Maintenance and inspection of vacuum oiling equipment

The machining accuracy of the joint surfaces of the sealed vacuum box and the parts connected with the vacuum box should be guaranteed firstly, so that the joint surfaces are in good contact. When assembled, the joint surface is coated with a vacuum sealant, and then tighten all the bolts evenly.

The sealing of lubricating device for each lubricating hole (especially the sealing of butter nozzle when lubricating with grease) is often neglected in the design and application. The internal structure of the butter nozzle is a pressure spring against a steel ball to seal the oil injection hole. When oil is injected, the pressure of the oil gun acts on the steel ball, forcing the spring to compress and open the oil injection hole, and the grease enters the lubricating part. Similarly, when the vacuum suction acts on the steel ball, it forces the spring to compress, allowing air to enter the bearing seat.

Maintenance and inspection of vacuum oiling equipment

1. During the drying process, operators are required. Min check the drying condition and make relevant records.

2, vacuum meters and thermometers should be checked regularly. Regular inspection of the rotation of the moving parts is flexible enough to find problems should be timely parking repair, not forced to use.

3, cylindrical worm reducer (or CVT) should be maintained according to its instructions.

5, the filter in the tank is dried once, that is, to remove the surrounding powder and make the filter unblocked.

6, chain drive chain, at least once a month.

7. Rotary bearing sealing ring (made of fluororubber) is used between vacuum tube and main engine. When air leakage is found, it should be replaced immediately.

1. After receiving the drying notice, start the vacuum pump, open the vacuum pump valve of the dryer, close the vent valve to check whether the vacuum of the dryer meets the requirements.

2. Start the power supply of the dryer and rotate the button of the speed regulator to make the drum of the dryer rotate slowly. Turn the feeding drum manhole of the dryer to the top of the drying table and stop turning.

3. Feeding mode

3.1 vacuum pumping

The inlet of the dryer is connected with the feeding pipe, and the feeding pipe is vacuum pumped. After the wet material is pumped out, the feeding pipe is unloaded and the feeding valve is closed.

3.2 directly from the dryer drum manhole cover feed.

Close the vacuum valve of the dryer drum, open the empty valve, open the empty valve slowly, and put the pressure inside the drum at normal pressure, close the empty valve. Open Kong Gai, put the dry material into the drum. After entering the material, cover Kong Gai and tighten the screws.
