Yiziphi izinyathelo zokuphepha zokuvula nokucisha isithando somlilo sensimbi?

1. Bheka ngaphambi kokuqala isithando somlilo sensimbi:

Hlola umzila wamanzi nesekethe njalo ngaphambi kokuqala umshini. Qinisekisa ukuthi wonke amapayipi amanzi avuliwe futhi ubheke isekethe ukuthi akukho yini okungajwayelekile njengezikulufo ezikhululekile.

Okwesibili, indlela yokuqala isithando somlilo sensimbi:

Vula ukunikezwa kwamandla kwekhabethe lamandla wamandla aphakathi nendawo. Cindezela “control power on button”, ilambu lesikhombi samandla okuvula livuliwe, vala inkinobho enkulu yesekethe, ilambu lesikhombi sephutha liyacima, bese i-voltmeter yeDC kufanele ibonise amandla kagesi amabi. Bese uguqula kancane amandla anikezwe i-potentiometer abe yinani elikhudlwana ngenkathi ubheka imitha kagesi, i-voltmeter ye-DC ikhombisa ukwanda.

1. Lapho i-voltage ye-DC yeqa u-zero, amamitha amathathu wamaphakathi we-frequency voltage, i-DC voltage, namandla asebenzayo akhuphuka ngasikhathi sinye, futhi kuzwakala nomsindo wamaza omaphakathi ukukhombisa ukuqala okuyimpumelelo. Amandla angandiswa kumandla adingekayo we-positioner.

2. Lapho i-voltage ye-DC yeqa u-zero, amamitha amathathu wamandla wamaphakathi amaphakathi, i-DC yamanje, namandla asebenzayo akhuphuki ngasikhathi sinye futhi awukho umsindo ojwayelekile wemisindo ephakathi ongazwakala, okukhombisa ukuthi ukuqala akuphumelelanga, futhi i-potentiometer yamandla kufanele iguqulwe ibe ubuncane futhi iqale phansi.

3. Setha kabusha isithando somlilo sensimbi:

Uma i-over-current noma i-over-voltage kwenzeka ngesikhathi sokusebenza kwemishini, inkomba yephutha kuphaneli yomnyango izobe ivuliwe. I-potentiometer kufanele iguqulwe ibe ubuncane, cindezela “inkinobho yokusetha kabusha” isibani sephutha sivuliwe, bese ucindezela “inkinobho yokuvala isekhethi enkulu”, bese uqala kabusha.

Okwesine, indlela yokuvala isithando somlilo sensimbi:

Guqula i-potentiometer ibe ubuncane, cindezela u- “Main circuit open” bese uhlukanisa iswishi enkulu, bese ucindezela u- “Control power off”. Uma okokusebenza kungasasetshenziswa, ukunqanyulwa kwamandla ekhabethe lamandla amaphakathi amaphakathi kufanele kunqanyulwe.
