Fire pumps are widely used firefighting equipment nowadays. The use of fire pumps ensures that we can prevent fires and extinguish them in a timely manner. Therefore, in order to protect personnel safety, they are installed in many occasions. Follow Sanli Water Supply to learn about the specifications and parameters of XBD fire pumps.

　　XBD fire pump

As the name suggests, fire pumps are pumps used in firefighting and are classified into different types based on their characteristics of being fully sealed, leak free, and corrosion-resistant. They are widely used in environmental protection, water treatment, firefighting, and other departments to pump various liquids. They are ideal for creating leak free, pollution-free civilized workshops and factories. The types of pumps used in firefighting systems are similar, but the head and flow rate are different. The selection criteria for fire pumps should be considered from five aspects based on the process flow and water supply and drainage requirements. The XBD fire pump refers to a fire pump driven by an electric motor.

XBD fire pump specifications and parameters

　　Cover and maintenance of XBD fire pump during operation

1. The inlet pipeline must be filled with liquid to prevent the pump from running for a long time under cavitation conditions.

2. Reflect on the current value of the electromechanical system on time and do not exceed the additional current of the electromechanical system.

3. After the pump stops running for a long time, if the machine wears out and the sound and vibration of the unit increase, it should be parked for reflection. If necessary, vulnerable parts can be replaced. The overhaul period of the unit is also usually one year.

　　The meaning of fire pump XQB3.3/30-125-160

XQB represents the fire pressure stabilizing water supply equipment

3.3-0.33MPa

30-30L/S

125- Pump inlet and outlet diameter (mm)

160- nominal diameter of impeller (mm)

　　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.

XBD fire pump specifications and parameters

The specifications and parameters of XBD fire pumps are very diverse, which makes it difficult for people to identify them. Moreover, strict selection is usually required to ensure the normal use of the equipment, while Sanli Water Supply has detailed selection standards and parameter introductions.
