Abstract

The invention provides a multi-pump multi-frequency-conversion emulsion pump station system for mining. The multi-pump multi-frequency-conversion emulsion pump station system for mining comprises 400 KW frequency conversion control cabinet, a 110KW frequency conversion control cabinet, four 400 L / min emulsion pumps and a 80 L / min emulsion pump. One end of the 400 KW frequency conversion control cabinet is connected with the 110 KW frequency conversion control cabinet, and the other end of the 400 KW frequency conversion control cabinet is connected with the four 400 L / min emulsion pumps. The 110KW frequency conversion control cabinet is further connected with the 80 L / min emulsion pump. The multi-pump multi-frequency-conversion emulsion pump station for mining adopts the multi-pump multi-frequency-conversion drive manner, the four emulsion pumps with the rated flow of 400 L / min and the emulsion pump with the rated flow of 80 L / min are arranged, each pump can achieve frequency conversion speed control and electronic control loading and unloading, the emulsion supply flow adjustment range can reach 0-1680L / min, and the highest adjustment precision can reach 1.6 L / min; on the basis of the multi-pump multi-frequency-conversion emulsion pump station system for mining, a rated emulsion supply control method is provided. According to the rated emulsion supply control method, through PLC programming in the control cabinet, the multiple pumps are controlled to operate at the industrial frequency, multi-frequency-conversion speed adjustment is controlled, accurate and quantitative control over high-pressure emulsion flow is achieved, and a reliable underlying control basis is provided for further intelligent emulsion supply.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to a mine-used multi-pump and multi-frequency conversion emulsion pumping station system and a quantitative liquid supply control method. Background technique [0002] The emulsion pump station system, the hydraulic support system and the corresponding pipelines together constitute the hydraulic system of the working face, which provides guarantee for the production advancement of the working face. Among them, the emulsion pump station system is the hydraulic power source, and its main function is to provide qualified and sufficient high-pressure power emulsion for the hydraulic support of the working face. [0003] In the existing emulsion pump station drive technology, most of them use multiple emulsion pumps to supply liquid in parallel, each pump is equipped with an electromagnetic unloading valve, and the multi-stage adjustment of the liquid supply flow is...
