Before the actual operation is operated, the high voltage isolation of the three -phase and five -line line should be pushed with the insulating rod, and the three -phase AC voltage is not balanced and everything is normal.In the second place, the knife gate is closed, and there are oil switches if you open it.After this work is over, you can gradually operate the stainless steel motor.
The grounding device of stainless steel fan case or motor wind cover must be reliable. It is strictly forbidden to rotate in the reverse. It is strictly forbidden to operate from constant current volume. It is strictly forbidden to run the stainless steel fan rolling bearing for less than 1,000 minutes. It is forbidden to maintain maintenance fan during operation.Preparation before the installation of stainless steel fan comes from:
1. Whether the product packaging design should be inspected before the fan is dismantled, is it intact and loss of damage? Can the basic parameters of the factory nameplate of the fans be in line with the companys regulations, whether each carrying accessories can be more detailed.Stainless steel fan is suitable for high -rise housing management methods of enterprises, engineering construction, underground waterproof engineering building and tunnel construction, drying houses and other ventilation or high temperature natural ventilation.Under 280 ° C at a high temperature of 280 ° C, it is more than 30 minutes of continuous operation, and the material is not destroyed for 20 minutes/time at a standard temperature of 100 ° C. It is an idealized natural ventilation infrastructure construction.
2. Carefully observe whether the fan is transformed or destroyed during the entire logistics transportation process. Whether the solid parts are loose or falling down, is there any adverse situation of the centrifugal leaf wheel and check the wind mechanism.If you find abnormal conditions, repair before application.
3. Use a 500V meter table to measure the ground resistance of the fan case and the middle of the motor winding group, and its value should exceed 0.5 mega Euro table; otherwise, the dry motor winding should not be less than 120 degrees in the dry process.
4. Prepare all raw materials, tools and sufficient interior space required for installing the fan in advance.
The above is the precautions of stainless steel fan in the usual application. For more relevant information, please pay more attention to us ——
