phenomena

reasons

handling measures

the waist wheel does

not run

1、 The dirt blocks the pipes

2、The tested liquid is frozen

1、 To clean the pipe、filter and flow meter

2、 To resolve the liquid

The waist wheel runs

but the needles do not move or stop at times

1、The fork of gauge outfit is out of line

The dirt goes into the

speed charger of gauge

outfit
2、The needles or counter is jammed

3、The speed charger disjoints

To discharge the gauge outfit and to use hands to run the fork.If the instrument moves, it proves that the connection of gauge outfit and bearing is broken; if not, we have to check step by step.

Turning to sealed

coupling shaft with oil leakage

The gasket wears down

To tighten the gland or replace the gasket

The difference between the compensator and the small flow is partial

to be negative

The waist wheel collides with the shell, along with the abrasion of bearing or the immobilization to the main body of drive gear moves the position

To change the bearing and check the drive gear to see if the wheel body works; to fasten the

screw of gear to see whether it loosens or not

The error changes greatly

1、 The pulsing of liquid is rather big

2、 It contains gas

1、To reduce the pulsing

2、To add the getter device
