Qauv & Txoj Cai Ua Haujlwm

Qauv: Kev tawg- pov thawj thruster + nres ncej + sab laug / sab xis nres nkawm khau + rov qab springs + pib- tshem tawm ntsuas ntsuas + kaw lub caij nplooj ntoo hlav + tus kheej-lubricating hinges.

Ua tsis tiav -Kev Ua Haujlwm Zoo:

Fais fab-on: Thruster lifts pushrod, compresses brake springs, retracts shoes (brake tso).

Fais fab-off: Thruster poob siab; rov springs thawb khau tiv thaiv nruas (brake engaged).

Qhov Zoo Tshaj Plaws

Flameproof kev nyab xeeb: Exd I daim ntawv pov thawj rau cov mines; sealed flameproof pob qij txha tiv thaiv qhov chaw ignition.

Auto- sib npaug clearance: Cov cuab yeej sib cuam tshuam tswj xyuas txawm tias khau tshem tawm, zam ib qho - ib sab lo.

Kev saib xyuas tsawg: Tus kheej-lubricating hinges (tsis xav tau lubrication); ceev -clamp liner rau hloov ceev.

ruaj khov torque: Kaw lub caij nplooj ntoos hlav raj tiv thaiv springs; torque adjustable ntawm lub caij nplooj ntoos hlav compression.

Kev ntseeg siab: Ua raws li GB6333-86, JB/T6406-2006, thiab MT912-2008; mining kev nyab xeeb cim tau ntawv pov thawj.

Daim ntawv thov

Lub hauv paus tseem ceeb: Deceleration thiab nres nres rau cov thee mine siv conveyors, hoists, thiab tsheb thauj mus los hauv av.

Secondary: Haum rau metallurgy, cov chaw nres nkoj, thiab cov khoom hnyav tuav nrog kev pheej hmoo tawg; hloov BYWZ5 brakes tib yam -mount setups.

Installation & Kho

Kev teeb tsa:

Mount rau ntawm lub hauv paus nruj; xyuas kom lub nruas concentricity (runout Tsawg dua los yog sib npaug rau 0.15 mm) thiab thruster pushrod alignment.

Siv cov ntaub ntawv pov thawj tawg- cov ntaub ntawv pov thawj thiab cov hauv av kom zoo; khaws cov nplaim hluav taws tsis huv kom huv si / tsis muaj kev puas tsuaj.

Sau thruster nrog ISO VG 32/46 hydraulic roj rau qib cim; cua los ntshav ua ntej commissioning.

Kev tu:

Txhua hnub: Tshawb xyuas cov roj thruster, cov dej ntws tawm, thiab cov suab nrov txawv txav; huv si saum npoo thiab cua ua pa.

6 lub hlis: Tshawb xyuas cov roj zoo; hloov yog degraded.

12 lub hlis: Overhaul thruster seals; tshawb xyuas lub cev muaj zog (Ntau dua lossis sib npaug ntawm 2 MΩ); txheeb xyuas flameproof sib koom qhov khoob.

Hloov cov ntaub ntawv thaum lub thickness<5 mm; never modify flameproof components.

Common Faults & Fixes

txhaum	Ua Tau	Kho
Tsis muaj zog braking	Hnav cov hnab looj tes, tawg rov qab caij nplooj ntoos hlav, xoob thruster	Hloov cov liners / caij nplooj ntoos hlav; rov qab thruster
Luag / overheating	Clearance imbalance, khau khiab, thruster to	Xyuas auto{0}}balancer; huv/lubricate nkawm khau; kho cov ntsaws ruaj ruaj
Tsis ruaj khov torque	Caij nplooj ntoos hlav qaug zog, tsis raug compression	Hloov caij nplooj ntoos hlav; hloov compression
Thruster tsis ua hauj lwm	Lub cev muaj zog thim rov qab, lim lim, impeller puas	Kho theem; hloov lim / impeller

Kev Nyab Xeeb & Kev Ua Raws Cai

Muaj ntawv pov thawj los ntawm Tuam Tshoj Mining Products Safety Approval and Certification Center (CMA).

Ua raws li GB3836.1/2-2010 nruj me ntsis rau kev kho cov nplaim taws; tsis txhob siv cov khoom seem uas tsis tau pom zoo.

Siv tsuas yog tawg- cov ntaub ntawv pov thawj cables thiab xyuas kom meej hauv av kom tsis txhob muaj hluav taws xob zoo li qub.
