Traditional heating units have complex systems, numerous equipment, high maintenance costs, large initial investments, and occupy a lot of space. In some cases, heat loss during heat exchange occurs, and the heating standards for buildings may not be met. Increasing the heat - exchange area or raising the network pressure would significantly increase investment, but our DFGZL high - rise direct - connection heating unit offers a solution.This unit combines the high - zone heating system and low - zone heating system in high - rise buildings directly. It overcomes many technical drawbacks of traditional high - rise building heating equipment. Without dedicated high - zone boilers, water tanks, and it directly pressurizes the heat - supply water from coal - fired sources to the high zone, avoiding a large amount of heat loss in the heat - exchanger system. It features a simple structure, low equipment investment, high heat efficiency, and fully automatic operation. This heating system is widely applied in high - rise building heating.01 High - efficiency Water PumpsThe unit can automatically activate pumps for variable - frequency operation based on the system flow demand, making the system more energy - efficient.It has a high - efficiency hydraulic model optimized by CFD (Computational Fluid Dynamics) for hydraulic model optimization.02 Low - resistance Pipe ValvesFull - bore non - slamming low - resistance check valves.Laser - cut materials and robot welding ensure smooth valve ports and low resistance.Full - bore quick - closing butterfly valves.03 Direct - connection to Heat - supply Company Pipeline Network, Pressure Boosting, Small FootprintWithout dedicated boilers, water tanks, heat exchangers, pressure - reducing valves, expansion tanks, and water treatment systems, the system is simple and the investment cost is low.Users can directly use the high - temperature network water for heating, eliminating the heat - exchange process, improving heat - energy utilization, and coal - burning temperature. Equipped with filters to ensure the quality of the supplied water and prevent water - inlet network blockage, thus significantly enhancing the heating effect.The unit operates in a variable - frequency mode, making full use of the external network water pressure, resulting in significant energy savings.    DFGZL High ReliabilitySound quality management, after - sales service system, and product craftsmanship01 High - standard HardwareCoating thickness measurement ensures the equipment is corrosion - resistant and has a long lifespan.The equipped frequency converters 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 Sound Quality Management and After - sales Service SystemThe company has an IoT - Net certificate and a CTEAS certificate.Based on its quality management and after - sales service system, the company conducts full - process quality control over four major processes: resource management, management responsibility, product realization, and measurement, analysis, and improvement. It promotes product standardization and institutionalization, ensuring product reliability and the timeliness of after - sales service.03 Mature Product CraftsmanshipManufactured using robots and numerically - controlled equipment, surpassing traditional welding, cutting, and bending techniques, ensuring product quality consistency and stability.Working EnvironmentPower supply: 380V×(100±5)%, three - phase five - wire system;Ambient temperature: 4°C ~ +40°C (appropriate measures must be taken if beyond this range);Relative air humidity: 20% ~ 90% (at 20°C), no condensation;Installation site should be free of conductive dust, gases that can corrode metals and damage insulation, and areas with explosion hazards;Altitude should not exceed 1000m. When it exceeds, control components should be adjusted accordingly.Selection of the UnitSelection of the Pressure - boosting Circulating Pump:Head of the Pressure - boosting Pump (m)H=Hj?Hw+Hn+HaHj: Geometric height from the pump to the top of the system (m)Hw: Resistance loss of the indoor system (m)Hn: Dynamic water - line height of the heat - network supply water at the pump location (m)Ha: Safety margin, can be taken as [a specific value, which is not given in the original content] (m)Flow Rate of the Pressure - boosting Pump (m3/h)G=kρ(t1?t2)0.86Qk: Additional coefficient, can be taken as 1.1Q: Heat load of the high - zone system (W)t1: Supply water temperature (°C)t2: Return water temperature (°C)ρ: Density of the supply water (kg/m3) Determine parameters such as the model of the pressure - boosting circulating pump and the motor power based on the above - mentioned head and flow rate.Production Plant                      Main Processing Equipment                  Electrophoresis and coating line                Company Profile
