FIELD: machine building. ^ SUBSTANCE: first unit includes independent water supply system for experimental ditches providing visual fixation and demonstration of deposit compression level. Measuring tank is suspended to weight sensor and allows determining the flow rate of the flowing liquid by means of weighing. Mechanical pressure gauge serves for measuring the pressure in the system and pressure transducer provides recording of output data to hard carrier. The second unit includes independent pump station with water pressure main line beginning and ending in feed tank. In the section of water pressure main line there located in series is water supply valve, tank for preparation of liquid with impurities, three in-series connected filters with various permeability, liquid outlet valves, three mechanical pressure gauges for visual observation of pressure drops on filters, and drain valve. On vertical mounting surface of the table there arranged is control system and panel for removing and processing of readings in electronic computing machine. ^ EFFECT: providing the possibility of demonstrating the relationship of water cleaning degree and diameter of pores of filtering elements and capacity of filters and improving measurement accuracy and quality. ^ 2 dwg |
