简体中文 Have you ever been hurt by the noise of the factory? Or were told by the salesman when purchasing that it was "absolutely quiet", only to have it installed with a noise level of 80 decibels?The novice to choose a quiet conveyor line is afraid of three things: buy the wrong type, noise overload, and maintenance cost explosion!Today we will break up the crumbs to say - the purchase of silent conveyor line is not a metaphysics, seize the "load, noise decibel, scene" the iron triangle, avoid the pit of 90%!
First, load capacity: choose a big waste of money, choose a small repair every day
Basic question: What exactly is the "load capacity" of a silent conveyor line?
It's not just about looking at the manufacturer's labelled maximums! Got to break it down into three hard indicators:
- ultimate load-bearing: The maximum weight that the conveyor line can carry. For example, the roller line marked 4000kg, but the actual use of 20% margin, otherwise the bearing minutes strike.
- uniform load: Pressure-bearing capacity when the material is laid flat. The difference in pressure on the rollers between feeding rice bags and feeding metal parts is vast!
- shock loadThe instant impact of the material "banging" down. It is recommended to choose chain line for ores, ordinary belt line can't bear it at all.
Scenario question: what load should I choose for my workshop?
- electronic factory(Circuit boards, mobile phone cases): Light load ≤60kg → closed-eye selectionsynchronous belt lineIt's cheap and quiet (65dB or so).
- auparts factory(Engine block): Heavy load ≥1000kg → mandatorySpeed Chain LineNylon rollers + acoustic enclosure keep the noise down to 72dB.
- repository(full container): within 500kg of medium load →platenMost fragrant, 55dB less than the sound of a fridge
SOLUTION: What happens when you buy a smaller load?
The results of a factory feeding 300kg of metal parts on a belt line:
→ Belt stretch deformation, positioning error widens from ±1mm to ±5mm
→ Roller bearings are changed once a month, and maintenance is more expensive than the equipment!
remedy: Immediate retrofittingRubber-coated rollers(￥150/pc), load lift 30% and noise reduction 10dB
Second, the noise decibel: 70dB is the red line, below 60dB is considered really quiet
Basic question: How to measure the "decibel value" of a silent conveyor line?
Don't believe the manufacturer's laboratory data! The national standard GB/T 10595 stipulates:
- Measurement point location: 1 metre from equipment, 1.5 metres above ground level
- Requirements for working conditions: No-load ≤ 75dB, full-load ≤ 80dB (exceeding is regarded as noise pollution!)
- real-life exampleA speed chain is labelled as 70dB, but the actual measurement is 83dB - no deduction is made for background noise in the workshop.
Scenario question: where are the noise red lines in different industries?
| sector | noise limit | Recommended Conveyor Line Types |
|---|---|---|
| electronics laboratory | ≤55dB | Synchronous belt line + soundproof cover |
| Food Packaging Workshop | ≤65dB | Stainless steel drum line |
| automobile assembly line | ≤75dB | Double speed chain + nylon roller |
| Mining Crushing Plant | ≤80dB | Heavy duty chain line + damping layer |
Solution: How much will I be fined for exceeding the noise limit?
→ Residential area factories over 80dB: environmental protection tickets start at 50,000, but also may be suspended from production rectification
→ Workers' hearing impairment: damages + litigation costs can wipe out half a year's profits!
Noise Reduction First Aid Kit::
- Drive motor plusThree-layer sound enclosure(steel plate + rock wool + porous board), noise reduction of 15dB.
- Chain line changeNylon RollerReduced friction sound from 85dB to 72dB.
Third, scene adaptation: the environment will "kill", choose the wrong material all finished!
Basic question: what scenarios are most deadly for silent conveyor lines?
- crystal growth>100℃: Common belt aging and breaking → Must be selected.Heat-resistant glass fibre tape
- high humidity/Acid and alkaline environments: metal rusting and seizing → Recognised304 stainless steel body(Food factory just needed!)
