1. What kind of cleaning effect should be achieved (decontamination/degreasing/wax removal/rust removal/fingerprint removal/oxidation prevention)
2. What is the maximum size of the workpiece to be cleaned
3. How many products need to be cleaned during the working hours of a day, and how much is the maximum capacity of the machine to be purchased
4. What kind of cleaning process is required (need drying)
5. Select a professional manufacturer (Jiangmen Hengtai Cleaning Equipment Co., Ltd.) to compare the cleaning process, price and after-sales service guarantee
6. When signing the contract, the brand and model of the materials used for the equipment, the price of consumables, maintenance terms, etc. shall be written into the contract
7. Acceptance, if it is a large equipment, try to take the workpiece to the manufacturer for on-site acceptance
8. Training for the company's operating staff after installation to prevent some small problems during the use of equipment from affecting the production progress.

The ultrasonic cleaning frequency of power selection ranges from 28 KHZ to 120 KHZ. The physical cleaning force caused by cavitation when using water or water cleaning agent is obviously beneficial to low frequency, generally about 28-40KHZ. For parts with small clearance, slit and deep hole, it is better to use high frequency (generally above 40KHZ) for cleaning. Cleaning agent temperature The most appropriate cleaning temperature for water cleaning agent is 40-60 ℃. Especially in cold weather, if the cleaning agent temperature is low, the cavitation effect is poor, and the cleaning effect is also poor. Therefore, some cleaning machines wind heating electric wires around the outside of the cleaning cylinder for temperature control. Cavitation is easy to occur when the temperature rises, so the cleaning effect is good. When the temperature continues to rise, the gas pressure in the bubble increases, causing the impact sound pressure to drop, and the effect will also be weakened. Organic solvent cleaner should be cleaned at a temperature close to the boiling point.
