Troubles

Likely reasons

Troubleshooting

1

The vacuum inside the 1^st coalescer is over -0.05Mpa

The block of the Suck-in Pipes

Clean the Suck-in Filter

2

The loss of the vacuum of the 1^st coalescer is over -0.01Mpa

Out of Bilge Water

Cease the device and start when water is there

3

Frequent stop and start of the feeding pump

Failure of the vacuum pressure protect

Check the time delay relay in the electric control box

4

The shock and noise of the feeding pump

Out of water

Pour into water or check whether Vs3 is opened

Over pressure

Check whether the pipes after the pump is unblocked

5

The progress can’t be operated as designed

Failure of the Pneumatic Valve

Check whether the on or off condition is normal, then check the electric control system.

6

The bilge alarm can’t control the solenoid valve

Failure of the bilge alarm

Check and repair the bilge alarm

7

The pressure differences of the 1^st and the 2^nd stages is over 0.1Mpa

The block of the 2^nd stage filter core

Replace it with a new one

8

The 2^nd pressure meter is over 0.2Mpa

The discharge valve of the concentrated liquid is not opened

Open it and adjust it

The penetration rate of the membrane is too small

Clean it or replace it

9

The oil content of discharge water is always over board

The separation rate gets lower

Clean the device completely

10

It can’t discharge oil

Be used for a long time of the liquid lever relay is destroyed

If the liquid level relay works normally, take the level probe out and rub it bright

11

The oil content meter is showed to “EE”

The glass tube is polluted or chapped

If the glass tube is intact, please clean it with a brush

12

The showed valve of oil content meter is changing all the time, and the valve fluctuation is big

The air the device hasn’t been emptied

Wait for 10min, check whether the valve VS7 is opened, if VS7 is closed, please open it

13

Feeding pump doesn’t work

The air is not enough

Provide the compressed air with pressure of 0.4 Mpa

Check whether the indicator lights of VS1 and VS2 on electric control box are lighting

Check the switch of 《water feeding, back flushing, oil discharge》is turned to manual position, if it is on manual position, it can operate after the indicator lights of VS1 and VS2 are went out.

The pressure of vacuum pressure gauge is too high

Check whether the valve VS7 is opened, if VS7 is closed, please open it

JYB1，JYB3 level controllers are destroyed

If they are destroyed, please replace them.

14

The pneumatic valve can’t be started up

The solenoid valve has been destroyed, or the device hasn’t been used for a long time

Check the outlet of solenoid valve, if there is no air ejected, it is destroyed, please replace it. If the solenoid valve can work normally, provide compressed air of 0.8Mpa to open pneumatic valve, then resume normal pressure

15

Safety valve jumps

Outlet valve has not been opened,filter has been blocked

Open outlet valve and replace fitter
