As the name implies, fire pumps are used in firefighting. They are divided into different types according to different classification methods. They are widely used in environmental protection, water treatment, firefighting and other departments to pump various liquids due to their fully sealed, leak-free, and corrosion-resistant characteristics. , It is the ideal pump for creating leak-free, pollution-free civilized workshops and civilized factories.

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 Components :
Electric pump:kinds of end suction pump, split case pump, multistage pump. made of cast iron, stainless steel. Impeller can be bronze.
Diesel pump:Flow is the same with electric pump. It connects the pump set with High elastic coupling or universal joint. It also includes water tank, oil tank, fans, control screen etc.
Jockey pump:horizontal or vertical, small flow, head is higher than electric or diesel pump
Control panel:control the pumps automatically with overload, overcurrent protection

The DJ fire pump equipment is composed of a diesel engine pump and a jockey pump. The diesel engine pump adopts an XA pump with large flow and high lift. The jockey pump adopts a CDL pump. This fire pump set can be used in fire hose and fire hose reel systems, fire sprinkler systems, fire water monitoring systems, fire alarm systems and fire hydrant systems.

Fire pumps are typically started automatically when the fire sprinkler system detects a pressure drop caused by the activation of one or more sprinklers. This automatic start is usually controlled by a pressure switch or controller.

1. Manual Operation: This method involves manually operating the fire pump by an operator who is trained to handle it.

2. Automatic Operation: This method uses an automatic sensing and control system to start and stop the fire pump when needed.

3. Pressure Control: This method uses a pressure switch to monitor the pressure in the system and activate the fire pump when necessary.

4. Flow Control: This method uses a flow switch to monitor the flow in the system and activate the fire pump when necessary.

5. Variable Frequency Drives (VFDs): This method uses a VFD to provide precise control over the speed and torque of the fire pump. This helps to ensure that the fire pump is operating optimally.

6. Remote Monitoring: This method uses a remote monitoring system to provide real-time data on the condition of the fire pump and to allow for remote operation if necessary.

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.
