Description
Technical field
The present invention relates to air compressor machine technical field, more particularly to a kind of sliding-vane compressor.
Background technology
The main frame of sliding-vane compressor is made up of rotor and stator, and some longitudinal cunnings are wherein uniformly provided with rotor
Groove, slide plate in chute slidably；Stator is a cylinder, and rotor is eccentric in the stator to be placed, when the rotor rotates, slide plate
It is thrown out of in chute under the influence of centrifugal force and with stator by oil film close contact, two neighboring slide plate and stator inner wall
Between form an air chamber for closing, as air compression chamber, when rotor is rotated, the volume of air compression chamber is skidded off with slide plate
The size of amount and change, in breathing process, air is inhaled into compression chamber via filter, and with spray into the lubricating oil in main frame
Mixing, in compression process, the volume of compression chamber is gradually reduced, and pressure gradually rises, and gas mixture passes through exhaust outlet afterwards
Discharge.There is following several shortcomings in existing sliding-vane compressor：（1）, the chute in rotor be linear pattern, arrange to meet in the past
The demand of tolerance must increase the relatively radially value of chute and necked part, in order to ensure the fluency of total, outward appearance
Aesthetic etc., the necked part of two ends of rotor reduces, and causes two ends of rotor necked part weak easily broken.（2）, conventional rotor
On chute in there is no oil groove, the lubricating difficulties between slide plate knife face and rotor, its lubrication channel is that slide plate both sides are moistened
After cunning, unnecessary oil flows to slide plate knife face, belongs to two grades of feed lubrications, and this is accomplished by the oil of abundance, in fuel feeding somewhat deficiency
In the case of, slide plate knife face just has the danger of oil starvation, and the slide plate knife face that cannot be lubricated will be produced to rotor under the action of the centrifugal force
The big impact of life.（3）, in use at the two ends of chute easily form impacting with high pressure, its temperature is increased.（4）In the past
Directly coordinate between end cap and rotor, in piston machine start-up course, before lubrication pressure is not set up fully, rotor does and rotates
Motion, end cap is maintained static, and is existed between rotor end-face and end cap and is contacted and in dry condition, unavoidably causes mill
Damage, once having, gap will be formed between abrasion rotor and end cap, cause leakage, cause the discharge capacity index of compressor to decline, it is interior
Portion's power consumption increases, and current pre- antiwear measure is the material for using anti-wear performance good, and end cap is a big part, using wearability
The good material of energy, its cost can be very big, and end cap is limited with the mating surface of rotor by processing conditions in itself, and precision is difficult to protect
Card.（5）, when intake valve work it is abnormal when, when slide plate or rotor machining precision do not reach or occurs mistake oil condition under abrasion
When, air inflow is more than capacity, and pressure drastically elevated phenomenon can be produced in internal suction and discharge passage, and oil and gas path work is not smooth,
Stress can be uneven during exercise to cause slide plate.
