What’s The Difference: Valves – Ball, Gate, And Globe Valve?

by vemcoblogs -

Some of the most important aspects of a fluid management system are controlling, regulating, and directing the fluid. This is made possible by devices known as valves. Both domestic and industrial valves are used to direct the flow, shut access, adjust pressure and prevent back-flow in the pipes. These are especially useful when a section of the piping is undergoing repair or maintenance. Each valve however is uniquely designed to meet specific plumbing needs. As dealers of some of the best industrial water pumps in Mumbai, let us explain the difference between a Ball, Gate, and Globe Valve.

Ball valve:

A ball valve has a hollow ball in the center through which the liquid passes. As long as the hollow ball is in line with the direction of flow of the liquid, it flows with ease. But as soon as the hollow is turned perpendicular to the direction of the flow, it completely stops. Even turning the ball using a long and easy-to-use handle above by 1/4 is enough to cut off the flow and immediately create a powerful watertight seal inside. These valves are easy to use, durable, reliable, and especially useful in times of emergency. But besides turning off the flow completely, a ball valve can also divert or alter the flow of the liquid through multiple ports.

Globe valve:

A globe valve is especially useful to modulate or throttle the flow of the liquid. Its spherical body has a stationary ring seat. On turning the knob, a disc-like device is released and raised upwards from the ring seat. The Z-shaped passage opened below allows the liquid to pass through the valve. You can turn the handle all the way up or only partially, depending on how much liquid you wish you let pass. They, therefore, function pretty much like kitchen faucets or hose bibs. Flow modulation and throttling is the biggest advantage of a globe valve as compared to all the others, which are mostly used to simply turn the flow on or off.

Gate valve:

Also known as a shut-off valve, a gate valve works by lowering a wedge-shaped metal gate to halt the flow. The gate is lowered or raised by twisting a wheel-shaped knob present on top of the valve. The greatest benefit of a gate valve is the gradual stoppage of flow rather than causing a sudden halt, also known as a “water hammer”. A water hammer causes the liquid to suddenly change direction or abruptly stop. These create pressure waves and loud banging noises inside the pipe. A gate valve is only useful to open or shut the flow of liquids rather than throttling the flow like a globe valve. A gate valve is best used in straight flow lines with minimal disruptions, restrictions, or diversions. You can actually get a physical demonstration of these valves from any dealer of industrial water pumps in Mumbai.

How to Calculate Total Dynamic Head for an Industrial Pump

by vemcoblogs -
TDH for an Industrial Pump

The total Dynamic Head in an industrial pump refers to the total pressure when water is flowing in a particular system. It has two parts: the vertical rise and friction loss. In this blog, we explain to you the complete calculation of the TDH. So let’s get started.

Broadly, the TDH of a pump can be calculated by following these steps:

  1. Calculate the value of the vertical rise 
  2. Find out the friction losses in the system as the water passes through the pipe and other components
  3. Add both these values to arrive at the TDH.
  • How to calculate the vertical rise:

As the name suggests, this parameter seeks to calculate the distance up to which the liquid has to rise from its starting point in the system below to the endpoint. If the liquid level at the bottom goes down, the vertical rise will naturally increase. Likewise, in case the level of liquid rises at the bottom, it has to rise over a shorter distance to reach the endpoint, and hence the vertical rise will decrease. With the increase of the value of vertical rise, the TDH also increases.

  • How to calculate friction loss:

To find out the friction loss, it is necessary to calculate the desired flow. The greater the flow going through your pipes more will be the loss due to friction. Friction loss also depends on the type of pipe in use, its vertical and horizontal length, and its schedule. You must also factor in the elbows, valves, connectors, or other components that come in contact with the liquid, and hence contribute to the friction loss. 

  • The result: Total Dynamic Head calculation:

As stated earlier, TDH is simply the summation of vertical rise and friction loss. To arrive at the TDH value, first ensure both are in the same units of length, say feet. For instance, if the vertical rise in the worst-case scenario is 25 feet, and the friction loss of the system is 6 feet, the TDH value would be 31 feet.

  • Alternative scenario:

Always considers the worst-case scenario in case of vertical rise to ensure you have sufficient amount of TDH. For instance, in the above case, if the water level never goes below 5 feet, the vertical rise will always be 20 feet and hence the TDH value will only be 26 feet.

Other Considerations When Calculating Total Dynamic Head

A few other factors also have an impact on the Total Dynamic Head. These include viscosity, specific gravity, and temperature. The specific gravity of a liquid can slightly alter the friction losses. Likewise, viscosity can significantly increase friction losses.

Success Story: The Installation of Vertical NK Pump sets at MCGM Mahim Pumping Station

by vemcoblogs -

This project was carried out at the sewage pumping station on Swami Vivekananda Road in Mahim, Mumbai. VEMC, a leading dealer of industrial water pumps in Mumbai, was proud to have bagged and worked on the project.

Pumping station | Egger Pumps

Nature of the Project

VEMC supplied vertical NK pump sets and valves to the MCGM Mahim Pumping Station. It also took over the successful supply, installation, testing, and commissioning of pump sets and associated valves.

