Zvinoshanda Kudzvinyirira uye Kuwedzera Kuwana

Saka, kuparadzwa here? Kwete chaizvo. Dzvinyiriro iri kuuya kubva kumakona akawanda zvino. Haisi vatongi chete; vatengi vemarudzi akawanda vanoda kabhoni data kune yavo Scope 3 emissions. Vanoda kuziva tsoka dzechikamu chese, kusvika kune yekupedzisira washer. Izvi zviri kumanikidza kujeka pasi chetani. Ini ndanga ndiri chikamu cheavo vanotengesa maodhisheni kwaunofanirwa kupa mabhiri ekushandisa, zvitupa zvezvinhu, uye kutambisa marara. Zvinonetsa asi zvinofambisa shanduko.

Kuwana kwacho kunowanzova kuwedzera, kwete kwekuchinja. Ndezvekugadzirisa maitiro aunawo. Zvinhu zvakapfava: kuisa variable frequency drives (VFDs) pane ese pombi uye compressor motors kuti ifanane nemutoro. Kutora tsvina inopisa kubva muchoto kuenda ku pre-heat yekugeza mvura. Kubatanidza mabheji ekuputira kuti awedzere kushandiswa kwetangi uye kuderedza makemikari ekudhonza-kunze. Aya ndiwo asina unsexy, anoshanda tweaks anowedzera. Ivo havagadzirire kuburitswa kukuru kwenhau, asi vanofambisa tsono pasi.

Kutarisa kune webhusaiti yemugadziri, senge zitafasteners.com, unogona kuona zvitupa zvakaita se ISO 14001. Ndiyo hurongwa. Asi muyedzo chaiwo ndiwo unoitika neChipiri masikati kana mutsara wekugadzira uchidzika, uye kukurumidza kugadzirisa kunosanganisira kunzvenga filtration system kuti isangane nenguva yekutumira. Kukanganisa kwezvakatipoteredza kunotungamirirwa munguva idzodzo dzekumanikidzwa, netsika pasi, kwete chete mutemo uri mubhainda.

Pakupedzisira, iyo kwezvakatipoteredza kukanganisa of a drill thread ihuwandu hwechiuru chesarudzo diki. Iri mukusarudza kwesimbi sosi, hurongwa hwekuchengetedza iyo inotonhorera system, tembiricha yekumisikidza pahovhoni yekuomesa, uye nzira yekufambisa yakasarudzwa. Iko hakuna kana bullet rimwe chete resirivheri, ingori basa rakaoma, rinoenderera mberi rekuita imwe neimwe yeidzo sarudzo chidimbu chidiki kukuvadza, uchiri kuita chikamu chinobata nyika pamwechete. Icho ndicho chokwadi chakashata, chisingafadzi pazviri.
