Abstract: FIELD: mechanical engineering. SUBSTANCE: heat accumulator has inner reservoir, outer reservoir and heat-insulated chamber located between inner and outer reservoirs. Located in inner reservoir is battery of rectangular (in horizontal projection) flat cells which accumulate latent heat; cells are made of thin metal sheet. Formed between individual cells accumulating latent heat by means of distance grates are intermediate spaces through which cooling liquid flows under working conditions. This cooling liquid acts as heat-transfer agent. Spaces are made in form of clearances at thickness ranging from 1 to 3 mm. Thickness of cells accumulating latent heat ranges from 5 to 8 mm; cells have smooth surface with limited roughness. Battery of cells accumulating latent heat possesses accumulating capacity of at least 400 W.h at temperature of 70 C. Thickness of clearances and thickness of cells are so selected that latent heat accumulator is discharged giving up accumulated heat at rate of 100 Wh/min. Free members of grate are located in such position that turbulent flow is formed at free members of grate at velocity of flow of cooling liquid required for rate of discharge. Members of grate adjacent to latent heat accumulating cells compensate for change in volume of these cells which arises due to conversion of phase of accumulating medium without interfering with formation of turbulence at free members of grate. EFFECT: enhanced efficiency. 3 dwg

Filed: 1995-02-06
Abstract: FIELD: measurement technology. SUBSTANCE: proposed design of transducer of flow rate of liquid and gas makes it possible to increase accuracy and reliability of measurements under vibration and fouling of medium flow. This leads to possibility of its usage under severe industrial conditions. Transducer converts value of flow rate of medium to electric signal which considerably promotes task of automation of accounting process of flow rate of medium with the help of computer. Case isolates sensitive element of transducer from flow of medium which totally excludes interference from fouling and enhanced service life and reliability of transducer. Membranes of which one is central form differential vessel which changes depending on flow velocity and correspondingly on flow rate of medium. Connecting capacitance - voltage to transducer one may generate electric signal proportional to value of flow rate of medium and processing signal by traditional methods one may automate accounting process with the use of computer. If static pressure in pipe-line is high it is possible to strengthen its shell with stiffening ribs and braces. By change of shape of surface, thickness and width of membranes one may change characteristics of transducer (for instance, linear, quadrature, etc) sensitivity, initial static capacitance. One of advantages of transducer is that it does not consume any energy. EFFECT: increased accuracy and reliability of transducer.
