Do you know the precautions for the selection and application of fire pumps? How much do you know about fire pumps? A full understanding of a product can make better use of its advantages. Let's take a look at it with Xiaobian now.
Selection and application of fire pump: 1) The performance of the fire pump should meet the requirements of the flow and pressure required by the fire water supply system; 2) The power of the drive equipped with the fire pump should meet the requirements of any point on the selected pump flow head performance curve. Power requirements; 3) When using a motor-driven fire pump, the dry-mounted fire pump should be selected; 4) The flow head performance curve should be a smooth curve with no hump and no inflection point, and the pressure at zero flow should not be More than 120% of the design working pressure; 5) When the outlet flow is 150% of the design flow, the outlet pressure should not be lower than 65% of the design working pressure; 6) The sealing mode and material of the pump shaft should meet the low temperature of the fire pump The requirements for operation at flow rate; 7) The type of fire pump for the same pump group of fire water supply should be the same, and the working pump should not exceed 3 units; 8) When multiple fire pumps are connected in parallel, the influence of stacking flow on the outlet pressure of the fire pump should be checked.
The above is the knowledge analysis of the fire pump that we bring to you. If you need to buy a fire pump, please contact us, we will provide you with quality products, we look forward to working with you, we will be happy to help you.
