PW160-7 Ivalve yoncedo 723-30-91200 excavator izincedisi eziphambili ivalve hydraulic impompo

Ivalve ye-solenoid isebenzisa i-electromagnetic ukutyhala undoqo wevalve ukulawula icala lomoya oxinanisiweyo, ngaloo ndlela ilawula icala ngakulo iswitshi ye-pneumatic actuator.
I-electromagnetic esetyenziselwa ukusebenzisa ivalve ye-solenoid yahlulwe ibe yi-AC kunye ne-DC:

1. Amandla ombane we-AC electromagnet ngama-220 volts. Ibonakaliswa ngamandla amakhulu okuqalisa, ixesha elifutshane lokubuyisela umva kunye nexabiso eliphantsi. Nangona kunjalo, xa undoqo wevalve ubambekile okanye ukufunxa akwanelanga kwaye umbindi wentsimbi ungafunxwanga, i-electromagnetic kulula ukutshisa ngenxa yangoku kakhulu, ngoko ke ukuthembeka kokusebenza kumbi, ifuthe lesenzo, kunye nobomi. iphantsi.

I-2.DC amandla ombane we-electromagnetic ngama-24 volts. Izibonelelo zayo ngumsebenzi othembekileyo, kungekhona ngenxa yokuba i-spore ixingile kwaye itshiswe, ubomi obude, ubungakanani obuncinci, kodwa amandla okuqalisa amancinci kune-electromagnetic ye-AC, kwaye ngokungabikho kombane we-DC, imfuno yezixhobo zokulungisa.
Ukuphucula ukuthembeka kokusebenza kunye nobomi bevalve ye-electromagnetic reversing valve, kwiminyaka yakutshanje, i-electromagnetic emanzi isetyenziswa kakhulu ekhaya nakwamanye amazwe, lo magnethi we-electromagnetic kunye nevalve yesilayidi ayifuni kutywinwa, ukuphelisa ukungqubuzana Umsesane wokutywina owenziwe nge-O, i-coil yayo ye-electromagnetic ngaphandle itywinwe ngokuthe ngqo ngeplastiki yobunjineli, hayi elinye iqokobhe lentsimbi, eliqinisekisa ukugquma, kodwa likwanceda ukutshabalalisa ubushushu, umsebenzi othembekileyo, Impembelelo ephantsi, ubomi obude.
Ukuza kuthi ga ngoku, ivalve ye-solenoid ekhaya nakwamanye amazwe yahlulwe ngokweendidi ezintathu ngokwemigaqo (ezizezi: uhlobo olusebenzayo oluthe ngqo, uhlobo lomqhubi wenyathelo lomntwana), kwaye ukusuka kumahluko wesakhiwo sediski yevalve kunye nezinto kunye nokwahluka komgaqo wahlulwe ngokweendidi ezintandathu. (isakhiwo se-diaphragm esisebenza ngokuthe ngqo, isakhiwo seplate ephindwe kabini, isakhiwo sefilimu ye-pilot, isakhiwo sepiston esisebenza ngokuthe ngqo, isakhiwo sepiston esisebenzayo, isakhiwo somqhubi wepiston).

Iivalvu zeCartridge zibonelela abaqulunqi bezixhobo ngeenzuzo ezininzi ngokwemiqathango yeebhloko zevalvu ezidityanisiweyo eziqhelekileyo:

1. Ibloko yevalvu edibeneyo yenkqubo yenza lula umbhobho womatshini.
Ukuyila ibloko yevalvu ukuhlangabezana neemfuno zesixhobo kungcono kunokuyila izixhobo zokuhlangabezana neemfuno zenkqubo yolwelo lwamanzi. Iindleko zokufakela zidla ngokuncitshiswa kakhulu

2. Yeka ukuvuza.
Ukuvuza kwangaphandle kudla ngokuba sesona sizathu siphambili sokusetyenziswa okulinganiselweyo kweenkqubo ze-hydraulic, kwaye i-O-ring efakwe kumngxuma wevalve kwibhloko yevalve edibeneyo inokuphelisa ukuvuza kwangaphandle.

3. Ixesha lokuphumla kunye nexesha lokugcinwa kwebloko yevalve edibeneyo ye-loop iyancitshiswa kakhulu, kwaye ukutshintshwa kwecandelo akuyi kuchaphazela umbhobho onxulumeneyo okanye awuyi kusonjululwa.
Uyahlula.

4. Isekethe edibeneyo ye-hydraulic ingabambiswa kwindawo enye kumatshini omnye okanye ihlakazwe kwiimfuno ezithile zokuphucula umbhobho.
Ngokuphathelele ukufakela, akukho mfuneko ethile yokufakela. Iibhloko zevalvu ezidityanisiweyo ezidityanisiweyo zibonelela ngokuguquguquka okungahambelaniyo
Ukwabelana ngesondo.
