Purchasing oil-free air compressor needs attention

Buy oil-free air compressor should pay attention to the point:

consider the safety of air compressor operation when choosing oil-free air compressor. Air compressor is a kind of machine with pressure work, accompanied by temperature rise and pressure, the safety of its operation should be put in the first place. The state implements a standardized "two-certificate" system for the production of air compressors, namely, the air compressor production license and the pressure vessel production license (gas tank).

Therefore, in the purchase of air compressor products, it is necessary to strictly review the "two certificates". Usually, the product system of the certified manufacturer is perfect, and there will be no major quality problems. Even if there are some problems, the manufacturer will be responsible for the three guarantees.

What about the abnormal vibration of air compressor: the recent price of air compressor in pharmaceutical industry.

When the air compressor is working, it is found that the vibration is not very normal, so it is necessary to consider whether there is something wrong with the installation. Based on experience, we judge what causes may be caused.

1. The anchor bolts of the air compressor unit are not fastened or the nuts are loose. Check whether the anchor screws are loose and tighten the anchor bolts.

2. When installing, the shim is placed improperly, or the number of shim layers is large, and the total thickness is too large, resulting in poor contact between the air compressor and the ground, poor rigidity, and large vibration.

3. Check the coupling to see if there are knock marks, whether the coupling assembly is biased, and whether the coupling transmission core is worn or damaged. Recalibrate the balance and replace the coupling and drive core.

4. Change the structure of the air compressor unit and related process pipelines, and change the hard pipe connection of the key parts to the corrugated pipe connection and the stainless steel hose connection to eliminate the resonance point.
