Ukuba ugqiba ukufaka ekhawuntarini ngaphakathi indlu umatshini ngeemodyuli RCD enye ibhokisi lweplastiki (HagerGolf, Volta, Vector okanye amandla) okanye yentsimbi mnye ikhaka SCHRN, ngoko ufuna single- okanye ontlantlu-ntathu laliziimitha seemodyuli ndin-kaloliwe (hayi zonke izixhobo kwi komsindo-ngololiwe modularity semvelo). Xa ibhokisi yeplastiki usebenzisa iibholiti ezintathu okanye indibano kaloliwe enguqu imitha lombane. Kwaye yintoni ngcono ukuba imitha igunya phezu ngaphandle kwesakhiwo, umlinganiselo kunye neeyunithi nokukhuselwa? Kuyinto Biz ezifanele, CB-1 H-9, Schur-8. Phambi kokuba idini ukhetho: noba yenza ukuba uthenge sokubala for obandayo kwi din-ngololiwe okanye endaweni ethe tyaba. Kodwa ukuba ukhetha ukufaka din-kaloliwe kukwafuneka ukuba zithengwe. Oko baya kuba ufakelo izixhobo yolinganiso kwi metal isihlangu uhlobo SCHURN okanye SCHRUN.

5. Uthe counter omkhulu izakhono ezahlukeneyo ezongezelelweyo, ezifana izibane, ukubala xa engekho ombane okanye ukusasaza ulwazi kwidispleyi. Noko ke, le misebenzi malunga nokusebenza okanye nocikizeko ifowuni iya kuba nafuthe. They okanye akunjalo, kuxhomekeke kuwe.
6. Ngokupheleleyo konke, ngaphandle kokukhetha, isixhobo phambi kwakho usiya emarikeni, kuxhomekeke zincwadi karhulumente (ukusebenza kunye nokuchaneka) kwi-mveliso. Phezu yokuqinisekisa nempumelelo isixhobo yokundwendwela isitampu, yaye kwimeko - gosplomba. Kwakhona, yokundwendwela kufuneka umhla yongqanianiso, kwaye itywina ngokwawo - Quarter kunye nonyaka lovavanyo. Enye counter kufuneka ivalwe ize ukuseka inkampani amandla mbane kwi isithuba esingadlulanga kwiminyaka emibini, yaye-kwesigaba sesithathu xesha bufinyeziwe ukuya kunyaka omnye. Kwakhona kuyimfuneko ukuhlola ngamaxesha ukuchaneka izibalo yesibali kwaye isebenza. Yiyo loo nto izixhobo ezinjalo kuthiwa-ubude bomtya mezhproverochny ukuba izixhobo zokulinganisa electronic isusela ukusuka kwiminyaka elishumi elinesithandathu, ukususela kumhla kwimveliso.
7. Xa uthenga isixhobo ebala umbane, uze ungalibali ujonge iklasi nokuchaneka. Esi salathisi kukuvumela uyayazi impazamo siphezulu kungavimbela Isibali izibalo. Kwi-avareji, inani Izakhiwo zokuhlala yi-2%.

Kwiinkampani ze mitha engcono

Ngokutsho inkampani amanani Abarcad ezisemthethweni izinze e Moscow, ngowe-2012, ngaphezu kwezigidi ezisibhozo iimitha zombane kwenziwa kummandla we-Russian Federation, apho isabelo yengonyama (90%) babe izixhobo ezi-. Kuthiwa kwinkalo lwasekhaya badla indawo iimitha zombane.

Yeyiphi Kungcono usebenzise? Yinto eyaziwayo ukuba abantu abangaphezu kwama-¾ yonke imveliso eRashiya iwela kwiinkampani ezintathu Russian. Phakathi kwazo kukho inkxalabo "Energomer" (aseStavropol), inkampani "Incotex" (eMoscow) kunye yokulinda "Moscow Plant Instrumentation". Ukukhokela indawo kule trio ithatha "Energomer" nge-40% zemveliso kwi-asethi, kuba ngawo "Incotex" yaye "eMoscow Plant Instrumentation" nge-29 ne-7% ngokulandelelana.
