The cooling fan with gridlock feedback technology refers to a technology used to prevent the fan motor from gridlock (that is, the motor shaft is stuck or unable to rotate) during operation. It monitors the speed and current of the motor in real time to determine whether there is a lock-up, and when it detects a lock-up, it feeds back to the control system to start the protection mechanism or take measures such as automatic stop, reverse or reduce the speed, etc. to avoid fan or motor damage. Locked-rotor feedback technology in high speed exhaust fan.

In the application of high speed exhaust fan, locked-rotor feedback technology is particularly important. High rpm exhaust fans are often required to provide strong airflow at high speeds, especially in electronic devices and industrial environments that require rapid heat dissipation.

The use of force sensors involves the following main steps:

1. Installation: When installing the force sensor, first check whether there are any scars on the surface of the product, whether the mounting bracket is firm and reliable, especially the cable and plug of the sensor, and avoid any external impact to prevent deformation. Avoid any external impact during installation, adjust the zero point to ensure the accuracy of the measured force value and the actual value. The force sensor should be kept away from heat and vibration sources, and installed in a constant temperature, humidity and dust-proof environment as much as possible. For small force sensors, install them on a stable, flat surface and make sure that the installation position can accurately reflect the actual force situation to avoid excessive force application and distortion.

2. Connect the circuit: Connect the transducer leads to a data acquisition system or signal conditioner. The transducer typically has four wires, two for power and two for signal output. Be sure the connections are made correctly to avoid signal loss or damage to the transducer.

3. Apply force: When applying force, be sure to apply the force in the direction of the sensor's measurement. The transducer's strain gages will deform slightly in response to the force, changing the resistance value. Small force sensors must be tested and calibrated at standard force levels to ensure accuracy and reliability of measurement results.

4. Acquisition of data: The resistance value of the load cell output is obtained through a data acquisition system or signal conditioner and converted into the corresponding force value. Typically, the change in resistance value is proportional to the magnitude of the force. For small force sensors, the calibration process includes placing the sensor under a standard force value for testing and recording the measurement results to determine whether the accuracy and stability of the sensor meets the requirements.

5. Analyze the data: According to the collected force data to analyze, you can get the size, direction and change trend of the force and other information, to provide a basis for subsequent control and decision-making. If the sensor output is found to be abnormal in use, it should be stopped immediately and reported to the relevant personnel for inspection and repair.

Maintenance and repair: the force sensor should be used according to the nameplate labeling temperature range, such as exceeding the difference should stop using. If the sensor output is found to be abnormal during use, it should be stopped immediately and inspected and repaired. 

In today's rapidly changing science and technology, force sensors as a modern industrial automation, intelligent key components, is with its unique charm to lead the new trend of future development.

Enterprises will customize the design according to customer needs and application scenarios to provide sensor products that are more in line with customer needs.

In the realm of force measurement, load cells and force sensors are indispensable tools for translating mechanical forces into quantifiable electrical signals.  However, achieving consistent and reliable measurements requires addressing several performance parameters, one of which is creep.  This phenomenon, though often subtle, can significantly impact the accuracy of force sensors over time.  In this blog, we’ll explore what creep is, why it occurs, and how it affects force measurement systems.

What is Creep? 

Creep refers to the gradual change in a force sensor’s output signal when a constant load is applied over an extended period.  Even if the applied force remains steady, the sensor’s reading may "drift" slightly over minutes or hours.  This drift is not caused by external factors like temperature fluctuations or vibrations but is inherent to the sensor’s material properties and design.

For example, if a 10 kN load is applied to a sensor, an ideal device would maintain a stable output (e.g., 10.00 mV) indefinitely.  In reality, creep might cause the output to drift to 10.05 mV after 30 minutes, even though the actual force hasn’t changed.

Why Does Creep Occur? 

