7. Troubleshooting
If pumping performance remain worse,please find below solution for your
consideration
Problem Reason
Remedy
Can’t start
or No dreg
pumped out
no driving hydraulic oil
Start the power device,check if flow range
and pressure are in line.
Fault for hydraulic pipe
coupling or hydraulic tube
Ensure the running and switching on for
the hydraulic power device,and no blocking
in connecting hydraulic pipe; Ensure the
availability of the hydraulic pipe coupling
unit.displace hydraulic pipe or coupling
unit.
Impurity blocked impeller
or disabled impeller
Clean the impurity which blocked impeller
or displace impeller
Disabled hydraulic motor. Displace or maintenance hydraulic motor.
Worse
performance
for pumping
The flow range or
pressure of driving
hydraulic oil is out of line
check if flow range and pressure are in
line.
Diameter of hydraulic oil
pipe and coupling unit is
getting smaller
Diameter of hydraulic oil pipe and
coupling unit is not as standard
Blocked discharge
Bending or flattening of the tube of
discharge; Consolidated impurity inside
tube.Crossed pipe for discharge.
excessive wearing
impeller
Displace impeller
