Uhlalutyo olufutshane lweziphene eziqhelekileyo kunye nemigangatho yovavanyo yokuhlolwa komgangatho wevalve yembonakalo yeTorque ngamandla abangela ukuba into ijike. I-torque ye-injini yitorque ephuma kwi-injini ukusuka ekupheleni kwe-crankshaft. Phantsi kwemeko yamandla angaguqukiyo, ihambelana ngokungafaniyo nesantya senjini. Ukukhawuleza kwesantya, i-torque encinci, kunye ne-torque enkulu, ebonisa umthamo womthwalo wemoto kuluhlu oluthile. Noun explanation: torque Torque ngamandla abangela ukuba into ijike. I-torque ye-injini yitorque ephuma kwi-injini ukusuka ekupheleni kwe-crankshaft. Phantsi kwemeko yamandla angaguqukiyo, ihambelana ngokungafaniyo nesantya senjini. Ukukhawuleza kwesantya, i-torque encinci, kunye ne-torque enkulu, ebonisa umthamo womthwalo wemoto kuluhlu oluthile. Ithini indlela yokubala itorque yevalve? I-valve torque yiparameter ebalulekileyo yevalve, ngoko ke abahlobo abaninzi banenkxalabo malunga nokubalwa kwe-valve torque. Apha ngezantsi, inethiwekhi yevalufa yempompo yempompo yelizwe ukuze ukwazise ukubalwa kwetorque yevalve ngokweenkcukacha. Ukubalwa kwetorque yevalve ngolu hlobo lulandelayo: Isiqingatha sedayamitha yevalve x 3.14 isikwere yindawo yepleyiti yevalve, iphindaphindwe ngoxinzelelo lokuthwala (oko kukuthi, umsebenzi wevalve yoxinzelelo) zoba ishafti kuxinzelelo oluzinzileyo, iphindaphindwe yi-coefficient of friction. (jonga itheyibhile yentsimbi yentsimbi yentsimbi 0.1, intsimbi yerubha friction coefficient 0.15), inani lamaxesha ububanzi be-axle eyahlulwe yi-1000 ye-torque yevalve ekhawulezayo, iyunithi yeenkomo, iimitha, ixabiso lokhuseleko lwereferensi yezixhobo zombane kunye ne-pneumatic ii-actuators ngamaxesha angama-1.5 we-torque yevalve. Xa ivalve iyilwe, ukhetho lwe-actuator luqikelelwa, olwahlulwe ngokwesiseko lwangamacandelo amathathu: 1. I-torque yefriction yezitywina (ingqukuva kunye nesitulo sevalvu) 2. I-torque yefriction yokupakisha kwisiqu sevalvu 3. I-valve stem Ngoko ke, uxinzelelo olubaliweyo ludla ngokuphindaphindiweyo ngamaxesha angama-0.6 (malunga noxinzelelo olusebenzayo), kwaye i-coefficient ye-friction inqunywe ngokwezinto eziphathekayo. I-torque ebalwayo iphindwe ngamaxesha angama-1.3 ~ 1.5 ukukhetha i-actuator. Ubalo lwetorque yevalve kufuneka luthathele ingqalelo ukukhuhlana phakathi kwepleyiti yevalve kunye nesihlalo, ukukhuhlana phakathi kwevalve shaft kunye nokupakishwa, kunye nokutyhala kwepleyiti yevalve phantsi koxinzelelo olwahlukileyo.
