Bearing and shaft fit tolerance standard

Bearing and shaft fit tolerance standard ①When the bearing inner diameter tolerance zone and the shaft tolerance zone form a fit, the tolerance code originally belonging to the transition fit in the general basic hole system will become an over-win fit, such as k5, k6, m5, m6, n6, etc., but the over-win amount is not Large; when the bearing inner diameter tolerance is matched with h5, h6, g5, g6, etc., it is not a clearance but an over-win fit.

The basic theoretical knowledge of air that everyone who uses an air compressor should understand

1 What is air? What is normal air? 　　 Answer: The atmosphere around the earth, we are accustomed to call it air. 　　The air under the specified pressure of 0.1MPa, temperature of 20°C and relative humidity of 36% is normal air. Normal air is different from standard air in temperature and contains moisture. When there is moisture in the air, once the moisture is separated, the air volume will be reduced.

Piston compressor use and maintenance technology

Preparation before start-up: Operation, repair and maintenance must be carried out by self-made people. The compressor should be unsealed and cleaned before use, and check whether there is rust on each friction surface. The rust phenomenon should be cleaned with oilstone grinding and clean, and the friction surface should be coated with lubricating oil after unsealing.

The cold storage is constructed in this way, and it saves nearly half of the electricity bill!

The cold storage is constructed in this way, and it saves nearly half of the electricity bill!<br></br> Compared with ordinary refrigerators, cold storage has a larger cooling area, and because of the large cooling area, the power consumption is relatively large. Today I will show you how to make cold storage more energy-efficient.
