That grasping power source (oil pump) and actuators (cylinders, motors) Tongchuan mix hydraulic repair factory, then "even in the middle," that is, from the power source to the execution elapsed between elements of piping and control elements. When "grasping both ends" Tongchuan mix hydraulic repair factory, to analyze whether the fault lies in the pump cylinder and the motor itself. Mechanical noise pilot-type relief issued from the parts of the general strike and due to manufacturing errors, etc. generated friction parts. The noise emitted by the pilot relief valve, sometimes mechanical sound of chattering Tongchuan mix hydraulic repair factory, usually called self-excited vibration and sound. This is the voice of the main valve and pilot valve due to high frequency vibration occurs. Configure its incidence and return oil pipeline, flow, pressure, oil temperature (viscosity) and other factors. Under normal circumstances, the pipe diameter, less flow, high pressure, low oil viscosity, self-excited vibration incidence is high.
