Boiler temperature reduction of feed water pump maintenance regularly

Boiler desuperheating water supply water pump maintenance is regularly in order to avoid the small defects become a big failure, small problems become big problems of the important measures, is to extend the service life of pump, improve equipment intact rate, create conditions to save energy. Regular service unit and local repair, overhaul and expansion of overhaul.

 

      1. Local repair

general arrangement in the running clearance or winter maintenance carried out in a planned way. Local repair projects mainly include: 1)

All adjustment boiler desuperheating water water pump regulator copper set with oil set check processing.

      2） Centrifugal pump inspection guide bearing. On the abrasion of rubber bearing, water leakage, journal wear, etc. To check, record and deal with. Oil guide bearing most of babbitt alloy steel bearings, soft, easy to wear and tear, such as sealing effect is bad, stop the oil basin, the water and sediment precipitation, runtime wear bearing, shaft neck. Especially for spraying or set package of stainless steel and carbon steel shaft neck, to understand its corrosion, wear, should be regularly check processing.

      3） The thermometer, meter, relay protection devices such as inspection, the inspection.

      4） The upper and lower guide bearing oil groove and turbine oil sampling test.

      5） Bearing clearance and tile surface inspection. According to the runtime of the thermometer temperature, purposeful check the bearing clearance and axial plane.

      6） Brake parts check processing.

      7） Unit parts fasteners, such as anchor bolt, shaft key, positioning pin is loose.

      8） Oil cooler appearance inspection and through the water test to see whether leakage phenomenon.

      9） Check the impeller, the vane and the impeller shell cavitation and abrasion of sediment, and its degree of measurement record.

      10） Measure the clearance between the impeller outer shell and blade.

      2. The outage

is a planned management, through the repair recovery technology situation of the unit. The unit of the damage is a damage, accident probability is small. Second, sexual damage, such as operation of the friction and wear, cavitation damage, silt wear and occurring probability is very small. 3 it is normal damage, such as various kinds of interference caused by vibration, the role of the ac stress and corrosion and electrical insulation aging, etc.

 

      3. Expand sex overhaul

when the water pump room due to foundation uneven settlement of unit axis offset, vertical concentricity change; Or parts serious wear and tear, damage, leading to a serious loss unit performance and technical and economic indexes and disintegration of the whole machine must be undertaken, repeat repair, replace, adjust and part of the reform.
