Umbane ojikelezayo we-electromagnetic flowmeterilungele imidiya eqhubayo. Imibhobho yosasazo kufuneka izaliswe ngomlinganiselo wombhobho. Isetyenziswa ikakhulu kugutyulo lwefektri, ugutyulo lwasekhaya, njl.
Masiqale sazi ukuba yintoni ebangele le meko?
Ukuhamba ngoko nangoko kwe-electromagnetic flowmeter ihlala ingu-0, yintoni ingxaki? Indlela yokusombulula ngayo?
1. Umthombo awuhambisi;
2. Kukho ukuhamba kombhobho kodwa awugcwali;
3. Akukho ukuhamba kumbhobho we-electromagnetic flowmeter;
4. I-electrode igqunyiwe kwaye ayidibanisi nolwelo;
5. Ukuhamba kungaphantsi komda ophantsi wokunqunyulwa kwe-flow cut-off ebekwe kwimitha;
6. Ukusetha iparamitha kwiheda yemitha ayichanekanga;
7. Inzwa yonakele.
Ngoku siyazi ukuba yintoni isizathu, sifanele siyiphephe njani le ngxaki ngoku. Xa ukhetha kwaye ufaka ii-flowmeters ze-electromagnetic, kufuneka uqaphele:
1. Okokuqala, iimfuno zomlinganiselo wale yunithi kufuneka zichazwe ngokucacileyo. Kukho iimfuno ezininzi zokulinganisa, ngokukodwa: ukulinganisa okuphakathi, ukuhamba kwe-m3 / h (ubuncinci, indawo yokusebenza, ubuninzi), ubushushu obuphakathi ℃, uxinzelelo oluphakathi lweMPa, ifom yofakelo (uhlobo lwe-flange, uhlobo lwe-Clamp) njalo njalo.
2. Izinto ezifunekayo zokukhetha
i-electromagnetic flowmeter1) Umlinganiselo ophakathi kufuneka ube ngulwelo oluqhubayo (oko kukuthi, ulwelo olulinganisiweyo lufuneka ukuba lube ne-conductivity encinci);
2) Umgangatho ophakathi akufuneki uqulathe i-ferromagnetic medium eninzi kakhulu okanye amaqamza amaninzi.
