Replace PALL Line Filter Element HC9600FKN13Z

Replace the PALL pipeline filter element HC9600FKN13Z, used for the high pressure filter of the oil pump of the EH oil station of the steam turbine of the power plant. Filter out impurities in the oil, filter material: glass fiber filter material inside and outside nylon mesh, deep dirt holding, high filtration efficiency

The high-efficiency filter in the clean room is the key equipment to achieve high-cleanness air purification. Therefore, after the high-efficiency filter is installed or replaced, the installation and connection of the filter must be leak-checked to ensure that the cleanliness of the clean room meets the requirements. The maximum allowable number of suspended particles is ≥0.5μm 3500 under the state of hundred-class cleanliness. The following introduces the leak detection test method of high-efficiency filter

Applying the principle of light scattering, the photomultiplier tube is used to receive the light reflected by the dust particles to determine the size and quantity of the dust particles, and analyze the accumulation and digital display.

experimental method:

1 Environmental conditions: the temperature is controlled at 18-26℃; the relative humidity is controlled at 45-65%

2 Test status: static test, no more than 2 indoor testers

3 Pressure difference: For rooms with different cleanliness in the room, the static pressure difference is ≥5Pa, and the static pressure difference between the clean area and the non-clean area is ≥10Pa; the room with a large amount of dust during the process and other rooms should maintain a relative negative pressure
