Certain industries, such as the oil and gas industry, the chemical industry, the food and beverage industry, and the industry that treats wastewater, could not function as effectively without the use of progressive cavity pumps. Other industries, such as the food and beverage industry, also rely on these pumps. The foundation of the method is a concept referred to as rotary positive displacement, which is utilized in the process. Pumps of this type are sometimes referred to as multi-chamber pumps. In some communities, individuals may also refer to these as cushions. These pumps consist of a rotor, a stator, and cavities that are precisely measured and sized in between the two components. The dimensions of these cavities have already been decided upon.
These pumps are able to withstand high temperatures as well as rough conditions while they are being used because of their durable construction. There is a possibility that the performance of these pumps could be negatively impacted in the long run by a number of different factors. This could happen for a variety of reasons. Which of these considerations are going to be the focus of our conversation?
Failures of the Rotors and Stators of Progressive Cavity Pumps Can Often Be Traced Back to the Following Common Causes
The stator and the rotor are the names of two of the components that are necessary for the operation of the progressive cavity pump. The stator deteriorates over time as a result of the wear and tear that it experiences. The passage of time will bring about deterioration as a direct result of this, as expected. The frequency with which fluids that are abrasive and corrosive, materials that are composed of harsh chemicals, and materials that are semi-solid are transferred through the pump stator is another factor that determines whether or not a component needs to be replaced.
Rotor Defects Caused by Both Normal Use and Abuse in Addition to Everyday UseThe spindle-shaped rotor that is featured in this apparatus can be constructed out of a variety of different grades of stainless steel due to the wide availability of these materials. If, on the other hand, you work with liquids that have a consistency that is somewhere between liquid and solid, you need to replace the rotor and the stator at the same time in order to achieve the highest possible level of productivity. This is due to the fact that if the rotor wears out, it may cause some solid particles that were previously suspended in the fluid to leak out, which may then cause the stator to wear out even more rapidly.
Abrasion-related wear and tear:Abrasion happens when the plating on the rotor wears away, which has an effect on the connection that is made between the rotor and the stator as a result. This level of wear and tear can be traced back to abrasion as the contributing factor. When there is a buildup of acid on the surface of the rotor, this can take place.
Cyclic Stress: If the rotor is not installed in the correct manner during the process of installation, the outer part of the rotor may be subjected to an excessive amount of motion. This can cause cyclic stress. Because of this, there is the potential for cyclic stress to occur. As a consequence of this, the rotor is put through cyclic stress, which eventually leads to fatigue failure.
This can cause the elastomer to behave in a way that is known as hysteresis, which is a condition that can occur when an excessive amount of pressure is placed on an elastomer. Hysteresis is a condition that can occur when an elastomer is subjected to an excessive amount of pressure. This happens on its own as the pump ages over time; however, premature hysteresis can occur if the rotor is not inserted correctly or if the depth setting is not accurate. Both of these things can cause the pump to age prematurely.
If appropriate preventative and periodic maintenance is not performed, there is a possibility that the operation of the business, as well as its productivity, will suffer. This is the case regardless of the nature of the problem that has arisen.
Repairs and Preventative Maintenance of Equipment
It is necessary to perform maintenance on the pump either once a week or once a year, but the frequency of these tasks is determined by both the outward appearance of the pump and its overall functionality. Performing maintenance on the pump either once a week or once a year is necessary. It is strongly recommended that a check of thepump stator be carried out on a weekly basis in order to determine whether or not it is operating in the appropriate manner. During the course of this examination, one has the opportunity to carry out tests on a number of different physical parameters, such as the flow, pressure, noise, and temperature, among others. In relation to the process of performing routine inspections, the following are some useful pointers:
Make necessary alterations to the packaging, and at predetermined intervals, replace it entirely with a brand new one.
Verify that the shaft is in good condition before continuing.
No matter how thick or viscous the fluid is, each of these components of the progressive cavity pump works as a cohesive unit and contributes in their own special way to the process of moving the fluid through the pump. This is true regardless of the fluid's temperature or pressure. The rotors and stators of the pump can be thought of as its heart; in order to ensure that they continue to function properly, they require routine maintenance just like any other piece of machinery or equipment.
