Application of Transformer Oil Vacuum Filter:
ZJBDegassing, oil filtration, and micro water removal transformer vacuum oil purifierMainly used for purifying unqualified transformer oil, transformer oil, switch oil and other insulation oils in power sector enterprises, it can also be used for vacuum oiling of transformers and drying of various damp power equipment.
Features:
This machine has dehydration and degassing three-dimensional flash evaporation technology, which can quickly and effectively remove harmful components such as water, impurities, and hydrocarbons from oil.
● Improve the flash point and withstand voltage strength of insulating oil.
Capable of meeting the requirements for vacuum pumping and vacuum oil injection of the transformer body during installation or maintenance.
Multi level precision filtration with step-by-step encryption can effectively remove mechanical impurities from oil.
● Automatic constant temperature control, automatic liquid level control, and automatic pressure protection.
It can filter oil online and operate without human intervention. The operating status is displayed by indicator lights.
The machine is designed with humanization, low noise, easy operation, long maintenance intervals, and low energy consumption to save operating costs.
The whole machine is equipped with interlocking safety protection, and the oil discharge system, vacuum system, and heating system are interlocked to avoid misoperation.

Mobile vacuum oil filter execution standard
ZJB strictly adheres to national standards, guided by the "Guidelines for the Use of DL/T521 Vacuum Oil Purifiers" and the "Mechanical Industry Standard for Vacuum Oil Filters JB/T 5285". In order to meet the needs of on-site inspection and maintenance of various high and low pressure oil carrying equipment by maintenance departments, our design features small size, light weight ratio, easy mobility, low noise, long continuous working time, stable performance, and convenient operation. It is an ideal equipment for filtering moisture, gases, and impurities in transformer oil, insulation oil, and other fluids in various power plants, power stations, substations, electrical manufacturing plants, refineries, petrochemicals, and other industrial and mining enterprises.
