More details please click high viscosity liquid pump.

What is viscosity?

The viscosity of a fluid can be regarded as a measure of how resistive the fluid is to flow, it is comparable to the friction of solid bodies and causes a retarding force. This retarding force transforms the kinetic energy of the fluid into thermal energy.

The ease with which a fluid pours is an indication of its viscosity. For example, cold oil has a high viscosity and pours very slowly, whereas water has a relatively low viscosity and pours quite readily. High viscosity fluids require greater shearing forces than low viscosity fluids at a given shear rate. It follows therefore that viscosity affects the magnitude of energy loss in a flowing fluid.

Below table is reference viscosity for normal liquids.

What liquid need a pump with heating jacket during transferring?

When transferring high viscosity liquids, such as resin, polyurethane, polymer, polyethylene, detergent, glue, sugar, chocolate and other liquids that are solidifying at room temperature. Liquid that flows easily by heating, and places that need to be insulated for outdoor installation in alpine regions.

What is the role of the heating jacket?

Most high viscosity liquids will decrease in viscosity with increasing temperature during heating, increased mobility for easy transfer. When the pump starts working in the cold region, or stop for some time, the first warm-up reduces the starting power of the pump and not damages the motor.

How does Bonve rotary lobe pump with heating jacket work?

Bonve rotary lobe pump heating jacket is built in pump chamber or pump cover. Heating medium keeps a circulation work in the jacket, and heat the transferred product. This way can make product flow more easily, so achieve efficient transfer. Heating mediums can be conduction oil, steam or hot water according to the site's conditions.

O-ring is essential in the assembly process of the pump. The O-rings material shall be different to adapt pumped liquid. Fluororubber and EPDM are typically to use. Why? The following are the characteristics of these two materials.

Characteristics of fluororubber

Good stability

Fluororubber has a high degree of chemical stability and is currently the best medium for all elastomers. Fluororubber resistant to petroleum base oil, diester oil, silicone ether oil, silicic acid oil, resistant to inorganic acid, resistant to most organic and inorganic solvents, pharmaceuticals, etc., only not resistant to low molecular weight ketones, ethers, Ester, amine, ammonia, hydrofluoric acid, chlorosulfonic acid, phosphoric acid hydraulic oil.

High temperature resistance

Fluororubber has the best high-temperature resistance in the current elastomer. Bonve Pump with FFKM material can be continuous working at 280℃.

Aging resistance

Fluororubber has excellent weathering resistance and ozone resistance. It has been reported that the VitonA developed by DuPont has been performing satisfactorily after 10 years of natural storage, and there is no significant cracking in the air having an ozone concentration of 0.01% for 45 days.

Excellent mechanical properties

Fluororubber has excellent physical and mechanical properties. Fluororubber 26 generally has a strength of between 10 and 20 MPa, an elongation at break of between 150 and 350%, and a tear strength of between 3 and 4 KN/m. Fluororubber 23 has a strength between 15.0 and 25 MPa, an elongation of 200% to 600%, and a tear strength of between 2 and 7 MPa.

Characteristics of EPDM rubber

Low density and high filling

The density of EPDM is a lower rubber with a density of 0.87. In addition, the oil can be filled in a large amount and the filler is added, thereby reducing the cost of the rubber product.

Strong anti-aging properties

EPDM has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil-filling properties and fluidity at room temperature. EPDM products can be used for a long time at 120℃, and can be used temporarily or intermittently at 150-200℃. Adding a suitable anti-aging agent can increase its use temperature. EPDM rubber can be cracked for more than 150h under the condition of ozone concentration of 50pphm and stretching of 30%.

Good corrosion resistance

Due to the lack of polarity and low unsaturation of EPDM, it has good resistance to various polar chemicals such as alcohols, acids, alkalis, oxidants, refrigerants, detergents, animal and vegetable oils, ketones and fats. However, it is less stable in aliphatic and aromatic solvents (such as gasoline, benzene, etc.) and mineral oil. Performance is also reduced under the long-term effect of concentrated acid.

The rotor pump is also called colloid pump, lobe pump or universal transfer pump, etc., and the rotor pump belongs to volumetric pump. For any mechanical equipment, whether the daily maintenance work has been done well? It is not only reflected in the normal production, but more importantly, it directly affects the service life of the mechanical equipment.

Rotor pump routine maintenance method.
1. Daily maintenance, whenever the machine does not work, according to the nature of the material to be transported, select the appropriate cleaning agent, the pump can be effectively cleaned, and finally have to be cleaned with water to ensure the pump is clean health.
2. Lubrication parts, the transmission gears, rolling bearings of the pump, must maintain good lubrication conditions, usually, always pay attention to the level of oil in the gear, give enough lubricant, and to ensure that the oil quality is pure, clean, regular.
3. Electrical system, around the electrical equipment, is not allowed to store equipment, substances or gases that destroy insulation. At the same time, it is necessary to keep the electrical equipment working in a dry environment. If it is difficult to avoid the need to add moisture-proof facilities.
4. The pump seal is divided into static seal and dynamic seal, the seal should pay attention to the surface without scratches or bumps. Otherwise, it will directly affect the sealing effect. For the dynamic seal, it will be affected by many factors such as the pressure and the corrosion of the transport medium, and the wear of the particles in the medium. If there is a slight carelessness, there is a possibility of leakage. Once the product leaks, it should be shut down and repaired in time, cleaned with a soft and clean cotton cloth, and coated with a layer of glycerin. After assembly, use the hand before you can start using it. If the repair is hopeless, replace the new one.

