Hydraulic motor noise
(1) Couplings, gears, etc. of the output shaft of the hydraulic motor are installed with different concentricity. When operating, there is a great deal of difficulty. The concentricity of each connector can be corrected.
(2) Loose connections (especially oil inlet passages) at the connections of the tubing, air entering the hydraulic motor or hydraulic oil contamination.
(3) The gap between the plunger and the cylinder bore is increased due to severe wear, which can be reused for plating.
(4) The head of the putter (spherical surface) is heavily worn, and the journal at both ends of the output shaft is heavily worn. Available electroplated or brushed journal position repair.
(5) The influence of external vibrations may even generate resonances. According to the situation, the elimination of external vibration sources may be found. Or the hydraulic motor is not installed firmly, and the cause of the vibration can be eliminated according to the situation.
