Every industrial maintenance strategy must include regular motor maintenance. Unfortunately, even the most thorough maintenance routine cannot stop sporadic issues.

After all, for the cooling motors, manufacturers are increasingly using real-time monitoring tools and predictive maintenance models to help increase reliability. However, for many industrialists, this has yet to be a choice. There are still many ways to boost motor performance and dependability. 

In this blog, we will discuss different ways you can easily extend your motor life.

How to extend the life of cooling motors?

Most of these tips are already part of an excellent routine maintenance plan. However, increasing the frequency of your administration or performing spot-checks on vital motors can reduce the chances of full motor failure.

Proper lubrication. 

The effectiveness and dependability of a cooling motor are influenced mainly by lubrication. It's crucial to use the proper viscosity and type of lubricant. The two major drawbacks of an electric motor—heat and friction—are lessened through lubrication. To avoid impurities or excessive bearing wear, ensure the lubricant is clear of debris and that the correct lubrication levels are followed.

Routine cleaning.

Simple maintenance, like cleaning the motor, should be done regularly. Ensure all venting is unblocked, and keep the case clear of dust and debris. Avoid accumulating debris as often as you can. Additionally, be careful not to harm the casing or other essential components by cleaning the motor with anything other than approved materials and methods.

Proper cooling and voltage control.

Heat is an issue for continuous-running motors, even with good lubrication. Verify that there is sufficient cooling and that venting is possible. Additionally, use an oscilloscope to control voltage and ensure that the motor isn't receiving too much of it, which could make it malfunction and run hot.

Vibration tests and mounting checks.

Make sure the motor isn't vibrating excessively by using an ultrasonic monitor. Although some vibration is natural, excessive vibration can compromise load distribution and bearing alignment, which puts excessive wear on the motor. If a pulse occurs more frequently than is typical, ensure the motor mounts are tight and stable.

Practice proper storage and handling. 

It's essential to treat motors carefully when demounting them, whether for service or storage. Similarly, remember how they will be used when packing or storing motors. Degreasing, preparing for insulating resistance, and limiting condensation and moisture are all part of this. Even when the motor is not used, its long-term dependability should still be a key priority. 

Conclusion 

Cooling towers are used to cool and circulate water in settings such as oil refineries, petrochemicals, other chemical plants, thermal power stations, and HVAC systems. They release waste heat into the atmosphere by evaporating a water stream at a lower temperature.

The two types of industrial or HVAC cooling tower designs are closed-circuit and open cooling water systems. Although both kinds of towers have the same function, they approach water cooling differently.

In this article, we will discuss closed-circuit cooling towers and their importance.

What is a closed-circuit cooling tower?

A closed-circuit cooling tower involves no contact between the air and the cooled fluid. This type of tower features two distinct fluid circuits, the first of which is a bundle of tubes through which the hot water flows, and the second of which is a separate fluid circuit.

Although the chilled water never comes into contact with the air, the evaporative cooling provided by the air drawn through the cascading water is comparable to that of an open cooling tower. It needs much more energy to provide the same cooling as an open-circuit cooling tower.

Three reasons to choose closed-circuit cooling towers.

 No contamination of the primary circuit

For instance, most of the procedures used in manufacturing food require that the process fluid be kept free of contamination from the outside environment. Coils isolate process fluid from ambient air pulled in by the fans, keeping it clean anduntainted in a closed loop. Thus, closed-circuit cooling towers meet this necessity.

2. Reduction of freezing risk

Glycol can be added to process water to lower the fluid's freezing point because it constantly moves through heat exchange coils and never comes into contact with air. This can be a huge benefit, particularly in cold nations (such as those in Scandinavia, Russia, Canada, etc.) where temperatures routinely drop below zero.

3. A more straightforward system

A closed-circuit cooling tower is an alternative to a system made up of an open-circuit cooling tower and a heat exchanger. This has the following benefits:

A more straightforward plant design

Smaller environmental impact

Enhanced thermal effectiveness

Conclusion

This is all that you should know about closed circuit cooling towers.  Accordingly, you can now select the one you require.

While cooling towers are used for industrial purposes, they have been used for residential AC systems and multi-building manufacturing units. They help you maintain heat and temperature for your HVAC systems.

Based on the use cases, cooling tower sizes are different, as they vary depending on where you want to use them. That is why when installing a cooling tower, you must decide on the right size and consider quality material.  

