Lebaka la ho sisinyeha ha enjene le hlahlojoa ka botlalo

Ho ea kamochine o thothomelangmoetsi, sebopeho sa enjene se na le likarolo tsa motlakase le tsa mochini, kahoo liphoso tsa eona li lokela ho hlahlojoa ka likarolo tse peli.Lebaka la phoso ea ho sisinyeha ha enjene e arotsoe likarolo tse peli.

Ka kakaretso, ho sisinyeha ha enjene ho bakoa ke ho se leka-lekane ha likarolo tse potolohang, ho hloleha ha mochini kapa mabaka a motlakase.

1, karolo e potolohang ea ho se leka-lekane e bakoa haholo ke rotor, coupler, coupling, ho se leka-lekane ha lebili la phetisetso.

Tsela ea ho etsa sena ke ho fumana boemo bo ka holimo bo tlase.Haeba ho na le lebili le leholo la ho khanna, lebili la brake, coupler, coupling, le lokela ho arohana le rotor ho fumana tekanyo e ntle.Hape ke karolo e potolohang ea mochine o bakoang ke hlephileng.

2. Ho hloleha ha metjhini haholo-holo ho kenyelletsa tse latelang:

1) karolo ea khokahanyo ea shafting ha e nepahale, mohala o bohareng ha o lumellane, 'me centering ha e nepahale.

Lebaka le ka sehloohong la phoso ea mofuta ona ke mokhoa oa ho kenya, ho ba futsanehileng, ho kenngoa ho sa lokelang ho bakoang.

Ho na le nyeoe e 'ngoe, ke hore, karolo e itseng ea khokahano ea mohala o bohareng e lumellana le boemo bo batang, empa ka mor'a ho matha ka nako e itseng ka lebaka la fulcrum ea rotor, deformation ea motheo, mohala o bohareng o senyeha,' me kahoo o hlahisa ho thothomela.

2) ho na le ho hong ho phoso ka gear le coupling e hokahaneng le enjene. Phoso ena e bonahala haholo e le ho loma ka gear e mpe, ho roala meno ho tebileng, ho silafala ha lebili, ho kopa ho kopa, ho kheloha, sebopeho sa leino, sebaka sa leino. fosahetse, clearance e kholo haholo kapa apara e tebileng, e tla baka thothomelo e itseng.

3) mefokolo ea sebopeho le mathata a ho kenya mochini ka boeona.

Phoso ena e bonahala haholo-holo e le ellipse of shaft neck, ho kobeha ha shaft, sebaka se seholo haholo kapa se senyenyane haholo pakeng tsa shaft le sehlahla, ho satalla ho lekaneng ha setulo sa ho jara, poleiti ea motheo, karolo e itseng ea motheo esita le motheo oohle oa ho kenya motlakase, ho lokisoa ho hlephileng pakeng tsa. enjene le poleiti ea motheo, bolt e hlephileng ea leoto le ka tlase, e hlephileng pakeng tsa setulo se behang le poleiti ea motheo, jj.

Empa pakeng tsa shaft le bush clearance e kholo haholo kapa e nyane haholo eseng feela e ka bakang ho sisinyeha empa hape e ka etsa hore sehlahla sa lubrication le mocheso li hlahise se sa tloaelehang.

4) mojaro o khannoang ke enjene o tsamaisa thothomelo.

3, karolo ea ho hloleha ha motlakase e bakoa ke mabaka a motlakase haholo-holo a kenyelletsa: phoso ea khokahanyo ea ac motor stator, leqeba la asynchronous motor rotor winding short circuit, synchronous motor excitation winding interturn short circuit, phoso ea khokahano ea coil ea synchronous motor, cage asynchronous motor rotor e robehileng. , rotor core deformation e bakiloeng ke lekhalo le sa tšoaneng la moea, rotor, e lebisang ho se leka-lekaneng ha phallo ea moea e bakoang ke ho sisinyeha.
