  • System and method and process for detecting performance degradation of control valve
    Control valves in turbo compressor anti-surge and steam turbine applications often remain in one position for a longer period of time. When the valve needs to move, the response of the valve may be severely degraded, or the valve may not even respond at all. This may be due to the accumulation of foreign matter between the moving and fixed elements of the valve, which can lead to increased friction or complete seizure of the valve. In some cases, when operating in a constant position, the actuator of the valve may malfunction.

  • Manufacturing method for controlling hydraulic system for smooth landing of open bridge to bridge support
    The invention relates to the field of bridge hydraulic transmission systems, in particular to a hydraulic system for controlling the opening of a bridge to smoothly fall to a bridge support. The vertical turning type opening bridge is a kind of opening bridge which can be opened and closed on the elevation by the movable bridge span above the channel. The vertical swing opening bridge usually uses a hydraulic oil cylinder system to drive the movable bridge span to rotate around a main shaft, thereby achieving the bridge span opening and closing action. Due to the long stroke, large volume and heavy weight of the vertical opening bridge cylinder, once installed in place ...
  • Hydraulic oil filtering mechanism, hydraulic device and high-voltage circuit breaker
    The invention relates to oil, in particular to a hydraulic oil filtering mechanism, a hydraulic device and a high-voltage circuit breaker.

  • Manufacturing method of portable pressure release valve detection table
    The invention relates to the verification of a pressure release valve for a transformer, and in particular to a portable pressure release valve detection station. A pressure relief valve is a pressure protection device for a transformer. When a transformer internal failure occurs, a large amount of gas is generated by oil decomposition. Because the transformer is basically closed, the connecting pipe connecting the oil pillow is thin, and the small connecting pipe alone cannot effectively and quickly reduce the pressure, causing the pressure in the fuel tank to rise sharply. Failure to provide a pressure relief valve can cause ...
