Vacuum filter installation, use and maintenance


After unpacking the equipment, remove the packaging grease and check whether the fasteners, instruments, switches and connectors are loose or fallen off.

After the equipment is unpacked, remove the packing grease and check whether the fasteners, meters, switches and terminals are loose or come off.

Power on and ground protection.

Open the valve of the water filling pipeline, continuously supply the vacuum pump with an appropriate amount of supplementary water, so that the pump ensures the formation of the water ring required for vacuuming, and can achieve the purpose of cooling. In order to ensure the performance and operation of the pump, each running time should not exceed 10min. If it is necessary to reuse, the circulating water must be replaced to ensure that the water temperature does not exceed 30°C. (Note: the amount of water added is too small, the water ring cannot be formed, and the calibrated vacuum cannot be reached; If the amount of water is too large, it will increase the water consumption and the power consumption of the motor, and make a harsh noise).

Before driving, open the large and small filter disc valves, and close the rest.

Test start, if there is a scream, you should immediately adjust the water replenishment, until there is no scream, close the open filter disc valve, observe the vacuum gauge pointer, and after reaching the calibration value, the machine can be used normally.

When using a fixed filter plate to filter materials, the filter disc should be locked first, and the filter cloth and filter paper placed on the filter plate should be wet with a small amount of water, and then the slurry should be poured into the filter disc, and the valve of the filter disc used should be opened, which can be repeatedly interrupted or continuously normalized.

In order to prevent the return water from entering the vacuum system during shutdown, the valve should be closed first and the pump should be stopped. After the end of the work, if it is not used temporarily within 1-2 days, the screw plug in the lower part of the pump cover must be opened, the water in the pump must be cleaned, and then stopped. When using, the screw plug must be tightened.

After a long period of shutdown, before starting again, the motor protective cover should be removed, and the motor fan blade should be rotated by hand to make it flexibly rotate before starting.
