The boiler capacity of thermal power plant is larger than that of thermal power plant of the same scale due to both power generation and heat supply. Therefore, it is necessary to add more boiler capacity for standby than thermal power plant, and the water treatment capacity is also large. Therefore, the boiler feed pump used has the characteristics of large flow and high head. With the increasing of boiler capacity and pressure, the former boiler feed water pump has higher and higher requirements for the characteristics of the water pump. The original boiler feed water pump has failed to meet the requirements of normal use, with high maintenance cost and large power consumption.
According to the original structure (base, pipeline, spatial layout) of the pump house of the thermal power plant, our company has designed the self balanced boiler feed water pump which is most in line with the actual situation through comprehensive consideration according to the original structure (base, pipeline, spatial layout) of the pump house, so as to minimize the transformation cost of the pump house. In order to ensure that the mechanical seal of the self balancing boiler feed pump can still have high stability under high pressure environment We hereby agree with the mechanical seal production company to customize the balanced mechanical seal according to the pressure situation. On the basis of the original design of the company's water pump, the cooling system of the mechanical seal is added to ensure that the mechanical seal is stable in the normal temperature environment of 70 ° to 80 ° and maintain the high stability of the mechanical seal in the operation process.
