Sealing Of Mixing Machine
The shaft end seal
The efficiency and service life of the mixer are directly determined by the seal of the shaft end. Automatic shaft head seal lubrication system, improve sealing effect and life. Air pressure shaft head protection device, to ensure the blender work more stable and reliable operation.

How to check whether the lubricating grease really reaches the main shaft head of the automatic shaft head sealing lubrication system.
The method is as follows:
2-1. Check the oil pressure indicator (10--60bar) : if the oil pressure indicator is lower than l0bar, the valve core is blocked; If the gauge indicates higher than 60bar, the shunt core is blocked, the shunt core is blocked.
2-2. Check the grease consumption ( Greater than or equal to 42mL /h). That's 1/4 of the tank per day. If the consumption is lower than this, it is necessary to check whether there is lubricating oil delivered to the four shaft heads. The method is as follows: Each of the four shaft ends is equipped with a spare grease nozzle, and the ball core of the grease nozzle can be pressed with the top of the nail. If there is grease coming out from the ball core, the lubricating oil pump is normal.
2-3. If it is found that the shaft head is short of oil, first check whether the shaft head tubing is unblocked, then check whether the shunt valve is blocked, and finally check whether the pump heart is normally supplied. If the fault cannot be stopped, butter should be added with butter gun at the grease nozzle at the shaft end, not less than 2 times a day.
Pneumatic shaft head protection device
Adjust the pressure reducing valve to 1-1.5bar. Check the pressure of the air pressure solenoid valve after it is energized (0.2-0.5bar). Air pressure solenoid valve gets electricity when feeding. The air pressure solenoid valve loses power during unloading.
Clearance adjustment between liner and blade
Clearance measurement blade and cylinder body highest point, normal working clearance 3-8mm. Blade bolt adjustment torque is 200Nm. After clearance adjustment, the tightness of bolts should be checked again after several cycles of work.