- dusty: Bearing dust noise → UseSealed bearings + vacuum connectionof roller lines
Scenario question: how do you avoid pitfalls in specialised industries?
- food factory::
→ Don't use chain lines! The grooves hide mould, and the Health Department is a good place to look for it
→ ChangeFlat top chain plate lineThe water gun can be used to flush out the water without any stagnant water. - Electronic clean room::
→ Reject ordinary grease! Volatile contamination of the chip → ChangeSelf-lubricating silent bearings(Teflon coating)
SOLUTION: What mines will explode if the environment doesn't match?
The results of a sauce plant with 201 stainless steel drum line:
→ six months rust through the drum, acid leakage contaminated the whole batch of goods
→ One week shutdown + $1.2 million in customer claims!
Refurbishment Guide::
- Spraying the whole thing after rust removalPolytetrafluoroethylene anti-corrosion layer(¥500/m)
- Bearings replaced withCeramic SealDouble the life span of acid and alkali resistance
Fourth, the cost of traps: cheap equipment hidden "swallowed the beast"
Basic question: how do you calculate the total cost of a silent conveyor line?
Don't just look at the purchase price! Remember the formula:
Total cost = Purchase price + Electricity × 5 years + Maintenance × 3 years + Shutdown losses
→ A factory bought $700,000 of ordinary chain line on the cheap, and the result:
Electricity cost is higher than the silent model 30% (higher motor power)
2 repairs per month, with a loss of $80,000 per shutdown
Scenario question: cost comparison of the three dominant types
| typology | Purchase price (¥/m) | Electricity for 5 years | Maintenance frequency |
|---|---|---|---|
| leather belt line | 800-1500 | lower (one's head) | Change the belt once every six months |
| Speed Chain Line | 2000-3500 | middle | 1 annual inspection of 1 chain |
| platen | 1200-2500 | extremely low | 2 year bearing change |
Solution: How to remedy an already expensive purchase?
three-step stop-loss method::
- lower electricity tariffs: Add AI speed control system (¥ 50,000), ultra-noise automatic speed reduction, electricity costs save 25%
- extend lifePolyurethane（￥50/pcs）, wear-resistant 3 times.
- deactivateSignaturepay per callMaintenance contract - $30,000 for failure to attend for 4 hours!
Fifth, intelligent plus: mute ≠ mute, will alarm is reliable
Basic question: What is an "active noise cancellation" conveyor line?
Not just muffling the noise with soundproof enclosures, but also being proactive:
- voiceprint monitoring: Sensor listens for bearing noise, warns of failure 3 days in advance
- AI speed control: Automatically reduces belt speed when excessive material impact noise is detected.
- Self-levelling rollers: Hydraulic automatic levelling when vibration exceeds the standard, avoiding resonance roar
Scenario question: which plants must be on the smart model?
- 24-hour continuous productionof the workshop: unexpected downtime 1 hour loss of 500,000 up
- populated areaNight Shift FactoryComplaints about the environmental protection will come.
- Precision assembly line: 0.1mm vibration causes yield to plummet
Solution: How to turn an ordinary wire into a smart one at low cost?
→ retrofittingIoT diagnostic kit(¥800/unit):
Real-time monitoring of decibel, vibration, temperature, exceeding the standard automatically send an emergency text message
After the retrofit at an electronics factory, downtime was reduced from an annual average of 36 hours to 4 hours!
Editor's point: Silence is a productivity, not a luxury!
After ten years of designing production lines, I am most annoyed to hear people say, "Why do you want to save money on noise?Silent conveyor line is expensive for the unit price, save the total account::
- ¥ 500,000 silent times the speed of the chain than ¥ 300,000 ordinary models - 5 years to save 280,000 electricity + maintenance costs
- Workers take off the earplugs, the efficiency of 15% is equal to pick up 10 labourers for nothing!
- Zero complaints about factories in residential areas, one pass in EPA annual inspection
Next time you make a purchase, putNoise fines, production stoppage losses, workers' compensationSpread out the maths - you'll find that silencing equipment is actually here to make money!
