slurry pump action in national economy mukudziwa?

Pampu ya slurry imatsagana ndi chitukuko cha mafakitale. M'zaka za zana la khumi ndi zisanu ndi zinayi, mtundu wakunja ndi kufananitsa kosiyanasiyana kokwanira pampu yamatope, ndipo yakhala ikugwiritsidwa ntchito kwambiri. Malinga ndi ziwerengero, mu 1880, ambiri zolinga centrifugal slurry mpope linanena bungwe loposa lonse slurry mpope linanena bungwe ndi 90%, pamene chipangizo mphamvu ndi slurry mpope, mankhwala slurry mpope ndi cholinga china chapadera slurry mpope slurry mpope, wanga, chifukwa. 10% yokha ya slurry mpope wa chimbudzi slurry mpope kupanga. Pofika m'chaka cha 1960, pampu ya slurry inali ndi pafupifupi 45% yokha, ndipo mapampu apadera a slurry anali 55%. Malinga ndi zomwe zikuchitika panopa, cholinga chapadera slurry mapampu, kuposa cholinga ambiri slurry mpope kuonjezera chiwerengero cha.

Kumayambiriro kwa zaka za zana la makumi awiri, submersiblepompa madzi ndi United States anapanga woyamba, ntchito m'malo chakuya bwino slurry mpope. Pambuyo pake, maiko aku Western Europe adachitanso kafukufuku ndi chitukuko, ndipo amasintha nthawi zonse, ndikuwongolera pang'onopang'ono. Monga Germany Rhine bulauni malasha, ntchito zosiyanasiyana submersible slurry mapampu oposa 2500 mayunitsi, mphamvu yaikulu mpaka 1600KW, mutu 410m.

Pampu ya submersible slurry m'dziko lathu imapangidwa m'zaka za m'ma makumi asanu ndi anayi mphambu zisanu ndi zinayi, pampu yamadzi yotsekemera kumwera yakhala ikugwiritsidwa ntchito mu ulimi wothirira, ndipo mndandanda wapampopi waung'ono ndi wapakati wapangidwa, ndikuyika kupanga batch. Mphamvu yayikulu komanso pampu yamagetsi yamagetsi yamagetsi yamagetsi, ma motorsible motors adasindikizidwanso, pampu yayikulu ya submersible slurry 500-1200KW yayikidwa pakugwira ntchito pamgodi. Mwachitsanzo, Anshan Steel Corp Yanqianshan Iron ore mine submersible slurry pump ngalande 500KW, nyengo yamvula. Pali zizindikiro kuti, submersible slurry pampu ntchito mgodi kusintha zida ngalande, m'malo lalikulu yopingasa slurry mpope mphamvu. Kuphatikiza apo, pampu ya submersible slurry yokulirapo ndiyopanga zoyeserera.
