Generally, when the circulating oil pressure is lubricated, the inlet oil temperature should be kept at about 35℃; Japanese HD bolt equipment harmonic FHA-40C-50-E250-L two axis radial displacement deviation is too large, with *** table re-alignment adjustment, to reach the standard allowed range; For shaft bending and shaft journal elliptic out-of-tolerance should be carefully trimmed, serious, to replace parts. Due to the parts loose imbalance, should be re-fixed parts (check the method, so that the rotor rotation at low speed, then the internal sound of knocking or rolling sound,

Japanese HD bolt equipment harmonic FHA-40C-50-E250-L can be found with a listener). The reason belongs to the manufacturer, should do the unbalance test again and take corresponding measures. When the rotating shaft and shaft seal ring and other oil retaining device collide, the oil retaining ring device should be readjusted. Japanese HD bolt equipment harmonic FHA-40C-50-E250-L foundation and equipment base bolt fastening force is not enough, the use of torque wrench for fastening. The resonance phenomenon of the unit is solved by increasing the weight of the foundation.
