Booster pump and circulating pump, as the name implies, have different performance, in the installation location, scope of application, operation and control and other aspects have their own characteristics, with obvious differences.
1. Working principle
Circulation pump: circulation refers to the function of the pump, centrifugal refers to the structure of the pump, both are completely two concepts. The working principle of the circulating pump is to circulate the water, and the pump used is called the circulating pump. For example, the hot water in the water heating pipe is circulated by the circulating pump.
Booster pump: first fill the booster pump with liquid, and then start the centrifugal pump. The impeller rotates rapidly. The blade of the impeller drives the liquid to rotate. When the liquid rotates, it flows to the outer edge of the impeller relying on inertia. At the same time, the impeller sucks liquid from the suction chamber. This force works on the liquid, so that the liquid gets energy and flows out of the impeller. At this time, the kinetic energy and pressure energy of the liquid increase.
2. Installation position
The booster pump is generally installed on the water inlet pipe. After a section of the original pipe is cut off, the pump can be connected to the pipeline in series; the circulating pump needs to be installed on the return water pipe to pressurize the system pressure to assist its circulation. Cut a section of pipeline with scissors and connect the pump to the pipeline in series.
3. Scope of application
Booster pump is generally used in central heating system, and the small difference between solar energy and water pressure leads to low water pressure, and the water pressure of water heater is small, which needs to be pressurized; the circulating pump is mainly aimed at self heating users, or medium and large household heating system circulation, floor heating hot water circulation. If the inlet water temperature is acceptable and the outlet water temperature is low, the installation of circulating pump can solve the problem. However, if the inlet and outlet water temperatures are low, it is necessary to find out the reason why the water is not hot.
4. Supercharging strength
Booster pump mainly solves the problem of small water pressure, which belongs to the type of pump with small pressure. This is mainly determined by the structure of the water pump, the booster pump is pressurized by centrifugal force; and the circulating pump has higher pressure than the booster pump, which can drive the circulation of the whole heating system.
5. Product operation
Booster pump is mostly automatic control, that is, the switch is automatic water flow switch control, as long as there is water flow switch automatic start, no water flow automatically closed; circulation pump is mostly manual control, need to manually start the switch, to achieve the pump on and off operation.
Because of the above differences between booster pump and circulating pump, users must pay attention to distinguish and distinguish them in the process of purchase and use, so that both pumps can make the best use of everything and fit for their place. Otherwise, it will be difficult to meet their own needs and even damage the overall system. When you are not sure which type of pump to buy, try to consult professionals and listen to their purchase suggestions.
There are many hidden dangers in the heating pump. The heating pump in the market is generally driven by the power supply, so the pump body can not be drenched with water, exposed to the sun and frozen. In the process of use, it will emit heat, so it needs to be installed in a ventilated place and can not be wrapped with cloth to prevent fire.
Due to the impurities in the water, such as rust and scale, these impurities accumulate in the pump for a long time, which can easily block the impeller or cause the motor to sound louder and louder, which will affect the normal use of the pump and people's home life, and greatly reduce the service life of the pump.
From the above analysis, it can be seen that many families have come up with the method of installing pump or circulating pump to solve the problem of floor heating is not hot. However, due to the different performance and application scope of these two pumps, users should pay attention to and distinguish them when purchasing and installing. Of course, if your home is a central heating user, you need to think twice before you install it. You must not have your own heating hot or your neighbor's heating cold. It's better to ask professionals to find out the cause of the heat, adjust measures to local conditions, and ask relevant units to adjust and repair.
