Hello, everyone.
This is Enta.
Submersible pumps (hereinafter referred to as "sub-pumps") tend to stop working quite often, don't they?
Is it working exactly as specified?
People tend to think that Suipon breaks down suddenly, but that’s actually not always the case.
Since the cause is often related to how the device is used, I’ll briefly list the common causes of breakdowns and the parts to check.
1. Broken Captia wire
First of all, the most common failure is a broken Captia cable.
Some people pull on the power cord (cable) while placing the unit into a water tank or similar container.
This won't work.
The captiar is a live wire, so please handle it with care.
What's more, even the 100V models of the Suipon are fairly heavy, which makes them more prone to wire breakage.
When inserting the suction cup, be sure to tie the rope to the handle before use.
2. Debris in the impeller
Debris often accumulates inside the impeller.
There were times when the fishing line got tangled.
It's a bit of a hassle because you have to take apart the bottom of the submersible pump to remove the impeller, but if you notice that the suction capacity is low even though power is being supplied, please check it.
3. Impeller damage or wear
This is another common behavior, but water snakes also suck up muddy water and the like.
As a result, the impeller wears down, reducing the water flow—or, in the worst case, causing it to stop drawing in water altogether.
This impeller is a 200V high-head type.
It's become too round and thin.
I replaced it because the water level was low as a result.
I forgot to buy a brand-new one, so I can't compare them, lol
Some 100V models also feature impellers made of rubber or plastic.
If it stops drawing in air, I recommend checking the impeller.
4. No oil
There's oil in the Suipon, too.
If a seal breaks and oil leaks, allowing water to get inside, it can cause a short circuit and make the unit stop working, so it would be good to check those areas as well.
5. It can burn even when running empty
The Suipon is designed so that the heat generated during operation is dissipated by water.
If the unit runs dry—with no water in the tank—and starts generating heat, the internal components will overheat and burn out.
The golden rule for Suipon is to stay in the water!
6. Bonus (This Is Handy)
Since anchor and slope contractors like us use cam locks a lot, we’ve also made the mouth of the suction cup a cam lock.
Actually, since most of the Suipon’s mouth is made of aluminum, you can weld an aluminum cam lock onto it right away.
With this, you can install the cam lock in one go.
Welding aluminum to steel can be quite challenging, so we recommend using the same material for the installation whenever possible.
Although Suipon rarely breaks, it’s important to inspect it regularly because repairs are often needed quite urgently when it does break.
If it doesn't work, check the parts I pointed out this time, and if that doesn't fix it, it's time for an overhaul.
A while back, one of our employees—let’s call him Ba○—actually stuck his head in a bowl of cement slurry and just left it there lol
Even if you had to do that in an emergency, you could have just washed the inside thoroughly—but instead, you just let it harden like that...
Well, I had it overhauled and I'm still using it, lol.
If you inspect machinery thoroughly, it will run reliably.
You don't realize how important maintenance is until something stops working.
I’m not saying you have to do this every day, but if you can at least inspect the equipment at the start of a shift, about halfway through, and at the end (to prepare for the next shift), I think it will be easier to spot early signs of a malfunction.
See you later.
