In the whole process of application of roots blower, it is sometimes found that the current of roots blower is too high. Once the current of roots blower is too high, the motor load may endanger all normal operation of roots blower and a series of problems.
As the outlet of the fan is not clear, the air is blocked, the pressure rises, the motor forms overvoltage overload, the pipeline is blocked, and then the equipment ammeter rises. Misoperation of current overload may also cause problems during operation. For example, if the equipment is reversed, the valve is not fully opened, and this operation may cause the motor to burn instantaneously.
During operation, it shall be carried out according to regulations, and unnecessary troubles are prohibited. If there is no lubricating oil for the equipment, the fan will continue to operate without oil. Impellers will conflict, gears will wear each other, and then increase the load of the motor. It will only increase the load on the motor to accelerate the loss.
The problem of the fan itself is the quality problem of the factory. When installing the fan, many parts are poorly combined, which will form a rating conflict. Maintenance and parts replacement rules of Roots blower manufacturer, based on the preparatory work of blower fault analysis, confirm the repair location and scale, and prepare the parts that may need to be replaced. Prepare appropriate inspection items and measuring tools according to the structure of parts. According to the quality of the blower, the overhaul plan is formulated.
Implement safety measures. When removing precautions, the dimensions of important parts and the orientation of the equipment should be marked so that the check mark can be reset during assembly to prevent seizures. For example, measure and record the thickness of various gaskets, measure and record the clearance of various parts of the rotor, and summarize the corresponding symbols on the main gear, driven gear and tooth slot.
Before installing Roots blower, clean and check the parts to be used. For disassembled parts, the appearance of processing shall be protected and placed according to certain rules. Parts in the same part, such as bearing seat, bearing gland and adjusting washer of the same part, shall be put together. The missing parts shall be included in the special equipment. Matched applications should be stored together.
1. Pipe blockage
The common reasons are that the pipe is blocked, the fan outlet is unstable, the wind does not go out, the pressure rises, and the motor causes overpressure overload, which leads to the rise of the Roots blower ammeter.
2. Reasons for lubricating oil
If the lubricant of Roots blower is insufficient, the fan will continue to work without oil. The impeller failure friction and gear wear will increase, which will increase the motor load, which will only increase the motor load and accelerate the loss.
3. Misoperation
During operation, current overload may also be a problem. For example, if the check valve is installed in the opposite direction and the gate valve is not fully opened, this operation may cause the motor to burn instantaneously and should be carried out as specified during operation. Don't cause unnecessary trouble.
4. Problems with the fan itself
The fan factory has its own quality problems. When installing the fan, the clearance of many parts is poor, which will cause additional friction. In addition, some components may be damaged, increasing the load on the motor, and the fuse may blow.
In a word, if the current is too high, the roots blower motor will be in an overload state, regardless of the cause of the fan itself or the operation error. In daily use, in order to effectively avoid the failure of roots blower, we should follow the correct operation. Frequently stop and check the use method and process, and carry out maintenance and troubleshooting. This is an indispensable and effective method.
I believe that after reading the above contents, you should also understand the causes of overcurrent of Roots blower. I hope it will be helpful to you.
