Operation operation of transformer oil filter

1. connect the oil filter to the power supply and connect the oil pipe. Note: before using, we should know the impurity in the oil well. If you pump oil from a large number of precipitated oil tanks or oil tanks, do not insert the direct oil pipe to the bottom. If necessary, add the pre filter.

2. the cooling water is connected to the cooling water source, and the principle of the lower flow is followed, and the small flow is circulating in the water. If conditions are not allowed, we can use the vacuum suction method to add cooling water to the condenser after start-up. The method is to connect the valves of the vacuum tank with the cooling water outlet valve by the hose, and the inlet valve is connected with the cooling water, and the vacuum pump is opened. If the amount of water in the oil is less or the time of the equipment is put into use is short, the cooling water can also be used.

3. start the vacuum pump, pay attention to the increase of the vacuum degree, when the vacuum reaches -0.06Mpa, slowly open the oil intake valve equipment into the oil.

4. when the oil enters the vacuum tank, the oil level reaches the middle position of the oil level meter, opening the oil valve, starting the oil pump, and starting the oil out of the oil outlet. Please note: must be in the open out of the oil valve, to start the pump, or it may be broken or damaged filter filter.

5., the transformer oil filter can observe the change of the pressure gauge (the oil pressure should be limited to 0 ~ 0.3Mpa, which can be achieved by adjusting the operation value of the pressure controller), and check whether there is oil leakage in the oil pump and the pipe joint. If necessary, we should remove it immediately, so as to ensure the work of this machine.

6. with the increase of vacuum regulating valve to the vacuum in the town, -0.06 ~ -0.08Mpa; adjusting the amount of oil, oil import volume reached the relative balance, ensure the stability of the vacuum tank oil level in the middle position (after the normal operation of the infrared liquid level control instrument automatic control).

7. when the oil is circulating normally, the heater can be started. The temperature control instrument in automatic adjusting control range (digital temperature controller set method: dial switch to turn the knob until the need to limit, lower limit value; and then switch to the upper limit, according to the same method to get maximum value; then switch to measurement file), recommended the upper and lower limits the difference between the value of 1~3 degrees can be recommended, the heating temperature is 55~65 DEG C; and then open the heating switch, the other group according to the treatment of oil heater can open is the amount of the ambient temperature and the level of decision (for two or more groups of heating).

8. the machine operates normally, and after several times of oil circulation, the sample can be sampled from the sampling port.

9. Ruoyu emergency situation, you can press the emergency stop button, and turn off the heater, and close the oil inlet valve, transformer oil filter press release the vacuum, to prevent the oil too much; if the fault to boot removed, must rotate clockwise emergency stop button and can open all the control button.

10. this machine adopts of transformer, transformer, casing and other oil and oil vacuum drying, does not need auxiliary vacuum source and auxiliary heater, the machine is attached to a vacuum source and the heater, the power can satisfy the need of drying equipment, just pay attention to: (1) spray or drench the oil when dry. The device should be the core are poured into the oil phase; circulation purification (i.e., layered oil drying) to control the oil inlet speed, according to the relevant rules in the cycle time of oil temperature and stage. (2) there is a certain amount of qualified oil in the vacuum tank before the oil machine works, so as to ensure the balance of the oil level of the transformer pillow when the oil machine works.

11. Ruoyu emergency situation, you can press the emergency stop button, when the machine is not energized; to boot, must rotate clockwise the emergency stop button, can open all the control button.

12. please refer to the specifications of the dielectric strength tester (such as), vacuum pump and so on. Internal circulation operation: when dealing with a large amount of oil and oil dehydration temperature is difficult to achieve the ideal, can start the cycle, in the premise that the vacuum operation in the tank has been fully into the oil (under appropriate up on the fixture can be opened, infrared) circulating valve, close the inlet valve and outlet valve, let the oil in for full cycle several times, when meet the requirements after the open valve, and close the circulation valve disposed of, let oil send oil machine. Single pump gas: This machine can also be used for equipment refueling. The inlet pipe is connected to the pipe inlet of the single suction oil valve, and the valve is opened. The outlet position is unchanged. After the oil pump is started, the oil is sent to the oil tank through the two stage filter and the fine filter to the fuel port.
