High Power Output and Fuel Efficiency Diesel Engine Fire Fighting Pump Set

High Power Output and Fuel Efficiency Diesel Engine Fire Fighting Pump Set

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

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
