Reasons and Solutions for Fragile Belt of Roots Blower

Reasons and Solutions for Fragile Belt of Roots Blower

Reasons for easily broken belt of Roots blower:
1. First of all, consider the high speed and high temperature of Roots blower.
2. The distance between the head and motor of Roots blower is too large and the belt is tight.
3. The belt does not match the V groove of the pulley, so it can not withstand the load fracture after wearing.
4. Active pulley and driven pulley are not parallel, resulting in serious friction between belt and groove on one side, and can not bear load fracture after wear.
5. Heavy load, long-term overload operation of belt is easy to break.
6. Roots blower nose and motor pulley are not concentric, different axes.
7. Belt quality problems.

Measures to prevent the belt of Roots blower from breaking.
1. Roots blower must start without load before running. After starting, it should be loaded. After running, it can generally avoid triangular belt breaking.
2. The pulley between the motor and the blower should be parallel, which is a key point. If not parallel will also affect the operation of the triangle belt, easy to fall off. In addition, the diameter of the pulley should meet the standard, which directly affects the service life of the triangular belt. When processing, the diameter of the pulley is larger, which can better reduce the loss of the triangular belt.
3. If the triangle belt slips, it may cause the temperature to rise too fast, which will make the rubber of the triangle belt aging, or even break, so we must check whether the triangle belt will slip in normal use.
In addition, we also need to strengthen the maintenance of the triangular belt, which can effectively prolong the service life of the belt and ensure the normal use of Roots blower.
3. Specific cases and solutions:
1. Belt relaxation due to overheating of Roots blower
There are many reasons for overheating of Roots blowers, such as pipeline blockage, oil leakage, impeller friction, etc. Overheating of Roots blowers will transfer heat to the belt, resulting in the relaxation of the belt, causing the slippage and fracture of the belt of Roots blowers. In this case, we need to solve the overheating situation of Roots blower first. In the inspection process, we can eliminate the pipeline blockage, leakage and impeller friction. Some of them can be eliminated by ourselves. In view of the friction situation of Roots blower impeller, we need to disassemble the blower, and then assemble it. We need to have professional maintenance skills.
2. Sudden rupture of Roots blower
Some customers found that the belt suddenly broke in the process of using. This situation needs to be determined according to the specific situation. The situation that caused the sudden rupture includes: poor quality of belt, deviation of pulley, etc. Case: We have a customer, when installing Roots blower, the base screw was not tightened. After Roots blower was running for a period of time, the screw loosened, resulting in blower and motor. There are deviations between them, resulting in uneven force on the belt, and the situation of breakage. In this case, rigorous installation, timely inspection in use, and timely solution to the loosening of the screw.
3. Quality Problems of Roots blower
Among the maintenance customers we received, one such customer, whose roots blower belt was always broken, broke off in a few months, and frequently replaced. After checking by technicians, it was found that the motor of Roots blower was not on the same vertical plane with the nose, resulting in the motor deviation of the nose, running for a long time, and the belt appeared soon after use. In the case of relaxation and fracture, the nose and motor should be adjusted to the same vertical plane, and then the belt should be replaced.
