Fault and troubleshooting method of oil press of oil pressing equipment

The oil press is composed of two parts: hydraulic pressure and press, and its common faults and troubleshooting methods are as follows.

1. The pressure of the hydraulic pump is not enough.

The reasons are: the oil outlet valve has dirt or poor contact; The oil return is caused by poor contact between the screw plug of the inlet and outlet valve on the press and the valve seat or is not tightened; The wear gap between the small piston and the pump body is too large. The corresponding exclusion method is:

After dismantling and washing, it is ground to make it tight; Grind the oil valve plug and valve seat on the grinding press to make it close or tighten the screw plug; Replace the pump with a new one.

2. The hydraulic pump can't pump oil.

The reasons are: the oil filter is blocked; If the oil is used for too long, there is sediment attached to the oil inlet valve, so that the throttle is not sealed; The oil in the tank is too thick or condensed due to weather; insufficient oil in the tank; The hydraulic pump is not vacuumed. The corresponding exclusion method is:

cleaning the oil filter; Replace the oil with new oil or release the old oil; Filter and clean the inlet valve, and grind it to make it fit well; Replace the thin oil, and the room temperature should be increased in cold weather; Fill the tank with a sufficient amount of fuel; Pull out the small piston, inject the oil and press again.

3. The pressure gauge pointer cannot be maintained and declines rapidly.

The reasons are: the safety valve is not sealed; Poor contact between the screw plug of the inlet and outlet oil valve and the steel ball; The oil pipe joints and the hydraulic cylinder screw plug and the oil inlet hole of the hydraulic cylinder are not tightened; The three-way return valve is in poor contact with the steel ball. The corresponding exclusion method is:

Grind the safety valve to make it tight; Grind the inlet and outlet valves to make them tight; tighten the oil pipe joints and hydraulic cylinder plugs; Grind the return valve.

4. The rocker is jacked.

The reason is: poor contact between the oil outlet valve and the steel ball; The spring head is detached from the steel ball. The corresponding elimination methods are: grinding the oil valve and replacing it with a new steel ball; Enlarge the spring head.

5. Local material. Here's why:

The temperature of oil steaming and frying is not suitable, the material temperature is too low, and the water content of the cake blank is too high; uneven thickness of cake blanks; When the bread is loaded, the bread is not stacked properly; Too fast and too strong when pressing. The corresponding elimination method is as follows: take an appropriate direction of steaming and frying, increase the temperature to more than 85, and the water content is less than 7%; Pay attention to the uniform thickness of the cake when making cakes; When the bread is loaded, the cake should be folded right; Reduce the pressing speed appropriately.

6. The oil leaks out from the gap between the hydraulic cylinder and the piston.

The reason is: the leather bowl is wrongly loaded upward; The leather bowl is damaged. The method of exclusion is to reinstall the bowl and replace it with a new one.

7. The safety valve fails.

The reasons are: the oil is not clean, and the dirt settles on the contact surface; The spring loses its elasticity; The adjustment screw is not loosened to the specified pressure; Often overpressure work, the steel ball will hit the valve. The corresponding exclusion method is:

Disassemble and clean, such as valve port and valve pin damage should be grinded; Replace the springs; Re-adjust the screws so that the pressure reaches 40MPa; Re-grind the valve, replace the ball with a new one and take care to operate according to the operating procedures.

Oil extraction equipment includes a tea seed green peeling machine. Automatic oil press, small oil press, screw oil press, hydraulic oil press, whole grain oil extractor, centrifugal oil purifier, plate and frame filtration, closed wok, peanut shelling machine, refining oil equipment hoist and other Jinxin oil extraction equipment provides.

Pls are you in **? You see that your oil press was bought in **, you can contact the factory, tell their maintenance department about the situation, and ask them to come to help you repair it, or move the oil press to their factory to repair.

If it doesn't work, you see what model your oil press is, you can check it on the Internet to see which factory has that model of oil press, and you can go to which factory to see if you can repair it.

If you can't do it, you can find an electrician near your home to help you take a look.

1. Before using the oil press, you must read the instruction manual carefully and be familiar with the performance characteristics and operation methods of the machine.

2. Before starting, a comprehensive inspection must be carried out, the fasteners shall not be loose, the handle shall rotate flexibly, the pulley shall be rotated by hand, the running parts shall be normal, and there shall be no abnormal sound, and then 30 oil shall be added to the reducer.

