Noise reduction of Roots blower - method of reducing noise during operation of three blade roots blower

Solution to oil leakage of three blade roots blower:

1. The seal is worn, causing oil leakage at the shaft end, and the equipment seal needs to be replaced.

2. The pressure value of three blade roots blower is higher than the specified value, and the equipment pressure shall be adjusted to the normal level.

3. The air vent of the three blade roots blower is blocked, causing oil leakage into the casing. The air vent needs to be dredged, and the middle chamber is installed with a plug with an aperture.

4. The oil level is high, and the oil drain leaks, so the oil level needs to be lowered.

Reasons for noise of three blade roots blower:

1. The installation position of the fan is incorrect.

2. The starting pressure of roots blower is too high, causing overheating and damage to roots blower.

3. In the production process, large abrasive particles will enter the Roots blower and cause wear of the machine.

4. Mechanical failure: poor assembly, guide gear and rotor position not within the rotor, gear damage due to overload or insufficient lubrication, bearing wear.

The reason is that the accuracy of roots blower may be reduced or seriously polluted, which may cause abnormal noise during the operation of roots blower.

After abnormal noise occurs during normal operation of Roots blower, it is necessary to immediately check whether the starting pressure of the fan reaches the specified value, and check the input current of the fan motor through the ammeter to check whether the input current of the fan motor is high or low.

Methods to reduce the noise of three blade roots blower during operation:

Installation of silencers, installation of sound insulation covers or transformation of fan rooms or pipe wrapping can effectively reduce noise interference and achieve noise control. These are general noise control methods that have been used in production at present, which are relatively easy to achieve and have achieved good results.

The noise control method is to try to avoid and reduce the noise radiation generated by the noise source, that is, to reduce the impulse force. Improving the aerodynamic design of roots blower and improving the installation and operation mode of three blade roots blower are the fundamental ways to achieve noise reduction of three blade roots blower.

Measures to solve the high temperature of three blade roots blower:

1. Keep ventilation and circulate the internal and external air reasonably and smoothly to make the air work better.

2. If the fan is installed indoors, if conditions permit, we can install cooling equipment, such as air conditioner, fan, etc. If the temperature of the motor continues to rise, the service life will be reduced.

3. Generally, fans are equipped with sound insulation equipment. In summer, we need to open the sound insulation cover. If the acoustic enclosure is not opened, a confined space will be formed inside the equipment, which will lead to higher suction temperature and higher outlet temperature.

4. Clean the machine in time. After the machine has operated for a period of time, we need to clean the equipment. The reason for high temperature may be that the filter and muffler of the fan are blocked, which leads to temperature rise. At this time, we need to clean the machine to remove the dust inside.

5. Reduce pipeline bends. The shorter the pipeline, the smaller the pressure it will bear and the smaller the pipeline loss will be.
