Electric fire jockey pump

Electric fire jockey pump is an auxiliary pump that is especially designed for the fire extinguishing system and mainly used for maintaining the system pressure to prevent frequent start of the main fire water pump. Professional introduction to vertical centrifugal constant pressure pump:

Functions and effect

1. Maintain system pressure: Vertical centrifugal constant pressure pump can start automatically as the system pressure declines to replenish the system pressure, ensuring that the system pressure is always within the preset range and preventing the main pump from starting by mistake due to pressure fluctuations.

2. Energy conservation and emission reduction: By reducing frequent start of the main pump, the energy consumption and device wear have been lowered, and the service life of the main pump and the whole fire extinguishing system has been extended.

3. System monitoring: Vertical centrifugal constant pressure pump can also be used for detecting and monitoring the pressure condition of the fire extinguishing system on a regular basis to ensure normal operation of the system.

Structure and composition

Vertical centrifugal constant pressure pump mainly consists of the following parts:

-Pump body: Pump body is installed vertically, so it covers a small land area and has a compact structure, and usually consists of efficient centrifugal impellers and pump casing to achieve high pressure at low flow rates.

-Motor: Motor used for driving the pump body is vertically installed, so its structure is compact, and it is usually configured with protective measures to adapt to different environmental conditions.

-Control system: This system consisting of the pressure switch, pressure gauge and automatic controller is used for real-time monitoring and regulation of the system pressure to ensure the pump starts and stops when needed.

-Pipes and valves: They are used for connecting the pump body and the trunk pipe of the fire extinguishing system to control the water flow direction and flow rate.

Working principle

The working principle of vertical centrifugal constant pressure pump is based on pressure control. When the system pressure declines to the preset minimum value, the pressure switch triggers the pump to start, and then the pump injects water into the system through the revolving impeller to recover the system pressure. When the system pressure recovers to the preset maximum value, the pressure switch will work to shut down the pump. The entire process is automatic, ensuring the system is always within the normal working pressure scope.

Application scenarios

Vertical centrifugal constant pressure pump is widely applied to types of fire extinguishing systems that require efficient and reliable pressure maintenance, such as:

-High-rise buildings (office buildings, and residential buildings)

-Industrial facilities (factories and warehouses)

-Commercial buildings (shopping centers and supermarkets)

-Public facilities (schools, hospitals and airports)

Advantages and characteristics

-Small land area coverage: The vertical design saves the installation space, so it is very suitable for occasions with a limited space.

-Stable operation: Design of the centrifugal pump enables it to operate stably with small vibration and low noise.

-Convenient maintenance: The vertical structure is convenient for maintenance, inspection, and repair, reducing the shutdown time.

-Efficient energy conservation: The efficient centrifugal impeller design improves the working efficiency of the pump and reduces energy consumption.

Installation and maintenance

Installation and maintenance of the vertical centrifugal constant pressure pump should follow the following principles:

-Correct model selection: Appropriate pump model and specification should be selected according to the system requirements to ensure the pressure and flow rate of the pump can meet the system demands.

-Position selection: The pump should be installed at a dry and ventilated place to facilitate operation and maintenance.

-Regular inspection: The pump body, motor and control system should be inspected on a regular basis to ensure all parts work normally and prevent potential faults.

-Emergency treatment: An emergency treatment plan should be established to ensure the system can start the main fire water pump timely when the constant pressure pump does not work.

Through reasonable installation and maintenance, vertical centrifugal constant pressure pump can operate steadily for a long time to provide the fire extinguishing system with reliable pressure maintenance guarantees.
