In order to improve the mechanical efficiency of the fertilizer application pump in water and fertilizer integration machine, an equal-section double-acting plunger pump was designed. The mechanical efficiency of the new plunger pump was tested under different working conditions. The motor speed, plunger stroke, irrigation main line pressure and equal-section double-acting plunger pump were quantitatively analyzed. The test results showed that the mechanical efficiency increased from 2.42% to 8.11% when the motor speed was set to 40% and the main irrigation pipe pressure was adjusted from 0.05 MPa to 0.30 MPa. When the motor speed was set to 100%, the mechanical efficiency increased from 5.92% to 21.07%. When the ratio of the motor speed to the plunger stroke was 100%, the mechanical efficiency increased from 8.11% to 21.07%, which was 49.5% higher than the 10.44% of traditional agricultural three-cylinder plunger pump. Compared with the traditional plunger pump, the volume loss of the new plunger pump is reduced by up to 3%. The new plunger pump can precisely control the fertilization flow rate by adjusting the motor speed, plunger stroke, and irrigation main pipeline pressure. It has the advantages of high mechanical efficiency, small volume loss, and easy operation, making it suitable for water and fertilizer integration and precise fertilization.

為提升水肥一體化機施肥泵的機械效率，設計了一種等截面雙作用柱塞泵，並開展了新式柱塞泵在不同工況下機械效率的試驗，定量化分析電機轉速、柱塞行程及灌溉主管道壓力與等截面雙作用柱塞泵機械效率的回應關係。試驗結果表明：灌溉主管道壓力由0.05 MPa調節至0.30 MPa，電機轉速40%時，機械效率從2.42%提升至8.11%；電機轉速100%時，機械效率從5.92%提升至21.07%；電機轉速與柱塞行程比例均為100%時，機械效率從8.11%提升至21.07%，相較於傳統農用三缸柱塞泵的10.44%，機械效率提升49.5%；新式柱塞泵容積損失相比傳統柱塞泵最大減少3%。新式柱塞泵可通過調節電機轉速、柱塞行程及灌溉主管道壓力實現精准控制施肥流量的效果，具有機械效率高、容積損失小，操作方便等優勢，適用於水肥一體化精准施肥。
