The daily maintenance of ultrasonic cleaners
I am a ordinary maintenance technician, production workshop is mainly responsible for enough power of ultrasonic cleaning machine and maintenance work, the problems loom in my hands, most of the problem was caused by improper maintenance, therefore, I think it is necessary to provide the ultrasonic cleaning machine daily maintenance knowledge to customers, for customers to reduce the problem of the trouble.
Ultrasonic cleaning machine is common problem is the rust cleaning trough. Some customers feel strange, say good stainless steel? How can rust. Is also based on this understanding, many customers in the use of ultrasonic cleaning machine, do not pay attention to maintenance, whether in any liquid, even a caustic soda acid liquid, use after all is thrown in there, don't wipe clean, even there were a lot of fluid in the cleaning tank, over time, thus lead to the problem of rust cleaning trough. So, why stainless steel rust?
Most people are very strange, think "stainless steel is not rusty, rust is not stainless steel, is likely to be the problem of steel". Actually, this is a one-sided error for a lack of understanding of stainless steel. Stainless steel under certain conditions will be rusty.
Ultrasonic cleaning machine for long-term exposure to liquid tank is one of the most affected by corrosion test, the stainless steel lining has the ability of resistance to atmospheric oxidation - namely, stainless, also has in the medium containing acid, alkali, salt is the ability of corrosion - namely, the corrosion resistance. But the size of its ability to resist corrosion was with the chemical composition of steel itself, and each state, using conditions and environmental medium type and change. As 304 steel tube, in dry, clean atmosphere, have absolute good corrosion resistance, but it will be moved to the coastal areas, in contains a great deal of sea salt fog, will be easy to rust; And 316 steel tube is good. So, not any kind of stainless steel, in any environment corrosion, no rust.
So, in order to ensure the surface of the permanent bright metal, not rust, we suggest:
1, decorative stainless steel surfaces must often swabbed clean, remove attachments, eliminate the cause of external factors.
2, coastal areas or use strong acid and alkali cleaning liquid to use material 316 stainless steel, 316 material corrosion resistance to sea water.
3 some ultrasonic cleaning machine on the market, the use of stainless steel pipe can't conform to the corresponding national standards, chemical composition of less than 304 material requirements, which will cause rust, which requires users to carefully choose reputable manufacturers of products, so customers in the ultrasonic cleaning machine not only focus on the price of choose and buy, some cheap it has its problems exist.
Ultrasonic cleaners another common problem is the fuse burned, although this problem is easier to rule out, it is ok to just change the fuse, but also should pay attention to the using way, to avoid unnecessary trouble. Fuse is burning is usually caused by voltage instability, excluding grid is not stable, then we did not pay special attention to during the using, arbitrary power, machine, under the frequent switch will cause current impact, resulting in the fuse is burnt.
Then there is, for small ultrasonic cleaning machine, is work time, because of its lack of cooling system, so in the process of long-term continuous use, ultrasonic vibration smaller time under the high frequency vibration produces heat, heat cannot effectively ruled out can cause overheating, eventually burn components. The correct method of use is the use of 40 ~ 60 minutes should be ultrasonic cleaning machine rest for 10 minutes or so. If the production need long time operation, it is recommended that the custom industrial single slot ultrasonic machine.
Ok, I'll stop here, hope can help our customers.
