Main fan management system
1. Monitoring instruments such as water column, ammeter, voltmeter, power meter, bearing thermometer must be installed in the main fan room. The main fan is responsible for the full-time driver and fills in the operation records on time.
2. Before the newly installed main fan is put into production, the Tianjin fan manufacturer must continuously run for at least 72 hours and perform fan performance tests. The performance of the main fan in operation must be measured every five years.
3. The main fan must be equipped with a backup fan of the same capacity. When the main fan is out of service due to solid conditions, the backup fan must be started within 10 minutes. Otherwise, all power in its area must be cut off and the personnel in the mine should be immediately removed. All of them were withdrawn into the air intake lane, and after the air flow returned to normal, gas was discharged in accordance with regulations.
When starting the backup fan, it must report to the mine dispatching room, the fan, and notify the electrical, mechanical, safety, and ventilation departments.
4. The anti-wind facilities of the main ventilator shall be organized by the mine manager in the mechanical and electrical, ventilation, technology, production, safety and other departments. Which one of the Tianjin ventilator manufacturers is good, shall be checked at least once a quarter. The inspection items include: ventilator and its starting equipment, suction room, explosion-proof door (risk) fixed facilities. If the downhole door and anti-freezing facilities are found in the underground, the problem will be dealt with in time. An anti-wind exercise is conducted once a year. When the ventilation system of the mine changes greatly, an anti-wind exercise is carried out at any time.
5. The leakage conditions of the anti-wind facilities and explosion-proof doors of the main fan room shall be checked at least once every quarter by the mine manager. The interval between headwinds should not exceed 18 months.
6. The operation angle of the main fan must be approved by the chief miner.
7. During the single machine operation of the ventilator for some reason, special measures must be formulated. The operation time of the single machine within one week must be approved by the chief miner. If the time exceeds one week, it must be submitted to the higher authority for approval.
Fan performance parameters
The performance parameters of the fan mainly include flow, pressure, power, efficiency and speed. In addition, the size of noise and vibration is also the main technical index of the fan. Flow is also called air volume, which is expressed by the volume of gas flowing through the ventilator per unit time; pressure, also called wind pressure, refers to the increase in pressure of gas in the ventilator. Min; power refers to the input power of the fan, that is, the shaft power. The ratio of effective fan power to shaft power is called efficiency. The total pressure efficiency of the fan can reach 90%.
Future development trend of fans
The future development of the fan will further improve the aerodynamic efficiency, device efficiency and use efficiency of the fan to reduce power consumption; replace the large centrifugal fan with a shaft-flow fan with adjustable blades; reduce fan noise; improve smoke exhaust, Abrasion resistance of dust exhaust fan impeller and casing; realize variable speed adjustment and automatic adjustment.
