Isincedisi se-excavator ye-hydraulic solenoid valve yoqobo TM68501 ivalve ye-solenoid elinganayo

Ivalve yesolenoid kwimpompo yehydraulic inezimbini, enye yiTVC solenoid valve, enye yiLS-EPC solenoid valve, eyeyangaphambili inoxanduva lokuva umqondiso wesantya senjini, ukulungisa amandla enjini kunye nepompo yehydraulic. amandla umdlalo, ukuba yonakele, nokuba injini izele yimoto, amandla angonelanga, okanye injini kunzima ukuqalisa.
Lo mva unoxanduva lokuqonda ukusebenza komqhubi kunye notshintsho kubungakanani bomthwalo wangaphandle, ukuba wonakele, kuya kubangela ubuthathaka ekumba, ukusebenza kancinci komatshini wonke, amandla amancinci okusebenza, kwaye akukho sixhobo sesantya esiphezulu. Kufuneka kuqatshelwe ukuba kukho i-valve ye-solenoid ye-TVC ngaphambi nangemva kwempompo, kunye ne-valve ye-solenoid ye-LS-EPC kuphela.
I-Hydraulic pump drive shaft ayikwazi ukumelana ne-radial force kunye ne-axial force, ngoko ke akuvumelekanga ukufaka amavili ebhanti, iigiya, ii-sprockets ngokuthe ngqo kwi-shaft end, ngokuqhelekileyo kunye nokudibanisa ukudibanisa i-drive shaft kunye ne-pump drive shaft.
Ukuba ngenxa yezizathu zokuvelisa, i-coaxial degree yepompo kunye nokudibanisa idlula umgangatho, kwaye kukho ukuphambuka ngexesha lokuhlanganisana, amandla e-centrifugal anyusa ukuguqulwa kokudibanisa kunye nokunyuka kwesantya sempompo, kwaye amandla e-centrifugal ayanda. Ukubangela umjikelezo okhohlakeleyo, umphumo wokungcangcazela kunye nengxolo, ngaloo ndlela uchaphazela ubomi benkonzo yempompo. Ukongeza, kukho ezinye izinto ezinempembelelo ezinje ngokudibanisa iphini lokukhulula kwaye hayi ukuqiniswa kwangexesha.

I-Excavator ye-electromagnetic relief valve fault kunye nendlela yokusombulula ingxaki:

1. Ukuguquguquka koxinzelelo lwenkqubo

Oonobangela abaphambili bokuguquguquka koxinzelelo zezi:
① Izikrufu ezilungelelanisa uxinzelelo zibangela ukuba i-nut yokutshixa ikhululeke ngenxa yokungcangcazela, okukhokelela kuxinzelelo lokuguquguquka;
② Ioli ye-Hydraulic ayihlambulukanga, kukho uthuli oluncinci, ukwenzela ukuba i-spool enkulu i-sliding ayiguquki. Isiphumo sokutshintsha koxinzelelo olungaqhelekanga. Ngamanye amaxesha i-valve iya ku-jam;
③ Eyona spool yevalve ayigudi, ibangela ukuba umngxuma wokudambisa uvaleke xa ugqithe;
(4) Umphezulu we-conical wombindi wevalve awudibani kakuhle nekhowuni yesitulo sevalvu, kwaye awugulwa kakuhle;
⑤ Umngxuma wokudambisa wesiseko sevalve engundoqo mkhulu kakhulu kwaye awudlali indima yokuthomalalisa;
Ivalve yokulinga ilungisa ukugoba kwasentwasahlobo, okukhokelela kuqhagamshelwano olungeluhle phakathi kwespool kunye nesitulo sekhowuni, ukunxitywa okungalinganiyo.
Isisombululo:
① Coca itanki yeoli kunye nombhobho rhoqo, kwaye ucofe ioyile yehydraulic engena kwitanki yeoli kunye nenkqubo yemibhobho;
(2) Ukuba kukho isihluzo kumbhobho, inxalenye yesihluzo sesibini kufuneka yongezwe, okanye ukuchaneka kohluzo lwecandelo lesibini kufuneka kutshintshwe; Ukuqhawula kunye nokucoca izakhi zevalve kwaye ubeke endaweni yeoli ecocekileyo ye-hydraulic;
③ Lungisa okanye utshintshe amalungu angafanelekanga;
④ Nciphisa indawo yokumanzisa ngokufanelekileyo.

g, ukunxitywa kweringi yerabha kwaye hayi ukutshintshwa ngexesha elifanelekileyo.
