Booster pumps and circulation pumps, as the name suggests, have different performance, and have their own characteristics in terms of installation position, scope of application, operation and control, with obvious differences.
1. Working principle
Circulation pump: Circulation refers to the function of the pump, while centrifugation refers to the structure of the pump. The two concepts are completely different. The working principle of a circulating pump is that the pump used to circulate water is called a circulating pump. For example, the hot water in a heating pipeline is circulated by a circulating pump.
Booster pump: First, fill the booster pump with liquid, and then start the centrifugal pump. The impeller rotates rapidly, and the blades of the impeller drive the liquid to rotate. When the liquid rotates, it flows towards the outer edge of the impeller relying on inertia. At the same time, the impeller sucks in liquid from the suction chamber, and this force works on the liquid, causing it to receive energy and flow out of the impeller. At this time, the kinetic energy and pressure energy of the liquid increase.
2. Installation position
Booster pumps are generally installed on the inlet pipeline, and after cutting a section of the original pipeline, the pump can be connected in series to the pipeline; The circulating pump needs to be installed on the return water pipe to boost the system pressure to assist in circulation. Use scissors to cut a section of the pipeline, and the pump can be connected in series to the pipeline.
3. Scope of application
Booster pumps are generally used in central heating systems, where the small drop in solar energy leads to low water pressure, and when the water heater has low water pressure and needs to be pressurized; The circulating pump is mainly designed for self heating users, or for the circulation of heating systems and floor heating hot water in large and medium-sized households. If the inlet temperature is acceptable and the outlet temperature is low, installing a circulating pump can solve the problem. However, if the inlet and outlet water temperatures are both low, it is necessary to first investigate the cause of the overheating.
4. Boosting strength
Booster pumps mainly solve the problem of low water pressure and belong to the type of pump with low pressure. This is mainly determined by the structure of the water pump, and the booster pump relies on centrifugal force for pressurization; Compared to the booster pump, the circulating pump has a higher pressure and can drive the circulation of the entire heating system.
5. Product Operation
Booster pumps are mostly automatically controlled, that is, the switch is automatically controlled by the water flow switch. As long as there is water flow switch, it will automatically start, and if there is no water flow, it will automatically close; Most circulating pumps are manually controlled and require manual activation of the switch to achieve the connection and shutdown of the water pump.
Due to the many differences between booster pumps and circulation pumps mentioned above, users must pay attention to distinguishing and distinguishing between them during procurement and use, so that both pumps are fully utilized and suitable for their needs. Otherwise, it will be difficult to meet their own needs and even damage the overall system. When you are unsure which type of water pump to purchase, try to consult professionals and listen to their purchasing suggestions.
Heating pumps have many safety hazards. Nowadays, heating pumps in the market are generally driven by power, so the pump body cannot be soaked in water, exposed to sunlight, or frozen. During use, heat will be emitted, so it needs to be installed in a ventilated area and cannot be wrapped in cloth to prevent fire.
Due to the presence of impurities such as rust and scale in the water, these impurities accumulate in the water pump for a long time, which can easily block the impeller or cause the motor to sound louder and louder, thereby affecting the normal use of the water pump and people's home life, and greatly reducing the service life of the pump.
From the above analysis, it can be seen that many families have come up with methods to install pumps or circulation pumps to solve the problem of underfloor heating. However, due to the different performance and applicability of these two types of pumps, users need to pay attention to and distinguish between them when selecting and installing them. Of course, if your home is a central heating user, you need to think twice before installing, and never let your own heating get hot or your neighbors' heating get cold. It is best to ask professionals to investigate the reasons for the lack of heat, solve it according to local conditions, and ask relevant units for adjustment and maintenance.
