Plate and Frame Filter Press Working Principle - Yangzhou Darui
Darui Electric recommends for you
It can be used for on-site oil filtration and oil replenishment of various oil-immersed transformers, oil-immersed current transformers, and oil-free high-voltage circuit breakers. At the same time, it can perform in-situ hot oil circulation drying on previous equipment, and for the on-site hot oil circulation drying of previous equipment, it is particularly suitable for submerged oil, transformers, and oil-free circuit breakers.
This equipment is mainly used to treat unqualified turbine oil, especially for severely emulsified turbine oil. It can quickly remove water, gas, and impurities from the oil. It makes all quality indicators of the oil meet the standards of new oil, ensuring the safe operation of steam turbine units. It can also be used as a sealed oil-immersed equipment for on-site vacuum oil filling, oil replenishment, and vacuum equipment. It can also purify slightly deteriorated transformer oil to meet the qualified oil standards.
The vacuum oil filter can be used for on-site oil filtration and oil replenishment of various oil-immersed transformers, oil-immersed current and voltage transformers, and high-voltage low-oil circuit breakers. At the same time, the vacuum oil filter can also be used for on-site hot oil circulation drying of the above equipment, especially for the on-site hot oil circulation drying of oil-immersed current and voltage transformers and high-voltage low-oil circuit breakers.
When the vacuum oil filter is working, the oil enters the primary filter through the inlet under the action of internal and external pressure difference, and large particle impurities are filtered out. After heating, the oil enters the secondary filtration, and after filtering out smaller impurity particles, it enters the water separator. Because the water separator adopts enhanced hydrophilic and hydrophobic technology, it changes the interaction force between the oil-water two-phase interface, accelerates the movement of fine water droplets in the oil, and coalesces them into large water droplets that separate from the oil and precipitate in the water storage tank. Then the oil passes through the fine filter to remove particulate impurities, and then enters the vacuum tank. Using vacuum flash evaporation technology, the residual trace moisture in the oil is removed. The evaporated water is cooled by the condenser or discharged by the vacuum system. The dehydrated oil is output by the oil pump, completing an oil purification process.
