Help: Recommend a small portable high-pressure washer for cleaning scale from heat exchangers
Thread Content
The mobile high-pressure washers in use now (with a pressure of 30–50 Mpa) have very poor stability; they stop working after just 3 or 5 uses... I’m looking for a domestically produced model that is reliable
Try entering the term “car washing pump” on Taobao :)
It’s not a car washing shop – if what’s bought doesn’t work, there will be consequences :@:@
Oh, so it’s a child who doesn’t understand proper behavior. I gave you my well-intentioned advice and guidance, yet you respond to me with this:@:@ If I were your supervisor, I would deal with your ignorance and lack of awareness by keeping you away from this field.
KaiChi’s products aren’t too expensive either these days

I’m sorry for offending you; I thought you were joking, so I just used an angry emoji without realizing there was also the “knife” symbol. I’m apologetic! What I want to say is that before giving sincere advice to fellow travelers, it’s better to look up relevant information unless you really understand the matter well. I can check my own posts and replies; I’ve never dared to give anyone ‘advice’ There is only learning, discussion, and suggestions. I already said that the pressure is around 30-50 Mpa. Do consumer-grade car wash machines have such high pressure? ? Which car wash pump can generate such high pressure? I doubt they would dare to sell it publicly! I once again apologize to you, my senior, for my ignorance and unreasonable behavior! I may not be sensible, but someone who is almost 50 is no longer a child. Whether I’m involved in the chemical industry or not, my boss probably wouldn’t dare to make absolute statements about me. Hehe
To be honest, we have mobile cleaning machines like yours here. The idea is good, but in actual use the heat exchanger provides a very poor level of clarity; for now, all that can be done is clean the floor of the device. Currently, the heat exchanger is being cleaned, using 1 machine and 2 high-pressure washers.
I’ve been using small cleaning machines here to clean the tubes of graphite heat exchangers as well as the graphite blocks; as long as there is no blockage, the cleaning works fine. These are Swedish-made cleaning machines – those costing 50,000 to 60,000 yuan stop working after just a few uses. Outsourcing high-pressure cleaning involves using cleaning vehicles and equipment worth millions of dollars, with charges based on the area to be cleaned (any additional costs are to be borne by the workshop; outsourcing this service is generally avoided unless it is absolutely necessary). A friend upstairs recommended the Kächi machine, which is German-made and seems pretty good. I just got in touch with them; it’s cheaper than what we’re using currently, so I plan to buy one and give it a try. I also have a cleaner for washing blower impellers here, but its pressure isn’t high enough; it can only clean the impellers and the floor, etc. Thank you all
Is the pressure reduction too rapid? It is recommended to increase the pressure gradually.
