Learn Xi about the operation skills of small oil purifiers

The small oil purifier adopts a two-stage high-efficiency vacuum unit to quickly improve the overall vacuum degree of the system, and efficiently and quickly remove water, gas, and particulates in the oil at a lower temperature. It can effectively shorten the transformer installation and maintenance period. Especially for use in areas at higher altitudes, it has the ability to circulate drying hot oil for electrical equipment and vacuum oiling. Vacuum pumping and other functions. Regardless of whether the new refined oil is still in operation, in the process of work, no matter how careful the transportation turnover, installation and operation are, it is still impossible to avoid the oil being polluted When the pollution is formed, the solution to the efficient filtration of the oil products.

Small oil purifier operating procedures:

Before operation, the filter paper of the hole will be carefully sandwiched between each filter plate and filter frame, the number of filter paper in each layer is generally 1-2 sheets, depending on the requirements of filtration and the quality of the filter paper.

The filter paper should be dried before use, and the drying temperature is about 120°C.

When using used filter paper, the filter paper must be dried and should not be damaged, pay attention to the side with filter residue (that is, the dirty side) should be placed on the filter frame, not the filter plate, so as not to wash down the filter residue during this filtration and contaminate the filtered oil

When the filtration pressure is high and the filter paper is found to be broken, a filter cloth can be lined on one side of the filter plate to increase the strength of the filtration.

After putting the filter paper, turn the handwheel to press the filter plate tightly, when pressing the plate, only one person is allowed, and the compression handle cannot be extended to compress, so as not to damage the machine.

Close the sampling nozzle, if the user has a valve on the oil discharge pipeline, the valve should be unscrewed. Turn on the power supply of the motor, so that the oil purifier works, the normal working pressure of the oil purifier changes with the viscosity of the oil filter, and the resistance of the discharge pipeline, generally in the range of 0.05-0.3MPa, the initial pressure of filtration is low, with the increase of filtration time, the increase of water absorption of filter residue and filter paper gradually increases, and the filter paper should be replaced when it reaches a certain degree (varies with the user's requirements for oil).

During the oil filtration process, when the oil sample is extracted, the grease nozzle can be unscrewed to take the sample.

When stopping, open the inlet valve first, stop the machine after the oil outlet pipe is oil-free, close the oil inlet and outlet valve, stop the oil pump, loosen the pressing device, take out the filter paper piece by piece, clean the filter paper and the filter residue in the filter frame, replace the filter paper and clamp it again, and cover the oil tank. Finally, clean the coarse filter, re-cover and tighten the bolts after cleaning, and use it again next time.