Creep arises primarily from the viscoelastic behavior of materials used in force sensors.  Most load cells rely on strain gauges bonded to a metallic or composite structure (the "spring element").  When force is applied, the spring element deforms slightly, and the strain gauges measure this deformation.  However, no material is perfectly elastic—over time, internal stresses relax at a microscopic level, causing the material to deform further.  This slow deformation translates into a changing output signal.

Key factors influencing creep include:

1.  Material Selection: Metals like aluminum exhibit higher creep than stainless steel or alloy steels.  Polymers or composites may show even more pronounced effects.

2.  Load Magnitude: Higher loads amplify creep effects.

3.  Temperature: Elevated temperatures can accelerate creep due to increased molecular mobility.

4.  Sensor Design: A poorly optimized spring element geometry may concentrate stresses, worsening creep.

Impact on Measurement Accuracy

Creep is particularly problematic in applications requiring long-term static force monitoring, such as:

- Industrial weighing systems (e.g., silos, tank weighing).

- Structural health monitoring (e.g., bridges, buildings).

- Material testing machines (e.g., tensile/compression tests).

Even a small creep-induced drift can lead to cumulative errors in data logging or process control.  For instance, in a pharmaceutical production line, a drifting sensor might cause incorrect dosing over time, leading to product waste or regulatory non-compliance.

Quantifying and Compensating for Creep

Manufacturers characterize creep during sensor calibration.  A common test involves applying a rated load for 30 minutes and measuring the output deviation.  Creep is typically expressed as a percentage of the full-scale output (e.g., "±0.05% FS/30min").

To mitigate creep:

1.  Material Optimization: High-quality sensors use creep-resistant alloys (e.g., 17-4 PH stainless steel) and advanced composites.

2.  Design Improvements: Finite element analysis (FEA) helps optimize spring element geometry to distribute stresses evenly.

3.  Signal Conditioning: Modern amplifiers often include creep compensation algorithms.

4. Temperature Control: Active or passive thermal stabilization minimizes temperature-related drift.

Creep is a fundamental challenge in force sensor design, rooted in the physics of materials.  While it cannot be eliminated entirely, understanding its causes and mitigation strategies empowers engineers to select sensors with appropriate specifications for their applications.  When evaluating force sensors, always check the manufacturer’s creep rating and ensure it aligns with your measurement duration and precision requirements.  After all, in precision instrumentation, even the smallest drift matters!

By prioritizing creep-resistant technologies and smart compensation methods, modern force sensors continue to push the boundaries of accuracy and reliability in an ever-demanding industrial landscape.

When it comes to securing cargo during transportation, ensuring that loads are properly lashed down is crucial for both safety and regulatory compliance. Ratchet straps, with their efficient tightening mechanisms and reliable performance, are commonly used for this purpose. One key consideration when using ratchet straps is understanding their lashing capacity and how it impacts their safe usage.

The lashing capacity of a ratchet strap refers to the maximum load weight that the strap can safely secure in a particular application. This capacity is determined by various factors, including the material strength of the strap, the design of the ratchet mechanism, and the quality of the overall construction. It is essential to adhere to the specified lashing capacity to prevent overloading, which can lead to strap failure and pose serious safety risks.

Manufacturers typically provide the lashing capacity of ratchet straps in terms of both Working Load Limit (WLL) and Minimum Breaking Strength (MBS). The Working Load Limit indicates the maximum load that the strap can safely handle during normal use, while the Minimum Breaking Strength represents the point at which the strap will fail. It is important to note that the Working Load Limit is a fraction of the Minimum Breaking Strength, as a safety factor is built in to ensure reliable performance under varying conditions.

To determine the appropriate ratchet strap with the right lashing capacity for a specific application, it is essential to consider factors such as the weight and size of the load, the mode of transportation, and any regulatory requirements. Selecting a ratchet strap with a lashing capacity that exceeds the anticipated load weight helps to ensure a secure and safe transport operation.

