The diesel engine fire pump is usually used as a backup facility. It will only start automatically when the electric water pump fails or is powered off when the fire signal comes. When equipped with an ultra-low pressure pump starting device, the matching electric pump control cabinet should also be equipped with an ultra-low pressure pump starting device, and the lower limit of the pump should have a certain pressure difference. Of course, it is also possible to design a control system that is more suitable for customer needs according to customer requirements.

Strategies include:

Water Recycling: Implement systems to recycle water used during pump testing, minimizing wastage.
Eco-Friendly Testing Methods: Use methods that reduce water consumption, such as flow meters that simulate flow conditions without discharging large volumes of water.
Regular Maintenance: Keep the pump in good working order to reduce the frequency and duration of testing needed.
Environmental Monitoring: Monitor and manage the environmental impact of testing activities, ensuring compliance with local environmental regulations and standards.

First, what’s a water pump? It’s a device used to transport liquid, pressurize the liquid, and make the liquid from the first liquid position to the high liquid position. The first water pump constructed by the Chinese is called” water windmill”. latterly, around 300 BC, the emergence of the” Archimedes screw pump” is more analogous to ultramodern pumps. In addition, the following introductory knowledge points are what you must understand.
1. Centrifugal pump

Centrifugal pump is the most common type of pump. In simple terms, the working principle of centrifugal pump is to rotate the impeller to drive the liquid under the action of centrifugal force. The liquid leaves the impeller and enters the volute. As the inflow passage of the volute gradationally expands, the fluid haste slows down, and the pressure rises continuously, and eventually it’s discharged through the conduit.
2. Impeller
The impeller is one of the main factors in the water pump, and it’s the core element that transmits mechanical energy to the liquid. The impeller is substantially divided into three types open type,semi-open type and closed type. The material conditions for the impeller are high, wear resistance is needed, and the manufacturing process is good.

3. Cavitation

Cavitation is the conformation of numerous bitsy recesses when the liquid connections the liquid under high- speed inflow and pressure, and gradationally expands into grottoes when serious, and cavitation frequently occurs in the impeller and pump covering.

The fire pump is mainly a kind of pump equipment used for fire emergency, and its function is to transport the water source to the fire scene for fire fighting. In life, fire pumps are widely used in various buildings, such as factories, docks, warehouses, ports and other places, and are important equipment for fire emergency.

The dual-power fire pump is driven by a diesel engine. When the power grid cannot meet the requirements, the diesel engine can be used to drive the water pump to ensure that the unit can reach the running state.

Jockey pumps should be inspected regularly, with routine checks typically performed monthly. The inspection includes checking pressure settings, verifying proper operation, and inspecting for any leaks or damage. Ensuring that the jockey pump functions correctly helps maintain system pressure and prevent unnecessary wear on the fire pump.