3. Loosen the lock nut, turn the adjustment screw counterclockwise (the adjustment handle rotates counterclockwise, the cake gap narrows, the adjustment handle rotates clockwise, and the cake gap widens), so that the cone of the screw is pressed against the cone of the cake ring, and then the adjustment screw is screwed clockwise (3-5 turns), and then the nut is tightened and ready to start.

4. The machine is connected to the three-phase four-wire power supply, after the power supply is turned on, the spindle should be rotated counterclockwise, no matter what the situation, the machine must have a good grounding device, otherwise it can not be turned on.

5. Adjust the temperature controller, adjust to the required temperature of 120 -180 (according to the oil), turn on the heating switch to the heating position of the main engine, heat up the machine, then the green light on the temperature controller is on, the red light is off, when the temperature of the machine rises to the set temperature, and the red light is on and the green light is off, the temperature of the machine is automatically controlled and maintained at the set temperature, when the temperature is low in winter, the heating switch is turned on to the whole heating position of the main engine, so that the temperature of the oil pan rises, so that the oil is easy to stay.

6. Press the button of the main motor (turn on the switch of the main engine to the correct position), and the main engine will start to run, and the rotation direction should be counterclockwise.

7. After the installation of the new oil press, 4-8 hours of grinding, the method is to use the cake that has been squeezed dry oil to feed slowly from the hopper, and repeatedly squeeze back to polish the squeezing chamber. If the feeding is too violent, there is an abnormal sound in the pressing chamber or the screw shaft is stuck, it should be stopped immediately to eliminate the obstruction, or reassemble it before starting the grinding, and it is strictly forbidden to forcibly tow the truck.

8. When the oil is pressed normally, the feeding must be kept even, and the material must not be too much or too little or the material is idle. At this time, the load of the machine is normal, the operation is stable, and the sound is rhythmic. The cake is smooth, the low-pressure section is basically no slag, and the high-pressure section has a small amount of oil residue, but the proportion of the slag in the oil is not more than 10%, and the temperature in the squeezing chamber can reach 150-200.

Squeeze out the hot cake and spread it out in time, don't rush to pile or ship, otherwise there will be a natural phenomenon. When the continuous working time is long and the machine temperature is too high, cooling measures such as electric fan blowing should be taken.

9. When the pressed oil flows into the oil filter, press the vacuum pump button, the vacuum pump starts to run, the air in the oil filter is pumped out, the oil filter barrel of the oil press is formed internal pressure, the oil above is naturally pumped into the oil filter, and the oil residue is isolated on the filter cloth, after the pressing is completed, the oil is pumped, open the valve on the oil filter, stop the operation of the vacuum pump, the dry residue is formed on the filter cloth, scrape off with a scraper, and the bottom valve of the pure oil filter in the oil filter can be released.

10. Shutdown. Before stopping, stop feeding, then put in a small amount of cake crumbs, wait for the remaining material in the press chamber to be exhausted, and the cake outlet will no longer produce cake before it can be stopped. After the shutdown, the adjusting screw will be rotated clockwise for 1-3 turns, and the power supply will be disconnected.

Abstract: How to install oil press equipment? How to maintain the oil press equipment?

The correct installation of the oil press can ensure the normal operation of the oil press, and the newly purchased oil press should be thoroughly cleaned before installation. During installation, the pulley of the motor should be aligned with the pulley of the oil press, the position should be moderate, the direction of rotation should be correct, and the tightness of the transmission belt should be adjusted appropriately. The daily maintenance of the oil press is equally important.

Oil press equipment installation] The correct installation steps of the oil press How to maintain the oil press equipment.

Proper installation steps for the oil press.

Before installation, the newly purchased oil press should be thoroughly cleaned. Pull out the spindle, remove the upper pressing cage, and use an abrasive cloth to polish the outer surface and inner surface of the snail and the screw feeder. Grease is added to all lubrication parts, and the variety and grade of lubricating oil added to the gearbox should meet the requirements on the manual.

After the round row is polished and cleaned, it must be arranged according to the original position when it is installed, and it cannot be misplaced, because the arrangement position and order of the round row have a great relationship with the oil extraction performance. After the round row is installed, it is pressed with a compression nut, and the degree of compression is suitable for the disc to be able to live in the oil pressing. After the above treatment, the oil press can be fixed to the foundation with anchor bolts.

When installing the oil press, the pulley of the motor should be aligned with the pulley of the oil press, the position should be moderate, the direction of rotation should be correct, and the tightness of the transmission belt should be adjusted appropriately.

