Start control method for hydraulic pump of excavator
The invention relates to the field of engineering machinery, in particular to a start control method for a hydraulic pump of an excavator. The start control method for the hydraulic pump of the excavator comprises the steps that when the hydraulic pump idles, the main displacement of the hydraulic pump is controlled to a first preset value; and when the hydraulic pump starts to work, the main displacement of the hydraulic pump is directly increased to a second preset value from the first preset value according to a first preset rate, and the first preset value and the first preset rate are both larger than 0. The start control method for the hydraulic pump of the excavator can improve the stability of the hydraulic pump during working.
本发明涉及工程机械领域，具体而言，涉及一种挖掘机的液压泵的启动控制方法；该挖掘机的液压泵的启动控制方法包括在液压泵空载时，控制液压泵的主排量为第一预设值；在液压泵开始工作时，控制液压泵的主排量直接从第一预设值按照第一预设速率增加到第二预设值；其中，第一预设值和第一预设速率均大于0。本发明的挖掘机的液压泵的启动控制方法能够改善液压泵工作时的稳定性问题。
