简体中文 You must have muttered in your mind, "Five-year warranty? Bullshit! Conveyor line every day to carry goods, bearings are grinding smoke, manufacturers dare to guarantee five years?" To be honest, I also muttered when I first heard - until I saw a case: a food factory used five years of stainless steel conveying line, remove the cover to see that the chain is shiny like a new installation! Today we have to break up the crumbs to say, the manufacturer in the end to make what trick.
First, the material is hard work: not all stainless steel is called "304″.
Core problem: Why do ordinary conveyor lines rust after two years of use?
The answer lies in the materials! The manufacturers who really carry the build will do so:
- Stainless Steel for Real::
General plant "201 stainless steel" (containing nickel 4%).Conscientious factory must use 304 stainless steel(Containing more than 8% of nickel).
How do I look at it? Let the manufacturer provideMaterial Spectrum Test Report--It's the same as testing the purity of gold! - The chain dares to trace its origins.::
A large factory directly to the chain engraved steel seal "GERMANY IWIS", scanning code can check the production batch, more stringent than the milk powder traceability. - Bearing seal double insurance::
Plain bearings braced to IP54 dust protection (against a little light rain).Five year warranty dare on IP65 rated sealing-Spray alcohol sterilisation doesn't even come with water in it.
The white man avoiding the pitDon't believe that "all stainless steel", the contract should be written "304 material, nickel content ≥ 8%"!
Second, the design of the mystery: 120% overload test is the hard truth
The core problem: the drawings are quite beautiful, why do they lie down once used?
This is like talking on paper! Reliable manufacturers must be "dynamic verification of the three axes":
- Simulation of extreme scenarios
- Conveyor line for automotive parts factory: Designed to carry 1 tonne?Measured pressure of 1.2 tonnes of iron to run for 24 hours
- Northeast Freezer Dedicated Line.-30°C power-on testTo prevent cold brittleness of bearings (Southern factories don't even think of this step).
- Intelligent anti-dumbing pre-built
a danger spot General plant programme Five-year factory maintenance programme plug It's up to the workers to keep an eye on it. Automatic shutdown of laser sensors Chain breaks after-the-fact maintenance Adding a tension monitor warning - Maintenance access reservation::
Rack side panel openingQuick release window(The bolt opens with a twist.) Changing bearings is as easy as opening a fridge door.
lesson learnt through blood and tears: An electronic factory saved the test fee, the result of the conveyor line jammed and burned the motor, shut down production for three days and lost a million dollars!
Third, the manufacture of more serious: workshop hidden "perverted quality inspector"
Core issue: Why does the quality of the same drawings vary so much?
The key lies in the production link of the "spirit of death"! Five-year warranty manufacturers must be these tawdry operation:
- Welding to play with micro-sculpture::
Ordinary factory welds and grinds them flat.High-end factories use industrial endoscopes to see welds--Porosity more than 0.5mm is considered as scrap. - Precision down to the hairline::
make a copy of
Sprocket pitch error: ≤0.03mm (one-third of a hair) Parallelism of roller: ≤0.2mm per metre. - Assembled like Lego::
After each section.Shoot 360° video for archivingI've got a record of how many turns the screws were turned.
The truth about the industry: The factory that dares to make a five-year warranty, the workshop quality inspector is stricter than the invigilator of the college entrance examination!
IV. Testing for life: 72-hour "devil's training camp"
The core problem: empty turn quite skilful, on the goods out of trouble?
The most ruthless thing a five-year warranty manufacturer can do is the testing part:
- gradient torture
30% load run for 8 hours → 80% load run for 24 hours →120% Extreme Load Continuous Rotation 48 Hours - Emergency situation simulation
- Sudden power cuts 10 times: watchDoes the PLC programme lose data
- Splashing oil and then stopping sharply: a testBrake Pad Slip Rate(below 5% to pass)
- Running Tests with Sickness::
Remove a screw on purpose and seeCan the fault diagnostic system alarm in 3 seconds- - It's like a human immunity test!
what one sees with one's own eyes: A factory test room machine roar around the clock, do not know that the thought of opening a hardware processing plant it.
Fifth, the maintenance of black technology: mobile phones can be a "perspective eyes"
Core issue: say 24 hours to the door, but end up waiting for three days?
The factories that play with five-year warranties these days are long past relying on manpower:
- The equipment will "self-check"::
Bearing temperature over 70°C?Automatically sends text messages to the plant manager's mobile phone(Faster than staff reporting) - Raising "digital stand-ins" on the cloud::
Your workshop conveyor line'sVibration frequency/current fluctuationThe model is synchronised to the cloud in real time, and faults are predicted in advance. - Lightning delivery of accessories.::
You alarmed the machine in Dongguan.Foshan warehouse automatic packing accessories--Drones can even deliver screws!
destabilise perceptionsLast year, a logistics warehouse conveyor line collapsed, the engineer did not arrive, the first remote lock the faulty module, the other segments run as usual!
Personal opinion time: five year warranty really isn't a gimmick.
Seen too many factories for the price cut corners, the result of after-sales cost is ten times the cost of materials! On the contrary, dare to promise a long warranty factory, often put the effort in front - just like planting trees, deep roots in order to carry the wind and rain. Next time you meet "my home warranty five years", ask him directly four sentences:
- "Can I watch the load test video?"(No video is bragging)
- "How far away is the spare parts store?"(Over 200 kilometres equals no warranty)
- "Is there an extra charge for IoT access?"(Anyone who charges a fee is a hooligan.)
- "Default to pay for stoppage of production losses?"(Clauses that you don't dare to write are paper tigers)
Remember ah friends, the conveyor line is the artery of the production line, would rather spend more than 30,000 to buy peace of mind, do not save five thousand every day to repair!
