min.
6. Lock time: < 45S
7. Voltage: ac 380v
