For contracting machine by after gas compression, compressed gas can carry amount of heat, and the compressed gas passes through in breather line and cooling water tank
Water at low temperature carries out heat exchange, carries out cooling processing, while dispersed heat is used for warm water, can be effectively by compressed air institute
The heat of carrying is reclaimed, and breather line, which is located at cooling water tank part, can be multiple pipeline compositions being set up in parallel or be spiral shell
The structures such as shape are revolved, increases the length in cooling water tank to increase contact area and heat exchanger time, improves heat exchanger effectiveness
And then improve heat recovery efficiency；Air cleaner is used for the inlet air filtration of fuel injection helical lobe compressor, improves compressed air cleannes；
Cooler is used for the final cooling processing to compressed air, and the compressed air temperature that reducing output temperature makes to obtain reduces；
Fuel injection helical lobe compressor, positioned at internal body to improve air compression ratio, the air of primary compression can be carried out just
Step cooling, to improve its compression efficiency, the cooling method is by the way of oil spout, that is to say, that by low-temperature lubrication oil spurts and with
The air of primary compression is mixed, and to reduce its temperature, while the compressed air for carrying lubricating oil also will be in compressor
The rotatable parts such as screw rod be lubricated, reduce its mechanical wear, improve its service life；Oil storage barrel is used to store lubricating oil,
Injection pump is used to that oil spurts will to be lubricated；The outlet of fuel injection helical lobe compressor is connected in oil storage barrel, and oil storage barrel upper end passes through pipeline
Breather line is connected, compressed air sprays from fuel injection helical lobe compressor, can carry a part of lubricating oil, compressed air is passed through oil storage
In bucket and this is passed through liquid level once, and the lubricating oil entrained by compressed air will lubricate oil wash in oil storage barrel, reduces compression
Lubricants capacity entrained by air, exhaust quality is improved, while compressed air can also be carried out once with the lubricating oil in oil storage barrel
Heat exchange, and the temperature of lubricating oil is increased, while lubricating oil pipeline is also by cooling water tank, can be incited somebody to action in cooling water tank
Heat absorption entrained by lubricating oil, improve waste heat recovery efficiency；Can be in lubricating oil in connecting filter on oil spout pipeline
Entrained debris is filtered, and prevents debris from blocking the oil spout cooling in injection tubing influence fuel injection helical lobe compressor；
At the same time it can also be used to monitor in the equipment such as setting oil pressure gauge, liquid level gauge in the equipment such as injection tubing, oil storage tank.
Cooler is one kind of heat transmission equipment, to cooling fluid, generally with water or air are cooling agent to remove heat.
