Regarding the installation of plate heat exchangers after cleaning
Thread Content
When people disassemble and clean plate heat exchangers, what tools do they use to reinstall them? At my previous workplace, we used self-made wrenches for this task; it took a very long time and was also physically exhausting. Later, I asked a mechanic to create a bracket for lifting the plate heat exchanger, using a jack to lift it. The first bracket made wasn’t strong enough, and it bent. The maintenance worker told me that using a hand chain hoist is also a good option. I wonder what tools others use to remove and replace the panels?
There are specialized tools; you can ask the gasket manufacturer for them. If it involves heat exchange with concentrated acid, it is recommended that you avoid doing this. This post was last edited by in the blink of an eye on 2009-4-19 22:46.]
Dude, why do you have to take it apart and wash it? There’s no need to disassemble it; I’ve washed hundreds of heat exchangers like this, and none of them have needed to be taken apart! Let me wash it; I promise I won’t break it! Guaranteed to be clean and safe for equipment! Just use a pump for circulation – it’s hassle-free and saves effort! The device gets damaged every time it’s disassembled! We specialize in cleaning equipment; you can send me a message to discuss in detail.
Aren’t there bolts? Just unscrew it directly, and remove the pieces one by one – it’s very simple
Aren’t there bolts? Just unscrew it directly and remove the pieces one by one. There are many things to be careful about inside, buddy. Take your time and be careful with the seal :) Good luck to you
There are special cleaning solutions, and it also requires a professional to disassemble it; otherwise, it’s not easy to install
Yes, we manufacture plate heat exchangers using 93 acid. Back then, in order to increase production and the heat exchange area, what was done was to increase the number of plates; they were all taken apart by simply unscrewing the fixing bolts, each plate was removed, cleaned, and then reassembled. As a precaution, all gaskets were replaced. (Gaskets are also very expensive.)
The most convenient way to clean plate exchangers is to alternate between acid water and normal water; this should be taken into account during the design phase, with regular switching, which yields very good results
Plate heat exchangers really don’t need to be taken apart for cleaning. Cleaning them involves using a brush, and with plates that are less than one millimeter thick, brushing them several times can create problems. By making slight modifications to the acid and water pipelines, it’s possible to use acid for cleaning. But if you really decide to take them apart, you need to prepare gaskets in advance, so as not to regret not having them available for replacement during installation. Actually, installation and removal are very simple. No special tools are needed either
If it’s an acid-cooling type, once it’s disassembled, it’s very risky not to replace the gasket.
Our factory uses acidic water to clean heat exchangers, and the results are excellent; it has no adverse effect on the heat exchangers.
