Description

Technical Field

[0001] The utility model relates to the technical field of pump valve production and processing, in particular to wear-resistant stainless steel pump valve castings. Background Technique

[0002] Pump valves are the general term for pumps and valves, not valves used for pumps or valves with pump functions. Applied to liquid transportation, the reason why pumps and valves are often associated is the usage scenario. That is to say, where there is a pump, there is generally a valve, and where there is a valve, a pump is often needed. They are both used in places for liquid transportation. Of course, valves are also used for gases. Vacuum pumps are also related to gases. The Pump Industry Branch of China General Machinery Industry Association held a China water pump industry operation work conference in Zibo, Shandong. At the meeting, Professor Zhang Shengchang, the director of the Industrial Pump Research Institute of Zhejiang University of Technology, suggested that for the currently market-urgent integrated innovative centrifugal pumps, large-flow and high-efficiency reciprocating oilfield injection water pumps and other high-efficiency energy-saving and environmentally friendly characteristic pump products, Chinese pump manufacturing enterprises should actively develop them, which can not only meet the needs of users but also create new profit growth points for enterprises.
