| 1、 弄清水泵使用环境，选择正确的水泵类型（一般就分湿式和干式） 1. Use the environment of Qingshui pump and choose the correct type of water pump (usually wet and dry). 2、 计算水泵所需扬程。有时候碰到客户把平地输送距离也算进扬程了，这是错误的，平地输送距离乘以摩擦系数后，才能算进扬程。 2, calculate the required lift of the pump. Sometimes it is wrong for a customer to count the distance of flat conveying into the head. The distance of flat conveying can only be calculated into the head after multiplying the friction coefficient. 3、 管路弯头磨损、管道摩擦等都要计算在内，实际情况中这些都是不同的，要计算准确也是相当麻烦，所以建议留点空间，保证水泵能打出水。 3. Pipeline elbow wear, pipe friction, etc. should be included in the calculation, these are different in the actual situation, to calculate accurately is also quite troublesome, so it is recommended to leave some space to ensure that the pump can pump water. 4、 如果选择不锈钢排污泵，还要弄清楚水质的酸碱度含颗粒直径等，选择合适的不锈钢材质。一般304材质适合PH4~10之间，超过这个范围建议使用316或者316L不锈钢。 4. If you choose stainless steel sewage pump, but also to clarify the acidity of water containing particle diameter, choose the appropriate stainless steel material. Generally 304 materials are suitable for PH4~10, and 316 or 316L stainless steel is recommended for this range. 5、水泵必须在额定扬程范围内使用，保证电机不过载。 5, the pump must be used in the rated head range to ensure that the motor is not overloaded. |
