I roto i te miihini miihini, ko te kowhiringa tika o nga raorao hiko tetahi o nga tikanga taurangi hei whakatutuki i nga whakaritenga whakamahinga. If the electric valve used is not selected properly, it will not only affect the use, but also bring adverse consequences or serious losses, therefore, the correct selection of electric valves in the pipeline engineering design.
E ai ki nga whakaritenga whakahaere hangarau, mo te Vand hiko, ka oti te mahi whakahaere e te taputapu hiko. The purpose of using electric valves is to realize non-manual electrical control or computer control for the opening, closing and adjustment linkage of valves. Ko nga taputapu hiko o tenei ra kaore i te whakamahia noa hei whakaora i te mana. Na te nui o nga rereketanga o te mahi me te kounga o nga hua mai i nga kaihanga rereke, ko te kowhiringa o nga taputapu hiko me te kowhiringa o nga hinu he mea nui ki te kaupapa.
puru kōrere, me utu kia utua ki te kowhiringa o te waahanga whakahaere o te kareti hiko. Hei tauira, kia rite ki nga hiahia o te kaupapa, ahakoa ki te whakamahi i te aratau mana whakahaere, me te aratau whakahaere kotahi, me hono atu ki etahi atu taputapu, he rereke te kaupapa o te whakahaere rorohiko, aha atu. Ko te tauira o te kaiwhakanao taputapu hiko ka whakawhiwhia ki te kaupapa whakahaere hiko hiko, na me whakarite e te Tari Whakamahi te hangarau hangarau me te kaihanga hiko me te whakamaarama i nga whakaritenga hangarau. Hei taapiri, i te wa e whiriwhiri ana koe i tetahi Valves hiko, me whai whakaaro koe ki te hoko i tetahi kaiwhakahaere miihini hiko hiko. Na te mea i roto i te katoa, me hoko motuhake te kaiwhakahaere. I te nuinga o nga keehi, ka whakamahi i te mana kotahi, he mea tika kia hokona he kaiwhakahaere, na te mea he pai ake, he iti ake te hoko i tetahi kaiwhakahaere nui atu i te hoahoa me te hanga i te kaiwhakamahi. Ki te kore e tutuki i te mahinga whakahaere hiko te whakatutuki i nga whakaritenga hoahoa hangarau, me kii te kaiwhakanao ki te whakarereke, ki te tohu tohu ranei.
E rua nga punaha miihini nui mo te whakahaere i te taputapu hiko hiko: kaore tetahi e uru ki te kōpae ka peke me te whakaputa i te taatai; Ko tetahi atu ko te whirihora i tetahi pereti ka hurihia, ka hurihia te Torque putanga ki te whakaputa i te nati stem i roto i te pereti whiu.
If the large stem diameter allowed by the electric device cannot pass through the stem of the equipped valve, it cannot be assembled into an electric valve. Therefore, the inner diameter of the hollow output shaft of the actuator must be larger than the outer diameter of the stem of the open rod valve. Mo te riipene rod pouri i roto i te reiti hurihuri tuwhera me te whiu maha, ahakoa ko te diameter stem me te rahi o te huarahi matua me te nuinga o te waa ka mahi.
Kei roto i nga kaiwhakaari o te Valve a raatau ake whakaritenga motuhake, ara, me kaha ki te tautuhi i te torona, i nga hoia axial ranei. I ngā wā katoapuru kōrereKa whakamahia e nga kaiwhakaari te taapiri i nga papaa. Ka oti te rahi o te taputapu hiko, ka whakatauhia hoki tona tohu mana. Ko te tikanga ka whakahaerehia i te waa kua tohua, kaore e kaha te kaha o te motuka. Heoi, ki te puta nga ahuatanga e whai ake nei, ka arahi pea ki te kohi: Tuatahi, ko te huringa tuku mana he iti, kaore e taea te whiwhi i te miihini e hiahiatia ana, kia mutu ai te motuka; Ko te tuarua ko te mea he whakatika i te ahurewa ki te whakarite i te ahurewa kia nui ake i te taru aukati, ka kaha te riringi nui me te aukati i te motuka; Ko te tuatoru ko te whakamahi i te wa, a ka nui te pikinga wera o te pāmahana o te motuka; Ko te tuawha, ko te huringa o te ahurewa e aukati ana i etahi take, ka nui rawa te tarai; Te tuarima, he tiketike rawa te pāmahana o te pāmahana, e whakaiti ana i te kaha wera o te motuka.
In the past, the method of protecting the motor was to use fuses, overcurrent relays, thermal relays, thermostats, etc., but these methods have their own advantages and disadvantages. Kaore he tikanga whakamarumaru pono mo nga taputapu utaina penei i nga taputapu hiko. Therefore, various combinations must be adopted, which can be summarized into two kinds: one is to judge the increase or decrease of the input current of the motor; Ko te tuarua ko te whakawa i te ahuatanga whakawera o te motuka ano. Ahakoa, ko te huarahi e whai whakaaro ai ki te taha o te mana wera o te motuka.
