&At present, it has entered the key point of urban winter heating, which is concerned by citizens and leaders of the city. The heating relay pump station contracted by the second group company naturally becomes a key project. &On November 8, 2016, Liu Shuguang, mayor of Weifang Municipal People's government, and Liu Jianguo, vice mayor, inspected the relay pump station project built by the second company of the group, accompanied by the heads of relevant departments of the municipal government. Xu pengqiang, chairman of the group and Yan Peng, deputy general manager, accompanied the inspection on site. Liu Shuguang fully affirmed the quality and progress of the project, and made further requirements for the next work. It is expected that after the high-voltage power is connected on November 11, the pumping station equipment will immediately operate, and then it will be able to meet the heating demand of 50000 users in the city, and will successively meet the heating demand of 200000 in the city later stage. &It is reported that the relay pump station project from Weifang Power Plant to Kuiwen District high temperature water heating main pipeline (phase II) is located in the northwest corner of the intersection of Baotong street and Xinhua Road, Kuiwen District, Weifang City, Shandong Province. The project is approved by Weifang Municipal People's government and the owner of the project is Weifang Minsheng Thermal Power Holding Co., Ltd. &In order to overcome the resistance of the network, the relay pump station uses return water to pressurize. This design is the return pump supercharging thermal system. Reinforced concrete structure is adopted for pump house, pump station electrical equipment room and office room. According to the hydraulic calculation, the total circulating water volume in the station is 12900t / h, and the return water pipeline is pressurized by 1010kpa. &During the construction period, the second company of the group, adhering to the group's concept of "social value is higher than economic benefit", carefully organized the construction, and in the coming winter, which may be colder, provided Weifang citizens with another fine livelihood building.
