Self-priming pump selection data
1. The importance of basic data for self-priming pump selection
The most critical link before purchasing a self-priming pump is to understand the basic data of self-priming pump selection. Only after understanding the basic data of relevant self-priming pumps can you choose a self-priming pump product that meets the requirements of the working conditions.
2. Basic data of self-priming pump selection:
1. The basic data of self-priming pump selection must first understand the specific medium of the liquid being transported. The name of the main liquid, the main characteristics of the liquid (such as whether the liquid is corrosive, restorable, flammable, explosive, toxic, etc.), how high the specific temperature of the liquid is, whether it contains particles, what is the content of particles, and the diameter of the particles What specific particles, the density of the medium, the viscosity of the medium, etc.
2. Then determine the performance parameters of the self-priming pump. First of all, you need to understand the flow rate required by the user, and then you need to know the length and height of the self-priming pump inlet pipe in which area it is convenient to use and check the atmospheric pressure to calculate whether the suction length of the self-priming pump can meet the working conditions and the outlet system piping of the self-priming pump Arrangement; how high is the specific vertical height, how many meters of horizontal distance, how big the pipe diameter is, the number of elbows, the number of valves, what is the purpose of pumping the water out of the self-priming pump, whether there is pressure at the end, etc. so that the manufacturer can choose the right lift for you Of self-priming pump products, understand the operation mode of the device (intermittent operation or continuous operation).
3. Other working conditions that should be understood when selecting the self-priming pump. When selecting the self-priming pump, it is also necessary to consider the limitations of the operating environment, the budget cost, the installation location of the self-priming pump, safety (such as transporting flammable and explosive liquids or the environment requires an explosion-proof motor), and whether the environmental pollution is Self-priming pumps are required to meet the requirements of non-leakage functions, such as vertical non-leakage self-priming pumps.
