Namhlanje, umhleli uza kukwazisa indlela yokujongana neempazamo eziqhelekileyo zeevalvu zokulawula. Makhe sijonge!

Zeziphi iindawo ekufuneka zijongwe xa kukho impazamo?

1. Udonga lwangaphakathi lomzimba wevalvu

Udonga lwangaphakathi lomzimba wevalvu ludla ngokuchaphazeleka kwaye lungcoliswe yi-medium xa iivalvu ezilawulayo zisetyenziswa kwiindawo zoxinzelelo oluphezulu kunye ne-corrosive media, ngoko ke kubalulekile ukuqwalasela ukuvavanywa kokungcoliswa kwayo kunye nokumelana kwayo noxinzelelo.

2. Isihlalo sevalvu

Umphezulu ongaphakathi wentambo ekhusela isihlalo sevalvu uyagqwala ngokukhawuleza xa ivalvu elawulayo isebenza, nto leyo ekhokelela ekubeni isihlalo sevalvu sibe buthathaka ngakumbi. Oku kungenxa yokungena kwesixhobo. Xa uhlola, khumbula oku. Umphezulu wokutywina isihlalo sevalvu kufuneka uhlolwe ukuba awubonakali na ngelixa ivalvu isebenza phantsi koxinzelelo olukhulu.

3. I-Spool

Ivalvu yokulawulaicandelo elinokushukuma xa lisebenza libizwa ngokuba yiumongo wevalvu. Yiyo leyo imidiya eyonakeleyo neyonakele kakhulu. Yonke inxalenye yesiseko sevalvu kufuneka ihlolwe ngokufanelekileyo ukuguguleka kwayo kunye nokugqwala kwayo ngexesha lokugcinwa. Kufuneka kuqatshelwe ukuba ukuguguleka kwesiseko sevalvu (i-cavitation) kuba nzima ngakumbi xa umahluko woxinzelelo umkhulu. Kubalulekile ukulungisa isiseko sevalvu ukuba sonakele kakhulu. Ngaphezu koko, kufuneka uqaphele naziphi na iziganeko ezifanayo kwisiqu sevalvu kunye naluphi na uqhagamshelo olukhululekileyo nesiseko sevalvu.

4. Iindandatho ze-“O” kunye nezinye ii-gaskets

Nokuba kukwaluphala okanye kukuqhekeka.

5. Ukupakisha i-PTFE, ukutywina igrisi

Nokuba iyaluphala kwaye nokuba umphezulu wokudibana wonakele, kufuneka itshintshwe ukuba kuyimfuneko.

Ivalvu elawulayo yenza ingxolo, ndingenza ntoni?

1. Susa ingxolo yesandi

Amandla awayi kufakwa ngaphezulu de ivalvu elawulayo ivakala, idale ingxolo enkulu engaphezulu kwe-100 dB. Ezinye zinengxolo ephantsi kodwa zinamandla, ezinye zinengxolo enkulu kodwa zibuthathaka, ngelixa ezinye zinengxolo kunye nokungcangcazela okukhulu.

Izandi zethoni enye, ezidla ngokuba phakathi kwamaza aphakathi kwe-3000 kunye ne-7000 Hz, ziveliswa yile ngxolo. Kakade ke, ingxolo iya kuziphelela ukuba isandi siyasuswa.

2. Susa ingxolo yokucaphuka kwesisu

Eyona nto iphambili ebangela ingxolo ye-hydrodynamic yi-cavitation. Ingxolo enamandla yendawo kunye ne-cavitation iveliswa yimpembelelo yesantya esiphezulu eyenzeka xa amaqamza ewa ngexesha le-cavitation.

Le ngxolo inoluhlu olubanzi lwee-frequency kunye nesandi sokurhawuzelela esikhumbuza ulwelo oluqulethe iingqalutye kunye nesanti. Enye indlela esebenzayo yokususa nokunciphisa ingxolo kukunciphisa nokunciphisa ukurhawuzelela.

