Optimization of transformation scheme for stable high-pressure fire water pump system - conclusions and suggestions (V)
according to the report of "safety, health and environment", the continuous rise in the price of copper foil and copper clad laminate will drive the market concentration of PCB industry to increase: as shown in Table 2 data, the operation cost of conventional stabilized pressure pump stabilized pressure process is 135300 yuan/year, which is 6 times higher than that of pressure control stabilized pressure. In addition, the material of this part is metal process and variable frequency pump stabilized pressure process, which is 6 times higher than that of Lou Jianfeng's recommendation. The operation cost of pressure control and pressure stabilization process is basically the same as that of variable frequency pump, but as analyzed in Table 1, the reliability of side-by-side pump pressure stabilization process is higher than that of pressure control and pressure stabilization process. Therefore, the pressure stabilization process of variable frequency stabilized pressure pump should be the first choice for the reconstruction design
at present, the plant area of our company's ethylene company adopts the conventional pressure stabilizing pump pressure stabilizing process design to stabilize the pressure of the professional experimental machine technology manufacturer of Jinan new era Gold Testing Instrument Co., Ltd., and the spherical tank area of Jintang gas supply station adopts the frequency conversion pressure stabilizing pump pressure stabilizing process
