Embodiment
Illustrated in more detail with reference to Fig. 1~Fig. 2 technical schemes provided the present invention.
Referring to Fig. 1, the embodiment of the present invention provides a kind of oil groove system, including oil eliminator, oil groove 1, oil heater 2 and oil
Liquid mixing component.Oil groove 1 is located at the lower section of oil eliminator and for accepting the fluid that oil eliminator is separated, oil heater 2
For the fluid in heating oil tank 1.Fluid mixing component is used to stir the fluid in oil groove 1.
Fluid mixing component can include revolvable blade or axle, be rotated by external force driving blade or axle, to cause
The inner fluid of oil groove 1 is by uniform stirring.Or, fluid mixing component includes circulating pump 3, forces the inner fluid of oil groove 1 to circulate by pump
Flowing, to cause the inner fluid of oil groove 1 by uniform stirring.
After adopting the above technical scheme, the set location of oil heater 2 can be arbitrary, because circulating pump 3 can be to oil
Fluid in groove 1 plays stirring action, can also cause that the inner fluid temperature of oil groove 1 is equal in the case of only one of which oil heater 2
It is even, it is to avoid refrigerant is dissolved in lubricating oil, it is to avoid absorbing gas belt liquid during unit start, it is ensured that the reliability of unit operation.
Fluid mixing component includes circulating pump 3, and the entrance 31 of circulating pump 3 and outlet 32 are connected with oil groove 1.Circulating pump 3
It is arranged on outside oil groove 1, it is used to extract and then be emitted into the fluid at one in oil groove 1 out another place, and stirring oil is realized with this
The effect of the inner fluid of groove 1.
The arrow of the upstream and downstream of circulating pump 3 is illustrated in flow direction of the fluid under the effect of circulating pump 3, oil groove 1 in Fig. 1
Fluid comes from the refrigeration oil that oil eliminator is filtrated to get, and the arrow of the ullage of oil groove 1 illustrates oil eliminator and is filtrated to get
Oil drops under direction.
The oil groove system that above-mentioned technical proposal is provided, is that oil groove adds circulating pump, can cause oil groove by circulating pump
Interior fluid is in recurrent state, so can effectively stir fluid, even if only setting an oil heater also to cause in oil groove
The oil temperature of fluid is uniform.
The entrance 31 of circulating pump 3 is connected with position of the oil groove 1 away from oil heater 2, outlet 32 and the oil groove 1 of circulating pump 3
The position of neighbouring oil heater 2 is connected.So the low temperature fluid in oil groove 1 is extracted out and is emitted near oil heater 2, in order to
Oil heater 2 is heated.Which can quickly make it that oil temperature is uniform in oil groove 1.
Alternatively, circulating pump 3 include it is multiple, such as two or more, each circulating pump 3 works independently.Each circulation
The entrance 31 of pump 3 is spaced, outlet 32 is spaced.The circulation rate of multiple circulating pumps 3 faster, can more rapidly cause
Oil temperature in oil groove 1 is uniform.Pass through the forced circulation of refrigeration oil in oil groove 1, it is ensured that refrigeration oil is heated evenly in oil groove 1.
Avoid refrigerant of the refrigeration oil with dissolving for being supplied to bearing and rotor chamber, it is ensured that the reliability of unit operation.
Referring to Fig. 1, for the ease of the oil liquid temperature at low temperature in detection oil groove 1, oil groove system also includes being used to detect oil
First temperature-detecting device 4 of the inner fluid temperature of groove 1, the first temperature-detecting device 4 is away from oil heater 2.Apart from oil heater 2
More remote, oil temperature is lower;Closer to oil heater 2, oil temperature is higher.
Alternatively, oil groove system also includes the first controller, and the first controller is used to detect in the first temperature-detecting device 4
The oil liquid temperature value arrived starts fluid mixing component in fluid mixing component, the present embodiment when being less than setting value include circulating pump 3.
Setting value can be manually set in advance, less than the setting value, be illustrated in oil groove 1 away from the oil temperature at oil heater 2
It is too low, now need to start circulating pump 3 to stir the inner fluid of oil groove 1.
Referring to Fig. 1, alternatively, oil groove system also includes the second temperature detection dress for being used to detect the inner fluid temperature of oil groove 1
5 are put, the first temperature-detecting device 4 is adjacent to oil heater 2.Second temperature detection means 5 is used to detect the oil near oil heater 2
Temperature, it is necessary to stop oil heater 2 when oil temperature herein is too high, to avoid danger.
For ease of control the opening of oil heater 2, stop, oil groove system also includes second controller, second controller is used for
The oil liquid temperature value that second temperature detection means 5 is detected stops oil heater 2 when being higher than threshold value.Threshold value can think to set in advance
Fixed, when the oil liquid temperature value detected is higher than the threshold value, continuing heating, to be likely to result in oil liquid temperature too high, therefore need to stop oily heating
Device 2.
Referring to Fig. 1, the entrance 31 of circulating pump 3 is connected by the first pipeline 6 with position of the oil groove 1 away from oil heater 2, is followed
The outlet 32 of ring pump 3 is connected by the second pipeline 7 with oil groove 1 adjacent to the position of oil heater 2.
Further, the first pipeline 6 is provided with branch road 8, and branch road 8 is used to fluid being delivered to part to be lubricated.Branch road 8 will
Fluid is delivered to bearing rotor chamber, plays lubrication effect.
As shown in Figure 1:Refrigeration oil by power of suction draught head by the refrigeration oil in oil groove 1 along branch road 8 from oil groove 1
Flow in bearing and rotor chamber, bearing is lubricated, rotor chamber is cooled down and lubricated, it is ensured that screw compressor
Normal reliable is run.
Above-mentioned technical proposal, solves the problem of larger refrigeration oil oil groove 1 heats uneven.Can by oil circulating system
To ensure that the preheating of refrigeration oil between the refrigeration oil of the distal end of oil heater 2 and the near-end of oil heater 2 is uniform, it is to avoid distal end is freezed
Oil dissolving refrigerant, it is to avoid unit start air-breathing treats liquid, improves the reliability of unit operation.
Alternatively, the import of the first pipeline 6 is provided with filter element 9, will be delivered to first after the oil filtrating in oil groove 1
Pipeline 6.Filter element 9 may include screen pack, filter etc..
The technical scheme of embodiment illustrated in fig. 2 and the technical scheme of above-described embodiment have following difference, implement shown in Fig. 2
In example, branch road 8 is not provided with, the driving fluid of circulating pump 3 only does interior circulation.Described in other guide is seen above, no longer go to live in the household of one's in-laws on getting married herein
State.
Another embodiment of the present invention provides a kind of compressor assembly, including compressor and any technical scheme of the invention are carried
The oil groove system of confession, the oil-feed port of compressor is connected with the oil groove 1 of oil groove system.The uniform fluid of temperature is defeated in oil groove system
Compressor is delivered to, lubrication, clearance seal is played, cools down, takes away granule foreign, it is ensured that the effect of the reliability service of unit, due to
The oil liquid temperature of oil groove system supply compressor is uniform, the refrigerant that fluid can dissolve seldom, even without pressure can be prevented effectively from
There is absorbing gas belt liquid phenomenon in contracting machine.
