Detailed Product Description: | Hot water lubricated high vacuum panel Zhejiang water lubricated high vacuum panel Xingtai Crystal Johnson both ends of the vacuum box to adjust the width of the absorbent device, usually a baffle and water seal to prevent air leakage into the vacuum tank. Between the baffle width is adjusted according to the width of the papermaking wet paper with a screw. In the transmission side of the vacuum tank has a suction port, connected with a vacuum system used as a drain. Has a water inlet at one end of the operating side, the use of the vacuum tank for washing. Usually the breadth of the vacuum tank of 200 to 300 mm, from 250 to 300 mm for the general use of a paper machine. Vacuum box: dehydration mechanism of the dewatering mechanism of the vacuum box, on the one hand is due to compression of the sheet up and down the pressure difference sheet dewatering, on the other hand, internal voids due to air flow through the sheet when the water into the vacuum on the fiber box. In the general case, the waterline before the vacuum box known as a wet box (note, not wet vacuum boxes), the sheet dewatering in several vacuum oven, mainly due to sheet the upper and lower pressure difference sheet compression and dehydration; water the vacuum oven after the line is called the dry box, on several vacuum suction tank, the sheet dewatering is mainly due to the air flow passing through the internal voids of the sheet, the fibers attached to the water into the vacuum box. Waterline is the first vacuum box in a papermaking machine, due to the high moisture content in the wet paper sheet (in the general case, the degree of dryness of the wet paper sheet is less than 7%), the fibers are still suspended in water, its surface is flat liquid surface of the light reflection, the liquid surface such as a mirror: when the further dewatering, i.e. fibers exposed surface of the liquid, light scattering, the mirror disappears, the dividing line between the two is called the "waterline". Under normal circumstances, the waterline when wet sheet dry about 7% ideal waterline should be straight or nearly straight, If the waterline tongue ran, said headbox jet a paper material is unstable. Ran, there are differences in the sheet banner declared. Position from the waterline, it is also possible to determine the net dehydration, the waterline has long been the rapid dehydration; Conversely slow dehydration. |
