Techniques and Equipment Used in Vertical Dynamic Balancing Machines for Pump Impellers

by vemcoblogs -
industrial water pump suppliers in Mumbai

Industrial water pumps play a significant role in various industrial applications, including large-scale manufacturing processes to water treatment plants. One of the most important factors to ensure pump performance and longevity is dynamic balancing. In this blog, we’ll explore the techniques and equipment used in vertical dynamic balancing machines for pump impellers, ensuring that industrial water pumps in Mumbai run smoothly and efficiently.

Importance of Dynamic Balancing: How Balancing Impacts Pump Performance and Longevity

Dynamic balancing is a crucial process that ensures pump impellers rotate smoothly without causing excessive vibrations. If pump impellers are imbalanced, it can lead to several issues, such as premature wear, excessive noise, and energy inefficiencies, all of which can drastically reduce the pump’s lifespan. Many of VEMC’s industrial water pump suppliers in Mumbai recommend that dynamic balancing is essential for high-performing and long-lasting pumps. Moreover, proper balancing minimises wear on the bearings and shaft, reducing maintenance costs and operational downtime.

Types of Balancing Machines: Overview of Vertical Dynamic Balancing Machines and Their Applications

Vertical dynamic balancing machines have a distinct geometric shape that’s designed specially to handle pump impellers. They allow the impellers to be mounted vertically, simulating their real-world operating conditions.

Two main types of vertical balancing machines are:

  • Single-Plane Balancing Machines

Single-plane balancing machines are designed for impellers that have relatively simple and symmetrical designs, where the imbalance tends to be located in a single plane (typically the centre). It is important to note that these machines are beneficial when the impeller’s thickness is small compared to its diameter, making it easier to address the imbalance in just one plane. Moreover, some of their distinct advantages include cost-effectiveness, and suitable for high-volume production where balancing needs are straightforward. They are also quicker in operation because they focus on a single plane of imbalance. For instance, small centrifugal pumps or fans use single-plane balancing machines.

  • Two-Plane Balancing Machines

Also known as dynamic balancing machines, they are useful for more complex impellers. They measure and correct imbalances in both the upper and lower planes, ensuring a more precise balance. These machines are typically used for larger, more sophisticated impellers, where imbalances can occur at different axial points. For example, impellers used in heavy-duty industrial water pumps in Mumbai require two-plane balancing to ensure stability and performance at high rotational speeds. Many of these machines have automated sensors to detect imbalances and calculate exact correction required using software.  

Measurement Techniques: Methods Used to Measure and Correct Imbalances in Pump Impellers

Vibration analysis is one such precision measurement technique which is deployed to accurately measure any imbalance in pump impellers. 

This technique uses sensors to measure the vibration levels of the rotating impeller, such as bearings, gears, shafts, and rotors to gauge insights into where imbalances occur. The sensors gather information on three key factors: frequency, amplitude, and phase. Frequency tells us how often the vibration happens, amplitude shows how strong the vibration is, and phase reveals the exact point where the vibration peaks. Vibration analysis uses smart algorithms to spot patterns in this data, helping to pinpoint issues before they turn into major problems. This early detection can prevent costly damage and keep equipment running smoothly.

Balancing Standards: Industry Standards and Guidelines for Achieving Precise Balance

Balancing standards for rotating machinery, including pump impellers, follow global guidelines such as the ISO 1940/1 standard, which sets tolerance levels for permissible unbalance. This standard is widely adopted by industries to ensure proper balancing, minimise wear and tear, and optimise machinery performance. 

In addition to this, IS/ISO 1940-1 (2003), IS 11723, and BS 6861 balancing standards are also used for field balancing of rotors in situ, specific industrial pump impellers, and for balancing quality and tolerances in specific types of rotating equipment.

For industrial water pump dealers in Mumbai, complying with these balancing standards is critical to ensuring pumps meet operational demands and builds trust with clients who expect reliable and efficient equipment.

Advanced Technologies: Use of Laser and Computer-Aided Systems for Enhanced Accuracy

Laser and computer-aided technologies have significantly improved the accuracy of dynamic balancing. 

