Several principles should be mastered when Roots blower needs maintenance?

The repair of Roots blower is a troublesome thing, especially when there is no technical team, processing equipment, repair equipment and testing equipment. This will not only affect the normal use, but also spend more money to repair. Let's talk about it, Roots blower is in need of maintenance during use, and the following principles need to be mastered.

1. Maintenance necessity principle of Roots blower:

All used parts of Roots blower can be disassembled for inspection in the following cases: first, the quality is good, or they can continue to be used without repair despite wear; Second, there are defects, but they can still be used after repair; Third, there are major defects that are difficult to repair or of little value for repair, and they need to be replaced.

During the inspection, the parts to be repaired and replaced shall be repaired and replaced in time, otherwise the inspection quality of the blower will be affected. However, if the parts that have no impact are repaired blindly, or the parts that can continue to be used are replaced in advance, it will cause waste and increase maintenance costs. Therefore, the principle of "repair and replacement only when necessary" should be followed in determining whether to repair or replace parts.

2. Maintenance reliability principle of Roots blower:

Defective parts need to be repaired or replaced, but the principle of "reliable use" should be followed. For the parts selected for repair, the original manufacturing accuracy shall be restored or basically restored after repair to meet the technical requirements of the whole machine for parts. These requirements usually include dimensional error, surface roughness, geometric tolerance and surface hardness of parts. Generally speaking, the casings, wallboards and rotors with less serious wear can be used as usual after repair, and such defects are usually repaired; However, once the bearing, gear, oil seal and other parts are damaged, it is difficult to repair them. Reluctantly using them often brings more trouble, so they are generally replaced during maintenance.

3. Economic principle of Roots blower maintenance:

Whether the repairable parts should be repaired rather than replaced, and the economy of repair and replacement should also be compared. This comparison is not only to compare the repair and replacement costs of parts, but also to weigh the repair cost and the service time of repair. After the maintenance price of the fan is obtained, a comprehensive comparison should be made. If you want to know the fair price, you can consult Xinqian Shun Fan. You should not only compare the maintenance price of the fan, but also consult the price of new equipment with the same parameters for comparison, considering whether it is cost-effective to purchase new equipment or maintain it.

4. Find the manufacturer, not the dealer

The dealer cannot repair the roots blower, because the dealer does not have processing equipment, so it is impossible to repair the roots blower. To repair the roots blower, you need to find the nearest manufacturer. The farther the distance is, the more troublesome the repair is, and the higher the price may be. Jingong Blower Maintenance Center provides external services, which can repair all major brands of Roots Blowers. The VIP of other factories is Jingong VIP.

5. Precautions

Generally, roots blowers are used, one for use and one for standby or one for use and multiple for standby. They are installed during installation. When one fan fails, the standby fan can be started, and the construction period will not be affected. If there is only one, it will be troublesome if there is a fault.
