The difference between direct heat pump and circulating heat pump

The difference between direct heat pump and circulating heat pump

Simply understood, cold water from the outside enters the heat pump unit and comes out with 60 ℃ hot water, and there is no small water tank inside the equipment. Due to the absence of a circulating water pump between the insulation water tank and the equipment, the start and stop of the equipment are completely controlled by the high and low water level controllers of the water tank.

Maintenance and upkeep of circulating water pumps

Maintenance and upkeep of circulating water pumps

The maintenance and upkeep of circulating water pumps should be viewed from both daily and operational aspects: (1) Daily maintenance and upkeep 1. Keep the equipment clean, dry, oil-free, and leak free. 2. Check whether the running sound of the circulating water pump is normal, whether there is vibration or leakage every day, and promptly handle any problems found. 3. Check whether the oil level in the suspension oil chamber of the centrifugal pump is suitable every day, and it must be maintained at 1/3 and 2/3 of the oil level gauge. 4. It is strictly prohibited for the circulating water pump to work when the liquid in the water tank (barrel) is evacuated, as the circulating water pump not only vibrates violently during the evacuation state, but also affects the pump's lifespan. Therefore, special attention must be paid. 5. Metal objects and flexible substances such as rubber, cotton yarn, and plastic cloth are strictly prohibited from entering the circulating water pump, in order to avoid damaging the flow passage of the water pump and blocking the impeller passage, which may prevent the pump from working properly. 6. Regularly check the concentricity of the claw coupling. 7. The circulating water pump with packing seal should regularly check the leakage rate at the packing box, and the normal leakage rate at the packing box should be 10-20 drops per minute; Otherwise, the tightening position of the packing gland should be adjusted.
