Vertical condensate pump seal reform has been widely used

Since Zhanjiang implemented the first condensation pump sealing reform in 2001, the pump has been operating normally for nearly four years and has reached the standard of a maintenance cycle required by the power plant. During this period, the maintenance volume of the sealed part of the pump is zero and the The power plant-related technical staff generally recognized, at present, the plant several other units condensate pump has been completed transformation. After the power system internal communication and technology exchange, this technology has been widely used in other power plants. Some representative ones are Guangdong Zhanjiang Power Plant, Hunan Jinzhushan Power Plant, Hubei Yangluo Power Plant and Jiangxi Fengcheng Power Plant. According to the customer's general response, the retrofit has the following outstanding advantages: 1. The retrofit implementation time is short - only when the condensate pump is repaired in the power plant, it is easy to reconstruct, almost not taking over the effective time of the overhaul. 2 High seal integration - An integrated component (cartridge mechanical seal), a substantial reduction of spare parts inventory, spare parts error rate is zero 3 does not modify the original structure of the device - the transformation only to cancel the original packing and gland, without any modifications to the pump body, Significantly reduce the risk of retrofit, which is more important in the initial implementation of the retrofit unit 4 Reduce spare parts consumption - The seal service life of four years, eliminating the need for packing of packing, bushings and other spare parts, reducing inventory funds 5 Reduce operating costs - Because the frictional power consumption of the mechanical seal is much lower than the packing friction, increase the running stability, reduce the operating load and save operating costs 6 Labor-saving - the daily maintenance of almost zero, and then Do not have to frequently replace the packing and sleeve
