Pressure regulating method and system for concrete pumping equipment and concrete pumping equipment

Abstract

The invention discloses a pressure regulating method and system for a concrete pumping apparatus, and the concrete pumping apparatus, wherein the system comprises a constant pressure pump, a pressure sensor for acquiring a pumping pressure value and a pumping pressure change rate, a pressure regulating valve connected with the constant pressure pump and used for regulating distributed pressure output by the constant pressure pump, a controller connected between the pressure sensor and the pressure regulating valve and used for receiving the pumping pressure value and the pumping pressure change rate acquired by the pressure sensor and controlling the regulating valve opening of the pressure regulating valve according to the pumping pressure value and the pumping pressure change rate, and an oscillating oil cylinder connected with the constant pressure pump and used for obtaining the distributed pressure output by the constant pressure pump and pressure oil from an accumulator so as toobtain reversing pressure to push a distribution valve. According to the system disclosed by the invention, longitudinal impact on an entire vehicle is greatly reduced during distribution reversing by smartly regulating the distributed pressure output by the constant pressure pump, so that the service life of a hardware device is prolonged, and simultaneously, well energy saving is achieved.

Description

technical field [0001] The invention relates to the field of concrete machinery, in particular to a pressure regulating method and system for concrete pumping equipment and the concrete pumping equipment. Background technique [0002] With the rapid development of my country's infrastructure, the development and growth of the concrete machinery industry in various places is also unprecedented. How to reduce the vibration during the pumping process, and how to improve the service life of the device and the pumping efficiency are directly related to the economic benefits of the pump truck users. [0003] At present, the existing technology often uses the maximum fixed distribution pressure value to control the distribution reversing. At this time, the distribution reversing will produce a longitudinal impact on the vehicle, and the impact will be kept at the maximum, which increases the mechanical parts of the system. Wear and tear, resulting in a certain waste of energy. ...
