What is the content of daily patrol maintenance of Roots blower_ Roots blower

After the roots blower is installed, the patrol inspection is very important. Daily inspection of the blower can effectively prevent the occurrence of faults. The key work of patrol inspection is as follows:

1. Fan temperature

The temperature inspection parts of the fan include the casing, bearing, inlet and outlet and other temperatures. High temperature has a great impact on the fan. Therefore, daily patrol inspection is a necessary work. If our fan has cooling water pipes, check the temperature of the lower cooling water pipes. The temperature should not be too high.

2. Pressure gauge inspection

The pressure gauge of the fan is also the content that needs to be checked every day. The pressure gauge value of Roots blower should be consistent with the pressure on the nameplate, and the pressure on the nameplate must not be exceeded. This will cause overpressure of the fan, which will cause serious damage to the fan! The burning motor is second level.

3. Noise inspection

When Roots blower is running, there is usually wind noise. Listen to the fan noise, mainly to avoid mechanical friction sound. Mechanical friction sound may be caused by mechanical friction inside the fan and internal failure.

4. Vibration inspection

The abnormal vibration of the fan needs to be monitored. The fan can not reflect on the noise, but may be detected on the vibration. The abnormal vibration will also reflect the fault. Therefore, at the initial stage of procurement, we should prepare various detection equipment, deliver it to the responsible personnel, conduct regular inspection and make records.

5. Other maintenance work

In addition to regularly checking these contents every day, we also need to regularly maintain other components of the fan. If you do not have a description of the maintenance cycle, you can see the Maintenance Cycle of Roots Blower here

1. First, listen to whether the running sound of the equipment is normal, whether there is collision sound between the impeller and whether there is friction sound between the impeller and the housing; Whether the gear meshing sound is even; Check whether the drive belt is too loose and there is a beating sound. Listen to whether the bearing makes even noise.

2. The second is to check the vibration of the equipment, and check whether the vibration of the equipment increases, mainly the bearing and transmission, and whether the pipeline vibrates in other aspects.

3. Check the looseness, and see if the anchor bolts and other fasteners are loose.

4. Temperature inspection, mainly including bearing, housing, motor, etc.

5. Check the lubrication to see if the oil level of the gearbox is normal.

6. Check the unstable objects to see if the transmission shield interferes, and clean the unstable objects around the equipment that hinder the operation of the equipment.

7. Check other aspects to see whether the air inlet is blocked, whether the safety valve is reliable, whether the valves are reliable, whether the supports are cracked and other abnormal phenomena.

8. Check whether the motor current, fan flow pressure, etc. are normal.