How to maintain the oil press equipment?

1.After every 50 hours of work, the lubrication should be checked, the oil cup on the reducer should not lack oil, and the bearing in the adjusting screw shaft should be filled with butter once per shift from the adjusting screw hole, and dry grinding is strictly prohibited.

2.Each lubricating part should prevent the invasion of dust and other impurities, and the oil quality of the reducer should be checked once a year, and all the oil should be replaced if deterioration is found.

3.When the pressing amount is reduced, and the cake or oil is not properly discharged, the screw shaft should be withdrawn, and the wear and tear of the screw, strip and cake ring should be checked, and the worn parts should be replaced in time.

4.At the end of each shift, the residual cake in the machine should be removed, and the dust and grease on the surface of the machine should be wiped clean.

5.When stored for a long time after the end of the production season, the oil press should be maintained once, and the snails, strips, and cake rings should be dismantled, washed and re-oiled, and placed in a dry place.

Summary. How to solve the fault of cake with oil in the small oil press:

1.In order not to ensure a good oil yield in the process of operation of the oil press, it is necessary to check the cake output of the oil press frequently during the operation process, and control the moisture of the blank neither too high nor too low.

The normal cake should be flaky, smooth on one side and have a lot of hairlines on the other side. If the cake is loose and weak, or the cake is not formed, the color is dark, and it will be broken by hand, which means that the blank material is added too little water; If the cake is soft, large flakes, or the oil foam increases, it means that too much water has been added. Under normal circumstances, there is no slag or very little slag between the round rows, and the slag is discharged at the strip discharge, if the slag is in the form of fine flakes, it means that there is more moisture, and the powder slag indicates that there is less moisture.

In addition, the change of the oil output position can be used to see whether the oil extraction water is appropriate, and when the oil extraction water is too high or too low, the oil output position is moved backward.

2.The oil press adopts the physical pressing method, the physical pressing does not need to be heated, does not add any chemical raw materials, does not need to clear the oil, is easy to operate, has no wearing parts, and has a long service life.

How to solve the fault of cake with oil in the small oil press:

Hello. It's a pleasure to be with you on this topic. I'm putting together the stuff for you. It takes a little time to type. Please be patient. Thank you!

What's the matter with the mouth of the cake and the oil out of the cake.

How to solve the fault of cake with oil in the small oil press: Noise Hui 1In order not to ensure a good oil yield in the process of operation of the oil press, it is necessary to check the cake output of the oil press frequently during the operation process, and control the moisture of the blank neither too high nor too low.

In addition, the change of the oil output position can be seen whether the water is appropriate, when the water is too high or too low, the oil position is moved backward. 2.The oil press adopts the physical pressing method, the physical pressing does not need to be heated, does not add any chemical raw materials, does not need to clear the oil, is easy to operate, has no wearing parts, and has a long service life.

Didn't add any water.

What about people. The cake is the first in the case, all the oil presses will have residual oil in the cake after pressing the raw materials, which is called the residual oil rate, the residual oil rate of different machines is different, and the residual oil is five to six after the regular machine is pressed. This is quite normal, and it is impossible to completely squeeze out all the oil in the raw materials.

Second, if the machine is defective, it is difficult to say that you have bought a fake, and there will be more residual oil. The solution is to increase the number of oil press stages, and now the oil press can reach five or six stages of pressing, and another way is to use leaching equipment to hold the residual oil in the cake to a point. This is the best effect.

1. Connect the power cord of the household oil press with the fuselage, insert the power plug into the power socket, and turn on the power switch on the left side of the fuselage.

2. After the power switch of the household oil press is turned on, the household oil press will start to preheat, and it will take about 7 minutes to preheat the time, at this time, the panel button will continue to flash (press the hot press cold press button to stop the preheating during the preheating process, and it will enter the cold pressing state).

3. After the preheating is completed, the button on the front panel stops flashing, the oil press automatically enters the oil pressing program, and the screw rotates. The oil press key light is on.

4. After the oil extraction indicator light is on, start oil extraction, the motor starts to work, the screw rotates, and the ingredients are put into the feeding funnel. Use an oil cup to connect the squeezed oil and store it.

5. The squeezed oil is connected with an oil cup and imported into a glass bottle for preservation, preferably once a month, which is fresher and more delicious.

6. After squeezing, put in a paper towel to clean the screw. And bring gloves, rotate the plug protective cover, and remove the screw for cleaning.
