What should be paid attention to when using Roots blower?

What should be paid attention to when using Roots blower? Roots blower is a rotary compressor that compresses and transports gas by using two blade rotors to make relative movement in the cylinder. The blower is simple in structure and easy to manufacture. It is widely used in aquaculture oxygenation, sewage treatment aeration, cement transmission, and more suitable for gas transmission and pressurization systems in low pressure occasions, and can also be used as a vacuum pump. What should be noticed about Roots blower? Let's have a look:

1. The maintenance and overhaul shall be carried out on schedule according to the specific use conditions, and a reasonable maintenance system shall be formulated and recorded. It is recommended to overhaul once a year, and replace bearings and relevant vulnerable parts.

2. Before disassembling the machine, measure and record the matching dimensions of roots blower, and mark the parts to ensure that the original matching requirements are maintained after assembly.

3. Regularly check the fastening condition of all parts of roots blower and whether the locating pin is loose, and check that there is no oil leakage, scaling, rust and peeling inside the machine body.

4. Pay attention to whether the lubrication and heat dissipation are normal, pay attention to the quality of lubricating oil, often listen to whether the blower runs noisily, pay attention to whether the unit operates under the condition that does not meet the requirements, and pay attention to adding grease regularly.

5. Overload of roots blower is sometimes not displayed immediately, so pay attention to the increasing trend of inlet and exhaust pressure, bearing temperature and motor current to judge whether the machine operates normally.

6. For new machines or overhauled three blade roots blowers, the oil tank should be cleaned and put into operation according to the operating procedures. It is recommended to replace all lubricating oil after 8 hours of operation.

The operation and service life of roots blower are affected by many human factors. If maintenance and attention are paid at ordinary times, the service life and failure rate can be improved.
