Screw pombi: kuti kunokosha achiziva?

Screw pombi, iyo ichiri kunzi sikuruu, mumwe akasiyana-siyana mano muhombe giya mhando. It Urume kupomba nevezera achiumbwa nokuda kwayo misha sikuruwa rotor kutenderera mukati stator. Pangave rimwe kana kupfuura, zvichienderana mudziyo configuration. Screw pombi zviri nyore kuwana kubva giya, uye izvi zvinoitwa kuwedzera yakatenuka mazino mavari, uyewo kuderedza meno ari rachulis. Zvisinei zviri nani kushandisa "yepakutanga shanduro" ari mudziyo.

The sikuruwa pombi inoshanda maererano zvinotevera pfungwa. Kupomba mvura rinoitwa ne chokwadi kuti chinofamba pakati helical grooves uye hukawanika yacho redzimba. The grooves dziri mumhenderekedzo rotor akabatana. Maberere aro vari "enda" nokuda kuchinjaniswa grooves kuti kudzivisa Urume kufamba shure.

The sikuruwa pombi rinoshandiswa pamusoro zvakanaka siyana. Zvingava runobatsira kupomba gasi, hwemvura uye dzavo wemisanganiswa kana mvura ane zvakasiyana mwero viscosity. Wokutanga kudzipinza kugadzirwa shure muna 1936. Nokuda nyore design, vanogona ushande uye kuvapo nezvishoma kuva viscous zvinwiwa panguva kumanikidza mumatunhu 30 MPa. maitiro aya anokosha kwazvo nokuda Mutongo vakawanda vakasiyana-siyana mabasa. Yose kugadzwa sikuruwa pombi anoshandiswa zvikuru mune matsime aiendeswa kugadzirwa methane kubva marasha vazvo, uyewo kupomba mvura kwazviri. kushandiswa kwavo kugadzirwa mafuta, mvura, uye mamwe matsime.

Screw Pombi ane kunakidza STRUCTURAL zvinhu. Kuwedzera kunaka chisimbiso, uyewo kuderedza uwandu idonhe mu mano urwu zvakajairika kushandisa cylindrical kana conical kwakavharwa nenyama muviri. Conical sikuruwa yokudhinda chitubu chaizvo yakavimbika, mukuwedzera, basa rake reDare kwokudzvinyirira kwomunhu pumped emura, izvo yekudyidzana zvinoderedza uwandu leakage. Pumps kuva muviri simbi, vaikwanisa withstanding yekudyidzana yepamusoro mitoro kupfuura vazvo muNzvimbo kwakavharwa nenyama muviri. A Mudziyo ane tapered sikuruu anogona kushanda zvakanaka pane nyaya yakaoma.

The inonyanya sikuruwa pombi - vatatu-sikuruu. In tsika, ayo kukura kuva zvikuru kwazvo. Izvi imhaka zvimwe zvakanakira yo kwakadai midziyo:

- yunifomu chikafu zvinhu;

- mukana kuti kupomba mvura vane yokuvirisa hwakasimba asina kukuvara;

- mukana kuti kuzvipira priming mvura;

- mukuru kumanikidzwa goho kunogona kuwanikwa pasina vakawanda kupomba mumatanho wakananga kune dzimwe mhando pombi ;

- kana mudziyo pave ruzha migumisiro yakaderera chechetere;

- pombi mashandiro ari pakati nepakati kwazvo.

In ichi mhando, pane matambudziko avowo, izvo zviri zvishoma pane zvazvakanakira:

- munhu zvakakwana yakakwirira mwero kuoma iri kugadzirwa kwaiita midziyo yayo kudhura;

- chisingabviri yokudzora ari kushanda vhoriyamu;

- kushandiswa simbe nyore isingagamuchiriki.
