Calibration

system

wrong

Evaluate and correct it

Medium viscosity is too

high

Improve temperature of product or

lower the viscosity. Increase the

size of pump and pipeline.

Medium cavitations

Increase the pressure of suction,

and shorten the suction pipe.

Flow

becomes

lower

gradually

Check valve leakage

Clean or change the valve

Suction pipe leakage

Find the leakage position and

solute the problem.

Filter is blocked

Disassemble the filter; clean or

change it.

Medium is changed

Check the viscosity and other

parameters

Blowhole of the offering

tank is blocked

Open the blowhole

Flow is

unstable

Suction piping leakage

Find the leakage position and

solute the problem.

Medium cavitations

Increase the pressure of suction and

shorten the suction pipe.
