Gland cover Fig. 1 The structure of a mechanical seal Usually, criticality evaluation for mechanical seals of centrifugal pumps depends mainly on artificial judgment, which is difficult to conduct due to the uncertainty and vagueness of the evaluation factors involved in criticality assessment, such as medium, material, operating temperature, operating pressure and so on.

Introduction Mineral resources are not only the important material base of economic and social development, but also the non-renewable precious resource, so it is the need of social sustainable development to implement mineral resource planning and management and improve the utilization rate of resources[1].But the traditional manual management mode of mineral resources is backward, efficiency is low and cannot be intuitive to understand the distribution of mineral resources, mining and mining safety factor and so on, can not meet the urgent need of the Department of land to mineral resources planning and decision-making.

Introduction The ceaseless progress of science and technology accelerate the development of city construction and expand the construction of city underground pipeline Today, the underground pipes are widely used in urban water supply and drainage systems, heating systems, gas supply system, and underground power embedded communication systems [1].However, due to the additional load of urban groundwater over-exploitation of underground resources, as well as the ground caused by a number of major projects [2], resulting in the foundation soil varying degrees of slow deformation [3] [4], the roads generate Subsidence [5].Degree of these factors in varying degrees, affect the normal use of the urban underground pipeline, resulting in the settlement of the urban underground pipeline sabotage [6], and ground subsidence [7] and collapse prone progressive, irreversible characteristics.These bring serious long-term effectsgive to the normal economic life of the city [8].China has been discovered
The experimental combination Taiyuan local underground pipeline data which exsiting n the road along the buried and space,Which include line interface size, spatial arrangements, material composition information, to create 1:1 experimental model to simulate the deformation and failure pattern of the underground pipeline in the foundation soil differential settlement in indoor geotextile slot,To analyze the cause of the formation mechanism of the road along the ground subsidence and collapse, and to establish the underground pipeline early warning mechanism which to prevent the damage of the pipeline because of the underground soil subsidence and collapse,and to ensure the normal use of the underground pipeline.
