Is there a lot of microorganisms in the water lubricated screw air compressor?

Compressed air is ubiquitous in modern industry. Electronics, medicine, food, chemical and many other fields have high requirements for the quality of compressed air, requiring pure oil-free and dust-free compressed air. Water-jet screw oil-free air compressor is an emerging technology. It has attracted people's attention with many characteristics. The role of water in the water jet screw is cooling, sealing, and lubrication. Compared with the dry oil-free screw compressor, it has low compression temperature, small internal leakage, and high compression efficiency. Due to the action of water, the operation noise of the water spray screw is very low. If the water lubricated bearings are used again, the quality of oil-free compressed air can be guaranteed.

But it is also because of the water, food, medical users will worry about whether there will be microorganisms in the compressed air. So the water screw has such a risk?

Before answering this question, we need to understand the living conditions of microorganisms. The survival and reproduction of microorganisms requires several conditions: nutrition, temperature, pH, oxygen content, moisture, radiation, etc. Two conditions of temperature and moisture are involved in the compressor. Then look at the two conditions of the compressor is suitable for the growth and reproduction of microorganisms.

Temperature: Environmental microorganisms can be divided into three categories: low-temperature microorganisms, medium-temperature microorganisms and high-temperature microorganisms according to their growth temperature range. Their survival temperatures are -12~30°C,10~45°C and 25~70°C, respectively. High-temperature microorganisms are suitable for growing at temperatures above 45-50°C, and their distribution in nature is limited to certain areas, such as hot springs, sunny soil surface, compost, fermented feed and other decaying organic matter, such as compost. The temperature can reach 60-70°C. Pasteurization is to use 62~65 degrees or 75-90 degrees can kill 99% of the microorganisms in food.

The water-jet compressor evaluated the risk of microbial survival by simulation tests. Although there is water in the air compressor and the temperature is about 60°C, the microorganisms will die in the running compressor when they are under pressure due to the compressor conditions (temperature, pressure). It can be seen from the air produced by the compressor that even under the condition of serious water pollution, no microorganisms remain in the discharged air.
