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

Automated processes are commonplace practice in the food business. Production efficiency just isn’t the one motivation, hygiene additionally plays a key role in the meals business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate the means to design a drive to fulfill these requirements and incorporate each these objectives.
Question: How are excessive requirements of hygiene met by DEPRAG?
Answer: In order to ensure that the best drive is chosen to satisfy the excessive requirements for hygiene in the food industry, we often suggest our ADVANCED LINE air vane motors. All their exterior parts are made 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 filth, water or different options can penetrate the motor. The motors are even resistant to water penetration from generally used cleansing spray systems. A wet setting isn’t any concern for this motor. It can even be used underwater as in the case of many stirring functions. All our ADVANCED LINE chrome steel motors are lubricated with food grade USDA-H1 grease and can be operated oil-free. A power reduction of approx. 10-20% primarily based on the technical information stated within the product catalog should be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor have to boast other options for such applications?
Answer: Yes. In many applications, 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 at the lowest point within the system and that it could be flushed out with water. Many customers take precautionary measures, not only regarding the format of the motor of their system, but also regarding the utilization of water separators or dryers in entrance of the drive. If all this is not attainable, then we suggest a special coating for these elements within the motor’s inside which are made from chrome steel. This is as a outcome of there is a restrict to the usage of stainless steel for heavy duty, high-speed inner elements. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you could have any examples of the place your motors can be used within the meals industry?
Answer: Stirring dough, moving and cutting sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals trade functions are infinite. I’ll describe a couple of functions in additional detail, such as 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 on the velocity of seven hundred rpm.
We also 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 velocity of twenty-two 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 major target is on dust technology and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in probably explosive environments. You will even discover our motors used within 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 by way of 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 utility.
Question: What advantages does an air motor have over an electric motor in such applications?
Answer: There are many arguments in favour of utilizing an air motor: One of the principle benefits is its excessive energy density. Depending on the design, an air motor has solely a fifth of the mass of an electrical motor, or a 3rd of its measurement. This is particularly significant when using a handheld gadget however of course also for robotic methods the place the drive moves with the robot arm.
Heat additionally leaves the air motor cold. In crucial settings, compressed air is an unproblematic supply of vitality – it does not compare to the risks of electricity. The power output from the air motor over extensive torque ranges is nearly constant. Air motors can subsequently be optimally operated in a wide field of fluctuating loads. There isn’t any drawback with load being applied on the air motor till standstill, no damages are incurred. This means it’s less apt to stalling. After reduction of the load, it will run once more immediately and any variety of successive times. Air motor energy may be adapted simply by adjusting the working pressure. The pace is reduced easily by throttling the air volume. Throttling provide air is really helpful when torque should also be considerably decreased. Exhaust air throttling should be chosen to minimize back speed without any critical influence on the torque.
Question: Air motors are often seen to be less efficient in comparison with electrical motors. Can you touch upon this statement?
Answer: Air motors and electrical motors cannot be compared on a one-to-one basis. The effectivity of a drive all the time depends on the situations of the application. 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 applied at lowered pace over an extended time frame to secure the packaging tape. เกจวัดแรงดัน300psi cannot be loaded over a protracted period of time without working the chance of overheating. Therefore, for this packaging machine, an electric motor would want to resist excessive hundreds and as a result would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely completely different story with the air motor: Due to the beneficial 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 speed of 275 rpm. Since the working torque is under that of the nominal torque, the air motor runs close to idle speed at 450 rpm beneath light load. The energy required for this air motor is subsequently solely 430W. The vitality steadiness of an air motor is seen in a very totally different light when you assume 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 replicate on a long time of experience within the area of air motors. They have a wide range of excessive quality, globally in style industrial drive solutions. Are the ADVANCED LINE motors a special solution for food trade applications?
Answer: It is true that our engineers have continued to optimise our air motors over the decades and our normal program has been adjusted to meet the needs of our clients. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects profit from long-established reliable drive solutions for the food industry and medical know-how. We are in a position to supply these motors in a wide energy range from 20 W to 1.6 kW mixed with quite so much of planetary gears from our own manufacturing with speeds of seven to 24,000 rpm.
