What principles should be followed in the maintenance of three leaf roots blower? What principles should be followed in the maintenance of three leaf roots blower? The Roots blower has been used for a long time, and more or less there will be some problems. When we choose to repair the Roots blower, we should follow the following standards. Because the centrifugal blower that does not necessarily have common faults is necessary for maintenance!

1. Importance criteria

All used parts of Roots blower can be disassembled for inspection and found to be in the following conditions: first, the quality is good, or they can be used again even though they are damaged but not repaired; Second, there are shortcomings, but after repair, it is still able to Reuse; Third, it has great shortcomings. It cannot be repaired or has little value for maintenance. It must be replaced.

During the whole process of inspection, the parts to be repaired and replaced shall be repaired and replaced immediately, otherwise the inspection quality of the blower motor will be endangered. However, if we blindly follow the trend to carry out maintenance on non hazardous locations, or we would have been able to If the reused parts are removed and replaced earlier, it will lead to consumption and increase the maintenance cost. Therefore, it is clear whether the parts are repaired or replaced, and the overall standard of "must be repaired or replaced" should be followed.

2. Reliability criteria

Defective parts must be repaired and replaced, but whether to repair or replace them should follow the standard of "reliable use". Select the parts to be repaired. After the repair, the original manufacturing precision should be repaired or mostly repaired. Consider the technical standards of the whole equipment for parts. This provision is generally Including specification deviation, roughness, dimensional tolerance and surface strength of parts. Generally speaking, most of the shells, plate walls and rotors that are not seriously damaged can still be used after being repaired. Such defects are common Select maintenance; However, once the rolling bearing, transmission gear, skeleton seal and other parts are damaged, they cannot be repaired, which usually causes more inconvenience when they are used in a makeshift manner. Therefore, they are generally replaced during maintenance.

3. Economic standard

Able to Whether the repaired parts must be repaired rather than replaced should also be more economical. This kind of comparison is not only a comparison of the maintenance and replacement costs of parts, but also a measurement of the maintenance cost and the service time of maintenance.
