Isiphetho sepompo: yini okufanele ikwazi?

Ipompe ye-auger, ebizwa nangokuthi i-screw, ingenye yezinhlobo zamadivaysi ohlobo lwe-rotary-toothed. Kulo, ikhanda le-liquid ejectedyo lakhiwa ngenxa yokufuduka kwalo ngamapulangwe ajikelezayo ngaphakathi kwe-stator. Kungaba eyodwa noma ngaphezulu, kuye ngokuthi ukucushwa kwedivayisi. Amapompo okugoba atholakala kalula ngamagesi, futhi lokhu kwenziwa ngokukhulisa ukuthambekela kwamazinyo kuwo, nokunciphisa inani lamazinyo kumagesi. Nokho, kungcono ukusebenzisa "inguqulo yokuqala" yedivayisi.

I-screw pump isebenza ngokuhambisana nalesi simiso esilandelayo. Ukuhlanzwa kwamanzi kuyenziwa ngenxa yokuthi ihamba phakathi kwe-screw groove kanye nezindawo zezindlu. I-groove itholakala eceleni kwe-axis yesikulufa. Ngama-protrusions abo "bahamba" ngezindawo eziguqulwayo, okuvimbela uketshezi ukuthi ungabuyeli emuva.

I-screw pump iyasetshenziswa ngokubanzi. Kungasiza ekuqhumeni i-gas, i-steam, kanye nezixube zabo noma iziphuzo ezinezindlela ezihlukahlukene ze-viscosity. Baqala ukukhiqizwa ekude kakhulu ngo-1936. Ngenxa yokuthi kulula ukuklama, bangasebenza ngokukhululekile ngisho nangaphambi kokungcola okuyimishini okunezimpukane ezinamahlumela e-viscous level ezingeni lika-30 MPa. Izici ezinjalo zibaluleke kakhulu ekuxazululeni ubuningi bezinkinga ezihlukahlukene. Ukufakwa okuphelele kwamaphampu okubhebhethekisa okusetshenziselwa umthamo kusetshenziswe ngentshiseko emithonjeni ehloselwe ukukhishwa kwe-methane kusuka emigodini yamalahle, kanye nokupompa amanzi avela lapho. Zisetshenziselwa ukukhipha amafutha, amanzi, kanye neminye imithombo.

I-screw pump inezici zokuklama ezithakazelisayo. Ukwandisa izinga lezimpawu, kanye nokunciphisa inani lokuvuza kulolu hlobo lokuzivumelanisa, kuyisiko ukusebenzisa imizimba yokugaya noma ekhonjiwe. I-screw screw igxiliwe kakhulu entwasahlobo, ngaphezu kwalokho, ukucindezela ketshezi eliphambanwe kudlala indima lapha, okunciphisa kakhulu inani lokuvuza. Amapompi ane-casing ensimbi ayakwazi ukubhekana nemithwalo ephakeme kakhulu kunabalingani babo ababeka ezinzimbeni ezinwebekayo. Idivayisi ene-conical screw ingasebenza kahle futhi ibe yinkinga eqinile.

I-screw pump ejwayelekile kunazo zonke i-pump-three screw pump. Ngokwenzayo, ububanzi balo bububanzi kakhulu. Lokhu kungenxa yezinzuzo ezithile ezithile zalolu hlobo lwemishini:

- ukuhlinzekwa okufana nomzimba;

- kungenzeka ukuthi uphuze izithako ngezihlanganisi eziqinile, ngaphandle kokulimala;

- kungenzeka ukuthi ukuzithokozisa okwenziwe yiziphuzo;

- ingcindezi ephakeme ekutheni ingatholakala ngaphandle kwenqwaba yezigaba zokujova, isici sezinye izinhlobo zamapompo ;

- ngesikhathi sokusebenza, idivayisi idala imiphumela yomsindo ezingeni eliphansi;

- Indlela yokupompa ilinganisela kahle kakhulu.

Lezi zinhlobo nazo zinezimo ezithile, ezingaphansi kakhulu kwezinzuzo:

- izinga eliphakeme ngokwanele lokubunzima ekukhiqizeni lolu hlobo lwemishini, kanye nezindleko eziphakeme;

- Ukungabi nomthetho wevolumu yokusebenza;

- sebenzisa okungenalutho kungamamukeli.
