Preparation: Dry towels, sharp tongs, bearings to remove the night, bearing lubricants or grease.
a. Dirty: Take the bearing out of the squeegee; wipe off the squeegee with a dry towel; then dry in a cool place.
b. Bearing shovel removal: soak the bearing in the bearing shovel removed on the market; and shake it at this moment; foreign objects inside the bearing will be shaken out; some supermarkets buy ultrasonic shovel is also very helpful in eradicating foreign objects.
c. Write the lubricant according to the trend to write grease or oil into the bearing; cover the cover and reattach the C-shaped ring.
d. Remove the C-ring and shroud: Use a dry towel to wipe off the dirt outside the bearing; then use a pointed plier to lift the side of the C-ring; take the C-ring and the shroud.
e. Detection: After the inner ring of the bearing that has been assembled into the original condition is caught by the finger, several transformations are made.
1, improve gear accuracy; the most direct.
2, increase the damping; choose a lubricant with a large viscosity.
3. Adjust the gap.
4, grinding gear; improved meshing accuracy

Product introduction
HHCMS-220 Carbon Molecular Sieve
The HHCMS-220 is a new nonpolar adsorbent designed to extract nitrogen-rich gas from air. It is suitable for separating nitrogen from air. It has a high adsorption capacity for oxygen and can separate nitrogen from air.
The most notable features of the carbon molecular sieve are high gas-producing efficiency and low energy consumption, especially for the preparation of nitrogen with a purity of less than 99.5% to 99.9%.

It is widely used in large air separation nitrogen equipment, and its application fields include coal mine, ship, oil storage and transportation.

Pay attention to
1. The nitrogen production equipment can reduce the adsorption temperature to better show its excellent nitrogen production performance under conditions;
2. Pay attention to low temperature drying and seal preservation during storage;
