Pali zisanu ndi chimodzi 24-inchi nkhani yogawa ozungulira madzi pampu ntchito imeneyi, anaika panja. Magawo a pompopompo ndi awa:

Q=3000m3/h, H=70m, N=960r/m (liwiro lenileni limafika 990r/m)

Okonzeka ndi galimoto mphamvu 800kW

Ma flanges pa malekezero onse a mphira wowonjezera wolumikizana amalumikizidwa ndi mapaipi motsatana, ndipo ma flanges pa malekezero onsewo samalumikizidwa mwamphamvu ndi mabawuti aatali.

pambuyo papompa yogawaimayikidwa, kukonza zolakwika kumayamba chimodzi ndi chimodzi. Izi zimachitika panthawi ya debugging:

1. Zonse zoyambira pampu ndi poyimitsa simenti paipi yotulutsa zimachotsedwa. Mayendedwe osunthika ali monga akuwonetsedwa pachithunzi cha chipangizocho: pampu imasunthira kumanja, ndipo cholumikizira chokhazikika chimasunthira kumanzere. Mipando ya simenti yamapampu angapo idasweka chifukwa chakusamuka.

2. Kuwerengera kwamagetsi kumafika ku 0.8MPa valve isanatsegulidwe, ndipo ili pafupi ndi 0.65MPa valve itatsegulidwa pang'ono. Kutsegula kwa valavu ya gulugufe yamagetsi ndi pafupifupi 15%. Kutentha kwa kutentha ndi kugwedezeka kwa matalikidwe a ziwalo zoberekera ndi zachilendo.

3. Pambuyo poyimitsa mpope, yang'anani kugwirizanitsa kwazitsulo. Zimapezeka kuti zolumikizana ziwiri zamakina ndi mpope ndizolakwika kwambiri. Malinga ndi kuwunika kochitidwa ndi oyika, kulakwitsa kwakukulu ndi mpope #1 (kusokoneza 1.6mm) ndi mpope #5 (kusokoneza). 3mm), mpope wa 6# (wogwedezeka ndi 2mm), mapampu ena ali ndi mawaya makumi angapo olakwika.

4. Pambuyo pokonza ndondomekoyi, poyambitsanso galimotoyo, wogwiritsa ntchitoyo ndi kampani yoyikapo adagwiritsa ntchito chizindikiro choyimba kuti ayese kusamuka kwa phazi la mpope. Kuchuluka kwake kunali 0.37mm. Panali kubwereranso pambuyo poyimitsa mpope, koma malo a phazi la mpope sakanatha kubwezeretsedwa.

Ngozi yosweka ya shaft idachitika pampope #5. Mtsinje wa mpope wa 5# usanaduke, umayenda mozungulira 3-4, ndipo nthawi yonse yothamanga inali pafupifupi maola 60. Pambuyo poyendetsa komaliza, chitsulocho chinathyoka pogwira ntchito mpaka usiku wotsatira. Shaft yosweka ili kumapeto kwa mapewa oyendetsa, ndipo gawo la mtanda limapendekera pang'ono pakatikati pa shaft.

Kuwunikidwa kwa chomwe chayambitsa ngozi: Ngozi yosweka shaft idachitika papampu ya 5#. Pakhoza kukhala mavuto ndi khalidwe la shaft palokha kapena zinthu zakunja.

1. Mtsinje wa mpope wa 5# wathyoka. Sizinganenedwe kuti pali zovuta zamtundu wa 5 # pampu shaft. Mavutowa atha kukhala zolakwika mu shaft material yokha, kapena atha chifukwa cha kupsinjika komwe kumachitika chifukwa cha kusakhazikika kwa arc kwa 5# pump shaft undercut groove. Ichi ndichifukwa chake 5# shaft yapampu idasweka. Axis imayambitsa zovuta za umunthu.

2. Mtsinje wosweka wa mpope wa 5 # umagwirizana ndi kusamuka kwa mpope chifukwa cha mphamvu yakunja. Pansi pa mphamvu yakunja, kupotoza kumanzere ndi kumanja kwa 5# phatikizani pampu ndikokulirapo. Mphamvu yakunja iyi imapangidwa chifukwa cha kupsinjika komwe kumapangidwa ndi kuthamanga kwa madzi papaipi yotulutsa (kuvuta uku F pomwe P2 = 0.7MPa:

F=0.7×10.2×(πd2)÷4=0.7×10.2×(π×802)÷4=35.9T, pamene valve yatsekedwa, P2=0.8MPa, panthawiyi F=0.8×10.2×(π× 802 ) ÷4 = 41T), mphamvu yokoka yaikulu yoteroyo siingathe kupirira ndi kuuma kwa khoma la chitoliro cha rabara, ndipo iyenera kupitirira kumanzere ndi kumanja. Mwanjira imeneyi, mphamvu imafalikira kumanja kwa mpope, ndikupangitsa kuti isamuke, ndi kumanzere kupita ku pier ya simenti, kuchititsa kuti ngati chitsulocho chili champhamvu ndipo sichikugwa, kusuntha kwa mpope kumanja. adzakhala wamkulu. Zowona zawonetsa kuti ngati pier ya simenti ya pampu ya 5# sinasweka, kusamuka kwa mpope 5# kudzakhala kwakukulu. Chifukwa chake, pambuyo pa kuyimitsidwa, kusokonekera kumanzere ndi kumanja kwa kuphatikiza kwa mpope 5# kudzakhala kwakukulu kwambiri (akaunti yapagulu: Pump Butler).

3. Chifukwa kulimba kwa khoma la chitoliro cha rabara sikungathe kupirira kuponyedwa kwamadzi kwakukulu ndipo kumatalikirana kwambiri, potulutsa mpweya umayendetsedwa ndi mphamvu yaikulu yakunja (zolowera ndi zotuluka za mpope sizingathe kupirira mphamvu yakunja ya payipi), kupangitsa kuti thupi la mpope lisunthike komanso kulumikizako kumasokonekera. , mitsinje iwiri ya makina ndi kugawanika pompa kake kuthamanga mosasunthika, chomwe ndi chinthu chakunja chomwe chimapangitsa shaft ya 5 # pampu kusweka.

Yankho: Lumikizani molimba zigawo za tayala ndi zomangira zazitali, ndipo lolani chitoliro chotulutsa chitambasulidwe momasuka. Kusamuka komanso kusweka kwa shaft sikudzachitikanso.
