青海福彩网 Before the start of ventilation equipment, the fan inlet control air door should be closed tightly to prevent misoperation and start with load. Shandong ventilation pipe processing check lubrication oil level is normal, cooling water supply, the coupling is intact, whether the closed door maintenance. Characteristics of ventilation ducts:
1, stainless steel plate wind pipe corrosion resistance is strong, the inner wall is smooth, the same thickness of stainless steel plate wind pipe pressure capacity and hardness are greater than galvanized pipe duct. Stainless steel tube has a good finish, easy to clean, high appearance. But the cost is also high.
2, galvanized steel sheet wind pipe is the air conditioning, ventilation and smoke exhaust system in the application of the most traditional and most widely used products. Galvanized steel sheet air pipe inner wall is smooth, small resistance, good air tightness, high bearing strength. The steel pipe air duct is easy to be made on site, and closely matched with civil engineering, so it can be used in very complicated ventilation engineering. The cost of galvanized steel pipe is lower than that of stainless steel plate, so it is widely used. The galvanized steel sheet air pipe is widely used in all kinds of ventilation and air conditioning system.
There are two kinds of ventilation ducts, round and rectangular, which can produce all kinds of pipes of various shapes and sizes according to the different needs of users.
3, the way of making:
Make the angle (or angle) and air duct flange flange ventilation pipe. Angle iron flange is a traditional way of making, long production cycle, low efficiency. Generally suitable for small workshops.
In this paper, the processing by the Shandong friendship ventilation pipeline dedication. More related knowledge: Please click http://www.qdkailun.com/ we will use the most advanced technology. The most sincere attitude, to provide you with the most comprehensive service. More related knowledge and we will continue to offer. Please look forward to.
