when a hydraulic motor is working fine, why is the noise getting louder? I haven't done anything, "said Mr. Li, who came to Ausnutria to repair hydraulic motors. There are many reasons for the high noise of the hydraulic test bench motor,
The reasons for the loud noise of hydraulic motors are:
① The seal is not tight, and there is air invading the interior
② The hydraulic oil is contaminated and there are bubbles in the stick
③ Oil temperature too high or too low
④ The coaxiality of the coupling exceeds the tolerance
⑤ Hydraulic oil drilling too large
⑥ The radial dimensions of the hydraulic motor are severely worn out
⑦ The blades are worn out
⑧ Poor contact between blades and stator, with collision phenomenon
⑨ Stator wear

⑤ Hydraulic oil drilling too large
⑥ The radial dimensions of the hydraulic motor are severely worn out
⑦ The blades are worn out
⑧ Poor contact between blades and stator, with collision phenomenon
⑨ Stator wear
Methods for eliminating loud hydraulic motor noise:
① Check the sealing of relevant parts and tighten all connections
② Replace clean hydraulic oil
③ Check the working condition of the temperature control components
④ Correction of coaxiality
⑤ Replace the oil with a lower viscosity
⑥ Grind the cylinder bore and reassemble the plunger
⑦ Repair or replace as much as possible
