Inventory! Moisture-proof and dust-proof measures for mechanical fasteners

For vibrating machinery, the environment in which it is used is more responsible, and it is usually humid and dusty, which will cause great damage to mechanical fasteners. Fasteners are important parts of machinery. How How to protect mechanical fasteners?

1. Moisture-proof measures

(1) Use solvent-free paint as far as possible for vibration machinery.

(2) It is best to use impregnating varnishes that do not contain oxidizing components, such as Epoxy-urethane-based or undenatured epoxy-based impregnating varnishes.

(3) When using melamine dipping varnish, the curing temperature and curing time should be adjusted. The curing temperature should be slightly higher than 130℃ (such as 135℃) and the curing time should be longer than 180min, and it must be strictly implemented Process, especially in the hot and humid season, because from the perspective of anti-rust concept, the paint drying (curing) time specified in the sample of the paint factory is not necessarily sufficient, and the motor has a specific internal shape.

(4) Use paint without volatile acid.

(5). Choose paint with good hydrolysis resistance.

(6) Try to use mineral oil-based bearing grease.

Second, how to prevent dust (Guide: Fasteners and screws are prone to undesirable phenomena)

The vibration self-locking nut motor does not have an electric fan to dissipate heat, and it depends on natural cooling. In addition, the working conditions are mostly very vulgar, dust is large, and dust is easy to deposit in the motor heart, which causes the internal temperature to be too high, leading to failure. How to effectively prevent dust?

(1) Regularly remove the internal dust of the vibration motor to make it work in a good condition;

(2) In the design process, the vibration motor core should be as lubricated as possible so that dust is not easy to accumulate. If you are working with a lot of dust, you should consider subtracting the heat dissipation ribs inside the core, because at this time, The radiating ribs not only fail to dissipate heat, but are easy to deposit dust and hinder the heat dissipation of the vibration motor.
