Vanhu vazhinji havasati vambonzwa nezve triethyl aluminium (TEAL), asi inoita basa rakakosha mukugadzirwa kwezvinhu izvo vanhu vanogona kuona nekubata mazuva ese. TEAL ndeye organoaluminium (kabhoni nealuminium) musanganiswa unoshandiswa kugadzira epamusoro-density uye akaderera-density mapurasitiki, rabha, mishonga, semiconductors, uye mapolymers anodiwa pa "doro rine mafuta" mune zvekugezesa uye ma sanitizer emaoko.
Mapolymers anoshanda nekubatanidza mamorekuru ega (kana monomers) mumaketani akakura anogona kushandiswa kugadzira zvigadzirwa. Mune organic polymers, musana wemaketani aya kabhoni uye organometallic makomisheni, akadai seTEAL. Aya makomisheni anopa kabhoni inodiwa pakuita kwepolymerization. Mukugadzirwa kwemamwe mapurasitiki akajairika, musanganiswa weTEAL uye titanium tetrachloride unogona kugadzira Ziegler-Natta catalysts. Iyi ndiyo catalyst inodiwa kutanga kemikari kuita inotungamira kune yakanyanya mutsara olefin polymerization kugadzira polyethylene uye polypropylene.
Chero fekitori inochengeta kana kugadzirisa TEAL inofanirwa kutarisisa kushanduka kwekemikari. TEAL ipyrophoric, zvinoreva kuti ichapisa kana yaiswa mumhepo. Muchokwadi, kuita kwakasimba kwekemikari iyi ine cryogenic liquid okisijeni ndechimwe chezvikonzero zvekushandiswa kwayo seyekutanga nhanho yeroketi igniter yeSpaceX chirongwa. Chinhu chimwe chete chekutaura: kungwarira kwakanyanya kunofanirwa kutorwa kana uchibata chinhu ichi. Kune vagadziri vepurasitiki vanopomba kemikari iyi mazuva ese, mapombi chete akagadzirirwa chirongwa ichi anogona kushandiswa. Kunyanya kutarisirwa kunofanira kutorwa kuti ive nechokwadi chekuti catalyst haina kuratidzwa kumhepo panguva yekugadzirisa.
Pakusarudza pombi yeTEAL maapplication, huchokwadi ndiko kwakakosha zvakanyanya. Imwe neimwe kemikari maitiro anotevera chaiwo formula. Kubaya majekiseni akawandisa kana mashoma makiyi ekushandisa hakuburitse mhedzisiro inodiwa. Mapombi ekuyera anogona kunyatsobaya huwandu hunodiwa hwemakemikari (nekururama kwe +/- 0.5%) ndiyo yekutanga sarudzo yevagadziri vemakemikari maapplication eTEAL.
Nezvekuyerera nekudzvinyirirwa, TEAL inowanzoyerwa nehuwandu husingasviki marita makumi mashanu paawa (gph) uye kudzvanywa kuri pasi pe500 pounds per square inch gauge (psig), iri mukati mehuwandu hwemapombi akawanda emamita. Chikamu chakakosha chepolymerization process ndeyekutevedzera kwakazara neAmerican Petroleum Institute (API) 675 mirau, huchokwadi uye kuvimbika. TEAL inofarira pombi dzinoumbwa ne316 Stainless steel liquid end, 316 LSS ball valve and seat, uye polytetrafluoroethylene (PTFE) diaphragm kuwedzera hupenyu hwekemikari ine ngozi iyi.
Kuchengetedza uye kuvimbika Iyo hydraulically driven diaphragm (HAD) metering pombi inogona kushanda zvakavimbika kwemakumi emakore uye ine nguva yakareba yakareba pakati pekugadzirisa (MTBR). Izvi zvinonyanya kukonzerwa nekugadzirwa kwepombi. Mukati mekuguma kwemvura, vhoriyamu uye kumanikidzwa kwe hydraulic fluid kune rumwe rutivi rwe diaphragm zvakaenzana nekumanikidzwa kwemvura inoshandiswa kune rumwe rutivi, kuitira kuti diaphragm ichengetedze kuenzana kwakaenzana pakati pemvura mbiri. Iyo piston yepombi haina kumbobata diaphragm, inofambisa mafuta ehydraulic mudiaphragm, zvichiita kuti ikotame zvakakwana kuti ifambise huwandu hunodiwa hwemvura inoshandiswa. Iyi dhizaini inobvisa kushushikana pa diaphragm uye ine hupenyu hurefu hwebasa.
Kunyangwe hupenyu hurefu hwakakosha, kukoshesa kunofanirwa kupihwa kune kuvimbika pasina kuvuza. Mapombi ekuyera mashandisirwo eTEAL anofanirwa kuve akashongedzerwa nemavharuvhu ekutarisa kuti aderedze nzira dzinogona kubuda. Iyo yekunze 4-bolt tie tsvimbo inopa yakasimba uye yakavimbika pombi kubatana. Kwenguva yakareba, kudengenyeka kwekunze kwekubatana kwepombi kunogona kukonzera kubuda uye matambudziko makuru epombi.
Iyo PTFE diaphragm ine yakanaka track rekodhi mukupomba TEAL. Mapombi aya anofanirwa kunge aine diaphragm kaviri ine leak yekuona basa, senge pressure geji kana musanganiswa wepressure geji uye chinja kuti uyambire nezvematambudziko anogona kuitika.
Sechikamu chechitatu chekudzivirira, iyo nitrogen gumbeze mu hydraulic casing uye gearbox inodzivirira iyo pyrophoric fluid kubva kumhepo.
Maintenance Ivhavha yekuongorora pa metering pump, iyo inomhanya pa 150 strokes paminiti, mazuva 365 pagore, ichazarura nekuvhara kanopfuura mamiriyoni 70 pagore. Iyo yakajairwa kugadzirisa kana KOP (ramba uchipomba) kit inopa zvikamu zvinodiwa kutsiva pombi yekutarisa vharafu, iyo inosanganisirawo diaphragms, O-mhete uye zvisimbiso. Sechikamu chekuchengetedza kwekudzivirira, inofanirawo kusanganisira kuchinja hydraulic mafuta epombi.
Iko kudiwa kwemapurasitiki emidziyo yekudzivirira yemunhu (PPE), pamwe nemitengo yakaderera yemafuta kudzikisa mutengo wemidziyo, zvinoreva kuwedzera kugadzirwa uye kudiwa kwemameter volatile catalysts (senge TEAL).
