The EDJ fire pump set is composed of a fire pump, a dual-shaft extension motor and a diesel engine. One end of the output shaft of the dual-shaft extension motor is connected to the input shaft of the fire pump, and the other end of the output shaft of the dual-shaft extension motor is connected to the input shaft of the fire pump. One end of a clutch is connected, and the other end of the clutch is connected with the output shaft of the diesel engine. The fire water pump, the double-shaft extension motor, the clutch and the diesel engine are all fixed on the base. The double-shaft extension motor, the clutch and the diesel engine are respectively electrically connected with a control circuit through the action driving circuit. With dual-power fire pump, there is no need to configure a second fire pump, reducing floor space and manufacturing costs.

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.

Jockey pumps are smaller pumps that maintain pressure in the fire protection system between tests and activations. They prevent pressure loss in the system and ensure that the fire pump doesn’t start unnecessarily. Jockey pumps are crucial for system reliability.

Yes, fire pumps can be essential in remote or rural areas where a dedicated water supply for firefighting may not be readily available. They can draw water from natural sources or dedicated water tanks.

The electric pump of the EDJ fire pump group is the main pump, the diesel engine pump is the backup pump, and the jockey pump plays a role in the stabilization of the whole system. When the electric pump fails or the mains is cut off, the control cabinet will receive electricity from the The signal from the contact pressure gauge will start the diesel engine pump within 5 seconds, and reach the rated working condition within 20 seconds to ensure the normal operation of the fire extinguishing work.

The fire pump is mainly used for water delivery in the fire protection system. As an indispensable tool for the fire protection system, the fire pump has the characteristics of simple structure and stable performance. Due to these advantages of high performance and low energy consumption, the safety and efficiency of the fire pump are far ahead of the pipeline tools of the same purpose.

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.
