双吸泵具有结构简单、使用维修方便、性能优良等突出优点,在电厂、钢厂、水厂、市政、建筑等许多部门广泛应用。国内1957年设计的Sh型双吸泵、1967年设计的S型双吸泵,是双吸泵主导产品,几十年来未进行大的改进,基本保持原貌。与国外现代先进的双吸泵相比,在造型、结构、性能、工艺等方面都有一定差距。作为Sh和S型泵的更新换代产品,新开发的OS型系列双吸泵,具有以下特点:
Double suction pump has the advantages of simple structure, convenient use and maintenance, excellent performance and other prominent advantages. It is widely used in many departments such as power plant, steel mill, waterworks, municipal administration and construction. The Sh-type double-suction pump designed in China in 1957 and the S-type double-suction pump designed in 1967 are the leading products of double-suction pumps. They have not undergone major improvements in the past few decades and basically kept the original appearance. Compared with foreign advanced double suction pump, there is a certain gap in terms of shape, structure, performance, technology and so on. As Sh and S-pump replacement products, the newly developed OS-series double suction pump, has the following characteristics:
