Kune matanhatu 24-inch split case pombi dzemvura dzinotenderera muchirongwa ichi, dzakaiswa pamhepo. Iyo pombi nameplate paramita ndeiyi:

Q=3000m3/h, H=70m, N=960r/m (kumhanya chaiko kunosvika 990r/m)

Akashongedzerwa injini simba 800kW

Maflange ari kumativi ose ejoint yekuwedzera kwerabha akabatana nemapombi zvakateerana, uye maflange pamativi ese ari maviri pachawo haana kusimba akabatana nemabhaudhi marefu.

mushurepombi yekuparadzanisa kesiyakaiswa, debugging inotanga imwe neimwe. Mamiriro ezvinhu anotevera anoitika panguva yekugadzirisa:

1. Zvose chigadziko chepombi uye simenti-yakagadziriswa buttress yepombi yekuburitsa inobviswa. Iyo nzira yekutamisa inoratidzwa mune schematic dhizaini yechishandiso: pombi inofamba ichienda kurudyi, uye yakagadziriswa buttress inoenda kuruboshwe. Zvigaro zvesimende zvemapombi akati wandei zvakatsemuka nekuda kwekutamiswa.

2. Chiyero chekumanikidza kuverenga kunosvika 0.8MPa isati yavhurwa valve, uye inenge 0.65MPa mushure mekunge valve yavhurwa zvishoma. Kuvhurwa kwevhavhavha yegetsi butterfly inenge 15%. Iyo tembiricha inokwira uye vibration amplitude yezvikamu zvinotakura zvakajairika.

3. Mushure mokumisa pombi, chengetedza kurongeka kwekubatanidza. Inowanikwa kuti iyo miviri yakabatana yemuchina uye pombi yakasarudzika zvakanyanya. Zvinoenderana nekuongororwa kwakaitwa nemuisi, iyo yakanyanya kusarongeka ndeye pombi #1 (misalignment 1.6mm) uye pombi #5 (misalignment). 3mm), 6# pombi (yakadzedzereka ne2mm), mamwe mapombi ane gumi ewaya dzekusarongeka.

4. Mushure mekugadzirisa kurongeka, paunotangazve motokari, mushandisi uye kambani yekuisa yakashandisa dhiyabhorosi yekuyera kutama kwetsoka yepombi. Iyo yepamusoro yaive 0.37mm. Pakange paine rebound mushure mekunge pombi yamiswa, asi nzvimbo yetsoka yepombi haina kukwanisa kudzoreredzwa.

Tsaona yakatyoka shaft yakaitika papombi #5. Isati yaputsika shaft ye5# pombi, yaimhanya zvishoma nezvishoma 3-4 nguva, uye nguva yese yekumhanya yaive maawa makumi matanhatu. Mushure mekutyaira kwekupedzisira, ekisi yakatsemuka panguva yekushanda kusvika manheru anotevera. Iyo shaft yakatyoka iri pakupera kweyekutyaira magumo ekumisa pfudzi, uye chikamu chemuchinjikwa chakarerekera zvishoma kusvika pakati pe shaft.

Ongororo yezvakakonzera tsaona: Tsaona yekupwanya shaft yakaitika pa5# pombi. Panogona kunge kune matambudziko nehutano hwe shaft pachayo kana zvinhu zvekunze.

1. Iyo shaft ye5# pombi yakaputsika. Izvo hazvigone kutongerwa kunze kuti kune matambudziko emhando ne5 # pombi shaft. Aya matambudziko anogona kunge ari hurema mune shaft zvinhu pachayo, kana anogona kukonzerwa nekunetsekana kunokonzerwa nekusajaira arc kugadzirisa kwe5# pombi shaft undercut groove. Ichi ndicho chikonzero nei iyo 5# pombi shaft yakaputsika. Axis inokonzeresa nyaya dzehunhu.

2. Iyo yakaputsika shaft ye5 # pombi ine chekuita nekusimuka kwepombi kunokonzerwa nekunze kwesimba. Pasi pekuita kwesimba rekunze, kusarongeka nekurudyi kwe5# pombi yekubatanidza ndiyo yakakura. Iri simba rekunze rinogadzirwa nekuda kwekukakavadzana kunoitwa nekudzvanywa kwemvura papombi yekuburitsa (iyi tension F kana P2 = 0.7MPa:

F=0.7×10.2×(πd2)÷4=0.7×10.2×(π×802)÷4=35.9T, kana vharuvhu yakavharwa, P2=0.8MPa, panguva ino F=0.8×10.2×(π× 802 )÷4=41T), simba guru rakadaro rekudhonza harigoni kumira nekuoma kwemadziro epombi yerabha, uye inofanira kuenderera kuruboshwe uye kurudyi. Nenzira iyi, simba rinoparidzirwa kurudyi kune pombi, zvichiita kuti iparadze, uye kuruboshwe kune pier yesimende, zvichiita kuti Kana iyo buttress yakasimba uye isingaputsi, kutama kwepombi kurudyi. zvichava zvikuru. Chokwadi chakaratidza kuti kana simende pier ye5# pombi isina kutsemuka, kutamiswa kwepombi ye5# kuchava kukuru. Naizvozvo, mushure mekumira, kuruboshwe uye kurudyi kusarongeka kwekubatana kwe5# pombi ichave yakakura (yeruzhinji account: Pump Butler).

3. Nekuda kwekuti kuoma kwemadziro epombi yerabha hakugoni kumira kusundwa kwemvura kwakakura uye kwakareba, pombi inobuda inoiswa pasi pekusundidzira kwekunze kukuru (kupinza nekubuda kwepombi hakugoni kumira nesimba rekunze repombi), kukonzeresa kuti muviri wepombi uchinje uye kubatana kutsemuka. , mashafu maviri emuchina uye akatsemuka pombi yemhosva mhanya usiri-concentrically, chiri chinhu chekunze chinoita kuti shaft ye5# pombi ipambuke.

Solution: Rigidly batanidza zvikamu matayi neakareba screws, uye bvumira kuburitsa pombi kutambanudza zvakasununguka. Displacement uye shaft breakage matambudziko hazvichaitike.
