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

Automated processes are commonplace practice in the food business. Production effectivity is not the one motivation, hygiene additionally performs a key role within the meals trade. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss tips on how to design a drive to satisfy these necessities and incorporate each these targets.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to ensure that the right drive is chosen to fulfill the high requirements for hygiene in the meals trade, we usually advocate our ADVANCED LINE air vane motors. All their exterior parts are created from stainless steel and are impervious to normal cleaning brokers. pressure gauge วัด แรง ดัน of those air motors is simple 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 options can penetrate the motor. The motors are even resistant to water penetration from commonly used cleaning spray techniques. A moist environment isn’t any concern for this motor. It may even be used underwater as in the case of many stirring purposes. All our ADVANCED LINE stainless steel motors are lubricated with meals grade USDA-H1 grease and can be operated oil-free. A energy discount of approx. 10-20% primarily based on the technical information stated in the product catalog ought to be taken into consideration when designing drives for oil-free operation.
Question: Does an air motor must boast other options for such applications?
Answer: Yes. In many applications, condensation can type in air supply traces. It is subsequently advisable that measures are taken to make certain that the motor is not located on the lowest level in the system and that it may be flushed out with water. Many users take precautionary measures, not only regarding the structure of the motor of their system, but also regarding the utilization of water separators or dryers in entrance of the drive. If all this isn’t potential, then we suggest a special coating for these elements within the motor’s inside which are created from stainless steel. This is as a outcome of there’s a limit to using stainless-steel for heavy responsibility, high-speed internal parts. This so-called CWL coating supplies insensitivity to corrosion.
Question: Do you may have any examples of the place your motors can be utilized within the food industry?
Answer: Stirring dough, transferring and slicing sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals trade applications are endless. I’ll describe a couple of purposes in more element, 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 at the pace of seven hundred rpm.
We even have the ideal drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power in the smallest of spaces. The 900W high-torque motor with a nominal pace of 22 rpm overcomes a beginning torque of 585 Nm and has a most diameter of sixty three mm.
Another software can be present in grinding mills and conveying methods for grain processing. In this case, the main focus is on mud era and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in probably 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 wood skewer via items of meat, onion and pepper. Pressure at the skewer is 38 kg and subsequently a high-power air motor with compact design is ideally suited to this software.
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 principle advantages is its high energy density. Depending on the design, an air motor has solely a fifth of the mass of an electric motor, or a 3rd of its dimension. This is particularly important when utilizing a handheld device however after all also for robotic methods the place the drive strikes with the robotic arm.
Heat also leaves the air motor chilly. In crucial settings, compressed air is an unproblematic supply of vitality – it does not evaluate to the dangers of electrical energy. The energy output from the air motor over extensive torque ranges is type of fixed. Air motors can due to this fact be optimally operated in a large subject of fluctuating masses. There is no problem with load being applied on the air motor until standstill, no damages are incurred. This means it’s much less apt to stalling. After discount of the load, it will run again instantly and any variety of successive instances. Air motor energy may be adapted simply by adjusting the operating strain. The speed is reduced easily by throttling the air quantity. Throttling supply air is really helpful when torque should also be considerably reduced. Exhaust air throttling must be chosen to reduce pace with none severe influence on the torque.
Question: Air motors are sometimes seen to be less environment friendly compared to electric motors. Can you touch upon this statement?
Answer: Air motors and electrical motors cannot be in contrast on a one-to-one basis. The effectivity of a drive all the time is dependent upon the situations of the application. Let me use this example to explain: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is applied at reduced pace over a long time period to secure the packaging tape. Electric motors can’t be loaded over a long time frame with out operating the danger of overheating. Therefore, for this packaging machine, an electrical motor would need to resist excessive loads and as a result would must 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 may 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 velocity at 450 rpm beneath light load. The energy required for this air motor is therefore solely 430W. The vitality stability of an air motor is seen in a completely different mild when you think about that the air motor needed for this packaging machine would solely require a third of the ability of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can mirror on decades of expertise within the area of air motors. They have a broad range of high of the range, globally popular industrial drive solutions. Are the ADVANCED LINE motors a special resolution for food 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 fulfill the needs of our clients. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects benefit from long-established reliable drive options for the meals business and medical technology. We are in a place to provide these motors in a wide energy range from 20 W to 1.6 kW combined with a variety of planetary gears from our own production with speeds of seven to 24,000 rpm.
