Factors causing excessive current of roots blower

Source: Roots blower manufacturer Published on: February 24, 2022 Hits:

Roots blower The pressure is related to the current. At the same speed and voltage, the greater the power of roots blower, the greater the pressure generated. Power=voltage X current, that is, at the same speed and voltage, the greater the current, the greater the power, and the greater the pressure.

Because the fan outlet 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 run 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 result in 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. Is there no lubricating oil at all parts of Roots blower; Roots blower needs regular maintenance. When it works in the state of oil shortage, the friction will increase and the motor load will increase, resulting in excessive current.

2. Whether the roots blower has smooth air outlet; If the wind beat cannot go out, the pressure will rise, which will also increase the motor load, resulting in excessive current.

3. Quality problems of roots blower; Poor clearance of many parts will cause additional friction. In addition, some parts may be damaged, increasing the load of the motor, and causing the fuse to blow.

It is inevitable that a fault occurs in the use of the three blade roots blower. In order to effectively avoid the fault of the roots blower, we should follow the correct use method in the operation and do a good job in daily maintenance.
