1: Firstly, start the lubricating oil pumps and hydraulic stations of the internal mixer, and check whether the oil supply to each part is normal. After the oil pump and hydraulic station have been working normally for 15 minutes, start the main motor and observe whether the rotor direction is correct from the outlet end of the mixing chamber. Usually, before leaving the factory, the internal mixer is air operated for more than 2 hours and then air operated at the user's location for more than 4 hours.
2: Open the cooling water system of the mixer and check for leaks.
3: In both manual and automatic operation modes, the pressure weight, feeding door, and unloading door should be opened multiple times with flexible and reliable movements.
4: During the idle operation test of the internal mixer, check the following items:
a: The lubrication points of the gearbox transmission gears and bearings are fully lubricated, and the sealing parts are well sealed.
b: There should be no significant vibration or periodic noise during operation.
c: When operating in idle mode, the main motor is single speed, and its power consumption should be less than 15% of the rated power
d: There should be no sudden temperature rise in the bearings of various parts of the mixer, and the temperature rise of the rotor bearings and reducer bearings should be ≤ 20 ℃.
