How to choose the specifications and models of XBD fire pumps? How to choose a fire pump correctly

The use of fire pumps nowadays has made it convenient for people to use various fire-fighting equipment in their daily lives, and there are many models of fire pumps. When choosing, we need to select the correct model. So, how to choose the specifications and models of XBD fire pumps? Follow Sanli Water Supply to learn more.

　　Selection knowledge

The selection of fire pumps should be based on the process flow of the fire pump application project, water supply and drainage requirements, and consider five aspects: liquid delivery volume, device head, liquid properties, pipeline layout, and operating conditions.

The types of pumps used for fire protection systems are similar, only with different head and flow rates. The flow rate of the transported liquid is one of the important performance data for selecting a fire pump, and the flow rate of the transported liquid directly affects the production capacity of the entire device.

XBD fire pump specifications and models

　　There are several points to pay attention to when purchasing a fire pump

1) The performance of the fire water pump should meet the requirements of the flow rate and pressure required by the fire water supply system;

2) The power of the driver equipped with the fire pump should meet the requirements of the power required for operation at any point on the flow head performance curve of the selected pump;

When using an electric motor-driven fire water pump, a dry-type fire water pump with an electric motor should be selected;

4) The flow head performance curve should be a smooth curve without humps or inflection points. The pressure at zero flow should not exceed 140% of the design working pressure, and should be greater than 120% of the design working pressure;

When the outlet flow rate is 150% of the design flow rate, the outlet pressure should not be lower than 65% of the design working pressure;

6) The sealing method and material of the pump shaft should meet the requirements for the operation of the fire pump at low flow rates; The small rated flow rate of a single fire pump should not be less than 10L/s, and the large rated flow rate should not exceed

7) The model of fire water pumps in the same pump group for fire water supply should be consistent, and the number of working pumps should not exceed 3;

When multiple fire pumps are connected in parallel, the impact of flow superposition on the outlet pressure of the fire pumps should be checked.

Fire pumps are very important in the economic interests of factories, and they are an indispensable role in the fire protection industry. Therefore, the quality of fire pumps must be up to standard. Only in this way can the BD/BHYL electric fire pump set be used in production with peace of mind. The specifications and parameters of XBD fire pumps are also important for fire pump manufacturers to pay attention to. Be a conscientious manufacturer and produce conscientious products.
