Magnetic pumps are widely used in industries such as chemicals, pharmaceuticals, and environmental protection due to their unique design that effectively prevents medium leakage. However, there is a significant operational limitation with magnetic pumps—they cannot run dry. So, why is it that magnetic pumps can't operate without liquid? This article will provide a detailed explanation.

    Working Principle of Magnetic Pumps

    To understand why magnetic pumps cannot run dry, it's essential to grasp their working principle. Magnetic pumps transfer power through magnetic coupling. Typically, the driving end and the driven end of the pump are connected via a magnetic coupling, and the impeller inside the pump rotates under the influence of this magnetic force, thereby propelling the medium to flow.

    Unlike traditional mechanical seal pumps, magnetic pumps have a completely sealed pump chamber with no shaft seals, which eliminates the possibility of leakage. This seal-free design makes magnetic pumps particularly suitable for applications that require high levels of sealing, especially when handling toxic, flammable, or corrosive media.

    The Dangers of Running Dry

    When a magnetic pump operates in a dry condition, meaning the pump chamber is devoid of any liquid medium, the magnetic coupling and other components inside the pump continue to rotate at high speed. This can lead to several problems:

    1.Overheating:

    Under normal operation, the liquid medium inside the pump acts as a lubricant and coolant. Without liquid, friction between components generates a significant amount of heat. Since the pump is designed to be completely sealed, the heat cannot dissipate quickly, potentially damaging the magnetic coupling and other critical components due to the rapid increase in temperature.

    2.Damage to the Magnetic Coupling:

When running dry, the magnetic coupling may overheat, leading to demagnetization or damage, causing it to lose its ability to couple magnetically. This not only results in the loss of the pump's drive function but also can lead to overall pump failure, which can be costly to repair or replace.

    3.Wear and Tear on the Impeller and Bearings:

    In a dry-running state, there is no liquid medium to reduce friction, causing direct contact between the impeller and bearings, leading to significant wear and tear. This drastically shortens the pump's lifespan and can even result in sudden pump failure.

    How to Prevent Dry Running?

    To ensure the safe and efficient operation of a magnetic pump, it's crucial to avoid dry running. Here are some common preventive measures:

    1.Install a Liquid Level Detection Device:

    A liquid level detection device can be installed in the pump's inlet pipe or storage tank. If the liquid level is too low, the device automatically stops the pump to prevent dry running.

    2.Set Up Pump Protection Devices:

    By installing pump protection devices, such as temperature sensors or flow sensors, the pump can automatically shut down if the internal temperature becomes abnormal or if the flow is insufficient, thereby protecting the pump from damage.

    3.Regular Inspection and Maintenance:

    Regularly inspect the pump's operating conditions to ensure there is always sufficient medium inside the pump, and conduct timely maintenance to prevent dry running due to worn-out components.

    Conclusion

    The primary reason magnetic pumps cannot run dry is that they rely on the liquid medium for cooling and lubrication. Without the medium, the pump's components can quickly overheat and wear out, potentially causing severe damage to the pump. Therefore, understanding and implementing preventive measures to ensure that magnetic pumps operate under the right conditions is key to extending equipment lifespan and ensuring safe production.

PPS PET and PA parts nitrogen deburring machine

 

Cryogenic deflashing and deburring system is a process that employs cryogenic temperatures to remove flash on manufactured workpieces made of a wide range of plastics (and other materials) both thermoset and thermoplastic. Some examples of materials used include nylon, HD-PE, PPS, PET, polycarbonate, polypropylene, polyurethane, liquid crystal polymer, PA+GF, PC+GF, PEEK, and Acetal. Manufactured parts that have been successfully deburred include those made through injection molding, compression molding and extrusion molding.

 

 What is “Flash.”

