Cleaning criteria for brushless DC water pumps

1. Ensure satisfaction with the cleanliness requirements of the parts. During repair, the cleanliness requirements vary for different parts. In the device, the cleaning requirements for cooperative parts are higher than those for non cooperative parts, dynamic cooperative parts are higher than static cooperative parts, and precision cooperative parts are higher than non precision cooperative parts. The cleaning requirements for the surfaces of workpieces that are sprayed, plated, and bonded are very high. When cleaning, it is necessary to use different cleaning agents and methods according to different requirements to ensure the required cleaning quality.

2. To prevent corrosion of parts, no degree of corrosion is allowed on precision parts. When parts need to be parked for a period of time after cleaning, the rust prevention ability of the cleaning solution or other rust prevention methods should be considered.

3. Ensure operational security, prevent fires or harm to human health, and prevent environmental pollution.

Cleaning project of DC brushless water pump

1、 Scrape off the scale and rust accumulated on the inner surface of the impeller, sealing ring, and bearings, and then clean and blow them clean with water or compressed air.

2、 Clean the accumulated oil and rust on the joint surfaces of the shell.

3、 Clean the water seal pipe and check if the inside of the pipe is unobstructed.

4、 Clean the bearing shell and bearings, remove oil stains, and then clean the oil ring and oil level gauge. Ball bearings are cleaned with gasoline.
