Zambiri za PDM Drill

Kubowola kwa PDM (Progressive Displacement Motor drill) ndi mtundu wa chida chobowola mphamvu chapansi chomwe chimadalira pobowola madzimadzi kuti asinthe mphamvu zama hydraulic kukhala mphamvu zamakina. Mfundo yake yogwiritsira ntchito imaphatikizapo kugwiritsa ntchito pampu yamatope kunyamula matope kudzera pa valve yodutsa kupita ku injini, kumene kusiyana kwapakati kumapangidwira polowera ndi kutuluka kwa injini. Kusiyanitsa kumeneku kumapangitsa kuti rotor izungulire mozungulira ma axis a stator, kenako imasamutsa liwiro lozungulira ndi torque kudzera m'malo olumikizirana onse ndikuyendetsa shaft mpaka pobowola, kumathandizira pakubowola koyenera.

Zigawo Zazikulu

Kubowola kwa PDM kumakhala ndi zigawo zinayi zazikulu:

1. Bypass Valve: Kuphatikizika ndi thupi la valavu, manja a valve, pakati pa valve, ndi kasupe, valavu yodutsa imatha kusintha pakati pa zodutsa ndi zotsekedwa kuti zitsimikizire kuti matope akuyenda kudzera mu galimotoyo ndikutembenuza mphamvu. Pamene matope akuyenda ndi kukakamizidwa kufika pazikhalidwe zokhazikika, chigawo cha valve chimasunthira pansi kuti chitseke doko lodutsa; ngati otaya ndi otsika kwambiri kapena mpope kusiya, kasupe amakankhira pachimake valavu mmwamba, kutsegula kulambalala.
2. Galimoto: Wopangidwa ndi stator ndi rotor, stator imakhala ndi mphira, pamene rotor ndi screw-shelled screw. Kugwirizana pakati pa rotor ndi stator kumapanga chipinda chosindikizira cha helical, chomwe chimathandiza kutembenuka kwa mphamvu. Chiwerengero cha mitu pa rotor chimakhudza mgwirizano pakati pa liwiro ndi torque: rotor imodzi yamutu imapereka liwiro lapamwamba koma torque yochepa, pamene rotor yamutu yambiri imachita zosiyana.
3. Universal Joint: Chigawochi chimasintha kayendedwe ka pulaneti ya injini kukhala kasinthasintha wokhazikika wa shaft yoyendetsa, kutumiza torque yopangidwa ndi liwiro ku shaft yoyendetsa, yomwe imapangidwa mosinthika.
4. Drive Shaft: Imasamutsa mphamvu yozungulira ya mota ku pobowola pomwe imapirira ma axial ndi ma radial katundu wopangidwa ndi kubowola. Kapangidwe kathu ka shaft kamene kali ndi chilolezo, kumapereka moyo wautali komanso kuchuluka kwa katundu.

Zofunika Kugwiritsa Ntchito

Kuti muwonetsetse kuti kubowola kwa PDM kukuyenda bwino, izi ziyenera kutsatiridwa:

1. Zofunikira pakubowola zamadzimadzi: Kubowola kwa PDM kumatha kugwira ntchito bwino ndi mitundu yosiyanasiyana ya matope obowola, kuphatikiza mafuta, emulsified, dongo, ngakhale madzi abwino. Kukhuthala ndi kachulukidwe ka matope sikukhudza kwambiri zida, koma zimakhudza mwachindunji kuthamanga kwadongosolo. Mchenga womwe uli m'matope uyenera kusungidwa pansi pa 1% kuti upewe zotsatira zoyipa pakugwiritsa ntchito kwa chida. Mtundu uliwonse wa kubowola umakhala ndi njira yolowera, yomwe imakhala yabwino kwambiri nthawi zambiri imapezeka pakatikati pamtunduwu.
2. Zofunikira za Kupanikizika Kwamatope: Kubowolako kukayimitsidwa, kutsika kwapansi pamatope kumakhala kosalekeza. Pamene kubowola kumakhudza pansi, kuthamanga kwa kubowola kumawonjezeka, zomwe zimapangitsa kuti matope aziyenda komanso kuthamanga kwa pampu. Othandizira angagwiritse ntchito njira zotsatirazi kuti aziwongolera:

Bit Pump Pressure=Kuzungulira Pampu Kupanikizika + Chida Chonyamula Kupanikizika Kutsika

Kuthamanga kwa pampu yozungulira kumatanthawuza kuthamanga kwa mpope pamene kubowola sikukhudzana ndi pansi, komwe kumadziwika kuti kutsika kwapampu. Pamene kuthamanga pang'ono mpope kufika pazipita analimbikitsa kuthamanga, kubowola amapanga mulingo woyenera makokedwe; kuwonjezereka kowonjezereka kwa kuthamanga kwa kubowola kudzakweza kuthamanga kwa mpope. Ngati kukakamizidwa kupitilira malire apangidwe, ndikofunikira kuti muchepetse kuthamanga kwapabowo kuti mupewe kuwonongeka kwagalimoto.

Mapeto

Mwachidule, mapangidwe ndi zofunikira zogwirira ntchito za PDM drill zimagwirizana kwambiri. Mwa kulamulira bwino kayendedwe ka matope, kupanikizika, ndi makhalidwe a matope, munthu akhoza kuonetsetsa kuti ntchito yoboola bwino ndi yotetezeka. Kumvetsetsa ndikuzindikira magawo ofunikirawa kumatha kupititsa patsogolo magwiridwe antchito komanso chitetezo cha ntchito zoboola.