In conclusion, understanding the lashing capacity of ratchet straps is critical for maintaining cargo security and transport safety. By adhering to the specified Working Load Limit and considering key factors in selecting the right strap for the job, operators can effectively secure their loads and mitigate the risks associated with improper strapping. Prioritizing safety and compliance through proper usage of ratchet straps contributes to efficient and successful cargo transportation.

When it comes to lifting and handling heavy loads, slings play a crucial role in ensuring safety and efficiency. There are various types of slings available, each designed for specific lifting applications. Understanding the different types of slings and their characteristics is essential for selecting the right equipment for the job. In this blog post, we will explore the three basic types of slings commonly used in lifting operations.

Wire rope slings are among the most durable and versatile lifting slings available. They are constructed from high-strength steel wire ropes that provide excellent tensile strength and resistance to abrasion. Wire rope slings are suitable for heavy-duty lifting tasks in rugged environments such as construction sites, shipyards, and industrial facilities. These slings come in various configurations, including single-leg, two-leg, three-leg, and four-leg designs, offering flexibility for different lifting applications.

Chain slings are another popular choice for heavy lifting operations. These slings are made up of alloy steel chain links that are incredibly strong and resistant to wear and tear. Chain slings are well-suited for applications where a high level of strength and durability is required, such as in steel mills, foundries, and machine shops. They are available in various configurations, including single-leg, double-leg, and multi-leg designs, offering different lifting capacities and configurations based on the load requirements.

Webbing slings, or synthetic slings, are made from woven synthetic materials such as polyester, nylon, or polypropylene. These slings are lightweight, flexible, and offer excellent load-bearing capacity while being gentle on the load surface. Webbing slings are commonly used in applications where non-metallic slings are preferred to avoid damage to delicate surfaces or where a lightweight lifting solution is needed. They are ideal for industries such as manufacturing, warehousing, and logistics, where lifting lighter loads and protecting the load surface are essential.

Each type of sling has its advantages and is suitable for specific lifting applications. Understanding the characteristics and capabilities of wire rope slings, chain slings, and webbing slings is crucial for ensuring safe and efficient lifting operations. By selecting the right type of sling based on the load requirements, environmental conditions, and safety considerations, operators can enhance workplace safety, protect the load being lifted, and improve overall lifting efficiency.

THJ Chemical Process Centrifugal Pump: Key Role in Evaporation Systems

I. Main Tasks of Pumps in Evaporation Systems

1. Material Transfer: The THJ centrifugal pump is crucial in evaporation and crystallization setups. It moves feedstock, intermediate products, condensate, and concentrated liquids between containers or pushes fluids through heaters and heat exchangers.

2. Circulation & Mixing: In some crystallization methods, the THJ pump keeps the solution circulating. This helps distribute heat evenly, stops hot spots, and ensures even crystal growth.

3. Flow & Pressure Control: By changing speed or valve settings, the THJ pump controls flow rates into evaporators and manages pressure in the system. This is key for consistent evaporation and crystallization.

4. Flow Rate & Head: It’s important to accurately figure out the flow and head needed for the system to avoid inefficient pump operation, which saves energy.

5. Corrosion Resistance & Materials: Since these pumps face acids, bases, and salts, they need to be made from tough materials like stainless steel, titanium, alloy steel, or have protective coatings.

6. Temperature & Pressure Tolerance: Pumps should handle high temperatures and pressures for reliable performance during intense crystallization.

7. Wear Resistance: With solid particles present, pumps need durable designs, like open impellers or special liners, to reduce wear.

8. Self-Priming & Cavitation Resistance: For jobs with frequent starts and stops or cavitation risks, pumps should be able to self-prime easily.

9. Sealing Systems: Double-face cartridge mechanical seals are best for handling abrasive materials while ensuring durability and staying eco-friendly.

10. Maintenance & Cleanability: Pumps that deal with crystallizing fluids should be easy to take apart for maintenance and cleaning.

11. Energy Efficiency: High-efficiency THJ pumps that meet industry standards can lower operating costs and fit well with eco-friendly practices.

