Pumps are widely used in power, chemical, metallurgy, petroleum, agriculture and other sectors of the national economy, is the energy onsumption of large, annual power consumption of the pump accounts for about 1/5 of the total power generation. Therefore, it is very important to improve the safety and economy of the pumps in various production systems. Rapid diagnosis of pump failure, reasonable maintenance of equipment, and constantly improve the operation of the pump in the system effect is engaged in pump equipment design, installation and maintenance of engineering and technical personnel common goal.
In recent years, there are some weak links in the field of pump maintenance, the quality of work and work efficiency are inadequate, the main reason is that a large number of mechanical engineering graduates in the years after graduation, the work is done and maintenance, And engineering students in the school almost no maintenance of equipment in the field of formal training; industrial production in the actual repair business, more by the experienced but no academic engineers or workers to deal with these people also lack the basic training of various basic training , So can not carry out a high level of maintenance work; pump maintenance project managers have received high engineering education, generally only from the instructions to engage in repair, and equipment designers generally lack the use of experience, but also from the user feedback is less, So the development of the pump maintenance instructions are not necessarily reasonable.