When it comes to choosing the right size, certain factors need to be considered. Having the right-sized tower makes the system more efficient. On the other hand, if you don’t have a cooling tower of the right size, it may cause many issues in the future. 

Moreover, you can consider the below points to learn more about choosing the rightly sized cooling tower. 

Wet bulb temperature

WBT or wet bulb temperature is impacted by ambient air temperature and relative humidity. It measures the amount of water vapor the atmosphere holds. If you want to measure WBT, you will need a tool called a psychrometer. In order to use the tool, you have to place water on it, and after a while, you will know the temperature difference. 

Moreover, by knowing the correct WBT, you are able to assess the size of the tower you need for your commercial or residential facility.   

Approach 

When deciding on the cooling tower sizes, you will need to figure out the “approach” after knowing WBT. When you find it, you are required to see the difference between the WBT and cold water temperature. You will need to install large cooling towers if you receive a lower approach temperature. 

Many cooling tower manufacturers recommend that the approach should be between 5 and 10 degrees Fahrenheit for their cooling towers. 

Range of cooling 

It is one of the quickest processes to be done when it comes to cooling tower sizes. The range of cooling is nothing but the difference between the water temperature that exits machinery and the cold water temperature. 

Heat load 

Do you know what a heat load is? Well, you can use the range of cooling to find out the load of the tower. You can follow a particular formula to calculate the heat load. If you don’t know the formula, call a professional, as they will do the required things to determine the heat load. 

Other factors that impact cooling tower size   

After knowing all the above factors that help you decide the right cooling tower size, you may still be unable to do it. This is because other factors influence the result, including the chemical use of the tower.

Cooling Tower Systems

Cooling tower’s water pumps are made with several small parts that work together to make one working machine. Pumps for cooling towers are built to supply water to the tower's spray system. In this blog, we will discuss important components of cooling tower pumps. Read below to learn more.

Components of a cooling tower pump

The Pulley

The pulley on a water pump is specially designed to transfer the movement of the driving belt into the bearing spindle. In order to mediate the amount of torque that passes through, the pulley receives the engine's traction and serves as a medium between the two. 

It must be composed of sturdy materials because the drive belt exerts a lot of strain and force on it. Typically, steel, cast iron, or sheet metal is used to make the pulley. The goal is to create a sturdy, portable, and long-lasting pulley. 

Spindle bearing 

Following the pulley, this is one of the most crucial parts of the cooling tower  pump. It takes the rotating force coming from the pulley and transfers it to the impeller, which is the next part in line. 

The water pump's lifespan is solely a function of the bearing's design and construction. Metal balls make up the bearing, which turn and twist to perform its function.

Bearings come in two varieties: ball-ball and roller-ball. In comparison to the others, the roller ball design enables greater longevity and smoother operation. The majority of water pumps therefore feature a roller-ball design. 

Body

The cooling tower pump’s body is its fundamental component as it holds the liquid and serves it as the hub for all transfer operations. The other parts adhere to the body to form the water pump that is visible to the naked eye.

As a result, the water pump's body needs to be constructed from incredibly durable materials that can withstand the internal water pressure. Although some are constructed using cast iron, the majority of water pump bodies are made of lightweight aluminum. 

The body is attached to the pulley on one end and to the cooling system of the car on the other. 

Seal

Since the bearing is made of metal balls, the risk of corrosion is high. The component must therefore be shielded from any liquid exposure. The seal is installed to close the pump tightly and shield the bearing from any pollution. 

Any leak will prevent the water pump from producing enough pressure, which will cause it to malfunction. Therefore, the seal is crucial to maintaining the water pump's integrity.

Since the bearing is made of metal balls, the risk of corrosion is high. The component needs to be protected from any exposure to liquid. The seal is put in place to protect the bearing from any contamination and to shut the pump tight. 

If there is a leak, the water pump will not produce enough pressure and will fail. Hence, the seal plays an important role in keeping the water pump intact.

Impeller 

The impeller is a rotor that is used to increase the pressure and flow of liquid inside a water pump. In other words, the impeller is the engine that drives a water pump, and if it breaks, the whole thing can stop working.

So it turns while catching the liquid in its fins and enhancing its flow. The pulley and bearings produce the torque. The impeller's specs affect a water pump's effectiveness. 

Conclusion

A water pump performs an extremely vital function that ensures your industry works as smoothly as possible. The water pump is a vital part of every cooling system, providing a constant stream of coolant to the powertrain.
