How to maintain and repair the special Filter Press for edible oil in use to prolong the life of the Filter press? The first is the maintenance, understand the maintenance of the special Filter press for edible oil to avoid problems, and how to correctly repair when problems occur to ensure life.Edible oil special filter press should be done during use of the maintenance matters:

1, the filter Press FIlter cloth selection must meet the characteristics of the filter material and the technical requirements of the equipment, the new filter Press Filter cloth before use first shrinkage, the diameter of the hole should be smaller than the pore diameter of the Filter Plate, the supporting filter plate cloth hole and the plate hole should be relatively concentric, the feeding hole cloth should be close to the cylinder wall, otherwise it will be easy to cause the filter after the filtrate is not clear or the filtration efficiency is low and the cloth cylinder rupture and other unexpected filtration effects and filtration purposes.

2, in the edible oil special filter press filtration in the early stage, the filtered liquid will be a little turbid, wait until the filter cloth above the formation of a layer of filter cake, it will become clear, if it is said that in the filtration process, the filtrate has been turbid or by clear to turbid, we need to consider whether the filter press filter cloth is damaged or whether the cloth hole and plate hole are caused by deviation.

3, mechanical compression transmission components and gearbox must be added with sufficient lubricating oil, hydraulic pressure to check the oil storage capacity of the tank, as well as the working pressure of the hydraulic station, hydraulic oil should be replaced once a year, when replacing the Hydraulic System to do a comprehensive cleaning. The working pressure of the hydraulic station should not be less than the higher working pressure of the cylinder, but it can not be the allowable value of the regional pressure, if the pressure is relatively large, it will damage the parts, and if it is relatively small, it will cause greater leakage.

4. When the filter filter cloth is replaced, the feed valve should be closed and the feeding should be stopped, so that the filter cloth can be replaced.

5, compressed air valve Amen and slurry and wash liquid control enabled, to be carried out according to the operation, can not be enabled at the same time, when the diaphragm is squeezed and squeezed, the compressed air pressure can not exceed the filter pressure.

Edible oil filtration is different from sludge sewage filtration treatment, edible oil filtration is also a kind of Solid-liquid Separation, so the effect of the special filter press for edible oil is from the clarity of the filtered oil.
