The hydraulic machine must have a hand operation, the host in the process allowed the boost gauge to 55 MPa from the people when the main motor is stopped , otherwise it should immediately turn off the power and check the pressure gauge is damaged, malfunctioning , Briquette machine is damaged, such as damaged should be replaced immediately check and correct before turning to use when the gauge rose to 55 MPa, electrical control system automatically stops when pressed tang when the pressure drops to 45 MPa , electrical control system automatically opens, the pressure gauge rise again , pressing Tang seam no oil leaking out of the oil , said oil has been pressing to do . Determination of the width of the port of discharge if the process does not match the width of the requirements should be donut maker. It must be noted that the determination of peanut oil press when the port of discharge , to be carried out under an empty load. In order to balance the load of each segment reasonable crusher , crushing size requirements to ensure that the product, the crusher must be regularly measured and the port of discharge adjustment , depending on the specific situation , measured and adjusted weekly for 3 to 4 times.
