Use Oil Expeller To Press Oil In A Correct Way

Faults

Reasons

Solutions

Mandrel stops running

① Feed lots of materials before grinding the pressing chamber hot.
② The cakes are too dry when grinds.
③ The cake is too thin and the pressing chamber pressure increases.
④ Solid materials jam the pressing chamber.   

① Feed materials after the oil cake coming out.
② Increase the cake moisture.
③ Adjust the bolt to increase the cake thickness.
④ Switch off the electricity and clean the pressing chamber.

The materials can't be charged in or the oil can't outflow

① The pressing screw is not smooth.
② The pressing chamber has oil in it, the oil material and oil mixes.
③ The oil grooves of pressing strip and pressing ring are jammed.
④ The oil material moisture is too low when choose hot squeezing.

① Grind the pressing screw with oil cakes.
② Squeeze oil materials by adding some cakes. Refeed materials gradually.
③ Take down the pressing strips and rings, soak them for ten minutes with hot water, then clean them.
④ Ensure suitable oil material moisture.

Abnormal cake outlet

① Squeezing-in moisture is too low.
② Squeezing-in moisture is too high.

① Add water.
② Dry the materials.

Locknut exudes oil

① The pressing screw end faces have residues, and there forms gap.
② The locknut doesn't compress the pressing screw tightly.   

① Stop the machine and clean the pressing screw end faces.
② Tighten the locknut.

Locknut exudes oil

① The pressing screw end faces have residues, and there forms gap.
② The locknut doesn't compress the pressing screw tightly.   

① Install the pressing rings correctly.
② Thicken the cake thickness.
③ Change the machine parts, choose pressing strips and rings that fits for pressing high oil content oil materials.
④ Clean the oil groove.

 Low oil yield

① The pressing screw and pressing rings are not smooth.
② Oil materials contain too much moisture.
③ The cake is too thin.
④ The pressing screw is wore down.
⑤ Squeeze too many times.   

① Grind the pressing screw and pressing rings smooth with oil cakes.
② Decrease the oil material moisture.
③ Increase the thickness of cakes.
④ Replace new pressing screw.
⑤ Adopt hot squeezing.

 Residue overflows seriously

① Oil grooves of pressing strip and pressing ring are too deep.
② The cake is too thin and the pressing chamber pressure is too big.
③ The pressing rings were not compressed tightly.
④ Squeeze too many times.
⑤ The machine parts were wore down.
⑥ Oil materials are too dry.   

① Adjust the position of pressing strip and ring.
② Increase the thickness of cakes.
③ Compress the pressing rings tightly.
④ Decrease the squeezing times.
⑤ Change the parts.
⑥ Improve the oil material moisture.

 Pressing cage fractures

① Feed too many raw materials suddenly when the machine starts running.
② Metal object enters the pressing chamber.
③ The oil cake is too dry when the machine does grinding-in.
④ Feed forcibly when the gap between the adjustable cake head and cake-out ring is too small.
⑤ Squeeze too many times and don't add water for the materials.
⑥ Feed abundant materials without clean the residual cakes.   

① You should feed slowly first, then add more materials after the oil cake coming out.
② Choose and clean the raw oi material carefully.
③ Add proper water into the oil cakes.
④ Increase the gap.
⑤ Add some water into the materials to low the pressing chamber pressure.
⑥ Start the machine after cleaning the residual cakes.

 Pressing cage fractures

① Reverse the mandrel forcibly when the mandrel locks.
② Reverse the big v-belt pulley forcibly when the mandrel locks.

① It is strictly prohibited to reverse the mandrel.
② It is prohibited to reverse the big v-belt pulley.

 Mandrel breaks off

① The bearing elastic ring is reversed.
② Overwind the nut and lead to crush the bearing.   

① Install the elastic ring correctly.
② There should be certain gap between end faces of nut and bearing.
