Kungani i-Piston ye-Generator engu-150KVA Isethwe Kulula Ukuhluleka

I-Piston iyingxenye encane yesethi yejeneretha yedizili engu-150KVA, kodwa ingenye yezingxenye ezibalulekile zejeneretha yedizili.Ngenxa yokuthi indawo yayo yokusebenza imbi kakhulu, ngokuvamile iba nezinkinga ezinjalo.Ake sibheke ukuthi yini ebangela ukwehluleka kwepiston.

Ngesikhathi sokusebenzisa Isethi yejeneretha engu-150KVA , izingxenye zepiston ezigqoke kalula ziyi-groove yendandatho, elandelwa yimbobo yesiketi kanye nephini.Ngokuvamile kuba nezikhala ezimbalwa ku-piston, kodwa i-ring groove eduze negumbi elivuthayo yiyona esengozini kakhulu yokugqoka.Uma i-ring groove isiguge kakhulu, igesi ephezulu yokushisa kanye ne-high-pressure izongena ku-crankcase futhi amafutha enjini amaningi azongena ekamelweni lokushisa.Ngemva kokulimala kwepiston, ngokuvamile ingahlolwa ngokubhekwa nokwahlulela.Uma ipayipi le-exhaust lenjini kadizili likhipha intuthu eluhlaza okwesibhakabhaka noma amandla encipha, amaphutha amaningi avela ku-ring groove noma endebeni ye-piston.Lapho injini ye-diesel ingenzi lutho, kuzwakala umsindo wokuvuza komoya ku-crankcase.Kunzima ukulungisa ipiston.Lapho i-piston igugile kakhulu, ngokuvamile ishintshwa nge-piston entsha yemodeli efanayo.

A.Izimbangela zepulaki yenjini engaphezulu ukushaya ikhanda lesilinda.

1.Ngesikhathi sokulungisa noma ukuhlanganisa, phonsa ngephutha izikulufo ezincane, amantongomane noma izikulufu epayipini lokudonsa amanzi noma i-piston.Noma ncela isilinda ngesikhathi sokumunca, noma i-gasket encane inamathele ngaphansi kwekhanda le-cylinder.Ngesikhathi kufakwa i-cylinder head, akuzange kuqashelwe ukuthi ihlale ekamelweni elivuthayo, futhi kunomsindo ongajwayelekile ngemva kokuqala injini, okwenza ukuthi umqhele we-piston ushayisane nekhanda le-cylinder.

2.Ukulimala kwephedi yenduku yokuxhuma kuzophinde kubangele ukuthi i-piston ithinte ikhanda le-cylinder.Lolu hlobo lokushayisana ukushayisana kwe-inertial futhi akubangelwa induku ende yokuxhuma noma i-piston.Ngakho-ke, lapho uphendula i-flywheel, i-piston ayitholakali ithinta ikhanda le-cylinder.Izwakala kuphela lapho i-generator ye-diesel isebenza (umsindo ukhuphuka ngokunyuka kwejubane elijikelezayo, futhi umsindo ulula ngesivinini esiphansi).

3.Lapho ufaka ikepisi elithwele induku yokuxhuma, faka i-bearing cap ngokuhlehla noma ufake ezinye izigqoko zokuxhuma ngokungalungile.Nakuba isikulufu siqinisiwe, iBush lisamise okweqanda (umzimba wenduku yokuxhuma kanye nesembozo zicutshungulwa ngazimbili futhi azikwazi ukushintshwa).I-inertia yokuzungezisa yenza i-piston ishaye inhloko yesilinda, okuholela kumsindo okhanyayo, ophukayo futhi oqinile.Kusenomsindo ngemva kokunqunywa kwamafutha, okungapheli, futhi ikhanda le-cylinder lidlidliza kakhulu.Ngakho-ke, ukunakwa okukhethekile kufanele kukhokhwe kuleli phuzu ngesikhathi sokugcinwa.

4.Ngemva kokuba ibhowodi yenduku yokuxhuma ixegisiwe, izophinde ibangele ukuthi i-piston ishayisane nekhanda le-cylinder.Amabhawudi afanelekile azokhethwa futhi aqiniswe njengoba kudingeka.Akuvunyelwe ukusebenzisa amabhawodi amadala.

B. Isilinda sokuhlikihla iPiston.

I-piston surface ilukhuni ngenxa yokungqubuzana okomile;Lapho ijeneretha kadizili ihambisana nokungqongqoza kancane kusilinda, amadiphozithi ensimbi akhiqizwa endaweni yepiston.Ngalesi sikhathi, uma ingalungiswanga ngesikhathi, i-piston kanye ne-cylinder liner izokhiywa.

1. Ukusebenza ngokweqile kwejeneretha ye-diesel kanye nezinkinga ohlelweni lokupholisa ifilimu kawoyela eyonakele, okuholela ekudonsweni kwesilinda.

2. Amafutha okugcoba mancane kakhulu ukuze adlale indima ephumelelayo ekugcobiseni, noma ukwehluleka kwesistimu yokugcoba kuholela ekwandeni kwe-coefficient ye-friction phakathi kwe-piston kanye ne-cylinder liner, okuholela ekudonsweni kwesilinda.

3. Ukulungiswa okungalungile kwesikhathi sokuthungela kwejeneretha kadizili kubangela ukungqongqoza nokonakala kwejeneretha kadizili, kanye nezinga lokushisa eliphakeme kakhulu generator diesel ibhubhisa ifilimu yokuzivikela yamafutha, okuholela ekudonseni isilinda.

4. Ukufakwa okungalungile kwepiston noma ukufakwa okungafanele kwe-piston kanye ne-cylinder liner, futhi imvume enkulu kakhulu noma encane kakhulu kungaholela ekudonsweni kwesilinda.

5. Isihlungi somoya, isihlungi samafutha okugcoba kanye nesihlungi sikaphethiloli sesethi ye-diesel generator akushintshwa futhi kuhlanzwe ngesikhathi, okungcolisa indawo yokusebenza yesilinda futhi kuholele ekudonsweni kwesilinda.

6. Ukugoba kwenduku kushintsha indlela yokugijima yepiston, okuholela ekudonsweni kwesilinda.

7. I-piston ring ibambekile futhi iringi yepiston iphukile, okuholela ekudonsweni kwesilinda.

8. Kukhona ikhabhoni eningi kakhulu kusethi yejeneretha, futhi ikhabhoni ewile ingena ku-cylinder block, okuholela ekudonsweni kwesilinda.

Ngenhla yizizathu zokuhluleka kwe-piston ye-generator engu-150KVA, uma sisebenzisa isethi yejeneretha yedizili, uma sithola amaphutha, kufanele simise umshini ukuze sihlole futhi sixazulule amaphutha ngesikhathi.Ngakho lokho kunganciphisa ukulimala komshini.
