Rotary compressor 100 according to embodiments of the present invention is described in detail below with reference to Fig. 1-Fig. 3, wherein rotary pressure
Contracting machine 100 can be single cylinder rotary compressor or multi-cylinder rotary compressor, i.e. cylinder 2 can be one or more.
It will also be appreciated that rotary compressor 100 can also be low back pressure compression in high back pressure compressor in housing or housing
Machine.
Rotary compressor 100 according to embodiments of the present invention, including：Housing 1, cylinder 2, bent axle 3, piston 4 and slide plate
5.Blast pipe 7 can be provided with wherein on housing 1.In the example of fig. 1, blast pipe 7 connects with the space in housing 1, that is,
Say, the rotary compressor 100 shown in Fig. 1 is high back pressure compressor in housing.
Cylinder 2 is located in housing 1, and cylinder chamber 20 and vane slot 21 are provided with cylinder 2.Bent axle 3 passes through cylinder chamber 20, bent axle
3 have the eccentric part 30 in cylinder chamber 20.Piston 4 is hollow-core construction, that is to say, that has cavity 40, piston in piston 4
It is enclosed on outside 4 on eccentric part 30 to drive rotation by eccentric part 30.As shown in figure 3, piston 4 has internal perisporium and periphery wall, inner circumferential
There is cavity 40 between wall and periphery wall.It is understood that the wall thickness of piston 4 should meet piston semi-finals degree requirement and piston 4
Structure design should meet resistance to pressure request (generally air-breathing and exhaust pressure difference).
Slide plate 5 is reciprocally slidably disposed within vane slot 21, and the tip of slide plate 5 contacts with the periphery wall of piston 4.Such as Fig. 1
Shown, rotary compressor 100 also includes motor 6, and motor 6 includes stator 61 and rotor 60, and stator 61 is fixed on the interior of housing 1
On perisporium, rotor 60 is rotatably arranged in stator 61, is enclosed on outside rotor 60 on bent axle 3 to drive bent axle 3 to rotate.
Because the piston of existing rotary compressor typically uses solid casting, weight is big, and price is high, and piston is in bent axle
Eccentric part, the quality of piston forms the major part of eccentric mass, and the balance that reducing piston weight can reduce on rotor is matched somebody with somebody
Weight, reduce cost, while reduce with the compressor eccentric mass of axis decentraction caused by centrifugal intertia force, so as to improve
The reliability of compressor.On the other hand, the function of piston is passing power (inner circle), compressed gas (cylindrical), structure compression
Chamber (cylindrical), end face seal (upper and lower end face), the sliding friction of slide plate tip is changed into rolling friction, and piston itself enters
Row revolution and rotation produce useless power consumption, and power consumption is related to piston weight, to unfavorable in terms of compressor performance.
The present invention by the design of hollow piston 4, can greatly reduce the weight of piston 4 (from the THICKNESS CALCULATION of existing piston,
The weight of half or so can about be reduced), the cost of piston 4 reduces, and the main balance weight counterweight of compressor can halve, and fits simultaneously
Hollow piston 4 and surface treatment when wall thickness, keep piston semi-finals degree, hardness and wearability.The eccentric mass for reducing compressor carries
High compressor reliability, while also reduce compressor piston 4 and run at high speed caused useless power consumption, improve compressor performance.
Rotary compressor 100 according to embodiments of the present invention, it is hollow-core construction by piston 4, can subtracts significantly
Few weight of piston 4, the cost of piston 4 reduce, and the main balance weight counterweight of compressor can halve, reduce the eccentric mass of compressor with
Compressor reliability is improved, while also reduces piston 4 and runs at high speed caused useless power consumption, improves compressor performance.
In some embodiments of the invention, piston 4 is stainless steel plate spinning product.Specifically, piston 4 can be technique
The surface treatment such as half smart part, nitriding and fine grinding are molded, meets that the requirement of the internal differential pressure of cylinder 2 and cylinder 2, the abrasion of the tip of slide plate 5 will
Ask.Of course, it should be understood that the processing technology not limited to this of piston 4, such as piston 4 can also be casting, specifically, piston
4 can be castings of gray cast iron or powder metallurgy casting.
As shown in figure 3, the inner circle of piston 4 has upper chamfering 42 and lower chamfering 43, further, the connection of piston 4 is synthesized
Seam is at the upper chamfering 42 or lower chamfering 43 of the inner circle of piston 4.So as to not influence the finishing of piston 4 and the assembling of piston 4.
According to some embodiments of the present invention, gas is filled with the cavity 40 of piston 4, the pressure of gas is positioned at rotary
Between the pressure of inspiration(Pi) and pressure at expulsion of compressor 100.It is understood that the pressure of inspiration(Pi) of rotary compressor 100 takes
What the span of value scope and pressure at expulsion was to determine, therefore the pressure of suitable gas can be selected to cause it between suction
Between atmospheric pressure and pressure at expulsion.Preferably, the stability of gas is high, such as the stabilizing gas that the perfusion coefficient of heat transfer is poorer than metal
(such as refrigerant).Of course, it should be understood that can also be normal pressure in the cavity 40 of piston 4.
Preferably, as shown in Fig. 2 the through hole 41 for the cavity 40 being communicated with piston 4 in piston 4, is set so as to pass through
Through hole 41 so that the cavity 40 of piston 4 is connected with compressor internal high pressure, can suitably reduce the resistance to pressure request of piston 4.Such as
Shown in Fig. 2, in some currently preferred embodiments of the present invention, the cavity 40 being communicated with the connecting sewing of piston 4 in piston 4 is synthesized
Through hole 41, consequently facilitating the machine-shaping of piston 4.
As shown in figure 1, in some embodiments of the invention, rotary compressor 100 is high back pressure compressor in housing,
Vane slot 21 connects with the space in housing 1, so that the pressure in vane slot 21 is high pressure, it is ensured that the elder generation of slide plate 5
End is only against on the periphery wall of piston 4 all the time.
