1 Functions and features
Gear reducer mud agitator is one new-type efficient, energy-saving agitator for drilling mud fluid mixing and other solid-fluid mixing. It has small profile, steady running, easy field installation, efficient mixing, good mixing result and high standby power. So it is suitable for high density mud. Energy can be saved by selecting right power of different agitators according to the mud condition and tank dimensions.

3 Installation and Use
3.1 Cut a holeφ200mm on vane axle where install the agitator, place agitator and weld 8# channel steel on its base with tank surface, then unscrew the foot screw, lift reducer, and take vane axle from tank, connect vane axle with reducer output axle with screws, at last connect reducer and base with screws.
3.2 Add the extreme-pressure gear oil 130-160EP into reducer to the standard position (oillet).
3.3 Test running with electricity until getting stable running without noise and correct rotating direction.
4 Notes:
4.1 Add the extreme-pressure gear oil 130-160EP into reducer to the stated position and lubricate in accordance with dipstick. Replace lube every 8000 hours.
4.2 The connecting screws should not be loose. Check screws after running for certain period and tighten the loose screws.
4.3 In transport and installation, protect vane axle from affecting use caused by knocking and deforming.
4.4 The vane axle rotating direction: clockwise from top.
4.5 The tank surface board should be strong enough to prevent agitator from effecting reducer running normally and service life caused by shaking.
4.6 Uninstall the vane axle or install an auxiliary support of vane axle in moving agitator and tank as a whole.
4.7 Wash the mud accumulation away around vane axle with mud gun to prevent from the motor burn out result from too big start up load before restart agitator.
5 Disassemble and maintain reducer (11kw, 15kw)

5.2 Disassemble and change instruction
5.2.1 Screw off oil plug of reducer，drain all the lube in the body.
5.2.2 Unscrew the bolts connecting reducer and motor, and the bolt 33 fixed back cover 9. Then disassemble reducer and its back cover, look at the inside structure and clean the broken asbestos paper.
5.2.3 Disassemble the output shaft: Unscrew 34, 35 bolts, remove the output flange 10 and steel cover 32 on the output shaft, and retaining ring 19 and gasket 13. Then fill up the reducer with shaft 7 adown. Fill wood block between the big gear and reducer body, remove the output shaft at steel cover 32, and install new bearing to replace the old one.
If only to change the disabled oil seal, do following this: disassemble the output flange, remove the disabled oil seal, and review hole surface there and seal packing of fitting surface. If there is no breakage, fix the output flange to the old place, screw up the bolts after cleaning the glue.
If the output shaft at the place of oil seal has scar, make good with fine sand paper to avoid oil leaking. When oil seal is passing the output shaft, fill up plastic underlay to protect the lip. Take out the underlay after oil seal placed. Adjust the seal and flange hole for face to face, knock around it into the hole lightly with a small hammer.
5.2.4 Disassemble the third class gear shaft: screw off the bolt 36, take down the second steel cover 14, get the sprag17 for hole and spacer 12, then fill up a wood block, extrude the third class gear shaft with hydraulic machine.
5.2.5 Disassemble the spiral bevel gear: make the reducer vertical with import department upwards, put down a mat to avoid breaking the falling bevel gear shaft 3. Take out the sprag16 for shaft and spacer 11, knock it out lightly with a small hammer. Then the disassemble of reducer has finished.
