Embodiment
Below in conjunction with accompanying drawing, the direct-connected rotary compressor of the present invention is described in further detail.
Direct-connected rotary compressor is by motor, Electric Machine Control assembly 4 and rotary compressor composition, described motor is by rotor 8, motor shaft 7, major part such as motor stator 6 grade forms, described motor shaft 7 is integral type with rotary compressor live axle, motor driving force directly passes to rotary compressor by motor shaft 7, motor can be direct current generator, also can be AC motor, described Electric Machine Control assembly 4 is connected with electric machine casing, be conducive to the heat radiation of Electric Machine Control assembly, described rotary compressor part is primarily of front cover 2, rear end cover 9, compresser cylinder 10, compressor drum 11, slide plate 3, composition such as motor shaft 7 grade.
Motor shaft 7 is as the driving element of compressor, being connected with compressor, part is made as one section of eccentric shaft, its throw of eccentric is 1/2 of the difference of compresser cylinder diameter of bore and compressor drum outside diameter, compressor drum is by the eccentric position of bearing housing at motor shaft 7, compressor drum 11 cylindrical and compresser cylinder 10 inwall tangent, slide plate 3 one end is hinged in a circular hole of compresser cylinder, and the other end of slide plate 3 is inserted in the skateboards slot of compressor drum 11.
During direct-connected rotary compressor work, switch on power, motor shaft 7 rotates, eccentric part on motor shaft 7 drives compressor drum 11 to rotate, because the inwall of compresser cylinder 10 is tangent with the outer wall of compressor drum 11 all the time, therefore, the outer wall of compressor drum 11 and the inwall of compresser cylinder 10 just constitute a meniscate active chamber, and slide plate 3 is separated into air-inlet cavity and exhaust cavity two-part meniscate active chamber in operation process, what be connected with intake duct is air-inlet cavity, and what be connected with air outlet flue is exhaust cavity.
When compressor drum 11 counterclockwise rotates from position shown in Fig. 2, the volume of air-inlet cavity increases gradually, refrigerant gas through intake duct 5, communication channel routed over electrical machine stator gap, rear end cover suction port enters compressor air-inlet cavity; Meanwhile, the volume of exhaust cavity then diminishes gradually, and gas is compressed, and when its pressure meets or exceeds relief opening outside pressure, exhaust starts.
When again getting back to position shown in Fig. 2 after compressor drum 11 rotates, the volume of air-inlet cavity increases to maximum, and intake process terminates; Meanwhile, the volume of exhaust cavity reduces to minimum, and exhaust process also terminates, and completes a work cycle.And the next work cycle that brings into operation.
Because intake process and exhaust process are synchronously carried out, the flow velocity of its air inlet and exhaust reduces, thus flow losses also reduce greatly, flow losses are about the half of reciprocal compressor, volumetric efficiency is significantly improved, during working rotor due to the direct-connected rotary compressor of the present invention, both ends of the surface are not by the effect of axial force, therefore compressor drum both ends of the surface axial force is minimum, compressor drum both ends of the surface and the wearing and tearing between front cover and rear end cover also minimum, minimum gap is had between compressor drum cylindrical and compressor stator, therefore it is stressed minimum, fretting wear is also minimum, speed of related movement between skateboards slot and slide plate is minimum, therefore the fretting wear between them is also minimum.What is more important, motor shaft 7 and compressor shaft are integrated, and are the radial clearance uniformity of a moving element axis, overcome the eccentric wear phenomenon between component, reduce fretting wear, save power loss.The suction port of compressor is arranged on motor side, refrigerant gas through intake duct 5, communication channel routed over electrical machine stator gap, rear end cover suction port enters compressor air-inlet cavity, reduce the operating temperature of motor stator 6 and rotor 8, improve working conditions of motor, extend the operating life of motor.Great advantage of the present invention is that the fretting wear that can realize between each moving parts is minimum as can be seen here, the mechanical efficiency of compressor can be improved to greatest extent, part processing of arriving involved in the present invention is simple in addition, be easy to form batch production, cost of production can significantly reduce, therefore volume comparatively reciprocal compressor minimizing 50-60%, weight about alleviates about 60%, and indicated efficiency improves 30-40% than piston type.
