Summary of the invention
The present invention proposes a kind of minisize refrigeration compressor, its good airproof performance, and reliability is high.
Technological scheme of the present invention is achieved in that a kind of minisize refrigeration compressor, comprise motor section and the compression assembly installed in airtight housing and the housing, described compression assembly two ends are fixed by main bearing and supplementary bearing, described compression assembly comprises the cylinder with the cylinder compression chamber, the built-in roller bearing piston of described cylinder and slide plate, main bearing and supplementary bearing support bent axle, and described slide plate is resisted against the periphery of roller bearing piston.Described housing comprises main casing and upper shell, the part that described main casing is connected with upper shell and upper enclosure inner wall seal welding, the central position sealing interlocking of described upper shell is useful on and connects power supply to the power supply plug of motor section power supply, and upper shell arranges the part indent of outlet pipe; Be provided with the air-breathing base of seal welding on the described main casing, be sealedly connected with the sucking pipe that is communicated with cylinder in the described air-breathing base, connect gas holder behind the described sucking pipe crankle.
The technical program, by main casing and upper enclosure inner wall seal welding, the sealing of power supply plug is rabbeted on upper shell, air-breathing base and sucking pipe seal welding, these designs have all ensured the sealing of compressor, and then resistance to pressure is enhanced to adapt to new cooling media to the requirement of container pressure.Outlet pipe is arranged on the female parts of upper shell, can reduce the volume of whole compressor, saves the space.Be communicated with gas holder behind the sucking pipe crankle, need compressed gas in gas holder, to be cushioned, avoid the uneven situation that just directly enters cylinder of air pressure.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of a kind of minisize refrigeration compressor of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technological scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiments.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment who obtains under the creative work prerequisite.
A kind of minisize refrigeration compressor, its structure as shown in Figure 1, comprise motor section and the compression assembly installed in airtight housing and the housing, described compression assembly two ends are fixing by main bearing 7 and supplementary bearing 9, described compression assembly comprises the cylinder 8 with the cylinder compression chamber, described cylinder 8 built-in roller bearing piston and slide plates, main bearing 7 and supplementary bearing 9 support bent axle 6, described slide plate is resisted against the periphery of roller bearing piston, described housing comprises main casing 1 and upper shell 2, the part that described main casing 1 is connected with upper shell 2 is welded with upper shell 2 inner wall sealings, the central position sealing interlocking of described upper shell 2 is useful on and connects power supply to the power supply plug 11 of motor section power supply, and upper shell 2 arranges the part indent of outlet pipe 3; Be provided with the air-breathing base 15 of seal welding on the described main casing 1, be sealedly connected with the sucking pipe 12 that is communicated with cylinder 8 in the described air-breathing base 15, connect gas holder 14 behind described sucking pipe 12 crankles.
In the technical program, by main casing 1 and the welding of upper shell 2 inner wall sealings, the 11 sealing interlockings of power supply plug are on upper shell 2, air-breathing base 15 is tightly connected with sucking pipe 12, these designs have all ensured the sealing of compressor, and then resistance to pressure is enhanced to adapt to new cooling media to the requirement of container pressure.Outlet pipe 3 is arranged on the female parts of upper shell 2, can reduce the volume of whole compressor.Be communicated with gas holder 14 behind sucking pipe 12 crankles, need compressed gas in gas holder 14, to be cushioned, avoid the uneven situation that just directly enters cylinder 8 of air pressure.
Outer surface at bent axle 6 has spiral helicine oil groove, and convenient oiling agent water conservancy diversion with housing bottom is to bent axle 6 and each slide member.
The motor of described motor section is DC permanent magnetism synchronous machine, comprises stator 4 and rotor 5 among Fig. 1, and this kind motor volume is little, and quality is light, and efficient is high, is applicable to micro-compressor.Be fixed electrical machinery, the stator 4 of motor is fixedly connected with main casing 1 inwall interference, this kind installation also is conducive to antivibration, and in use size error is subjected to thermal effect less simultaneously.
The outer side surface of described cylinder 8 and the welding of main casing 1 wall, as can be seen from Fig. 1, the position, outer side surface Range compress chamber of the cylinder 8 of weld is far away, introduces the excessive size error when avoiding welding, and affects the normal operation of slide plate and compression chamber.
15 of described sucking pipe 12 and air-breathing bases are provided with bushing pipe 16, because sucking pipe 12 is all harder with the material of air-breathing base 15, so adopt intermediate seal layer bushing pipe 16 to guarantee sealing effect, and can avoid outlet pipe 12 directly to be connected the damage that is subject to air-breathing base 15.Sucking pipe 12 stretches into and is set in the gas holder 14, and sucking pipe 12 inserting ends and gas holder 14 axles are obliquely installed, and can avoid sucking pipe 12 to suck the liquid that gases carry and enter cylinder 8 compressions.
