Selection and application of agricultural irrigation pumps
In agricultural irrigation, the selection and application of water pumps are crucial, which is directly related to the growth of crops and the efficiency of agricultural production. The following are some suggestions for the selection and application of agricultural irrigation water pumps:
1. Selection of water pump types
The types of water pumps commonly used in agricultural irrigation are mainly centrifugal pumps, axial flow pumps, mixed flow pumps and submersible pumps.
Centrifugal pumps: The head is high, but the water output is relatively moderate. It is suitable for irrigation scenes that require a large head, such as mountainous areas and well irrigation areas.
Axial flow pumps: The water output is large, but the head is low. It is suitable for use in plain areas or rivers and channels with low head, and can quickly provide a large amount of irrigation water.
Mixed flow pumps: Its water output and head are between centrifugal pumps and axial flow pumps, and it is suitable for irrigation needs in plains and hilly areas.
Submersible pumps: Mainly used to pump water from deep wells, suitable for plain areas or plateau mountainous areas where surface water is scarce, with the advantages of reliable operation and easy installation.
2. Consideration of performance parameters
When selecting a water pump, you need to pay attention to its performance parameters, such as flow, head, power, etc. These parameters should be determined according to actual irrigation needs and irrigation conditions. For example, areas with large irrigation areas and high crop water demand should choose pumps with larger flow rates; while areas with low irrigation water sources or long-distance transportation require pumps with higher lifts.
3. Balance between economy and practicality
When choosing a water pump, you also need to consider its economy and practicality. On the one hand, you should choose a pump with high cost performance to ensure that it meets the irrigation needs while reducing production costs; on the other hand, you should consider the durability and maintainability of the pump and choose a pump with reliable quality and easy maintenance to reduce the cost of later maintenance and replacement.
4. Application precautions
When using agricultural irrigation pumps, you need to pay attention to the following points:
Regularly check and maintain the pump to ensure its normal operation;
Reasonably arrange irrigation time and irrigation volume to avoid wasting water resources;
Pay attention to the installation and use environment of the pump to avoid equipment damage caused by use under harsh conditions;
Comply with relevant safety regulations and operating procedures to ensure the safety of personnel and equipment.
