Description
Technical field
The present invention discloses the technical field for being related to general machinery equipment design more particularly to a kind of water lubrication sliding-vane air
Compressor.
Background technique
A kind of universal machine of the sliding-vane air compressor as compressed air energy for converting electrical energy into certain pressure,
It is widely used in each industrial field, for control instrument, control valve, driving pneumatic tool, driving cylinder, blows
Sweep etc., since sliding-vane air compressor has many advantages, such as that structure is simple, operational efficiency is high, energy-saving effect is good, answered extensively
With.
Currently, sliding-vane air compressor refers to that oil-spraying sliding-vane air compressor, compressor are to rely at runtime
One systems such as sealing, compressed air cooling, bearing lubrication, the cooling for spraying into a large amount of lubricating oil into compression chamber to realize compression chamber
Column effect.It is preferred that using lubricating oil in existing oil-spraying sliding-vane air compressor, therefore have the disadvantage that
1, oil-containing in the air of compressor discharge.Because being injected compressor, compressed air is really oil gas
Mixture, then compressed air is discharged after isolating the oil in mixture by a series of gas oil separation structure and device, but press
Impossible 100% removal of oil in contracting air is clean, so outlet certainty oil-containing, in this way for needing oil content in compressed air
Be zero user for, be not just available.And with the increase of use time, the loss of Oil-gas Separation component, oil product
Oil content increases significantly in the rotten compressed air that can all lead to discharge, seriously affects the use of user, even result in user without
Method uses.
2, the running temperature of compressor is very high.Due to compressor be the lubricating oil by spraying into carry out it is cooling, lubricate and
Sealing, it is therefore necessary to guarantee that the use of lubricating oil is reliable, and effective minimum operating temperature of lubricating oil is at 75 DEG C or more, because
This, compressor needs to work under hot conditions of the temperature greater than 75 DEG C, however high temperature, it is intended that safety coefficient is low, height consumes
Can, host operational efficiency is low, and the service life of part is short, especially some sealing elements, and the service life run at high temperature is very short.
3, the maintenance expense of compressor is very high.Injected compressor major maintenance under the premise of no Parts Breakdown is protected
Have in supporting: replacement air filter core, oily filter core, oil core, lubricating oil, bearing, everywhere sealing ring.Renewal cost necessary in this way is just
It is very high, a 10m3/ min compressor 1 year the expense for maintenance will be up to nearly 10000 yuan, and (wherein lubricating oil will account for
To the expense of half), if occur again other failures that be used for expense for repairing and maintaining will be higher.
4, seriously polluted in compressor use.Injected compressor is after a period of use at each sealing, at jointing because
For machine vibration, the reasons such as seal fails more or less can all have oil seepage phenomenon, and the oil oozed out in this way and dust are mixed
It closes, so that entire machine is very dirty, it is in addition the leakage for unavoidably having lubricating oil when maintenance or maintenance, stream is being pressed
It is oil everywhere around contracting machine, it is extremely difficult to it removes, pollution environment (so it is forever all greasy around compressor in the impression of people,
Meet the taste of machine oil in air), because of oil-containing in the compressed air of discharge, this part oil and meeting contaminated equipment, the sky of surrounding
Gas.
5, injected compressor needs to configure complicated equipment for after-treatment.Because of outlet oil-containing and temperature height, it is necessary to configure
The equipment of a set of post-processing, wherein filter at different levels was used to the impurity in air filtering, oil, drying machine is used to reduce delivery temperature
Reach requirement.For configuring the air filter of more accuracy classes with the gas requirement higher user of quality.As long as
Pressure reduction will be generated with filter, pressure reduction means that compressor need to get to higher pressure and just be able to satisfy with gas need
It wants.Namely energy consumption can obviously increase, and virtually increase user and largely purchase machine cost and use cost.
Therefore, a kind of novel sliding-vane compressor how is researched and developed, to solve existing for existing oil spout sliding-vane compressor
Problem becomes people's urgent problem to be solved.
