Embodiment 1

[0022] This embodiment includes a motor 1, an oil pump 2, an electric proportional flow regulating valve 3, a motor 4 and an accelerator pump 5, which are connected in sequence. The oil pump 2 is connected with the motor 1 through a coupling 16, and the accelerator pump 5 is connected to the motor 4 Through the coupling II 7 connection, the coupling II 7 is provided with a speed measuring device 8, the motor 1 drives the oil in the oil pump 2 to flow through the electric proportional flow regulating valve 3 and is sent to the motor 4, and the motor 4 is used to drive the accelerator pump 5 , by adjusting the electric proportional flow control valve 3 to change the oil supply of the motor 4 to change the speed of the accelerator pump 5 .

[0023] The speed-regulating control system for the delivery of accelerators also includes a controller 8 for controlling operations.

[0024] The accelerator pump 5 is a screw pump, and the relative movement of the stator and the rotor realiz...

Embodiment 2

[0030] The difference between this embodiment and Embodiment 1 is that the accelerator pump 5 is a peristaltic pump, which realizes fluid output by squeezing the hose through a cam. The speed measuring device 8 uses the photoelectric code disc speed measurement method, and is composed of a light source and a photoelectric code disc. The same as in Example 1.

Abstract

The invention discloses an accelerator conveying and speed regulating control system. The system comprises an electrical machine, an oil pump, an electric proportional flow regulating valve, a motor and an accelerator pump which are connected in sequence, wherein the oil pump is connected with the electrical machine through a coupler I, the accelerator pump is connected with the motor through a coupler II, a speed measuring device is arranged on the coupler II, the electrical machine drives oil in the oil pump to flow into the motor through the electric proportional flow regulating valve, themotor is used for driving the accelerator pump, and the oil supply amount of the motor is changed by adjusting the electric proportional flow regulating valve so as to change the rotating speed of theaccelerator pump. According to the control system, data are collected through testing, curve fitting is carried out, the difference between the different accelerator pumps and adjusting flow proportional valves is considered, and the rapid and accurate speed regulation of an accelerator system is realized through data calibration during debugging. The method is simple, rapid, free of oscillation,rapid and stable, and high in precision.

Description

technical field [0001] The invention relates to a speed-regulating control system and a calibration method for the delivery of an accelerator. Background technique [0002] The prior art generally adopts the PID technology to realize the speed regulation of the quick-setting agent conveying device, which has the defects of easy oscillation, slow response of speed regulation and poor precision. [0003] CN 201510847120 discloses a speed-adjusting method for an accelerator of a concrete shotcrete truck. The accelerator pump is driven by a hydraulic motor, and the method includes the following steps: obtaining the current rotational speed n of the hydraulic motor of the accelerator pump and the current flow rate of the accelerator Qs= f(n); obtain the current concrete flow rate Qt, and calculate the current accelerator ratio as M=Qs / Qt; obtain the target accelerator ratio M0, and calculate the difference between the target accelerator ratio and the current accelerator ratio Va...
