The invention discloses a piston type filling industrial pump hydraulic system. The piston type filling industrial pump hydraulic system comprises a power device and a pumping device; the power deviceis formed by connecting at least two power units in parallel, each power unit comprises an oil tank and a motor oil pump set, each motor oil pump set comprises a main oil pump and a flow dividing oilpump, every two power units are paired and oppositely arranged, and the multiple pairs of power units are tightly attached and arranged side by side; the pumping device is connected with a motor oilpump set through a pipeline and comprises a main valve set, a distribution valve set and an S-pipe pump valve, the S-pipe pump valve is used for pumping materials, the main valve set receives power from a main oil pump and provides the power for the S-pipe pump valve, the distribution valve set receives power of the flow dividing oil pump so as to control reversing of the S-pipe pump valve, and the distribution valve set is further connected with the power device through the pipeline. The power device is compact in layout, occupied space is saved, and the pumping device can effectively meet the large-volume and high-pressure conveying requirements.
Description
technical field [0001] The invention relates to the field of material conveying, in particular to a piston-type filling industrial pump hydraulic system. Background technique [0002] At present, with the vigorous strengthening of environmental protection by the state, the production requirements for existing coal mines, metal and non-metal mines and other enterprises are becoming more and more stringent. Most enterprises use mine tailings, gravel, fly ash, industrial slag and other solid waste to make paste slurry that does not need to be dehydrated, and it is continuously transported to the underground goaf for filling by filling industrial pumps. It can increase the rate of resource exploitation and reduce land occupation and environmental pollution. [0003] With the wide application of filling industrial pumps, according to the different characteristics of tailings produced by different mines, the requirements for the pumping volume and delivery distance of existing fi...
