Ensure top-notch reliability with the best drive for the job

Automated processes are standard follow within the meals business. Production efficiency just isn’t the one motivation, hygiene also performs a key position within the meals business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate how to design a drive to satisfy these requirements and incorporate both these targets.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to guarantee that the right drive is chosen to meet the excessive necessities for hygiene in the food industry, we often suggest our ADVANCED LINE air vane motors. All their exterior components are made from chrome steel and are impervious to normal cleaning brokers. The clean floor of these air motors is easy to scrub. The drives are so properly sealed with sturdy long-life radial shaft seals that no air can escape and equally no filth, water or other solutions can penetrate the motor. The motors are even proof against water penetration from generally used cleaning spray techniques. A moist surroundings is no concern for this motor. It may even be used underwater as within the case of many stirring functions. All our ADVANCED LINE stainless-steel motors are lubricated with food grade USDA-H1 grease and may be operated oil-free. A power reduction of approx. 10-20% based mostly on the technical information acknowledged within the product catalog should be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor must boast different options for such applications?
Answer: Yes. In many purposes, condensation can type in air provide lines. It is subsequently advisable that measures are taken to ensure that the motor just isn’t positioned on the lowest point in the system and that it can be flushed out with water. Many customers take precautionary measures, not only relating to the structure of the motor of their system, but additionally concerning the use of water separators or dryers in front of the drive. If all this isn’t potential, then we recommend a particular coating for those components throughout the motor’s inside that are produced from chrome steel. This is as a outcome of there is a restrict to the use of stainless-steel for heavy duty, high-speed inside parts. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you’ve any examples of the place your motors can be utilized in the food industry?
Answer: Stirring dough, transferring and cutting sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food trade purposes are infinite. I’ll describe a couple of applications in additional element, similar to the use of our ADVANCED LINE air motor in an agitator for the manufacturing of fruit juice. Our 300W air motor drives a propeller stirrer in a magnetic agitator at the velocity of seven-hundred rpm.
We even have the ideal drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy within the smallest of areas. The 900W high-torque motor with a nominal pace of 22 rpm overcomes a starting torque of 585 Nm and has a most diameter of sixty three mm.
Another application may be present in grinding mills and conveying systems for grain processing. In this case, the main target is on mud generation and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in potentially explosive environments. You will even find our motors used within the processing of meat, for instance in a semi-automatic meeting system for the manufacture of kebab skewers. In the skewer unit, two air motors are used to drive belts which pierce a wooden skewer by way of items of meat, onion and pepper. Pressure on the skewer is 38 kg and subsequently a high-power air motor with compact design is ideally suited to this application.
Question: What advantages does an air motor have over an electrical motor in such applications?
Answer: There are many arguments in favour of using an air motor: One of the main advantages is its high power density. Depending on the design, an air motor has solely a fifth of the mass of an electric motor, or a third of its size. This is particularly important when using a handheld device however in fact also for robotic systems the place the drive moves with the robot arm.
Heat also leaves the air motor chilly. In critical settings, compressed air is an unproblematic supply of power – it doesn’t compare to the hazards of electricity. The power output from the air motor over extensive torque ranges is almost constant. Air motors can due to this fact be optimally operated in a wide area of fluctuating masses. There is no downside with load being applied on the air motor till standstill, no damages are incurred. This means it’s less apt to stalling. After discount of the load, it’ll run once more instantly and any number of successive times. Air motor energy could be tailored simply by adjusting the operating stress. The velocity is lowered smoothly by throttling the air volume. Throttling supply air is really helpful when torque should also be significantly reduced. Exhaust air throttling ought to be chosen to reduce back pace without any serious affect on the torque.
Question: Air motors are often seen to be less environment friendly compared to electric motors. Can you comment on this statement?
Answer: Air motors and electrical motors can’t be in contrast on a one-to-one basis. The effectivity of a drive all the time is decided by the circumstances of the application. Let me use this example to elucidate: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is applied at lowered velocity over an extended time frame to safe the packaging tape. Electric motors can’t be loaded over a long period of time with out working the chance of overheating. Therefore, for this packaging machine, an electric motor would need to face up to excessive hundreds and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely totally different story with the air motor: Due to the beneficial torque characteristics of air motors, a lower-powered drive will suffice. You might choose an air motor with a nominal torque of 15 Nm and nominal velocity of 275 rpm. Since the working torque is beneath that of the nominal torque, the air motor runs near idle speed at 450 rpm under light load. The energy required for this air motor is due to this fact solely 430W. The energy stability of an air motor is seen in a very different mild when you suppose about that the air motor wanted for this packaging machine would only require a 3rd of the ability of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on decades of expertise in the field of air motors. เพรสเชอร์เกจลม have a broad range of excessive quality, globally in style industrial drive solutions. Are the ADVANCED LINE motors a special resolution for meals business applications?
Answer: It is true that our engineers have continued to optimise our air motors over the a long time and our standard program has been adjusted to satisfy the needs of our prospects. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our clients benefit from long-established reliable drive solutions for the meals industry and medical technology.
