Ukuphucula ukufuduswa kwempompo yoluhlu lweendlela zokuthenga izakhono zevalvu
Le ndlela yokuphucula i-displacement range ye-screw pump yindlela ethe ngqo, kodwa le ndlela nayo inezithintelo ezithile, iya kwandisa umthwalo wekholomu yentonga, yandise amandla ekholomu yentonga, ukongeza, iya kwenza i-stator, i-rotor. kunye nokunxitywa kwentonga kwi-tubing kwaqina, ngoko ke kunokuthiwa, le ndlela inqunyelwe kwinqanaba elithile. Ngelo xesha, umtya wentonga uyancitshiswa, kodwa xa ukushisa kokukhathala kuphakama kunye nokuxhatshazwa kwe-rubber ye-stator yangaphambili, ukunyuka kwesantya kuya kukhawulelwa kwinqanaba elithile.
Indlela yoku-1: Yandisa isantya seFan Wei
Le ndlela yokuphucula i-displacement range ye-screw pump yindlela ethe ngqo, kodwa le ndlela nayo inezithintelo ezithile, iya kwandisa umthwalo wekholomu yentonga, yandise amandla ekholomu yentonga, ukongeza, iya kwenza i-stator, i-rotor. kunye nokunxitywa kwentonga kwi-tubing kwaqina, ngoko ke kunokuthiwa, le ndlela inqunyelwe kwinqanaba elithile.
Indlela yesibini, ukuphucula iiparameters zesakhiwo (ezifana nokwandisa i-rotor eccentricity, i-stator lead, njl.)
Le ndlela yokuphucula uluhlu lokufuduswa kwempompo ye-screw kukunyusa ukunyanzeliswa kwe-rotor ngokwendlela yokubala yokufuduka kwempompo ye-screw, ukuze kuphunyezwe injongo yokuphucula ukufuduka koluhlu lwepompo ye-screw, kodwa ngokufanayo. , nayo ineziphene, ukwandisa i-eccentricity kuya kukhokelela ekwandiseni kwecandelo le-rotor ububanzi, kodwa nokwandisa imfuno yomthamo wempompo, ukongeza, ngenxa yesithuba esilinganiselweyo equleni, Oku kukwamisela umda wokunyusa impompo. ukufuduswa kweamplitude ngokwandisa i-eccentricity.
Indlela yesithathu, ukwandisa inani leempompo
Le ndlela yindlela esebenzayo ngokwentelekiso yoluhlu oluphezulu lokufuduswa kwempompo, kodwa kwakhona kukho imida.
Indlela yesine, sebenzisa impompo yesikrufu sombane
Nangona ukusetyenziswa kwempompo yokuntywila kombane kunokunyusa kakhulu isantya sokunyusa ukufuduka, kunye nokunciphisa umtya wentonga, kodwa xa ubushushu bokudinwa bunyuka kunye nokumelana nokunxiba kwerabha ye-stator yangaphambili, ukonyuka kwesantya kuya kukhawulelwa kwinto ethile. ububanzi.
Ngokuqhelekileyo, ixabiso lemarike ye-valve kwilizwe lethu lizinzile, nangona kukho ukunyuka okuncinci kunye nokuwa minyaka yonke, kodwa uluhlu luncinci. Iingxaki eziphambili kwiimarike zevalve zimi ngolu hlobo lulandelayo: okokuqala, abanye abaqhubi bathenga iivalve ngaphandle kwegama lefektri kunye nedilesi, ukuprinta inkwenkwezi kunye nesatifikethi somvelisi wokuqala, kubangela ingozi enkulu kwigama lamashishini aqeqeshiweyo. Ngokubanzi, ixabiso lemarike yevalve yelizwe lethu lizinzile, nangona linyuka kwaye liwa minyaka yonke, kodwa uluhlu luncinci. Ezona ngxaki ziphambili kwimarike yevalvu zezi:
Okokuqala, abanye abaqhubi bathenga iivalvu ngaphandle kwegama lomzi-mveliso kunye nedilesi, baprinte inkwenkwezi yomenzi kunye nesatifikethi, nto leyo ebangela umonakalo omkhulu kudumo lwamashishini afanelekileyo.
2. Iivalvu ezihlaziyiweyo. Abanye abaqhubi bathengisa iivalvu ezindala okwesihlandlo sesibini emva kokupeyinta kwakhona, nto leyo ezisa imingcipheko enzulu yokhuseleko kumgangatho weprojekthi.
