We produce and supply spare parts for various popular oil presses on the market. It mainly includes 6YL, ZX and YZYX series. The key standard for oil press parts is hardness (HRC), the harder the press ring and worm, the better the wear resistance, so its service life will also be longer than the average life.
Our exclusive hardness is between 61-67HRC, the only secret is the tempering process. Our secondary tempering stamping parts are unmatched in the market for their superior performance.
If you are interested, please feel free to visit our factory and inspect the oil press parts in person!
Maintenance and Assembly/disassembly of Main parts
1 Assembly/disassembly of Main parts
1.1 Pressing cage (round plates, square rods holder)
Rotate the screw shaft and remove it from the chamber. Loose the lock nut on the outlet end by rotating it counter-clock wise using a 24 mm diameter bar, loose four M14bolts, remove ten M16 bolts which are used to connect upper and lower cases. However, after removing upper case, round plates and square rods holder can be pulled out.
1.2 Remove square rods:
After removing the holder, tap the end of one rod and take it out, then others will be easily removed.
1.3 Assembly of rods:
Erect the rod holder vertically and make its side with oil grooves locate downwards, better on a wooden plate, then put square rods to touch holders inner wall circumferentially with their grooves downwards again. However, grooves of every two adjacent rods should not be touched. Then insert shins (by a hammer) properly into rods gap to let than firmly touch rods holders inner wall. As a matter of fact, whole inner wall of rods should be smooth.
1.4 Assembly of the cage:
Put the groove side of rod the holder to face the machine body, and then insert round plates as per marks on them. Put lock nuts on to contact plates and then mount the upper case. Tighten bolts one by one.
Disassembly of the screw:
Rotate the handle as soon as machine stops and pull out the serew from thechamber, remove nuts and adjusting bolt.Insert a 16mm diameter bar into lock nut and turn it into clockwise.(important note:left hand screw).After taking off lock nut,each pait of pressing screw can be removed.However,holes in the screw might be blocked by fine slag particles,which retard the disassembly.Tapping or heatingpressing screw might help disassembling.
Mounting pressing screw:
Put small end of its shaft upwards,mount the first screw and then the second···sequence, tighten then by the lock nut to avoid particles in.On both ends of adjusting bolt, which isthese two bearings touch adjusting bolts double ends. Finally, whole pressing screw will be tightened by twoM42X2 nuts, But certainly, gaps of two bearings need to be carefully set. In fact, if hands can swing adjustingM42X2 nuts, But certainly, gaps of two bearings need to be carefully set. In fact, if hands can swing adjusting.
Machine Operation:
1 preparations before operating
1.1 12kg of lubricant needs to be filled into the gearbox.
1.2 After installing the machine, check whether lubricant has been filled in, bolts have been tightened, and handles are operable.
1.3 Check large pulley whether it is loose or blocked, repair it if necessary.
1.4 Adjust the tightness of the belt, switch on the motor and check its rotation direction.
1.5 Loosen the lock nut and tighten the screw to its end, then loose it for3-4circles and then tighten it again for half circle to assure the gap of the residue cake outlet.
2 Operating
2.1 Feeding must be steady and slow at the beginning to avoid blocking
2.2 In the case no cake is extrude outward,return back the screw for 1-2circle .If there is still no cake is observed,machine needs to be shut down and checked ,However, in any case, operating the machine backward is absolutely prohibited normally ,cake looks like tile but not sticky ;thickness is 1-2mm ,inner side is smooth ,out side creases and no oil the surface is allowed.
Cake thickness adjustment: Rotating the adjusting handle clockwise will make the cake thicker, otherwise will make it thinner. Each circle of adjustment (by adjustment bolt left hand T 165x6)will change the thickness 0.4-0.5mm.
2.3 When machine is operating, oil extruding and residue outlet need be checked
Frequently .Normally, most of oil will flow outward from square rods and several front round plates. Broken cake residue indicates the material is too dry; steam emerging from the cake residue indicates that it is too wet; In any case, water content in the raw material must be adjusted from time to time.
Slag slice emerging indicates too much water content and power-like slag low water content .Loose round plates will cause too much slag flowing outwards. However, adequate water content will cause slag flowing outwards from square rods; little slag from round plates is allowed. In a word, water content affects oil output rate, it needs adjusting properly.
3 stopping
3.1 Repeatedly move screw forwards and backwards for several times and let all material resided in the chamber goes out and adjust the cake to the possible thinnest, then stop the machine.
3.2 When machine stops caused by any accident, power supply must be shut down first, then rotate large pulley manually backwards, let the material return out. Then pull out the shaft and clean it. In the case the shaft could not be pulled out, remove the upper case and loose lock nut, separate round plates and clean them one by one.

Safety:
Following items are strictly requested to be obeyed.
1 During operating, hands or metal rods are strictly prohibited to enter the hopper to touch cakes.
2 Tightening the screw shaft to its dead end is prohibited before starting or during operating, which might cause slag outlet to contact cake outlet ring, resulting in wearing.
In the case of storage, oil dirt on machines surface and slags on each part need to be taken off.
Paint rust-resisting grease and keep in dry place.
Case needs to be covered to prevent dirty foreign particles from entering.
1.Low investment 2.Small workspace
3.Long life usage 4.Easy to install
5.Low labor cost 6.Easy to operate
7.Higher output 8.Can process multiple oil seeds