3. Sebenzisa imibhobho enodonga oluqinileyo

Enye indlela yokujongana nendlela yesandi kukusebenzisa imibhobho eneendonga ezomeleleyo. Ukusetyenziswa kwemibhobho eneendonga ezixineneyo kunokunciphisa ingxolo nge-0 ukuya kwi-20 decibels, ngelixa imibhobho eneendonga ezixineneyo inokunyusa ingxolo nge-5 decibels. Okukhona isiphumo sokunciphisa ingxolo siqina, kokukhona udonga lombhobho olunobubanzi obufanayo bombhobho luba lukhuni kwaye ububanzi bombhobho obufanayo bobukhulu bodonga bube bukhulu.

Umzekelo, ubungakanani bokunciphisa ingxolo bungaba yi--3.5, -2 (oko kukuthi, iphakanyisiwe), 0, 3, kunye no-6 xa ubukhulu bodonga lombhobho we-DN200 buyi-6.25, 6.75, 8, 10, 12.5, 15, 18, 20, kunye ne-21.5mm, ngokulandelelana. 12, 13, 14, kunye ne-14.5 dB. Ngokwemvelo, ixabiso liyakhula ngobukhulu bodonga.

4. Sebenzisa izixhobo ezitsala isandi

Le yindlela edumileyo nesebenzayo yokucubungula iindlela zesandi. Iipayipi zinokusongwa ngezinto ezifunxa isandi ngasemva kweevalvu kunye nemithombo yesandi.

Kubalulekile ukukhumbula ukuba ingxolo ihamba umgama omde ngokuhamba kolwelo, ngoko ke ukusebenzisa imibhobho enodonga oluqinileyo okanye ukusonga izinto ezifunxa isandi akuyi kuyisusa ngokupheleleyo ingxolo.

Ngenxa yexabiso layo eliphezulu, le ndlela ifanelekile kakhulu kwiimeko apho amanqanaba engxolo ephantsi kwaye ubude bemibhobho bufutshane.

5. Isixhobo sokuvala uthotho

Ingxolo ye-aerodynamic ingasuswa kusetyenziswa le ndlela. Inamandla okunciphisa ngokufanelekileyo ingxolo edluliselwa kumaleko othintelo oluqinileyo kwaye isuse ingxolo engaphakathi kolwelo. Iindawo ezinkulu zokuhamba kobunzima okanye umlinganiselo wokuhla koxinzelelo oluphezulu ngaphambi nasemva kwevalvu zilungele kakhulu ukonga nokusebenza kakuhle kwale ndlela.

Izithulisi ezifunxayo ziyindlela esebenzayo yokunciphisa ingxolo. Nangona kunjalo, ukuncitshiswa kwengxolo kudla ngokukhawulelwa kwi-25 dB ngenxa yeendleko.

6. Ibhokisi engangeni ngxolo

Sebenzisa iibhokisi ezingangeni ngxolo, izindlu kunye nezakhiwo ukuze wahlukanise imithombo yengxolo yangaphakathi kwaye unciphise ingxolo yangaphandle yokusingqongileyo ukuya kuluhlu olwamkelekileyo.

7. Ukuqhobosha kothotho

Indlela yokuthontelana ngochungechunge isetyenziswa xa uxinzelelo lwevalvu elawulayo luphezulu (△P/P1≥0.8). Oku kuthetha ukuba lonke uhla loxinzelelo lusasazwa phakathi kwevalvu elawulayo kunye ne-fixed throttling element engasemva kwevalvu. Iindlela ezilungileyo zokunciphisa ingxolo kukusebenzisa iipleyiti ezithintela ukuhamba kwamanzi ezinemingxuma, ii-diffusers, njl.

I-diffuser kufuneka iyilwe ngokwendlela eyilwe ngayo (imilo ebonakalayo, ubungakanani) ukuze i-diffuser isebenze kakuhle.
