Description
(1) technical field:
The present invention relates to a kind of double-rolling rotor compressor.Belong to mechanical volume type rotary compressor.
(2) background technique:
Rolling rotor type compressor is also claimed rolling piston type refrigerating compressor; Being widely used in family expenses and business air conditioner, the refrigeration plant, is that a kind of rolling rotor that relies on off-centre to be provided with is made rolling motion in the cylindrical shape cylinder and the to-and-fro motion with the contacted slide plate of rolling rotor realizes the refrigeration compressor that gas compresses.At present widely used mainly is small-sized totally-enclosed formula; Usually there are horizontal and vertical two kinds; It mainly is made up of liquid-storage container, seal container and the motor part and the press part that are arranged in the seal container; The stator of motor is fixed in the seal container, and motor rotor is connected on the eccentric shaft, and liquid-storage container plays gas-liquid separation, store refrigerant liquid and lubricant oil and the pulsation of buffering pressure of inspiration(Pi).
The basic structure of above-mentioned press part is:
It mainly is made up of columnar cylinder, eccentric shaft, the spring that is arranged at columnar rolling rotor, slide plate and back thereof on the eccentric shaft, metal (upper, outlet valve etc.Rolling rotor off-centre is arranged in the cylindrical shape cylinder; Cylinder face and rotor outer surface just form a crescent-shaped space, on cylinder, have a radial groove, and slide plate is housed in the groove; Lean on the active force of spring; The slide plate end closely contacts with rotor, and crescent-shaped space is divided into two-part, on the casing wall near the slide plate both sides, offers suction port and exhaust port.Suction port communicates with segment space, is called air aspiration cavity, and exhaust port communicates with segment space, is called exhaust cavity.Along with the rolling of rolling rotor, air aspiration cavity that is separated by slide plate and the spatial volume in the compression chamber constantly enlarge and dwindle, thereby accomplish the working procedure of compressor.
Compare with Reciprocting piston compressor, rolling rotor type compressor have component few, simple in structure, reliable, do not have a suction valve chip; Clearance volume is little; The gas transmission coefficient is high, under identical cold situation, the characteristics of aspect such as the compressor volume is little, in light weight, but this compressor has only a rotor and is arranged off-centre; The vibration that works together is big with noise, and load change greatly, dynamic balance is poor.
For this reason, the double-rotor rolling rotor compressor has appearred, and as shown in fig. 1; It mainly is made up of liquid-storage container, seal container and the motor part and the press part that are arranged in the seal container; The stator of motor is fixed in the seal container, and motor rotor is connected on the eccentric shaft, and press part is made up of the spring at upper and lower cylinder, metal (upper, intermediate clapboard, eccentric shaft, rolling rotor, slide plate and back thereof, outlet valve etc.; Through being fixedly connected motionless intermediate clapboard from spaced intermediate with two cylinders up and down; Form upper and lower two compression units, the center of intermediate clapboard has the eccentric wheel axis hole, and eccentric shaft passes from above-mentioned eccentric wheel axis hole; Upper and lower two eccentric wheels of eccentric shaft are 180 ° of balanced configurations, are installed on rolling rotor on the eccentric wheel and are mutually 180 ° phase difference with relative rotation and move.
In the said structure; During motor work, drive eccentric shaft and tubular rolling rotor and roll along cylinder face, the refrigeration agent gas gets into liquid-storage container by suction tude; Get into air aspiration cavity by the suction port on the cylinder then; Refrigeration agent gas is after compression entered in the seal container by outlet valve, and the air gap through between motor rotor and stator is discharged from the top outlet pipe of casing again, and the air gap of refrigeration agent gas through between motor rotor and stator played the effect of cool motors simultaneously when discharging.
Double-rotor rolling rotor compressor balance the unbalance inertia force of compressor drum; Make the on-stream radial force of rotor obtain balance, the variation of load torque is tended to be steady, simultaneously; Compressor has twice suction, exhaust in rotor rotates a circle; The pressure surge of gas is reduced, and the stationarity of compression process has had improvement, and its vibration and noise are greatly improved.Duplex cylinder compressor more and more widely is applied, and is particularly useful for frequency conversion drive.
However, existing double-rotor rolling rotor compressor still has following deficiency:
1. well-known, refrigeration agent in the past such as CFC and HCFC etc. can bring destruction to ozonosphere, all to progressively be eliminated, and present alternative refrigerant such as HFC and CO
2All need bigger exhaust pressure; Bigger exhaust pressure is easy to cause the eccentric shaft distortion of press part; Especially connect this section between upper and lower two eccentric wheels; The eccentric shaft distortion will cause rotor tilt, and this has caused the end face generation frictional loss of rotor with respect to the sealing cylinder part on the one hand, has increased power loss; Simultaneously, cause the abrasion of parts, shortened the compressor life-span.The double-rotor rolling rotor compressor of existing structure can't adapt to the alternative refrigerant of the bigger exhaust pressure of these needs.
2. existing double-rotor rolling rotor compressor all need use outlet valve, and outlet valve not only increases resistance, has caused power loss, can send noise simultaneously, especially an easily damaged parts.Especially the defective of outlet valve is more outstanding under fast state.
3. in order to improve motor efficiency; Gap between motor rotor and the stator is generally all smaller; And the air displacement of double-rotor rolling rotor compressor is generally all bigger; Bigger air displacement is difficult to through less motor rotor and the gap location between the stator, and this has just caused high pressure gas after compression can not in time discharge compressor.
