Key points of operation and maintenance of cement paste mixer in highway engineering laboratory?

What are the key points of operation and maintenance of cement paste mixer in highway engineering laboratory? The following Zhong Da consults the bidding teacher to answer your questions for your reference.

1, automatic: first turn off all three-position switches (1K, 2K), then turn on the programmable input socket on the plug panel of the time controller, and then turn on the power supply.

2. Turn the 1K switch to the automatic position, that is, slow stirring is completed 120 seconds, alarm for 5 seconds after stopping 10 seconds, and stop automatically after fast stirring 15 seconds.

3. Repeat the above operation and execute the next automatic operation procedure.

4. Manual: set the 1K switch to manual position, and then set the 3-position switch 2K to slow, stop, fast and stop, so as to complete each action and manually time.

5. After the cement is put into the pot, move the handle, and then tighten the positioning screw to stir. Dismantling the stirring pot is the opposite.

Maintenance of mixer:

1. Keep the workplace clean. After each use, thoroughly remove the residual slurry inside and outside the mixing blade and the mixing pot, and clean up the mortar and stolen goods scattered and flying on the machine.

2. There is no oil injection hole outside the pulp mixer. The worm gear pair, gear pair, bearing and other moving parts in the gearbox are added with molybdenum disulfide grease once a quarter, and the bearing cover can be opened separately when refueling. Always drop oil between the sliding plate and the column guide rail and between the surfaces of relatively moving parts for lubrication. All machines should be cleaned once a year and filled with lubricant.

3. When the machine is running, in case of metal crash, first check whether the gap between the stirring blade and the stirring pot is correct.

4. When using the stirring pot, handle it with care, and don't knock against it at will to prevent the pot from deforming.
