Mpira mavavu - Zosiyanasiyana atenthe Crane

Zina zipangizo chitsekere wolemera zigwire mavavu mpira, popanda zomwe n'zosatheka kulingalira mapaipi, ntchito Ndikuuzani gaseous ndi madzi mafuta, gasi, madzi ndi madzi mafakitale, alkalis ndi zidulo kumwa. Crane palokha ndi mtundu wa mavavu payipi, yodziwika ndi zinthu opaleshoni ya mawonekedwe ozungulira. Chotero kapangidwe njira si zachilendo, ndipo lakhala likugwiritsidwa ntchito kwa zaka zambiri, koma mavavu zosiyanasiyana wakhala atangomwalira kukhala moona cholimba ndi odalirika.

Tsopano nthawi kupanga kuli nthambi mpira akhala akugwiritsidwa ntchito zomangira kopitilira muyeso monga PTFE ndi mphira kupanga. N'zotheka kwambiri wosalira kamangidwe ka mavavu payipi ndipo kwambiri zokulitsa ntchito zipangizozi. Monga mpira vavu shutter mutuluka zitsulo mpira ndi olamulira umadutsa dzenje kudzera amene ntchito madzimadzi adutse. Mu zinthu pamene m'mimba mwake wa mabowo wofanana ndi awiri a mkati mwa payipi imatchedwa zonse zinabala valavu. Ngati ndi zochepa, Kireni imatchedwa nepolnoprohodnym.

Kawirikawiri wathandizidwa ndi mu chishalo, amene tichipeza PTFE washers moyandikana mwachilungamo zolimba, koma chipangizo kasamalidwe amatipatsa mphamvu zochepa. Pakuti mpira vavu yodziwika ndi maudindo awiri kwambiri ndiponso kusintha chipata udindo chifukwa kasinthasintha cholembera wapadera. Pankhaniyi, mavavu mpira angagwiritsidwe ntchito ngati kulamulira ndi amphamvu mavavu payipi chitsekere kwambiri. Pakati mpira mavavu angasankhe chitsanzo chimene shutter ndi makina kokha mkati mosamalitsa chimafotokozera kuthamanga sing'anga ntchito, koma zitsanzo zina shutter ndi sankalimbana nafe anakonza zogwiriziza wapadera.

Mpira "akuyandama" pulagi ndi adzatsekeredwa unkagunda kusindikiza zofewa mphete, yomwe ili pa mbali linanena bungwe, kupereka kusindikiza pazipita chipangizo. Koma zosiyanasiyana mavavu mpira amakhala ndi mokwanira mkulu otaya kukana, kotero izi vavu chitsekere wolemera akhoza kugwiritsidwa ntchito mu mipope ya awiri ochepa. Akonzeratu mu mayendedwe potseka zinthu odalirika, ndipo pamafunika khama kochepa, koma zinalengedwera ndi zovuta kwambiri kusamalira iwo.

Mu mmunsi mwa mchitidwe lanu ndi lug ofananira amene yakwera ku nyumba ya valavu mpira kudzera mwa mayendedwe kumveka kapena anagubuduza. Ubwino wa mavavu mpira monga kuphweka kulengedwa, ntchito yabwino, kukula yaing'ono, kudalirika ndi mkulu zikayamba, mawonekedwe yosavuta otaya mbali anasiya mwa iwo n'kupita wakufa. Atembenuza ndi Crane ndi kuthera nthawi pang'ono, ndipo mavavu akhoza kugwiritsidwa ntchito mitundu yonse ya zakhudzana ndi viscous madzi, slurries ndi slurries, suspensions osiyana.

The sangathe kuli nthambi mpira, amene anapereka pomanga kutonthoza chogwirira, ndi kukhalapo kwa "akufa" zone lili kumayambiriro, ndipo chitsanzo ndi cholembera-ngati nkhosa mosatsata opanda. Mavavu zonse zinabala mtundu kuti athe lotseguka kapena kutseka ndimeyi atembenuza mpira yokha. Ngati vavu amadziwa otseguka pamene tikudutsa therethrough ntchito otaya zomvetsa madzimadzi ndi negligible. Mofanana Mbali wapatali anapanga zofunika valving chipangizo ili pa mapaipi waukulu mu gawo liniya.

Kuchepetsa makokedwe ndi miyeso kuti zifunika mu nthawi ya mavavu ulamuliro Mankhwalawa amagwiritsidwa ntchito mavavu mwapang'ono, choncho zovuta akhoza kwambiri kuchepetsa ntchito kachitidwe zamakono ..
