Description
Technical field
The present invention relates to reciprocal compressor, relate in particular to its oil supply unit of lubricating oil.
Background technique
In general, compressor is the device that is used for constituting cooling cycle system, and it is discharged after the refrigeration agent that flows into its inner low-temp low-pressure state from vaporizer can being compressed into high-temperature high-pressure state.
Above-mentioned compressor can be divided into rotary compressor, reciprocal compressor, spool (scroll) compressor etc. according to the mode of compressed fluid.Particularly above-mentioned reciprocal compressor is that linear motion by piston sucks and pressurized gas.Such reciprocal compressor can be divided into following several mode substantially again, promptly rotatablely moving of drive motor is converted to the to-and-fro motion of piston, thereby sucks the also mode of pressurized gas; Straight reciprocating motion by drive motor also moves back and forth piston, thereby sucks the also mode of pressurized gas.
As shown in Figure 1, existing reciprocal compressor is by constituting with lower member: casing (10), and a certain amount of lubricant oil is equipped with in its bottom, and gas suction pipe (SP) and the gas outlet pipe (DP) that is connected with external component is housed above it; Frame assembly (20), it keeps necessarily flexibly being installed in the inside of said machine casing (10); Reciprocable machine (30), it is fixed on the said frame assembly (20), but and its mover (33) can do straight reciprocating motion; Compression assembly (40), it be connected above-mentioned reciprocable machine (30) but mover (33) on, and be subjected to the support of frame assembly (20); Resonant spring assembly (50), it can be at reciprocable machine (30) but the moving direction of mover (33) on it is given elastic support, thereby cause resonance motion; Lubricant oil fuel feeding assembly (60), it is installed on the said frame assembly (20), the lubricant oil (O) that is stored in casing (10) inside can be transported to the sliding position of compression assembly (40).
Said frame assembly (20) is by forming with the bottom: preceding square bearer (21), and it is supporting above-mentioned compression assembly (40); Central frame (22), it is connected on the above-mentioned preceding square bearer (21), is supporting the front end of reciprocable machine (30); Back square bearer (23), it is connected on the central frame (22), is supporting the rear end of reciprocable machine (30).
Above-mentioned reciprocable machine (30) is by forming with the bottom: outer stator (31), and it is installed between preceding square bearer (21) and the central frame (22); Inside stator (32), it keeps certain intervals ground to be connected with outer stator (31), and insertion is fixed in the back square bearer (23); But mover (33), it is installed between outer stator (31) and the inside stator (32), can do straight reciprocating motion.
Above-mentioned compression assembly (40) is by forming with the bottom: cylinder (41), and it and preceding square bearer (21) are integrally formed; Piston (42), it be connected above-mentioned reciprocable machine (30) but mover (33) on, can in the compression volume (P) of cylinder (41), move reciprocatingly; Suction valve (43), it is installed in the front end of above-mentioned piston (42), can make the suction passage (F) of piston (42) realize opening and closure, and control the suction of refrigerant gas thus; Discharge valve assembly (44), it is installed in the discharge side of cylinder (41), can make compression volume (P) realize opening and closure, and controls the discharge of refrigerant gas thus.
Above-mentioned resonant spring assembly (50) is by forming with the bottom: but be connected spring support member (51) on the joint of mover (33) and piston (42); With spring support member (51) is that intermediate support is at the place ahead in its place ahead resonant spring (52); With spring support member (51) is that intermediate support is at the rear at its rear resonant spring (53).
Above-mentioned lubricant oil fuel feeding assembly (60) is by forming with the bottom: lubricant oil suction section (61), it is installed in the lower end of frame assembly (20), can vibrate with said frame assembly (20), and in vibration, lubricant oil (O) suction of casing (10) bottom can be come up; Lubricant oil oil supply gallery portion (62), it is gone up at said frame assembly (20) and forms, and the outlet of lubricant oil suction section (61) is connected with compression assembly (40).
As shown in Figure 2, lubricant oil suction section (61) is by forming with the bottom: lubricated oil cylinder (61A), and it is installed in the lower end of preceding square bearer (21); Lubricant oil sucks lid (61B) and lubricant oil is discharged lid (61C), and they are installed in the front end and back end of lubricated oil cylinder (61A) respectively; Lubricant oil piston (61D), it is inserted in the inside of lubricated oil cylinder (61A) and can slides, and lubricant oil (O) suction can be come up; Lubricant oil spring (61E) (61E), they are supporting the two ends of lubricant oil piston (61D) respectively; Lubricant oil suction valve (61F), it is installed between lubricant oil piston (61D) and the lubricant oil spring (61E), can control the suction of lubricant oil (O); Lubricant oil expulsion valve (61G), it is installed in preceding square bearer (21) and lubricant oil is discharged between the lid (61C), can control the discharge of lubricant oil (O).In addition, also comprise lubricant oil suction pipe (61H), its end is connected above-mentioned lubricant oil by the method that is pressed into and sucks in the lubricant oil suction port (61I) on the lid (61B), and the other end is inserted in and is stored in the inner lubricant oil (O) of said machine casing (10).
Above-mentioned lubricant oil oil supply gallery (62) is by forming with the bottom: lubricant oil inlet hole (62A), and framework (21) and lubricant oil are discharged between the lid (61C) and are formed, an and lower inner surface through to cylinder (41) forwardly for it; Oil groove (pocket) (62B), it is that outer surface along piston (42) caves inward and forms, and is connected with lubricant oil inlet hole (62A); Lubricant oil tap hole (62C), it is connected with above-mentioned oil groove (62B), the first half that leads to preceding square bearer (21) from the upper inside surface of cylinder (41).
Have a look the course of action of existing reciprocal compressor below with said structure:
If be installed on the reciprocable machine (30) in the reciprocal compressor and connected power supply, thereby between outer stator (31) and inside stator (32), formed magnetic flux (flux), be placed on above-mentioned outer stator (31) and inside stator (32) so but between the space in mover (33) can move along the direction of magnetic flux, and under the effect of resonant spring assembly (50), can move back and forth constantly.Piston (42) can move back and forth in the inside of cylinder (41) thus, and the volume of compression volume (P) is changed, thereby be drawn into refrigerant gas in the compression volume and compressed, and then discharge, and this a series of action can be carried out repeatedly.
In this process, the vibration that the lubricated oil cylinder (61A) of lubricant oil suction section (61) is produced in the time of can be along with piston (31) to-and-fro motion and vibrating, and in vibration lubricant oil piston (61D) can be under action of inertia the lubricant oil that casing (10) is inner aspirate (pumping) by above-mentioned lubricant oil suction pipe (61H) and come up.These lubricant oil can flow through lubricant oil expulsion valve (61G), then in lubricant oil oil supply gallery (62) flows into lubricant oil inlet hole (62A) and oil groove (62B), thereby play the effect of the sliding position between lube pistons (42) and the cylinder (41).
Afterwards, lubricant oil can flow back into casing (10) inside along lubricant oil tap hole (62C), thereby is recovered.
But, in the reciprocal compressor of aforesaid existing structure, because being used for sucking the length of the lubricant oil suction pipe (61H) that is stored in the inner lubricant oil of casing (10) fixes, if therefore its length is oversize, moving and during the transportation reciprocal compressor so, it may be with casing (10) thereby bumps damage; If but length is too short, lubricant oil suction pipe (61H) may not reach again and is stored in the inner lubricant oil of casing (10), and can not suck lubricant oil, and then just can not make lubricant oil successfully flow to the position of needs to play lubrication yet.The existing problem of reciprocal compressor of Here it is existing structure.
Summary of the invention
