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

Automated processes are commonplace apply within the food industry. Production efficiency isn’t the one motivation, hygiene also performs a key function within the food 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 objectives.
Question: How are high requirements of hygiene met by DEPRAG?
Answer: In order to guarantee that the right drive is selected to meet the high requirements for hygiene within the meals industry, we normally advocate our ADVANCED LINE air vane motors. All their external components are produced from stainless-steel and are impervious to regular cleansing agents. The easy floor of these air motors is simple to clean. The drives are so nicely sealed with sturdy long-life radial shaft seals that no air can escape and equally no dirt, water or different options can penetrate the motor. The motors are even proof against water penetration from generally used cleansing spray systems. A moist setting is no concern for this motor. It can even be used underwater as in the case of many stirring functions. All our ADVANCED LINE stainless-steel motors are lubricated with meals grade USDA-H1 grease and could be operated oil-free. A power discount of approx. 10-20% based mostly on the technical data stated within the product catalog should be taken into account when designing drives for oil-free operation.
Question: Does an air motor need to boast different features for such applications?
Answer: Yes. In many purposes, condensation can kind in air provide lines. ชนิดของpressuregauge is therefore advisable that measures are taken to make certain that the motor isn’t located on the lowest point in the system and that it could be flushed out with water. Many customers take precautionary measures, not only referring to the structure of the motor in their system, but also regarding the usage of water separators or dryers in entrance of the drive. If all this isn’t potential, then we advocate a special coating for these parts inside the motor’s inside which are created from chrome steel. This is because there is a restrict to using chrome steel for heavy responsibility, high-speed inner elements. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you’ve any examples of where your motors can be utilized in the food industry?
Answer: Stirring dough, shifting and cutting sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals business purposes are endless. I’ll describe a few purposes in additional detail, similar to 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 on the speed of seven-hundred rpm.
We even have the best drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power within the smallest of areas. The 900W high-torque motor with a nominal speed of twenty-two rpm overcomes a beginning torque of 585 Nm and has a most diameter of sixty three mm.
Another application may be present in grinding mills and conveying techniques for grain processing. In this case, the major focus is on mud technology and explosion prevention. All our ADVANCED LINE motors are ATEX certified to be used in doubtlessly explosive environments. You will even discover our motors used in the processing of meat, for example 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 picket skewer via items of meat, onion and pepper. Pressure at 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 electric motor in such applications?
Answer: There are many arguments in favour of using an air motor: One of the principle advantages is its excessive power density. Depending on the design, an air motor has only a fifth of the mass of an electrical motor, or a third of its size. This is particularly significant when using a handheld gadget however after all also for robotic systems where the drive strikes with the robot arm.
Heat also leaves the air motor cold. In crucial settings, compressed air is an unproblematic source of vitality – it doesn’t examine to the hazards of electricity. The power output from the air motor over wide torque ranges is nearly fixed. Air motors can due to this fact be optimally operated in a large field of fluctuating masses. There isn’t any downside with load being applied on the air motor till standstill, no damages are incurred. This means it is much less apt to stalling. After reduction of the load, it’ll run once more immediately and any variety of successive occasions. Air motor power can be adapted simply by adjusting the working strain. The velocity is reduced smoothly by throttling the air volume. Throttling provide air is beneficial when torque must also be significantly decreased. Exhaust air throttling ought to be chosen to reduce back pace with none severe affect on the torque.
Question: Air motors are often seen to be much less environment friendly in comparison with electrical motors. Can you comment on this statement?
Answer: Air motors and electric motors can’t be compared on a one-to-one basis. The efficiency of a drive all the time is determined by the conditions of the application. Let me use this instance to clarify: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is applied at lowered speed over a long time period to safe the packaging tape. Electric motors can’t be loaded over a protracted period of time with out operating the danger of overheating. Therefore, for this packaging machine, an electric motor would wish to face up to excessive masses and as a result would need to be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely 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 speed of 275 rpm. Since the working torque is below that of the nominal torque, the air motor runs near idle speed at 450 rpm beneath mild load. The energy required for this air motor is due to this fact solely 430W. The vitality stability of an air motor is seen in a totally completely different gentle when you think about that the air motor needed for this packaging machine would only require a third of the facility of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on many years of expertise in the subject of air motors. They have a variety of high quality, globally in style industrial drive solutions. Are the ADVANCED LINE motors a particular resolution for food industry applications?
Answer: It is true that our engineers have continued to optimise our air motors over the decades and our commonplace program has been adjusted to satisfy the wants of our clients.
