Analysis and application of advantages of ultrasonic cleaning agent for bearing parts

How to use ultrasonic cleaning agent (LQ-5 ultrasonic cleaning agent):

Generally, according to 5-10% of the original solution, the solution is filled with water, and the amount of the original solution is 1 to 3%. The temperature is 25 to 60 ° C. The recommended temperature is 40 to 60 ° C. The ultrasonic cleaning time is 1 to 30 minutes. Dry it. The specific cleaning process should be based on the actual production situation, and the professional technical engineer can formulate the cleaning plan before use.

Advantages of ultrasonic cleaners:

1. The cleaning effect is good, the cleanliness is high and the cleanliness of all the workpieces is consistent.

2. The cleaning speed is fast, the production efficiency is improved, and the cleaning liquid is not required to be touched by human hands, which is safe and reliable.

3. The deep holes, slits and hidden parts of the workpiece can also be cleaned.

4. No damage to the surface of the workpiece, saving solvent, heat, work site and labor.

The cleanliness of a rolling bearing has a large effect on its vibration, hum, noise and service life. Especially in the production of small low-pitched deep groove ball bearings, improving the cleanliness is one of the keys to solving the humming and abnormal sound of the bearings, so the cleaning process is a very important part. Bearing cleaning is generally divided into two steps in the production process, that is, the parts before the assembly (ferrules, steel balls, retainers, etc.) are cleaned and assembled after riveting.

The three factors that determine the cleaning effect are: cleaning medium (cleaning solution), cleaning process and cleaning device.

According to the design and foundation of the cleaning system, based on the design basis and actual needs of the cleaning system, the typical cleaning process of the finished bearing products with ultrasonic cleaning and spray cleaning as the cleaning method is determined: demagnetization → initial spray → ultrasonic cleaning → fine spray →Air knife blows clean → secondary blows → hot air drying.

According to the cleaning process, the mechanical structure design of the cleaning device adopts the control system of the robot arm by the PLC, which realizes the manual and fully automatic control of the device, and does not need to adjust the positioning device with the change of the bearing size to achieve accurate positioning. In the three main cleaning stations of ultrasonic cleaning, fine spraying and secondary blowing, a rotating mechanism is designed to ensure the sufficiency of cleaning.
