The economic benefits of using variable frequency speed control technology are remarkable. Our company has 65 water supply pumps and 38 main fan fans. Since 1998, some frequency pumps and main fan fans have adopted frequency conversion speed control technology, and have received good economic benefits. Taking a 5D main fan as an example, our company has a variety of fixed fan and water supply pumps, 103, most of which are early installation equipment, outdated equipment, loud noise, complex electrical control system, low technical performance, equipment High energy consumption, many hidden dangers, affecting safe production, restricting the high productivity and efficiency of the mine. Since the use of variable frequency speed control technology, the original working environment and surrounding environment have been greatly improved, and the labor intensity of the staff has been reduced.

1. Reduce the noise of the equipment room. After the main fan and water pump use the frequency conversion speed control device, the running speed of the motor, fan and water pump is reduced, and the noise is also reduced. According to the noise measurement of the main fan room of Weijiadi mine belonging to our company, when the air volume is directly adjusted by the damper, the speed of the fan and the motor are respectively the printing mountain, the noise in the machine room is more than 95 songs; when the hydraulic coupling is used for adjustment The motor speed is Langa m, the fan speed is 280 impressions m, the noise in the machine room drops to 70-80 mountains; when the frequency conversion speed regulation technology is adopted, the noise in the equipment room drops to 65-70db. After the application of the frequency conversion speed regulation technology, the labor intensity of the workers is reduced, and the degree of automation of the equipment is improved. The original air volume adjustment and flow regulation were all completed by manual operation of the damper or gate, and now it is changed to automatic operation. The automatic measurement is realized by sensors such as flow, pressure, voltage and current, and the centralized control of the computer automatically completes the collection, summary and adjustment of various data according to actual needs, and implements automatic management. 3. After applying the frequency conversion technology, the production is more safe and reliable. The motor realizes soft start, greatly reduces the starting current, avoids the circuit insulation damage and the damage of the electronic control equipment caused by the excessive starting current of the motor, makes the fan and the pump run smoothly, prolongs the service life of the equipment and reduces the repairing capacity. , reducing the accident rate.
