After the assembly of 300T Forging Press is completed, the test run test is carried out : no-load operation for 30 minutes, test the slider lifting speed ( 0.5-1m / min adjustable ), noise value ( ≤ 85dB ) ; during the loading test, it is gradually pressurized to 300 T rated pressure, and the deformation of the fuselage ( ≤ 0.2mm ) and the sealing of the hydraulic system are observed. After passing the test, it can be put into use.
