Ki gwosè prentan mwen bezwen pou pòt garaj mwen an?

Prentan pòt garaj ou a kase, ak pòt la ekstrèmman lou. Ou bezwen kòmande yon ranplasman, but the wrong size could damage your door or be dangerously unsafe.

Pou jwenn gwosè prentan ki kòrèk la, ou dwe jwenn twa mezi nan ansyen ou, prentan kase: dyamèt fil la, dyamèt anndan bobin la, ak longè an jeneral nan sezon prentan an. Mezi sa yo, along with the door's weight, detèmine pouvwa a leve obligatwa.

Nan ane mwen yo nan manifakti sous dlo, the biggest problems always come from incorrect sizing. Li pa sèlman sou fè pòt la monte ak desann. A spring that's too strong will make the door hard to close and can damage the top panel. A spring that's too weak will burn out your electric opener in a matter of months. Presizyon se tout bagay. Anvan ou menm panse sou kòmande yon pati, you have to become an expert at measuring what you already have. Let's walk through exactly how it's done.

How Do You Correctly Measure a Torsion Spring?

The broken spring is in front of you, but how do you get accurate numbers? A small mistake in your measurement can lead to ordering a completely wrong part, wasting time and money.

Premye, ensure the door is closed and the opener is unplugged. Lè sa a, measure the wire diameter, dyamèt anndan an, ak la overall length[^1] of the coils of one of the broken pieces. You also need to determine the direksyon van[^2] (left or right-hand wind).

I can't stress this enough: measurements must be exact. I once had a new technician in our quality lab who was off by a tiny fraction of an inch on a wire diameter measurement. He approved a whole batch of springs based on that mistake. We had to scrap the entire order because we knew they wouldn't balance the customer's doors correctly. A tiny error on a small part can cause a huge problem in the final system. The same is true for your garage door. Taking your time to get these four details right is the most important step in the entire process.

To order the right spring, you need four pieces of information. For safety, always measure with the springs completely unwound (no tansyon[^3]).

• 1. Dyamèt fil: This is the thickness of the spring wire itself. It can be hard to measure a single wire accurately with a tape measure. The best way is to measure 10 coils and divide that number by 10. Pou egzanp, if 10 coils measure 2.5 pous, your dyamèt fil[^4] se 0.250 pous.
• 2. Dyamèt anndan an: This is the diameter of the opening in the center of the spring. It is usually a standard size, tankou 1.75 pous oswa 2 pous. You can measure this straight across the opening.
• 3. Longè an jeneral: Measure the length of the spring from one end of the coils to the other. Do not include the winding cones on the ends in this measurement.
• 4. Direksyon van: Gade nan fen sezon prentan an. If the end of the wire points up to the right, it is a right-hand wind. If it points to the left, it is a left-hand wind. Pifò pòt yo gen youn nan chak.

What if the Old Spring is Missing or Was the Wrong Size?

The old spring is gone, or you suspect it was wrong because the door never worked right. Now you have nothing to measure. Guessing the size is a recipe for disaster.

If there is no spring to measure, you must determine the correct size by weighing the garage door. This involves using scales to find the door's exact weight, which is then used in a formula with door height and drum size to calculate the required spring lift.

This is the point where I strongly advise calling a professional. We have supplied springs for custom door manufacturers who need a precise counterbalance for a new design. The first thing their engineers do is calculate the exact weight of the door panel. Soti nan la, we can determine the "Inch Pounds Per Turn" oswa IPPT[^5], which is the technical term for the spring's lifting power. It's a calculation that also involves the radius of the cable drums and the height of the door. Yon teknisyen pwofesyonèl ka peze pòt ou san danje epi li gen tablo yo konvèti pwa sa a nan gwosè sezon prentan pafè a.

Kalkile asansè ki nesesè yo

When you can't measure, ou gen pou kalkile de grafouyen.

• Pwa Pòt se wa: Objektif la tout antye nan sezon prentan an se fè yon pòt lou santi yon pwa. Yon pòt garaj estanda de machin ka peze sou 300 liv. Prentan an dwe gwosè pou kontrekare pwa espesifik sa a.
• Wòl tanbou ak wotè: Gwosè a nan tanbou yo kab (pouli yo câbles leve yo vlope alantou) ak wotè pòt la tou afekte kalkil la. Pi gwo tanbou mande pou yon sezon prentan pi fò pou bay menm kantite asansè. Pòt pi wo mande pou sezon prentan an kenbe li tansyon[^3] through more turns.
• IPPT[^5] Kalkil: Professionals use these factors (weight, gwosè tanbou, wotè pòt la) to calculate the required IPPT[^5]. Every spring is rated for a specific IPPT[^5]. This ensures the new spring is a perfect match for the door's physics, not just a copy of a potentially incorrect old part.

Does Upgrading to a High-Cycle Spring Change the Size?

Your springs seem to break every few years. You want a longer-lasting option but worry a different spring won't fit. Will an "upgraded" spring be the same size as the original?

Non, a high-cycle spring will not be the same size. To achieve a longer life, the spring must be made from a slightly thicker wire and will be noticeably longer. This design reduces the stress on the steel with each use, dramatically increasing its lifespan.

Kòm yon manifakti, sa a se kote nou ajoute plis valè pou kliyan pwofesyonèl nou yo. Yo souvan mande sous dlo pou pwopriyete komèsyal ki bezwen dire pou 50,000 cycles, pa estanda a 10,000. We don't just use a magical type of steel; nou re-enjenyè sezon prentan an. Nou itilize yon dyamèt fil yon ti kras pi gwo epi ajoute plis bobin, ki fè sezon prentan an pi long. Nouvo konsepsyon sa a bay egzak menm pouvwa leve (IPPT[^5]) kòm orijinal la, men li fè sa ak mwens estrès sou materyèl la. Mwens estrès vle di yon lavi ki pi long. Kle a se ke la pèfòmans se idantik, men la dimansyon fizik yo yo diferan.

Jeni pou yon lavi ki pi long

Amelyore se sou diminye estrès.

• Estrès ak lavi sik: Chak fwa pòt ou ouvri epi fèmen, fil prentan an flechi, kreye estrès. Apre yon tan, estrès sa a lakòz metal la fatig ak evantyèlman kraze. A standard spring is designed to handle this for about 10,000 cycles.
• The High-Cycle Solution: By using a longer spring made of a slightly thicker wire, we can produce the same lifting force with less work. The longer body distributes the stress over more material. This lower operating stress means the spring can withstand many more cycles before reaching its fatigue limit. A properly engineered high-cycle spring can last 25,000, 50,000, or even 100,000 cycles.
