Description
Technical field
The present invention relates to compressor, relate in particular to a kind of seal clearance and preferable lubrication effect that can guarantee minimum, effectively improve the lubrication sealing structure of the rotary compressor cylinder of compressor volume efficient.
Background technique
Air conditioner is will be by compressor, condensing machine, expansion gear, vaporizer circuit refrigerant, carry out heat exchange with air by vaporizer after, interior space air is carried out a kind of device that changes in temperature are regulated.The structure of air conditioner comprises, outdoor unit that constitutes by compressor, condensing machine and expansion gear and the indoor set that constitutes by fan and vaporizer, outdoor unit and indoor set between interconnect by coolant piping.
Usually according to the form of the compressor section of compressed fluid, compressor is divided into rotor-type compressor (rotary Compressor), reciprocating movement type compressor (reciprocating Compressor), screw axis compressor (Scroll Compressor) etc.
General rotary compressor is as the machine that is used for compressed fluid.The structure of compressor is made of seal container (housing), mechanism portion (motor) and compressor section (pump housing).Seal container is the enclosed cavity with certain inner space, and compressor section (pump housing) and mechanism portion (motor) are installed in wherein, is full of pressurized gas in the seal container (housing); Mechanism portion is made of stator and rotor, is installed in the seal container, is used for producing the required driving force of rotation; Compressor section obtains the driving force of mechanism portion, pressurized gas.
In the compression mechanical part of existing rotary compressor, be formed with inner space (cylinder), and have the suction passage that is connected with the inner space respectively and discharge stream; The center, inner space of the cylinder assembly body of secure bond in seal container is penetrated with running shaft, and running shaft is combined on the mechanism portion; This running shaft is the bent axle with eccentric structure, rolls ring set and is located at crankshaft eccentric portion; The cylinder assembly body comprises as lower member: cylinder, upper bearing and lower bearing; The cylinder outer circumferential face is weldingly fixed on the seal container, and cylinder interior has the penetration hole of drum; Upper bearing and lower bearing cover respectively on the top and bottom that are combined in cylinder, form the inner space with cylinder, and supporting rotating shaft.Be formed with suction passage on the cylinder, this suction passage runs through formation towards outer circumferential face with radiation from the inner space of cylinder.
Consult shown in Figure 1, the lubrication sealing structure of rotary compressor cylinder of the present invention, its cylinder is the fish tail shape, be to form by the mould compacting, it comprises: cylinder block 1, the cylinder block front top is provided with inlet hole, exhaust port, and front end is provided with baffle plate groove 11, is provided with the baffle plate 12 that the cylinder operation chamber is separated into air aspiration cavity and exhaust cavity in the baffle plate groove 11; Front end two outer side surfaces are complicated curvilinerar figure, and cylinder block 1 is provided with several bolt apertures that combines with upper bearing and lower bearing; The cylinder block tail end is provided with positioning hole, and tail end two outer side surfaces are outward-dipping shape; Rolling ring 13, to be positioned at cylinder working chamber indoor.
The working procedure of compressor is to suck low-pressure gas by suction side, is rotated motion by the integral body of rolling ring and bent axle formation, so that low-pressure gas is compressed into pressurized gas, is discharged by the relief opening that is installed in the cylinder upside then.It is very fast that compression process is carried out, and what can be similar to regards as adiabatic process with compression process.The rotor hot charging of motor is rotated motion with bent axle on the major axis of bent axle, thereby changes the cylinder chamber body bulk, with low-pressure gas boil down to pressurized gas.Drive the rotation of pump housing eccentric part along with running shaft, the ring that rolls that combines with eccentric part also rotates, the rotation of rolling ring promotes baffle plate and moves back and forth in the baffle plate groove of the pump housing, with cylinder cavity separated into two parts, reach compression, that is, roll ring and whenever turn around refrigerant, baffle plate is once moved back and forth in baffle plate groove, thereby finish compression process one time.Compressor is finished whole compression process and then must be moved and the change cavity volume by cooperatively interacting between bent axle and rotor, thereby reaches the purpose that changes gas pressure intensity in the cavity.The sealing of gas in the cylinder, and lubricated between the friction means be the key factor that guarantees compressor operating efficient and reliability, existing compressor adopts the mode of perfusion lubricant oil in cylinder to carry out the sealing of gas, and to lubricating between the friction member, avoids taking place boundary friction.After in cylinder, pouring into lubricant oil, can make and roll ring surface and baffle surface formation one deck oil film, can make the gap between baffle plate 12 and the baffle plate groove 11 reduce to play simultaneously lubrication by this oil lamella, avoid or reduce the probability of the direct leakage and the generation boundary friction of gas.But this mode lubricated and sealing has defective; because when compressor carries out work; baffle plate is aprowl with rolling ring all the time; the situation of oil film appears forming in its surface through regular meeting; boundary friction problem between direct leakage that will produce gas under the situation of no oil film and friction means; therefore, await improving and overcome the problem that exists in the lubricated and sealing of compresser cylinder.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that existing product exists, a kind of lubrication sealing structure of rotary compressor cylinder is provided, one deck solid lubricant layer is established in its baffle plate outer surface plating that will be arranged in the cylinder block front end baffle plate groove, to be positioned at the indoor ring outer surface that rolls of cylinder working chamber also plates and establishes one deck solid lubricant layer, the effect of the lubricated and buffering ambient pressure that has by solid lubricant itself, make baffle plate and roll ring and adjust by the oneself and avoid taking place at the volley the boundary friction problem, reach compresser cylinder and have minimum seal clearance, improve volumetric efficiency, guarantee the effect of compressor operating efficient and reliability.
The objective of the invention is to realize by following technological scheme.
The lubrication sealing structure of rotary compressor cylinder of the present invention, the lubrication sealing structure of rotary compressor cylinder comprises cylinder block, and the cylinder block front end is provided with baffle plate groove, be provided with the baffle plate that the cylinder operation chamber is separated into air aspiration cavity and exhaust cavity in the baffle plate groove, rolling ring, to be positioned at cylinder working chamber indoor; It is characterized in that: one deck solid lubricant layer is established in described baffle plate outer surface plating; Describedly roll ring outer surface plating and establish one deck solid lubricant layer.