Bonve Rotor pumps are engineered to perfection with innovative design and stringent quality control to give you trouble free service. Welcome to contact us to learn more!

Not to do the product well, but to lower the price. This is normal in many industries. When our people get a little cheaper, they will be complacent. But actually, they lose more. The price is bad, the market is broken, and of course our people can return to the original level. However, the process of this repair will be lengthy and even cost the death of a batch. Sometimes, even a variety will disappear completely. The power of the new life is not from the moths who are not afraid of the deceased, but from the opponents who follow their own way and stick to their own quality positioning and price positioning.

Appropriate price is conducive to industrialization and scale, but the price is too low, and the industry is stifled without any means. This is the truth that has been proved by countless facts.
In the current market, if you go around, you will find that there is a serious surplus of similar products. The price is lower than that of a family. Which product makes money, and which product is sold by everyone, which style is sold well, everyone follows the style. The same variety, from 10 USD to 2 USD, there is no difference in packaging! Customers only look at the surface and feel that they are not too bad. In fact, in the invisible place, the gap is very big! But the customers don't know, they are staring at cheap buys, and slowly good things are starting to cut prices in order to survive! So, this is really an era of death!

Can you do it well if the price is overpriced? 80% has a poor prognosis. Just as the land is polluted, can you expect food to be free from pollution? This is also a daydream! The land is polluted, at least for a few years. Let the grass grow wild, purify all the pollutants, restore the original purity of the land, and then plant the crops. However, in the few years that this granule has not been harvested, many people are unable to keep going, either starving or migrating.

The truly respectable enterprise is not the fastest growing and expanding enterprise, nor the largest enterprise. It is a company that consistently creates business value and social value, and has its own bottom line. This is why Bonve has not been taking low prices for its pumps.

Basic Principle of Temperature Control in Liquid Nitrogen Blast Freezers

 

liquid nitrogen blast freezers utilize the heat absorption effect of liquid nitrogen evaporation to achieve cooling. The boiling point of liquid nitrogen at normal pressure is -196°C. During the evaporation process, it absorbs a large amount of heat, rapidly lowering the temperature inside the freezing chamber.

Temperature control in liquid nitrogen blast freezers can be achieved through the following methods:

 

• Built-in Temperature Control System

1. Temperature sensors continuously monitor the temperature inside the freezing chamber and send the data to the control system.
2. The liquid nitrogen spraying system adjusts the amount of liquid nitrogen sprayed according to the preset temperature requirements, ensuring precise cooling.
3. The automatic control system adjusts the spraying frequency and duration of liquid nitrogen based on the temperature sensor data, maintaining the internal temperature within the desired range.

• Adjustment of Liquid Nitrogen Supply

1. Valve Control:** By adjusting the valve opening on the liquid nitrogen supply pipe, the flow of liquid nitrogen can be controlled. A larger valve opening increases the liquid nitrogen supply, lowering the temperature, while a smaller valve opening reduces the supply, causing the temperature to rise.
2. Pressure Regulation:** Adjusting the pressure in the liquid nitrogen storage container changes the spray speed and flow of liquid nitrogen. Higher pressure results in a stronger spray, rapidly lowering the temperature, while lower pressure slows the liquid nitrogen supply, helping stabilize or increase the temperature.

 

Key Factors Affecting Temperature Control in Liquid Nitrogen Blast Freezers

 

In practical operation, the precision of temperature control may be influenced by various factors:

1. Initial Temperature of the Material

The temperature of the material before it enters the liquid nitrogen freezer directly affects the time and amount of liquid nitrogen needed to freeze it. The higher the initial temperature, the more liquid nitrogen is required to reach the target temperature.

 

2. Type and Density of the Material

Different materials have varying heat conduction properties. For example, foods with high moisture content (such as sea cucumbers or fruits) exchange heat faster during freezing, while denser materials take longer to reach the target temperature.

 

3. Sealing Performance of the Equipment

The sealing performance of the freezing chamber directly impacts temperature stability. Poor sealing can lead to cold air leakage, increasing liquid nitrogen consumption and causing temperature fluctuations.

 

4. Ambient Temperature

Fluctuations in the surrounding environment temperature can affect the stability of the temperature inside the freezing chamber. In high-temperature environments, the equipment needs to consume more liquid nitrogen to maintain low temperatures.

 

How to Precisely Control the Temperature in Liquid Nitrogen Blast Freezers?

 

1. Set a Reasonable Target Temperature

Set an appropriate target temperature based on the freezing requirements of different materials. For example, for deep-freezing premium ingredients like sea cucumbers, the target temperature can be set between -40°C and -60°C to ensure the material is fully frozen and retains its best quality.

