What should mining fan manufacturers pay attention to when conducting fan test runs?
Fan manufacturers should adjust in time if abnormalities are found during the experiment. Throughout the experimental process, all professionals should be on duty to ensure the safety of equipment operation. If the mining fan factory operating fan and its system ducts produce violent oscillations, operating parameters obviously exceed the standard, commissioning personnel should immediately order to stop running the fan, suspend debugging, analyze the reasons and propose solutions, and then continue to debug equipment.
The rubbish and debris around the equipment has been eradicated, and the scaffolding has been removed. Ensure that the test run site is clean, with outstanding lighting and unobstructed communication. All scaffolding that hinders the commissioning work has been removed. No flammable and explosive substances are allowed to be placed in the vicinity of the test run site, and complete fire-fighting facilities are provided. The exposed rotating parts should be equipped with protective covers or fences.
It is necessary for the mining fan manufacturer to monitor the changes in oil pressure, oil temperature, bearing temperature and oscillation of the fan to avoid malicious incidents such as tile burning. During the trial operation of the fan, all personnel shall not stay in the tangential direction of the fan rotation. Before the trial run, the motor insulation qualified, the incident button action is normal before starting the motor. Arrange to sort out the flue, duct, dust collector, furnace chamber debris, and inspection test. Pay special attention to the boiler induced draft fan into the air duct without welding rod and other hard slag. Tidy up welds, coatings and slag, close all manhole doors and inspection holes in the flue gas and air system.
During commissioning on site, it is necessary to wear a safety helmet. It is necessary for the person responsible for the work of the following perhaps mining fan manufacturers to dissect the site and eliminate the dangers of falling, electric shock, scalding, rotating mechanical distortion, etc.
