Ho leka-lekanya mabili le libolo (granules, phofo): moelelo, melemo le boiketlo, maikutlo
Tse ka hare
Ho leka-lekanya mabili ka li-granules ke mokhoa o mocha oa ho leka-lekanya lintlha tse boima tsa lithaere ka li-microbead tse khethehileng ntle le tšebeliso ea litulo kapa boima. Ka lebaka la mokhoa ona, hoa khoneha ho lelefatsa bophelo ba thaere le ho fokotsa mojaro likarolong tsa ho tsamaisa.
Ho leka-lekanya mabili a nang le granules ho u lumella ho leka-lekanya likarolo tsohle tse potolohang tsa thaere ha koloi e ntse e tsamaea. Ka lebaka la phetoho ena, mojaro oa chassis, tšebeliso ea mafura le ho roala ha mabili a fokotsehile.
Li-granules tse leka-lekaneng ke eng
Tsena ke li-propants tse nyenyane, tse bōpehileng joaloka chitja tse nang le sheath ea silicone. Li-cores tsa tsona li entsoe ka thepa ea refractory. Bophara ba libolo tsa mabili bo tsoa ho 0,15-2 mm. Li na le sebopeho se thata (7 ho tse 10 ka tekanyo ea Mohs) le porosity e ka tlaase ho 0,3%. Ntho e ikhethang ea sebopeho sena e tiisa ho senyeha ho fokolang ha li-granules le bophelo bo bolelele ba tšebeletso.
Ho leka-lekanya mabili a koloi, ho sebelisoa phofo e entsoeng ka likhalase le lirafshoa. Phetolelo ea pele ea propant e na le ho hanyetsa metsi a fokolang.
Ho leka-lekanya mabili le libolo (granules): moelelo oa mokhoa
Lifaha li tlatsa ka hare ho k'hamera ea koloi. Nakong ea leeto, libolo li phalla 'me li ajoa ka ho lekana holim'a lebili ka lebaka la ketso ea matla a centrifugal. Ka lebaka la khohlano khahlanong le lebota, li-microbeads li bokella tjhaja ea electrostatic ebe li khomarelana libakeng tse nang le moroalo o mongata, ho lokisa ho se leka-lekane ha thaere.
Ha mochine o emisa, proppant e tla boloka boemo ba eona. Haeba lebili le kena ka mokoting, mokoting kapa tšitiso leha e le efe ka lebelo, libolo li tla phunya. E le hore ba ka leka-lekanya lebili hape, mokhanni o lokela ho potlakisa koloi sebakeng se bataletseng ho 30-50 km / h.
Libolo tse leka-lekaneng
Hape, ha koloi e ntse e tsamaea, li-granules li leka-lekanya brake disc le hub ka boikemelo. Li-node tsena li thata ho lekanya mochine kapa ka thuso ea boima.
Melemo le melemo ea mokhoa ona, litlhaloso tsa beng ba likoloi
Ho leka-lekanya mabili ka libolo ho tla u thusa ho rarolla mathata a mangata a ho emisoa le ho tsamaisa kapele ntle le ho ikopanya le setsi sa litšebeletso.
Melemo ea mantlha ea mokhoa oa tokiso ea microballoon:
- e tlosa ho thothomela le ho kokota, "ho lelera" ho se leka-lekane ka lehlakoreng le ka pele;
- ho itekanya thaere ha litšila, majoe, lehloa le hatakelong li khoptjoa 'me li theoha;
- e tiisa mojaro o tšoanang holim'a rabara;
- e ntlafatsa ho tšoara patch ea ho kopana le ho fana ka ho khanna ha bonolo litseleng tse mpe;
- e eketsa botsitso ba koloi ha e koaleha;
- e fokotsa tšebeliso ea mafura ka 10%;
- e sebetsa ho fihlela thaere e fela ka ho feletseng.
Mathata a mokhoa ona:
- ho leka-lekanya boima ba mabili a itekanetseng ho sebetsa feela karolong e bataletseng ea pina ka lebelo le tsitsitseng ho fihlela ho 50 km / h;
- ha mosireletsi a robeha kapa a theoha, li-microbeads li fofa ka thōko;
- ka lebaka la boholo bo nyane ba libolo, ho thata ho e bokella ntle le mochini o hloekisang;
- ha u otla tšitiso kapa sekoti, li-granules lia oa 'me ho hlokahala hore ho lokisoe bocha;
- boima bo feteletseng ba phofo ea lifaha (ho tloha ho 70-500 g).
Maikutlo mabapi le ho leka-lekanya mabili le libolo bakeng sa likoloi tsa Marang-rang lia hanyetsana. Basebelisi ba bangata ba belaella melemo ea li-granules, ha ba bang, ho fapana le hoo, ba hatisa melemo ea lifaha.
Maikutlo mabapi le ho leka-lekanya mabili le libolo
Hangata, maikutlo le maikutlo a video a hlaha a le ntle. Ka mohlala, mong'a koloi ea 1 o ngola hore ka mor'a ho kenya mekotla, mabili a ne a lokisoa hantle ho latela boima ba 'mele. Ha o otla leqhubu ka lebelo la 100 km / h, ho ile ha hlaha ho otla ka lebili la setereng. Ho felisa sekoli, lebelo le ne le lokela ho fokotsoa ka metsotsoana e 10.
Ho leka-lekanya le granules - tlhahlobo
Mokhoa oa ho leka-lekanya mabili
Ho leka-lekanya boima ba likarolo tsohle tsa lithaere ho sebelisa microgranules ho ka etsoa ka litsela tse peli:
- ka ho kenya mokotla o nang le perforated holim'a disk;
- ho pompa difaha phaposing ka ho sebedisa sekepe.
Tabeng ea pele, sephutheloana se kenngoa ka har'a thaere. Nakong e tlang, ha lebili le potoloha, mokotla o tabohile haufi le seame, 'me li-granules li aroloa ka ho lekana ho pholletsa le kamore.
Li-granules tse lekanyang lebili
Khethong ea bobeli, ha ho hlokahale hore u tlose lithaere. Libalune tse nyenyane li kena ka har'a balune li sebelisa mochine o ntšang moea kapa botlolo ea polasetiki e nang le hose. U tla hloka ho qhaqha thaere ea thaere ebe o ntša moea. Ebe o kenya tube ka har'a valve ebe o pompa li-granules ka kamoreng.
E lekana le mabili afe?
Theknoloji ea ho leka-lekanya li-granules qalong e ile ea ntlafatsoa bakeng sa ho tsamaisa thepa. Li na le bophara bo boholo ba mabili, ho sisinyeha ho matla le ho thothomela ho chassis ho tsoa ho phello ea matla a centrifugal ka lebili. Ka hona, phello ea li-microbead calibration e tla bonahala haholo lithaereng tsa literaka ho feta lithaereng tsa koloi kapa tsa sethuthuthu.
Ho leka-lekanya mabili ka li-granules ke mokhoa o mocha oa ho leka-lekanya lintlha tse boima tsa lithaere ka li-microbead tse khethehileng ntle le tšebeliso ea litulo kapa boima. Ka lebaka la mokhoa ona, hoa khoneha ho lelefatsa bophelo ba thaere le ho fokotsa mojaro likarolong tsa ho tsamaisa.
