Yiziphi izinto zokuvikela zamabhande okuthutha?

Amabhande okuthutha amabhande ezindaweni zezimboni, njengezindawo ezibamba amalahle, afakwe izinto ezihlukahlukene zokuvikela ukuze kuqinisekiswe ukuphepha kwesistimu, ukuvikela okokusebenza, nokuvikela abasebenzi. Lezi zixhobo zenzelwe ukuvimbela izingozi, ukubona ukungasebenzi kahle, nokuvikela emonakalweni webhande nezinye izingxenye zesistimu.

Idivayisi yokuvikela i-conveyor yebhande

1. Donsa Ukushintsha Kwentambo

Inhloso: Idivayisi yokumisa izimo eziphuthumayo.

Umsebenzi: Amaswishi ezintambo zokudonsa afakwe ngobude bebhande lokudlulisa. Uma zidonswa, zicupha isitobhi esiphuthumayo se-conveyor, okuvumela abasebenzi ukuthi bamise ibhande ngokushesha esimweni esiphuthumayo noma ukungasebenzi kahle.

Indawo: Ivamise ukugxunyekwa eceleni kwe-conveyor.

2. I-Belt Sway (Ukungahambi kahle) Shintsha

Inhloso: Ithola ukungahambi kahle kwebhande noma ukunyakaza.

Umsebenzi: I-belt sway switch ithola ukuchezuka kwebhande endleleni yalo evamile. Uma ibhande liqala ukukhukhuleka lisuke phakathi nendawo, iswishi ikhombisa isexwayiso noma ivale isistimu ukuze ivimbele umonakalo noma ukuchitheka kwempahla.

Indawo: Ifakwe emaphethelweni ebhande lokuthutha.

3. I-Belt Slip Switch

Inhloso: Ithola ukushelela kwebhande.

Umsebenzi: Le divayisi iqapha isivinini sebhande futhi iliqhathanise nesivinini se-pulley yokushayela. Uma ibhande lishelela noma lihamba kancane kune-pulley yokushayela (okukhombisa ukushelela kwebhande), iswishi izocupha i-alamu noma imise isithumeli.Indawo: Kufakwe eduze kwe-drive pulley.

4. I-Zero Speed Switch

Inhloso: Ithola ukuma kwebhande noma ukwehla.

Umsebenzi: Amaswishi esivinini anguziro aqapha ukunyakaza kwesithuthi futhi aqinisekise ukuthi ibhande lisebenza ngesivinini esinqunyiwe. Uma ibhande lima noma linciphisa ijubane ngokungalindelekile, iswishi izocupha isexwayiso noma imise isistimu yokuthutha.

Indawo: Ivamise ukugxunyekwa ku-pulley yomsila noma i-drive pulley.

5. I-Sequence Protection Switch

Inhloso: Iqinisekisa ukuqalisa okufanele nokulandelana kokuvala shaqa.

Umsebenzi: Lawa maswishi aqinisekisa ukuthi amaconveyor aqala futhi ame ngokulandelana okulungile, avimbele ukwakheka kwezinto engxenyeni eyodwa kuyilapho amanye angasebenzi.

Lokhu kubalulekile ezinhlelweni zokuthutha ezinezigaba eziningi.

Indawo: Ifakwe ezindaweni ezihlukahlukene ohlelweni, ngokuvamile ngokuhlanganyela nesistimu yokulawula.

6. Ukuvikelwa kokulayishwa ngokweqile (I-Overload Relay yamanje)

Inhloso: Ivikela injini nesistimu ekulayisheni ngokweqile.

Umsebenzi: I-relay yokuvikela ukulayisha ngokweqile iqapha amandla amanje emoto yokuthutha. Uma i-motor igcwele kakhulu (ngenxa yezinto ezeqile, okokusebenza okuminyene, njll.), i-relay izovala amandla enjini ukuvimbela ukulimala.

Indawo: Ifakwe kuphaneli yokulawula imoto.

