Failure |
Reasons |
Fix methods |
Spiral shaft stops rotating suddenly |
①Feeding oil plants before heating the press chest. ②The cake for wearing the machine is too dry. ③The cake is too thin and pressure in the chest is too high. ④Oil plants have shells or hard sundries mixed into the oil plants. |
①Start to feed until cakes come out. ②Increase the cake's moisture. ③Turn the adjusting bolt clock-wise to enlarge the cake's thickness. ④Husk the oil plants. Screen and clean the oil plants. |
Feeding blocked. No oil comes out. |
①The work-sections of squeeze loops and squeeze spirals are coarse. ②Oil plants in the press chest mixed with oil. ③Gaps between the squeeze bars and oil grooves on the squeeze loops are blocked. ④Oil plants have high oil content, need more oil channels to discharge the oil. ⑤Oil plants are too dry when pressing in a hot way. |
①Gradually squeeze the cake (except tea seed) mixed with 10% water until squeeze loops and squeeze spirals' work sections become smooth. ②Add small quantity oil residue cake into oil plants to squeeze together. Slowly add the feeding quantity. Can't suddenly feed too much. ③Dismantle the squeeze bars and squeeze loops. Put them into hot water for 10 minutes and then clean them with wire brush. ④Change to press bars and loops with deeper oil grooves. ⑤Insure the right moisture of oil plants. |
Cake's situation abnormal |
①Moisture too low ②Moisture too high |
①Increase the moisture. Shorten frying time. ②Reduce the moisture. Lengthen frying time. |
Oil belcher from lockout |
①Residue appears between the squeeze spirals' sections and forms gaps. ②Lock nut is loosen. |
①Shut down the machine. Dismantle and clean the squeeze spirals' sections. ②Fasten the lock nut. |
Low oil output |
①Oil plants with low oil content or many impurities. ②Temperature and moisture are abnormal. ③Low temperature in squeeze chest. ④Spare parts frayed. |
①Screen and clean the oil plants. ②Adjust the frying temperature and moisture. ③Follow this instruction to increase the temperature of squeeze chest by wearing the machine. ④Change the spare parts. |
Hasoilcome out from thedeceleration plate or feeding part (return oil) |
①Squeeze bars installed in opposite direction. ②Squeeze bar and loop's oil grooves are shallow. ③Cake is too thin. ④High oil contains, oil can't be discharged in time. ⑤Oil grooves blocked. |
①Install the squeeze bar correctly. ②Set the squeeze loop with deep grooves before the 5# loop. ③Enlarge the space for the cake out, increase the thickness of cakes. ④Change the spare parts, choose right squeeze loops and bars suitable for oil plants with high oil content. ⑤ Clean the oil grooves. |
Residue cake has oil mark on the surface |
①High moisture in oil plants. ②Low temperature of squeeze chest. ③Squeeze spirals and loops not smooth. Feeding not smooth. ④Oil grooves blocked, oil can't be discharged in time ⑤Spare parts frayed. |
①Dry the oil plants, lower the moisture. ②Warm the press chest byrunning-in the machine with cake. ③Press residue mixed with water to polish the squeeze loops and spirals. ④Clean the oilgrooves. ⑤Change the spare parts. |
Low processing capacity |
①Roughsqueezespirals and loops. ②High moisture in oil plants. ③Cake is too thin. ④Squeezespirals frayed. ⑤Oil plants squeezed more than 1 time. |
①Press residue mixed with water to polish the squeeze loops and spirals. ②Dry the oil plants, lower the moisture. ③Increase cake's thickness. ④Change to new squeeze spirals. ⑤Use hot way to squeeze one time. |
Much residue comes from the squeeze loops |
①Squeeze loop and squeeze spiral's grooves are too deep. ②Cake is too thin; Pressure in squeeze chest is too big. ③Squeeze loops are loosen. ④ Oil plants has been squeezed more than 1 time. ⑤Spare parts frayed. ⑥Oil plants is too dry. |
①Adjust the positions of squeeze bars and squeeze loops. ②Increase cake’s thickness. ③Fasten the squeeze loop. ④Reduce squeezing time. ⑤ Change spare parts. ⑥Increase the moisture. |
Press cages breaks |
①Feed too much at the beginning. ②Metal sundries went into the squeeze chest. ③Residue cake is too dry when wearing the machine. ④Space between cake adjuster and the loop is too narrow. Or feeding forcedly. ⑤Oil plants has been squeezed more than 1 time and did not add water into the oil plants. ⑥Begin to feed and squeeze before cleaning the residue in the squeeze chest. |
①Feeding slowly. Add feeding quantity only when the feeding becomes smooth and the cake comes out normally. ②Select and clean the oil plants carefully. ③Maintain theresidue cake forrunning in the machine with reasonable moisture. ④Enlarge the space for the cake out. ⑤Increase oil plants's moisture to lower the pressure in the press chest. ⑥Clean the squeeze chest before starting the machine again. |
Frame damages |
①Reverse the spiral shaft forcedly when it is stuck. ②Reverse the triangle belt forcedly when the spiral shaft stuck. |
①No reversing the spiral shaft. ②No reversing the big v-belt pulley forcedly. |
Spiral axes break off |
①The thrust bearing close to the lock nut has been installed oppositely. ②The hexagonal nut is too tight and pressed the bearing. |
①Install the thrust bearing correctly. ②Need appropriate space between the nut's end surface and bearing's end surface. |
