简体中文 Do you always wonder why other people's conveyor belts last five years and yours squeaks and rattles after only one year? Don't worry! Today we will take you to dismantle this set ofMaintenance tips for industrial blood vessels--Don't need to know electromechanical principles, a novice can get started immediately!
I. Running out of steam? Don't kick the machine yet!
Conveyor belt run-off is the number one killer, butThere is a golden mnemonic for adjusting bias: "Run tight, not loose, adjust back, not forward."The first thing I did was to take a look at the conveyor belts. To cite a real case: a logistics warehouse conveyor belt every day, the teacher only did three things:
- Take a tape measure and measure the parallelism of the rollers--The error is more than 0.5mm/m, immediately adjust the bearing seat.
- Scraping off caked cinders from the redirection drums(Sticky material makes the rollers "big" and "small".)
- Add shims to the roller frame to fine-tune the 2° angle.--Saved $30,000 over a new belt.
👉 Remember this trick: whichever way the belt is deflected, put the rollers there!Push a little in the direction of the belt.Don't exceed 4°!
Second, tension control: loose slippage, tight life folding
The most common mistake newbies make - straining the conveyor belt like a drum surface!The correct tension should be like pressing a spring: 10-15mm is enough.. Teach you a dirt method:
- Pressing on the middle of the belt during shutdownThe sinking volume is ≈ 1.5% of the bandwidth.
- high speed line(>40m/s) with laser tensiometer, error <5%
- A must for lazy people: Quarterly checks, summer tuning loose 2% (heat expansion and contraction ah brother!)
Sudden skidding? Check these three places first:
- Is the drive roller glued with a layer of oil (take theAlcohol cotton pad rub! Don't use water.)
- Tensioning counterweights are stuck (especially in mining environments)
- Belt interface open glue (fingernail picking down the edge, open seam more than 3mm hurry to repair)
Third, cleaning and maintenance: do not wait for the accumulation of grey into sandpaper!
A bloody lesson for food factories: A certain yoghurt line changed its belt once every three months due to corrosion from milk stains! Later changed to:
- High-pressure water jetting of drum seams every 4 hours(Water temperature <60°C)
- Addition of rotating wire brushes in dusty areas-Wear rate straight down 40%
- The Pharmaceutical Factory's Essential Techniques: Silicone rollers + food-grade lubricant (regular butter contaminates medicines!)
⚠️ Deadly Taboo:
- Acid and alkali materials(e.g. for fertilisers) corrosion-resistant rubber belts must be used.
- High temperature line above 80°CGotta switch to neoprene (regular tape turns to playdough when it gets hot).
- cleanMust be dried thoroughly! Moisture is the culprit of wire rope rusting
IV. Emergency response to sudden stoppages
The production line suddenly stopped in the middle of the night? Don't panic! Check in this order:
- Touching the motor casing-Hot? Overloaded!
- Listen to the drum rattle--The "clunking" sound may be a broken bearing.
- Look at the control cabinet indicator lights::
- Red light flashing.The photoelectric sensors are dusty.(Accounting for malfunction 70%!)
- Yellow light on.Inverter overload alarm(Turns down start-up acceleration)
- The ultimate life-saving move.provisionQuick Repair Tape(Cold gluing on site in 20 minutes)
V. Spare parts management: small money not spent, big money suffers
A private list for veteran mining drivers::
| mandatory replacement | replacement cycle | Money Saving Tips |
|---|---|---|
| Sweeper Rubber Sheet | 2 months | DIY Old Tyre Cutting |
| Buffer rollers | 1 year | Get the nylon core (more impact resistant than metal) |
| Roller Covering | 3 years | Partial repair saves 60% over full replacement |
👉Key data: Roller stock = total quantity x 15% (e.g. 100 rollers ready for 15)
Conveyor belts are not consumables to be repaired, but assets that become more valuable with age. When I saw the family that insisted onDo weekly deflection testsof the car factory - haven't changed the main conveyor line in eight years and saved enough money to buy a forklift when...genuinely think that theMaintenance is not a cost, it's a solid investmentOh, my God! Next time you hear a conveyor humming, don't be annoyed, it's the machine saying "Thanks, mate".
