AFS Foundry Sand Testing Equipment Operating Instructions Manual

RIDSDALE-DIETERTMETHYLENE BLUE CLAY TESTER AND ULTRASONIC ACCESSORY (cont’d)IIDESCRIPTION (cont’d)The heavy metal base is designed to accommodate in as compact an area as possible theself-filling burette system, stainless steel beakers and motor stirrer unit. The ancillaryequipment, such as repeating pipettor, tetrasodium pyrophosphate, methylene blue solution,filter papers, glass rod, vaseline and Allen wrench, and the Ultrasonic Accessory, completesthe list of items required to determine the live clay in a foundry sand system.IIIINSTALLATION(a)(b)(c)(d)(e)(f)(g)(h)(i)Drop the reduced end of the post into the hole in the base until the bottom of the postis flush with the bottom of the support collar. Tighten set screw with Allen wrenchprovided.Attach one clamp holder to the post, allowing approximately 8” (200 mm) from thebase to top of the clamp. Attach clamp so that the thumbscrew points to the front ofthe base. (Refer to Fig. (i) for proper placement of all clamps).Attach one burette clamp to the post, approximately 2” (50 mm) from the top of thefirst clamp. Attach clamp so that the portion of the clamp which holds the burettepoints to the front of the base.Attach the other clamp holder to the post, approximately 3” (75 mm) from the top ofthe second clamp. Attach clamp so that the thumbscrew points to the front of thebase.Attach the second burette clamp to the post, approximately 15” (375 mm) from thetop of the third clamp. Attach clamp so that the portion of the clamp which holds theburette points to the front of the base.Attach the extension clamp to the post approximately 5” (125 mm) from the top of thefourth clamp. Attach the clamp so that the thumbscrew points to the front of thebase, then check to ensure all the clamps lie on the same vertical line with the base.This will allow the burette to be positioned vertical and reasonably level. Position thesolution bottle holder.Attach the cup holder to the bottom clamp holder. Attach the cup holder so that itprojects approximately 6” (150 mm) to the right of the post.Attach the agitator shaft to the motor and lock the nut on the coupling.Attach the motor mounting shaft to the middle clamp. Note that, for proper alignmentbetween the agitator and beaker, the stainless steel beaker should be placed in thecup holder. Slide the motor mounting shaft in the clamp until the agitator disc iscentred inside the stainless steel beaker. Lock the back thumbscrew on the clamponce the proper position is found. (The clamp holding agitator motor will have to beraised and lowered to allow placement and removal of beaker).When the clamps which hold the agitator motor and the cup holder are properlyaligned the distance between the agitator disc and the bottom of the stainless steelbeaker should be approximately 0.2” (5 mm).6
