Vharuvhu yeGlobe yePneumatic Actuator Control
✧ Tsananguro
Vharuvhu yekudzora pneumatic inozivikanwawo sevharuvhu yekuchekwa kwepneumatic, imhando yeactuator mu automation system, ine multi-spring pneumatic film actuator kana floating piston actuator uye regulating valve, inogamuchira chiratidzo che regulating instrument, ichidzora kucheka, kubatanidza kana kuchinja mvura iri mu process pipeline. Ine hunhu hwechimiro chiri nyore, mhinduro inonzwisisika uye chiito chakavimbika. Inogona kushandiswa zvakanyanya mumafuta, indasitiri yemakemikari, metallurgy nedzimwe nzvimbo dzekugadzira maindasitiri. Mhepo inobva mupneumatic cut-off valve inoda mhepo yakamanikidzwa yakaseferwa, uye nzira inoyerera nemumuviri wevharuvhu inofanira kunge isina tsvina uye zvidimbu zvemvura negasi.
Sirinda yevharuvhu yepneumatic globe chigadzirwa chakasiyana, chinogona kukamurwa kuita chimwe chete uye kaviri zvichienderana nemaitiro ekuita. Chigadzirwa chinoshanda kamwe chete chine chitubu chesirinda chekugadzirisazve, chine basa rekugadzirisazve otomatiki rekurasikirwa nemhepo, ndiko kuti, kana piston yesirinda (kana diaphragm) iri pasi pekushanda kwechitubu, tsvimbo yekusundidzira yesirinda inodzoserwa kunzvimbo yekutanga yesirinda (nzvimbo yekutanga yekurohwa). Sirinda inobatanidzwa kaviri haina chitubu chekudzoka, uye kufambira mberi nekudzokera kwetsvimbo yekusundidzira kunofanirwa kutsamira panzvimbo yekupinda nekubuda kwemhepo yesirinda. Kana sosi yemhepo ichipinda mukamuri repamusoro repiston, tsvimbo yekusundidzira inofamba ichidzika. Sosi yemhepo ichipinda nepazasi pepiston, tsvimbo yekusundidzira inofamba ichikwira. Nekuti hapana chitubu chekugadzirisazve, sirinda inobatanidzwa kaviri ine simba rakawanda kupfuura sirinda imwe ine dhayamita rimwe chete, asi haina basa rekugadzirisazve otomatiki. Zviri pachena kuti, nzvimbo dzakasiyana dzekupinda dzinoita kuti putter ifambe munzira dzakasiyana. Kana nzvimbo yekupinda kwemhepo iri mugomba rekumashure retsvimbo yekusundidzira, inopinda yemhepo inoita kuti tsvimbo yekusundidzira ifambe, nenzira iyi inonzi sirinda yakanaka. Kusiyana neizvi, kana nzvimbo yekupinda kwemhepo iri parutivi rumwe chete rwetsvimbo yekusundidzira, iyo inopinda yemhepo inoita kuti tsvimbo yekusundidzira idzokere shure, iyo inonzi silinda yekuita. Vharuvhu yepombi yemhepo nekuda kwekuda kukuru kwekurasikirwa nebasa rekudzivirira mhepo, sirinda imwe chete inowanzo shandiswa.

✧ Mabhenefiti eVharuvhu yeGlobe yePneumatic Actuator Control
Munguva yekuvhura nekuvhara vharuvhu yesimbi yakagadzirwa, nekuti kukweshana kuri pakati pedhisiki nepamusoro pekuvhara kwemuviri wevharuvhu kudiki pane kwevharuvhu yegedhi, haipfeki.
Kuvhurika kana kuvharwa kwesimbi yevharuvhu kupfupi, uye ine basa rekucheka rakavimbika, uye nekuda kwekuti shanduko yechigaro chevharuvhu inoenderana nekusvetuka kwedhisiki revharuvhu, yakakodzera kwazvo kugadzirisa mwero wekuyerera. Saka, rudzi urwu rwevharuvhu rwakakodzera zvikuru kuchekwa kana kudzorwa uye kupwanywa.
✧ Basa reKutengesa Mushure meKutengeswa
Senyanzvi yePneumatic Actuator Control Gate Valve uye mutengesi kunze kwenyika, tinovimbisa kupa vatengi basa repamusoro-soro mushure mekutengesa, kusanganisira zvinotevera:
1. Ipai nhungamiro yekushandiswa kwechigadzirwa uye mazano ekugadzirisa.
2. Kana paine kutadza kunokonzerwa nematambudziko emhando yezvigadzirwa, tinovimbisa kupa rutsigiro rwehunyanzvi nekugadzirisa matambudziko munguva pfupi iri kutevera.
3. Kunze kwekukuvadzwa kunokonzerwa nekushandiswa kwakajairika, tinopa mabasa ekugadzirisa nekutsiva mahara.
4. Tinovimbisa kupindura nekukurumidza kune zvinodiwa nevatengi munguva yewarandi yechigadzirwa.
5. Tinopa rubatsiro rwehunyanzvi kwenguva refu, mazano epamhepo uye masevhisi ekudzidzisa. Chinangwa chedu ndechekupa vatengi ruzivo rwakanakisisa rwebasa uye kuita kuti ruzivo rwevatengi ruve nyore uye runonakidza.
