There is a healthy state. The discrepancy between the relations obtained from the initial ones more than does not indicate a malfunction of the hydraulic lift unit. Moreover, if the operating pressure ratio is less than the initial pressure, the damage is classified as depressurization of the device, chipping of babbit in the area of the chambers 6 of the hydraulic assembly, etc., and if more, this indicates wear of the anti-friction material, tightening with the babbit chambers 6 of the hydraulic lift, sanding the oil feed hole (not shown). At that, further operation of the device (bearing) is stopped, inspection and repair of the hydraulic lift device is performed.

Claims (2)

1. The method of controlling the compliance with the set parameters of the hydraulic turbine rotor lifting device of the steam turbine by measuring the pressure of lubricant in the supply line to the hydrostatic stations of the radial bearing 0 five 0 five 406 In a dynamic mode, sweeping at a fixed rotor speed, then determining the control parameter and comparing it with the control parameter, characterized in that, in order to increase the reliability and accuracy of the fault control, the pressure of the lubricant in the flow line in the hydrostatic dynamic lubrication mode at turbine start-up after montage or repair, determine the initial ratio of this pressure to pressure h of the hydrodynamic lubrication regime, which is taken as a parameter Trol in the absence of malfunctions, and during operation, the indicated lubricant pressure is measured at the same fixed values of the rotor rotation frequency, the pressure ratio is determined, the pressure is compared to the initial one, and the presence of a malfunction is determined by the magnitude of the mismatch. 2. The method according to claim 1, about tl and h a torn, and with the fact that if the value of the operating ratio of the pressure deviates by more than 10% from the initial value, the device is subject to revision.
