[introduction]
The summer uses the season with most frequent air conditioning, but some cars advocate had encountered certainly open air conditioning to hear appearance stage interior to appear bored " Zhi Zhi abnormal knocking " . Go perhaps maintaining inn majority to be able to be informed to 4S inn attaint of air conditioning electric machinery, cannot maintain can change only. Change expense is little criterion hundreds of yuan many criterion thousands of yuan. Change still feel distressed purse, do not change ceaseless still abnormal knocking. To this kind of circumstance, experienced worker instructs you a few court today, let electric machinery of yourself maintenance air conditioning, below relaxed province hundreds of yuan.
One, what require a tool
1, screwdriver
2, wool is brushed
3, air gun
4, clear lotion
5, grease
2, the common breakdown of electric machinery
1, short circuit / open circuit
In-house electric machinery damages, bring about circuit open circuit or short circuit, occurrence insurance burns caustic or electric machinery does not run wait for a problem.
2, abnormal knocking
When movement, electric machinery appears " Zhi Zhi " abnormal knocking.
3, rotate speed is slow
Locomotive speed under booked standard speed a lot of.
3. Tear open the note of outfit
Of air conditioning electric machinery tear open outfit is not complex, because the design of every model is different, elaborated more nevertheless here. But a bit need to notice, the fan leaf of air conditioning electric machinery secures nut majority to be designed for contrary whorl, anticlockwise when disassemble it is close solid, suitable hour hand is to become loose.
4, clean measure
1, purge fan page
Use for a long time, the meeting on fan leaf is adherent have a large number of dirt, if dirt is overmuch, can bring about fan movement dynamic balancing to miss difference, cause shake or abnormal knocking. Above all we should clear namely fan lamina, use wool brushs ash of float of sweep off surface, use clear lotion to be clear about stubborn dirt next.
2, disassemble electric machinery
Disassemble electric machinery very be cautious, after disassembling blade, can get on electric machinery basically from housing disassemble angle. And disassemble after fan lamina, we can see the bearing on electric machinery, they are main abnormal knocking sources.
3, clean bearing
Use ready clear lotion, clean electric machinery bearing. Bearing of general electric machinery is to cannot be decomposed. When we are cleaned, also do not want too thorough, should clean exterior float ash only can.
4, blow dry bearing
Use air gun blows the clear lotion on electric machinery bearing dry.
5, check carbon brush
Electric machinery rear has carbon brush, it is in charge of the normal movement of electric machinery. In cleaning a process, we open carbolic brush rocker, can see carbon brush length, if pass short, need changes in time.
6, impact lube
Use lube is lubricant axis of rotor of ministry of bearing less than. Impact quantity passes not easily big. 1-2 drips can.
7, use grease is sealed
Grease has lubricant effect not only, still have sealed effect, in bearing outer lane our daub a few grease. OK and effective sealed bearing, avoid dirt to enter bearing interior.
Write finally:
From the point of afore-mentioned measure, of air conditioning electric machinery maintain not complex. Have a bit commonly start work the person of ability can undertake maintaining, calculate you to cannot disassemble by oneself, be in after encountering this kind of problem, we can let maintain inn to give disassemble, oneself undertake maintaining. Can remain hundreds of yuan upkeep probably.
