Roots blower is widely used in the pneumatic conveying system of ceramics, building materials, aquaculture, food and other industries. It is used to transport air and various neutral gases. The Roots blower also has the condition of generating overcurrent when it is used. Because the air outlet of the fan is not smooth, the pipeline is blocked, the air is not discharged, and the pressure rises, the motor is overloaded.
Overpressure and excessive wear cause the equipment ammeter to rise. Incorrect operation of the operating current may overload or appear in operation. For example, the check valve of the device is installed reversely when it is in reverse direction, and the gate valve is operated before all the valves are installed. This operation is likely to be the cause of the burning of the motor. The operation should be carried out according to the regulations, without carelessness, to avoid unnecessary trouble.
If the lubricating oil of the equipment is insufficient, the fan will be in a state of oil shortage. If we continue to work, the impeller problem conflicts, when the gears are worn and added, the motor load increases, the motor burden increases, the acceleration loss increases, and the fan itself has problems. The fan of Roots Blower Factory has its own quality problems. If the gaps of many parts are not appropriate when installing the blower, the rated conflict may occur.
In addition, some components may be damaged, adding motor load. The fuse has melted. There is a problem with the air outlet, if it is windy. If it does not go out, the pressure will rise, making the motor load level, and then the current will produce too much. The selection of Roots blower frequency converter must be based on the stable torque load. For the 45kW Roots drum fan, the rated current of the motor is 84, and the ACS604-0100-375kW frequency converter is selected.
Under the general service load condition, the power of imported motor is allowed to reach 7500kW. The power under heavy load is 55 kW. The output current within 10 minutes is 168A, twice the current delivered by the motor. The output current within 15 seconds can reach 224A, 2.65 times the rated current of the motor. The overload requirements can be met instantly.
Because roots blower is widely used, there are many domestic roots blower manufacturers, but the production technology department of each manufacturer is the same, so the quality of the factory roots blower also has a certain gap. Remember, the quality of roots blowers is not guaranteed by the high price. Because of the backward technology and equipment, small factories need more cost and time to produce roots blowers of the same model, or even worse equipment quality. But the cost is high, so the price is more expensive than other manufacturers.
I believe that after reading the above, you should also know how to judge the quality of Roots blower. I hope it will be helpful to you.
