Abstract: Изобретение относится к области гидравлики и предназначены для использования при разработке клапанов (РК) и гидравлической арматуры различного назначения, а также при исследовании гидравлических характеристик различных местных сопротивлений. Способ определения начала кавитации в регулирующем клапане заключается в том, что замеряются давления среды на входе и выходе клапана при фиксированном положении затвора и изменении перепада давлений на нем. Режимы проводятся при постоянных значениях давления среды на входе РК с определением вибрационных характеристик клапана в функции перепада давлений на нем при гидродинамическом и кавитационном режимах. По координате отклонения последних друг от друга фиксируется соответствующий критический перепад давлений на клапане. По критическому перепаду и значениям давлений на входе РК и насыщенных паров жидкости при температуре потока определяется фактическое значение коэффициента кавитации. Второй вариант определения фактического значения коэффициента кавитации повторяет все этапы первого способа, за исключением того, что вместо вибрационных характеристик клапана берется уровень акустического шума клапана. Указанные способы просты для клапанов различных условных проходов и конструктивного исполнения при работе их в любом диапазоне изменения чисел Рейнольдса с целью разработки бескавитационных РК. 2 с.п. ф-лы, 3 ил.

Abstract: FIELD: high- temperature spraying using acetylene substitutes on hydrogen-oxygen mixture generated from water by means of electrolyzers. SUBSTANCE: proposed method is based on use of water steam as combustion product due to use of ecologically pure hydrogen-oxygen mixture as fuel and carrier gases and avoidance of back impact inside burner when hydrogen- oxygen mixture is used as carrier gas due to equalization of rate of escape of gases from powder channel and orifices of tip. Hydrogen-oxygen mixture generated by electrolysis from water is used as carrier gas and fuel gas; control of flame is effected by additional feed of carbon- containing gases, for example butane-propane to hydrogen-oxygen mixture. Burner proposed for realization of this method is provided with attachment on which tip is secured, bush with channel mounted in tip coaxially relative to central nozzle and cock for control of flow rate of carrier gas. Channel in bush is made in form of cylindrical orifice with chamfer which changes to tapering part having cylindrical section. Ratio of sizes of channel and outlet holes of tip of nozzle end-piece protects burner against back impact in channel. Use of hydrogen-oxygen mixture instead of oxygen or air as carrier gas considerably increases heat capacity of burner flame, thus excluding contamination of surrounding medium. EFFECT: reduction of toxic emissions; enhanced ecological safety. 3 cl, 3 dwg
