9. Clean the exterior of the fire pump and its components with a damp cloth.

10. Test the fire pump to ensure its proper operation.

Learn how to properly integrate fire pumps with sprinkler systems to ensure consistent pressure, compliance with NFPA standards, and reliable fire protection.

Safety precautions include wearing appropriate protective gear, ensuring proper ventilation when operating gasoline or diesel-powered pumps indoors, following proper procedures for fueling and starting the pump, and maintaining a safe distance from flames and hazardous materials.

A multistage pump is a multistage centrifugal pump in which two or more impellers are installed on the pump shaft and connected in series to work together. A horizontal multistage centrifugal pump refers to a multistage pump in which centrifugal pumps with two or more impellers are combined. The multistage centrifugal pump is characterized by high efficiency and energy saving, wide range of use, special purpose, stable operation, long service life, convenient installation and maintenance, etc.

The diesel engine (can be equipped with a clutch) is combined with the fire pump through a highly elastic coupling to form a fire pump unit. The unit also includes diesel tanks, cooling water tanks, fans, control panels (for automatic units) and other components.
When the unit is automatically controlled, the split or diesel engine automatic control cabinet (programmable) realizes the automatic start, input, and automatic switching of the system (switching from the electric pump group to the diesel engine pump group or from this group of diesel engine pump groups to another group of diesel engines) pump set), automatic protection (diesel engine overspeed, low oil pressure, high water temperature, three start failures, low oil level, low battery voltage and other alarm shutdown protection) and other functions, and can also interface with the user’s fire center or automatic fire alarm device, Realize remote monitoring.

The diesel engine fire pump needs to be aimed at the occasion of large flow and high head fire water material supply, and it has good characteristics of the starting system for diesel automobile engines, fast starting development speed, strong overload capacity, no need for standby operation, and effective energy saving. Diesel engine firefighting pumps have complete performance and a wide range. Single-stage single-suction pumps, multi-stage single-suction pumps, self-priming pumps, long-axis pumps and other pumps can be used, and they can also be used in combination and in parallel. The flow and pressure ranges are wide. Diesel fire-fighting pumps are widely used in fire-fighting system water supply in various occasions of industrial and mining production enterprises such as data warehouses, docks, airports, petrochemicals, and power plants.

The function of the diesel fire pump is very powerful. We can set the control time during use, for example: preheating in advance, pre-lubrication or timing start. The use of high technology has made some complicated and time-consuming things easier. The preheating setting in advance has greatly reduced the preparation time for rescue, allowing firefighters to rescue at the first time. In the face of disasters, time is money, time It is life.

In the fire fighting pipeline pump, according to the different installation methods can be divided into vertical fire pumps and horizontal fire pumps, many people have questions about these two common pumps, what is the difference between the two? Shanghai Xizhiquan will explain the difference between horizontal and vertical pumps.

Obviously, different installation methods take up different space. Vertical pipeline pumps are installed vertically, covering a relatively small area, and vertical fire pumps do not require a foundation, while horizontal fire pumps need to be equipped with a base.

According to the different structures of the two pumps, it can be concluded that there is also a certain difference in the ease of maintenance of the two types of fire fighting pipeline pumps. The impeller of the vertical fire pump needs to be dismantled from top to bottom, which makes maintenance more difficult; the horizontal fire pump only needs to have the inlet pipe removed so that the impeller can be overhauled, which is relatively simple.

Due to the different inlet and outlet pipe directions, the pipeline connection between vertical and horizontal is also different. As the vertical pump is a bottom-up structure, while the horizontal fire pump is longitudinally arranged on the base, so the motor of the vertical pump and the pump body are connected in the form of sub-mouth connection, while the horizontal pump needs to use couplings to connect with the motor, and the horizontal pipeline pump needs to be corrected regularly.

The EDJ Diesel Engine Fire Pump System is a powerful and reliable firefighting equipment designed for fire suppression and emergency rescue operations. It boasts high-performance capabilities in water extraction and pressure delivery, enabling rapid supply of large volumes of water. The system operates independently, ensuring its reliability even in challenging situations.

CDL stainless steel vertical multistage pump is especially suitable for boiler feed water, and can also be widely used in pressure vessel water supply, hot water circulation, high-rise building water supply, farmland irrigation, fire pressurization, hydraulic flushing, food, brewing, medicine, chemical industry, aquaculture , environmental protection, chemical process and machine tool supporting industries, as the power equipment for water supply and drainage.

The diesel engine fire pump is usually used as a backup facility, so it will only start automatically when the fire signal comes, and when the electric water pump fails or the power supply is cut off. When it has a device for starting the pump at ultra-low pressure, its matching electric water pump control cabinet should also have a device for starting the pump at ultra-low pressure, and the lower limit of the two pumps should have a certain pressure difference.

Fire pump set test mainly tests pressure and flow. In all pump products, pressure and flow and two extremely important parameters. Pressure determines the pumping height or water delivery height of the pump, and flow determines the hourly water output of the pump. In addition. Product power and voltage, as well as environmental testing is also essential.

The fire pump is usually equipped with a local control cabinet. The control cabinet does not have a transfer control switch for automatic and manual conversion, but the automatic control loop leaves start and stop contacts, which are connected to the fire alarm system control module. In addition, according to the relevant regulations, the system using the bus linkage control should also be set in the fire control room with buttons that can directly start and stop the pump. When the fire alarm system receives the signal of the fire hydrant start pump button, the control module automatically starts the fire pump and collects its feedback signal.

What is Water Hammer?
A sudden increase in water pressure caused by rapid valve closure or pump shutdown, leading to:

Pipe vibrations and damage.
Pressure surges that can exceed system limits.
Component wear and potential pump failure.
Prevention Methods:
Use slow-closing valves to prevent sudden pressure changes.
Install surge arrestors or expansion tanks to absorb pressure spikes.
Ensure proper pump start/stop sequences to reduce shock loads.

Safety measures include regular training for personnel, ensuring proper ventilation in pump rooms, and following manufacturer guidelines for maintenance and operation.

In urban areas, where water supply systems may be complex and highly interconnected, fire pumps play a crucial role in ensuring resilience and reliability. These pumps help maintain adequate water pressure and flow across different zones within the city, especially during peak demand periods or in the event of a fire. Fire pumps are often integrated into municipal water systems, providing additional pressure support for firefighting efforts and ensuring that water can be delivered quickly to where it is needed most. In some cases, fire pumps are also used to support the overall stability of the water supply network by compensating for pressure drops caused by infrastructure issues or increased usage.
