Titanium alloy centrifugal pump defects and treatment methods

titanium alloy centrifugal pump magnetic pump and common faults and processing methods summary

titanium alloy centrifugal pump magnetic pump and has strong corrosion resistance, resistance to acid and alkali is suitable for conveying any concentration of corrosive medium, anti-corrosion pump can be divided into, fluorine plastic centrifugal pump, fluorine plastic magnetic pump, stainless steel centrifugal pump, stainless steel magnetic pump, anti-corrosion wear-resistant pumps, users in the use of titanium alloy centrifugal pump, magnetic pump often appear what problem, need how to deal with?

1, the pump is not drainage

defect analysis: titanium alloy centrifugal pump pump priming lack; to wrong, Mesh, suction tube obstruction; Suction height is too high, or import liquid supply the lack of absorption, the suction vacuum.

processing methods: water pump priming from scratch; Again to determine the titanium alloy centrifugal pump rotation direction; Clean strainer, dredge the suction pipe; Adjust import pipeline, absorption is higher than the pump imports, adjusting the upper part of the pump for the hydraulic system, to ensure that the medium supply abundant.

2, run overload

defect analysis: poor quality of titanium alloy centrifugal pump motive, stator conflict; Liquid density increase; Packing gland too tight or dry conflict; Bearing damage; High speed; shaft winding; The axial force balance equipment failure; Coupling on the bad or the axial gap is too small.

processing method: check the replacement motor; Loosen packing, check the water pipe; Check and replace the bearing; Check the engine speed and power; Check the pump shaft; Check whether the balance is empty, return pipe is blocked.

3, pump suction

defect analysis: titanium alloy centrifugal pump suction valve have sundry or did not open, or suction tube obstruction; priming system faults

processing method: open the suction valve, eliminate clutter, dredge the suction pipe. Check the titanium alloy centrifugal pump pipe road, especially section pressure test connection flange, plugging. Replace the shaft seal, compression packing seal.

4, shaft seal overheating

defect analysis: too tightly on the packing; Mechanical seal has faults.

processing methods: adjust the sealing pressure; Inspection, repair or replace the mechanical seal.

5, pump drainage after interruption

defect analysis: inhalation of titanium alloy centrifugal pump pipe road leak; Suction side by foreign bodies blocked suddenly, or import filter blocking absorption; Suction pipe dehydration, a lot of gas suction

processing method: check connection place suction side and the gland seals; Stop pump, cleaning filter, channel inlet line; Check whether the suction line is break, parallel import pipeline valve is opened.

6, bearing overheating

defect analysis: titanium alloy centrifugal pump lack of lubricating oil, oily or aging; Cooling water lack or open circuit.

processing method: add sufficient oil or oil change; After checking add to the amount of water.
