Hydraulic oil press , Do you know how to operate ? BTMA

As we all know,in  the oil press market,hydraulic oil press covers a large area, consumes less power, and has better oil cake quality.

It is widely used in rural areas in various countries. It is used to squeeze oil from oilseeds such as peanuts, soybeans, sesame, cotton seed and rapeseeds.

Today Benteng oil press will introduce some knowledge about how to use hydraulic oil press.I believe after you have read the article how to use hydraulic  oil press, you can operate it correctly.

hydraulic oil press


1、Inspection and debugging


  • Before the oil pump test, add clean machine oil or vegetable oil to the oil tank, press the handle up and down to see if the piston of the oil press rises. If the piston does not rise or the handle is effortless when pressing, check the valves of the fuel tank and remove the air in the pipeline.


  •  Carry out the pressure test of the whole machine. The pressure used in the test is 1.25 times the working pressure. Check that the piston extends to a large working stroke. The pressure is stabilized for 15 minutes. The pressure gauge reading should not exceed the test pressure. 4%; There should be no leakage in all oil circuits; after all pressure is removed, the pressure gauge pointer returns to the “0” position, the parts should not be damaged, the tie rods must not be significantly deformed, and the moving parts should not be stuck.


  • Carry out reliability test on the safety valve, adjust the safety valve to working pressure (upper left +5, lower left ++1) MPa, test 5 times continuously, the needle valve opens and closes sensitively, and the pressure gauge reads the same after each valve trip It should not be lower than the rated working pressure.


2、Hydraulic oil press Operation


  • According to different oils, master the pressing temperature and water content of the cake.


  • When pressing, lower the top plate to the position, loosen the nut of the movable rod, pull out the two movable pins, and turn the movable rod to one side. After the cake is loaded into the press chamber in turn, turn the movable rod back to the original position and fix it, first pre-press until it sees the oil, return to the piston, and load the remaining cake for formal pressing (generally hydraulic oil press can hold 20 cakes) .


  •   When pressing the handle, press lightly when pressing, and the force must be even, not too strong, otherwise, accidents may occur.


  • Squeeze oils with high oil content (such as peanut kernels, rapeseeds), first use a low-pressure pump when squeezing again, and switch to a high-pressure pump after the oil is discharged.


  •   If it is found that the pointer of the pressure gauge does not return to the zero position during work, it should be checked, repaired or replaced in time.


  •   Open the oil return valve, the oil will automatically flow back to the oil tank, the piston will automatically fall, and the squeezer can be unloaded.


3、Maintenance and repair of Hydraulic oil press


  •  The pressure oil in the oil pump should be filtered, and the concentration should not be too high. Use rapeseed oil, soybean oil, peanut oil, etc., and prohibit the use of gasoline, kerosene and other flammable fuels.


  •   Keep the fuel tank clean, clean the fuel tank and replace it with new oil every 3 months or so, or remove the oil from the tank before use after filtering. Impurities in the oil will wear out the oil pump and block the oil circuit, affecting the operation of the oil press.


  •  The connecting pin between the handle and the oil pump should be lubricated frequently to reduce wear.


  • The hydraulic oil press should be installed indoors to avoid wind and rain in the open air, causing rust and cooking oil pollution.


  • When parking for a long time, wipe the machine, apply oil, and cover with a protective cover.
