7.5 Operating procedures

7.5.1 Startup:

a. Before starting, when lubricating with a thin oil station, check if the bearing oil level is normal.

b. Before starting the pump, you must check that the motor is rotating in the correct direction.

c. Before starting the pump, first turn the coupling of the pump by hand to see if the rotation of the rotating part of the pump is flexible. If the bearing is lubricated, it needs to be driven for 5-10 minutes, or 10-20 ml with the upper hole. To make the bearing evenly lubricated.

d. Check all instruments, valves and instruments are normal.

e. Before the pump is started, the pump should be filled with water or the air in the pump should be taken out, and the gate valve (pneumatic control butterfly valve) and pressure gauge cock on the outlet line should be closed, and the sliding bearing circulating water cooling water line should be connected.

f. After the pump is started, open the pressure gauge cock and vacuum gauge cock. And gradually open the gate valve (pneumatic control butterfly valve) on the pump outlet line, and the pressure gauge pointer points to the desired position.

7.5.2 Operation

a. After the pump is running, pay attention to the temperature of the pump bearing. The average temperature rise does not exceed 400C, and the maximum temperature does not exceed 750C.

b. When the pump is running, always pay attention to refueling.

c. The normal leakage level in the packing chamber is subject to 10-20 drops per minute, otherwise the packing gland should be adjusted.

d. Check the coupling regularly.

e. During the operation, if the fault is found, stop it immediately and refer to the troubleshooting table for repair.

7.5.3 Shutdown: Slowly close the gate valve (pneumatic control butterfly valve) on the outlet pipe and the vacuum pump cock on the pressure gauge cock and inlet pipe, and then cut off the motor power.

7.5.4 Do the following equipment lubrication work
