The seven skills of maintenance of sewage pump

the sewage pump has more and more get people's attention, from simply used to transport water to can transport all kinds of sewage and industrial waste water, construction drainage, liquid feed and so on. In use process, will inevitably encounter some problems. Effective maintenance can prevent many problems.
and sewage pump should be of personnel management and use, and regularly check the electric pump winding of the insulation resistance between the casing and is normal.
, especially for each use thicker than viscous medium, submersible electric pump should be run into clear water for a few minutes, to prevent the pump in the sediment, to ensure that the submersible sewage pump clean.
, diving sewage pump if long time need not when electric pump should be removed from the water, do not soak in water for a long time, to reduce the chance of motor stator winding be affected with damp be affected with damp, increase the service life of the electric pump, spray paint to paint falls off, so as to avoid rust.
, in the condition of conventional sewage pump per use - Hours after should include or replace oil in the oil chamber ( - Keep good lubrication oil, make the mechanical seal, improve the service life of mechanical seal.
, submersible non-clog sewage pump disassembly, repair, chassis components must be approved by. MPa air test examination, reliable sealing, to ensure that the motor testing pump should adopt the way of click, ensure that the product is normal before you start the motor.
and change the seal ring: in sewage medium after long-term use, clearance between the impeller and the sealing ring can increase, resulting in decreased water pump flow and efficiency, should turn off the switch, the pump lift, remove the bottom cover, remove the seal ring, according to the impeller seal rings with actual size, clearance is in commonly. Mm or so.
and small diving sewage pump can be used in a portable installations, caliber than mm coupling type submersible sewage pump recommended installation, maintenance and testing for later.
