[0002] With the development and prosperity of society, fire safety in houses, offices and public places is becoming increasingly important. As an indispensable fire-fighting equipment, fire pumps have extremely high reliability requirements to ensure fire safety. Existing fire pumps are generally composed of a power machine, a bracket and a water pump. In order to achieve the effect of energy saving and water saving, electric water pumps are currently equipped with a pressure controller in their pipelines. Once the water pressure is lower than the set value, the controller will connect the water pump power supply to start the water pump to work, thus achieving the purpose of automatic control.
