Pampu ya puleesa eya waggulu .
Okwanjula
Pumps za slurry eza puleesa enkulu ze ppampu z’amakolero ezikozesebwa okutambuza ebikuta ebinene, ebikuba ku puleesa enkulu.
Pumps za puleesa eya waggulu (high pressure slurry pumps) zibeera ppampu za centrifugal ezikoleddwa mu ngeri ey’enjawulo okukwata ebiwujjo ebiwunya ebirimu ebikalu ebingi. Zitera okukolebwa mu byuma ebikalu oba omupiira, nga zirina ebiwujjo ebikoleddwa okukwata obutundutundu obunene obugumu. Pampu zino zitera okukozesebwa mu nkola nga ppampu ez’ekinnansi zandiremye okutambuza ebiwujjo mu bbanga eddene.
Okusaba .
Okusima eby’obugagga eby’omu ttaka .
Ekyuma ekifulumya amazzi, okuggya amazzi mu kirombe, payipu z’omukira, okulongoosa eby’obugagga eby’omu ttaka, okujjuza ekirombe
Amafuta ne ggaasi .
Amakolero g’amafuta ne ggaasi era geesigamye nnyo ku ppampu za puleesa eya waggulu. Zikozesebwa mu mirimu gy’okukola fracking, nga ppampu ekozesebwa okufuyira ekikuta kya high-Pressure slurry mu luzzi okukutula olwazi n’okufulumya woyiro oba ggaasi. Era zikozesebwa okutambuza ebitosi ebisima amafuta ne ggaasi, nga bino biba biwunya era nga birimu obutundutundu obugumu.
Eddagala .
Eddagala eritambuza n’ebikalu nga lime slurries, catalyst recovery ne carbon transfer .
Okukola amasannyalaze .
Pampu za puleesa eya waggulu zikozesebwa mu bifo ebikola amasannyalaze okutambuza eddagala ly’amanda. Amanda gasiigibwa ne gafuuka pawuda omulungi ne gatabulirwamu amazzi okukola ekikuta ekipampagibwa mu bboyiyira y’ekyuma ky’amasannyalaze. Pampu ya puleesa eya waggulu yeetaagibwa nnyo mu nkola eno, kuba esobola okukwata ekikuta ekiwunya n’ekinene.
Okulongoosa amazzi amakyafu .
Okukwata ebisasiro, ebisigadde nga bipampagira, ebikuta by’ebimera .
Emigaso emikulu .
Pampu yaffe eya puleesa eya waggulu eriko dizayini y’emu ey’amazzi ey’omunda nga standard-puleeti ya puleesa naye ekkiriza puleesa ezikola ennyo.
Okutereeza mu bujjuvu-Okutereeza mu maaso kumpi tekisoboka mu nkola za waggulu-okunyigiriza. Empeta yaffe ey’okwambala egonjoola kino. Eyanguwa okutereezebwa omukozi omu alina ekisumuluzo eky’omutindo, kisobozesa okufuga okusonseka-okugogola ku ludda, okukuuma omulimu gw’amazzi mu bulamu bwa ppampu ku RPM etakyukakyuka. Kino kivaamu obulungi obw’amaanyi n’obulamu obw’okwambala ebitundu ebigaziyiziddwa.
Ettaayi-okunyweza dizayini ya Millmax ne UMD high-empale esobozesa abakozi okutwala ebipimo by’obuwanvu bwa ultrasonic casing okwetoloola ppampu, okuyamba okulagula n’okuteekawo okuddaabiriza okuggalawo nga okulemererwa tekunnabaawo. Mu kiseera kino, SlurryMax-Pampu za HP zirimu dizayini eyawuddwamu-eyamba okuddaabiriza ebitundu eby'omunda.
Engeri y'okubala omutwe n'okutambula kwa ppampu ya slurry .
A.Slurrry Omutwe gwa Pampu .
Omutwe ge maanyi agafunibwa ppampu ya slurry ey’amazzi ku buli yuniti y’obuzito. Okubala kw’omutwe gwa ppampu ya slurry kwawuddwamu mu mbeera ssatu (nga bwe kiragibwa mu kifaananyi):
Ekika Ekisooka: h-D+S+HF1+HF2+H3+ pd-ps .
Ekika ekyokubiri: h= d-s+hf 1+HF2+HF3+ pd-ps
Ekika eky'okusatu: h= d0p-s+hf1+HF2+HF3+ pd-ps
D--Okufulumya obuwanvu bwa geometry, m; Omuwendo: waggulu okusinga layini y’omu makkati ey’omulyango oguyingira mu ppampu: positiivu; wansi okusinga layini ya wakati ey’omulyango oguyingira mu ppampu: negativu;
S--okusonseka obuwanvu bwa geometry, m; Omuwendo: waggulu okusinga layini y’omu makkati ey’omulyango oguyingira mu ppampu: negativu; wansi okusinga layini ya wakati ey’omulyango oguyingira mu ppampu: positive;
PD, PS--Puleesa ekola mu kibya, M empagi ey’amazzi (puleesa ya gauge); Omuwendo: Okusinziira ku puleesa ya gaagi ennungi n’eya negativu .
HF1--Okufiirwa kwa payipu okugolola, M empagi ey’amazzi;
HF2--PIPE fitting resistance loss, M empagi ey’amazzi;
HF3--Okufiirwa okuziyiza okw’ekitundu n’okufuluma, M empagi ey’amazzi;
H--Omutwe gwa pump, M empagi ey’amazzi.
B.Slurry Pump Omuwendo gw'okukulukuta .
Okusalawo omuwendo gwa slurry pump flow rate okusinga kulina ensonga ssatu zino wammanga:
.
2. Omuwendo gwa bulijjo gwokka ogw’okukulukuta gwe guweebwa mu nkola y’okufulumya, era omugatte ogugere gulina okulowoozebwako.
For large-flow, low-lift slurry pumps with NS>100, omugatte gw’amazzi agakulukuta guli 5%, ku pumps entono-, waggulu-okusitula .<50, the flow margin is 10%, and for pumps with 50≤NS≤100, the flow margin is also 5%. For pumps with poor quality and poor operating conditions, the flow margin should be 10%.
3. Data enkulu egaba obuzito bwokka okutambula, obulina okukyusibwa mu kutambula kwa voliyumu.
