A university of science and technology mainly engaged in the study of fiber laser had purchased S&A CW-5000 water chiller to cool their fiber laser. As cutting machine was additionally used in their later research, they placed another order with us for CW-5000 water chiller to coo
The magnitude of the force of the single-pillar is determined first by the pressure of the top plate, and sometimes by the mechanical properties of the bottom plate and whether the top beam is compressible. The distribution of the load on the single struts on the beam depends on how the top beam is
During the mining process, coal or rock mass with a large amount of elastic energy accumulates under high stress conditions, and suddenly breaks, falls or throws under certain conditions, causing sudden release of energy, showing obvious sound, vibration and air waves. The dynamic effect. These phe
