I-Excavatator ilayisha i-punier gun gun valve 708-1w-04850

Njengeveli engafakwanga njenge-valve engayiphathi kakuhle:

I-valve yolawulo lwezinto ezininzi zelifansi ePhakamileyo nePhakathi isetyenziswa njenge-valve yolandelelwano yokuvelisa uxinzelelo lwasemva (umtya kwisekethe yeoyile yokubuyisa).

Ivalve yoNcedo lwePilot inamacandelo amabini: ivalve ephambili kunye ne-valve ye-pilot. I-valve ye-pilot ziyafana ne-valves yokusebenza ngokuthe ngqo eyalelayo, kodwa zihlala zevalve (okanye i-valve yebhola) ye-valve). Ivalve ephambili inokwahlulwa ibe yindawo enye, ubume obubini bokuxilongo kunye nobume obuphindwe kabini.

Emva kwe-PC200-6 ngokupheleleyo i-chcavaud iqalile, isixhobo esisebenzayo sinokufumana iintshukumo ezahlukeneyo, kodwa impompo eziphambili ithumela ingxolo engaqhelekanga.

Ngokutsho kohlalutyo lwangaphambili, kukholelwa ukuba impompo icinyiwe okanye isekethe yeoyile ixutywe nomoya. Ke ngoko, kuqala uhlengahlengise isixhobo esisebenzayo kwindawo yokufumana i-oyile, kwaye ujonge ukuba inqanaba le-oyile letanki ye-hydraulic ingezantsi kwenqanaba eliphantsi lethagethi yeoyile, eso sikhundla sokunqongophala kweoyile. Emva kokubuza umqhubi, iringi yokutywina ye-oyile ephezulu ye-oyile ekhokelela kwigumbi le-rod ye-rod yebhakethi lathathelwa indawo ngenxa yokuvuza ioyile ngenxa ye-oyile, kodwa inqanaba leoyile alikhange lifunyanwe ngexesha emva kokutshintsha. Ke ngoko, kuqala, itanki ye-hydraulic ilele kwinqanaba leoyile esemgangathweni, kwaye uvavanyo lubonisa ukuba ingxolo engaqhelekanga incitshisiwe, kodwa isekhona; Emva koko, ngokusebenzisa i-vamp enkulu yempompo ukuya kwimpompo ephambili emva kovavanyo oluphambili, kufumanisa ukuba ingxolo engaqhelekanga isekhona, ebonisa ukuba ingxolo ayinakubangelwa yimpompo yempompo.

Okulandelayo, isihluzi se-oyile kunye nelitha le-oyile yetanki ye-hydraulic ijongiwe, kwaye ifunyenwe ukuba isihluzi se-oyile simnyama kwaye sinodaka lwe-oyile, kwaye amasuntswana entsimbi emdaka anamathele kwilitha le-oyile. Ukuqwalaselwa kukuba kukho amasuntswana entsimbi emdaka ejongene kwifilitha yeoyile yokubuya, ioyile yempompo ephambili ikhutshelwe kwaye ihlolwe, kwaye ifunyenwe ukuba kukho amasuntswana entsimbi emdaka; Kwangelo xesha, xa impompo eziphambili yayiyeyona nto iphambili yaye yahlolwa, yafunyanwa ukuba ipleyiti ye-piston, ipleyiti ye-vash kunye nentsimbi yeSwesh ayizange ichaphazele. Emva kokungeniswa kwayo, indibano yayenziwa ngokungqongqo ngokungqinelana neemfuno, inkqubo ye-hydraulic yasuswa kwaye ioyile yatshintshwa, kwaye xa kwakuqala ioyile, kwaye ingxolo engaqhelekanga yanyamalala.

Phantsi kweemeko eziqhelekileyo, oonobangela bokubangela ingxolo engaqhelekanga ejikeleze impompo ephambili yile ilandelayo:

I-hydraulic ye-hydraulic ibangela ukuba impompo iphambili; Umoya uxutywe kumgca we-suction; Ibhloko yefiltha ikhokelela kwimpompo yempompo eyintloko; Ukunxila ngaphakathi kwepump enkulu kubangela ingxolo engaqhelekanga ekusebenzeni kwempompo ephambili.

Kule meko, ingxolo engaqhelekanga ibangelwa yioyile ye-hydraulic kunye nokunxibisa i-slipper ngaphakathi kwempompo ephambili. Isizathu kukuba inqanaba leoyile alikhange lihlolwe ngexesha emva kokutshintshwa kwetywina, kubangela ioyile ye-hydraulic, ukuze impompo iphambili ivelisa i-phenomenon; Xa i-oyile ixutywe nomoya ihamba ngepumps ephambili, i-slipper ayinakho ukubhabha okanye ihamba kancinci kwamanye amaxesha, okukhokelela kwipleyiti ye-oyile, eyenza ukuba i-slipper inxibe kwaye ekugqibeleni ibangela ingxolo engaqhelekanga
