What are the causes and solutions of Roots blower failure?

[Roots blower fault causes and solutions]

1、 Introduction

Roots blower is a kind of centrifugal fan commonly used in industrial field, which is widely used in air compression, liquid transportation, waste gas treatment and other fields.

However, in the process of use, Roots blower will also have some faults, affecting its normal operation.

2、 Cause of fault

1. Bearing fault

Bearing is an important part bearing load during the operation of roots blower. If the bearing is damaged or severely worn, it will lead to unstable operation or even stop operation of roots blower.

The main causes of bearing failure include poor lubrication, bearing wear, bearing overheating, etc.

The solution to this problem is to regularly check the lubrication of the bearing, replace the worn bearing in time, and maintain the normal temperature of the bearing.

2. Fan blade fault

The blades of Roots blower are the key parts for compressing and transporting gas or liquid. If the blades are broken, deformed or worn, the efficiency of Roots blower will be reduced, or even it will not work normally.

The main causes of blade failure include poor quality of blade materials, too long use time of blades, etc.

The way to solve this problem is to regularly check the condition of blades and replace worn or damaged blades in time.

3. Motor fault

The motor is the power source of Roots blower. If the motor fails, the Roots blower will not work normally.

The main causes of motor failure include short circuit of motor winding, high temperature of motor.

The solution to this problem is to regularly check the operation of the motor, maintain the normal temperature of the motor, and replace the damaged motor in time.

4. Overload fault

Overload means that the load borne by Roots blower during operation exceeds its design capacity.

When Roots blower is overloaded, motor overheating, bearing damage and other faults will occur.

The causes of overload fault mainly include changes in working conditions, sudden load increase, etc.

The solution to this problem is to reasonably arrange the working conditions of Roots blower to avoid the load exceeding its design capacity.

3、 Solution

1. Regular maintenance

Regular maintenance is an important means to prevent failures.

The service life of Roots blower can be effectively extended and the probability of failure can be reduced by regularly checking all parts of Roots blower, timely finding problems, and carrying out maintenance and replacement.

The frequency and content of regular maintenance shall be determined according to the use condition and working environment of Roots blower.
