Resistance to high temperature desulfurization denitration circulating pump key how to operate? Pay attention to?

high temperature desulfurization denitration circulating pump operation:

check before starting the:

check desulfurization denitration circulating pump bolts are tight, there should be used in the dynamic coupling plate or shaft before commissioning, check whether to correct, operation is flexible, such as plate fixed or have abnormal sound, should be timely check, check the first from the outside by hand to check whether the coupling level, from the mirror of oil in the bearing hole to see if the location of the lubricating oil in the oil mirror (near the center line of Too much should be put off some, too little should add some) 。 Check and plate movement, if the problem still exists, be about to dismantle the pump ( Based on the structure figure according to specifications and disassembling procedures) Check, clean house. And make record.

high temperature desulfurization denitration circulation water pump start up operations:

1, will be filled with liquid pump.

2, open the inlet valve in time, Such as inlet valve for one-way check valves do not need artificial operations) 。 Pay attention to the position of the inlet valve opening to maximum.

3, connected power supply.

4, open the outlet valve.

high temperature desulfurization denitration circulating pump operation notice:

1, run if any abnormal sound, or the abnormal cases such as heating, motor should stop machine inspection, inspection method and operation before checking method.

2, there is no water, should be kept in the operation of the motor to prevent motor be affected with damp be affected with damp.

3, regularly check whether the lubrication oil in the bearing need to be replaced.

4, the joint of water pump and pipeline should keep good air tightness, especially feed line must not leak by.

5, should grasp the running situation, timely check current, voltage change, as well as the bearing temperature rise is not higher than 75 degrees, the prevention of accidents.

6, such as found in the process of abnormal voice immediately stop operation, check the reason.

high temperature desulfurization denitration circulating pump stop:

turn off export valves, cut off the power and stop the shaft seal water. Desulphurization pump

high temperature desulfurization denitration circulating pump use note:

1, must meet the conditions, the flow and head should performance of advanced and reasonable structure, stable operation;

2, sealing components is tight and reliable performance, long service life.

3, pump under the condition of corrosion and heat-resistant, install and disassemble because it is easy to maintain.

4, light structure, cost cheap, energy conservation and economy.
