Vacuum rake dryer operation procedures

Vacuum rake dryer under normal circumstances, the vacuum pump work should be done after 2000 hours, check Jue rubber seal aging degree, check whether the exhaust valve slice is craze, clean up the precipitation in the dirt from the valve and exhaust valve seat. To clean the whole vacuum pump cavity parts, such as rotor, vane, spring, etc. General clean with gasoline, and dry. The rubber pieces wipe with dry cloth after cleaning. Cleaning assembly to should take put down gently to be careful when bruised. Vacuum rake dryer oil change period according to the actual conditions of use and can meet the performance requirements, and so on and so forth, by the user's discretion. Generally the new vacuum pump, pumping clean and dry gas, it is recommended to work 100 hours in oil at a time. After being oil can't see the black metal powder, can be appropriately extended after oil change period. Repackaging should be done after commissioning, which generally idle running 2 hours and oil change two times, because when cleaning in the vacuum pump will have a certain amount of volatile matter, after being properly functioning, back into work. Vacuum rake dryer to join bearing the body bearing lubrication oil, should observe the oil level in oil mark the centerline, lubricating oil should be timely replacement or supplement.
A. open vacuum pump inspection, pipe joints, whether leak on stuffing box, in and out of the mouth seal are in good condition, vacuum gauge response is sensitive.
B. open cooling water valve check heating pipe joint, whether leak on stuffing box, whether the response of pressure sensitivity.
C. check each meter of the electric control cabinet, button, indicator light is normal, check whether the earth wire is good, with or without leakage, short circuit phenomenon.
D. vacuum rake dryer in the oil cup filled with grease, starting motor run idle, listen to the noise is normal, if abnormal, should check out the source of the noise, and ruled out.
2, will join the container need to dry the material (powder, small granular, slurry material by vacuum feed) and then shut down the feed hole cover.
After 3, close vacuum valve, vacuum pump, make the dry container is negative pressure (600 ~ 755 MMHG).
4, vacuum rake dryer on the power switch, start the motor, work button, start rotating drying machine.
5, open the valve of heating medium, heating medium into the dry container interlayer, according to the requirements of process inspection measurement.
6, dry material is completed, shut off valve of heating medium, then to infuse water interlayer and after being cooled to room temperature of material, to stop pumping air into vacuum state, open the vacuum valve, close the motor, stop rotating drying, open the hole cover discharging.
