Progressive cavity pumps are critical for oil and gas, pulp and paper, chemical, food and beverages, and wastewater treatment businesses. They work on the principle of rotary positive displacement. Progressive Cavity Pumps are intended to deal with viscous liquids and slurries with solids and particulate matter at a consistent flow. These pumps contain a rotor and a stator with a fixed size in the middle between them. The performance of a progressive cavity pump entirely relies upon these basic parts.
These pumps are intended to oppose high temperatures and
unforgiving working circumstances. Be that as it may, considering the sort of
strain these pumps bear and the general wear they go through, they require
occasional support, and fix, and may likewise require new parts. Many elements
might influence the presentation of these pumps over the long run. What are
those factors that pump manufacturers should keep in mind?
Common Reasons
for Failures of Rotors and Stators in Progressive Cavity Pumps
Of all the ever-evolving progressive cavity pump spare
parts, the stator and rotor might be supplanted more frequently than the
others. Here is a portion of the normal reasons for disappointment in rotors
and stators:
Wear and Tear of the Stator: The stator's consistent
turning activity makes grating to some degree. This prompts mileage throughout
the time. The recurrence at which destructive and rough liquids, cruel synthetics,
and semi-strong materials are moved through the pump additionally chooses the
requirement for substitution of the part.
Mileage of the Rotor: The shaft-formed rotor can be
produced using different grades of hardened steel. While it very well might be
prudent to supplant the rotor and the stator simultaneously, the rotor doesn't
wear out as quickly as the stator. Notwithstanding, if you manage semi-strong
liquids, it is prescribed to change both the rotor and stator in one go.
Wear Because of Abrasion: While the plating on the
rotor becomes broken down, it causes scraped area, which influences the
association between the rotor and the stator.
Corrosive Assault: The rotor might experience a
corrosive assault if the pH of the liquid falls under 6. This strips off the
plating bringing about a harsh surface.
Cyclic Stress: If the rotor isn't embedded as
expected during establishment, the external piece of the rotor can encounter
unnecessary movement. This outcome in cyclic pressure and resulting exhaustion
disappointment of the rotor.
Run Dry: if there should be an occurrence of a
stator, its elastomer can foster breaks on the off chance that a pump dries up,
with next to no liquid.
Hysteresis: in the event of an overabundance of
tension on the elastomer, a condition called hysteresis can happen. This
happens because of the maturing of the pump; notwithstanding, untimely
hysteresis might happen because of inappropriate rotor inclusion or erroneous
profundity setting.
Locked Induction Motor: Because of a secured
enlistment engine, the three-stage windings of a stator might be harmed.
All these
progressive cavity pump parts together function as cohesive units and
contribute in their own way to getting the fluid through, no matter how vicious
it is. The rotors and stators are almost like the heart of the pump and like
any other machine or equipment, they need to be maintained well. If you
discover any changes in the operations of your pumps, find out if they need to
be replaced or repaired. Risansi Industries Ltd. is a trusted supplier and industrial
