Rau cov xaim hluav taws xob, cov xov hlau yog siv los ntawm cov khoom siv tooj liab, vim tooj liab muaj tus nqi qis dua ntawm kev tiv thaiv hluav taws xob tam sim no. Ib qho ntawm ntau hom yog PVAM hlau. Hom xov hlau no yog siv los ua cov khoom siv hauv tsheb.

Cov xov hlau muaj ib qho kev coj ua los ntawm tooj liab thiab muaj ntau cov xov hlau me me sib tw ua ke. Vim muaj ntau cov xov hlau, qhov hloov pauv ntawm cov kab txuas ntxiv thiab qhov tsis kam rau hluav taws xob tam sim no txo. Lub rwb thaiv tsev yog ua los ntawm polyvinyl chloride. Nyob ntawm qhov kev ua haujlwm, nws tau ua nyob rau hauv peb hom:

  • Rau qhov kub thiab txias, qhov rwb thaiv tsev yog ua kom sov-tiv taus, qhov ntsuas kub siab dua me ntsis siab dua qhov ua haujlwm kub.
  • Rau cov ntawv thov uas tsis muaj qhov kub thiab txias, qhov rwb thaiv tsev yog ua kom tiv taus huab cua, thiab thaum lub sij hawm sim, qhov kub thiab txias me ntsis qis dua qhov uas lub cable yuav ua haujlwm.
  • Rau cov xwm txheej nrog nce ntxivQhov kub thiab txias, txhawm rau kom tsis txhob muaj hluav taws kub ntawm cov rwb thaiv tsev, nws tau ua tshwj xeeb rau qhov chaw hluav taws kub thiab cov txheej txheem: hauv nws cov khoom siv, polyvinyl chloride nrog txo cov nplaim taws yog siv. Cov xov hlau zoo li no yog siv los ua cov khoom siv hluav taws xob nyob ze ntawm qhov chaw ntawm cov txheej txheem nrog qhov kub siab.

Rwb thaiv tsev yog pleev xim rau hauv ib lossis ntau xim nyob ntawm cov xwm txheej thiab cov kev xav tau ntawm cov neeg siv khoom. Cov xim tseem ceeb ib txwm nyob ntau dua 50% ntawm cov xim rwb thaiv tsev ntawm PVAM hlau. Cov xim auxiliary yog qee zaum ua los ntawm ntau qhov sib txawv xim kab txaij mus rau ib leeg.

Rau qhov kev ua haujlwm tshwj xeeb, siv lub vijtsam. Qhov no yog qhov yuav tsum tau rau kev sib kis ntawm cov teeb liab pulses txhawm rau txo qhov poob thaum hla PVAM xaim. Ib qho screen yog ua los ntawm nyias tooj liab hlau nyob rau hauv daim ntawv ntawm ib tug braided mesh tinned nrog tin solder. Qee lub sij hawm lub vijtsam yog ua los ntawm cov ntawv ci.

PVAM hlau muaj cov yam ntxwv hauv qab no:

  • ua haujlwm kub li ntawm -40 txog +105 ° C;
  • ntawm qhov kub siab txog 125 ° C, cov xov hlau tuaj yeem tiv taus mus txog 48 teev, thiab ntawm qhov kub ntawm 150 ° C - rau 15 feeb;
  • ntawm qhov kub ntawm +80 ° C, cov xov hlau tsis raug deformation;
  • wires tsis raug deformation thaum khoov, puas, creases, twisting;
  • Lub tsev ntev thaum lub sijhawm tsim khoom tsis pub tshaj 100 m;
  • kev pabcuam lub neej yog txog 8 xyoo, raws li kev ua haujlwm, lub sijhawm lav yog 3 xyoos;
  • ntau tshaj muajKev khiav hauj lwm voltage - 5 kV;
  • tsis cuam tshuam los ntawm ntau yam tshuaj thiab mildew.

Kev txiav txim siab cov cim

Thaum deciphering lub cim ntawm cov khoom siv cable, koj yuav tsum ua tib zoo saib rau daim ntawv xaiv. Rau qhov PVAM hlau no, cov nqi hauv qab no sib haum:

  • P - qhia xaim;
  • B - txhais tau tias nce kev hloov pauv ntawm cov xaim lossis cable;
  • A - txhais tau tias qhov kev nthuav dav ntawm cov hlau no, uas yog, autotractor;
  • M - lub xov tooj no muaj tus neeg xyuas pib.

Thaum kawg ntawm cov tsiaj ntawv qhov tseem ceeb, tus lej ntsuas ntawm txoj kab uas hla ntawm ntu ntawm cov tub ntxhais tooj liab tau qhia. Qee zaum, tom qab tus nqi seem, tus nqi GOST tau qhia, raws li cov hlau tau tsim thiab sim.

PGVA lossis PVAM xov hlau yog tsim los xa hluav taws xob hauv tsheb thiab tsheb laij teb, nrog rau lwm yam kev thauj mus los. Cov hlau no muaj ib qho kev coj ua thiab siv los xa cov hluav taws xob tsawg txog 48 V DC. Lawv siv nyob rau hauv cov cheeb tsam uas muaj qhov kub thiab txias. Ua ntej siv ntawm lub Hoobkas, PVAM xaim raug kuaj raws li kev nyab xeeb thaum lub sijhawm ua haujlwm. Qee lub sij hawm, raws li cov neeg siv khoom xav tau, cov xov hlau no tau tsim los nrog cov txheej txheem tiv thaiv.

hom hlau no yog tsim los rau cov khoom siv hluav taws xob hauv huab cua sov, huab cua sov thiab txias.
