Reference:
1 is vacuum generator, and 2 is check valve, and 3 is oil pipe, and 4 is leakage of oil chamber, and 5 is breathing helmet, and 11 is compressed air air inlet
Mouthful, 12 are inhaled into mouth for leakage of oil, and 13 is gas mixture outlet.
Detailed description of the invention
With embodiment, this utility model is elaborated below in conjunction with the accompanying drawings.
Referring to Fig. 1 and Fig. 2, this utility model provides a kind of external oil sealing leaked oil recovering device, and it is mainly sent out by vacuum
Raw device 1, check valve 2, oil pipe 3, leakage of oil chamber 4 and breathing helmet 5 form, and they are linked together by pipe joint, pipeline, are placed in
The outside of helical lobe compressor host, becomes a kind of external oil sealing leaked oil recovering device, convenient installation.
Vacuum generator 1 is provided with compressed air inlet port 11, leakage of oil is inhaled into mouth 12 and gas mixture outlet 13,
Wherein leakage of oil is inhaled into mouth 12 and connects leakage of oil chamber 4 by oil pipe 3, and leakage of oil chamber 4 import connects breathing helmet 5.Check valve 2 is arranged on leakage
Oil is inhaled on the oil pipe 3 between mouth 12 and leakage of oil chamber 4.
Vacuum generator 1 is provided with nozzle at compressed air inlet port 11, and nozzle sprays into compressed air, make leakage of oil chamber 4 and
Its pipeline is formed vacuum and promotes check valve 2 to open, thus the lubricating oil that will leak out sucks compressor air suction chamber to reclaim leakage
Oil.The nozzle diameter of vacuum generator 1 is 0.5mm.Fig. 2 showing, compressed air passes through vacuum generator 1, can be in leakage of oil
Chamber 4 and pipeline thereof are formed vacuum, promotes check valve 2 to open, thus the lubricating oil that will leak out sucks compressor air suction chamber.
A ball valve can be set up on compressed-air line outside vacuum generator 1 compressed air inlet port 11, work as oil
When envelope normally works, close ball valve, compressed air can be saved；During oil sealing generation leakage of oil, ball valve is opened, and device is started working.
The work process of external oil sealing leaked oil recovering device of the present utility model is as follows:
During compressor operating, compressed air can be produced, when compressed air is by vacuum generator 1, owing to injecting type aspirates
Principle, cavity between check valve 2 and vacuum generator 1 can produce vacuum, promote check valve 2 to open.By compression
Persistently spraying into of air, can produce vacuum in oil pipe 3.
When oil sealing does not occur leakage, oil pipe 3 can persistently suck the air in leakage of oil chamber 4, and breathing helmet 5 can constantly
In leakage of oil chamber 4, supplement air, prevent vacuum in leakage of oil chamber too high.
When oil seal failure occurs leakage, the lubricating oil of leakage can enter bottom leakage of oil chamber 4, be drawn into pressure by oil pipe 3
The suction muffler of contracting machine, it is to avoid lubricating oil spills outside.
When the compressor is shut down, compressed air can constantly decay, and the pressure in suction muffler has one of short duration rose
Journey, in order to prevent the lubricating oil in compressor air suction chamber from pouring in down a chimney entrance leakage of oil chamber 4, therefore arranges check valve 2.When lubricating oil has down
During filling trend, check valve 2 can be because front and back pressure reduction reduces, and spool is closed under spring force, it is to avoid pouring in down a chimney of lubricating oil.
Vacuum generator 1 of the present utility model according to the size of leakage of oil amount, can select the vacuum generator of different size,
Generally, when helical-lobe compressor, the vacuum generator of minimum gauge can be selected, the nozzle diameter of vacuum generator
Only having 0.5mm, the air supply of consumption is small, and energy consumption is low.
Compressed air in this utility model typically after screw compression machine oil divides core, before minimum pressure valve introduce,
Persistently supply so that guarantee is compressed-air actuated, and avoid in compressed air containing too much lubricating oil.
External oil sealing leaked oil recovering device of the present utility model can be used for other to be needed to carry out setting of oil sealing leakproof
Standby, however it is necessary that and be additionally provided compressed air and gas mixture processing means.
Apply external oil sealing leaked oil recovering device of the present utility model, oil pipe access point and gas mixture in leakage of oil chamber
Pick out a little between difference in height, the most preferably greater than 2m, in order to avoid device effect is affected.
External oil sealing leaked oil recovering device of the present utility model in use, when user can accept a small amount of leakage of oil and
Personnel to equipment routing inspection frequent time, a valve can be increased on compressed-air actuated pipeline, when do not occur leakage time, close
Valve, saves compressed air, avoids energy consumption；After finding leakage of oil, it is then turned on valve, makes device start working.
External oil sealing leaked oil recovering device of the present utility model is in the mill, it is also possible to by the way of machining,
Vacuum generator and check valve are built in helical lobe compressor host housing, become built-in oil seal leaked oil recovering device, example
As by oilhole according to shown in Fig. 2 by the way of link together, make screw compressor system become cleaner and tidier, attractive in appearance.
Certainly, those skilled in the art in the art are it should be appreciated that above-described embodiment is intended merely to this reality is described
With novel, and it is not used as restriction of the present utility model, as long as in spirit of the present utility model, to above-mentioned reality
Execute the change of example, modification all will fall in the range of this utility model claim.