Execution

The execution of this project happened in 4 stages:

  1. Procurement of material from KBL and Jyoti
  2. Pre-dispatch inspection of the motor in Gujarat, pumpset at KOV, and valves at Nashik in the presence of MCGM officials
  3. Dispatch of materials to the site
  4. Installation, testing, and commissioning of the installed system

Challenges Faced During the Project

The VEMC team faced quite a few roadblocks during the project:

  • The unloading phase was challenging. The unloading of material at the site was a bit difficult due to inadequate space for hydra. Moreover, the location was a high-traffic road and hence, a lot of intervention from the traffic police was required.
  • The installation location was 70 ft below the surface level. Hence, transporting the materials i.e., the pump and motors, to the location was not very easy.
  • Installation of valves in the existing pipelines because they were completely corroded.
  • Fabrication of duck foot bend from pump suction to the valve in CIDF.
  • During the delivery stage, dismantling the joint connections seemed a bit difficult due to space constraint and fitting issues.

How VEMC Overcame the Roadblocks

VEMC took proactive steps to ensure that the execution went smoothly. Here are the ways in which we overcame the challenges:

  • Completed the unloading work at night to avoid traffic issues
  • Closed penstock gates every night during the installation of suction valves. This was carried out efficiently even though it was difficult since sewage water was blocking the valve path.

Safety Measures Taken During the Project

VEMC ensured that the entire execution happened in adherence to all safety measures. To this end, all team members were provided with safety hand gloves and shoes.

Takeaways

Some major takeaways from the project were:

  • Execution planning and how to align the execution with the bar chart/methodology
  • Time management to ensure the project was closed within the stipulated time

Outcome of the Project

With VEMC’s successful installation, the client experienced smoother operations as well as reduced maintenance needs and costs.

Methods, Tips & Precautions for Construction Dewatering

by vemcoblogs -

Dewatering is the removal of water, where it is drained out by pumping from a particular location. Basically, dewatering provides a dry foundation to work on by reducing the ground water table of the site. Whether you are constructing, running sand, or repairing sewers, dams, buildings, tunnels, or a basement, dewatering can prove very useful.

Choosing the right method for your project is very important. There are four main methods of dewatering — the well point method, eductor wells, open slump pumping, and deep well point method. Let’s take a look at them.

Well Point Method

In the well point method, the groundwater is channelled by the pump through the header pipe before getting discharged. This is a fairly, flexible and cost effective method under a wide variety of soil conditions.

Educator Well

This dewatering method is a lot like the well point system, but instead of a vacuum, high-pressure water is used to draw water into the well points. This method can be an effective in soils that are less permeable.

Open Slump Pumping

In the open slump pumping method, slumps and drains are constructed at one or more points of the excavated pit. These then collect the groundwater. This is one of the most convenient and cost-efficient methods.

Deep Well Point Method

The deep well point method is appropriate for a deep excavation when a large amount of groundwater needs to be removed.

Precautions to Take in Dewatering

  • Make sure to conduct the process under special supervision and look out for any signs of instability or soil erosion.
  • Do not pump the water directly into slopes.
  • Used a wooded buffer if you can.
  • Choose an appropriate area to discharge the water, ideally a forest buffer zone.
  • Ensure that the channels used for dewatering are stable and covered by vegetation or grass if possible.
  • Avoid dewatering during heavy rains.
  • When removing water that is contaminated with chemicals, grease or oil, do not discharge it directly. Use an oil-water separator before disposal.
  • Make sure you have all the relevant permits and licenses for dewatering before discharging water.
  • Check and verify the state of the water table at the location of dewatering. If it is too close to the surface, the plan may not work.

How Can You Mitigate a Mechanical Shaft Seal Leakage?

by vemcoblogs -
  • How Can You Mitigate a Mechanical Shaft Seal Leakage?

Why does leakage occur in a centrifugal pump? To understand this, we must first understand how a centrifugal pump basically works. As fluid goes through its impeller eye and up the impeller vanes, it starts with low pressure and velocity. As it flows into the volute and gets ready to exit, both the pressure and velocity increase. As the fluid flows out through the discharge, the pressure is high but the velocity gets reduced. The flow then goes out of the pump, which makes the pump exert pressure and raise the energy of the fluid.

When a component of the pump such as static joints and hydraulic malfunction, the whole system might break down. However, a majority of pump failures happen due to the mechanical seal of the pump malfunctioning.

A mechanical seal controls the leakage between a liquid and a rotating shaft. To do this, essentially all seals have to leak in order to maintain a film of fluid over the whole face of the mechanical seal. The leakage from the atmospheric side is quite less. But the leakage between the mechanical seal shafts and sleeves can cause significant issues. Often, the reason these happen is because of the fretting of the O-ring seal on the shaft. You will notice substances dripping from behind the seal close to the drive collar. Polishing the fretted part can provide a temporary fix, but it will not give you a solution. Here are some options you can choose in the short and long term:

Short term solutions

Replacing the shaft could be a practical option given that the maintenance cost is low and you would not have to overhaul the entire pump system.

When repairing or replacing the shaft is proving to be difficult, you can opt for a modified seal but you may have to plan in advance.

You can try relocating the O-ring of the seal sleeve with the help of a local technician. When you get to the bottom of the issue, you can check where the damage on the shaft is and shift the O-ring accordingly. If you still require a new sleeve, the cost will be only a little bit higher.

Long-term solutions

Upgrade the shaft to a higher quality material.

Consult a pump technician and coat the shaft below the seal sleeve with a substance like tungsten carbide. How much of the shaft you may need to coat will depend on the damage. Avoid the area around the drive collar set screws. Make sure to enlist professional support for this.
