Product Overview
The EDJ series is a complete set of fire pump units, typically forming an automatic fire water supply system. This system comprises the following core components:
Main pump: driven by an efficient electric motor
Standby pump: equipped with diesel engine drive
Pipeline pressure compensating pump: used to maintain the pressure of the pipeline network
control system
Two controller configuration schemes are provided:
A. Standalone controller
Flexible installation
Easy to maintain
B. Integrated controller
Installed on skid-mounted equipment
Small space occupation
equipment accessories
The complete equipment set includes the following accessories:
discharge valve
Common manifold
pressure gauge
flow meter
Various types of connecting flanges
working principle
Basic operating mechanism
The system monitors the pressure of the pipeline network in real-time through pressure sensors to maintain the pressure within a set range. The specific workflow is as follows:
Normal operating state
The pressure of the pipeline network is maintained between P1 (low pressure) and P2 (high pressure)
The pressure maintenance pump automatically starts and stops according to pressure changes
Pressure drop treatment
When the pressure drops to P1, the pressure maintenance pump automatically starts
After the pressure rises back to P2, the pressure maintenance pump automatically stops
High-flow demand response
When the pressure further decreases to P3 (the lowest pressure):
a) Automatic start of electric pump
b) The pressure rebounds to Pw (water supply pressure)
c) Meet the demand for fire-fighting water
Response to power failure
In the event of a main power supply interruption or electric pump malfunction:
a) The pressure continues to decrease until reaching P4 (ultimate pressure)
b) Automatic start of diesel pump
c) The pressure rebounds to Pw
d) Restoration of fire water supply
