Normal water supply oxygen pump start-up, maintenance and service work

A, water supply oxygen pump start

1, the start of dilute oil station 1)

Open pump exit door, start the oil pump, check the pump work normally, the pump outlet pressure should be greater than zero. Before 15 pa, feed water pump bearing pressure of 0. 08 - 0. 15 mpa, the oil temperature 30 ℃ above, the bearing oil flow and the normal oil level 2)

Another pump test, after the normal input interlocking,

3) According to the oil temperature in the heating or cooling device, to maintain the oil temperature at 35 - 45 ℃

2 feed water water pump, start the deoxidization

1) Start the water supply oxygen pump, adjust the recirculation door, feed water pump pressure at 14 - to maintain Between 15 pa, After initial start-up and motor repair should be paid attention to the start of the motor. )

      2) Check the motor current, discharge pressure, vibration, sound should be normal

3) Check the pump rolling a small amount of water leakage, leakage phenomenon of steam and smoke

4) Open the feed water pump export

5) Close the oxygen pump recirculation door

6) Comprehensive examination, put into standby pump interlock, according to the motor blast temperature, cooling water into the motor

2, water supply in addition to the normal operation of the oxygen pump maintenance

1, the current water supply oxygen pump 104 or less. 8 a, temperature rise
