The plate press Transformer Oil Filter Machine is mainly used in power plants, power stations, industrial and mining enterprises' substations (rooms) lubricating oil depots, tractor stations, petroleum, chemical, metallurgy, defense industries and other units to filter transformer oil, insulating oil, cable oil, turbine oil, etc. It is the ideal equipment for vacuum transformer oil purifier and turbine oil purifier to pre-filter the moisture and impurities in gear oil, machine oil and other lubricating oil. Due to the limitation of the gear structure and device structure, it is not suitable for high-viscosity oils; for non-slip oils such as gasoline and kerosene, special materials can be used with special motors according to user needs. When the oil viscosity is high, the oil should be heated first to reduce the oil viscosity and facilitate filtering. If the oil is too dirty, you can first use the precipitation method to remove a large amount of impurities before filtering with this press type transformer oil filter machine.

The principle of plate and frame press Transformer Oil Purification Machine

The plate and frame press type transformer oil filter machine is a movable device composed of filter bed, oil pump and coarse filter.

The filter bed is a continuous operation. Under pressure, the dirty oil is pressed into the filter group that is filtered to the side. It is composed of a set of filter plates and filter frames alternately arranged in sequence, and includes a manual screw pressing device and pressing The composition of the board. The sides of the filter plate and the filter frame are supported by "ears" on the support plate of the frame. The filter plate and the filter frame are lined with filter paper or filter cloth as the filter medium. With the pressure of the pressing device, the filter plate and the filter The frame is pressed against the filter paper or filter cloth between the fixed thrust plate and the filter frame to play a filtering role. There are two liquid holes at the corresponding positions of the filter plate and the filter frame. When compressed, they form two complete channels. One side of the ears is triangular and the dirty oil is introduced. After being filtered by the filter chamber, the corresponding channel is from the other side.

Dirty oil is distributed to each filter frame through the input channel during filtration by Press type Transformer Oil Purification Machine, passes through the filter paper and then enters the liquid hole of the filter plate. The clean oil is collected in the output channel and discharged outside the machine. While the dirt remains on the surface of the filter paper, a small amount of water in the dirty oil is absorbed by the capillary in the filter paper. When the filter residue on the surface of the filter paper gradually thickens and the water content in the filter paper increases, the filtration resistance increases. When it increases to a certain extent (Generally 0.2~0.35Mpa) The filtration should be stopped, and the filter paper should be replaced or cleaned before continuing to use.

The gear pump and the motor are connected with elastic rubber pads. In order to avoid mechanical accidents caused by excessive pressure, a safety valve is installed at the lower part of the oil pump (the product has been adjusted to the specified maximum pressure of 150% PN when it leaves the factory). The safety valve can be set to a lower value according to user needs, but it is generally not allowed to adjust to exceed the specified maximum pressure value.

The gear pump and the motor are installed under the filter bed of Transformer Oil Purification Machine, and the liquid output by the oil pump is delivered to the filter part through the discharge pipe and the thrust plate. The gears of the gear pump are supported by rolling bearings, which are lubricated by the oil delivered by the oil pump itself.

The coarse filter is installed at inlet port of Transformer Oil Purifier, and its function is to prevent large particles of impurities from entering the oil pump and destroying the oil pump. When the bolts on the coarse filter cover are unscrewed and the coarse filter cover is removed, the filter screen can be taken out and cleaned directly. When the coarse filter is full of dirt, not only will the oil filtering capacity drop rapidly, but the filter screen may also be damaged. Therefore, you should always pay attention to cleaning the coarse filter screen. When there is oil in the tank, the oil return valve can be opened to suck out the oil and prevent the oil from spilling out of the Transformer Oil Filter Machine
