LUBRICATION SCHEDULE

The lubrication schedule is mainly required for the rotating parts of the Caustic Pumps and Blowers. The Caustic Pumps and Blowers are required to be lubricated once in three months time. Caustic Pumps shall be replenished with oil as per SAE – 30 or equivalent.

Meggar test the motor and check for direction of rotation.

Check for foreign material inside the Blower.

Check the Impeller and remove any material formed on the blades.

Rotate the Impeller by hand and see whether it is rotating freely without any friction of the sides.

When the direction etc. are checked, start the Blower.


GENERAL WRITE- UP OF CHLORINE GAS ABSORPTION SYSTEM FOR TONNERS / CYLINDERS
IN THE CHLORINATION ROOM

CHLORINE GAS ABSORPTION CAPACITY = 1000 KG/HR (For Tonner)

CHLORINE GAS ABSORPTION CAPACITY = 100 KG/HR (For Cylinder)

LEAKED CHLORINE ABSORPTION SYSTEM

The system is designed to absorb leakage of chlorine leaking from one filled Toner / Cylinder in one hour time. The system is designed to absorb the chlorine gas and not liquid chlorine leaked from the Toner / Cylinder. To stop the leakage of liquid chlorine from toner is the difficult task as the liquid chlorine expands as soon as it enters into the atmosphere. Normally as soon as you find the liquid chlorine is leaking from the valve or body of the toner, you must rotate the toner in 180 degree to convert the liquid chlorine leakage into gas chlorine leakage. The chances is very less for leakage of liquid chlorine from cylinders because it is always used in vertical position.
