1. Taw qhia

Raws li cov cuab yeej tseem ceeb ntawm kev thauj mus los ntawm mine, lub mine hoist yog lub luag haujlwm rau kev nqa thiab txo cov neeg ua haujlwm, cov khoom siv, thiab lwm yam.Qhov kev nyab xeeb, kev ntseeg tau thiab kev ua haujlwm ntawm nws cov haujlwm ncaj qha cuam tshuam rau kev tsim khoom ntawm mine thiab kev nyab xeeb ntawm lub neej thiab khoom ntawm cov neeg ua haujlwm. Nrog rau kev txhim kho txuas ntxiv ntawm kev tshawb fawb niaj hnub thiab thev naus laus zis, daim ntawv thov ntawm cov hlau nplaum ruaj khov hauv kev tshawb fawb ntawm mine hoists tau maj mam dhau los.

Cov hlau nplaum tas mus li muaj ntau yam zoo xws li lub zog loj, kev ua haujlwm siab, thiab suab nrov tsawg. Kev siv lawv rau kuv cov hoists yuav tsum tau ua kom cov cuab yeej ua haujlwm tau zoo, thaum tseem coj cov cib fim tshiab thiab cov teeb meem ntawm kev ruaj ntseg.

2. Kev siv cov cuab yeej siv hlau nplaum ruaj khov hauv mine hoist drive system

(1) Cov hlau nplaum tas mus li synchronous lub cev muaj zog ua haujlwm

Cov hlau nplaum ruaj khov synchronous motors ua haujlwm raws li txoj cai ntawm electromagnetic induction. Lub hauv paus ntsiab lus tseem ceeb yog tias thaum peb-theem alternating tam sim no dhau los ntawm stator winding, rotating magnetic teb yog generated, uas interacts nrog lub magnetic teb ntawm cov hlau nplaum ruaj khov ntawm lub rotor, yog li tsim electromagnetic torque los tsav lub cev muaj zog tig. Cov hlau nplaum ruaj khov ntawm lub rotor muab lub zog sib nqus ntawm lub zog txuas ntxiv, tsis tas yuav txhim kho cov qauv tam sim no. conversion efficiency.Nyob rau hauv kuv hoist daim ntawv thov scenarios, lub cev muaj zog yuav tsum nquag hloov ntawm txawv kev khiav hauj lwm tej yam kev mob xws li hnyav load, tsawg ceev thiab lub teeb load, kev kub ceev. Cov hlau nplaum ruaj khov synchronous lub cev muaj zog tuaj yeem teb sai nrog nws cov yam ntxwv zoo torque kom ntseeg tau tias kev ua haujlwm du ntawm lub hoist.

(2). Kev txhim kho thev naus laus zis piv nrog cov tshuab tsav ib txwm muaj

1. Kev sib piv kev ua tau zoo

Cov tsoos mine hoists feem ntau yog tsav los ntawm lub qhov txhab-rotor asynchronous motors, uas muaj qhov ua haujlwm tsawg.Qhov kev poob ntawm asynchronous motors feem ntau suav nrog stator tooj liab poob, rotor tooj liab poob, hlau poob, mechanical poob thiab stray loss.Vim tias tsis muaj excitation tam sim no nyob rau hauv cov hlau nplaum tas li, nws yuav luag cov hlau nplaum synchronous lub cev muaj zog. Los ntawm kev sib piv ntawm cov ntaub ntawv xeem tiag tiag (raws li qhia hauv daim duab 1), nyob rau hauv cov nqi sib txawv, qhov ua tau zoo ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog yog qhov siab dua li ntawm lub qhov txhab-rotor asynchronous motor.In lub load npaum li cas ntawm 50% - 100%, qhov ua tau zoo ntawm 0% cov hlau nplaum ruaj khov tuaj yeem ua tau zoo dua li ntawm 0% 0% synchronous zog. qhov txhab-rotor asynchronous lub cev muaj zog, uas tuaj yeem txo cov nqi siv hluav taws xob rau kev ua haujlwm ntev ntawm kuv hoists.

