Ukukhetha uhlobo lwe-Diaphragm Pump

Ⅰ. Uhlobo lomzimba we-valve wempomp ye-diaphragm

Ukukhethwa komzimba we-valve kuyingxenye ebaluleke kakhulu yokukhethwa kwepompo ye-diaphragm. Kunezinhlobo eziningi zezidumbu ze-diaphragm pump valve, ezivame ukusetshenziswa ziqondile ngesihlalo esisodwa, isihlalo esiphindwe kabili, i-engeli, i-diaphragm, ukugeleza okuncane, i-tee, ukujikeleza kwe-eccentric, Uvemvane, i-sleeve, eyindilinga, njll. Izinhlobo eziyi-10.

Ngaphambi kokukhetha i-valve, kuyadingeka ukuhlaziya ngokucophelela okuphakathi, izimo zenqubo kanye namapharamitha wenqubo yokulawula, uqoqa imininingwane eyanele, uqonde izidingo zohleloImpompu, Futhi unqume uhlobo lwe-valve oluzosetshenziswa ngokuya ngemininingwane eqoqiwe.

Ekukhethweni okuthile, izici ezilandelayo zingacatshangelwa:

1. Ukwakheka nokwakheka kwengqikithi ye-valve kubhekwa ikakhulukazi ngokuya ngezici zokugeleza ezikhethiwe namandla angalinganisiwe.

2. Gqoka ukumelana Lapho uketshezi kungukumiswa okuqukethe ukugxila okuphezulu kwezinhlayiya ezibhubhayo, indawo ehlangene ye-valve ne-valve yesihlalo se-valve izophuhlizwa kanzima njalo lapho evaliwe. Ngakho-ke, indlela yokugeleza ye-diaphragm pom valve kufanele ibe bushelelezi, futhi izinto zangaphakathi ze-valve kufanele zibe nzima.

3. Ukumelana nokukhubazeka ngoba okuphakathi kuyakonakala, uma kwenzeka ukwanelisa umsebenzi wokulungiswa, zama ukukhetha i-valve enesakhiwo esilula.

4. Izinga lokushisa nengcindezi ye-medium Lapho izinga lokushisa nengcindezi ye-mediam liphakeme futhi ushintsho lukhulu, isihlalo se-valve nesihlalo se-valve kufanele sikhethwe ngezinguquko ezincane ekushiseni nengcindezi.

5. Vimbela ukuhwamuka kwe-flash nokuhwamuka kwe-Flash nokuhwamuka kwenzeka kuphela kwimidiya engamanzi. Enqubweni yangempela yokukhiqiza, ukuhwamuka kwe-flash kanye ne-cavitation akugcini nje kuphela ukuthinta ukubalwa kwe-coefficient yokugeleza, kepha futhi kwakha ukudlidliza nomsindo, okunciphisa impilo yensizakalo ye-diaphragm pom valve. Ngakho-ke, i-valve kufanele ivinjelwe ekukhanyeni nasekukhetheni lapho kukhetha i-valve.

Ⅱ. Ukukhethwa kwe-diaphragm pump actuator

1. Ukucabangela amandla okukhipha epompo ye-diaphragm

Ngaphandle kohlobo lwe-actuator, amandla okukhipha ayo angamandla asebenzayo asetshenziselwa ukunqoba umthwalo (ikakhulukazi kubhekisa emandleni angalinganisiwe kanye nomzuzu ongalingani kanye nokungqubuzana, ukuvala amandla, amandla adonsela phansi namanye amandla ahlobene)..

Ngakho-ke, ukuze kwenze i-diaphragm pu isebenze ngokujwayelekile, i-actuator ehambisanayo kufanele ikwazi ukukhiqiza amandla okukhipha anele ukunqoba ukumelana okuhlukahlukene, iqinisekisa izinga eliphakeme lokuvala nokuvulwa kwe-valve. Kuma-pneumatic asebenza kabili, ama-hydraulic kanye nogesi, ngokuvamile ayikho intwasahlobo yokubuya.

Ubukhulu bamandla abuhlangene nokuqondisa kwawo okusebenzayo. Ngakho-ke, ukhiye wokukhetha i-actuator ukuthola amandla okukhipha amakhulu kanye ne-torque yemoto.

Okwenza ama-pneumatic actator eyodwa, amandla okukhipha ahlobene nokuvulwa kwe-valve, futhi amandla ephampu le-diaphragm nawo azothinta izici zokunyakaza, ngakho-ke kuyadingeka ukusungula ibhalansi yamandla phezu kwawo wonke uhla lokuvula lwepompo ye-diaphragm.

2. Ukunquma kohlobo lwe-ejensi yokuqalisayo

Ngemuva kokunquma amandla okukhipha we-actuator, khetha i-actuator ehambisanayo ngokwezidingo zemvelo yokusetshenziswa kwenqubo.

Ngezidingo zokugcina ukuqhuma esizeni, kufanele kukhethwe ama-pneumatic actuators, futhi ibhokisi lokuhlangana liwukuqhuma kokuqhuma, futhi ama-actuator kagesi awakhethwa. Uma kungekho imfuneko yokuqhuma, kungasetshenziswa kokubili ama-pneumatic kanye nogesi, kepha ngokombono wokulondoloza amandla, Ama-actuator kagesi kufanele akhethwe ngangokunokwenzeka.

Ama-hydraulic actuators awasetshenziswa kabanzi njengama-pneumatic kanye nogesi, kepha anezici zokunemba kokulungiswa okuphezulu, isenzo esisheshayo nesizinzile. Ngakho-ke, kwezinye izimo, ukuze kufinyelele imiphumela yokulungiswa okungcono, ama-hydraulic actuators kufanele akhethwe. Imishini, efana nokulawulwa kwejubane kwemishini esobala ezitshalweni zamandla, ukulawulwa kwezinga lokushisa nokulawulwa kwama-reactors e-catalytic kuma-foreries kawoyela, njll.
