Drainage Pump Selection Skills
Drainage pumps are widely used in agricultural production, urban infrastructure construction and other fields. Drainage pumps are mainly used for drainage, water supply and water circulation. When purchasing drainage pumps, the most important thing is to choose the right type of drainage pump, which can not only save money, but also increase efficiency. Here, the following introduction will be given on how to purchase a drainage pump.
First of all, it is necessary to understand the flow rate and lift height requirements of the drainage pump. The calculated flow rate is the amount of water discharged by the pump per unit time. The pumps lift height should refer to the maximum static lift. In general, the static lift can be calculated by the formula: HL = H2-H1, where H2 is the water outlet height and H1 is the water inlet height. Knowing the flow rate and lift height requirements of the drainage pump can help to calculate the power requirements of the drainage pump.
Secondly, it is important to choose the right power for the drainage pump. Generally speaking, the motor power of the drainage pump is determined by the actual task force. Too low motor power will not meet the requirements of the drainage pump, while too high motor power will increase the cost of the drainage pump. Therefore, it is important to choose an appropriate motor power for the drainage pump.
Thirdly, it is important to pay attention to the materials of the drainage pump. Generally speaking, the materials of the drainage pump are divided into cast iron and stainless steel. Cast iron materials are more common on the market and are cheaper. Stainless steel materials are more expensive and more corrosive-resistant, but the overall performance is better than that of cast iron materials. It is important to choose the right material according to the actual application environment of the drainage pump.
Fourthly, it is important to pay attention to the protection level of the drainage pump. Generally speaking, the protection of drainage pumps mainly includes IPX4 and IPX8, which refer to the ingress protection rating of the internal parts of the drainage pump. IPX4 is the minimum protection level and can only be used in dry and non-corrosive places, while IPX8 requires the highest protection level and can be used in wet and corrosive places. Therefore, it is important to choose the right protection level according to the actual application environment of the drainage pump.
After understanding the above points, it is also important to pay attention to the installation space of the drainage pump during the selection process. Generally speaking, the installation space of the drainage pump should be based on the actual situation. Usually, the installation space of the drainage pump should be selected according to the size and layout requirements of the drainage pump. In addition, it is also necessary to ensure that there is enough space for the motor and other accessories of the drainage pump.
In summary, when purchasing a drainage pump, it is important to first understand the flow rate and lift height requirements of the drainage pump, choose the right power for the drainage pump, pay attention to the materials and protection level of the drainage pump, and ensure enough installation space for the drainage pump. By following the above tips, you can purchase the right type of drainage pump for your specific application.
