Due to various reasons, the air is inhaled in the oil, or when the oil pressure is below atmospheric pressure, the partial air dissolved in the oil will precipitate the formation of bubbles, and these air bubbles are large in the low pressure area, when the oil When the liquid flows to the high pressure zone, it is compressed, the volume suddenly becomes small or the bubble is disappeared; Change the phenomenon. Sudden changes in bubble volume generate noise, but since this process occurs in an instant, it will cause local hydraulic shock to generate vibration. The guiding valve port of the pilot-type overflow valve and the main valve, the fluid flow rate and the pressure are changed, and there is easy to have noise and vibration.
