What safety issues do industrial fans need to pay attention to?
The production and manufacture of modern industrial fans are full of many safety hazards, and the equipment itself will also present such problems as living on the way to use and equipment. The following Hangzhou Yada Electromechanical Co., Ltd. introduces us to:
Primary sources of risk
Causes and processes of risk outbreaks are prone to incidents
1, industrial fan insulation performance does not meet the requirements, did not take maintenance measures, resulting in leakage of electricity. This situation may lead to electrocution.
2, the industrial fan's protective net cover was damaged or the net hole was too large, and the personnel accidentally touched the rotating fan leaf into the net cover. This situation generally leads to mechanical damage.
3, large-scale industrial fans did not repair in time, did not measure the insulation resistance regularly, resulting in insulation damage, personnel touch the charged parts. This situation may also lead to electrocution.
4, in the flammable and explosive site illegal operations, Spark or static electricity. This situation usually causes an explosion or fire.
Emergency response to incidents
1, found that large industrial fan display device loose, displacement, charged shell and other phenomena, should be imtely closed fan, and repair.
2, in the event of personal electric shock risk, should imtely close the power switch, rescue the electrocuted person, and should maintain the incident scene.
3, if the onset of mechanical damage, should be imtely bandaged, hemostasis and other treatment to prevent infection; Serious cases should be dealt with imtely at the hospital.
Third, the industrial large ceiling fan after multiple safety measures, the accidental fall of the fan or blade
1, the industrial large ceiling fan's electric fan suspension frame and steel structure roof after bolt fastening, extra wire rope wound between the roof H steel and suspension.
2, the frame of the motor and reducer has drawn 4 steel wire ropes connected to the roof, which can limit the vibration of the fan during work and provide two layers of maintenance.
3, the junction of the leaf shaft of the industrial large ceiling fan and the deceleration motor is connected by the use of reverse thread fastening and conical aluminum shaft lining.
4, the patent plan Y-type connecting arm is equipped with two layers of positioning devices to prevent the blade from falling.
5, the specially planned safety ring through the bolt and blade roots for two layers of connection
