Experimental Study of Pump Pump Arrangement in Parallel to the Characteristics of a Centrifugal Pump Vibration One Level

Introduction

The reliability and efficiency of centrifugal pumps are crucial in various industrial applications, including water treatment, oil and gas production, and power generation. However, these pumps are often prone to vibration, temperature, and wear issues, which can lead to premature failure and costly downtime. This thesis presents an experimental study on the effect of load force on the behavior of a centrifugal pump one level operated in parallel. The main objective of this study is to analyze the large vibration that occurs in the centrifugal pump using the vibration stability limit method.

Background and Motivation

Centrifugal pumps are widely used in various industries due to their high efficiency and reliability. However, they are also prone to vibration, temperature, and wear issues, which can lead to premature failure and costly downtime. The symptoms of failure that often occur in the pump unit are allegedly caused by factors such as vibration, temperature, and wear. Therefore, it is essential to investigate the effect of load force on the behavior of a centrifugal pump one level operated in parallel.

Experimental Setup

The pump used in this study was a centrifugal pump with a maximum specifications of a 30 meter head, a maximum capacity of 5 liters per second, and 1850 watt power. The suction pipes were made of PVC with a diameter of 2 inches and a length of 0.86 meters, equipped with valves and manometers. The compressive pipe had a diameter of 3 inches with a length of 3.78 meters and was equipped with a valve, manometer, and flowmeter. The system static head was 0.77 meters, and the total head system reached 3.9 meters.

Vibration Behavior Testing

The vibration behavior testing began with the granting of force loads at a value of 2 kg, 2.2 kg, 2.4 kg, 2.6 kg, and 2.8 kg. The resulting vibrations were measured using the 908B Vibrometer Digital Hand Held Vibration meter. The measurement point was taken from eight locations, namely on the foundation P-01, P-02, P-03, P-04, P-05 pump, P-06, and Electromotor P-07, P-08. Measurements were made from axial, vertical, and horizontal direction.

Test Results

The test results showed that the lowest vibration occurred at the pump at point P-06 with a deviation value of 27.5 x 10^-6 m, while the highest vibration was found in electromotor at point P-07 with a deviation value of 170 x 10^-6 m. Based on ISO 10816-3 standards for vibration speed, axial averages were recorded at 2.64 m/s, vertical 0.795 m/s, and horizontal 1.39 m/s. These values ​​categorized vibrations in zone A (light green), which shows that the engine condition is good and can be operated without limits.

Analysis of Results

Analysis of the results showed that there is a close relationship between the pump head and the frequency of vibrations produced. The smaller the head, the greater the measured frequency value, while the greater capacity also produces a higher frequency. This indicates that the design and operation of the right centrifugal pump is very important to reduce the risk of failure due to vibration.

Conclusion

This study not only provides information about the characteristics of pump vibrations but also shows how operational factors can affect engine performance. This information is expected to be a reference for the development of more efficient machine maintenance and maintenance techniques, so as to extend the life of equipment and improve operational safety in the industry.

Recommendations

Based on the findings of this study, the following recommendations are made:

  • The design and operation of centrifugal pumps should be carefully considered to reduce the risk of failure due to vibration.
  • Regular maintenance and inspection of centrifugal pumps are essential to ensure their optimal performance and extend their lifespan.
  • The use of vibration monitoring equipment can help to detect potential problems early and prevent costly downtime.
  • Further research is needed to investigate the effect of other operational factors on the behavior of centrifugal pumps.

Limitations of the Study

This study has several limitations, including:

  • The study was conducted on a single centrifugal pump, and the results may not be generalizable to other pumps.
  • The study only investigated the effect of load force on the behavior of the centrifugal pump, and other operational factors were not considered.
  • The study did not investigate the effect of other parameters, such as temperature and wear, on the behavior of the centrifugal pump.

Future Research Directions

Future research should focus on investigating the effect of other operational factors on the behavior of centrifugal pumps, such as temperature and wear. Additionally, further research is needed to develop more efficient machine maintenance and maintenance techniques to extend the life of equipment and improve operational safety in the industry.
