  • 977HP sealing oil differential pressure valve

    977HP sealing oil differential pressure valve

    The 977HP differential pressure regulating valve is used in the sealing oil system of the generator set by comparing the sum of hydrogen pressure and spring pressure with the oil pressure. When there is a pressure difference, the valve stem moves up and down, which affects the opening of the valve port and makes The flow and pressure at the outlet of the differential pressure valve change accordingly, and the pressure balance is finally achieved. At this time, the pressure difference ΔP between hydrogen pressure and oil pressure is relatively constant, and the pressure difference value ΔP can be adjusted by adjusting the spring. The differential pressure adjustment range of this valve is 0.4~1.4bar.
  • NXQ series EH oil system accumulator Rubber bladder

    NXQ series EH oil system accumulator Rubber bladder

    NXQ series bladders are used together with this series of accumulators.

    After the accumulator is put into use, check the air pressure of the air bag once a week, to once a month, and then once every six months. Regular inspection can detect leaks and repair them in time to maintain the best use of the accumulator.
  • YAV-II accumulator Rubber bladder gas charging valve

    YAV-II accumulator Rubber bladder gas charging valve

    YAV-II type charging valve is a one-way valve for charging the accumulator with nitrogen. The charging valve charges the accumulator with the aid of a charging tool. After the inflation is completed, it can be closed by itself after removing the inflation tool. This filling valve can also be used for filling of non-corrosive gases. This type of inflatable valve has the characteristics of small volume, high pressure bearing and good self-sealing performance.
  • Steam turbine tilting pad thrust bearing

    Steam turbine tilting pad thrust bearing

    Tilting pad thrust bearing is also called Mitchell type radial bearing. The bearing pad is composed of several bearing pad arc segments that can rotate around its fulcrum. The gap between each bearing pad arc segment serves as the oil inlet of the bearing pad. When the journal rotates, Each tile forms an oil wedge. This kind of bearing has good self-centering performance and will not cause instability. The pad can be tilted freely on the support point, and the position can be adjusted freely to adapt to the changes of dynamic conditions such as rotational speed and bearing load. The oil film force of each pad passes through the center of the journal, and it does not cause the shaft to slide. Therefore, it has high braking performance, can effectively avoid oil film self-excited oscillation and gap oscillation, and has a good limiting effect on unbalanced oscillation. The bearing capacity of a tilting pad radial bearing is the vector sum of the bearing capacities of each pad. Therefore, it has a lower bearing capacity than a single oil wedge hydrodynamic radial bearing, but has high rotation accuracy and good stability, and is widely used in high-speed and light-load machinery, such as steam turbines and grinders.
  • Sealing Ring of Generator Hydrogen Cooling System

    Sealing Ring of Generator Hydrogen Cooling System

    Sealing ring is an important part of hydrogen cooled generator. At present, double flow ring type sealing ring are generally used in China.

    In order to prevent the leakage of high-pressure hydrogen in the hydrogen cooled generator along the gap between the casing at both ends of the generator and the rotor, a sealing ring device is installed at both ends of the generator to seal the hydrogen leakage by the flowing high-pressure oil.
