The application of PLC in the equipment transformation for transistor seal;

This paper expounds the equipment transformation of comprehensive mechanized coal mining face in Chengzhuang Coal Mine, including the transformation of the tail of the extensible conveyer, the updating and transformation of gate equipment and the updating of gate belt conveyer.

Taking the main ventilating engine as the example, this paper discusses on the necessity of the technical measurement of the large - scale equipment and the basic measuring methods, and probes into the results of the technical measurement of the technical equipment in aspects of the equipment transformation and the energy conservation.

It gives summary on the equipment reformation, commissioning and start-up, problems and solutions.

The main technical requirements, scheme, technical and economical indices of typical design for power transmission and transformation project were introduced, and the existent problems in equipment manufacturing and material processing at present were pointed out.

The relationship between the delivery condition of the pressure vessel materials and the materials′ actual properties,together with the hot forming and heat treatment in the process of equipment manufacturing was discussed.

As a result, the running benefits of the foundry equipments has been largely increased.
