Description
Technical field
The present invention relates to a kind of rotary compressor, particularly relate to a kind of double-rotor rotary compressor.
Background technique
In general, compressor is a kind of machine of compressed fluid.This compressor is by the seal container with certain inner space, is installed in the electromechanical part that can produce driving force in the seal container and can utilizes the driving force of electromechanical part and the compression mechanical portion of compressed fluid constitutes.Wherein the compression mechanical portion in the double-rotor rotary compressor comprises two cylinders.Fig. 1 is the double-rotor rotary compressor longitudinal construction sectional view of prior art.As shown in Figure 1, the seal container of the double-rotor rotary compressor of this prior art is made of cylindrical housing 3 and loam cake 4 and lower cover 5.One side of shell 3 is provided with two refrigerant imports 1,1 ' that link to each other with two exhaust ports in liquid container 6 bottoms 7,7 ' respectively, and the center portion of loam cake 4 then vertically is provided with refrigerant exit 2.The electromechanical part on seal container top mainly by be fixed on cylindrical housing 3 inwalls stator 11 and the center of stator 11 and can by and stator 11 between the rotor 12 that is rotated of electromagnetic action form.The compression mechanical portion that is positioned at the seal container bottom comprises mainly that then setting along the vertical direction and centre are spaced from each other by dividing plate 8, and a side be respectively equipped with shell 3 on refrigerant import 1, first cylinder 9 and second cylinder 9 ' of the 1 ' cylinder air inlet 17,17 ' that links to each other; Be installed in the upper bearing 10 on first cylinder, 9 end faces; Be installed in the lower bearing 13 on second cylinder, the 9 ' bottom surface; Run through rotor 12 and first, second cylinder 9,9 ' center, the bottom is formed with two respectively with first, the corresponding eccentric part 14,14 ' in the position of second cylinder 9,9 ', can together rotate with rotor 12, thereby the rotating force that electromechanical part can be produced pass to the bent axle 15 of compression mechanical portion; Be with the outside of two eccentric parts 14,14 ' on the bent axle 15 respectively and can be respectively be rotated with the first, the second of compression refrigerant and roll ring 16,16 ' in the inside cavity of the first, the second cylinder 9,9 '.When the double-rotor rotary compressor of this prior art moves, the rotor 12 at seal container central upper portion position will by and stator 11 between electromagnetic action carry out high speed rotating, drive simultaneously to run through the bent axle 15 at its center and to be enclosed within two of bent axle 15 bottoms and roll ring 16,16 ' also together rotates, thereby self-circulation system and difference are passed through two exhaust ports 7 of liquid container 6 bottoms in succession in the future, 7 ', refrigerant import 1,1 ' and cylinder air inlet 17,17 ' and enter first, second cylinder 9,9 ' inner refrigerant compresses, refrigerant through overcompression will drain into the inside of shell 3 from the exhaust port on not shown upper bearing 10 and the lower bearing 13 then, at last from the refrigerant exit 2 that is arranged in loam cake 4 center portions and be expelled back into the circulatory system.But there is following point in the double-rotor rotary compressor of this prior art: as mentioned above, shell 3 is provided with two refrigerant imports 1,1 ', because required operation easier is big during simultaneously to these two hole punching presses on shell 3, and assemble first, second cylinder 9, also need in the time of 9 ' two cylinder air inlets 17, with two refrigerant imports 1, align exactly between 1 ' between 17 ' and respectively, the bottom of liquid container 6 also needs two exhaust ports 7 of relative set in addition, 7 ', Jia Gong difficulty height so not only, thereby the up-to-standard rate of product is lower, and also cost of production also can correspondingly raise.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of machining operation that is easy to, the simple in structure and double-rotor rotary compressor that can reduce production costs.
In order to achieve the above object, double-rotor rotary compressor provided by the invention comprises seal container, electromechanical part and compression mechanical portion; Wherein seal container is made of cylindrical housing and loam cake and lower cover, and a side of shell is provided with a refrigerant import that links to each other with liquid container bottom exhaust port, and the center portion of loam cake then vertically is provided with refrigerant exit; Electromechanical part is positioned at the top of seal container, mainly by be fixed on the cylindrical housing inwall stator and the center of stator and can by and stator between the rotor that is rotated of electromagnetic action form; Compression mechanical portion is positioned at the bottom of seal container, mainly comprise along the vertical direction being provided with and middlely being spaced from each other, and a side is provided with first cylinder and second cylinder of the cylinder air inlet that vertically runs through dividing plate when linking to each other with refrigerant import on the shell and communicate with each other by dividing plate; Be installed in the upper bearing on the first cylinder end face; Be installed in the lower bearing on the second cylinder bottom surface; The center of running through rotor and the first, the second cylinder, bottom be formed with two respectively with the corresponding eccentric part in the position of the first, the second cylinder, can together rotate with rotor, thereby the rotating force that electromechanical part can be produced pass to the bent axle of compression mechanical portion; Be with the outside of two eccentric parts on the bent axle respectively and can be respectively be rotated with the first, the second of compression refrigerant and roll ring in the inside cavity of the first, the second cylinder.
Described liquid container bottom is provided with an exhaust port.
Double-rotor rotary compressor provided by the invention is that the method that the cylinder air inlet utilization that will be arranged on two cylinder one sides runs through dividing plate communicates with each other, so only need a refrigerant import just can satisfy the requirement of two cylinders, and adopt common liquid container to get final product, thereby can save raw material and processing charges.In addition and since do not exist when assembling need with between a plurality of cylinder air inlets and respectively and between a plurality of refrigerant import accurately to direct problem, so the difficulty of processing is low, thereby can improve the quality and the up-to-standard rate of product.
