Fire Pump Maintenance Knowledge

In the daily maintenance of the fire pump, we need to meet the following requirements: we need to ensure that the water inlet and outlet pipes, the various components of the controller, and the diesel engine system can work normally, and ensure that the power part is firmly connected to the water pump. We also need to check the opening status of the pump room, fire pump system, and various valves to ensure that the pump room has good heat dissipation conditions and that the components of the pump are in normal working condition.
