SJ900Double Shaft Agitator
Operational Instruction
SJ900 double shaft agitator is new type high effectiveness stirring equiment,suitable to stir the materials with high viscosity.It is pioneer machine in china.
There are high speed shaft and low speed shaft in the machine. Thestirring device in the low speed makes the material to overturn up and down in cylinder.the gear type vanes at high speed shaft bumps to and cuts the overturned materials in cylinder so as that the gathering body is broken quickly,mixed uniformly and solves quickly.
The foreign and domestic advanced frequency changeable speed adjustment device is prepared for this machine.you can slect the best stirring rotation speed according to the material characteristic.

Structure: this machine consists of eight parts: hydraulic lifting, driven box,high & low stirring shafts,. Clamping device, stirring cylinder, hydraulic system, electic control box, frequency changeable speed adjustment device.
Performance:
⑴the vertical shaft lift and falls stably and flexiblity with an overflow protection device,which is safe and reliable with easy operation and good sealing.
⑵In driven box, the low speed shaft is driven by reductor bringing up the main action wheel, which brings up the follower wheel through belt. The high speed shaft is linked with motor directly with smooth, stable and reliable drive and the compact structure.
⑶Main driven sysstem runs stable and smooth with low noise, compiance with the environmental protection standard.
⑷The gear pump is equipped for the hydraulic system with good driving performance in hydraulic system.
⑸The electric control box adopts the new products:CJ20 andCJ10 high quality electrical elements with compast structure, reasonable layout. The insulation resistance is not less than 2MΩ. The frequency changeable speed adjustment device is jointed with control box board as one body,All control buttons are fixed on pallet with easy operation and beautiful appearance.
Installation
⑴There should be pre-moded holes and embedded foot bolts 6-M20╳400(80mm higher than the ground level) for equipment foundation, refer to foundation size drawing for details.
⑵The main machine installing vertical shaft should be vertical to the ground surface.
⑶Oil tankinstallation
The oil tankof this machine has explosion protective function, which can locate at the explosion protective zone.
(Ⅱ)Commissioning
⒈Clean out the oil tank, pour into 32#machinery oil to the 2/3 of oil mark height of upper piastic.
⒉Check the clamping mechanism and cylinder whether they are are clamped tightly.
⒊Check whether the V-belt is tight properly.
⒋Commissioning
⑴Turn on power,press the lifting (pump motor) button, loose the air discharge valve screw,after drain away the air in cylinder, screw it tightly, adjust the overflow valve to the oil pressure 18Kgf/cm2(1.765Mpa).
⑵Press the lifting button to make the cylinder to lift to mix. Stroke,then stop the machine and check the oil position of oil tank is not lower half of plastic oil mark height. Or,supplement the oil.Meanwhile, check whether alllinked part positions and sealing positions haveleakage. Press the falling button(Magnetic slide valve),make the cylinder body falling down to the lowest position.
⑶After the stirring cylinder is alined to middle, adjust the adjustable screw in clamping device.
(I)Use
⑴turn on power, check whether all switches in control box, indicationg lamps button and voltage run well.
⑵Clamp the stirring cylinder,make the clamping stroke closing, turn on the second power source, selec the frequency conversion running or linefrequency running,press the button according to indicating plate. then, you can operate machine.
⑶If the frequency conversion is required to run, please turn on the conversion power when the motor is under stopping conditions, adjust the cycle to the required frequency.
Frequency | 60 | 50 | 40 | 30 | 20 | 10 |
Low speed(r/min) | 144 | 120 | 96 | 72 | 48 | 24 |
⑷During operation, you should always pay attention to current. If the current is overloaded running, please stop machine to check cause, after drain out the fault, the machine can go on to run.
⑸In normal operation or production or commissioning, you should thrust the material firstly, after the low speed vane is immerged into material, you can start the low speed shaft with low speed rotation .Meanwhile, add the same body of material slowly. After finish to add the material, you can adjust the speed to the high speed and start the high speed shaft and return button.
⑹In normal operation , the material cylinder has 0.7 factor for material loading, i.e. The height of material loading is 490mm.
⑺During operation, if the power is cut for too long time, the material temperature falls down to normal temperature and its viscosity is increased. Maybe, due to other cases such as solid content increasing, high viscosity,overload, the machine can,t start, you can lift the stirring vane over the liquid level, then start the low speed shaft with low speed, finally make the vertical shaft falling down slowly (by manual).when the dispersing vane immerges under liquid level, you can start high speed shaft. In thia time, the stirred material temperature rises and the viscosity falls down, it can reach the normal operation target. The operation time can,t be too long, in case the solvent agent is volatilized.
⑻After finsh working and stop to use, please cut down general switch Ⅲ, in case the machine is damaged.
(Ⅱ)Maintenance
⒈Normally add the lubricating oil to all driving parts. For high speed driven shaft, add MOS2-2(2# Lithium base lubricating grease)one time every week. For low speed drinen shaft, add ZL45-2(2# Lithium base lubricating grease), change the grease each half year.
⒉For oil tank, adopt 32# machinery oil, change oil each half year and clean up the oil tank. Each month, clean up the filter screen. After change oil again, clean up one time within two or three days.
⒊for the AC contactor, check one time each half year. After the equipment is used continuously for one year, make an overhaul.
⒋If the equipment is not used for long time,you should cut off the power, clean up the whole manchine, pour all lubricating places. For main shaft and plunger, guide rod, please paint the oil to prevent from rust.
