What do you need to pay attention to when using automatic oil press?
First, check and debug
1. Before the oil pump test, add clean mechanical oil or vegetable oil into the oil tank and press the handle up and down to see whether the piston of the oil pump rises. If the piston is not rising, or there is no pressure in the handle, check the valve in the tank to remove air from the line.
2, for the pressure test of the whole machine, the pressure used in the test is 1.25 times of the working pressure. Check the piston for a large working stroke. The pressure is 15 minutes, the gauge reading should not be more than 4% of the test pressure drop. All oil lines are not leaking; After all the pressure is eliminated, the pressure gauge pointer returns to 0 position. There is no damage to the parts, no obvious deformation of the tie rod, and no stuck moving parts.
3, reliability test on the reliable valve, the reliable valve to the working pressure (upper left 5, lower left 1)MPA, continuous test for 5 times, the needle valve open and close sensitive, each jump valve after the pressure gauge reading should not be lower than the rated working pressure.
Two, maintenance and repair
1, the pressure oil in the oil pump should be filtered, the concentration should not be too large, easy to use rapeseed oil, soybean oil, peanut oil, etc., prohibit the use of gasoline, kerosene and other easy fuels.
2. Keep the tank clean, clean the tank every 3 months or so, replace the new oil, or take out the tank for filtration. The impurities in the oil will wear the oil pump, block the oil circuit, and affect the work of the oil compressor.
3. Lubricating oil is often added to reduce the wear of the connection pin between the handle and the oil pump.
4, screw oil press should be installed indoors, to avoid open wind and rain, resulting in rust and oil pollution.
5. When parking for a long time, the machine should be wiped clean, oiled and covered with a protective cover.
