Non-Burning Brick Brick Machine: Advantages And Disadvantages Of Two Large Drive Units Of Belt Conveyor

The drive of the belt conveyor is the main source of power in its operation. To ensure the normal production of the belt conveyor, it is necessary to fully understand its drive, including its advantages and disadvantages. The following is a brief description of the advantages and disadvantages of the high-speed DC motor + reducer and the low-speed DC motor directly driving the drive roller of the belt conveyor.

High-speed DC motor + reducer: This drive mode has a speed control function, which is generally used on large belt conveyors that require speed control.

Advantages: Good soft start performance, linear controllable speed curve at start-up, linear controllable speed curve when parking, good electric braking performance, stepless speed change, excellent controllable performance, closed loop control and high reliability.

Disadvantages: the price is very expensive, the thyristor rectifier system is complex, the electronic control equipment has a large area, the power factor is low, the DC motor has a slip ring, the brush wears large, the maintenance workload is large, and there is no explosion-proof type at the coal mine. Not available.

The low-speed DC motor directly drives the driving roller of the belt conveyor: the low-speed DC motor directly drives the driving roller of the belt conveyor, which is a driving method with a speed regulating function, which is generally used to require a speed regulating function, and the motor single machine power is greater than 1000 kW. On the belt conveyor.

Advantages: Excellent soft start performance, linear controllable speed curve at start-up, linear controllable speed curve when parking, good electric braking performance, stepless speed change, excellent controllable performance, closed loop control, no reducer, reliability high.

Disadvantages: the price is very expensive, the thyristor rectification system is complicated, the electric control equipment has a large area, the power factor is low, the DC motor has a slip ring, the brush wears large, the maintenance workload is large, and the current high-power non-explosion-proof type is in the coal mine. It can't be used underground.
