Indlela yokukhetha impompo yamanzi
Ukuhamba kwepompo, oko kukuthi, ukuphuma kwamanzi, ngokubanzi akufanelekanga ukukhetha kakhulu, kungenjalo kuya kunyusa iindleko zokuthenga ipompo. Ukuba ikhethwe ngokwemfuno, njengepompo yokuzilungiselela esetyenziswa lusapho lomsebenzisi, ukuhamba kwayo kufuneka kukhethwe kuncinci kangangoko kunokwenzeka; Ukuba umsebenzisi usebenzisa ipompo engaphantsi komhlaba ukunkcenkceshela, kungangcono ukukhetha isantya sokuhamba esikhulu.
1, ukuthenga iimpompo zamanzi ngokweemeko zasekuhlaleni. Kukho iintlobo ezintathu zeempompo zezolimo ezisetyenziswa rhoqo, ezizezi: iimpompo ze-centrifugal, iimpompo ze-axial flow kunye neempompo ze-mixed flow. I-centrifugal pump inentloko ephezulu, kodwa ikhupha amanzi amancinci, efanelekileyo kwiindawo zeentaba nakwiindawo zokunkcenkceshela imithombo. I-axial flow pump inemveliso yamanzi emininzi, kodwa intloko ayiphezulu kakhulu, efanelekileyo ukusetyenziswa kwindawo ethe tyaba. Ukuphuma kwamanzi kunye nentloko yempompo ye-mixed flow ziphakathi kwempompo ye-centrifugal kunye nempompo ye-axial flow, kwaye zifanelekile ukusetyenziswa kwiindawo ezithe tyaba nezineentaba. Abasebenzisi kufuneka bakhethe baze bathenge ngokwemeko yomhlaba, umthombo wamanzi kunye nokuphakama kwamanzi.
2, ukudlula ngokufanelekileyo ukhetho lwepompo yamanzi. Emva kokumisela uhlobo lwepompo, kuyimfuneko ukuqwalasela ukusebenza kwayo ngokwezoqoqosho, kwaye unikele ingqalelo ekhethekileyo ekukhetheni intloko kunye nokuhamba kwepompo kunye namandla ayo axhasayo. Kufuneka kuqatshelwe ukuba kukho umahluko phakathi kwe-lift (total lift) eboniswe kwileyibhile yepompo kunye ne-discharge lift (actual lift) xa isetyenziswa, oku kungenxa yokuba kukho ilahleko ethile yokumelana xa amanzi ehamba ngepayipi yokuhambisa amanzi kwaye kufutshane nombhobho. Ke ngoko, intloko yokwenyani ngokubanzi iphantsi nge-10%-20% kunentloko iyonke, kwaye ukuphuma kwamanzi kuncitshiswa ngokufanayo. Ke ngoko, ekusetyenzisweni kokwenyani, kuphela ngokwesibonakaliso se-80% ~ 90% yentloko kunye noqikelelo lokuhamba, ukhetho lwamandla axhasayo epompo, lunokukhethwa ngokwamandla aboniswe kwisibonakaliso, ukuze ipompo iqale ngokukhawuleza kwaye isebenzise ukhuseleko, amandla enjini angaba makhulu kancinci kunamandla afunekayo epompo, ngokubanzi malunga ne-10% ephezulu kufanelekile; Ukuba kukho umbane, xa uthenga ipompo yamanzi, ungakhetha ipompo ehambelanayo ngokwemandla enjini.
3, ukuthenga ngokungqongqo ipompo. Xa uthenga, kuyimfuneko ukuhlola "izatifikethi ezintathu", oko kukuthi, ilayisenisi yokukhuthaza oomatshini bezolimo, ilayisenisi yemveliso kunye nesatifikethi sokuhlola imveliso, kwaye zizatifikethi ezintathu kuphela ezinokuphepha ukuthengwa kweemveliso ezisusiweyo kunye neemveliso eziphantsi.
Ukukhetha amanani
1, ekusebenzeni okuqhelekileyo kwepompo, ngokubanzi inye kuphela, kuba ipompo enkulu ilingana neepompo ezimbini ezincinci ezisebenza ngaxeshanye, (ngokubhekiselele kwintloko enye kunye nokuhamba), ukusebenza kakuhle kwepompo enkulu kuphezulu kunokwepompo encinci, ngoko ke ngokwembono yokonga amandla, kungcono ukukhetha ipompo enkulu, endaweni yeepompo ezimbini ezincinci, kodwa kwimeko yezi meko zilandelayo, iipompo ezimbini zinokuqwalaselwa ngokubambisana ngaxeshanye: ukuhamba mkhulu, ipompo ayinakufikelela kulo msinga.
