When the hydraulic oil contains air bubbles, the bubbles are sucked oil with a cylinder bore of a hydraulic compactor repair phone, plug in the cylinder bore oppression hydraulic oil into the cylinder with flow surface of the drain window, under high pressure, the oil The bubble will burst suddenly crowded, almost the same size of the bubble is the high-pressure concentrated after sudden collapse, causing another ultra-high-pitched noise hydraulic roller when a strong gas explosion, burst the bubble generated by service Price, emits a 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 quote, 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. In the form of leaks as leakage flow can be divided into leakage and external leakage. Mainly refers to the external leakage of hydraulic oil leaking into the environment from the system, resulting in the hydraulic lines of the hydraulic system, hydraulic valves, hydraulic cylinders and hydraulic pumps external (hydraulic motor); internal leakage is due to the pressure difference between the high and low side presence and a seal failure and other reasons, the hydraulic oil flow from inside the system low pressure side of the high pressure side, such as hydraulic transmission fluid leaking from the high pressure chamber to the low pressure chamber; the pressure valve from the oil return passage to passage of leakage. The main form there is a gap leak leak leak porous, adhesion leakage and leakage power roller hydraulic repair phone | Xi'an Chengtong hydraulic service | Weinan roller hydraulic service from Xi'an Chengtong hydraulic maintenance Limited.
