Problems solved by technology
[0004] However, if the actual displacement currently required cannot be equal to the displacement obtained through the stator eccentricity, that is to say, the displacement obtained by changing the stator eccentricity cannot be equal to the actual displacement. Therefore, at present, only by changing the stator eccentricity Adjusting the displacement can only achieve step-by-step adjustment of the displacement, resulting in low accuracy of displacement adjustment

The invention provides a controlling method and device for a radial plunger pump and an electronic terminal, and relates to the technical field of application of hydraulic devices. Corresponding standard plunger modes can be determined based on required actual flow, so that accurate output of discharge capacity corresponding to the actual flow can be realized according to the standard plunger modes; and relative to a conventional way of regulating the discharge capacity through change of stator eccentricity, the method disclosed by the invention has the advantages that stepless regulation of the discharge capacity is realized and the technical problem of lower regulation accuracy of the discharge capacity can be alleviated. The method comprises the following steps: calculating the required actual flow when a gear command for operating the radial plunger pump is received; determining the standard plunger modes matched with the actual flow, wherein the standard plunger modes comprise rotation angle ranges, relative to stators, of rotors marked by an angle sensor; and controlling an electromagnetic proportion valve and a switch valve according to the rotation angle ranges in the standard plunger modes.
Description
technical field [0001] The present application relates to the technical field of application of hydraulic devices, in particular to a control method, device and electronic terminal of a radial piston pump. Background technique [0002] At present, plunger pumps are generally divided into single plunger pumps, horizontal plunger pumps, axial plunger pumps and radial plunger pumps. The plunger pump is an energy conversion device that can convert the mechanical energy output by the prime mover into Pressure energy, hydraulic oil that provides a certain pressure and flow for the hydraulic system, is an important power component in the hydraulic system. [0003] When working, the plunger pump mainly relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to realize oil suction and discharge. Among them, the radial plunger pump plunger and cylinder are perpendicular to the transmission axis, and are mainly composed of...
