Insurance damage喝議
After turning on the mac費就hine, such as the disc理東overy of no power display, no action, t也內he first thing to look at the powe算行r supply seat within 林喝the insurance is damaged.
Analysis and judgment: it is possibl個很e that the user ground wire子中 and the fire wire 學煙or zero wire mixed, and not grounded話明 (the machine g筆議round is connected to the machine shell兵微), there may be a short circuit in t草北he machine, compone到文nts aging short-circuit phenomenon, r計員esulting in damage to the insurance.
Detection and solution: take out t車為he fuse to see if there is 愛鐵a fracture, use th問門e multimeter through the broken 算市file to measure whether to disc你業onnect, replace the new device
Transducer damage
Analysis and judgment: may be due to a 黃歌long time in the open use state, the黃得 temperature will graduall空樹y rise leading to alternating melting 信森words can go off or 快鄉words can go to the ceramic花對 part of the fracture.
Detection and solution: Us聽場e a shaking table to measur算民e the insulatio校又n strength of the words 綠樂to go, insulation stren頻和gth below 200M, has b服鄉een unable to use, must b錢時e replaced by a 站北new transducer. Because t你章he internal ceramic of the transducer 員唱will also be due to long-term use of fr區見acture, can not work properly.&nb低村sp;
Power tube damage
Analysis and judgment: the power生線 tube on the motherboard will be b是房ecause of the machine for a long time w內書ithout interruption, or t討體oo little cleaning fluid 們人for a long time, the報在 power tube short-circuit situation.票友
Detection and sol煙去ution: gear power 從快tube connected to the motherb房現oard, using a multimeter to m河長easure the resistance of the power間技 tube pins on both sides, under norm謝站al circumstances should be abou有女t 22, after taking down the power嗎技 tube (disconnecte玩務d from the motherboard), m話章easuring its vario劇村us pins should not be connec樂現ted between.
Damaged voltage regulator現森
Analysis and judgment: damage to th麗西e voltage regulator is general都很ly caused by a small re高坐sistance or short ci樹街rcuit in the power tube科和, after the power on, itself rarely dam姐生aged.
Detection and sol也內ution: According 要鄉to the characteri你長stics of the diode, positiv近請e conduction, reverse as of. Mea風看sured with a multimeter diode fil用刀e, the forward resistance valu上河e of about 70, reverse 土影∞. If the value deviation冷但 is too large or for藍著ward resistance value is also ∞購都, replace the new volt嗎白age regulator.
Bridge damage (d請光iode rectifier circui聽通t)
Analysis and judgment: the same regu黑得lator condition
Detection and sol子白ution: the same accordin國弟g to the diode characte技麗ristics (the bridge it讀電self is compose讀弟d of diodes)
Damage to the control舊山 board (adjustable ultrasonic c放相leaner)
Analysis and judgment: long continuous 還金work, components aging related, or som知明etimes infiltrate cleaning fluid請裡 related.
Detection and solution: in the machi吃公ne does not work 北工state, disconnect the contr銀村ol board and the motherb外器oard, the motherboard energ校現ized, such as the machine wor員那ks, it means that the control board is 通飛damaged and needs to be到火 replaced.
Inductance, iso空文lation transformer dama訊了ge
Analysis and judgment: Du低她e to the long wor話站king hours of the machine, inducto亮玩rs, transformers belong to和年 the heat dissipation com現農ponents, its own may b吃明e too high tempe雜舞rature two melted, burne海但d, resulting in short circuit.
Detection and solution: induc務計tor, transformer da生腦mage, in most cases intuitively c員麗an see the trace員北s of burned, replace the new devi姐放ce
