Nhasi, mupepeti achasuma kwauri maitiro ekuita nezvikanganiso zvakajairika zvekudzora mavharuvhu.Ngatitarisei!

Ndezvipi zvikamu zvinofanira kuongororwa kana chikanganiso chikaitika?

1. Rusvingo rwemukati rwemuviri wevharuvhu

Rusvingo rwemukati rwemuviri wevharuvhu runowanzo kukanganiswa uye kusvibiswa nepakati kana mavharuvhu ekudzora anoshandiswa mu-high-pressure differential uye corrosive media settings, saka zvakakosha kutarisisa kuongorora corrosion yayo uye pressure resistance.

2. Chigaro chevhavha

Nzvimbo yemukati yeshinda inochengetedza chigaro chevharuvhu inodya ngura nekukurumidza kana vharuvhu iri kushanda, izvo zvinoita kuti chigaro chevharuvhu chiregere.Izvi zvinokonzerwa nekupinda kwesvikiro.Paunenge uchiongorora, ramba uchifunga izvi.Ivhavha yechigaro chekuisa chisimbiso chepamusoro inoda kuongororwa kuti iparare apo valve iri kushanda pasi pekumanikidzika kwakasiyana-siyana.

3. Spool

The regulating valve'schinofambiswa kana chiri kushanda chinonzi thevharafu core.Ndiyo iyo nhepfenyuro yakakuvadza uye yakaparadza zvakanyanya.Chese chikamu chepakati chevhavha chinoda kuve nekupfeka kwayo uye corrosion iongororwe zvakanaka panguva yekugadzirisa.Izvo zvinofanirwa kucherechedzwa kuti kupfeka kweiyo valve core (cavitation) yakanyanya kuoma kana kudzvinyirirwa kwakasiyana kwakakura.Izvo zvinodiwa kugadzirisa chivharo chevhavha kana chakanyanya kukuvadzwa.Uyezve, iwe unofanirwa kurangarira chero zviitiko zvinofananidzwa pahunde yevharuvhu pamwe nechero hukama hwakasununguka nepakati pevhavha.

4. "O" zvindori uye mamwe magaskets

Kungave kuchembera kana kutsemuka.

5. PTFE kurongedza, kuisa chisimbiso girisi

Ingave kuchembera uye kana nzvimbo yekubatanidza yakakuvadzwa, inofanira kutsiviwa kana zvichidikanwa.

Ivhavha inogadzirisa inoita ruzha, chii chandinofanira kuita?

1. Bvisa resonance noise

Simba racho haringafukidzwe kusvika vharafu inodzora yarira, ichigadzira ruzha rukuru rwunopfuura 100 dB.Mamwe ane ruzha rwakaderera asi mavibrations ane simba, mamwe ane ruzha asi asina kusimba, asi mamwe aine ruzha uye mavibrations makuru.

Ruzha rwezwi rimwechete, kazhinji pamafrequency ari pakati pe3000 ne7000 Hz, anogadzirwa neruzha urwu.Zvechokwadi, ruzha runobva rwaenda rwoga kana resonance yabviswa.

2. Bvisa cavitation ruzha

Chikonzero chikuru che hydrodynamic ruzha ndeye cavitation.Kushungurudzika kwakasimba kwenzvimbo uye ruzha rwecavitation runogadzirwa nehupamhi hwepamusoro-soro hunoitika apo mabhubhu anodonha panguva ye cavitation.

Ruzha urwu rune ruzha rwakafara uye ruzha runoita senge mvura ine hurungudo nejecha.Imwe nzira inoshanda yekubvisa uye kuderedza ruzha ndeyekudzikisa uye kuderedza cavitation.

3. Shandisa mapaipi ane madziro akakora

Imwe sarudzo yekugadzirisa nzira yekurira ndeye kushandisa mapaipi ane madziro akasimba.Kushandiswa kwepombi dzakakobvu nemadziro kunogona kuderedza ruzha ne0 kusvika ku20 decibel, nepo mapaipi ane madziro matete anogona kuwedzera ruzha nemadecibel mashanu.Kusimba kwekuderedza ruzha, ndiko kuwedzera kwemudhuri wepombi yedhayamita imwe yepombi uye kukura kwepaipi dhayamita yehukobvu hwakafanana.

Semuenzaniso, huwandu hwekudzikisa ruzha hunogona kuva -3.5, -2 (kureva, kusimudzwa), 0, 3, uye 6 apo ukobvu hwemadziro eDN200 pombi iri 6.25, 6.75, 8, 10, 12.5, 15, 18, 20 , uye 21.5mm, zvichiteerana.12, 13, 14, uye 14.5 dB.Sezvingatarisirwa, mutengo unowedzera nehupamhi hwemadziro.

4. Shandisa zvinhu zvinobata inzwi

Iyi zvakare ndiyo inonyanya kufarirwa uye inoshanda nzira yekugadzira nzira dzekurira.Mapombi anogona kuputirwa nezvinhu zvinotora ruzha kuseri kwemavharuvhu uye kunobva ruzha.

Zvakakosha kuyeuka kuti ruzha runofamba madaro marefu kuburikidza nekuyerera kwemvura, nekudaro kushandisa mapaipi ane madziro akakora kana kuputira zvinhu zvinobata ruzha hazvizopedze ruzha rwacho zvachose.

Nekuda kwekudhura kwayo, nzira iyi yakanyatsokodzera zviitiko umo ruzha rwakadzikira uye hurefu hwepombi hupfupi.

5.Series muffler

Aerodynamic ruzha runogona kubviswa uchishandisa nzira iyi.Iyo inokwanisa kunyatso kudzika nhanho yeruzha inotaurirwa kune yakasimba barriers layer uye kubvisa ruzha mukati memvura.Kuyerera kwehuremu hombe kana kudonha kwereshiyo kwakakwira nzvimbo isati yasvika uye nekutevera vharafu ndiyo inonyanya kukodzera hupfumi hweiyi nzira uye kushanda kwayo.

Absorptive in-line silencers inzira inoshanda yekucheka ruzha.Zvakangodaro, iyo attenuation inowanzo kuganhurirwa kune ingangoita 25 dB nekuda kwemitengo yezvinhu.

6. Bhokisi rinodzivirira inzwi

Shandisa mabhokisi asina ruzha, dzimba uye zvivakwa kupatsanura mukati ruzha masosi uye kuderedza kunze ruzha rwemhoteredzo kusvika kune inogamuchirwa.

7. Series throttling

Iyo yakatevedzana throttling nzira inoshandiswa kana dhizaini yevhavha yekudzora yakakwira (△P/P1≥0.8).Izvi zvinoreva kuti kudonhedzwa kwese kwesimba kunogoverwa pakati pevhavha inogadzirisa uye yakagadziriswa throttling element kuseri kwevhavha.Nzira dzakanakisa dzekudzikisa ruzha dziri kuburikidza ne porous kuyerera kudzikamisa mahwendefa, diffuser, nezvimwe.

Iyo diffuser inofanirwa kugadzirwa inoenderana nedhizaini (chimiro chemuviri, saizi) kuitira yakanyanya diffuser kunyatsoita.