Ngoko ke, kufuneka kuthathelwe ingqalelo ekukhetheni i-valve efanelekileyo ngenjongo yakho. Ukuphepha ukungaqondakali, ivalve nganye kufuneka icaciswe ngokuchanekileyo. Ngexesha lokubuza okanye umyalelo, iivalve ezifunekayo kufuneka zichazwe ngokufanelekileyo.
Ukukhethwa kobungakanani bevalve kufuneka kumisele ubungakanani begama lombhobho apho ivalve idityaniswe khona. Isixhobo sevalve Le miba ilandelayo kufuneka iqwalaselwe ekumiseleni imathiriyeli yevalvu echanekileyo:
• Isiphakathi solwelo masilawulwe sisivalo
· Uluhlu lweqondo lobushushu lolwelo oluphakathi
· Uluhlu loxinzelelo oluza kulawulwa ivelufa
· Iimeko zemozulu ezinokuchaphazela ukusebenza kwevalvu
· Uxinzelelo olunokwenzeka olungaqhelekanga okanye uxinzelelo apho ivelufa iya kufakwa khona
· Umsebenzi wokulawula iivalvu kufuneka kuhlangatyezwane nazo ngokwemigangatho yokhuseleko okanye iinkqubo zombhobho. Ulwakhiwo lwevalvu nganye yenzelwe ukwenza umsebenzi. Musa ukulindela ivalve enye ukuba yenze yonke imisebenzi yenkqubo yokubhobhoza yonke.
Iqondo loxinzelelo lobushushu. Ukuhlangabezana neemfuno ezisebenzayo, hlawula ingqalelo ekhethekileyo kuxinzelelo - ukulinganisa ubushushu bevalve oyifunayo. Ingqwalasela ekhethekileyo kufuneka ihlawulwe kwizinto zokutywinwa kunye ne-gasketing, eyona nto imisela ubukhulu bexinzelelo-iqondo lokushisa kwe-valve. Cacisa izinto zokutywina kunye nokuhlalisa njengoko kufuneka ukuhlangabezana okanye ngcono kuneemfuno zokwenyani. Iivalvu kunye nokudibanisa. Ukuthembeka kwenkqubo yemibhobho, ukugcinwa kwesiqhelo kwexesha elizayo, izinto zokukhusela ukubola, ukudibanisa kwisiza, ubunzima kunye nokhuseleko zizo zonke izinto ezimele ziqwalaselwe ekunqumeni indlela iivalve ezixhunywe ngayo kwimibhobho.
Imo yokusebenza okanye indlela yokuSebenza Khetha imo yokusebenza efanelekileyo okanye indlela yokusebenza ngokusekwe kuhlobo lwevalvu, ubungakanani, uxinzelelo, ubushushu, kunye nendawo yokufaka. Umyalelo weevalvu
Xa u-odola iivalvu, nceda unike le datha ilandelayo ukuphepha ukuphindaphinda okungeyomfuneko kunye nokulibaziseka ukuqinisekisa ukuba iivalvu ezithengiweyo ngokwenene ziyimfuneko.
1. Idayamitha yevalvu
2. Izinto zokujongana noxinzelelo: izixhobo zokuphosa kunye namacandelo.
3. Iintlobo zevalve: ivalve yesango, ivalve yeglowubhu, ivalve yokukhangela, ivalve yebhabhathane, ivalve yebhola, njl.
4. Imowudi yoqhagamshelwano lwetheminali. Ukuba imodi yokudibanisa imodi ye-welding, ubukhulu bodonga lombhobho wokudibanisa kufuneka bunikezelwe; Ukuba udibaniso luyi-flange, umphezulu we-flange okanye ukugqiba kuya kubonelelwa.
5. Naziphi na izinto ezihluke kwi-standard configuration: izinto zokutywina, izinto zokuzinzisa, i-bolt material, njl.
6. Naziphi na izixhobo: ukukhuselwa kwe-asidi, isixhobo sokutshixa, ukusebenza kwekhonkco, njl.
7. I-Manual okanye i-activators zamandla: Nceda ubandakanye iinkcukacha ezifunekayo zobuchwepheshe.
8. Ukuze kube lula uku-odola, nceda uqinisekise iinkcukacha kunye neemodeli.
