When the hydraulic oil contains air bubbles, the bubbles are sucked oil with a cylinder bore, the piston in the cylinder bore oppression of hydraulic oil into the cylinder with flow surface of the drain window, under high pressure, the oil bubbles will suddenly crowded rupture, almost the same size of the bubble is concentrated and then sudden high voltage collapse, causing a powerful gas explosion roller hydraulic repair price, another ultra-pitched noise generated when the bubble burst, it will issue a loud, shrill whistle. This is followed by the shrill noise of the pump pressure varies. When the output pressure of the pump to the highest, that the higher the decibel, when the pressure drop roller hydraulic pump repair phone, this noise along with the weak. When the pump suction noise generated by a small amount of air sounds like a rattling sound, a bit like the sound of bearing damage. When the pressure is raised to a high pressure pump, it produces a very strange thumping noise burst. System Flushing assembled and put into use the new hydraulic system is absolutely necessary roller hydraulic maintenance Which is good, have chances to give up any cleaning will bring fatal damage to the equipment. After rigorous washing, you can reduce and prevent system commissioning and early operation of the fault, to shorten the debug cycle system and reduce unnecessary losses. However, the pollution control system is an ongoing process, and is not guaranteed, even during operation of the system regularly to detect the oil state, and control of contaminants in the system allows it to ensure cleanliness within range.
