JMZC  bearing Rust prevention work is an important piece of work, especially the process of rust, bearing in the heat treatment shop after pickling, cleaning, grinding, there are a number of processes. When the product is not used when the current production, a time order processing will be stored in the library in the Middle, so that process of rust the bearing rings must be stored.
A:ntn new technology of bearing Rust prevention:
1. the dipping after washing with concentrated sodium nitrite solution, containing 15%-20% of immersion in sodium carbonate aqueous solution of sodium nitrite and 0.6%, then stacked it up. This period of validity shorter, normally only 7-14 days can be maintained, but in the rainy season, due to wet weather, only 2-3 days left to be reprocessed, it takes labor and money.
2. apply oil coated with antirust oil like a finished product. This method must be implemented before the next process carries on the clean, too much trouble.
3. immersed in the JMZC  bearing in a rust-proof tank trap immersed in aqueous solutions of sodium carbonate 5% sodium nitrite and, antirust effect is good, but many rust-proof tanks and other equipment, take up a lot of space and management is not easy.
New rust-proof technology through joint research with relevant manufacturers and years of production experience has shown that the process improved rust multiple times to adopt water-injection corrosion better.
B: analysis of water hammer effect:
While the hammer produces a lot of noise, but the real damage was caused by mechanical failure. By kinetic energy changes dramatically static line pressure are known to hammer pipe support and damage or injury will overrun pipeline joints. Valves, water hammer can be generated by the valve core vibration, it may disable plug, gasket or packing.
