Abstract

Изобретение относитс  к технической диагностике и обеспечивает повышение точности. В процессе работы турбины на одном и том же режиме работы через заданные интервалы времени измер ютс  температура и давление пара перед соплами турбины, давление пара за турбиной и расход пара. Определ етс  изоэнтропийный перепад и относительный подвод энергии. Определ етс  относительное изменение расхода энергии. В том случае, если полученна  величина больше наперед заданной, турбина подлежит ремонту.This invention relates to technical diagnostics and provides improved accuracy. During turbine operation, the temperature and vapor pressure in front of the turbine nozzles, the vapor pressure behind the turbine and the steam consumption are measured at predetermined time intervals at the same operating mode. Isentropic difference and relative energy supply are determined. The relative change in energy consumption is determined. In the event that the value obtained is greater than the predetermined value, the turbine must be repaired.

Description

Изобретение относитс  к технической диагностике, в частности к способам контрол  технической диагностики судовых турбин .This invention relates to technical diagnostics, in particular, to methods for monitoring technical diagnostics of ship turbines.

Целью изобретени   вл етс  повышение точности.The aim of the invention is to improve the accuracy.

Способ реализуетс  следующим образом .The method is implemented as follows.

В процессе эксплуатации турбины измер ютс  через заданные промежутки времени следующие параметры: температура (tc) и давление (Рс) пара перед соплами турбины , давление (Ра) пара за турбиной и расход (D) пара, который определ етс  объемным методом путем заполнени  мерной емкости за фиксированный период времени . Измерени  производ тс  на одном и том же режиме работы. По замеренным параметрам определ етс  изоэнтропийный теплопериод Н3 f(Pc.tc,P2) и относительный подвод энергииDuring operation of the turbine, the following parameters are measured at predetermined time intervals: temperature (tc) and pressure (Pc) of steam in front of the turbine nozzles, pressure (Pa) of steam behind the turbine and flow rate (D) of steam, which is determined by volumetric method by filling the measuring capacity for a fixed period of time. Measurements are made on the same operating mode. The measured parameters determine the isentropic heat period H3 f (Pc.tc, P2) and the relative energy input

где Н3о и DO - изоэнтропийный теплопере- пад и расход пара на турбину полученные на этапе ходовых испытанийwhere H3o and DO is the isentropic heat transfer and steam consumption per turbine obtained at the stage of sea trials

Последнее позвол ет оценить относительное изменение расхода энергии АК К, - К, 1The latter allows us to estimate the relative change in the energy consumption of the AK K, - K, 1

Индексом i отмечен номер последовательных измеренийThe index i indicates the number of consecutive measurements.

Если полученна  величина ДК больше заданной, турбина подлежит останову и вскрытию дл  ремонтаIf the obtained DK value is greater than the specified one, the turbine must be stopped and opened for repair.
