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

Automated processes are commonplace practice in the meals trade. Production effectivity just isn’t the only motivation, hygiene also plays a key role in the meals industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate tips on how to design a drive to fulfill these necessities and incorporate each these goals.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to make certain that the best drive is chosen to fulfill the excessive necessities for hygiene within the food industry, we usually suggest our ADVANCED LINE air vane motors. All their exterior elements are created from stainless steel and are impervious to normal cleansing agents. The easy floor of these air motors is simple to scrub. The drives are so well sealed with sturdy long-life radial shaft seals that no air can escape and equally no dirt, water or other solutions can penetrate the motor. The motors are even proof against water penetration from generally used cleansing spray systems. A moist setting isn’t any concern for this motor. It can 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 can be operated oil-free. A energy discount of approx. 10-20% primarily based on the technical knowledge said within the product catalog must be taken into account 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 isn’t positioned on the lowest point within the system and that it might be flushed out with water. Many customers take precautionary measures, not solely regarding the format of the motor of their system, but in addition concerning using water separators or dryers in entrance of the drive. If all this isn’t potential, then we recommend a particular coating for those parts inside the motor’s interior that are created from stainless-steel. This is because there is a restrict to using chrome steel for heavy responsibility, high-speed inside components. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you might have any examples of where your motors can be utilized within the food industry?
Answer: Stirring dough, shifting and slicing sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals industry functions are endless. I’ll describe a few applications in additional element, such as the usage 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 pace of seven hundred rpm.
We also have the best 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 velocity of twenty-two rpm overcomes a beginning torque of 585 Nm and has a maximum diameter of 63 mm.
Another software may be found in grinding mills and conveying techniques for grain processing. In this case, the primary focus is on dust era and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in doubtlessly explosive environments. You will even find our motors used within the processing of meat, for instance in a semi-automatic assembly system for the manufacture of kebab skewers. In the skewer unit, two air motors are used to drive belts which pierce a wood skewer by way of items of meat, onion and pepper. Pressure on the skewer is 38 kg and due to this fact a high-power air motor with compact design is ideally suited to this software.
Question: What benefits 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 principle advantages is its high energy density. Depending on the design, an air motor has solely a fifth of the mass of an electrical motor, or a third of its size. This is especially vital when using a handheld gadget but of course additionally for robotic methods where the drive strikes with the robot arm.
Heat additionally leaves the air motor cold. In critical settings, compressed air is an unproblematic source of vitality – it doesn’t examine to the hazards of electrical energy. The power output from the air motor over wide torque ranges is sort of fixed. Air motors can therefore be optimally operated in a wide subject of fluctuating loads. There isn’t any drawback with load being utilized on the air motor until standstill, no damages are incurred. This means it is less apt to stalling. After reduction of the load, it’s going to run once more immediately and any variety of successive times. Air motor power could be adapted just by adjusting the operating strain. The velocity is lowered smoothly by throttling the air quantity. Throttling supply air is beneficial when torque must also be significantly reduced. Exhaust air throttling should be chosen to scale back velocity without any severe affect on the torque.
Question: Air motors are sometimes seen to be much less efficient compared to electrical motors. Can you touch upon this statement?
Answer: Air motors and electrical motors cannot be in contrast on a one-to-one basis. pressure gauge 2.5 นิ้ว of a drive at all times is dependent upon the conditions of the applying. Let me use this instance to elucidate: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is utilized at reduced speed over a long period of time to secure the packaging tape. Electric motors can’t be loaded over a protracted time frame without working the risk of overheating. Therefore, for this packaging machine, an electrical motor would need to face up to high masses and in consequence would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a very totally different story with the air motor: Due to the beneficial torque characteristics of air motors, a lower-powered drive will suffice. You could select an air motor with a nominal torque of 15 Nm and nominal speed of 275 rpm. Since the working torque is under that of the nominal torque, the air motor runs near idle pace at 450 rpm beneath gentle load. The energy required for this air motor is subsequently only 430W. The energy steadiness of an air motor is seen in a very completely different mild when you suppose about that the air motor needed for this packaging machine would only require a 3rd of the power of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on decades of experience in the subject of air motors. They have a variety of excessive quality, globally popular industrial drive options. Are the ADVANCED LINE motors a particular solution for meals industry applications?
Answer: It is true that our engineers have continued to optimise our air motors over the many years and our commonplace program has been adjusted to meet the needs of our clients. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our clients benefit from long-established dependable drive solutions for the food business and medical technology.
