Intelligent stepless proportioning implementation method

Abstract

The invention provides an intelligent stepless proportioning implementation method. High and low capacitance pressure sensors are installed in a pulping barrel in a grouting circuit, slurry and watersupply valves are installed on raw slurry and clear water inlet pipes, a micro controller is used to obtain a measured proportioning density and volume. A main control program for the real-time monitoring of a proportioning density is used, and with a program (time-based interval volumetric injection method), the obtainment of any volume of raw slurry or clear water with an allowable error range is achieved. The shortening of a water injection time process is also used to overcome the problem of the increase of a proportioning in a time slice method. The problems of unstable quality, a long time of technician training, high cost, easy falsification and the damage to project quality of traditional artificial proportioning are solved, tests prove that a measured slurry density is in a rangeof + / -0.03 g / cm3 of a set slurry density with the proportioning of the invention, setting parameters can be followed well, the method has strong anti-disturbance performance and can be well adapted toon-site proportioning requirements. Under the constraints of many factors of a proportioning and grouting system, the precise program control of the stepless proportioning is realized. The method canbe used in intelligent grouting engineering of hydropower stations.

Description

(1) Technical field: [0001] The invention provides a method for realizing intelligent stepless grouting, and relates to a computer programming control method for a grouting unit machine system. It is used for engineering measurement and quality control in hydropower station grouting engineering. It belongs to capacity and flow measurement (G01F). (two) background technology: [0002] The slurry mixing process is the process of reconfiguring the raw cement slurry with a density of 1.82g / cc and water into a cement slurry with a certain density. In the traditional pulp mixing process, the pulping station first sends the raw pulp with a concentration of 1.82g / cc to the storage tank of the grouting face, and then the on-site workers put a certain amount of raw pulp and a certain amount of raw pulp from the storage tank based on personal experience. Put a certain amount of clear water into the grout mixing tank to make grout that meets the density required for grouting. It can ...
