Zhangjiagang briefly discusses the auxiliary devices of air compressors
< 1. Air compressor lubrication device
. .< Lubrication device
. We all know that the internal mechanism of an air compressor is connected by large and small piston rings, cylinder walls, packing, piston rods, crankshafts, bearings, cross slides, etc. When they are running, friction generates a lot of heat. In order to make them To better serve the air compressor, we must inject lubricating oil to reduce friction and power consumption, take away heat, thereby lowering the temperature and improving their working efficiency. Of course, in addition to this, the lubricating oil also ensures the necessary operating clearance of the sliding parts, preventing the sliding parts from overheating or seizing. When it is running, the lubricating oil fills the friction surface, enhances the sealing, and also reduces the wear of the sliding parts. Extended part life.
. < Therefore, lubrication is one of the important issues in compressors. It is related to the performance indicators, life and reliability of the compressor, and ensures safety.
< 2. Air compressor cooling device
. .< Cooling device
. Speaking of which, please don’t think: isn’t lubricating oil able to cool the oil temperature to lower it? Why is there a cooling device? Yes. Lubricating oil mainly lubricates, improves operation, and prevents the temperature from being too high, but it cannot fundamentally solve the problem of refrigeration, because the compressor is not a separate part that works alone. They complement each other, so it must be fundamentally refrigerated. Moreover, even if the general small air compressor has refrigeration in its own link, it is still unsatisfactory. Therefore, air compressors generally use water cooling.
' ' - . - - The water cooling system of an air compressor generally consists of a water source (
cooling pool, water well)
and a water supply device (
water pump, pipeline, valve)
br/>It is composed of water equipment (
cylinder water jacket, cooler)
and pipelines. If the cooling water is recycled, there should also be a cooling water tower or pool. The cooling water circulation system should be equipped with pressure gauges, thermometers, automatic water cutoff control protection and signaling devices, as well as flow meters, water level gauges, etc.
< 3. Air compressor filter device
. .< Filter device
< The principle of air compressor filtration is that before air enters the cylinder, it must pass through the air filter to eliminate dust and other impurities. .
The air filter is mainly composed of a housing and a filter core. Types of filtering devices include: paper filters (
for air compressors with a displacement of

or less)
, metal air filters (

and oil bath air filters (
