Description
Technical Field
The invention relates to a nondestructive pleating process for a filter material.
Background
In a hydraulic and lubricating system, oil pollution is the most main factor influencing the service life and the operation reliability of elements of the hydraulic and lubricating system, and the excessive solid particle pollutant in the oil can cause the abrasion of the surfaces of moving pairs of the elements, reduce the performance of the elements and cause the failure of the elements. The most direct and effective method for solving the problem of oil pollution is to filter solid particles in oil by using a filter element made of a high-performance filter material, and the high-performance filter material has the characteristics of high filter precision and large pollutant carrying capacity and can effectively intercept the solid particles in the oil. The high-performance filter element is used in the system, so that the oil quality can be effectively improved, the abrasion of system elements is reduced, the replacement times of the filter elements are reduced, and the operation cost is saved.
At present, glass fiber filter materials are used as high-performance oil filter materials, and the glass fiber filter materials are low in strength, so that when the glass fiber filter materials are processed into folds, the fiber filter materials are easy to be irreversibly damaged under the actions of mechanical shearing, bending and the like, the bonding strength of the filter materials is reduced, the filter precision is continuously attenuated in the whole life cycle, a large amount of pollutants which are adsorbed and intercepted by the filter materials can directly flush to the downstream, and disastrous results are caused to an oil system. Therefore, the traditional pleating process of the glass fiber filter material can greatly reduce the original strength, reduce the stability of the filtering precision and shorten the service life of the filter element.

(3) feeding the pleated filter cake into a pleating machine, and starting a hot air heating device of the pleating machine to carry out hot air heating to 100-150 ℃;
(4) and after the hot air heating device reaches the target temperature value, starting to perform folding operation.
Further, the infrared radiation heating in the step (1) is directional radiation heating of the monocrystalline silicon plate; when the monocrystalline silicon plate is heated by infrared radiation, the distance between the monocrystalline silicon plate and the surface of the filter material is 3-10 cm; the width of the single crystal silicon plate is 30-50 cm; the temperature control precision of infrared radiation heating is +/-2 ℃.
