Why choose variable frequency cranes over conventional ones?

Cranes ni umuhuza w'ingenzi hagati y'ibikoresho, imirongo y'umusaruro n'ibicuruzwa byarangiye. Uko ubusabe bw'inganda zigezweho n'umusaruro w'ibidukikije bwiyongera, intege nke za cranes zihoraho zirushaho kugaragara. Ariko, cranes zihindagurika zagiye zimenyekana nk'amahitamo akunda ibigo byinshi kubera inyungu zitangwa n'iterambere ry'ikoranabuhanga. Ni gute cranes zihindagurika zigereranywa na cranes zisanzwe?

I. Energy efficiency and cost reduction: Long-term operating costs cut by 20% -30%.

Ikibazo cyingenzi kuri cranes zisanzwe ni ikoreshwa ry'ingufu nyinshi. Moteri zihoraho zikora ku muvuduko udasanzwe, zikomeza gutanga ingufu zuzuye hatitawe ku mutwaro. Ibi bigabanya amashanyarazi kandi byongera umutwaro wa grid bitewe n'ubwiyongere bw'ubu.

Ku rundi ruhande, cranes zihinduranya zikoresha tekinoroji yo kugenzura umuvuduko wa moteri kugirango ihindure umuvuduko wa moteri ukurikije ibisabwa n'imizigo. Mugihe cyo kuzamura imizigo yoroheje cyangwa kugenda hamwe n'umuzigo wubusa, kumzekelo, moteri ihita igabanya umuvuduko kugirango igabanye ikoreshwa ry'ingufu. Mugihe cyakazi cyuzuye, hagati aho, kugenzura umuvuduko mwiza birinda imbaraga zitunguranye.

Fata Variable Frequency Gantry Crane yateguwe na Henan Mine Crane ya Baosteel Group, kurugero. Moteri yayo ihoraho ya magnet synchronous variable-frequency igabanya ikoreshwa ry'ingufu ku kigero cya 20% -30% ugereranyije na moteri za asynchronous zikoreshwa muri cranes zisanzwe zihoraho.

Byongeye kandi, crane ya VFD ikoresha uburyo bwo gutangiza byoroshye mugihe cyo gukora, hamwe na kimwe cya gatatu gusa cya cranes zisanzwe. Ibi birinda ingaruka ku muyoboro wamashanyarazi kandi bigabanya ihagarikwa ryibikoresho biterwa n'ihindagurika ry'umuvuduko wa voltage.

II. Precision control: Minimising Sway and Impact to Enhance Operational Efficiency and Material Safety

Cranes zisanzwe, zigabanyirizwa na moteri zigendera ku muvuduko udasanzwe, akenshi zihura na braking butunguranye no kwihuta.

Ku rundi ruhande, cranes zihinduranya zigera ku muvuduko mwiza no guhagarara neza binyuze mu kugenzura PLC na VFD.

Umuvuduko wa moteri urashobora kwiyongera buhoro buhoro kuva kuri 0 kugeza ku muvuduko wagenwe, hamwe no kugabanuka buhoro buhoro mugihe cyo guhagarara. Umuvuduko w'imizigo ugumizwa kuri cm 5, bigatuma izi cranes zikwiriye cyane gukoreshwa mu nganda z'ibyuma, aho zishobora gutwara ibyuma by'ubushyuhe bwinshi hamwe n'amasahani manini ya toni.

Positioning accuracy: Sisitemu ihinduka-frequency igenzura neza umuvuduko wurugendo no gutangiza / guhagarara imyanya ya hoists nyamukuru n'iy'abafasha, igera ku buziranenge bwa ±5 mm. Mugihe cyo gufata kontineri na cranes ya gantry y'icyambu, guhuza neza kugerwaho bitabaye ngombwa ko habaho amavugurura asubirwamo, kongera imikorere hejuru ya 30%.

III. Extended Equipment Lifespan: Reduced component wear and lower maintenance costs:

Cranes zisanzwe zishyira ibice by'ibanze ku ngaruka zihoraho mugihe cyo gutangira no guhagarara, bigatuma habaho kwambara ibinyabiziga bya moteri hakiri kare bitewe n'ubwiyongere bw'ubu.

Variable frequency cranes minimise component damage through two key design features:

Soft start / stop minimises mechanical impact: Current surges are eliminated during startup, reducing motor and bearing wear rates by 40%. Hard mechanical braking is also eliminated during stops, extending brake pad lifespan to 12-18 months between replacements and reducing maintenance frequency.

Muri make, variable frequency cranes ni amahitamo meza yo gushora imari mu gihe gito n'inyungu z'igihe kirekire.

Nubwo cranes zihindagurika zifite ibiciro byo kugura ibicuruzwa bihanitse ugereranije na cranes zisanzwe, ni amahitamo meza yo gushora imari yigihe gito hamwe ninyungu z'igihe kirekire. Ariko, uhereye ku myumvire y'imikorere y'igihe kirekire, zikwiriye by'umwihariko ku bihe bisaba ibikorwa byo hejuru, umutekano mwinshi, nko mu nganda z'ibyuma, icyambu n'imashini ziremereye.

Nk'isosiyete itanga crane ku isi, Henan Mine Crane itanga ibicuruzwa byuzuye kuva kuri toni 5 kugeza kuri 500. Dutanga ibishushanyo byihariye bishingiye ku bishushanyo by'urubuga rw'abakiriya, imizigo n'ibipimo by'ibidukikije. Serivisi zacu zuzuye z'ubuzima zitanga ibisubizo bimwe, harimo igenzura ry'ahantu, gutegura igishushanyo mbonera , gushyiramo, kohereza no kubungabunga buri gihe.
