Precision-Fit for Complex Systems: Application Trends of Horizontal Electric Multistage Pumps in Super High-Rise Fire Protection

Diesel engine fire pump, as a fixed fire extinguishing equipment, has been widely used in fire diversion, especially in emergencies such as no power supply or abnormal power supply, other diesel engines can also be equipped as power engines according to the needs of users.??

The main reason to have a fire pump is to work with the fire protection system in case the water supply does not have sufficient pressure. High structures or large warehouses that carry large amounts of water require the help of a fire pump. It increases the pressure of the water flowing into the fire suppression system, allowing the system to release the maximum amount of water while extinguishing the fire.

There is a combination equipment that uses diesel as fuel for firefighting, but it is usually used as a backup firefighting facility, because it can only be started automatically when the firefighting signal comes, and the electric water pump fails or the power supply is cut off, that is, the diesel engine firefighting pump set. It is very different from the electric fire pump in that it has its own independent power supply and storage system.

The electric fire pump set is an important fire pump equipment, usually in a horizontal state. Each pump group is composed of five parts: front pump, electric motor, hydraulic coupling, main feed water pump, lubricating oil device (including lubricating oil cooler and working oil cooler. In normal state, two sets are running, one There are two standby pumps, and any feedwater pump set can be used as a standby pump. When one of the two running pumps stops due to an accident, the standby pump will be put into operation automatically.

The fire-fighting dual-power water supply equipment produced by Better Technology Co., Ltd. is designed and manufactured in accordance with GB 27898.5-2011 Stationary Fire-fighting Water Supply Equipment Part 5 <>. It meets the requirements of 3CF certification and has obtained 3CF certification for fire protection products.

Fire pumps are rated based on their capacity and pressure performance. The two key ratings are:

Gallons Per Minute (GPM): This rating indicates the pump’s flow capacity and how much water it can deliver per minute. It is essential to ensure that the fire pump can meet the specific flow requirements of the fire protection system.

Pressure (PSI): The pressure rating specifies the force with which the pump can deliver water. Sufficient pressure is critical for effectively propelling water through the fire sprinklers and hoses.

Understanding these ratings is vital when selecting a fire pump for a facility, as it ensures that the pump can meet the specific needs of the fire protection system.

In modern fire protection systems, rapid response to fire incidents is crucial for safeguarding life and property. The Pressure Stabilization and Dual-Function Pump System integrates powerful pressure regulation with dual power sources to ensure that the fire protection system quickly responds and maintains a continuous, stable water supply during emergencies.

This pump system is designed with two power sources—an electric motor and a diesel engine. When the primary power source fails, the diesel engine automatically starts, ensuring uninterrupted operation of the fire protection system even during power outages. Its pressure stabilization system automatically adjusts pressure during operation, ensuring stable water flow for fire suppression and preventing water interruptions due to insufficient or fluctuating pressure, ultimately improving firefighting efficiency.

The intelligent control system further enhances the efficiency of the pump system, allowing users to monitor the system’s status in real-time through a touch panel. The system is easy to operate, and any malfunction is quickly detected and alarms are triggered, activating backup systems to effectively prevent emergency issues caused by system failure.

This pump unit is ideal for applications in high-rise buildings, industrial zones, storage facilities, and other locations with high reliability requirements for fire protection, ensuring that the fire pump can be immediately activated and continue to supply water in any emergency.
