Fault phenomenon | 原因分析 | Exclusion Method |
Output speed and output torque are low | (1)Severe leakage at the joint surface | (1)Fastening joint surface |
(2)The sealing of the pipe joint is not tight, and under negative pressure, air is drawn in. | (2)Tighten each pipe joint to improve air tightness |
|
(3)Oil contamination, the internal passage of the axial piston motor is blocked. | (3)Disassemble, carefully clean, and replace with clean oil. |
|
(4)The internal leakage of the motor is too large ①Oil viscosity is too low ②Internal parts are severely worn | (4)Handling Method ①Replace with oil of appropriate viscosity ②Repair or replace worn parts |
|
(5)Insufficient fuel supply ①Filter blockage ②Oil viscosity is too high ③Internal component wear | (5)Handling Method ①Clean and replace with clean oil ②Replace with oil of appropriate viscosity ③Repair or replace relevant parts |
|
(6)Pressure control valve failure | (6)Repair or replace |
|
Noise is too loud | (1)Motor internal parts damaged | (1)Repair or replace relevant parts |
(2)同1.(2) | (2)同1.(2) |
|
(3)Oil viscosity is too high | (3)Replace with oil of appropriate viscosity |
|
(4)Poor coaxiality of the coupling | (4)Reinstall, adjust and tighten |
|
(5)Influence of external vibrations | (5)Take measures to isolate from Zhenyuan |
