Description
Technical field
The present invention relates to rotary compressor, refer in particular to a kind of exhaust pipe oil cap and installation method thereof of rotary compressor.
Background technique
Along with improving constantly of people's living standard, the performance requirement of people to air-conditioning system is also more and more higher, and energy-conserving and environment-protective become the main flow of air-conditioning products gradually.One of most important factor affecting Performance for Air Conditioning Systems is the performance of compressor, due to the development comparative maturity of the rotary compressor of prior art, increasing substantially its efficiency has not been easy thing, therefore, need the improvement of paying attention to detail, wherein, reducing the exhaust oil content of rotary compressor, is exactly one of means of more effectively raising compressor matching performance.
Prior art reduces the exhaust oil content of rotary compressor (as shown in Figure 1 mainly through mounting block oiled-plate method on the rotor of rotary compressor, wherein, direction shown in arrow is the flow direction of refrigerant gas), design due to oil baffle is compressed the restriction of machine structure, its structural design and assembling all have certain narrow limitation, and thus its reduction compressor air-discharging oil content neither be very good.Such as: profile is that the oil baffle of slab design is very little to the disturbance of air-flow, gas and oil inferior separating effect; Flat board adds the design of vertical vane, the good separating effect of gas and oil, but the disturbance of air-flow increases simultaneously, and drag losses increases.In addition, because oil baffle is arranged on the upper end of rotating compressor rotor, such design makes air-flow first carry out gas and oil separation through air gap and then via oil baffle, so only some gas direct collision oil baffle, and gas and oil separating effect is poor.
Summary of the invention
The invention provides a kind of exhaust pipe oil cap of rotary compressor, it is installed on the end of outlet pipe, and not only gas and oil separating effect is good, and structure is simple, convenient processing and manufacture, and assembly process is simple, is not subject to the impact of rotary compressor structure and assembly technology.
The present invention is achieved in that
A kind of exhaust pipe oil cap of rotary compressor, it is semi-enclosed column structure, its include multiple oil drainage hole, this exhaust pipe oil cap local, upper end to the scaffold extended to form inside it and form mounting hole in the middle part of scaffold, this oil drainage hole is located at bottom this exhaust pipe oil cap, and this mounting hole coordinates with this outlet pipe the bottom this exhaust pipe oil cap being installed on this outlet pipe.Refrigerant gas is discharged from upper baffler, first flows through machine air gap, then encounters upper cover from lower to upper, flow to exhaust pipe oil cap downwards again, refrigerant gas upwards flows out outlet pipe afterwards, and oil droplet is then separated with refrigerant gas by the effect of gravity, discharges finally by oil drainage hole.
Preferably, the shape of this scaffold is " ten " shape, " one " shape, or " people " shape.
In order to ensure the installation fastness of this exhaust pipe oil cap and outlet pipe, this mounting hole is located at the middle part of this scaffold.
Preferably, mounting hole and the outlet pipe of this exhaust pipe oil cap are fixed by the mode of the mode of welding or interference fit.
Preferably, its cross section is circle, ellipse, rectangle, triangle or irregular shape.
The present invention also provides a kind of installation method of exhaust pipe oil cap of the rotary compressor as described in above any one, and it includes:
(1) outlet pipe, wiring terminal are individually fixed in cover;
(2) exhaust pipe oil cap is fixed on the lower end of this outlet pipe, makes the open-mouth end of this exhaust pipe oil cap towards outlet pipe.
(3) mounting hole of this exhaust pipe oil cap is fixed with the mode that outlet pipe passes through mode or the interference fit of welding.
Wherein, in step (1), the means of fixation of this outlet pipe is induction welding mode, and the means of fixation of this wiring terminal is resistance welding mode.
The present invention, relative to prior art, has following beneficial effect:
The exhaust pipe oil cap of rotary compressor of the present invention and installation method thereof, it effectively improves the efficiency that in the air-flow of rotary compressor, refrigerator oil is separated, and reduces the oil content of air-conditioning system, thus Energy Efficiency Ratio when improve rotary compressor coupling.

Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in detail:
As shown in Figures 2 and 3.The exhaust pipe oil cap 1 of rotary compressor of the present invention, it is the column structure of open at one end, includes scaffold 2, mounting hole 4 and 2 oil drainage holes 3.Wherein, this scaffold 2 by the local, upper end of this exhaust pipe oil cap 1 to extending to form inside it; This mounting hole 4 is located at the middle part of this scaffold 2, this mounting hole 4 is socketed with outlet pipe 5 bottom this exhaust pipe oil cap 1 being installed on this outlet pipe 5, in order to this mounting hole 4 can be made can to reach interference fit with this outlet pipe 5, preferably the internal diameter of this mounting hole 4 is slightly larger than the external diameter of this outlet pipe 5; This oil drainage hole 3 is located at the bottom of this exhaust pipe oil cap 1, makes after oil droplet is separated under gravity, to be discharged by this oil drainage hole 3.
In the present invention, the shape of this scaffold 2 can be " ten " shape, " one " shape, or " people " shape, and the present invention is preferably stable, firmly " ten " shape.The cross section of this exhaust pipe oil cap 1 is circle, ellipse, rectangle, triangle or irregular shape.
As shown in Figure 5, wherein, direction shown in arrow is the flow direction of refrigerant gas.The rotary compressor of this exhaust pipe oil cap 1 is installed operationally, after refrigerant gas is discharged from baffler, first through electric rotating machine gap, after meeting the blocking of this upper cover 6 or this wiring terminal 7 from bottom to top, enter this exhaust pipe oil cap 1 from the upper base of this exhaust pipe oil cap 1, afterwards, refrigerant gas is upwards discharged by outlet pipe 5 again, and is blended in the oil droplet in refrigerant gas, then because the effect of gravity is separated with refrigerant gas, finally, discharge through this oil drainage hole 3.
