Relative humidity, temperature: 95%+40Â°C
2. Atmospheric conditions: Relative humidity <90% at +40Â°C
3, pollution level: IP13, IP23 is 3; IP54 is 4
4, vibration and shock: no violent vibration or foreign body impact, drop
(1) Look-up table method: According to the site load configuration total power, load continuation rate, use environment, crane model, tonnage, category determine the conduit specification.
(b) Power estimation method:
1. Calculate the total power of the load n loads start simultaneously: âˆ‘ P = P 1 +P 2 +......+P n
Only one of n loads starts: âˆ‘ P=P n
2, check the table to find out P n
3, P n > âˆ‘ P
4. The load continuation rate and the allowable ambient temperature should be equivalent.
It is a typical silicate material made of natural raw materials such as feldspar, clay and quartz. The main constituent elements are silicon, aluminum and oxygen. These three elements account for 90% of the total amount of crust elements. Low cost and mature technology. Such ceramics can be divided into daily-use ceramics, architectural ceramics, electrical insulating ceramics, chemical ceramics, etc. according to their performance characteristics and uses. It is made of high-purity synthetic raw materials and is formed by precision control process. It generally has some special properties to meet various needs. According to its main components, there are oxide ceramics, nitride ceramics, carbide ceramics, cermets, etc.; special ceramics have special mechanical, optical, acoustic, electrical, magnetic, thermal and other properties. According to different uses, special ceramic materials can be divided into structural ceramics, tool ceramics, and functional ceramics.