“Flash” is a raised edge attached to the workpiece. It is an unwanted piece of material and requires removal. Many medical devices and other precision components are included in deflashing applications. Deburring accounts for a significant amount of the costs of manufacturing. The cryogenic deflashing process causes the flash or burr to become stiff or brittle and break away leaving a clean edge. There are three types of burrs that can be formed in manufacturing operations and can be classified by the physical manner of formation: Poisson burr, roll-over burr and Tear burr.

■Poisson Burr

A Poisson burr results from the tendency of a material to bulge at the side when compressed until permanent deformation of the plastic occurs.

■Roll-over Burr

A roll-over burr is a burr that is more of a chip that is bent rather that sheared. The resulting burr is usually comparatively larger. The process even removes recessed burrs in blind and through holes.

■Tear Burr

A Tear burr is the result of material tearing from a work piece rather than shearing from it.

In the cryogenic deflashing process, parts are loaded into a basket. A cryogem such as liquid nitrogen is used to cool the workpieces. After they are cooled they are tumbled with pellets- often a polycarbonate media ranging in size from 0.006 to 0.080 inches (0.15mm to 2.03 mm.) Sometimes cryogenic deflashing does not rely on a blasting action but rather on the tumbling of the parts to remove flash from the outer edges. The process can even remove recessed burrs in blind and through holes. The process does not affect the surface finish or the geometry of the part. Edges are maintained without rounding or removal of extra material and only the unwanted burrs are removed.

 

Cryogenic Deflashing Systems Advantages

Cryogenic deflashing equipements provides advantages over manual deflashing.

■The process maintains part integrity and critical tolerances. As it is a bath process the price per piece is far less as many more parts can be processed at the same time.

■Cryogenic deflashing is non-abrasive.

■As the process is computer controlled, the human operator variable is removed from the process.

■Mold life is extended by the cryogenic deflashing process. Instead of making a new mold a company may choose to deburr a manufactured part cryogenically and achieve the same product quality very much as they would with a new mold for a period of time until maintenance is performed.

Cryogenic Deflashing Works On Most Molded Parts

 

The computer-controlled process generates repeatable and reliable results. Many medical devices and other high value precision molded components are included in our vast array of successful deflashing applications. We have processed parts manufactured through injection molding, compression molding and extrusion molding.

Our cryogenic deflashing machine offers a fast and repeatable process to remove flash from plastic parts. Through freezing, tumbling and blasting polycarbonate media at your injection molded plastic parts, we are able to remove residual mold flash time and time again.

The Cryogenic Deflashing process was originally created to remove mold flash from rubber parts. We are able to deflash rubber parts that are injection molded, extrusion molded and compression molded. We have processed parts made of various durometers. We typically deflash rubber parts made of EPDM, neoprene, Viton, Buna-N, nitrile, natural gum, SBR, butyl, and other elastomers.

Our Cryogenic Deflashing machine is often used by molders who work with silicone rubber. Silicone rubber, by its nature, is very viscous causing it to flash during the molding process. The Pege’s Deflashing machine removes mold flash from silicone rubber parts. We deflash parts made of liquid silicone rubber and even special blends of silicone rubber that include conductive fillers such as silver, graphite, nickel.

Rather than invest in an expensive new or repaired mold tool, customers can elect to extend the functional life of their mold tool by adding the additional step of deflashing, to finish the part and remove any residual flash leftover after molding operations. It is economical to pay only a slight premium per part than to invest in a new molding tool that has a limited production life.

 

Cryogenic Deflashing is a fast and efficient process that provides complete removal of mold flash without affecting the surface finish. Therefore, it is a safe,clean and cost-effective alternative to traditional methods.

Parts are placed in a chamber, cooled, tumbled and impacted with plastic polycarbonate media. Mold flash is removed quickly and cleanly. No dust or residue remains after deflashing.

Cryogenic Deflashing is more cost-effective than labor-intensive hand deflashing by a significant margin. The cost to process parts can range from less than .01 cent to several dollars apiece. General rule of thumb: cost is between 10% and 20% of the value of the part, although each part must be considered on its individual
