Description
[technical field]
The utility model relates to technical field of refrigeration compressors, relates in particular to a kind of twin-stage rotary compressor.
[background technique]
At present during twin-stage (increasing enthalpy) compressor operating; Gas sucks from liquor separator, after first order compression, enters a cavity of pressing in being similar to; The middle interior gas of cavity of pressing is the suction end of second level compression; Through reaching secondary compression purpose after the compression of the second level, it is through on the casing wall of each part of the pump housing, opening, like Fig. 5 and shown in Figure 6 that its one-level is vented to the air-breathing middle pressure chamber passage of secondary; In press the chamber passage to cause conflict and the position is moved in needs adjustment with screw hole and other holes, it is extremely inconvenient to install and process.
[model utility content]
The utility model provides a kind of simple in structure, installation and processing technology convenient, and versatility is high, the twin-stage rotary compressor.
For reaching above purpose, adopt following technological scheme:
A kind of twin-stage rotary compressor; Comprise top-down last baffler, upper flange, go up roller, dividing plate, cover plate, lower roller, lower flange, lower flange cover plate along the crankshaft center line setting; Said upper and lower roller is installed on respectively in the upper and lower cylinder; Last roller and upper cylinder form second compression chamber, and lower roller and lower cylinder form first compression chamber; Dividing plate downside between said first compression chamber and second compression chamber is set up a cover plate, is communicated with through dividing plate and the cover plate for sealing that is sleeved on the bent axle between first compression chamber and second compression chamber, offers the pore that is communicated with first compression chamber on the said cover plate; Said dividing plate one side offer with cover plate on the arc gas guide groove that is communicated with of pore, on dividing plate, also be provided with the inlet hole that is communicated with the arc gas guide groove and second compression chamber.
Said dividing plate and cover plate are corresponding respectively offers screw hole, and said dividing plate is connected with cover plate dependence pump housing screw.
The beneficial effect of the utility model:
Offer the pore that is communicated with first compression chamber on the cover plate of the utility model; First compression chamber and second compression chamber adopt the double layer design of dividing plate and cover plate separation, be provided with on the side of dividing plate with cover plate on the arc gas guide groove that is communicated with of pore, also be provided with the inlet hole that is communicated with the arc gas guide groove and second compression chamber at dividing plate; Air-flow path through forming on cover plate and the dividing plate directly is communicated with first compression chamber with second compression chamber; The influence that the hole bit swiping of solution one dividing plate causes the screw arrangement inequality to bring makes dividing plate not receive the restriction of screw and other positions, hole, screw is evenly distributed is convenient to fastening cylinder; The air-flow path size that forms on cover plate and the dividing plate is unrestricted; Can make Channel Design not receive structural limitations greater than the one-level air displacement, can get into the secondary suction end directly and accurately; Simultaneously, it is fastening that pump housing screw is used in the combination of dividing plate and cover plate split passage, do not need extra fastenings.

[embodiment]
To combine accompanying drawing that the utility model is further specified below:
Extremely shown in Figure 4 like Fig. 1; A kind of twin-stage rotary compressor; Comprise sucking pipe 1, housing 2, drive motor, bent axle 5 and the last baffler 3 that is provided with along bent axle 5 axis, upper flange 4 from top to bottom, go up roller 6, dividing plate 8, cover plate 9, lower roller 10, lower flange 12 and lower flange cover plate 14; Air-flow path on the said lower flange 12 with increase enthalpy pipe 13 and be connected, last roller 6 forms second compression chamber 15 with upper cylinder 7, lower roller 10 forms first compression chamber 16 with lower cylinder 11.
Extremely shown in Figure 4 like Fig. 2; Dividing plate 8 downsides between said first compression chamber 16 and second compression chamber 15 are set up a cover plate 9; 9 sealings are communicated with cover plate through being sleeved on dividing plate 8 on the bent axle 5 between first compression chamber 16 and second compression chamber 15, offer the pore 90 that is communicated with first compression chamber 16 on the said cover plate 9; Said dividing plate 8 one sides offer with cover plate 9 on the arc gas guide groove 80 that is communicated with of pore 90; On dividing plate 8, also be provided with the inlet hole 81 that is communicated with the arc gas guide groove 80 and second compression chamber 15; Directly be communicated with second compression chamber 15 of upper cylinder 7 through the air-flow path that forms on cover plate 9 and the dividing plate 8 first compression chamber 16 lower cylinder 11; Simultaneously dividing plate 8 and cover plate 9 are corresponding respectively offers screw hole 83, makes dividing plate 8 rely on pump housing screws 84 to be fixedly connected with cover plate 9, the influence that the hole bit swiping of solution one dividing plate causes the screw arrangement inequality to bring; Make dividing plate 8 not receive the restriction of screw and other positions, hole, screw is evenly distributed is convenient to fastening cylinder.
During this compressor operating; The upper and lower roller (6,10) that drive motor drives bent axle 5 rotates in the upper and lower cylinder (7,11) rotates; Refrigerant is first compression chamber 16 in sucking pipe 1 gets into lower cylinder 11, and the compression back after increasing enthalpy pipe 13 and increasing enthalpy, gets into the air-flow path of formation on cover plate 9 and the dividing plate 8 through the pipeline of offering on the lower cylinder 11 in lower flange 12 passages; Directly get into second compression chamber 15 of upper cylinder 7 then; Having solved in the past one-level, to be vented to the air-breathing middle pressure chamber passage of secondary be through on the casing wall of each part of the pump housing, opening design, and the air-flow path size of formation is unrestricted, can be greater than the one-level air displacement; Make Channel Design not receive structural limitations, can get into the secondary suction end directly and accurately.
The above embodiment; It is the preferred embodiments of the utility model; Be not to limit the utility model practical range,, all should be included in the utility model patent claim so all equivalences of doing according to the described structure of the utility model claim, characteristic and principle change or modify.
