Cooling measures for solid pumps
Thread Content
As stated in the title: The temperature of the cylinder part of the solid pump used for transporting coal powder is too high, and heat exchange is required to reduce this temperature. Requirements are as follows: 1. It must not be welded to the surrounding structure; 2. Water must come into direct contact with the cylinder. What should I do? Seeking advice
Apply 25-mm pipes for circulating water or chilled water to the cylinder wall, then insulate it to also secure the pipes.
I wonder if it’s possible to use the principle of heat-insulating pumps to create a pump head with a jacket, and then use cold water for circulation.
Confused by the title: Solid pump? I was still thinking that pump bodies are all solid, right? Is there any liquid too? Only after reading the content did I realize that it was because the pump body overheated and needed to be cooled down; the original poster is really good at creating sensational headlines! Moreover, the details aren’t clearly stated either; the second condition seems to suggest that water can be used for cooling directly. It was only after reading the replies on pages 2 and 3 that I realized water cannot be used for direct cooling. There’s also a spelling error in the first condition – really, there’s nothing left to say! Did the poster post this to test the understanding and cultural level of the forum members? After finishing complaining, here’s my reply: What was suggested on floors 2 and 3 works; if we have the opportunity to replace the pump body with one that has a cooling water jacket, then the problem will be solved
I’ve always been curious about how concrete is pressurized and transported through pipes to heights of hundreds of meters for pouring; I’m even more curious about the pumps used to transport this powder. Could the poster explain how this pump works?
A more rustic approach is to wrap the pump body with copper pipes and use circulating water or chilled water for cooling; the downside is that there is a risk of the water valves being closed accidentally. It’s important to ensure proper insulation of the pump body after wrapping it with copper pipes, or else a jacketed heat exchanger can be installed on the pump. For long-term use, it might be better to opt for a pump equipped with a jacket
You really cover everything, no matter how small! You’re absolutely right; I’ve learned something from you
