The development history of pumps in New China
Thread Content
After the birth of New China, it entered a great historical period of national economic recovery and construction. To meet the needs of agriculture and mineral resource development, the existing water pump manufacturing plant was promptly restored. The foundation of China’s pump industry was established during the 1950s to 1970s: by the end of 1953, significant progress was made in China’s pump industry, laying the groundwork for its development. The first specialized pump factories established after the founding of New China: State-owned: Shenyang Pump Factory ； Local state-owned enterprises: Changsha Machinery Factory, Chongqing Water Pump Factory, Benxi Machinery Factory; in addition, Guangzhou Heavy Machinery Factory also produces stainless steel acid-resistant pumps ； In the private sector: in Shanghai, there are Shanghai Machinery Factory, Huachang Machinery Factory, Sanfan Machinery Factory, Xinli Machinery Factory, Qiaxing Pump Repair Shop, Xinseng Machinery Factory, and Dalong Machinery Factory; in Beijing, there is Tongyi Water Pump Factory; in Wuhan, there is Kaiming Iron Factory Co., Ltd.; and in Changchun, there is Kuilijin Metal Pump Factory, among others. In 1949, China’s first specialized state-owned pump factory – Shenyang No. 6 Machinery Factory – was established. In 1950, the design department of Shenyang No. 6 Machinery Factory developed a set of standard parts that could be used across various types of pumps. These include fasteners, supports, lubricating components, seals, driving elements, etc., thus initially establishing a standardization system for pump components. By the end of 1951, the Wuhan Linzhong Research Institute had successfully replicated an 8-inch multi-stage pump with three stages. This pump has a flow rate of 110 m3/h, a head of 65 m, and a rotational speed of 2950 r/min; it is driven by a 40-horsepower diesel engine. In the same year, the Sixth Factory in the Northeast established its first technician training class. There are 50 students, and the program duration is one year. It opens up a path to improving the quality of skilled workers and serves as a precedent for factories running educational programs.
In 1954, the Shanghai Machinery Factory was put under public-private partnership. In June, Fan Jingchun designed China’s first 6-inch single-stage double-suction centrifugal pump on his own, drawing inspiration from the structure of Japanese CE-type single-stage double-suction pumps. The rotational speed increased from 1450 r/min to 2900 r/min, and the pump operates smoothly with low noise. From then on, our country entered a phase of independent self-design. Harbin Institute of Technology established a major in hydraulic machinery, taught by Soviet experts, and since then higher education institutions have had a specialized program for training experts in pump design. Shenyang Pump Factory invented the vortex pump and began using a \"motor balance\" to measure shaft power; this practice was adopted across the entire industry, with some factories still using it to this day. In 1955, the Shenyang Pump Factory successfully developed the 2II-19 type split-case pump, with an efficiency of up to 89%; it was the pump with the largest diameter among double-suction pumps at that time.

Changchun Lijin Pump Factory, Beijing Tongyi Water Pump Factory, and others were transformed into public-private partnerships. In 1956, the Shenyang Pump Factory conducted an in-house high-temperature test at 105 degrees Celsius on the 2.5IIB-1.5 vortex pump by using a closed-loop heating system; this method became a standard approach for high-temperature testing in the pump industry and is still being used to this day. The Changsha Pump Factory has successfully developed China’s first 24MII type split-case pump, with a diameter of 32 inches, a flow rate of 5000 m3/h, and a head of 26 meters. In early 1957, the Changsha Pump Factory produced the first 16II (20-inch) large vertical split-case pump, equipped with a 1015-meter long drive shaft, for use in deep wells for sewage treatment projects in cities such as Tianjin and Wuhan. Harbin Institute of Technology’s hydraulic machinery program has produced its first batch of graduates. From then on, our country had its own specialized professionals trained in the research and design of water pumps. Changsha Pump Factory produces 5 units of single-stage single-suction and single-stage double-suction centrifugal pumps, which are supplied to countries such as North Korea, Vietnam, and Albania as part of foreign aid programs. Under the leadership of Director Hu Guang of the General Machinery Research Institute of the Ministry of Machinery, Zhang Chuanbu, Zhao Zhisong, and Chen Aijiu developed the first set of standards for pumps, which included series specifications, acceptance test methods, and technical requirements for acceptance, thereby bringing the pump manufacturing industry into a more organized framework.
Interesting content, but not enough to satisfy me
It should be explained further regarding the liquid oxygen pumps and liquid hydrogen pumps used in China’s space programs, especially those used for liquid propellants in rocket engines.
The Northeast Sixth Factory is a topic that can be explored further
