Connect.Axle sleeve 2 is installed on head axle 1, sealing ring 3 is provided between axle sleeve 2 and counter flange 15, can be prevented in compressor head
In oil leak to the housing 5 of compressor electric motor.But if sealing ring 3 fails, the lubricating oil in compressor head is still
It can leak in housing 5.
Therefore, as an improvement, as shown in figure 1, counter flange 15 is offered for collecting by compressing close to the side of housing 5
The groove 1501 for the lubricating oil that machine head leaks to housing 5, side of the counter flange 15 away from housing 5 offers arranges for lubricating oil
The oil-out 1502 gone out, oil-out 1502 connect with groove 1501.If sealing ring 3 fails, the lubricating oil in compressor head
Sealed circle 3 is leaked in groove 1501, then is discharged through oil-out 1502.The lubricating oil discharged through oil-out 1502 can pass through oil
Pump is recycled to Lubricating oil tank, and compressor head re-using can be also directly recycled to by vacuum generator 8.
As shown in figure 1, oil-out 1502 is connected with vacuum generator 8, vacuum generator 8 is provided with compressed air inlet
8011st, air-fuel mixture outlet 8012 and vacuum port 8013, compressed air inlet 8011 are connected with compressed air gas source, air-fuel mixture
Outlet 8012 is connected with the air inlet of compressor head, and vacuum port 8013 is connected with oil-out 1502.When high pressure air from
After compressed air inlet 8011 enters vacuum generator 8, negative pressure can be formed at vacuum port 8013 so that come out by oil-out 1502
Lubricating oil vacuum generator 8 and the high pressure air with being come in by compressed air inlet 8011 can be sucked by vacuum port 8013
Mix, be back to the air inlets of compressor head after air-fuel mixture by air-fuel mixture outlet 8012 together.Wherein, compressed air gas
Source can use the high pressure air come out by compressor assembly, such as the compressed air discharged by compressor cooler.
In order to prevent lubricating oil from flowing back, check valve 14 can be set between oil-out 1502 and vacuum port 8013, such as Fig. 1 institutes
Show, pipe joint 12 is provided with oil-out 1502, is connected between pipe joint 12 and check valve 14 by flexible pipe 13.
Referring to Fig. 2, it illustrates the concrete structure of vacuum generator in Fig. 18, the vacuum generator 8 includes body 801,
Compressed air inlet 8011, air-fuel mixture outlet 8012 and vacuum port 8013 are on body 801.
Specifically, formed with the chamber 802 mixed for compressed air and lubricating oil, chamber 802 and vacuum port in body 801
8013 connect, and are plugged with the first plug connector 803 and the second plug connector 804 in body 801, the first plug connector 803 offers first

Copper.
Referring to Fig. 2 and Fig. 1 is combined, the operation principle of the vacuum generator 8 is：High pressure air is from compressed air inlet
8011 enter in body 801, and are sprayed at a high speed through first through hole 8031, form jet, and volume is produced in chamber 802 and inhales flowing,
So that the air in chamber 802 is constantly sucked away, so that the pressure in chamber 802 is down to below atmospheric pressure, formed negative
Pressure, and then the lubricating oil for be come out by oil-out 1502 can be by the intake chamber 802 of vacuum port 8013 and empty with high pressure compressed
Gas mixes, and gas mixture sprays after through the second through hole 8041, and pressure raises with the reduction of flow velocity so that lubricating oil is with height
Pressure compressed air is back to the air inlet of compressor head by air-fuel mixture outlet 8012 together.
Compressor electric motor of the present utility model, by opening up groove 1501 on counter flange 15 and connecting with the groove 1501
Logical oil-out 1502 so that collected from the lubricating oil that compressor head leaks to housing 5 to the groove 1501 and by oil-out
1502 discharges；The lubricating oil discharged by oil-out 1502 can be recycled to compressor head re-using through vacuum generator 8, so as to
Ensure that compressor can also be run without interruption in the case where sealing ring 3 fails, can effectively reduce the number of maintenance, contract
In the short maintenance service cycle, reduce client's loss.
More than, schematic description only of the present utility model, it will be recognized by those skilled in the art that without departing from this practicality
On the basis of new operation principle, a variety of improvement can be made to the utility model, this belongs to protection of the present utility model
Scope.
