Mechanical diaphragm pump body how to choose

In this front, Xiaobian introduced the working principle of the mechanical diaphragm pump, today, we talk about the mechanical diaphragm pump valve body. Mechanical diaphragm pump body type selection is the most important part of the diaphragm pump selection, the specific factors to be considered should pay special attention. Let Xiaobian let you tell you how to choose mechanical diaphragm pump body. Mechanical diaphragm pump body how to choose Mechanical diaphragm pump there are many body types, commonly used through a single seat, through two-seater, angle, diaphragm, small flow, tee, eccentric rotation, butterfly, sleeve, spherical, etc. Species. Before selecting a valve, carefully analyze the medium, process conditions, and parameters of the control process, collect enough data to understand the system's requirements for a mechanical diaphragm pump, and determine the type of valve to be used based on the data collected. In the specific choice, the following aspects can be considered: 1, the spool shape and structure based on the selected flow characteristics and imbalance forces and other factors to consider. 2, wear resistance: When the fluid medium is a suspension containing high concentrations of abrasive particles, the valve core, the seat surface each time the closure will be severely rubbed. Therefore, the flow of the valve should be smooth, the valve's internal material to be hard. 3, corrosion resistance: As the medium is corrosive, in the case to meet the regulatory function, try to choose a simple structure of the valve. 4, medium temperature, pressure: When the medium temperature, high pressure and changes in the large, the valve core and seat material should be selected by the temperature, pressure changes in small valves. 5, to prevent flash and cavitation: Flash and cavitation only produce liquid medium. In the actual production process, flash and cavitation not only affect the calculation of flow coefficient, but also the formation of vibration and noise, so that the valve life is shorter, so the valve should be selected to prevent flash and cavitation. The five factors described above is Xiaobian today to tell you how to choose the mechanical diaphragm pump body, from the introduction, we understand the importance of valve body selection, and factors that should be considered. In fact, no matter the valve body or other components, there should be a carefully chosen process. So everyone's choice of mechanical diaphragm pump to better work.
