What is the reason for the high current of Roots blower
There are various reasons for the high current of Roots blowers, and the following are possible reasons and their explanations:
1. Pipeline blockage:
When the outlet of the Roots blower is not smooth and the gas emission is blocked, it will cause the pressure inside the pipeline to rise, thereby overloading the motor and increasing the current.
For example, in the aeration process of sewage treatment, if the shutdown is not standardized, it may cause water to be sucked back and block the aeration disc, and the current will increase sharply when restarted.
2. Poor lubrication:
If the fan operates in a state of oil shortage, dry grinding of bearings and gear wear will increase the load on the motor, thereby increasing the current.
3. Incorrect operation:
Incorrect operations such as reversing the one-way valve or starting the gate valve before fully opening it may cause the motor to instantly overload, resulting in an increase in current.
4. Problems with the fan itself:
Individual manufacturers' Roots blowers may have quality issues, such as poor clearance between components and poor impeller balance, which can increase additional friction or damage, thereby increasing motor load.
5. Power issue:
Unstable power supply voltage or poor power quality may also cause an increase in the current of the Roots blower.
6. Environmental factors:
Environmental factors such as temperature, humidity, and altitude may also affect the operation and current of Roots blowers. For example, in high temperature environments, the heat dissipation performance of the fan may decrease, leading to an increase in motor temperature and thus an increase in current.
7. Electrical malfunction of the motor:
Electrical faults such as short circuits, open circuits, or leakage in motor windings can also cause an increase in current.
8. Other factors:
If the coal tar in the machine is severely bonded and water is brought into the Roots blower, it may also affect the normal operation of the fan and cause an increase in current.
To address the issue of high current in Roots blowers, the following measures can be taken for troubleshooting and handling:
1. Check if the pipeline is unobstructed and promptly clear any blockages.
2. Regularly check and add lubricating oil to ensure that the fan operates in good lubrication condition.
3. Strictly follow the operating procedures to avoid misoperation causing an increase in current.
4. Choose a reliable Roots blower and regularly inspect and maintain it.
5. Ensure stable power supply voltage and improve power quality.
6. Pay attention to the impact of environmental factors on the operation of the fan and take corresponding measures to improve it.
7. Regularly inspect the electrical components of the motor, promptly identify and address electrical faults.
If the above measures cannot solve the problem, it is recommended to contact professional technical personnel for maintenance and handling.
