简体中文 Hey, are you staring at a pile of doubler chain parts? Thinking, "If this thing goes on crooked, will it all fall apart?" Don't panic! Today we're gonna walk you through the installation process in the most down-to-earth way possible--7 Key Steps to Become a Teacher! 👇
📦 A, before the start of the preparation: do not rush, first disc clear these!
Ask yourself: what happens when you start without all the tools?
A: Light rework and reinstallation, or equipment scrap! Look at these bloody lessons:
- List of tools: Digital torque spanner (locking screws to prevent loosening)🔧, laser level (error ≤ 0.5mm/m), tensiometer (to measure chain tightness)
- Material inspection: Chain length toleranceMust be within ±0.5%The track seams take 0.05mm plug ruler card - can't be inserted to be qualified!
- Hard site specifications: Ground with a 2-metre measuring tape, gap > 3mm? Immediately sanding! Power supplyMust be independently leakproof 380V±5%Don't wait for the smoke to come out before you regret it.
🏗️ Second, the foundation is built: if the foundation is crooked by 1mm, the life of the chain is half a year less!
Core motto: Level! Solid! Load-bearing enough!
- Concrete foundation: Section steel frame erected, levelling errorWithin 1mm/m(Oversized? Add shock pads!)
- positioning secret:: Axis marking by laser markers -Don't trust the eyeballs.! That's where most of the equipment goes astray.
- Load bearing testI'll tell you what I'll tell you.When it's empty, there are two strong men on it.What's that? A little wobble? Hurry up and reinforce it!
⛓️ Third, chain installation: 90% failures are due to this step is not done correctly!
Ask yourself: how tight should the chain be? What should I do if the chain is loose and jumps, or if it's tight and breaks?
🔥Here's the answer.::
- Don't go in the opposite direction.! The chain arrow points to the drive wheel, it seizes up if you put it on backwards!
- Golden value of tension: pulling with a tensiometer.Up to 1.5~2 times the weight of the chain.(Example: 10kg chain with at least 15kg pull)
- Pre-stretching against deformation: on20% Super Work TensionPull for 30 minutes! Don't be lazy or you'll stretch in 6 months!
⚡ Fourth, drive system assembly: motor is not right? Wait for the dismantling of the machine back to repair!
experience acquired through blood and tears: Motors and gearboxesAlignment deviation >0.08mmWhat? Bearings must be scrapped in six months!
- a godsend in the middle (of a fight, a war etc): Dual-meter method of calibration (laser aligner for the handicapped)
- Sprocket Hidden Test Points: Dentifrice powder, contact rate＞80%It's only a pass - otherwise the chain clicks!
- Motor Steering Test:.No-load spotting!If you turn it the other way round, switch the wires immediately, don't wait until you burn the controller before you cry.
🛠️ V. Safety and security: never make do with life-preserving devices!
Government inspections don't pass muster? The whole assembly line is shut down! Remember these two orders:
- emergency stop button: One per 6 metres ❗ Response time<0.5 seconds(Timeout? Change the switch!)
- protective netting: Mesh ≤ 8mm (GB23821 mandatory standards), fingers can not be reached into the only safety
Tell me a true story.: A factory omits protective netting, employees cuffs rolled into the chain - lost 800,000 yuan and stopped production for half a month!
🔧 Six, commissioning and operation: listen to the sound to identify faults, the old drivers are doing so
Staged testing to avoid the three main minefields::
| point | Required items | Qualifying standards |
|---|---|---|
| unladen | Startup acceleration | >8 seconds.From 0 to maximum speed |
| static (in a signal) | 1 metre away≤72dB(≈talking out loud) | |
| Load 30% → 100% | Motor current fluctuation | <±5%⚡ |
| Chain temperature rise | ≤35°C(hand can touch for 3 seconds without burning) |
Rattle Diagnostic Guide::
- (onom.) clunk→ Sprocket teeth not aligned
- hum resonance (physics)→ Bracket not locked
- sledge→ Lubrication oil is missing!Must be food grade! Molybdenum disulphide? Prohibited!
🎯 VII. Acceptance of commissioning: you think you're done after the installation?
Exclusive production recipe::
"Three Checks and Four Looks" to prevent rollovers::
- surname Zhaposition accuracy: Workpiece plate over stopper, error > 0.5mm? Adjust cylinder stroke!
- regard asChain droop: Span 2%-3% is the golden value (Example: 1 metre span sag 20-30mm)
- conjectureemergency response: Can't stop within 0.5 seconds of tapping the button?Stopping production to rectify the situation!
💡 And finally, something heartfelt.
After more than ten years of installation, I have seen too many people fall into the"Just about."Up--
"1mm difference in foundation?"→ After six months the chain ran out and wore out, and a replacement chain was enough to do the foundation three times!
"Tension by feel?"→ chains with excessive tension.Motor Load Spike 40%⚡ and pay over a hundred thousand dollars more for electricity!
Remember that brothers.Precision is money, safety is life! Follow these 7 steps to the death of the standard and the life of the equipmentGuaranteed 3-year extension! 🚀
