The oil-free air compressor for laboratory refers to the air compressor that is specially used in some universities, scientific research institutions and other laboratory environments. The machine is required to be precise, more reliable, environmentally friendly and quiet, and the compressed air is fresh and clean.
The oil-free air compressor used in the laboratory is generally a piston air compressor. Its working principle is: when the motor single-shaft drives the compressor crankshaft to rotate, through the transmission of the connecting rod, the piston with self-lubricating without adding any lubricant is easy to operate. During the reciprocating motion, the working volume formed by the inner wall of the cylinder, the cylinder head and the top surface of the piston will change periodically, so as to achieve the effect of compressing the gas.
Due to the particularity of the laboratory environment, especially the very high requirements for working noise, the following three technical standards must be met for the laboratory oil-free air compressor:
1. Low noise: The laboratory air compressor must be controlled within 60 decibels. In order to let everyone understand how much noise is 60 decibels, let's take an example: the sound of general household air conditioner compressors (about 55 decibels), the staff will not feel uncomfortable working in such an environment. Given that most laboratories require a quiet environment, an air compressor with a noise higher than 60 decibels is not suitable for use in a laboratory environment.
2. Air dryness and cleanliness: the application of oil-free lubrication technology, as well as the treatment of the inner wall of the compressor air tank and the spraying treatment technology inside the air storage tank, coupled with a good air filter and oil-water separator, to ensure that the output air is more clean. Clean and fresh. If a heatless regeneration dryer is installed, it can also ensure that the air is dry without water.
3. Exhaust pressure range: The industry standard stipulates that the exhaust pressure of the oil-free air compressor used in the laboratory must reach 7 Bar. That is to say, the exhaust pressure range must be between 0-7 Bar.