  • Laser Alignment: Lasers are used to precisely measure the displacement and alignment of the impeller as it rotates. Since this is a non-contact method, it allows for extremely accurate measurements without physically touching the part.
  • Computer-Aided Balancing: Advanced software is used to simulate the balancing process and predict the necessary corrections. This speeds up the process and ensures that the balancing is done with higher precision and efficiency.

Best Practices and Advanced Techniques for Achieving Accurate Shaft Alignment in Pump Sets

by vemcoblogs -
industrial water pumps in Mumbai

Shaft alignment plays a crucial role in maintaining the efficiency and longevity of industrial water pumps. Misaligned shafts can cause increased vibration, premature wear, and energy loss, leading to costly repairs and downtime. For businesses especially those relying on industrial water pumps, achieving precise alignment is essential to optimise performance.

VEMC is one of the leading manufacturers of industrial water pumps in Mumbai. In this blog, we discuss the best practices and advanced techniques for achieving accurate shaft alignment in pump sets.

Understanding Alignment Principles

Shaft alignment is the process of adjusting the relative positions of two connected rotating components usually the pump and the motor so that their rotational axes are perfectly aligned. 

Accurate alignment is critical for:

  • Reducing wear on pump components like bearings and seals.
  • Minimising energy consumption by reducing friction.
  • Prolonging the lifespan of industrial water pumps and preventing breakdowns.

Tools and Equipment Required

To achieve accurate shaft alignment, specialised tools are required. Some of the most commonly used alignment tools include:

  • Laser Alignment Tools: Highly precise, these are the most reliable tools for ensuring accurate alignment.
  • Dial Indicators: A traditional yet effective method for checking alignment. They measure the difference in alignment between two shafts.
  • Straightedge and Feeler Gauge: Often used for rough alignment before more precise measurements are taken.

Using these tools ensures that businesses, especially industrial water pump suppliers, maintain high standards of efficiency and performance.

Thermal Growth and Soft Foot Correction

Thermal expansion and soft foot conditions are two critical factors to consider for long-term alignment accuracy.

  • Thermal Growth Considerations: Thermal expansion can cause significant misalignment as the parts can expand once the pump and motor heat up and cool down during operation. To account for this:
  • Take into consideration the difference in temperature between the cold and operating state.
  • Use advanced laser alignment systems that allow you to input thermal growth data, ensuring that the machine is aligned under both cold and hot conditions.
  • Soft Foot Correction: “Soft foot” occurs when one or more of the machine’s feet do not make full contact with the baseplate, causing distortion during operation. This can severely affect alignment accuracy. To correct soft foot:
  • Identify the issue by loosening and tightening bolts while monitoring movement.
  • Use shims to fill the gaps and ensure even contact across all feet.

Regular checks and adjustments for thermal growth and soft foot conditions are essential to maintaining long-term alignment accuracy.

Alignment Procedures

Here’s a step-by-step guide on how to perform accurate shaft alignment:

  • Initial Inspection: Check for visible signs of misalignment, such as excessive vibration or noise, and conduct a visual inspection of the pump and motor setup.
  • Rough Alignment: Before using precision tools, perform a rough alignment by adjusting the position of the pump and motor until their axes appear close to aligned.
  • Use Alignment Tools:
  • Attach a laser alignment tool or dial indicator to the shafts.
  • Take readings at multiple positions (e.g., 9 o’clock, 12 o’clock and 3 o’clock) to check the alignment.
  • Make adjustments based on the readings, shifting the pump or motor as needed.
  • Recheck Alignment: After adjustments, repeat the alignment measurements to ensure that the shafts are now aligned correctly.
  • Tighten Bolts: Once satisfied with the alignment, tighten the bolts and perform one final check to confirm no movement occurred during tightening.

Continuous Monitoring

Achieving alignment is not a one-time task. Regular monitoring is necessary to maintain accurate alignment over time. Continuous monitoring involves:

  • Regular inspections using laser alignment tools or dial indicators.
  • Recording alignment readings to spot gradual misalignment trends.
  • Prolonging the lifespan of industrial water pumps and preventing breakdowns.

