With economic development, and constantly improve the living standards of the national press, people from the beginning of the "food and clothing" to "eat nutritious, eat healthy," the new concept. And as one of humanity's major edible nutrients, when people buy it is more rational. Currently, the edible oil market is divided by the production process is divided into two kinds of oil extraction and exploitation of oil. Oil extraction is soaked with a chemical solvent oil, and then extracted from complex processes, commonly known as "salad." This oil refining process nutrients lost sales peanut oil press oil, chemical solvents and toxic residues in peanut oil press, it has been gradually alienated "salad." Totally dependent on oil press machinery purely physical squeeze, without any chemical solvents. This oil is the maximum degree of nutritional ingredients and authentic peanut oil press to join the pure "green, natural, nutrition, health" has gradually become the main living cooking oil, a huge market prospects, who be the first to enter the oil extraction industry, processing of agricultural products who will scrape the pot of gold. Press consists of two parts consisting of hydraulic and pressing machine, it's common faults and troubleshooting methods are as follows. 1, hydraulic pressure is not enough because: ① the oil valve dirt or bad; ② out of the oil on the valve plug and seat pressing machine or tighten the cause poor contact back to the oil; ③ small piston and pump wear gap is too great. Remedy is appropriate: ① be washable after grinding so close together; ② grinding on oil pressing machine valve plug and seat and out the latest peanut oil press to adhesion or tighten the drain plug; ③ replacement pump. 2, hydraulic pumping oil to reason that: ① oil network is blocked; ② oil used for a long time, there is sediment in the inlet valve is attached on the throttle not close together; in the oil tank is too strong or because ③ cold coagulation; ④ tank fuel shortage; ⑤ unpaired vacuum pump. Remedy is appropriate: ① cleaning oil network; ② replace the old oil with new oil or release; filtered and washed into the oil valve and grind them to make good adhesion; ③ replace thin oil, cold weather should improve room temperature; ④ add enough oil to the tank; ⑤ pull out the small piston, and then injected into the fluid pressure.
