NDJ-Viscometer operating instruction
NDJ-1 Viscometer USES:
NDJ - 1 viscosity meter is used to measure liquid viscosity resistance and absolute viscosity liquid new instrument. NDJ - 1 viscometer are widely used in measurement of oil, grease, paint, food, medicine, adhesive and all kinds of fluid viscosity.
NDJ - 1 viscometer structure principle:
1. Use the gear system and clutch for variable speed, the special rotating knob operation, in four gear speed. It need to chose them according to measurement.
2. Different specifications according to the instrument with 0 to 4 five kinds of rotor. It can be chose by the measured liquid viscosity with the high and low speed with selection.
3. Fixed control mechanism of Special pointer for accurate reading use. When speed faster (30 RPM, 60 r/min) not in rotation in reading, then press the pointer control rod, to make pointer fixed down for easy reading.
4. Protect stand is to maintain measurement of stability and protection of the rotor. Use protection stand were determined to get a stable measurement results. Yellow guard circle is protect the instrument coupling part from external attack by the influence instrument accuracy stability.
5. The instrument is portable and it will be equip with the fixed support and elevating, usually it use for small quantity and constant temperature measurement in the laboratory
NDJ - 1 rotary viscometer installation:
1. It need to take out the storage box, holder and 3 adjusting screw from the packing box.
2. Screw three adjusting screw in support of holder.
3. Check the flexibility and self-locking of lifting clamp, to find weather it too loose or too tight, then worker can use phillips screw driver to adjust screw tightly, make its can lift up and down, usually slightly tight is advisable, in case of automatic falling after install the viscometer.
4. Open storage box, take out viscometer, install viscometer to the lifting clamp head, to fix screw by handle (should try to keep it balance), take out the rubber band of indicating joystick, remove yellow guard circle on the bottom of viscometer, and then remove the protection frame from deposit box spin it in the viscometer.
5. Use screw to adjust level of bubble, keep viscosity meter level.
NDJ - 1 type rotary viscometer operation:
1. Prepare measured liquid, in diameter not less than 70 mm in height and not less than 130 m m beaker or straight cylindrical container, the accurate control of temperature of the liquid to be measured.
2. Will protect palletized in instrument (to the right hand into the mount, turn the left off).
3. Will matching good rotor screwing in shaft connecting rod (left screwing in mount to right hand out off). Rotary lifting knob, make the instrument slowly down, rotor gradually immersed measured liquid, until the rotor surface marks and liquid surface flat so far, and fine adjustment level. Switch on the power, press the pointer control lever, open motor, rotation speed knob, make its in selecting good speed gear, relax pointer control lever, wait for pointer stability may be reading, generally need to about 30 seconds. When the speed in the "6" or "12" file operation, stable pointer can direct reading; When the speed in the "30" or "sixty" file, stay pointer stability after press pointer control lever, pointer turn to display in the window, shut off the power for reading. Note: according to the pointer control lever, not too much force. Can be in idle when to practice.
