When purchasing booster pump, you first need to consider the reason for insufficient water pressure. If the house is too old and the water pressure is too low, you can use booster pump. However, if the water pressure is low due to pipeline aging and too many right angle elbows, the effect of increasing the pump is limited.

明白使用状况

Understand usage

增压泵选型需根据使用现场来决定，购买前应该先了解家里管路长短，管径大小，可能的弯头数量，以及需要提供的出水量等。这样才能在购买咨询的时候不至于茫然与精 准购买。

The type selection of booster pump shall be determined according to the use site. Before purchase, you should first understand the length of pipeline at home, the size of pipe diameter, the number of possible elbows, and the water output to be provided. Only in this way can we not be at a loss and buy accurately when purchasing consultation.

辨别产品性能

Identify product performance

衡量水泵性能的好坏，功率大小并不重要，而是机组效率。在同等扬程、同等流量的情况下，功率小的效率高，也就是说性能好。水泵有高扬程流量和额定扬程流量的标注方法，市场上大多数水泵都以高扬程流量来标注，有些厂家水泵的标注很离谱，如普通的90w和120w铜泵头增压泵，标准功率为80w和120

To measure the performance of the water pump, the power is not important, but the unit efficiency. In the case of the same head and the same flow, the efficiency of low power is high, that is, the performance is good. The water pump has the marking method of high head flow and rated head flow. Most water pumps in the market are marked with high head flow. The marking of water pumps of some manufacturers is very outrageous, such as ordinary 90W and 120W copper pump head booster pump, with standard power of 80W and 120

算好确定扬程

Calculate and determine the lift

要选择多少米扬程的水泵，其实以额定扬程为好(可以超出额定扬程的20%左右(管道拐弯多时需要增加扬程)，额定扬程范围请看商品图片描述图示)，大扬程只表示能达到的压力，若要抽上到大扬程的高度可以说已经是没有水出的了。

To select a pump with a lift of several meters, in fact, the rated lift is better (it can exceed about 20% of the rated lift (the lift needs to be increased when the pipeline turns for a long time). Please refer to the description diagram of the commodity picture for the range of rated lift). The large lift only indicates the pressure that can be reached. If you want to pump to the height of the large lift, it can be said that there is no water out.

了解产品功能

Understand product features

增压泵产品的功能有自吸、恒压、变频、过热保护、干转保护、全自动等功能特点，一般家用增压需要选择全自动、热过载保护与干转保护功能这三个基本功能的。这样使用的时候你才会感觉便捷，且机器性能才稳定，使用寿命更持久。如泽德的增压泵就是具有自吸、干转保护、热过载保护、全自动增压等功能。

The functions of booster pump products include self-priming, constant pressure, frequency conversion, overheat protection, dry turn protection, full-automatic and other functional characteristics. Generally, household booster needs to choose three basic functions: full-automatic, thermal overload protection and dry turn protection. In this way, you will feel convenient, stable performance and longer service life. For example, Zede's booster pump has the functions of self-priming, dry rotation protection, thermal overload protection, full-automatic pressurization and so on.
