Description
Technical field
The invention belongs to compressor mechanical technical fields, more particularly to a kind of Linearkompressor with fueller.
Background technique
Linearkompressor be it is a kind of using linear electric machine band piston move back and forth, thus will suck in cylinder interior
Gas compressed the device being then discharged.Relative to traditional reciprocating compressor, the linear compression with fueller
Machine eliminates the structure of crankshaft-link rod, reduces the quantity of drive mechanism, while decreasing rubbing between each driving member
It wipes.However rubbing surface is remained between piston and cylinder, in order to ensure Linearkompressor reliability of operation, generally also need
Lubricating oil to be provided between piston and cylinder by fueller.
Fig. 1 is a kind of Linearkompressor vertical structure cross-sectional view with fueller of prior art.As shown in Figure 1,
It includes shell, and bottom is equipped with lubricating oil；Main pump body, including linear electric machine, cylinder and piston, by damper with vibratile
Mode is set in shell；And fueller, it is arranged in main pump body lower part, including oil piston, oil cylinder.When with fueller
Linearkompressor work when, linear electric machine will carry out straight reciprocating motion with piston in cylinder, to realize gas
Sucking, compression and discharge process.Linear electric machine and cylinder can also vibrate together with piston simultaneously, and the vibration meeting of main pump body
It is transmitted to fueller, at this point, oil piston carries out straight reciprocating motion by being supported in oil cylinder for two sides oil spring, so that lubrication
Oil is inertially sucked and is discharged along with the reciprocating motion of oil cylinder.
It can be seen from described above in the Linearkompressor with fueller of prior art fueller power
It is mainly derived from the vibration of main pump body.However for the Linearkompressor with fueller with small vibration for main pump body, this
Fueller will be no longer applicable in.
To solve the above problems, Chinese patent CN108457810A proposes a solution.I.e. in fueller

Elastic stiffness wants small.Compressor mover is connected with oil pump mover by weak spring, so that the vibration of compressor mover be passed
Oil pump mover is given, to provide power for oil pump.However, this fueller has the following problems, it can by above description
Know, impulse stroke=compressor mover stroke-oil pump mover stroke of weak spring.It is well known that oil pump mover stroke relative to
For the movement travel of compressor mover very it is small, therefore the impulse stroke of weak spring almost with compressor mover stroke phase
Together, however the elastic stiffness of weak spring is far smaller than the elastic stiffness of compressor resonant spring, therefore, in compressor actual motion
In the process, there are a large amount of nonlinear motions, i.e., high harmonic motions for weak spring.A large amount of high harmonic motion transmission oil-feed pump mover will lead to
Oil pump feed is extremely unstable, will appear generation phenomena such as fuel feeding is insufficient or fuel feeding is excessive once in a while, living so as to cause compressor
It is worn between plug and cylinder and compressor performance declines, affect compressor reliability of operation.

Now the Linearkompressor course of work provided in this embodiment with fueller is described below:
When providing alternating current to stator coil 33, magnetic field will be generated in the annular gap of stator 31.Due to providing
Electric current be alternating current, the polarity in magnetic field is in cyclically-varying, so that the first permanent magnet 32a, the second permanent magnet 32b
Linear reciprocation is carried out on 21 inner surface of cylinder with frequency identical with provided electric current with piston 11 by mover skeleton 13
Movement.At this point, gas to be compressed will enter the inside of cylinder 21 by the inlet valve 12 being unlocked and be pressed by piston 11
Contracting.Wherein inlet valve 12 is to move back and forth the internal and external pressure difference generated by piston 11 to open and close.When in cylinder 21
When pressure reaches certain value, exhaust valve 22 will be opened in a manner of compression exhaust spring 23, at this point, the high pressure gas through overcompression
The outlet discharge on shell 00 will be passed through.It, will be with oily mover after a certain distance h when mover skeleton 13 moves right
Cushion film 43 on 41 contacts, so that oily mover 41 be driven to move right together, thus compressed oil spring 45.When piston 11 is run
To top dead-centre, the stroke of oily mover 41 reaches maximum at this time, and then, mover skeleton 13 and oily mover 41 are restored by oily spring 45
The effect of power starts to move downward together, and by certain distance Ao, oily mover 41 is separated with mover skeleton 13.Mover skeleton 13 after
It is continuous to move downward, and oily mover 41 is then blocked and stop motion by oily mover baffle 44.And so on, oily mover 41 with mover
The identical frequency of skeleton 13 carries out straight reciprocating motion in oil cylinder 42.
When oily mover 41 moves downward, pressure reduces in oil cylinder 42, and inside and outside differential pressure opens oil sucting valve 51, shell
The lubricating oil O of 00 bottom will be entered in oil cylinder 42 by suction passage 5a；When oily mover 41 moves right, pressure in oil cylinder 42
Increase, opened so that oil sucting valve 51 closes draining valve 52 simultaneously, the lubricating oil in oil cylinder 42 will enter work by oil drain passage 5b
In the gap of plug 11 and cylinder 21, to achieve the purpose that be lubricated piston 11 and cylinder 21.In addition, due to resonant spring
14 elastic stiffness is much larger than the elastic stiffness of oily spring 45, therefore it is minimum on the influence of the motion state of mover skeleton 13.
