Description
Technical field
The invention belongs to the Linearkompressor technical field, particularly relate to a kind of device of the friction portion fuel feeding for cylinder in Linearkompressor and piston.
Background technique
The compressor that the tradition chiller plant adopts is to utilize turning motor, adds that a cover will rotatablely move to be converted to reciprocating crankshaft-linking rod drive mechanism and to come the pushing piston compression refrigerant gas.Because each member is made complexity, and can produce friction between member, therefore, the Efficiency Decreasing of compressor, power consumption is large.
Linearkompressor adopts permanent magnet and the linear motor of coil groups to replace crank mechanism and electric rotating machine, makes reciprocating motion of the pistons come compressed refrigerant.Linearkompressor is by the quantity of minimizing dirivig member, thus the friction between the minimizing member.Be the energy loss that further reduces to rub and cause, usually also need the friction portion supplying lubricating oil between the member with relative movement, conventional piston formula compressor adopts the fuel feeding that rotatablely moves, and this fuel system is not suitable for Linearkompressor.
Linearkompressor can have multiple oil supplying device, and it is for the piston of lubricate compressors and the friction portion between cylinder that oil supplying device is provided, and makes piston movement more smooth.Figure 1 shows that a kind of Linearkompressor with oil supplying device in prior art.This compressor set C is arranged in a seal container V, and its underpart has been full of lubricant oil, is used for suction, compression and discharging refrigerant; Oil supplying device O is fixed on the bottom of compression set C, is used for the friction portion fuel feeding to structural member.
Existing compression set C comprises the frame 1 that is arranged on airtight container V inside, and cylinder 2 is positioned at the central position of frame 1; Piston 3 inserts cylinder 2 inside, and linear electric motor compressor C makes horizontal back and forth movement; The rear end part of piston 3 is connected with magnet 7, and the end that seal container V inside has 9, two groups of piston springs 9 of two groups of piston springs props up supporting element 8, and the front end of piston spring 9 is the end of support piston 3 flexibly; But the front end of cylinder 2 is provided with the exhaust cap 5 of switch, is provided with outlet valve 4 in this exhaust cap 5, and this outlet valve 4 is along with the back and forth movement of piston 3 can be opened or closed cylinder 2.
The first oil groove 2a is positioned on the inner circumferential surface of through hole of frame 1, and oil inlet passage 1a is communicated with the first oil groove 2a with the discharge side of oil supplying device O.Form the second oil groove 3a on the outer round surface of piston 3.Form through hole 4a on cylinder 2, make the first oil groove 2a be communicated with the second oil groove 3a.Have at the top of the first oil groove 2a by the outer round surface of cylinder 2, the through hole of frame 1 and the oily circulation canal 1d that exhaust cap 5 forms, this passage 1d is communicated with oily passage 1c.Foot at oily circulation canal 1d is provided with oil drainage hole 1e, makes the oil by oily passage 1d circulation return to airtight container V.
Fig. 2 is the vertical section figure of the oil supplying device of Linearkompressor of the prior art.Oil supplying device O comprises: the oil cylinder 21 that is fixed on compression set C bottom; Insert the piston 22 in oil cylinder 21, this piston 22 is divided into oil suction space S 1 and oil extraction space S 2 to the inside of oil cylinder 21; The first spring 23A and the second spring 23B, difference is supporting piston 22 two ends flexibly, and piston 22 is pressed to oil cylinder 21; Oil suction lid 24 and oil extraction lid 25 are respectively used to support the other end of the first spring 23A and the second spring 23B, and respectively the two ends of oil cylinder 21 are fixed on compression set C; Oil sucting valve 26 is located between the outlet and the second spring 23B of piston 22, and by the second spring 23B supporting; And be positioned at the second spring 23B the other end and be arranged on the draining valve 27 that 25 inside are covered in oil extraction.
According to the general work process of Linearkompressor, piston 3 is done to-and-fro motion uninterruptedly in cylinder 2, loops flowing to, compress and discharging of refrigerant gas.At this moment, when compression set C vibrates together with magnet component in the horizontal direction along with the linear reciprocating motion of magnet component 7 (being the rotor of linear motor), simultaneously vibration is passed to the oil supplying device O that is fixed on compression set C and drive oil supplying device O and move reciprocatingly.At this moment, piston 22 makes lubricant oil along with the to-and-fro motion of oil cylinder 21 is sucked and discharges by inertia in the interior slip of oil cylinder 21.
For oil sucting valve 26 is arranged in oil cylinder 21, the shape that limited oil sucting valve 26 generally adopts spiral-shapedly, inserts in oil cylinder 21, and is withstood tightly the exit portion of piston 22 by the second spring 23B.Simultaneously, draining valve 27 is rectangular, is attached on the outer surface of oil cylinder 21 oil extraction sides, by 25 supportings of oil extraction lid.
At present, because the oil sucting valve of controlling the oil turnover in the oil supplying device of existing Linearkompressor will be arranged in the less oil cylinder of diameter, need the oil sucting valve of small volume to satisfy installation requirement, and be arranged on in-oil cylinder oil sucting valve and have certain shape, the oil sucting valve manufacturing of small volume and the difficulty of assembling are larger.In addition, because must adopting larger pressure, the oil suction lid inserts the end of resilient member, so that the piston that is positioned in the middle of resilient member has enough large stretching elasticity, but this kind assembly method difficulty is larger, limited the flexible elastic force of piston, thereby limited suction and the discharge capacity of lubricant oil, reduced manufacturing efficiency.
