Nthawi yowerengera nthawi ya ma flowmeter a clamp-on si yokhazikika ndipo iyenera kutsimikiziridwa kutengera kuphatikiza kwa zochitika zogwiritsidwa ntchito, malamulo amakampani, zofunikira pakuyeza molondola, komanso kukhazikika kwa zida. Nthawi zambiri imagawidwa m'magulu awiri: "nthawi zovomerezeka" ndi "mikhalidwe yapadera yoyambitsa."
I. Nthawi Yoyenera Yowerengera (Kutengera Kukhazikika kwa Ntchito)
Kutengera ndi kuuma kwa njira yogwiritsira ntchito, nthawi zambiri ma calibration intervals amagawidwa m'magulu motere:
| Chitsanzo cha Ntchito | Nthawi Yoyenera Yowerengera | Chifukwa Chachikulu |
|---|---|---|
| Njira zofunika kwambiri zamafakitale (monga kudyetsa mankhwala, kuyeza mphamvu kuti pakhale bata) | Zaka 1–2 | Zimakhudza chitetezo cha kupanga ndi kuwerengera ndalama, zomwe zimafuna kulondola kwambiri (nthawi zambiri ±1%–±2%), zomwe zimafuna kutsimikizika pafupipafupi. |
| Kuyang'anira ntchito za boma (monga ziwerengero za madzi/kuyenda kwa zinyalala, madzi oyendera HVAC) | Zaka 2–3 | Zofunikira pakulondola pang'ono (±2%–±3%) ndi mikhalidwe yogwirira ntchito yokhazikika, koma kuyang'ana nthawi ndi nthawi kutsatira deta ndikofunikira. |
| Kuyang'anira njira zonse (monga madzi ozizira a zida, kusamutsa zinthu zosafunikira) | Zaka 3–5 | Imayang'ana kwambiri pa "kuwunika momwe zinthu zilili" ndi zofunikira zochepa zolondola (±3%–±5%), zomwe zimathandiza kuti pakhale nthawi yayitali. |
II. "Mikhalidwe Yapadera Yoyambitsa" Yofuna Kukonza Koyambirira
Kukonza kapena kutsimikizira kuyenera kuchitika nthawi yomweyo ngati chilichonse mwa izi chachitika, ngakhale nthawi yokhazikika sinafike:
- Kusinthasintha kosazolowereka kwa deta yoyezera
Pamene mtengo wowonetsedwa wa flowmeter sukugwirizana kwambiri ndi momwe zinthu zilili (monga kuchuluka kwa pampu, kuthamanga kwa mapaipi, magawo a njira yopitira patsogolo/pansi) — mwachitsanzo, pampu yokhala ndi kayendedwe ka 100m³/h koma mitayo nthawi zonse imawonetsa 120m³/h kapena 80m³/h popanda chifukwa chomveka — kusokonekera kwa sensa kapena kusuntha kwa magawo kungakhale chifukwa, zomwe zimafuna kuyesedwa kuti zizindikire mavuto. - Zipangizo zomwe zimakhudzidwa ndi zinthu zoopsa kwambiri kapena kusokonezeka kwa thupi
- Kugwedezeka kwa mapaipi, kugwedezeka, kapena kusuntha komwe kumachepetsa kumatirira kwa sensa yolumikizira.
- Kusintha kwakukulu mwadzidzidzi kwa kutentha kapena kukhuthala kwa chinthu choyezedwa (monga, kuchokera pamalo ozungulira mpaka kupitirira 100°C) kapena kuwonjezeka kwa zinyalala/matumphu.
- Kusinthasintha kwa mphamvu yamagetsi, kugunda kwa mphezi, kapena chinyezi chambiri chomwe chingakhudze ma circuits amkati kapena kulondola kwa gawo loyezera.
- Pambuyo pochotsa/kuyikanso sensa
Masensa otsekereza magetsi amadalira kukhudzana kwamphamvu ndi kunja kwa payipi (kotetezedwa kudzera mu cholumikizira/zotsekereza magetsi). Kuchotsa ndi kuyikanso (monga, kukonza kapena kuyang'ana payipi) kungasinthe malo, ngodya, kapena kuthamanga kwa magetsi, zomwe zimafuna kukonzedwanso kuti zitsimikizire kulondola. - Malamulo a makampani kapena zofunikira pa kafukufuku
Makampani ena (monga mafuta, gasi, chakudya, mankhwala) amatsatira miyezo ya dziko kapena ma audit a chipani chachitatu, zomwe zimafuna kuyesedwa nthawi zina (monga, ma audit a chitetezo asanachitike chaka chilichonse) kuti atsimikizire kuti malamulo akutsatira (monga, Lamulo la Metrology la China la zida zogulira malonda). - Zipangizo zakale kapena zitakonzedwa
Ma flowmeter omwe akhala akugwira ntchito kwa zaka zoposa 5, kapena omwe ali ndi zigawo zapakati zomwe zasinthidwa (monga mainboard, masensa), amatha kugwedezeka ndikusowa kukonzedwa kuti abwezeretse kulondola.
III. Njira Zoyezera ndi Kuganizira
- Njira zodziwika bwino zowerengera
- Kuyerekeza koyerekeza kwa malo: Kugwiritsa ntchito choyezera kuyenda kwa madzi chonyamulika (monga choyezera kuyenda kwa madzi chonyamulika kapena choyezera kuyenda kwa madzi chonyamulika) kuti muyese payipi yomweyo, kuyerekeza kusiyana (kosavuta komanso kotsika mtengo pazochitika zambiri zamafakitale).
- Kuyesa kwa Laboratory: Kutumiza flowmeter ku bungwe lovomerezeka la CNAS kuti liyesedwe bwino pazida zoyezera mayendedwe (zolondola kwambiri, zoyenera kugulitsidwa kapena njira zofunika kwambiri).
- Njira zina za "kutsimikizira pang'ono" za tsiku ndi tsiku
Ngati palibe kuwerengera kovomerezeka, kufufuza kosavuta pogwiritsa ntchito "njira ya pipeline static volume" kungachitike: Tsekani ma valve akumtunda/pansi, lembani kukula kwa payipi, kutalika, ndi nthawi yodzaza payipi, kenako yerekezerani kuyenda kwa malingaliro ndi kuwerenga kwa mita (kuti mungowerenga mwachidule, osati m'malo mwa kuwerengera kovomerezeka).
Chidule
Nthawi yowerengera ya ma flowmeter a clamp-on ultrasound iyenera kukhala "yogwirizana ndi zosowa": chaka chimodzi mpaka ziwiri pazochitika zofunika kwambiri, zaka ziwiri mpaka zitatu pakugwiritsa ntchito nthawi zonse, ndi zaka zitatu mpaka zisanu pa ntchito zosafunikira kwenikweni. Iyeneranso kusinthidwa mosinthasintha kutengera mikhalidwe yapadera monga zolakwika pa data, kusokonezeka kwa zida, kapena zofunikira pamalamulo. Kuwerengera nthawi zonse kumatsimikizira kulondola kwa muyeso, kuzindikira zolakwika zomwe zingachitike msanga, ndikuwonjezera nthawi ya moyo wa zida.
