Operating.
Below in conjunction with processing method of the drawings and specific embodiments to compressor arrangement proposed by the present invention and cylinder make into
One step is described in detail.According to claims and following explanation, advantages and features of the invention will be become apparent from.It should be noted that
Attached drawing is all made of very simplified form and using non-accurate ratio, only to convenient, lucidly aid illustration is of the invention
The purpose of embodiment.
Refering to fig. 1, show that the diagrammatic cross-section of cylinder head in this implementation, cylinder head 9 include: cylinder cap ontology
91 and the first adhesive layer 92 for being attached on 91 sealing surface of cylinder cap ontology.The sealing surface of cylinder cap ontology 91 assembly when and piston end
Face paste is closed, and has certain gap between the sealing surface and piston end surface of cylinder cap ontology 91.
In order to promote the adjustment of piston, the intensity of cylinder cap ontology 91 is greater than the intensity of the first adhesive layer 92, wherein first is attached
Layer 92 be phosphate coating, the thickness range of the first adhesive layer 92 is 1 μm~1000 μm.Further, the material of cylinder cap ontology 91
For cast iron or powder metallurgy.The thickness of first adhesive layer 92 can do specific design according to the model of cylinder, size.
Referring to Fig.2, it illustrates the diagrammatic cross-sections of rolling rotor compressor.
In more detail, cylinder head 9 has several mounting hole (not shown)s, for cylinder head 9 to be fixed on institute
On the cylinder to be assembled.The center of cylinder head 9 also has a circular through hole, and the output shaft of engine is logical across the circle
Hole, and it is fixed with the crankshaft 3 in compressor.
On the basis of above-mentioned cylinder head, the present embodiment also provides a kind of processing method of cylinder head 9, including following
Step:
Cylinder cap ontology 91 is formed, cylinder cap ontology 91 has a sealing surface；
The first adhesive layer 92 is formed on sealing surface.
Wherein, the first adhesive layer 92 is formed by phosphorating treatment.Certainly, the formation of the first adhesive layer 92 is not limited to phosphatization
Processing, the use other surfaces processing method that those skilled in the art can be quite reasonable.
Wherein, phosphorating treatment can be divided into according to phosphating solution ingredient: Zinc phosphating, Zinc-calcium series phosphatating, ferric solid-acid, manganese systems phosphorus
Change etc..The material for being formed by adhesive layer can also change with the change of phosphating solution ingredient.
After forming the first adhesive layer 92, keep the first adhesive layer 92 and cylinder cap ontology 91 stronger by local heat treatmet
It fits together.
Further combined with Fig. 2~3, the present invention also provides a kind of rolling rotor compressors, comprising: two cylinder heads 9,
One cylinder 1, a piston 2, a crankshaft 3, a slide plate 4 and an elastomeric element 5；Crankshaft 3 is set in cylinder 1, and 2 sets of piston in song

Slide plate 4 connects, and slide plate 4 contacts under the elastic acting force of elastomeric element 5 with piston 1.
In order to promote the adjustment of piston, the intensity of piston 2 is greater than the intensity of the first adhesive layer 92.
Another leak path of rolling rotor compressor is the gap between piston external diameter and cylinder bore diameter, in order to subtract
The leakage in the small gap can take same mode that the second adhesive layer is arranged on cylinder, specifically, cylinder 1 includes cylinder body
11 and the second adhesive layer 12 for being attached on 11 inner wall of cylinder body.The action principle of first adhesive layer 92 and the second adhesive layer 12
It is identical, it is all to reduce cylinder leakage under the premise of guaranteeing that piston 2 runs well, to improve the effect of rolling rotor compressor
Rate, so, the two can cross-reference in processing and design.
Wherein, piston 2 is bonded with cylinder inner wall, and can be rotated along cylinder inner wall, while slide plate 4 is in the bullet of elastomeric element 5
Property the active force lower moment keep contacted with piston 2, so as to form the high pressure chest 62 and low pressure chamber 61 in cylinder.
Specifically, the intensity of cylinder body 11 and piston 2 is all larger than 12 intensity of the second adhesive layer.In cylinder 1 and piston 2
In initial stage running-in time, piston 2 is rotated around crankshaft 3, and is rolled on 1 inner wall of cylinder, makes the local location of the second adhesive layer 12
Deformation, so that the second adhesive layer 12 be made gradually to tend to be round and smooth, finally makes the gap between piston 2 and cylinder 1 there is only very little, should
Gap is sealed by the refrigerator oil in cylinder.Second adhesive layer 12 is attached to cylinder sheet in cylinder body 11 after processing is completed
On 11 inner wall of body, thus the second adhesive layer 12 can eliminate cylinder body 11 process after existing surface polishing scratch, component precision and
The deformation of cylinder inner wall in assembling process.
In order to improve the abrasion performance of the second adhesive layer 12, and raising to the adsorptivity of refrigerator oil, the second adhesive layer
12 be phosphate coating.The thickness of second adhesive layer 12 is generally at 1 μm~1000 μm.Certainly, thickness is not limited thereto, this field
Technical staff can be according to the model size of specific compressor, and design requirement is appropriate to be sized.For example, for cylinder bore diameter
Biggish compressor, can increase the thickness of the second adhesive layer 12, and compressor lesser for cylinder bore diameter can reduce second
The thickness of adhesive layer 12.In addition, the thickness of the second adhesive layer 12 can also specifically determine most according to the compressor of different refrigerants, discharge capacity
Good size.
In order to further increase its sealing effect, the second adhesive layer 12 can be one layer, be also possible to multilayer, when comprising more
When the second adhesive layer 12 of layer, each layer of intensity is sequentially reduced along the direction of cylinder inner wall to piston.
In general, the material of cylinder body 11 is cast iron, formed by casting；The material of cylinder body 11 can also be powder
Metallurgy is formed by compacting sintering.Elastomeric element 5 can be spring.Further, piston 2 has an inner hole, and piston 2 passes through interior
Hole is placed on crankshaft 3, and can generate relative motion with crankshaft 3 in the running.
Further, which further includes intake valve 71, exhaust valve 72 and two end caps, intake valve
71 are set on air inlet 81, and exhaust valve 72 is set on gas vent 82, and two end caps are separately fixed at the both ends of the cylinder.
End cap is used for the both ends of sealing cylinder 1.
