TM1005110 24V excavator hydraulic impompo ivelufa proportional solenoid

Umahluko phakathi kwevalve yombane elinganayo kunye nevalve ye-solenoid

Ulawulo lwevalve lokuhamba lunokwahlulwa lube ziindidi ezimbini:
 

Olunye lulawulo lokutshintsha: nokuba luvuleke ngokupheleleyo okanye luvalwe ngokupheleleyo, umlinganiselo wokuhamba ungowona uphezulu okanye ubuncinci, akukho mbuso uphakathi, njengombane oqhelekileyo we-electromagnetic ngokusebenzisa ivalve, ivalve yokubuyisela umbane ye-electromagnetic, ivalve ye-electro-hydraulic reversing valve. Olunye lulawulo oluqhubekayo: i-valve port inokuvulwa ngokwesidingo salo naliphi na iqondo lokuvula, ngaloo ndlela ilawula ubungakanani bokuqukuqela, iivalvu ezinjalo zinolawulo lwezandla, olufana ne-throttle valves, kodwa zilawulwa nge-elektroniki, ezifana nokulinganisa. iivalve, iivalve zeservo. Ke injongo yokusebenzisa ivalve elinganayo okanye ivalve ye-servo yile: ukufezekisa ulawulo lokuhamba ngolawulo lwe-elektroniki (ewe, emva kokuba utshintsho lwesakhiwo lunokufikelela kulawulo loxinzelelo, njl.njl.), kuba lulawulo lokuthomalalisa, kufuneka kubekho ukulahleka kwamandla, i-servo. i-valve kunye nezinye iivalve zihluke, ukulahlekelwa kwayo kwamandla kukhulu, kuba idinga ukuhamba okuthile ukuze kugcinwe umsebenzi wesiphaluka sokulawula i-oyile yangaphambili.
Ivalve ye-Electromagnetic (ivalve ye-Electromagnetic) kusetyenziso lwe-electromagnetic

Ivalve elinganayo kunye nokwahlukana kwevalve ye-solenoid

  Ivalve elinganayo luhlobo olutsha lwesixhobo sokulawula amanzi. Kwivalve yoxinzelelo eqhelekileyo, ivelufa yokuqukuqela kunye nevalve eyalathisayo, i-electromagnetic elinganayo isetyenziselwa ukubuyisela indawo yolawulo lokuqala, kwaye uxinzelelo, ukuhamba okanye isalathiso sokuhamba kweoyile ilawulwa ukude ngokuqhubekayo nangokulinganayo. Iivalvu ezilinganayo ngokubanzi zinomsebenzi wembuyekezo yoxinzelelo, kwaye uxinzelelo lwemveliso kunye nesantya sokuhamba asinakuguqulwa ngumthwalo impembelelo yotshintsho.

I-1, ivalve eqhelekileyo ayinakulinganiswa nokulawulwa kwenyathelo eliqhubekayo, ivalve yokutshintsha intshukumo esulungekileyo, indlela yokuvula ivalve, isixa sokuvula okanye ukusetwa kwentwasahlobo amandla aqinisekileyo, ayinakutshintsha ngokwemeko yokwenyani.

I-2, ivalve elinganiselayo ilingana nolawulo lwenyathelo oluqhubekayo, ngokwemeko yokwenyani utshintsho kulwazi oluqokelelweyo umva kwithagethi yolawulo lwembuyekezo oluzenzekelayo, ivalve yokuvula isalathiso, isixa sokuvula okanye ukusetwa kwentwasahlobo amandla alandelwayo, ukuphumeza uthotho lwembuyekezo eqhubekayo. utshintsho olulawulekayo kwisenzo.
