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

Automated processes are normal practice within the meals trade. Production effectivity just isn’t the one motivation, hygiene additionally performs a key position in the food industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate the way to design a drive to satisfy these requirements and incorporate each these targets.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to make certain that the proper drive is selected to fulfill the high necessities for hygiene in the meals trade, we often recommend our ADVANCED LINE air vane motors. All their exterior elements are produced from chrome steel and are impervious to regular cleansing agents. The smooth floor of those air motors is straightforward to wash. The drives are so well sealed with durable 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 resistant to water penetration from commonly used cleaning spray systems. A wet environment is no concern for this motor. It can even be used underwater as within the case of many stirring applications. All our ADVANCED LINE stainless-steel motors are lubricated with food grade USDA-H1 grease and may be operated oil-free. A power discount of approx. 10-20% based on the technical knowledge said within the product catalog ought to be taken into account when designing drives for oil-free operation.
Question: Does an air motor need to boast other features for such applications?
Answer: Yes. In many functions, condensation can type in air provide lines. It is due to this fact advisable that measures are taken to ensure that the motor just isn’t situated on the lowest point in the system and that it can be flushed out with water. Many customers take precautionary measures, not only referring to the layout of the motor of their system, but in addition regarding using water separators or dryers in front of the drive. If all this isn’t potential, then we advocate a particular coating for these parts throughout the motor’s inside that are made from chrome steel. This is as a outcome of there’s a limit to using stainless steel for heavy responsibility, high-speed internal components. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you may have any examples of where your motors can be used in the food industry?
Answer: Stirring dough, moving and slicing sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the food industry applications are infinite. I’ll describe a number of functions in more element, such as using 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 on the pace of seven hundred rpm.
We also have the perfect drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy within the smallest of spaces. The 900W high-torque motor with a nominal speed of 22 rpm overcomes a starting torque of 585 Nm and has a most diameter of sixty three mm.
Another utility could be found in grinding mills and conveying techniques for grain processing. In this case, the main 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 discover our motors used within the processing of meat, for example 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 picket skewer by way of pieces of meat, onion and pepper. Pressure on the skewer is 38 kg and therefore a high-power air motor with compact design is ideally suited to this software.
Question: What benefits does an air motor have over an electric motor in such applications?
Answer: There are many arguments in favour of using an air motor: One of the principle benefits is its high energy density. Depending on the design, an air motor has only a fifth of the mass of an electrical motor, or a 3rd of its dimension. This is particularly important when using a handheld gadget however in fact 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 dangers of electrical energy. เกจ์วัดแรงดันน้ำ from the air motor over extensive torque ranges is almost fixed. Air motors can subsequently be optimally operated in a large subject of fluctuating loads. There is not any drawback with load being utilized on the air motor till standstill, no damages are incurred. This means it is less apt to stalling. After discount of the load, it will run once more instantly and any number of successive occasions. Air motor energy can be adapted just by adjusting the working pressure. The speed is lowered smoothly by throttling the air volume. Throttling supply air is beneficial when torque should also be considerably decreased. Exhaust air throttling should be chosen to reduce pace with none critical affect on the torque.
Question: Air motors are sometimes seen to be much less environment friendly compared to electric motors. Can you touch upon this statement?
Answer: Air motors and electric motors can’t be compared on a one-to-one basis. The effectivity of a drive all the time is determined by the conditions of the appliance. Let me use this example to explain: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is utilized at lowered pace over a long period of time to safe the packaging tape. Electric motors can’t be loaded over a protracted time period with out working the risk of overheating. Therefore, for this packaging machine, an electrical motor would want to withstand high loads and consequently would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a very different story with the air motor: Due to the favourable torque traits of air motors, a lower-powered drive will suffice. You could choose an air motor with a nominal torque of 15 Nm and nominal velocity of 275 rpm. Since the working torque is under that of the nominal torque, the air motor runs near idle pace at 450 rpm under mild load. The power required for this air motor is subsequently solely 430W. The vitality balance of an air motor is seen in a completely completely different gentle when you assume about that the air motor wanted for this packaging machine would solely require a 3rd of the facility of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on many years of expertise within the field of air motors. They have a variety of excessive quality, globally well-liked industrial drive solutions. Are the ADVANCED LINE motors a special resolution for food trade applications?
Answer: It is true that our engineers have continued to optimise our air motors over the a long time and our normal program has been adjusted to satisfy the needs of our prospects.
