Chiyambi cha Pulojekiti: Pulojekiti Yochotsa Madzi Ochokera ku Migodi ya ku Mexico

Kampaniyo imagwira ntchito makamaka pokonza miyala ya lead-zinc, zomwe zimapangitsa kuti pakhale matope ambiri a tailings panthawi yopanga. Zipangizo zoyambirira zosefera zinali makina osindikizira ang'onoang'ono oyeretsera mbale ndi chimango okhala ndi malo osefera a 30 sikweya mita imodzi yokha. Inkagwira ntchito yokha, ndipo chinyezi cha keke yosefera chinali chokwera mpaka 28%, zomwe zinapangitsa kuti ndalama zoyendera tailings zikhale zambiri. Pakadali pano, zidazo zinkalephera kugwira ntchito pafupipafupi, ndipo pafupifupi kawiri pa sabata, zomwe zinakhudza kwambiri nthawi yopangira.

Mavuto

• Malo osakwanira osefera omwe sangathe kukwaniritsa zosowa za tsiku ndi tsiku za matani 80 a matope otayira

• Kuchuluka kwa chinyezi cha keke yosefera komwe kumalepheretsa magalimoto onyamula katundu

• Kugwiritsa ntchito bwino kwa mbale zokoka pamanja kuti zitulutse keke, komanso mphamvu yayikulu yogwirira ntchito kwa ogwira ntchito

• Kutayikira kwa zinthu pafupipafupi komanso nthawi yochepa yogwiritsira ntchito nsalu zosefera, zomwe zimapangitsa kuti pakhale ndalama zambiri zosinthira

Yankho

Kasitomala wagula imodzimakina osindikizira a XMZ80/870-30 odziyimira okha, ndi makonzedwe ofunikira aukadaulo otsatirawa:

• Malo osefera ndi 80 sikweya mita, voliyumu ya chipinda ndi malita 1,200 - mphamvu yogwiritsira ntchito imodzi yawonjezeka pafupifupi katatu

• Ma mbale 62 zosefera kuphatikiza mitu iwiri ndi malekezero, kukula kwa mbale 870×870 mm, makulidwe a keke yosefera 30 mm

• Zidutswa 63 za nsalu yosefera ya PP yosalukidwa yokhala ndi kulondola kosefera kwa ma microns 10, zomwe zimachepetsa kwambiri kuchuluka kwa zinthu zolimba mu zosefera

• Kutuluka kwa madzi kudzera m'mabotolo apulasitiki, zomwe zimathandiza kuyang'ana momwe mbale iliyonse imatulutsira madzi m'munda.

• Chokokera cha hydraulic + chokokera mbale chokhachokha kuti keke itulutsidwe yokha

• Dongosolo lowongolera la PLC, lolumikizidwa ndi pampu yodyetsa chakudya ndipo lolumikizidwa ku sensa yokakamiza ya mapaipi - kuthamanga kwa chakudya kumasungidwa bwino pa 0.6 MPa

• Mphamvu ya injini ya siteshoni ya hydraulic 4 kW, m'mimba mwake wa silinda 200 mm, mphamvu yogwira 16–18 MPa, mphamvu yopangira 22 MPa

• Zinthu zotetezera: batani loyimitsa mwadzidzidzi kumbali ya woyendetsa + chingwe chokokera choyimitsa mwadzidzidzi; silinda yokhala ndi gauge ya 0–40 MPa yolumikizira magetsi

Zotsatira za Kukhazikitsa

Kukhazikitsa ndi kukhazikitsa zida kunatenga milungu iwiri. Deta yochokera m'miyezi itatu yoyambirira yogwira ntchito ndi iyi:

Kuphatikiza apo, chifukwa cha chinyezi chochepa cha keke yosefera, galimoto iliyonse yonyamula imatha kunyamula matani ena pafupifupi 3.5 a zinthu zouma paulendo uliwonse, zomwe zimapangitsa kuti ndalama zoyendera pamwezi zichepe ndi 18%. Ndemanga za makasitomala zikusonyeza kuti zidazi zikuyenda bwino, mawonekedwe owongolera a PLC ndi osavuta komanso osavuta kugwiritsa ntchito, ndipo kapangidwe ka chingwe chokokera chadzidzidzi kayamikiridwa kwambiri ndi ogwira ntchito kumunda.