II. Choosing Evaporation-Crystallization Pumps

THJ centrifugal pumps work differently from standard designs by using impeller thrust instead of just centrifugal force to move fluids:

1. Fluid Intake: The motor turns, creating a vacuum that pulls liquid into the pump.

2. Energy Transfer: Helical impeller blades create thrust, adding kinetic and pressure energy to the fluid.

3. Discharge: The fluid speeds up as it exits the pump, and the vacuum keeps the process going. This approach is great for high-flow, low-head tasks.

III. Industrial Uses  

THJ pumps are common in evaporation, crystallization, and chemical processes across various industries:

1. Phosphate Fertilizers: Used in phosphoric acid and ammonium phosphate production.  

2. Bayer Process Alumina: Circulates aluminum sodium solutions in evaporators.

3. Chlor-Alkali: Handles evaporation of caustic soda with salt.

4. Vacuum Salt Production: Circulates liquid in salt crystallizers.

5. Sodium Sulfate Plants: Manages Na₂SO₄ evaporation tasks.

6. Hydrometallurgy: Used in copper and nickel sulfate crystallization.

7. Alkali Refining: Works with NH₄Cl crystallizers.

8. Soda Ash: Recovers CaCl₂ in evaporators.

9. Pulp & Paper: Concentrates black liquor.

10. Power Plants: Involved in Flue Gas Desulfurization systems and ammonium sulfate crystallizers.

11. Light Industry: Used in alcohol, citric acid, and sugar evaporation.

NdFeB magnets are key products from Zoyn Magnetics, and they are some of the strongest permanent magnets out there, used in many industries. When we talk about NdFeB magnets, two types come up: bonded and sintered. Each has its own traits and uses, so knowing the differences can help you decide what's best for you.

One of the main differences lies in the manufacturing process. Strong sintered NdFeB magnets are made using a powder metallurgy process. The neodymium, iron and boron alloys are first ground into a fine powder. The powder is then pressed under high pressure in a mould to achieve the desired shape. Afterwards, the pressed powder is sintered at high temperatures to fuse the particles together to form a dense and strong magnet. In contrast, bonded NdFeB magnets are made by mixing neodymium powder with a bonding material, such as plastic or rubber. The mixture is then moulded or extruded into the desired shape, resulting in a more homogeneous structure of the magnet due to the even distribution of the binder.

These manufacturing differences can lead to variations in physical properties. Neodymium N52 disc magnet typically have higher magnetic strength. They have higher remanence (the magnetic flux density remaining after the magnetising field is removed) and coercivity (resistance to demagnetisation), making them ideal for applications that require a strong, stable magnetic field, such as electric motors and MRI machines. On the other hand, bonded neodymium magnets have lower magnetic properties. However, they excel in areas such as dimensional accuracy and complex shape forming. Complex shapes and thin-walled parts can be manufactured using bonded materials, which are difficult to achieve with sintered magnets.

Durability and corrosion resistance also differentiate these two types of magnets. Sintered neodymium magnets are susceptible to corrosion due to their porous structure, which is easily penetrated by moisture and other contaminants. As a result, they usually require additional surface treatments such as nickel-copper-nickel plating for protection. Bonded neodymium magnets typically have better inherent corrosion resistance due to the presence of a binder material. The binder encapsulates the neodymium particles, creating a natural environmental barrier that in many cases reduces the need for complex surface protection.

Cost is another important factor. Customized shaped Ndfeb magnets typically involve more complex manufacturing processes and often require additional post-treatment steps for surface preparation, which can drive up costs. Bonded neodymium magnets, which are simpler to manufacture and do not require extensive surface treatment, are often more cost-effective, especially in applications where magnetic strength is not a primary concern.

Both bonded and sintered NdFeB magnets from Zoyn Magnetics have their pros and cons. By understanding their differences, like how they're made, their physical properties, durability, and price, you can pick the right option for your needs, whether in electronics, automotive, or other fields.
