Introduction
Pumps are widely used in agriculture. In many cases, water is used for irrigation, water supply, water processing, and drainage. In order to reduce the energy consumption of agricultural water pumps and save energy, energy-saving transformation of pumps is an inevitable choice.
Energy saving transformation of agricultural pumps
1.Reasonable selection of pumps
When selecting a water pump, the most important thing is to consider its efficiency. The same model of pump has different performance parameters in different manufacturers or even in the same model of different manufacturers. Therefore, we should choose the most suitable pump according to the parameters and characteristics of the pump, and strive to choose the pump with the highest cost performance.
2.Optimize operating parameters
Properly adjust the relevant parameters of the pump, such as outlet pressure, outlet flow rate, pump speed, and impeller size, to ensure reasonable matching of the pump.
3.Strengthen maintenance
Lack of maintenance or neglect of regular maintenance of water pumps will lead to the degradation of its performance and the increase of energy consumption. Therefore, experts suggest that it should be replaced or maintained according to its service life.
4.Reduce the water supply head
Generally, the height of agricultural water is too high and the inner resistance is large. Therefore, quantifying the water head of the pump can reduce the energy consumption of the pump.
5.Reasonably using split gear
In order to reduce start-up power, the agricultural water pump can be reduced from the rated speed to low speed when starting and from low speed to rated speed when stop. This can reduce the energy consumption of the pump and prolong its service life.
6.Pay attention to matching
When matching the water pump, the head, power and speed of the pump should be adapted to the characteristics of the motor. The size of the pump should be matched with the flow rate and the motor power should not be too large, so as to reduce the minimum flow rate and prolong the service life of the water pump.
7.Improve the efficiency of the motor
Adoption of high-efficiency motors can not only reduce the start-up current, but also can reduce the power factor and improve the efficiency, thus effectively reducing the energy consumption of the water pump.
Conclusion
The energy-saving transformation of agricultural water pumps can not only reduce the energy consumption of farmer pumps, but also reduce the operating cost and protect the ecological environment. Reasonable selection and optimized using of agricultural water pumps require the joint efforts of experts, manufacturers, agricultural machineries, and farmers.
