Abstract
The invention discloses refrigeration equipment and a variable-capacity compressor thereof. The variable-capacity compressor comprises a mounting hole and a connector capable of being locked with and separated from a lower slide piece, and the connector which is in threaded connection with the mounting hole can move in the mounting hole along the axis direction thereof. Since the mounting hole and the connector are in threaded connection, the connector can be rotated to move in the mounting hole, and connection and disconnection of the lower slide piece and a lower roller are realized. When the connector is separated from the lower slide piece, the lower slide piece is in contact with the lower roller and synchronously moves with the lower roller, and after the compressor starts, a lower cylinder and an upper cylinder perform compression normally to form double cylinders of the two-cylinder compressor; when the connector is locked with the lower slide piece, the lower slide piece is incapable of synchronously moving with the lower roller, compression cannot be performed, and the compressor is in a single-cylinder running mode that the upper cylinder performs compression. The connector can run accurately through guide of a thread by means of threaded connection, collision between the connector and the lower slide piece is avoided, and noise of the variable-capacity compressor is lowered.

Detailed description of the invention
Core of the present invention is to provide a kind of positive displacement compressor, to reduce the noise of positive displacement compressor. ThisAnother bright core is to provide a kind of refrigeration plant with above-mentioned positive displacement compressor.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried outDescribe clearly and completely, obviously, described embodiment is only the present invention's part embodiment, andNot whole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art are not doingGo out the every other embodiment obtaining under creative work prerequisite, all belong to the scope of protection of the invention.
As shown in Figure 2, the invention discloses a kind of positive displacement compressor, comprise 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, underRoller 19, lower slide plate 20, lower flange 21, permanent magnet 23, coil 24 and lower cover 25, and correspondingPosition and annexation all as depicted in figs. 1 and 2. The core of the positive displacement compressor in the applicationBe, also comprise installing hole and can lock and the connector 22 separating, this connector with lower slide plate 2022 can move by the axis direction along installing hole in installing hole, wherein, and this connector 22 and installing hole spiral shellLine connects. By installing hole and connector 22 are threaded, can be by rotating connector 22 companies of realizationThe movement of fitting 22 in installing hole, thereby connection and the release of the lower slide plate 20 of realization and lower roller 19.In the time that connector 22 separates with lower slide plate 20, lower slide plate 20 is contacted with lower roller 19 and with under rollSon 20 does followability motion, and after compressor start, lower cylinder 18 equally normally compresses with upper cylinder 14,Form the twin-tub of conventional duplex cylinder compressor; In the time that connector 22 and lower slide plate 20 are locked, lower slide plate 20 nothingsMethod and lower roller 19 do followability motion, and lower cylinder 18 is revealed, and do not compress compressor performanceFor the single cylinder operational mode that only has upper cylinder 14 to compress. The mode that employing is threaded can leading by screw threadTo and make the operation of connector 22 accurate, avoided the collision of connector 22 and lower slide plate 20, thereby fallenThe low noise of this positive displacement compressor.
In specific embodiment, above-mentioned connector 22 is defined as to pin, establishes by the periphery at pinPut screw thread, and corresponding setting with the screw thread of the threaded engagement of pin realized pin on the inwall of installing holeWith being threaded of installing hole. Direction for the screw thread of pin and installing hole is not specifically limited at this,As long as ensure that both are threaded. Compared with the gap that the pin that employing is threaded coordinates with installing holeOriginal pin of matched in clearance and the gap of installing hole are less, be threaded positive displacement compressor is transported at twin-tubThe seal with screwed joint better effects if of pin and installing hole when row mode, gas leakage amount is less. Twin-tub fortuneWhen row, its energy consumption is equal to common twin-tub efficiency, thereby improves the performance of compressor under twin-tub operation.
Further, in embodiment, this positive displacement compressor also comprises with connector 22 and being connected, for the company of drivingThe drive unit that fitting 22 moves in installing hole. Can avoid being manually rotationally connected by using drive unitPart, therefore, reduces operator's labour intensity.
In preferred embodiment, drive unit is set as to drive motors, under the effect of drive motors,Between pin and installing hole, be combined in proper order and separate, action accurately, has been avoided pin and lower slide plate 20Collide, reduced the noise of compressor. In addition, use the drive motors hydraulic motor of comparing can reduce listControl the pipeline of liquid to valve etc., therefore, cost-saved.
In one embodiment, drive unit is arranged on the lower cover 25 of this positive displacement compressor, thisPlace has only been to provide a kind of concrete installation site of drive unit, but in the application, is not limited in this positionPut, as long as can realize the movement of drive unit driving connector.
On the basis of technique scheme, in the application, disclosed installing hole comprises and being positioned on lower slide plate 20Linkage section and the set section that is positioned at the lower flange 21 contacting with lower slide plate 20, and linkage section and accommodatingDuan Liantong. In connector 22 moving process, in the time that connector 22 moves to linkage section, connector 22Lock with lower slide plate 20; When connector 22 departs from linkage section while being positioned at set section, connector 22 with glideSheet 20 separates.
In order further to optimize technique scheme, in the application, the diameter of disclosed linkage section is less than accommodatingThe diameter of section, and connector 22 has the clamping section that can coordinate with linkage section. By by above-mentioned installationHole and connector 22 are all set to the structure of variable cross-section further the movement of connector 22 is led,And variable cross-section also can limit the moving displacement of connector 22, prevent that connector 22 and lower slide plate 20 from clashing into.
In addition, disclosed herein as well is a kind of refrigeration plant, comprise positive displacement compressor, because this transfiguration is pressedContracting machine is disclosed positive displacement compressor in above-described embodiment, therefore has the refrigeration plant of this positive displacement compressorAlso have above-mentioned all technique effects, this is no longer going to repeat them.
In this description, each embodiment adopts the mode of going forward one by one to describe, and each embodiment stressesBe and the difference of other embodiment, between each embodiment identical similar part mutually referring to.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field can be realized or useThe present invention. To be aobvious and easy for those skilled in the art to the multiple amendment of these embodimentSee, General Principle as defined herein can be in the situation that not departing from the spirit or scope of the present invention,Realize in other embodiments.
