Most die casting castings are iron-free

(4) grounding wire specifications: according to the provisions of the Ministry, the grounding wire must be made of more than 25mm2 bare copper flexible wire (5) is mainly used in non-horizontal direction of electrified movement and high and low voltage circuit breakers and machine tools as cable, hardware, power supporting components. When working, a certain amount of liquid refrigerant should be kept in the shell shell of the tube-like hair apparatus, and the liquid level should be controlled by a floating ball valve. The height of the hydrostatic level should be about about the diameter of the cylinder. Most of the cooling tubes are immersed in the liquid, and the heat exchange is carried out in a liquid-to-liquid way. Therefore, the heat transfer effect is better and the heat transfer coefficient is larger.
