Fire Pump

Fire pumps, as the name implies, are pumps used for firefighting. These fire pumps are imported products and are categorized into different types based on various classification methods. Known for their fully sealed, leak-proof, and corrosion-resistant features, they are widely used in environmental protection, water treatment, and firefighting departments. They are ideal for pumping various liquids, creating leak-proof and pollution-free civil workshops and factories, and are essential components of fire protection systems. The types of pumps are quite similar; the only differences are in their head and flow rates. When installing fire pumps, they must comply with the standard requirements.

1. Before installing the fire pump, verify the product's certificate of conformity, ensuring its specifications, model, and performance match the design requirements. Installation should be carried out according to the installation and operation manual.

2. Prior to installation, the concrete strength of the pump foundation, vibration isolation device, coordinates, elevation, dimensions, and bolt hole locations of the fire pump should be reviewed.

3. Prior to the installation of fire pumps, the spacing between the fire pumps, as well as between the fire pumps and the walls or other equipment, should be reviewed to ensure it meets the requirements for installation, operation, and maintenance management.

4. The control valve on the suction pipe of the fire pump should be installed after the fire pump is securely mounted on the foundation. Its diameter should not be smaller than the diameter of the fire pump's suction opening, and it should not use a control valve without a reliable locking mechanism. The control valve should be a groove or flange type valve.

5. When the fire pump and the fire reservoir are located on separate foundations and rigidly connected to each other, a flexible connection pipe should be added to the suction pipe.

6. There should be no air bags or leakage on the horizontal section of the suction pipe. When changing diameter connections, eccentric reducer fittings should be used and the pipe tops should be flush.

7. The fire pump outlet pipe should be equipped with a silencer check valve, control valve, and pressure gauge; the main outlet pipe of the system should also have a pressure gauge and pressure switch; a buffer device should be added when installing the pressure gauge. A gate valve should be installed between the pressure gauge and the buffer device; when there are no design requirements for the range of the pressure gauge, it should be twice to 2.5 times the system working pressure.

8. The vibration isolation device for fire pumps and the installation of flexible joints for the inlet pipes should comply with design specifications, and there should be product and installation instructions provided.
