Common problems and solutions for oil presses 1. Sudden stop, the screw shaft is stuck
The comprehensive value of stone carving culture and art is extremely high. Because of its particularity, a considerable part of stone carving is group carving. And it is endowed with soul by sculpture or designer. It reflects the social life and expresses the artist's aesthetic feelings, emotions and ideals. There are mainly garden sculpture, architectural sculpture, sculpture, stone carving handicrafts, and hundreds of products: marble fireplace frame, figure sculpture, relief, abstract sculpture, fountain, flowerpot, Roman column, railing, pavilion, bust, door cover, stone stool, bathtub, animal carving, tombstone, antique sculpture, etc.
1 In the initial stage of pressing, the pressing of the crucible is not caused by a large amount of feeding, and the hot oil seed (which can also be dried with a heated water) can be slowly fed, and the mill is repeatedly milled to raise the temperature.
2 During the pressing process, the squeezing and squeezing materials are cut off, and then a large amount of material is fed, resulting in poor discharge, and the squeezing is caused by oil blockage. Therefore, the feeding should be continuous and uniform, and the cake should not be too thin. In the event of a malfunction, immediately turn off the power, insert the feed adjustment plate, stop feeding, and open the discharge plate, and open the screw shaft to make it exit. Then remove the oil from the crucible and re-press.
3 The oil is not cleaned, and there are hard foreign objects such as stones and metals entering the press.
2. The oil press does not produce oil or the oil yield is too low.
1 The raw material is not wet or too dry, it is damp and mildewed, the seed material is not full, and the impurities are excessive. The oil must be re-selected and the oil moisture is high.
The 2 rows of oil seams are blocked by oil slag or the press bars are too tightly assembled. The tightness of the squeezed strip should be adjusted according to the level of oil content.
3 In the initial stage of the press, the temperature of the press is low, the cake is too thin or too thick, and the parts are worn out, etc., which will cause no oil or low oil output.
3, running too much slag
1 Individual strips are bent or the gap is too large. At this point, the strip can be removed, the gauze of the type A can be polished with gauze or oil stone, and the straight strip can be re-installed, and if necessary, a thin iron sheet is placed to keep the gap in the range of 0.05-0.08 mm.
2 The oil is not plastically good, and it is difficult to make the cake, which increases the pressure of the casing. At this time, the oil should be mixed with water and milled to increase the oil temperature of the oil press to improve the plasticity of the oil.
3 is also too thin. The thickness of the cake should be appropriately increased as required by the instructions.
4, the cake is not smooth
One of the reasons is that the thickness of the cake is not suitable, and the thickness of the cake should be adjusted. The second is that if there are dry cakes or hard foreign objects such as stones and iron blocks entering the machine, it should be stopped immediately, and the oil squeezer should be taken out to check and remove the cake. Dry cakes and sundries in the ring and machine. Repair or replace new parts based on the wear of the cake ring.
5, return oil
It may be caused by the oil seam of the oil press being clogged or the oil seam being too small. The former should remove the strip for cleaning, the latter should adjust the gap between the strips, and polish the seam with oilstone.
6, the oil press does not feed
1 The oil has too much moisture and should be exposed to the sun or dried.
2 The surface of the screw is not light, and the abrasive shaft is sanded with a sand cloth or polished with dry slag. 3 The squeezer of the oil press is worn, the polygon of the squeezer is destroyed, and the presser can be turned over or damaged.
