Variable frequency vibration motor is a kind of hydraulic material. Building materials such as limestone will loosen when exposed to water, while variable frequency vibration motor will gradually harden after being exposed to water. Variable frequency vibrating motors are mixed with sand and gravel and water to form concrete. Concrete has good compressive performance, but its anti-interference ability is very poor. Because the cement can bond well with the steel bar, and the steel bar wrapped with frequency conversion vibration motor can avoid rusting, so steel can be used to make up for the shortage of concrete tensile strength. Today, I will show you how to prevent variable frequency vibration motor bearing rust!

 Vibration motor

1. Solvent free paint shall be used as far as possible.
2. If possible, use impregnating varnish without oxidation components, such as epoxy urethane or unmodified epoxy based impregnating varnish.
  3. When using cyanuric acid impregnating varnish, the curing temperature and curing time should be adjusted. The curing temperature should be slightly higher than 130 ℃ (e.g. 135 ℃) and the curing time should be longer than 180 min. moreover, the process must be strictly implemented. Especially in the high temperature and humidity season, the rotary vibration screen is not necessarily sufficient for the paint drying (curing) time specified in the paint factory samples from the perspective of rust prevention The internal shape of the body.
4. Paint without volatile acid is used.
5. Choose the paint with good hydrolysis resistance.
6. Mineral oil bearing grease shall be selected as far as possible.

  7. When the motor factory injects lubricating grease by itself, in order to avoid water vapor and dust in the air from entering into the bearing to produce noise and another possible corrosion factor, the grease container should be sealed, even during grease injection, and the amount of grease injection should be certain according to the standard. If 6202 bearing is used, the reference value is in the range of 0.60-0.80g, and the grease injection process should be maintained Clean and dry.

8. Plastic film packaging with micro hole movable rotary screen is selected. The rotary vibration screen can make the motor have certain air permeability before it is used. When sealed with plastic film, the paint gas will stay in the bearing, and the moisture will condense, which should be avoided.
