Long Axle Fire Pump

Fire pumps, as the name implies, are pumps used for firefighting. These are imported products that come in various types depending on their classification methods. Known for their fully sealed, leak-free, and corrosion-resistant features, they are widely used in environmental protection, water treatment, and firefighting sectors. They are ideal for pumping various liquids and for creating leak-free, pollution-free civil workshops and factories. The types of pumps are similar, differing only in head and flow rate. When installing fire pumps, it must meet the requirements of the standard.

1. Prior to installation, the fire pump should be verified for compliance with the product certification, ensuring that its specifications, model, and performance match the design requirements. Installation should be conducted 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 positions of the fire pump should be reviewed.

3. Prior to the installation of fire pumps, the distances between the fire pumps and between the fire pumps and the walls or other equipment should be reviewed, and they should meet 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 base. Its diameter should not be smaller than the diameter of the fire pump's suction opening, and control valves without reliable locking devices should not be used. Groove-type or flanged valves should be used for the control valves.

5. When the fire pump and 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 pockets or leakage on the horizontal section of the suction pipe. When changing diameters, use eccentric reducers and ensure a level top connection.

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 plug should be installed between the pressure gauge and the buffer device; if there are no design requirements for the pressure gauge range, it should be twice to 2.5 times the system working pressure.

8. The vibration isolation device of the fire pump and the installation of the flexible connection of the inlet pipe should comply with design specifications, and there should be product instructions and installation/user manuals.
