Is compressed in compression chamber, the refrigerant after compressing flows into high pressure chest 2014 by gas vent 209, afterwards by with high pressure chest
The exhaust outlet 2012 of 2014 connections discharges compressor.
Eccentric crankshaft 19 drives oil pump 26 to be turned round compared with pump oil cylinder 25 by oil pump shaft 27, makes to be stored in compressor
The lubricating oil of the oil sump 31 of 309 bottom of low pressure chamber is inhaled into oil pumping chamber by the fuel feed hole 2801 with strainer and oil-sucking hole 2501
2502 and pass through outage 2601 and discharge.
The lubricating oil discharged from outage 2601 is divided into two parts：The groove that wherein sub-fraction lubricating oil passes through oil pump
2603 flow into lower bearing apertures, it can be achieved that good profit between oil pump shaft 27 and oil pump 26, between eccentric crankshaft 19 and lower bearing 18
It is sliding；Another major part lubricating oil passes through the through hole 2701 of oil pump shaft and the axial oil-through-hole 1902 of eccentric crankshaft 19 and inflow second
Oil pipe 1903.
The lubricating oil for flowing into the second oil pipe 1903 is divided into as two parts：A portion lubricating oil passes through radial direction oil hole 1904
The first oil groove 19051 of eccentric crankshaft outer surface is flowed into, the pair that rubs between eccentric crankshaft 19 and upper bearing (metal) 17 is lubricated；
Another part lubricating oil flows into the second oil groove 19052 of eccentric crankshaft outer surface by leading to oil pocket 19053, to 19 He of eccentric crankshaft
The pair that rubs between Moving plate bearing 16 is lubricated.
Since the rotating speed of compressor is higher and drives the synchronous operating of oil pump 26, has more lubricating oil and arrived by rapid pump
Oil groove 19051 and 19052, and pass through the counterbore 1103 that oil groove 19051 and 19052 flows into upper bracket 11, therefore almost moment is just
It has lubricating oil and accumulates in the intermediate oil sump 1103A of formation in counterbore 1103.When fuel head is sufficiently high, lubricating oil passes through upper
The keyway 1102 of stent 11 flows into cavity 1101 and intermediate oil sump 1101B is formed in cavity 1101, therefore lubricating oil can fill
Sub-dip arrives and the keyway 1102 to the key 2001 of anti-rotation mechanism and stent 11, key 2002 and movable orbiting scroll 15 keyway 1503 it
Between friction pair be lubricated.
And lubricating oil can be dipped into the one side of the fixed scroll 2 backwards of movable orbiting scroll 15 by the through hole 1401 of wear-resistant gasket 14,
With running at high speed for movable orbiting scroll 15, the lubricating oil for being dipped into its back side can be applied to wear-resistant gasket 14 and movable orbiting scroll by movable orbiting scroll 15
On supporting surface between 15, the lubrication between wear-resistant gasket 14 and movable orbiting scroll 15 is realized.Due to movable orbiting scroll 15 and wear-resistant gasket 14
Matching relationship meet R1 ＞ L1+r1 so that the through hole 1401 of wear-resistant gasket 14 is always by movable orbiting scroll 15 backwards to fixed scroll 2
End face is covered, therefore the lubrication backwards to the one side of fixed scroll 2 of movable orbiting scroll 15 is dipped by the through hole 1401 of wear-resistant gasket 14
Oil is always by the scroll wrap 201 and movable orbiting scroll that are covered backwards to the end face of fixed scroll 2 without flowing into fixed scroll 2 of movable orbiting scroll 15
The compression chamber that 15 scroll wrap 1501 cooperatively forms.
And upper oil blocking cover 22, lower oil blocking cover 23, upper bracket 11, motor stator 12, lower carriage 13 complement each other to form compared with
For closed space 34 and rotor 20 is wrapped in space 34, lubricating oil is isolated within space 34 substantially, it can base
Originally high-speed rotating rotor 20 or bent axle 19 is avoided to stir lubricating oil and lubricating oil is got rid of to the free air space for flying to refrigerant
In.
In addition, the lubricating oil accumulated in cavity 1101 flows to the endface of motor stator 12 by oil return pipe 32, and pass through
Gap between motor stator 12 and housing 3 returns to the oil sump 31 of 309 bottom of compressor low pressure chamber, is achieved in lubricating oil and is pressing
Recycling inside contracting machine.
Due to refrigerant from compressor air suction mouth 2010 is entered up to the scroll wrap 201 and movable orbiting scroll for flowing into fixed scroll
The free air space that the compression chamber that scroll wrap 1501 cooperatively forms is passed through all is distributed in the top of compressor low pressure chamber 309, and moistens
The oil sump 31 of lubricating oil is located at the bottom of low pressure chamber 309, and above-mentioned lubricating oil is from the fuel feed hole 2801 with strainer until logical
The gap crossed between motor stator 12 and housing 3 return to oil sump 31 compressor interior oil cycle overall process can realize lubricating oil with
Refrigerant circulation is substantially isolated, therefore is significantly reduced lubricating oil as refrigerant circulates and be discharged the probability of compressor.
To sum up, the lubricating system of this kind of screw compressor can realize nearly all friction to compressor internal drive mechanism
Secondary good lubrication, and can avoid lubricating oil as refrigerant circulates substantially and discharge compressor, compressor can be greatly reduced
Oil drain quantity.
Compared with prior art, the utility model is by setting the lead to the hole site lubricating oil of movable orbiting scroll, wear-resistant gasket can
To be lubricated by the through hole of wear-resistant gasket to the friction pair between movable orbiting scroll and wear-resistant gasket, movable orbiting scroll and wear-resistant pad are reduced
Mechanical failure between piece improves compressor reliability.
The illustrative embodiments of the utility model are particularly shown and described above.It should be understood that the utility model
Be not limited to disclosed embodiment, on the contrary, the utility model intention cover it is various comprising within the scope of the appended claims
Modification and equivalent replacement.
