Nhasi, mupepeti achakuudzai kuti mungagadzirisa sei zvikanganiso zvinowanzoitwa pamavharuvhu ekudzora. Ngationei!

Ndezvipi zvikamu zvinofanira kuongororwa kana paine chikanganiso?

1. Rusvingo rwemukati rwemuviri wevharuvhu

Rusvingo rwemukati rwemuviri wevharuvhu runowanzo kanganiswa uye kukanganiswa nechinhu ichi kana mavharuvhu anotonga achishandiswa munzvimbo dzine pressure yakakwira uye dzinopisa, saka zvakakosha kutarisisa kuongorora ngura yaro uye kuramba kwayo kudzvanywa.

2. Chigaro chevharuvhu

Nzvimbo yemukati yeshinda inosunga chigaro chevharuvhu inokurumidza kuora kana vharuvhu inotonga iri kushanda, izvo zvinoita kuti chigaro chevharuvhu chive chakasununguka. Izvi zvinokonzerwa nekupinza kwechinhu chacho. Paunenge uchiongorora, yeuka izvi. Nzvimbo yekuvharira chigaro chevharuvhu inofanira kuongororwa kuti ione kana vharuvhu iri kushanda pasi pekumanikidzwa kwakakosha.

3. Chidimbu

Valvu inotongachikamu chinofambiswa kana chichishanda chinonzivharuvhu yepakatiNdiyo yakanyanya kukuvadzwa nekukuvadzwa nemidziyo yemagetsi. Chikamu chimwe nechimwe chepakati pevharuvhu chinofanira kuongororwa zvakanaka nekuora kwacho panguva yekugadzirisa. Zvinofanira kucherechedzwa kuti kupera kwepakati pevharuvhu (cavitation) kwakanyanya kana musiyano wekumanikidzwa wakanyanya. Zvakakosha kugadzirisa pakati pevharuvhu kana pakakuvara zvakanyanya. Uyezve, unofanira kurangarira chero zviitiko zvakafanana padanda revharuvhu pamwe nechero kubatana kwakasununguka nepakati pevharuvhu.

4. Mhete dze "O" nedzimwe gaskets

Ingava kukwegura kana kutsemuka.

5. Kurongedza kwePTFE, kuisa chisimbiso chemafuta

Ingava kukwegura uye kana nzvimbo yekuberekesa yakakuvara, inofanira kutsiviwa kana zvichidikanwa.

Vharuvhu inotonga inoita ruzha, ndoita sei?

1. Bvisa ruzha rwemanzwi

Simba harizopfuuri kusvika vharuvhu inodzora yarira, zvichiita kuti pave neruzha rukuru runodarika 100 dB. Mamwe ane ruzha rwakaderera asi ane simba guru, mamwe ane ruzha rukuru asi ane simba shoma, nepo mamwe aine ruzha uye ruzha rukuru.

Ruzha rwezwi rimwe chete, runowanzova pamafrequencies ari pakati pe3000 ne7000 Hz, runoburitswa neruzha urwu. Ehe, ruzha urwu ruchapera rwega kana resonance ikabviswa.

2. Bvisa ruzha rwekuvhuvhuta

Chikonzero chikuru cheruzha rwe hydrodynamic i cavitation. Kutenderera kwakasimba kwenzvimbo uye ruzha rwe cavitation zvinokonzerwa nekumhanya kukuru kunoitika kana mabhurumu achidonha panguva ye cavitation.

Ruzha urwu rune huwandu hwakakura hwemafrequency uye ruzha rwekukwenya runofanana nemvura ine matombo nejecha. Imwe nzira inoshanda yekubvisa nekuderedza ruzha ndeyekuderedza nekuderedza kuvhuvhuta kwemuromo.

3. Shandisa mapaipi ane madziro akakora

Imwe nzira yekugadzirisa ruzha ndeyekushandisa mapaipi ane madziro akasimba. Kushandisa mapaipi ane madziro akakora kunogona kuderedza ruzha ne 0 kusvika 20 decibels, nepo mapaipi ane madziro matete kunogona kuwedzera ruzha ne 5 decibels. Kana ruzha rukanyanya, madziro epaipi ane dhayamita imwe chete yepaipi anokora uye dhayamita yepaipi ine ukobvu hwakafanana yemadziro inokura.

Semuenzaniso, huwandu hwekuderedza ruzha hunogona kuva -3.5, -2 (ndiko kuti, yakasimudzwa), 0, 3, uye 6 kana ukobvu hwemadziro epaipi yeDN200 huri 6.25, 6.75, 8, 10, 12.5, 15, 18, 20, uye 21.5mm, zvichiteerana. 12, 13, 14, uye 14.5 dB. Zviri pachena kuti mutengo unowedzera neukobvu hwemadziro.

4. Shandisa zvinhu zvinobata ruzha

Iyi ndiyo nzira inonyanya kufarirwa uye inoshanda yekugadzirisa nzira dzeruzha. Mapaipi anogona kuputirwa nezvinhu zvinotora ruzha kuseri kwemavharuvhu uye manyuko eruzha.

Zvakakosha kuyeuka kuti ruzha runofamba daro refu kuburikidza nekuyerera kwemvura, saka kushandisa mapaipi ane madziro akakora kana kuputira zvinhu zvinobata ruzha hazvizobvisi ruzha zvachose.

Nekuda kwemutengo wayo wakakwira, nzira iyi inonyanya kukodzera mamiriro ezvinhu apo ruzha rwakaderera uye urefu hwemapaipi hupfupi.

5. Muffler yeSeries

Ruzha rwemhepo runogona kubviswa uchishandisa nzira iyi. Rune simba rekuderedza ruzha rwunoendeswa kune yakasimba barrier layer uye kubvisa ruzha rwuri mukati memvura. Nzvimbo dzakakura dzekuyerera kwehuwandu hwemvura kana nzvimbo dzakanyanya kuderera kwesimba remhepo dzisati dzashandiswa uye dzadzinotevera ndidzo dzakakodzera zvakanyanya kuti nzira iyi ive nehupfumi uye ishande zvakanaka.

Zvidziviriri zvinonyudza ruzha zviri mumutsara inzira inoshanda yekuderedza ruzha. Kunyange zvakadaro, kudzikiswa kweruzha kunowanzo ganhurira kusvika pa25 dB nekuda kwemitengo.

6. Bhokisi rinodzivirira ruzha

Shandisa mabhokisi asingapindi ruzha, dzimba nezvivakwa kuti uparadzanise ruzha rwemukati memota uye kuderedza ruzha rwekunze rwenharaunda kusvika padanho rinogamuchirika.

7. Kurova kwemitambo yakatevedzana

Nzira yekukwesha tambo inoshandiswa kana kumanikidzwa kwevharuvhu rinodzora kwakakwira (△P/P1≥0.8). Izvi zvinoreva kuti kudonha kwese kwesimba kunogoverwa pakati pevharuvhu rinodzora nechinhu chinokwesha tambo chakagadzika chiri kumashure kwevharuvhu. Nzira dzakanakisa dzekuderedza ruzha ndeyekushandisa maporous flow limiting plates, diffusers, nezvimwewo.

Chinodimbura chinofanira kugadzirwa zvinoenderana nedhizaini (chimiro chemuviri, saizi) kuti chigone kushanda zvakanaka.
