　　Overview of DG85-80X5 Boiler Feed Pump Products at Changsha Water Pump Factory

　　The DG type horizontal multi-stage boiler feed pump is a new product developed by our factory based on the relevant specifications for industrial boiler water supply and drainage. Due to the use of energy-saving products recommended by the state in the hydraulic model, DG type pumps have high efficiency, wide performance range, and better meet usage requirements. Used to replace the old model GC centrifugal pump, it adopts a horizontal and multi-stage pump segmented structure, which ensures safe, stable operation, low noise, long service life, and easy installation and maintenance. This type of pump is particularly suitable for industrial boiler water supply and drainage, cooling water transportation, etc. It can also be used to transport hot water, oil products, corrosive media, etc. by changing the material, sealing form, and adding cooling systems, widely applicable to industries such as petrochemicals, hot water circulation, environmental protection, and pure water transportation. The temperature of the conveying medium is -20 ° C to 150 ° C. The allowable inlet pressure is 0.6MPa.

　　Product features of DG80-80 * 5 boiler feedwater pump

　　1. The hydraulic model is advanced, efficient, and has a wide range of performance.

　　2. The pump runs smoothly with low noise.

　　3. The shaft seal adopts soft packing seal or mechanical seal, which is safe, reliable, structurally simple, and easy to maintain.

　　4. The shaft is a fully sealed structure, ensuring no contact with the medium, no corrosion, and a long service life.

　　Installation of DG80-80 * 5 boiler feedwater pump

　　1. The weight of the pipeline should not be borne on the pump during installation, otherwise it is easy to damage the water pump;

　　2. During installation, the anchor bolts must be tightened, and the pump should be checked at regular intervals to prevent loosening, in order to avoid severe vibration during pump start-up that may affect pump performance;

　　3. Before installing the water pump, carefully check whether there are any hard objects (such as stones, iron sand, etc.) in the pump channel that affect the operation of the water pump to avoid damaging the overcurrent components during the operation of the water pump

　　4. In order to maintain convenience and ensure safety, a regulating valve should be installed on the inlet and outlet pipelines of the pump, and a pressure gauge should be installed near the inlet and outlet of the pump. For high lift pumps, to prevent water hammer, a check valve should also be installed in front of the outlet gate valve to cope with accidents such as sudden power outages and loss of power, thereby ensuring that the pump operates under suitable conditions and extending its service life;

　　5. Pumps used in suction applications should be equipped with bottom valves, and the inlet pipeline should not have too many bends. At the same time, there should be no water or air leakage to avoid affecting the suction performance of the pump;

　　6. To prevent impurities from entering the pump and blocking the flow path, a filter should be installed in front of the pump inlet to improve performance;

　　7. Before installing the pipeline, the rotor components of the water pump should be rotated without friction or jamming, otherwise the pump should be disassembled to check the cause.
