| (一) Pump breakdown reason judgement method and countermeasure |
| OTHER |
Situation |
Possible Reason |
Solving Method |
| 1 |
If the pump dose
not supply oil |
1.The rotation direction is
opposite |
Inspection motor direction,correction |
2.The pump axie center does
not transfer |
Check the junction box and key |
| 3.The oil filter blocks |
Cleans the oil filter |
| 4.The oil filter distortion |
Change |
| 5.The oil viscosity too is high |
A.Change oil B.Heats up the cold oil |
6.The oil suction pipe leaks
air |
A.Spreads the grease to block B.Change |
7.Blots the net not to sink to
below tne oil level |
Increase movement ol to liquidometer on between
lower limit |
| 2 |
If the noise
is very big |
1.The oil filter blocks |
Cleans the oil filter |
| 2.The oil viscosity too is high |
A.Change oil B.Heats up the cold oil |
3.Air entrainment from the
front cover of the pump |
Spreads the grease to discover to the seam leaks
the biowhole improvement |
| 4.Air bubble in the oil |
Ine on return pipe must smk to below the on level |
| 5.Oil mass insufficiency |
Inecrease movement oil to liquidometer on
between lower limit |
6.Sends out the noise from
the pipe connection place |
Check and see if the connection part has
damages |
7.Mtenor or/and exterror
damage on oil pump |
Replaces the oil pump |
