Abstract
A start-up auxiliary device of a shunt-wound compressor comprises a first compressor and a second compressor which are connected in parallel. The first compressor is started first, and a solenoid valve is arranged inside a communicating pipeline arranged between a high-voltage outlet and a low-voltage inlet of the second compressor. The high-voltage outlet of the first compressor is communicated to an inlet end of a first retaining valve through a first oil separator, the high-voltage outlet of the second compressor is communicated to the inlet end of a second retaining valve through a second oil separator, an exit end of the first retaining valve is connected in parallel with the exit end of the second retaining valve; one end of a first capillary is communicated to the first oil separator, the other end is communicated to the low-voltage inlet of the first compressor; and one end of a second capillary is communicated to the second oil separator, the other end is communicated to the low-voltage inlet of the second compressor. In order to ensure that the back start-up compressor is started without a load, the start-up auxiliary device is arranged on the compressor to keep the balance of the high-low voltage before starting, thereby ensure the security and reliability of the overall system.
Description
Technical field
The utility model relates to a kind of startup servicing unit of compressor in parallel, particularly a kind of compressor in parallel.
Background technology
To the air-conditioning system of forming by two compressors in parallel, by controlling the unlatching of two compressors, thereby satisfy different air conditioner load requirements.Disclose the dual controller of compressor bank in parallel in a kind of refrigeration plant among the Chinese patent literature CN2529166Y, comprised mechanical control circuit and electronic control circuit, be provided with switching relay and alarm relay between two kinds of control circuits; Switching relay and alarm relay are realized being electrically connected with mechanical control circuit and electronic control circuit.The dual controller of this structure is difficult in real work guarantee that the compressor that the back starts is not hit, and might cause compressor destroyed, and the security of its whole system and reliability are all lower.
The utility model content
The purpose of this utility model aims to provide the startup servicing unit of the compressor in parallel of the preceding high-low pressure balance of a kind of compressor start simple and reasonable, that the back starts, non-loaded startup, to overcome weak point of the prior art.
Press the startup servicing unit of a kind of compressor in parallel of this purpose design, comprise first compressor and second compressor in parallel, first compressor at first starts, and its architectural feature is to be provided with magnetic valve in the connecting pipeline between the high-pressure outlet of second compressor and the low-pressure inlet.
The high-pressure outlet of described first compressor is communicated to the entrance point of first check valve through first oil eliminator, the high-pressure outlet of second compressor is communicated to the entrance point of second check valve, the port of export parallel connection of the port of export of first check valve and second check valve through second oil eliminator; First end capillaceous is communicated to first oil eliminator, and its other end is communicated to the low-pressure inlet of first compressor; Second end capillaceous is communicated to second oil eliminator, and its other end is communicated to the low-pressure inlet of second compressor.
The low-pressure inlet of the low-pressure inlet of described first compressor and second compressor is parallel to low-pressure liquid storing tank.
When the utility model requires two compressors all to open at air conditioner load, for the non-loaded startup of compressor that guarantees that the back starts, prevent that compressor from burning out, on this compressor, increase and start servicing unit, with its high-pressure outlet and low-pressure inlet by the connection of switching on of a magnetic valve, make this compressor before starting, keep the high-low pressure balance, afterwards the magnetic valve outage is started second compressor, the non-loaded startup of compressor with back startup in the abundant assurance compressor in parallel, prevent that compressor from burning out, thereby guarantee the security and the reliability of whole system.
Description of drawings
Fig. 1 is the utility model one example structure schematic diagram.
Among the figure: 1 is first compressor, and 2 is second compressor, and 3 is magnetic valve, and 4 is first check valve, and 5 is low-pressure liquid storing tank, and 6 is first oil eliminator, and 7 is first capillary, and 14 is second check valve, and 16 is second oil eliminator, and 17 is second capillary.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, the startup servicing unit of this compressor in parallel, comprise first compressor 1 and second compressor 2 in parallel, first compressor 1 at first starts, be provided with magnetic valve 3 between the high-pressure outlet of second compressor 2 and the low-pressure inlet in the connecting pipeline, magnetic valve 3 energisings are communicated with high-pressure outlet and low-pressure inlet, and magnetic valve outage afterwards starts second compressor 2.The high-pressure outlet of first compressor 1 is communicated to the entrance point of first check valve 4 through first oil eliminator 6, the high-pressure outlet of second compressor 2 is communicated to the entrance point of second check valve 14, the port of export parallel connection of the port of export of first check valve 4 and second check valve 14 through second oil eliminator 16; One end of first capillary 7 is communicated to first oil eliminator 6, and its other end is communicated to the low-pressure inlet of first compressor 1; One end of second capillary 17 is communicated to second oil eliminator 16, and its other end is communicated to the low-pressure inlet of second compressor 2.The low-pressure inlet of the low-pressure inlet of first compressor 1 and second compressor 2 is parallel to low-pressure liquid storing tank 5.
Claims (3)
1. the startup servicing unit of a compressor in parallel, comprise first compressor (1) and second compressor (2) in parallel, first compressor at first starts, and it is characterized in that being provided with magnetic valve (3) in the connecting pipeline between the high-pressure outlet of second compressor and the low-pressure inlet.
2. according to the startup servicing unit of the described compressor in parallel of claim 1, it is characterized in that the high-pressure outlet of described first compressor is communicated to the entrance point of first check valve (4) through first oil eliminator (6), the high-pressure outlet of second compressor is communicated to the entrance point of second check valve (14), the port of export parallel connection of the port of export of first check valve and second check valve through second oil eliminator (16); One end of first capillary (7) is communicated to first oil eliminator, and its other end is communicated to the low-pressure inlet of first compressor; One end of second capillary (17) is communicated to second oil eliminator, and its other end is communicated to the low-pressure inlet of second compressor.
3. according to the startup servicing unit of the described compressor in parallel of claim 2, it is characterized in that the low-pressure inlet of described first compressor and the low-pressure inlet of second compressor are parallel to low-pressure liquid storing tank (5).