Daim duab 1: Kev sib piv kev ua tau zoo ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog thiab lub qhov txhab rotor asynchronous lub cev muaj zog

2. Kev txhim kho lub zog

Thaum lub qhov txhab-rotor asynchronous lub cev muaj zog khiav, nws lub hwj chim feem ntau yog nyob nruab nrab ntawm 0.7 thiab 0.85, thiab cov khoom siv hluav taws xob ntxiv yuav tsum tau ua kom tau raws li cov kev xav tau ntawm daim phiaj.Lub zog ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog tuaj yeem siab li 0.96 lossis siab dua, ze rau 1.Qhov no yog vim cov hlau nplaum tsim los ntawm cov hlau nplaum ruaj khov rau kev ua haujlwm zoo heev thaum lub sijhawm ua haujlwm. Cov khoom siv hluav taws xob siab tsis yog tsuas yog txo cov hluav taws xob reactive lub nra ntawm daim phiaj hluav taws xob thiab txhim kho lub zog zoo ntawm daim phiaj hluav taws xob, tab sis kuj txo cov nqi hluav taws xob ntawm cov lag luam mining thiab txo cov peev nyiaj thiab kev saib xyuas cov khoom siv hluav taws xob reactive.

(3). Kev cuam tshuam rau kev ua haujlwm nyab xeeb ntawm mine hoists

1. Pib thiab braking yam ntxwv

Lub zog pib ntawm cov hlau nplaum ruaj khov synchronous lub cev muaj zog yog du thiab meej tswj tau.Thaum lub sijhawm ntawm kuv lub hoist pib, nws tuaj yeem zam teeb meem xws li hlua hlua co thiab nce hnav ntawm sheave tshwm sim los ntawm kev cuam tshuam ntau dhau thaum lub cev muaj zog pib. Nws qhov pib tam sim no me me thiab yuav tsis ua rau muaj qhov hloov pauv loj hauv daim phiaj hluav taws xob, kom ntseeg tau tias kev ua haujlwm ib txwm muaj ntawm lwm cov khoom siv hluav taws xob hauv mine.

Nyob rau hauv cov nqe lus ntawm braking, mus tas li hlau nplaum synchronous motors yuav ua ke nrog advanced vector tswj technology kom ua tau meej braking torque regulation.Piv txwv li, nyob rau hauv lub deceleration theem ntawm lub hoist, los ntawm kev tswj lub magnitude thiab theem ntawm lub stator tam sim no, lub cev muaj zog nkag mus rau lub zog tiam braking xeev, converting lub kinetic zog ntawm lub hoist mus rau hauv hluav taws xob lub zog lub zog thiab kev noj qab haus huv braking. Piv nrog rau cov txheej txheem braking ib txwm siv, txoj kev siv braking no txo ​​qhov hnav ntawm cov khoom siv sib tsoo, ua kom lub neej ntev ntawm kev ua haujlwm ntawm lub braking system, txo qhov kev pheej hmoo ntawm nres nres vim nres overheating, thiab txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm hoist braking.

2.Fault redundancy thiab txhaum kam rau ua

Qee cov hlau nplaum ruaj khov synchronous motors siv ntau theem winding tsim, xws li 6-theem ruaj khov hlau nplaum synchronous lub cev muaj zog.Thaum ib theem winding ntawm lub cev muaj zog tsis ua haujlwm, cov seem seem windings tseem tuaj yeem tuav cov haujlwm yooj yim ntawm lub cev muaj zog, tab sis cov zis hluav taws xob yuav raug txo raws li. zam lub hoist los ntawm hovering nyob rau hauv nruab nrab ntawm lub ncej vim lub cev muaj zog tsis ua hauj lwm, yog li ua kom muaj kev ruaj ntseg ntawm cov neeg ua hauj lwm thiab cov khoom siv.Ua ib tug rau-theem mus tas li hlau nplaum synchronous lub cev muaj zog raws li piv txwv li, piv txwv li hais tias ib tug ntawm cov theem windings yog qhib, raws li lub torque faib txoj kev xav ntawm lub cev muaj zog, qhov seem tsib-theem windings tseem tuaj yeem muab txog 80% ntawm cov khoom siv hluav taws xob muaj feem xyuam rau lub cev muaj zog. txaus kom tswj tau qhov ua haujlwm qeeb ntawm lub elevator thiab ua kom muaj kev nyab xeeb.
