Description

Product Applications

  • Secondary side circulating water systems in central heating systems
  • Chilled water and cooling water circulation systems in central air - conditioning systems

High - efficiency and Energy - saving
The Dongfang DFJN intelligent high - efficiency circulating unit is composed of high - efficiency single - stage pumps in a combination of large, medium and small sizes, multifunctional filters, flow monitoring systems, plate heat exchangers (for central heating applications), intelligent control systems, complete sets of accessories, etc. It uses a frequency converter from a joint - venture brand. Through a programmable logic controller (PLC), it conducts variable - frequency speed regulation on multiple pumps with different flow rates and combines pumps of different sizes, achieving remarkable energy - saving effects.

01 High - efficiency Water Pump

  • A combination of large, medium, and small high - efficiency water pumps offers a wide high - efficiency range. The unit can automatically activate one or multiple pumps based on the system's flow requirements. With a wide high - efficiency range, it always operates within the high - efficiency zone, making the system more energy - efficient.
  • It features a high - efficiency hydraulic model and is optimized using CFD (Computational Fluid Dynamics) design.

02 Low - resistance Pipe Valves

  • Full - bore non - slamming low - resistance check valve.
  • Adopting laser - cut materials, with precise dimensions. The valve port has a smooth surface for low resistance.
  • Full - bore straight - through flange butterfly valve.

03 One - to - One Frequency Conversion

  • Each water pump is equipped with a dedicated frequency converter, which can operate according to parameters such as outlet pressure, differential pressure, temperature, and flow rate. The terminal can transmit data to adjust the outlet pressure in real - time. While ensuring the stable operation of the frequency converter, it also enables timely adjustment for users.
  • With the one - to - one dedicated frequency converter, the frequency converter can operate according to actual needs to accurately adjust the flow and pressure, which can effectively solve the problem of excessive flow and low user occupancy rate, saving the occupied space.
  • The control cabinet is a special control device for the chilled water system. It can collect power grid parameters, operating status, and fault information. The equipment can automatically operate in the high - voltage area. It has the advantages of stable operation and can promptly respond to user needs and handle fault information. Additionally, a redundant control unit can be added to enhance the reliability of the entire chilled water system.

High Reliability
Anti - corrosion impellers, multifunctional filters, imported components, one - time - formed


01 High - standard Hardware

  • Coating thickness measurement ensures the equipment is corrosion - resistant and has a long lifespan.
  • The equipped inverters feature a high protection level (IP55), are dust - proof, have thickened PCB coatings, and exhibit high reliability.
  • Equipped with imported brand components.
  • Equipped with imported brand programmable logic controllers.

02 Multifunctional Filters and Corrosion - resistant Pipelines

  • Pump sets, bases, low - resistance pipe valves, and control cabinets are pre - fabricated in the factory and assembled modularly. Overall testing is completed before leaving the factory to ensure the overall performance of the products.
  • The 304 - stainless - steel pipelines undergo pickling, passivation, and electrolytic polishing treatments to offset the impact of welding on the pipelines and enhance their corrosion - resistance.
  • Multifunctional filters with functions like scale removal, filtration, and back - flushing, along with low - resistance pipe valves, effectively ensure the stable and efficient operation of the system.

High Integration Degree
The equipment adopts an electromechanical integrated design. Components are modularly integrated on a common base and undergo overall debugging before leaving the factory. There is no need for on - site fabrication, which saves installation time and reduces installation costs. The equipment can be put into operation once it is powered on and supplied with water on - site, reducing installation and debugging costs.

01 Electromechanical Integrated Design
The unit features an electromechanical integrated design. The pump set and the frequency converter are mounted in a back - hung manner, and the control cabinet is much smaller in size. It is more compact than traditional units, occupying less floor space.

02 Integration of Various Functional Configurations
For central heating applications, a plate heat exchanger can also be integrated.
