Structural representation during the positive displacement compressor twin-tub shape body that Fig. 2 provides for this utility model embodiment.
Detailed description of the invention
Core of the present utility model is to provide a kind of positive displacement compressor, to reduce the noise of positive displacement compressor.Another core of the present utility model is to provide a kind of refrigeration plant with above-mentioned positive displacement compressor.
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 2, the utility model discloses a kind of positive displacement compressor, including bent axle 11, upper flange 12, long spiro nail 13, upper cylinder 14, upper roller 15, upper slide plate 16, pump partition plate 17, lower cylinder 18, lower roller 19, lower slide plate 20, lower flange 21, permanent magnet 23, coil 24 and lower cover 25, and the position of correspondence and annexation are all as depicted in figs. 1 and 2. The core of the positive displacement compressor in the application is in that, also include installing hole and the connector 22 can locked with lower slide plate 20 and separate, this connector 22 can move axis direction along installing hole in installing hole, and wherein, this connector 22 is threadeded with installing hole. By by threaded to installing hole and connector 22, rotating connector 22 can be passed through and realizes the connector 22 movement in installing hole, thus realizing connection and the release of lower slide plate 20 and lower roller 19. When connector 22 separates with lower slide plate 20 so that lower slide plate 20 contacts with lower roller 19 and does followability motion with lower roller 20, and after compressor start, lower cylinder 18 equally carries out normally compressed with upper cylinder 14, forms the twin-tub of conventional duplex cylinder compressor; When connector 22 is locked with lower slide plate 20, lower slide plate 20 cannot do followability motion with lower roller 19, and lower cylinder 18 is revealed, and is not compressed, then compressor shows as the single cylinder operational mode of only upper cylinder 14 compression. Adopt threaded mode that the operation of connector 22 can be made accurate by the guiding of screw thread, it is to avoid the connector 22 collision with lower slide plate 20, thus reducing the noise of this positive displacement compressor.
In specific embodiment, above-mentioned connector 22 is defined to pin, is threaded by the periphery at pin, and corresponding setting on the inwall of installing hole realizes threadeding of pin and installing hole with the screw thread of the threaded engagement of pin. Direction for pin and the screw thread of installing hole is not specifically limited at this, as long as ensureing that both are threaded. Adopt threaded the pin pin of original matched in clearance and gap of installing hole compared with the gap that installing hole coordinates less, threaded making positive displacement compressor seal with screwed joint better effects if of pin and installing hole when twin-tub operational mode, gas leakage amount is less. When twin-tub runs, its energy consumption is equal to common twin-tub efficiency, thus improving compressor performance under twin-tub runs.
In further embodiment, this positive displacement compressor also includes being connected with connector 22, for driving connector 22 driving device of movement in installing hole. By using driving device can avoid manual rotation's connector, therefore, reduce the labor intensity of operator.
In preferred embodiment, driving device is set as drive motor, under the effect of drive motor, is combine in proper order and separate between pin with installing hole, action is accurate, it is to avoid pin and the collision of lower slide plate 20, reduces the noise of compressor.Additionally, use drive motor is compared, hydraulic motor can reduce check valve etc. and control the pipeline of liquid, therefore, cost-saved.
In one embodiment, driving device is arranged on the lower cover 25 of this positive displacement compressor, merely provide the concrete installation site of a kind of driving device herein, but the application is not limited to that position, as long as being capable of driving device to drive the movement of connector.
On the basis of technique scheme, installing hole disclosed herein includes the linkage section being positioned on lower slide plate 20 and the set section being positioned at the lower flange 21 contacted with lower slide plate 20, and linkage section connects with set section. In connector 22 moving process, when connector 22 moves to linkage section, connector 22 and lower slide plate 20 are locked; When connector 22 depart from linkage section be positioned at set section time, connector 22 separates with lower slide plate 20.
In order to optimize technique scheme further, the diameter of linkage section disclosed herein is less than the diameter of set section, and connector 22 has the clamping section that can coordinate with linkage section. By above-mentioned installing hole and connector 22 being disposed as the structure of variable cross-section further the movement of connector 22 to be led, and variable cross-section also can limit the moving displacement of connector 22, it is prevented that connector 22 and lower slide plate 20 clash into.
In addition, disclosed herein as well is a kind of refrigeration plant, including positive displacement compressor, owing to this positive displacement compressor is the positive displacement compressor disclosed in above-described embodiment, the refrigeration plant therefore with this positive displacement compressor also has above-mentioned all technique effects, and this is no longer going to repeat them.
In this specification, each embodiment adopts the mode gone forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually referring to.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this utility model.
