The cold rolled steel sheet is cold-drawn once in the rolling track to ensure the precision of the rail cross-section dimensions, which replaces the unsafe of the angle steel and other conductive methods. The weight is heavy, the indoor slide wire is ash, and the outdoor ice causes the circuit to be short and slightly affected. Disadvantages, but also has the characteristics of domestic originality, the track unit length 4 ~ 6m using coupler connector, can be extended to any length as needed.
The working principle of this product is shown in the engineering application diagram (1) The beginning of the flat cable (connected with the field junction box) is fixed on the starter of the lead rolling mill, and the appropriate length (1-2.5mm) is allowed according to the allowable space for on-site operation. ) It is fixed on the four-wheel trolley carrying the cable in turn, and the cable end (power supply for use) is set on the last trolley (trailer). Through the reciprocating movement of the spring-pulled trolley on the cart, the dragging of the cable (length exceeding 20m, for example, the original traction rope should be taken into consideration to prevent the cable from pulling force), all the carts can be freely slid at any speed in the rolling path, and the rail is installed. Simple, no debugging, and no contact with the power supply, safe and reliable.
Green agricultural products refer to non-polluting safe, high-quality, and nutritious agricultural products that follow the principles of sustainable development, are produced in accordance with specific production methods, and are approved by special agencies to use green food labels. Such as green wheat, green rice, green vegetables, green fruits, green livestock and poultry meat, green aquatic products, etc.
China's green agricultural products are divided into A-level and AA-level, and A-level is the primary standard, which allows the use of safer chemical fertilizers and pesticides during the growth process for a limited time, a limited number, and a limited variety. AA grade is high-grade green agricultural products.
Percy Misika, the representative of the United Nations Food and Agriculture Organization in China, emphasized in his speech that organic agriculture plays an important role in promoting food safety. In the entire food value chain, it uses fewer resources and improves agricultural efficiency.
