ZL-50 efficient vacuum oil filter series overview

1 Performance overview:
ZL highly effective vacuum oil filter series adopts physical means, which do not effect the oil composition and the performance. It can rapidly remove moisture, impurities and gases (acetylene, hydrogen, methane, etc.)and other harmful ingredients contained in oil, to improve the breakdown voltage and insulation performance of the oil. So as to effectively guarantee the normal operation cycle of oil equipment, and avoid the accident.

2 Equipment features:

 1. Dehydration and Degassing ability.

(1) The equipment adopts large displacement of the vacuum pump to pump the vacuum system, which ensures that the water vapor and other gases in oil be removed; It also ensure the entire system has been maintained working on the conditions of a very low pressure .

(2) Adopts the advanced technology of the short-film evaporation and molecular separation technology, which rapidly remove a large amount of water in oil. The effective removals of trace moisture ensure the water content lower than 15ppm.

2. An exceptionally strong ability to filter out impurities.

The equipment own progressive encryption level filtering system settings. Primary filter with stainless steel twill mesh imported from Japan, which can be cleaned repeatedly to reduce the operating costs of equipment. Refined filter adopts domestically produced high-quality polymer filter and the filtration precision is up to 3μm, which can carry a large amount of pollutant, and remove the fine particulate impurities effectively. The cleanliness of oil after treated is up to NAS6 (NAS1638 level) or above.

3. be equipped with proper protective equipment, which makes the full realization of unmanned, automatic operation come true.

The implementation of a comprehensive protection with equipment temperature, liquid level, pressure, power off, super-pressure, under-voltage, overload by each power element, effectively prevent the accident and ensure the function normally.

1) The use of advanced temperature control devices to achieve range of temperature control equipment, automatic adjustment, effectively  prevent the phenomenon of an aging oil caused by the device heating temperature is too high for man-made improper operation.

2) Oil level control device equipment to achieve the oil level range control, automatic adjustment; prevent the oil overflow phenomenon effectively,which due to man-made improper operation.

3) Well-established pressure control device.

  After the equipment is running for some time, and the filter net is plugged by impurities leading to pressure of the oil pump mouth increasing, then the pressure rose to point set by pressure sensor devices, so the machine will give signal and automatically stop working, which effectively prevent the accident.

4) It owns simple operation and easy maintenance to humane design.

5) It uses condensation and cooling technology to cool and dewater. It increases the effective output power of devices, greatly extending the service life of vacuum pump.

3 An overview of the working principle:

The oil firstly going through the mouth into the beginning of the filter, large particles and impurities are retained; by the primary pressure, the oil enter the heater for heat exchange heat to enhance the mobility of oil, which is good for next step of treatment; the heated oil under the pressure continue to enter the special character of the low pressure vacuum separator with the separation technology and the elimination of inter-molecular force for transformer oil analysis, so that the dissolved water, free water, dissolved gas and free gas in oil quickly break the film elements and precipitation. Then it uses short-range, thin-film  evaporation technology for vacuum detain the water and flash three-dimensional evaporation; these water vapor and other gases under at a very low pressure are quickly discharged by vacuum pump, thus completing the oil dried degassed dehydration. The oil after degassed and dewatered through the oil pump flow into the fine filter, and filtering the impurities, finally the oil out of the mouth is clean oil.

The high-temperature water vapor and other gases evaporate in the vacuum separator through the condenser, heat exchange; coolers cooling three processes, then most of the gas was restored to the water and stored in reservoirs, and then removed. The dry gas after cooling and dehumidifying is pumped out by the vacuum pump, so as to protect vacuum pumps and prolong the life of vacuum pump.
