增压泵和循环泵，顾名思义具有不同的性能，在安装位置、适用范围、操作操控等方面上都有各自的特征，具有明显的区别。
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.工作原理
1. Working principle
循环泵：循环指泵的作用而言，离心是指泵的结构而言，两者完全是两个概念。循环泵的工作原理要将水循环起来所用的泵就叫循环泵，例如水暖供热管道中的热水是靠循环泵循环起来的。
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.
增压泵：先将增压泵内充满液体，然后启动离心泵，叶轮快速转动，叶轮的叶片驱使液体转动，液体转动时依靠惯性向叶轮外缘流去，同时叶轮从吸入室吸进液体，这个力对液体做功，使液体得到能量而流出叶轮，这时液体的动能与压能均增大。
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.安装位置
2. Installation position
增压泵一般安装在进水管道上，在原有管道上剪断一段后泵串联到管路上即可;循环泵需安装在回水管上，增压系统压力，以助其循环，用剪子剪断一段管道，泵串联到管路上即可。
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.适用范围
3. Scope of application
增压泵一般用在集中供暖系统上，和太阳能落差小导致水压小，以及热水器水压小，需要增压的情况下;循环泵主要针对的是自采暖用户，或者中大户型家庭取暖系统循环、地暖热水循环使用。如果进水温度可以、出水温度较低，安装循环泵就可以解决问题，但是如果进回水温度都低，那么需要先查找不热的原因。
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.增压强弱
4. Boosting strength
增压泵主要解决水压偏小的问题，属于压力偏小的类型泵。这主要是由水泵结构决定的，增压泵是靠离心力增压;而循环泵相较增压泵压力较大，可以带动整个供暖系统的循环。
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.产品操作
5. Product Operation
增压泵多是自动控制，即开关是水流自动开关控制，只要有水流动开关自动启动，没有水流动自动关闭;循环泵大多是手动控制，需要人为开动开关，实现水泵接通运转和停止运转。
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.
由于增压泵和循环泵存在以上诸多区别，因而在采购和使用过程中，用户一定要注意进行辨别和区分，使两种泵都物尽其用、适得其所，否则将很难满足自家的需求，甚会损害整体系统。在您没有把握选购哪种水泵的时候，尽量咨询人士，听听他们的选购建议。
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.
暖气泵存在诸多隐患，现在市场的暖气泵一般是靠电源带动，因而泵体不能被淋到水，不能被太阳暴晒，不能被冰冻结。在使用过程中，会散发热量，因而需要安装在通风处，不能用布包裹住，以防引发火灾。
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.
由于水中含有杂质，比如铁锈和水垢，这些杂质长期在水泵中积累，容易卡死叶轮或者导致电机声音越来越大，从而影响水泵的正常使用和人们的家居生活，也会大大缩减泵的使用寿命。
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.
从以上的分析可知，在解决地暖不热的问题上，很多家庭想出安装泵或者循环泵的方法，但是由于这两种泵的性能、适用范围不同，因此在选购和安装时需要用户加以注意和区分。当然，如果您家是集中供暖用户，在安装之前需要三思而后行，千万不能出现自家暖气热了、周围邻居暖气凉了的情况。更好请人士查找不热的原因，因地制宜的进行解决，以及请相关单位给与调节和维修。
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.
