Counter clockwise direction one side of slide plate has the suction port 26 that is communicated with sucking pipe 2 in the described right end cap 8 corresponding cylinders, be arranged in clockwise direction one side of cylinder slide plate and the position of described suction port 26 symmetries on the described cover plate 11 and be provided with exhaust port 27, on the described exhaust port 27 outlet valve 20 is installed, described outlet valve 20 other cover plates are provided with by-pass port 21, distance between described exhaust port and the slide plate is less than the distance between by-pass port and the slide plate, make in the main axis rotation process and to pass through exhaust port more earlier through by-pass port.Offer exhaust cavity 16 between described left end cap 15 and the cover plate 11, the air outlet of described by-pass port 21 and outlet valve 20 is communicated with exhaust cavity 16 respectively, the position of corresponding cover plate upper air-vent 27 offers the exhaust hole 25 that is communicated with exhaust cavity on the left end cap 15, on the described left end cap 15 on the corresponding cover plate position of by-pass port 21 be provided with spring groove 23, be placed with the bypass valve block that circular bypass valve block is held out against on by-pass port in the spring groove 23 and hold out against spring 24, the relevant position that the bypass valve block holds out against spring, circular bypass valve block and left end cap and cover plate constitutes bypass valve.Left end cap 15 forms oil groove 14 with the space of an end of eccentric main axis 6 band oil ducts, and the neutral position, left side of left end cap 15 is welded with the fuel sucking pipe 13 that is communicated with oil groove 14, and fuel sucking pipe 13 stretches in the interior lubricating oil bath of casing, and eccentric oil duct 10 is communicated with oil groove 14.
During assembling, place gasket seal between suction port 26 welding sucking pipes, 2 backs on the right end cap 8 and the cylinder 17, cooperate with cylinder 17, sucking pipe 2 is passed casing 3 and casing 3 welding by the screw 7 in the screw hole 19.
It is sleeved 9 that eccentric main axis 6 eccentric part are overlapped, and will not have long end of oil duct to insert in right end cap 8 and the cylinder 17, is pressed into slide plate and holds out against spring and slide plate 1 in vane slot 18, slide plate 1 is positioned at the outside of eccentric rotor.
At the neutral position of left end cap 15 welding fuel sucking pipe 13.Above-mentioned integral body is pressed into the right side half housing of casing 3, the long end of eccentric main axis 6 cooperates with rotor 5, and rotor 5 is worked good with motor stator 4, with a left side half housing and the welding of right half housing, the bottom of casing 3 is installed and is looked oily mirror, injects from oil hole and calculates good lubricants capacity.With the connection box for motor location, to take over and outlet pipe 29 in casing 3 external welding technologies, the assembling of compressor complete machine finishes.Because outlet pipe 29 directly is not connected with exhaust hole 25, shell-side is the buffer space of high pressure refrigeration working medium, under the effect of shell-side high-pressure working medium pressure, lubricant oil in the casing 3 bottom lubricating oil baths is pressed into fuel sucking pipe 13, and enter oil groove 14, during eccentric main axis 6 high speed rotating, be positioned at the eccentric oil duct that the lubricant oil of oil groove 14 is offered along eccentric main axis 6 axial directions under action of centrifugal force, flowing to needs lubricated surface, the matching gap between obturator, reduces and leaks and frictional loss.
Gas refrigeration working medium by the next low-temp low-pressure of vaporizer enters in the aspirated volume space that is communicated with suction port by sucking pipe 2 by the suction port on the right end cap 8 26, the aspirated volume space turns over suction port, enter compression process, the outlet valve 20 of high temperature and high pressure gas refrigeration working medium after compression on cover plate 11 discharged and entered exhaust cavity 16, through entered the cavity of casing 3 behind the exhaust cavity 16 by exhaust hole 25, compressors are discharged by outlet pipe 29 in the back.
As shown in Figure 2, eccentric main axis 6 is done and is turned clockwise, and little space, the right side of crescent-shaped space is air-breathing, the little space compression in left side, eccentric main axis 6 continues rotation, and little space, right side is continued air-breathing, and the gas in the little space, left side is compressed to pressure is enough to back down corresponding outlet valve 20, gas is discharged, the little spatial volume in right side reaches maximum inhale and finishes, and eccentric main axis 6 drives the eccentric rotor rotation, turns over suction port 26, enter compression process, so go round and begin again.
Enter volume space as liquid together in company with gas, pressure in the volume space sharply raises, because of eccentric main axis 6 rotation elder generation process by-pass ports 21, the high pressure refrigeration working medium overcomes the resistance that the bypass valve block holds out against spring 24, back down bypass valve block 28, the high pressure refrigeration working medium by by-pass port 21, enter exhaust cavity 16, process exhaust hole 25 enters the space in the casing 3 again, pressure in volume space reduces, hold out against at the bypass valve block under the promotion of spring 24, bypass valve block 28 falls back on the by-pass port 21, and bypass valve cuts out.
The horizontal type rolling rotor compressor of band safety protective valve of the present utility model; utilize the by-pass port of offering high-pressure working medium on the rolling rotor refrigeration compressor end cap; anti-liquid hammer bypass valve is set; prevent the generation of liquid hammer accident; guarantee the reliability of refrigeration compressor and the ride quality of refrigeration system; reduce cost energy saving.And component structural is simple, and processing and assembling is convenient, and control flexibly, and is safe and reliable.
Although relate to a kind of horizontal type rolling rotor compressor and carried out special description disclosed with safety protective valve with reference to embodiment; embodiment described above is illustrative and not restrictive; under the situation that does not break away from spirit and scope of the present utility model, all variations and modification are all within scope of the present utility model.
