1、 Cause of damage

"Roots blower belt" It is easy to be damaged due to the following reasons:

1. There are problems in the quality of the belt and the durability is not good enough; 2 The excessive tension of the motor results in the excessive load and tension of the belt; 3. The pulley is not in a radial direction and there is deviation; 4. The belt specification is not correct, resulting in mismatching;

2. Treatment method:

1. First, check whether the fan pulley and motor pulley are in the same radial position; 2. Check the tension degree of the fan belt. Hold the pulley by hand and rotate it along the vertical belt direction to check that it can rotate 90 degrees. If the rotation is less than 90 degrees, it indicates that: if the tension degree is too high, adjust the position of the motor and head to reduce the tension. 3. Use well-known brand belt, such as gates belt in the United States, and reject the fan belt with poor quality.

Belt in Roots blower In addition to the usual replacement of the belt, the gear oil in the fan should also be replaced regularly. The viscosity of the gear oil will be reduced after a long time. Therefore, it is necessary to replace it in time. Here are the precautions for use:

The lubricating oil of Roots blower is mineral oil, such as hydraulic oil and antirust turbine oil. The lubricating grease is No.3 MoS2 lithium grease or silicon series grease. Synthetic oil, grease or other suitable oil products are used in special occasions. Water, resin and tar are not allowed in lubricating oil.

When the roots blower is running for the first time, it should be filled with the specified brand of lubricating oil to the oil level. If it is grease lubrication, it has been filled. Pay attention to the oil level and oil temperature during the first 24 hours of operation and prevent oil leakage.

The first change of lubricating oil should be carried out after the roots blower has been running for 500 hours, and the grease should be replenished regularly. After that, the lubricating grease should be changed every half a year (4000 hours). The specific replacement cycle can also be determined according to the service conditions or the actual oil quality identification.

The correct oil level of lubricating oil is that the center line of oil mark is slightly higher than 3-5mm under static state. The oil level is between the two oil marks. Too little oil will lead to poor lubrication of gears and bearings, and excessive oil filling will make the oil temperature too high.

The oil temperature should be detected regularly, and the oil level and shaft seal oil leakage should be observed every week. Oil replacement or replenishment should be carried out when the blower is stopped.
