High pressure balance serious corrosion resistant pump failure analysis

High-pressure self-balancing anti-corrosive pump serious fault points and the whole body failure and partial or individual serious failure two kinds. Overall serious fault occurs, the system stops running at the same time. While individual fault only partial or individual parts of damage or failure will not affect the normal work of the equipment, just stop part of the equipment, to start the standby equipment to continue running.

high pressure since the balance overall serious corrosion pump failure occurs:

head pressure levels below the maximum pressure of the pump ( The pump discharge line pressure) ; The import and export of pump pipe burst; Stop button not connected properly; Treatment method:

action downtime in the system, the order is: the output valve closed; Corrosion resistant pump motor power distribution cabinet tripping.

high self balancing individual serious corrosion resistant pump failure:

anti-corrosive pump motor fault; Lubricating oil pressure at 0. 1 mpa below; suction pressure is lower than the medium evaporation under 7 m; The water pump shell temperature greater than medium temperature above 35 ℃; bearing temperature above 70 ℃; Motor winding temperature over 120 ℃; Start the stagnation ( Corrosion resistant pump start-up instructions for 15 minutes, the output valve not open) Limited to linkage operation.

high-pressure self-balancing anti-corrosive pump failure:

light failures occur, mainly has the following kinds:

oil system oil pressure is lower than 0. 08 million mpa; Filter pressure difference is higher than 0. 06 million; output valve failure ( Overload, torque) ; The oil water pump motor fault;

action sequence: alarm light; Alarm is ringing, but corrosion resistant pump will not stop.