7. Umtshina wezinyembezi zebhande

Inhloso: Ithola izinyembezi zebhande noma ukubhoboza.

Umsebenzi: Izitholi zokudabula amabhande zizwa umonakalo obonakalayo ebhandeni lokuthutha (isb., izinyembezi, izibhobo) futhi ngokushesha zimise isistimu ukuze kuvinjelwe ukulimala okwengeziwe ebhandeni noma kwezinye izingxenye.

Indawo: Ifakwe ngaphansi kwebhande lokuthutha ezindaweni lapho ukuchitheka kwempahla noma izinyembezi ezinkulu kungenzeka.

8. Inzwa yesivinini

Inhloso: Iqapha isivinini sokuthutha.

Umsebenzi: Izinzwa zesivinini ziqapha isivinini sokusebenza sebhande lokuthutha. Uma isivinini sebhande sichezuka kububanzi bayo obujwayelekile bokusebenza (kungaba ngokushesha kakhulu noma kancane kakhulu), inzwa icupha i-alamu noma imise isistimu.

Indawo: Kufakwe kuma-pulleys, ngokuvamile eduze neyunithi yokushayela.

9. Layisha Amaseli

Inhloso: Iqapha umthwalo wempahla ebhandeni.

Umsebenzi: Amaseli okulayisha akala isisindo sento ekhona ebhandeni lokudlulisa. Uma umthwalo wezinto ezibonakalayo udlula umthamo wedizayini yebhande, isistimu ingaqalisa ukuvala shaqa ukuze kuvinjelwe ukulayishwa ngokweqile.

Indawo: Ifakwe ezindaweni zamacebo ngaphansi kwebhande lapho okubalulekile kulayishwa khona noma kuhanjiswa khona.

10. I-Chute Block Switch (I-Chute Detector Exhunyiwe)

Inhloso: Ithola ukuvinjelwa kuma-chute okuthutha.

Umsebenzi: Lawa maswishi athola lapho okubalulekile kuvinjiwe noma kwenziwe isipele ku-chute yokukhipha. I-chute exhunyiwe ingaholela ekulayisheni ngokweqile nasekulimeni kwe-conveyor, ngakho-ke iswishi imisa ibhande ukuvimbela ukuchichima kokubalulekile.

Indawo: Kufakwe eduze kwama-chute noma ama-hopper.

11. Fire Detection Systems

Purpose: Detects fires on or near the conveyor belt.

Function: Fire detection systems, such as infrared scanners or heat sensors, detect hot spots or fires on the conveyor belt. When detected, the system can trigger alarms or activate fire suppression systems (e.g., water sprays or foam) to extinguish the fire.

Location: Installed above or near the belt, especially in high-risk areas such as transfer points or drive stations.

12. Automatic Belt Cleaning Systems

Purpose: Prevent material build-up on the belt.

Function: Belt cleaning systems, including scrapers and plows, remove material buildup on the belt to prevent misalignment, wear, or other damage. Though primarily a maintenance device, they can prevent accidents related to material spillage.

Location: Installed at the discharge or return end of the conveyor.

13. Thermal Protection

Purpose: Protects against overheating.

Function: Thermal sensors monitor the temperature of key conveyor components, such as the drive motor or bearings. If overheating is detected, the system can trigger an alarm or stop the conveyor to prevent component failure.

Location: Installed near drive units and motor housings.

14. Anti-Rollback Device

Purpose: Prevents belt rollback on inclined conveyors.

Function: On inclined conveyor systems, this device prevents the conveyor from rolling backward when power is cut or during a shutdown, ensuring safety and preventing equipment damage.

Location: Installed near the drive unit on inclined sections.

Summary of Key Protective Devices:

Pull cord switch: Emergency stop.

Belt sway switch: Detects belt misalignment.

Belt slip switch: Detects belt slippage.

Zero speed switch: Detects stoppage or slowdown.

Overload protection: Prevents motor overload.

Belt tear detector: Detects physical damage to the belt.
