Are you having a headache in choosing a supplier of speed chain? The quotes range from 50,000 to 500,000, and all of them say they are "professional and reliable", but the result is that after installation, either the chain runs out of shape or the motor burns out? Today directly on the dry goods, teach you to see through the supplier set, choose the right team to save heart and money!
First, the first pick manufacturers of the old bottom, do not believe the brochures
Checking physical factories over 5 years old is the bottom line
Don't touch the "skin bag company" without its own workshop! The real reliable supplier, dare to let you directly into the production workshop to see semi-finished products - focus on whether the welding seam is uniform, track cutting accuracy enough 0.1mm. an electronics factory gullible showroom samples of the machine, the actual installation of the track seams can be stuffed into the nail cap, returned to the skin for three months.
Case video to be with running parameters
Have sales send a live video of a similar project that must be included:
- Motor current value when conveying a full load of work plates (fluctuations >5% indicate design defects)
- Noise measurement by mobile phone (direct elimination if >75dB at 1m from equipment)
- Emergency stop response speed(Violation of national standards if >0.5 seconds)
II. Technical programmes hide the devil's details
Be wary of "one-size-fits-all" design solutions
It is not reliable to say that "any product can be conveyed"! Precision electronics and automotive parts require very different speed chains:
Product Type | Core Points of Difference | pitfall case |
---|---|---|
electronic component | Anti-static + micro-vibration control | A factory did not do grounding, chip breakdown rate soared 30% |
Automotive parts and components | Heavy Duty Impact Resistant Structures | Legs less than 8mm thick, deformed in three months |
Food packaging | Food grade lubricant tank | Fined 100,000 for using industrial grease |
Tensioner configuration exposes professionalism
The key item that newbies are most likely to overlook!Manual tensioners are cheaper than automatic ones 40%The automatic type must be chosen for production lines with large load variations - a power plant used the manual model to save money, and the chain broke twice in three days during the peak season when the speed was increased.
Third, the quotation in the 3 invisible pit
The word game of "free installation"
Waiting to add money for those four items not spelled out clearly in the contract:
- Grinding fee for excessively poor floor levelling (>3mm)
- Overtime in excess of an 8-hour working day
- air interface modification fee(80% is a separate charge)
- Surcharge for construction on weekends/holidays
Warranty Terms and Conditions
The poorest warranty ever seen says: "Chain breakage is human damage" - professional contracts must be clear:
- 2-year warranty on core components (motor/guide/chain)
- 48-hour fault response
- Wear parts (rollers/bearings) guaranteed for 6 months
Fourth, the installation site to keep an eye on the 3 places
First day mandatory track laser levelling
The foot is not levelled directly call off! With a 2-metre ruler test, the gap > 0.5mm must be reworked on site. An auto parts factory supervisors did not keep an eye on, the result of the whole line tilted to cause the collective "drift" of the work plate.
Motor alignment without the double meter method is a trick.
Take the laser alignment instrument with a percentage table, radial deviation > 0.08mm immediately require adjustment - do not believe that the "test machine and then adjust" nonsense! A medical equipment factory after the compromise, the motor burnt out two sets in six months.
Chain pre-stretching not done = chronic suicide
Tensioner allowance <10mmThe supplier of the rushed to change! The new chain must be pre-stretched for 30 minutes to eliminate 0.3% elongation, otherwise the thermal expansion and contraction is directly taut.
V. Soul question: Is your team reliable?
Q: How do I verify the experience of the installation team?
A: To be constructed in the near futureWatermarked Time Photos! Highlights to watch:
- Close-up of track splices (poor craftsmanship with lots of burrs)
- Electrical control cabinet wiring (not necessary for crooked wire number labels)
- Worker safety equipment (direct pass without goggles)
Q: What about after-sales ripoffs?
A: The contract adds these two articles:
- Failure to shut down for more than 24 hours, according to the daily production value of the loss of compensation
- Distance to spare parts store ≤ 200 km(Ensure 4-hour availability)
Q: Do small factories really save more money than big brands?
A: Just do a three-year total and you'll see:
cost item | Regular suppliers | small workshop (of artisan) |
---|---|---|
installation cost | 200,000 | 150,000 |
Maintenance costs for two years | ≤30,000 | ≥ 120,000 (including shutdown losses) |
Comprehensive cost | 230,000 | 270,000+ |
I do this line for ten years to see more: in order to save 50,000 installation fee to choose a miscellaneous factory, the last light repair equipment will cost more than 200,000 yuan! Remember.It's more important to see the supplier's workshop than the showroom, and it's more important to check the word of mouth of regular customers than to listen to sales bragging.The most reliable partners are those who dare to tell the story of their failures. Those who dare to lay out their failures as well are often the most reliable partners.
