Zu — h Taxanaha Shaandhaynta Khadka Cadaadiska Sare ee Qu-h
Superheater -ka waxaa lagu rakibay xariijinta cadaadiska ee nidaamka hawo -mareenka si uu uga daadiyo wasakhda, garoonka, haraaga kaarboonka, iwm laga bilaabo wasakhda farsamada iyo falcelinta kiimikada ee saliidda hidde -sidaha lafteeda, sidaas darteedna looga hortago in ay ku dhegto dhegta daloolinta daloolka daloolka iyo qaybaha hydraulic -ga oo aad u xira, iyo guuldarooyin kale. Shaandhayntu waxay leedahay saamayn shaandhayn oo wanaagsan iyo saxnaan sare, laakiin way adag tahay in la nadiifiyo ka dib marka la xanibay, oo xudunta heerkulka waa in la beddelaa. Qalabka daadinta waxaa lagu qalabeeyay qalab dirista farqiga cadaadiska. Marka xudunta dillaaca lagu xiro farqiga cadaadiska ee soo -galinta saliidda iyo soo -bixintu waa 0.35 MPA, waxaa la soo dirayaa signal -beddelka, oo xuddunta heerkulka ayaa la beddelaa waqtigan si loo gaaro himilada ilaalinta badbaadada nidaamka. Xaqiijinta heerkulka oo aad u sarreeya ayaa lagu habeeyay si hufan oo heerkulku aad u sarreeyo iyo saamiga hoos-u-dhaca ee 03,5,10,20 & GT 200, wax-ku-oolnimada xad-dhaafka i1n99.5%, si waafaqsan heerka ISO.
Miirayaasha taxanaha ZU-Hx QU-H waa nooc cadaadis sare leh waxaana loo adeegsadaa khadka cadaadiska ee nidaamka hydraulic. Qaybta shaandhaynta waxaa laga sameeyaa fiber galaas ama warqad. Tilmaamaha cadaadiska kala duwan ayaa tilmaamaya marka cadaadiska hoos uga dhaco walxaha shaandhaynta uu gaaro 0.35MPa.

Note: 10L/min connecting thread M18 x 1.5, 25L/min connecting thread M22 x 1.5 is special order. The model will be ZUT-H10 x *P and ZUT-H25 x *P.
Change instructions
① The original flow rate of 10l/min is 10l/min, except the screw size of the oil inlet and outlet is changed from 2-M18XL5 to 2-M27x2(model Zu-h10x * P) , the other size is the same, 2-M18X1.5 is special, order, model is Zut10x * P, 2-M27 x 2(model ZU-H25 x * P) is changed from 2-M22 x l 5 to 2-M27 x 2(model ZU-H25 x * P) , the other size, unchanged, 2-M22 XL5 is a special order, model zut-h25 x * P, the above changes will take effect from January 1,1986.
② The CS-V differential pressure transmitter in the original sample has been changed from s to P and is a CMS differential pressure transmitter. The CMS differential pressure transmitter is based on the CS-V differential pressure transmitter, it is a more advanced and reliable anti-signal device with visual observation and electric transmission.
