Embodiment Construction
[0032] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0033] The target pumping speed in this application refers to the average pumping speed within one pumping cycle, and the stable pumping speed refers to the stable speed in a uniform pumping state. In general, the steady rate of pumping is higher than the average pumping rate.
[0034] Such as image 3 As shown, according to the embodiment of the present invention, the pumping system includes a delivery cylinder, a main oil pump for driving the delivery cylinder, and an engine for driving the main oil pump. The pumping speed control method includes the following steps: S10, according to the pumping speed stage where the target pumping speed is, determine the start-up acceleration of the delivery cy...
