WORKING PRINCIPLE:when this machine start working, the used oil will be injected into the primary filter under the pressure, the

primary filter will remove the big impurities, then the oil which just contains the particles is heated by the

heater. Then the treated oil enter into the vacuum separator, the vapor is separated from the oil and

refrigerate to water under the process of the lowest-vacuum pressure and the degassing equipments.

The last procedure is that the fine filter removes the particles completely.

ADVANTAGE:Comparing with the single-stage vacuum oil purifier, this machine dewaters, degases and removes the

impurities more quickly, more completely, and improves the oil breakdown voltage much higher. As the

bridge-type vacuum linking system, it is used for filtrating system as well as an independent vacuum

power supply to vacuum oiling of power equipment.

Part II OPERATION PROCEDURE

TESTING:

1. Shut off all valves, connect the outlet and inlet pipes, make sure the outlet and inlet are normal.2. Correctly connect the power which must be the three phase and four lines

3. Launch the vacuum pump, exhaust oil pump, and keep their rotation direction is right, meanwhile

maintain the vacuum-motor and oil pump-motor working normally.

4. Check the interlock between the temperature controller and heater, it is means that the temperature

controller control the heater immediately.

5. Shut off the valve, which connect with the atmosphere; open the pipe valve; start the vacuum pump,

then stop the vacuum pump for five minutes when the max value of the vacuum gauge is steady, and

observe the value of vacuum gauge must be up than 0.001Mpa, if not, you should find the gas leak.

INSTALLATION:This machine should place in the horizontal ground and lay down steadily.

This machine is movable which can move to any where as per your require.

You must choose the correct power, which can support the biggest electric current of the machine.

OPERATION:1. Open the air inlet valve (29), start the vacuum pump (31), observe the vacuum value increasing status.

2. Open the overflow valve, adjust the pressure value at 0.3 Mpa

3. Open the oil inlet valve, when the vacuum value reach to 0.08Mpa

4. Open the oil outlet valve (20 or 22) when the oil enters into the vacuum tank and that the oil level at themiddle of the oil level indicator.

5. Observe the change of pressure gauge (the pressure of exhausting oil is limited between 0 0.4Mpa,

and it is normally 0Mpa when the machine runs), check whether the exhausted oil pump and joints have

leakage phenomena. If the phenomena appear, pls resolve it instantly and clock the overfall valve to

make sure the machine work normally.

6. Adjust the quantity of inlet oil through valve 15 to balance the quantity of inlet oil and outlet oil. Have the

finger is at the middle of the oil level gauge which is on the vacuum tank (when running normally, the

machine is controlled automatically by infrared auto-controller).

7. When oil circulate normally, open auto-control heater. Note: before open the heater, have the

temperature is between 45 65 (65 is best). Then decide whether open manual heater according

the quantity of treated oil and the temperature of the environment (it mainly suits to ZY, ZYA-100 and the

plants which are lager than ZYA-100).

8. If the machine work normally and the oil has circulates many times, pls take some sample at the

sampling valve to test the treated oil.

9. Adopt the machine to filter the oil which is injected into transformer, mutual inductor, bushing. The oil

doesnt need assistant vacuum source and assistant heater. The machine has vacuum resource and

heater whose power has satisfied the need of drying device. Note:

When use the spraying method or pouring oil method to dry the oil, must have the whole filter in the oil.

When scalary circulation purification, pls control the oil inlet speed, the oil inlet temperature, and thescalary circulation time according to the related rules.

b) There should be some eligible oil in vacuum tank before the machine start working. The measure

makes sure the oil level balance of transformer treated wooden tie when the machine is working.

INSTRUCTION:

1. The environment temperature is between -25 45 when the machine is working.2. The altitude height of the working point will influence the vacuum degree of the machine directly. The

higher the altitude height is, the lower the vacuum degree is (negative value).

3. The used oil can not be too dirty ( the oil dont have too many impurities), otherwise it should use other

purification plant to filter sufficiently such as JL Portable Oil Purifying and Oiling Machine. The measure

avoids influencing the efficient of degassing and the lifetime of the machine.

STOPPING:

When the oil has been filtered or the machine need to be stop at the midway:

1. Stop heater, and close the oil inlet valves 15,20,22 after continue to inject oil 3 5minutes.

2. Close vacuum pump. Close vacuum pump valve 29 and open vent valve 7 in order to release vacuum.

3. When finish exhausting the oil in vacuum tank, close the exhausted oil pump.

4. Open the valve 1 which is at the inferior extremity of the cooler to drain away the rest oil and water.

Note: close the valve 1 after drain away the rest oil and water in order it can be used next time.

5. If have emergent situation, press the emergent button and the machine has no power. If want to open

the machine, pls round the emergent button according to the clockwise direction so that open all control

button.

ATTENTION:

A).Live-line operation can only be conducted on sunny daysB). Connecting inlet and outlet pipes must be instructed by electric engineers.

C). Before live-line operation, the oil purifier must be in a good condition (the heating, vacuum generating,

and filtering system)

D). Open the outlet valve before starting the oil pump, or the filter will be damaged.

E). There must be oil in the heating vessel before heating, or the heater will be damaged.

MAINTANCE:

1. After a certain period of running, the machine should be checked to see whether:The electrical control system is safe and reliable;

The temperature controller is sensitive, reliable and accurate;

Oil seals of the pump shaft are broken with leakage;

There is any blockage with the running system and any abnormal noise with pumps or related motors;

There is any air or oil leakage with the oil running system and at sealing joints.

2. After each 3000 hours running, grease shall be replenished to prevent motors from being burnt.

3. Special vacuum pump oil or lubricating oil N46 should be used fro the vacuum pump and oil replaced or

replenished if necessary at any time.

4. If the machine will not be used over 1 month, Place the machine in a dry environment with the panel

door and all valves closed, and the machine proper protected by a covering.

ONLINE OPERATION:

PREPARATION:prepare some eligible oil which is about 5 6% content of the transformer and put the oil near the purifier.

The oil outlet valve in the bottom of transformer should match the oil inlet pipe of the purifier. If they can

not be matched, pls connect a new oil outlet pipe.

The oil purifier should have some eligible oil whose quantity is half the content of the vacuum tank

(pressure value is greater than 50KV).

Open the treated wooden tie cover of the transformer, have the oil outlet pipe inject into the oil level of the

treated wooden tie, and use the clean filter paper or membrane to pressurize the treated wooden tie

cover.

Have the oil inlet pipe inject into the oil tank, which have some eligible oil.

Open the oil outlet valve at the bottom of the transformer, and exhaust 3 5%oil of the transformer(the

3 5%oil is mainly impurities and water, pls receive it separately).

While operate the step 6, the purifier should be vacuum( no lower than 0.09Mpa), and supply sufficiently

the oil in treated wooden tie of transformer.

After exhaust 3 5%wast oil through the oil outlet valve at the bottom of the transformer, connect the oil

inlet pipe to the oil outlet valve.

Now, the purifier can work normally.

NOTICE:

1. If the weather is sunshine, the on-line work can be running.2. Pls connect the oil inlet pipe and oil outlet pipe under the live guidance of the electric engineer.

3. Before on-line work, the functions of the purifier must be fine such as heating function, vacuum function,

filtering system.