The Takeaway

Accurate shaft alignment is essential for ensuring the efficiency and longevity of industrial water pumps. By continuously monitoring alignment, businesses can optimise their pump performance and reduce maintenance costs.

Preventive Strategies for Dewatering in Low-Lying Areas

by vemcoblogs -
industrial water pumps dealers in Mumbai

If you’re dewatering in low-lying areas, be prepared for some formidable challenges. Even a moderate amount of rainfall can cause significant water logging while stormy rains can inundate the areas completely and in a very short span of time. This calls for special preparedness. We at VEMC are one of the leading industrial water pumps dealers in Mumbai, and in this blog we talk about the preventive strategies you need for dewatering low-lying areas.

Difficulties of dewatering flood-prone areas

  • Dewatering flood prone areas requires you to be quick on your feet. This is because even a short amount of rainfall could quickly inundate the space giving you very little reaction time.
  • Due to high soil saturation, it can be quite difficult to drain away the water from the low-lying area.
  • Low-lying areas often have a high water table which can make it quite challenging to dewater it.
  • While dewatering the low-lying or flood prone area, there is a risk of continuous inflow of water from the nearby streams, lakes or rivers.
  • Dewatering a flood-prone or low-lying area can also have serious environmental concerns as it could lead to undesirable deposition of sediments in the nearby areas.
  • Finally, dewatering flood-prone areas is quite a costly affair as it requires the continuous engagement of men, material and equipment.

Proactive measures for dewatering

While the above difficulties may sound rather insurmountable, it is nonetheless possible to effectively dewater a flood-prone area. This is especially true if we follow a proactive strategies like French drains and sump pumps.

  • A French drain is made by using perforated pipe buried in a trench that is filled with gravel. It redirects water away from an area and prevents pooling in low-lying areas.
  • Sump pumps are effective in areas with a high water table. It is an equipment that helps remove water logged in a sump basin.

The right pumps to choose for dewatering

Dewatering a flood-prone area is quite challenging and hence your choice of pumps must be very careful. We at VEMC offer a wide range of dewatering pumps that can help you deal with the menace of inundation especially if you’re located in a low-lying area. Our Eterna CW/BW series for instance is a market leader thanks to its powerful performance, massive capacity and robust design. It offers a head of up to 70 meters and is specially suited for dewatering trenches, pits and foundations. It has especially found enormous use during the monsoon season, and has been a favourite of municipalities, builders and mall-owners.

However, in case flooding is frequent, it is best to go with permanent dewatering systems. These provide continuous drainage using systems like:

  1. Subsurface drainage systems
  2. Deep well dewatering systems
  3. Interceptor drains
  4. Tidal gates and flood barriers
  5. Stormwater management systems
  6. Retention and detention ponds

Pain points of traditional pump monitoring vs. the advantages of Kirlosmart

by vemcoblogs -

Monitoring pumps regularly and continuously is important. This is because any deviation in parameters can cause serious wastage of energy, wear and tear and drop in performance. Traditionally, pumps have been monitored by physically checking the parameters at the pump site and taking readings. However, with the advent of IoT, pump monitoring has been transformed like never before. VEMC is one of the top-notch industrial water pump suppliers in Mumbai, and in this blog we take you through the pain points of traditional pump monitoring and how Kirlosmart has  successfully overcome these.

Challenges of traditional pump monitoring methods

  1. Physical monitoring: Traditional methods require physical monitoring of pumps using equipment like flow meters. This meant the technician had to personally go to the site and take readings.
  2. Costly: Traditional monitoring techniques were costly as these involved visit by a trained technician or training of an in-house resource for monitoring pump performance.
  3. Passive: Traditional monitoring is non-continuous in nature, in the sense that it takes place far and in between during the pump’s working life. Otherwise, it is done when the pump exhibits unusual behaviour such as noise or too much vibration.

Kirlosmart: Next-gen monitoring

When it comes to monitoring pumps, Kirlosmart is the next-gen solution. It operates using the cutting edge IoT technology which keeps your pumps connected to your laptop or smartphone device through WiFi at all times.
