Ventilation fan operation
1. During the use of ventilation fans, operation records should be prepared to record the operation status of the fans in accordance with relevant regulations, including:
(1) Ventilation fan start time and shutdown time, reasons for shutdown.
(2) Environmental temperature, humidity, and atmospheric pressure.
(3) The working voltage, current, temperature of each bearing, and motor temperature of the motor should be checked immediately if any items exceed the standard.
(4) The air volume and pressure of the ventilation fan.
(5) The time, quantity, and brand of lubricating grease for bearing replacement.
(6) Abnormal issues discovered during regular inspections and troubleshooting situations.
The ventilation fan is equipped with non-stop air injection and oil discharge devices, which can add lubricating oil during operation. When the machine is shut down, the oil discharge port cover can be opened to discharge waste oil. The ventilation fan can transport underground air containing explosive gases of methane in the medium, and is generally designed for horizontal installation with a designed service life of not less than 20 years. The operating time before the first major overhaul is not less than 9000 hours. The impeller barrel of the ventilation fan is equipped with H62 brass protective ring, which can be used with two processes: riveting and explosive welding. It has passed the friction spark safety test of the National Coal Mine Dust Prevention Ventilation Fan Safety Quality Supervision and Inspection Center, solving the hidden danger of fire or explosion caused by blade collision during operation in dirty wind. The fan blades and the inside and outside of the casing have undergone multiple anti-corrosion and moisture-proof treatments, allowing the fan to operate for a long time in a humid environment, effectively solving the problem of corrosion caused by other conditions on the fan.
