Double stage vacuum oil filter oil filter high automation, overpressure stop and alarm, safe and reliable, flange connection without leakage. The filter adopts strong wind condensation technology to enhance the effective output power of the equipment and protect the vacuum pump system. Filtering system step by step encryption, high pollution load, long service life. Advanced automatic level control system, automatic heating control, automatic pressure protection device, can really achieve man-machine separation. Special pumps for vacuum oil filter are supplied by large scale oil pump factories which export without inspection and sell directly abroad. Automatic control system, can adopt manual, automatic two control. The majority of users can choose two-stage vacuum and four-stage filter according to the actual technical requirements. After filtration, turbine oil reaches the new national oil standard.

The daily maintenance of the two-stage vacuum oil filter can improve the working efficiency of the equipment and prolong the service life of the equipment. When the equipment is out of service for a long time, all the oil in the memory of the machine should be drained and then all the valves should be closed. The vacuum pump oil shall be replaced every month (1# or 0# special vacuum pump oil shall be used) to deal with too much water-containing oil. The vacuum pump oil shall be replaced every time. The vacuum pump oil level shall be checked before starting up each time and the vacuum pump shall be turned by hand before starting up. The pressure of the fine filter tank shall be removed when the machine stops after alarm, and then the fine filter core shall be cleaned or replaced. Refuse to load the fine filter element into the coarse filter tank. The filter element of small oil tank should be cleaned once a month.

Two-stage vacuum oil filter multistage precision filter step by step encryption

The whole structure of the two-stage vacuum oil filter can be made into mobile, fixed, (half shaft or double shaft). Can be produced completely closed, cover eaves type, canvas awning. You can choose the color of the device as you want. It can also be used for vacuum oil filling, vacuum drying and hot oil circulation of transformer. It is more advantageous to use this series of models in high altitude areas.

Double-stage vacuum oil filter can be equipped with PLC intelligent control, touch screen operation and dynamic display according to the needs of users. The main power components, filtration equipment and electrical components can be imported with high quality to improve the performance of the equipment. On-line moisture detector is optional. Optional inverter, according to the need to choose the flow. Optional flowmeter with accumulation function. Optional external pair transformer pumping system.

Two-stage vacuum oil filter advanced degassing three-dimensional flash technology, can quickly remove water, impurities, hydrocarbons and other harmful components in the oil. It improves the flash point and compressive strength of insulating oil. Can meet the installation or maintenance site of the transformer body vacuum and vacuum oil. Multistage precise filtration step by step encryption can effectively remove the mechanical impurities in the oil. Automatic thermostatic control, automatic level control, automatic defoaming, automatic pressure protection. It can filter oil online and run without any person. The running state is shown by the indicator light. This machine is humanized design, low noise, easy to operate, long maintenance interval, low energy consumption to save operating cost. The whole machine is equipped with interlocking safety protection, oil drainage system, vacuum system and heating system to avoid misoperation.

The function of two-stage vacuum oil filter

The ambient temperature of the two-stage vacuum oil filter should be in the range of -25 ~ 45℃. The altitude of the site will directly affect the vacuum of the machine. The higher the altitude, the lower the vacuum (negative value). The oil to be treated can not be too dirty (that is, the impurity particles in the oil is too much), otherwise, must first use other filtration equipment (such as my factory production JL series portable type filtration tanker) fully filtered, so as not to affect the degelling efficiency of the oil machine or block filtration components, affect the life of the oil machine. To stop when the oil has been treated or when it needs to stop running. First stop the heater, continue feeding for 3 ~ 5 minutes and then close the feeding valves 15, 20 and 22. Close the vacuum pump, vacuum pump valve 29, open exhaust valve 7, remove the vacuum. When the vacuum tank is empty, close the pump. Open valve 1 at the lower end of the cooler and drain off the residual oil or water inside. Pay attention to close valve 1 after unloading for next use.

The two-stage vacuum oil filter adjusts the opening amount of the oil inlet valve 15 to balance the oil inlet and outlet, so that the oil level gauge on the vacuum tank is in the middle position (automatically controlled by the infrared automatic control instrument after normal operation). When the oil circulation normal, can start the automatic control of heater, attention should be taken before start the heater temperature control in 45 ~ 65 ℃ range of self-control, at 65 ℃ for zui better state, and then based on what amount of crude oil and the surrounding environment temperature to decide whether to open the manual heater (mainly applicable to ZY, ZYA – 100 type of equipment). After the machine runs normally and the oil is circulated several times, the sample can be taken from the sampling port for testing. When the transformer, transformer and bushing are injected with oil by this machine and vacuum clean oil is dried, auxiliary vacuum source and auxiliary heater are generally not needed. The vacuum source and heater attached to this machine can meet the requirements of drying equipment.

Two-stage vacuum oil filter is suitable for large power transmission and transformation equipment above 110KV and national main transformer grid. High vacuum, limit vacuum ≤5Pa, working vacuum ≤35Pa, large pumping speed, pumping rate ≥330L/S. The combination of stereo flash and plane flash makes dehydration and degidation more complete. Solenoid valve combined with the control mode. Vacuum oiling and vacuum drying transformer. The machine can filter oil with live for more than 300 hours. Can meet the installation or maintenance site of the transformer body vacuum and vacuum oil. The introduction of Japanese low temperature oil technology can effectively remove the moisture in the oil and improve the pressure resistance.
