Proportional dosing device of reagents for water systems

Most municipal boiler used «raw» water without any water treatment. For this reason, on the inner walls of pipes is formed a layer of salt deposits, which reduces the technical and economic performance of boilers, their damage. High level of salt deposits occurs on the internal surfaces of water heating heat-exchanger for HTW in the central heat point during their operation without periodic flushing. A method and device (the latter received a patent) of dosing of the reagent is proposed to ensure the cessation of new salt deposits and the gradual elimination of old deposits. The development provides continuous monitoring of pressure in the pipeline, which is dosage, as well as limiting the maximum time between the introduction of regular doses of the reagent.

Keywords: chelating agent, dosing of reagent, water treatment, dosing pump, thermal point, proportional dosing, HTW.

Calculation method for an infra-low frequency drilling fluid pressure gauge

The Calculation method for an infra-low frequency drilling fluid pressure gauge is described. Due to the limited space in a well, geometrical properties of a new measuring device, based on a mechanical occilating system «balance-spiral» were found. The calculation results of a primary pressure gauge are listed. It is shown, that technical properties of a gauge match with the ones in the well, and are correlated with the properties of a wireless electrical transmission channel between the well and the surface.

Keywords: pressure, drilling fluid, balance, spiral, sprocket, pipe spring, transmission channel, actuating system, measuring system. frequency, real-time control, infra-low frequency, method.

Multiple purpose conductometric analyses of technological solutions

Of is observed that wide range conductometers with three independent channels: a channel of measurering electric conductivity; a channel of measuring temperature; a channel of reducing measured values into concentration of binary solutions are more perspective for use as conductometric analyses of binary solutions. Methods of channel calibration of wide range conductometers KS-1M and KL-S are also presented in the paper.

Keywords: conductometer, channel of measuring, calibration.
