简体中文 Why do you always step on the pitfalls of buying a double-deck doubler chain? Space saving 40% but failing all the time?
My friend, have you also encountered this kind of suffocating thing - spend a lot of money to buy a double-double speed chain, but the result is three days downtime for maintenance? Don't panic! To be frank.The problem with the 90% is that the maintenance requirements were not calibrated at the time of purchase.The first is a real case. Give a real case: Dongguan electronics factory last year to save 30% workshop area, the results of the chain three months on the wear and tear deformation, why? Because they chose ordinary carbon steel chain but used in the 24-hour operation of the production line. Remember.Maintenance costs are a matter of life and death at the point of purchase!
Ask yourself: Is choosing a chain like choosing running shoes? Triple or 2.5x?
Depends on the "intensity" of your exercise!
- lightweight(Electronic assembly): Engineering plastic roller chain, silent and anti-static, running 10,000 pieces per hour without panting.
- heavyweight(Car engine): Stainless steel chain + wide body chain plate, carrying 800kg like a school bag.
- special forces soldier(Food Cold Chain): Low temperature resistant chain with sealed bearings, -25℃ still silky smooth.
Can't read the parameter table? Three sets of numbers determine life and death!
Keep an eye on these three groups of numbers when purchasing, and you won't lose out:
- WA value(Weight of conveyor per metre) = (Weight of workpiece + weight of pallet)/distance travelled by pallet
For example, if you transport a computer motherboard: workpiece 2kg + pallet 1kg, move 0.5m, WA=6kg/m. - Allowable tension T> Actual tension, remember the formula:
T=G/1000M x (Hw+Cw)L1-fc + Aw-L2-fa + ... (Don't be confused! Let the manufacturer calculate it for you) - Chain speed: electronic industry soared to 15m/min, heavy industry recommended ≤ 5m/min
| sector | lethal parameter | Rollover case warning |
|---|---|---|
| Photovoltaic glass | Crushing rate＜0.05% | A factory uses the wrong guide rails and loses millions of dollars a month. |
| Medical equipment | Vibration offset ≤0.1mm | Without the pneumatic shock absorber, the yield rate plummeted. |
| Airport Logistics | Wrong Marks ↓82% | RFID isn't connected. There's a mountain of luggage. |
Maintenance done right = picking up a new unit for nothing!
Last week I was nattering with old Li from the Suzhou factory, and he was so proud: "I've had this chain for five years, and the failure rate is lower than a new machine!" The secret is hidden in theFour Steps to Lazy MaintenanceMile:
- inspect three times a day(done 5 minutes before the end of the day):
- Feel the chain temperature (over 60 ℃ hurry to check the lubrication)
- Listen for unusual noises (squeaks = lack of oil, clunks = loose tensioning)
- Cleaning impurities (take a small brush and sweep track debris)
- Date of the Month(Save $30,000 in repairs in 2 hours):
- Give the chain a "spa": lubricate with lithium grease, don't fool around with oil!
- Tighten the "waistband": Tensioning device adjusted to the drop <5mm
- annual round of health care::
- Changing the "blood" (lubricant) in the gearbox.
- "Dialysing" the rollers (ultrasonic cleaning)
The upper and lower levels of the "break-up"? Three strokes of first aid!
Ask yourself: Is the top running fast and the bottom dragging its feet?
It's most likely a "nervous disorder"! Try this:
- physiotherapy: Coaxial drive replaces split motor, speed difference becomes 0 in seconds
- electro-acupuncture (medicine): Add synchronisation modules to PLCs for as little as $8,000!
- combine Chinese and Western medicine: RFID positioning + pneumatic jacking, pallet docking error <1mm
Shanghai Auto Parts Factory Tested: Downtime reduced from 8 hours to 20 minutes per week!
If you ask me.Buying a double-decker chain is like getting a wife - you can't just look at the face (parameters), you have to know how to get along (maintenance).. Those bosses who complain daily about the pettiness of their equipment are 80% not getting it.Good equipment is bred, not forced.I'm not sure I can do that. Next time you see a shop steward chasing a chain with a spanner, remember to flip him off with this, "Dude, grease works better than a spanner!"
