The Application of Variable Frequency Pump Technology inSprinkler Irrigation Engineering
Introduction
Sprinkler irrigation engineering is an important part of modern agricultural production and an important means for modernization of agricultural irrigation. Variable frequency pump technology is a new technology for irrigation engineering, which can save a lot of energy and water resources, and play an important role in improving efficiency, reducing costs and improving crop quality. With the development of modern agriculture, the application of frequency conversion pump technology in sprinkler irrigation engineering is becoming more and more important, and it has been applied to many irrigation engineering projects.
Background
Sprinkler irrigation technology is one of the most efficient and economical irrigation methods. It can automatically adjust the speed of the sprinkler and the amount of water delivered per unit time, reducing water loss and greatly increasing sprinkler irrigation efficiency and crop yield. Frequency conversion pump technology is a new technology for sprinkler irrigations. It is developed with the rapid development of modern science and technology and the popularization of industrial frequency converter technology. The main feature of variable frequency pump technology is that variable frequency pump and variable frequency speed regulation technology can be used together to realize stepless speed regulation of irrigation motor, and the speed can be adjusted in wide range, so as to achieve the purpose of efficient use of water resources, reduce water consumption and improve the quality of crops.
Advantages
The application of variable frequency pump technology in sprinkler irrigation engineering can improve the efficiency of irrigation and reduce the input of water and electricity resources. The advantages are as follows:
1. The pump speed can be adjusted steplessly, and can be adjusted according to the actual needs of plants and the actual water consumption in different growth stages, so as to improve the utilization efficiency of water resources and reduce energy consumption;
2. By adjusting the pump speed, it can meet the requirements of different irrigated areas and different users, and further improve the utilization efficiency of water resources;
3. The main technical parameters of the inverter regulated frequency pump can be adjusted according to the actual power grid voltage situation, so as to ensure stable operation of the pump system and ensure the peak and voltage quality of the power supply system;
4. The operation cost of frequency conversion pump is much lower than that of conventional pump.
Factors influencing factors
In the application of variable frequency pump technology in sprinkler irrigation engineering, the following factors need to be considered:
1. The quantity and quality of the irrigated area;
2. Water supply and demand, water needs;
3. The actual water intake deviation from the plan should be considered in advance;
4. The selection of the motor should take into account the power and torque requirements;
5. The environmental temperature and humidity of different places should also be considered;
6. The requirements for working accuracy, response speed and noise of the system should be taken into account.
Conclusion
Sprinkler irrigation engineering is an important part of modern agricultural production and an important means for modernization of agricultural irrigation. Variable frequency pump technology has many advantages, such as energy saving, water saving, improving efficiency, reducing cost and improving crop quality, which have played an important role in modern agricultural production. However, in the application of variable frequency pump technology in sprinkler irrigation engineering, some factors need to be considered in order to achieve the best application results.