 

2. Optimize the Liquid Nitrogen Spraying System

The spraying system is central to temperature control. By adjusting the spray volume and duration, the target temperature can be reached more efficiently. Additionally, choosing high-performance nozzles helps improve the even distribution of liquid nitrogen, enhancing freezing efficiency.

 

3. Regular Calibration of Temperature Sensors

Temperature sensors act as the "eyes" of the temperature control system. Regular calibration ensures the accuracy of the measurements, preventing temperature fluctuations caused by sensor errors.

 

4. Strengthen the Sealing Performance of the Equipment

Check the sealing strips, valves, and other sealing components to ensure that the cold environment inside the freezing chamber is not disturbed by leaks. Replace aging sealing materials when necessary.

 

5. Properly Manage Freezing Loads

During operation, the freezing load should be managed according to the equipment's rated capacity. Overloading can reduce freezing effectiveness, increase liquid nitrogen consumption, and cause wear on the equipment. For large quantities of items that need freezing, it is best to process them in batches to avoid overwhelming the system and causing temperature control issues.

The nitrogen gas discharged from a liquid nitrogen freezer must be properly managed to ensure both safety and environmental protection. While nitrogen itself is non-toxic, odorless, and chemically stable, its high concentration can reduce oxygen levels, posing a risk of oxygen deficiency. Therefore, multiple factors should be considered in its operation and management.

Below are the key steps and methods for handling nitrogen gas discharged from a liquid nitrogen freezer:

 

1. Ensure Proper Ventilation

• Install Ventilation Equipment: Ensure that the exhaust area is equipped with forced ventilation systems such as exhaust fans or air exchangers.
• Avoid Exhausting into Enclosed Spaces: Nitrogen should not be discharged directly into confined or poorly ventilated areas, such as basements or small rooms.
• Use Natural Ventilation and High-Level Exhaust: If forced ventilation is unavailable, exhaust outlets should be positioned at high levels to allow natural ventilation to dilute and disperse the nitrogen gas.
  
  

2. Install Nitrogen Monitoring Equipment

To detect nitrogen concentration in the exhaust area and prevent accidents, nitrogen monitoring devices should be installed:

• Oxygen Concentration Alarms: These alarms monitor oxygen levels in the exhaust area and trigger alerts when oxygen concentration falls below a safe threshold (typically 17%).

 

3. Select a Safe Exhaust Path

To ensure the rapid dilution and dispersion of nitrogen gas, a safe exhaust path should be chosen:

• Keep Away from Crowded Areas: Exhaust outlets should be located away from operators and public spaces to prevent nitrogen accumulation risks.
• Avoid Heat and Fire Sources: While nitrogen is non-flammable, high temperatures can affect the safety of surrounding equipment. Exhaust outlets should be positioned away from open flames or high-temperature machinery.
• Control Exhaust Direction: Use ducts or pipelines to guide the nitrogen gas outdoors or into a designated safe dilution area.

 

4. Dilution and Dispersion

Proactive dilution measures can help reduce nitrogen concentration and minimize potential hazards:

• Discharge into Open Spaces: Direct nitrogen gas into spacious, open areas to facilitate rapid dilution.
• Use Fans for Dilution: Install high-power fans at the exhaust outlet to promote nitrogen-air mixing and quickly lower its concentration.
• Leverage Natural Dilution: If fans are unavailable, ensure that the exhaust point is located in an area with good airflow, such as an outdoor high-altitude location.

5. Operator Safety Protection

Ensuring the safety of personnel during nitrogen exhaust operations is essential:

• Wear Appropriate Protective Equipment: If necessary, operators should use oxygen-supply devices or protective masks to prevent short-term exposure to low-oxygen environments.
• Set Up Safety Signs: Clearly marked warning signs such as “Low Oxygen Area” or “Nitrogen Exhaust” should be posted in the exhaust area to alert personnel.
• Conduct Regular Training: Operators should receive training on nitrogen’s physical properties, potential hazards, and emergency response measures.

 

6. Nitrogen Recovery and Reuse

SPEEDCRYO’s two-door and four-door liquid nitrogen freezers feature patented energy-saving pre-cooling technology (nitrogen gas recovery system). This system directs the waste nitrogen gas from one freezing chamber into an adjacent chamber, utilizing its residual cold energy to pre-cool the food. Pre-cooled food enters the liquid nitrogen freezer at a lower temperature, reducing freezing time and liquid nitrogen consumption.

 

Managing nitrogen gas discharged from a liquid nitrogen freezer is a process that requires careful attention to safety and environmental factors. Ensuring proper ventilation, selecting an appropriate exhaust path, and installing monitoring equipment are key steps. By properly managing nitrogen discharge, liquid nitrogen freezing operations can be carried out efficiently and safely. To meet the customized needs of different enterprises, SPEEDCRYO also offers free site planning and comprehensive cold chain solutions, ensuring optimal cold chain technology configurations at every stage.
