Work, found the problem through sound judgment, as a preventive measure. Cinder machine at work will be issued normal machine operation sounds roadway Grilled mining machine, general electric slag machine noise is relatively small, about 40-60 dB range. When these noise suddenly increases or decreases, or irregularly continues, came from other parts of a new sound, you should pay attention. The main reasons are: ① hydraulic oil filter, inlet pipe blockage or oil viscosity is too high, can cause the pump inlet port of the vacuum is too high, the air infiltration. ② pump, pilot shaft end seal damage or adverse roadway inlet pipe seal Grilled mining machine Which is good, causing air to enter. Tank oil level is too low, so that the pump suction air directly into the pipeline. When working in high noise occurs when the hydraulic pump, you should first check the above site, identify problems in time. (2) excessive wear on the internal components of the hydraulic pump, cylinder and valve plate, piston and plunger holes and other wear parts such as piston fit, the strain Grilled mine roadway maintenance, so that a serious leak in the hydraulic pump, when the hydraulic pump output pressure, flow pulsation will produce a small flow of oil, causing a higher noise. At this angle may be appropriate to increase the pilot system variables agencies to improve the leakage effect within the pump output flow. Hydraulic servo valve spool, controlling the flow of the piston also because local wear, strain roadway Pa Minerals Wikipedia, the piston pulsation during the move, causing fluctuations in the pump output flow and pressure to produce at the pump outlet larger vibration and noise. Response options: then you can wear, serious injury spotting brush element or replacement processing.
