Abstract

The invention provides a pressure control valve group for pumping device debugging; the pressure control valve group comprises multiple flow control valves and an overflow valve which are connected between a water inlet pipe and a water outlet pipe; the multiple flow control valves and the overflow valve are connected in parallel, and the multiple flow control valves and the overflow valve are alldriven by a stepping motor; and the pressure control valve group also comprises a pressure control module used for controlling movement of the stepping motor. Through-flow sectional areas of the flowcontrol valves and the overflow valve are controlled by arranging the pressure control module to control the movement of the stepping motor, the required simulated load pressure can be adjusted automatically, so that the pumping debugging of the pumping device is efficient, safe and accurate.

Description

technical field [0001] The invention relates to a hydraulic debugging technology, in particular to a pressure control valve group for pumping equipment, an automatic debugging system, pumping equipment and an automatic debugging method. Background technique [0002] At present, the pumping hydraulic system adopted by most manufacturers of concrete pumping equipment (such as concrete pump trucks, vehicle pumps, trailer pumps, cement mortar pumps, etc.) is a water valve with a complete mechanical ball valve structure. In the process of pump water debugging, the opening of the ball valve is manually adjusted to simulate the concrete medium as the output load of the pumping unit, and at the same time adjust the mechanical constant power device of the main pump or the displacement value of the main pump to achieve the debugging of the constant power of the main pump. Purpose. Among them, due to the poor linearity of the adjustment of the water valve of the mechanical ball valve ...
