BTMA oil press——Leader in oil press machinery industry
Inspection and debugging of automatic oil press
1. Before the oil pump test, add clean mechanical oil or vegetable oil to the oil tank, and press the handle up and down to see if the piston of the automatic 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.
2. Carry out a 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. Press for 15 minutes. The pressure gauge reading must not exceed 4% of the test pressure. There should be no leakage in all oil circuits; after all the pressure is removed, the pressure gauge pointer returns to the “0” position, the parts should not be damaged, the tie rods should not be significantly deformed, and the moving parts should not be stuck.
3. 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, the pressure gauge reading should not be lower than each time the valve is tripped Rated working pressure.
Maintenance and repair of automatic oil press
1. The pressure oil in the oil pump should be filtered, and the concentration should not be too high. It is easy to use rapeseed oil, soybean oil and peanut oil. It is forbidden to use gasoline, kerosene and other flammable fuels.
2. Keep the fuel tank clean. Clean the fuel tank and replace it with new oil every 3 months or so, or take the oil out of the tank and filter it before use. Impurities in the oil will wear the oil pump and cause blockage of the oil circuit, affecting the operation of the oil press.
3. The connecting pin between the handle and the oil pump should be lubricated frequently to reduce wear.
4. The automatic oil press should be installed indoors to avoid wind and rain in the open air, causing rust and cooking oil pollution.
5. When parking for a long time, wipe the machine clean, oil it, and cover it with a protective cover.
