Description
Technical field
The present invention relates to a kind of water spray double-screw compressor more particularly to a kind of water spray lubrications and cooling twin-screw air
Compressor belongs to mechanical equipment technical field.
Background technology
Helical-lobe compressor can be divided into single screw compressor and double-screw compressor, earliest by German H.Krigar in
It proposes within 1878, until Sweden Royal Institute of Technology A.Lysholm in 1934 just establishes this technology, and beginning is industrially answered
With obtaining rapid development.
Contact situation according to medium in compression chamber with lubricating oil, double-screw compressor include oil-free double-screw compressor and
There is oily double-screw compressor.
Dry type oil-free double-screw compressor compression chamber does not spray into the coolants such as lubricating oil or water, and yin-yang rotor gap is by synchronizing
Gear controls, it is ensured that yin-yang rotor does not contact during the motion, and power is transmitted to female rotor by male rotor by synchronizing this wheel.This
When, yin, yang rotor is inhaled, exhaust end uses thin oil lubricant bearing to carry out radial and axial positioning to rotor, uses oil lubrication pair
Bearing is lubricated and cools down, to ensure the high rotating speed of rotor；Yin, yang rotor is inhaled, exhaust end uses labyrinth seal or machinery
Sealing or（Labyrinth+machinery）Combination sealing（Compression chamber end is leaned in labyrinth seal）Compression chamber and bearing bore is isolated, to ensure lubricating oil
Do not enter in compression chamber, it is ensured that the pure oil-free of compressed gas；Synchromesh gear and speed increasing gear（Inlet end, input shaft）Using glossy
Cunning is lubricated and cools down.This compressor arrangement is simple, the substantially pure oil-free of compressed gas of generation.But it is lacked there is also following
Point：a）Yin, yang rotor inhales, the sealing structure of exhaust end, is unable to ensure lubricating oil and does not enter compression chamber, in case of mechanical seal
When failure, labyrinth seal mismachining tolerance or big service wear；Meanwhile the installation of mechanical seal is to installing the skill set requirements of skilled worker very
Height, mechanical seal failure are largely caused by installing；It is b) directly cooling because being carried out to compressed air without any medium,
Dry type oilless (oil free) compressor one stage of compression ratio cannot be too high, and rated discharge pressure 0.7MPa must just use two stages of compression, cause to lead
Machine mechanism becomes complicated；C) compression cavity shell must be cooled down using water, and yin, yang rotor is preferably passed through lubricating oil at center
It is cooled down so that compressor housing and main machine structure tend to complicate.
Water jet oil-free double-screw compressor compression chamber sprays into profit of the pure water as yin, yang rotor and water lubriucated bearing etc.
Lubrication prescription, meanwhile, pure water also absorbs the heat of compression generated in gas compression processes as compressed gas coolant, also, absorbs
The noise generated in gas compression processes.It is used because the pure water that such oil-free double-screw compressor sprays into can be used as lubricant,
Therefore, synchromesh gear can not be set between yin, yang rotor, at this moment, compressor host structure is the simplest.The disadvantage is that yin, yang rotor
Inhale, exhaust end honours rotor using water lubrication shaft and carries out radial and axial positioning, bearing is lubricated using pure water and
Cooling, because of the limitation of water lubriucated bearing, rotor is unable to reach the high rotating speed of best performance.In addition, because using axial water lubrication
Bearing is with balancing axial thrust, and axially position precision is not high, and compressor efficiency is declined.