2, kwiimpompo ezinkulu ezifuna ukuba nereserve rate ye-50%, iimpompo ezimbini ezincinci zingatshintshwa ukuze zisebenze, ezimbini ezilindileyo (zizonke zine)
3, kwezinye iimpompo ezinkulu, i-70% yeemfuno zokuhamba kwempompo ingasetyenziswa ngexesha elinye, ngaphandle kwempompo eseleyo, ekugcinweni kwempompo, enye impompo isenoxanduva lwe-70% yemveliso yezothutho.
4, kwimpompo efuna iiyure ezingama-24 zokusebenza ngokuqhubekayo, kufuneka kusetyenziswe iimpompo ezintathu, umsebenzi omnye, omnye omiyo, kunye nokugcinwa omnye.
Yahlula phakathi kwenyaniso nobuxoki
Okokuqala, ukupakishwa kwemveliso yepompo yokuqala okanye abavelisi abaxhasayo ngokubanzi kuqheleke ukuba kufane, umbhalo ucacile kwaye uqhelekile, kwaye kukho amagama emveliso aneenkcukacha, iinkcukacha kunye neemodeli, iimpawu zorhwebo ezibhalisiweyo, amagama emizi-mveliso, iidilesi zemizi-mveliso kunye neenombolo zefowuni; Ukupakishwa ngokubanzi kwezixhobo zomgunyathi kurhabaxa, kwaye idilesi kunye negama lemizi-mveliso azicacanga.
Okwesibini, umphezulu wepompo yamanzi ofanelekileyo uthambile kwaye uyasebenza kakuhle. Okukhona iindawo zibaluleke kakhulu, kokukhona ukuchaneka kokusetyenzwa kwazo kuphezulu, kokukhona ukuthintela ukugqwala kokupakishwa kunye nokuthintela ukugqwala. Xa uthenga, ukuba iindawo zifunyenwe zineendawo zokugqwala okanye iindawo zerabha eziqhekekileyo, ukulahleka kokuguquguquka okanye umphezulu wejenali unemigca eqaqambileyo yokusetyenzwa, akufuneki ukuba ibe zezokuqala.
Okwesithathu, ukubonakala kweempompo eziphantsi ngamanye amaxesha kulungile. Nangona kunjalo, ngenxa yenkqubo embi yemveliso, kulula ukuba yonakale, xa uthenga, ubude becala, ikona kunye nezinye iindawo ezifihlakeleyo zezixhobo, ungabona umgangatho wenkqubo yezixhobo.
Okwesine, ezinye iimpompo zizinto ezilahlwayo ezihlaziyiweyo, ngoko ke ukuba nje ipeyinti yomphezulu wezixhobo ingafumaneka emva kwepeyinti endala, kungcono ungayisebenzisi loo mpompo.
Okwesihlanu, iindawo ezithengiweyo zifakelwa emotweni, kuxhomekeke ekubeni ingaba injalo na kwaye inomdibaniso olungileyo wezixhobo. Ngokubanzi, iindawo zokuqala zinokulinganiswa kakuhle kwimoto, kwaye iindawo ezingaphantsi kunzima ukusebenzisana ngenxa yenkqubo embi kunye nempazamo enkulu yokucubungula.
Okwesithandathu, ukuqinisekisa ukuba ubudlelwane bokuhlanganiswa kwepompo buyahlangabezana neemfuno zobugcisa, ezinye iindawo eziqhelekileyo ziqoshwe ngeempawu zokuhlanganiswa ukuqinisekisa ukufakwa ngokuchanekileyo kwezixhobo, ukuba akukho phawu okanye uphawu olungacacanga alunakuchongwa, azizo izixhobo ezifanelekileyo.
Okwesixhenxe, indibano eqhelekileyo yepompo kunye nezinto ezisetyenziswayo kufuneka zihlale zilungile ukuqinisekisa ukuba umthwalo ulula kwaye usebenza kakuhle. Ezinye zeendawo ezincinci kwindibano azikho, kulula ukuqala ukulayisha imoto ukuze kubangele ubunzima, ezo ndawo zinokuba ziindawo zomgunyathi.
Okwesibhozo, ezinye izinto ezibalulekileyo, ingakumbi iklasi yokuhlanganisa, ngokubanzi inemiyalelo, izatifikethi, ukuze kukhokele abasebenzisi ukuba bafake, basebenzise kwaye balondoloze, indibano yobuxoki ngokubanzi ayizukuba nemiyalelo eneenkcukacha zokufakela ezi.
I-Zhuo Meng Shanghai Auto Co., Ltd. izimisele ukuthengisa iinxalenye zeemoto ze-MG&MAUXS kwaye wamkelekile ukuzithenga.
