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

Automated processes are standard apply in the food business. Production efficiency is not the one motivation, hygiene also plays a key position within the meals trade. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate how to design a drive to fulfill these necessities and incorporate both these objectives.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to ensure that the proper drive is selected to fulfill the excessive requirements for hygiene in the meals business, we normally recommend our ADVANCED LINE air vane motors. All their external parts are produced from stainless-steel and are impervious to normal cleaning agents. The easy surface of these air motors is straightforward to scrub. The drives are so well sealed with sturdy long-life radial shaft seals that no air can escape and equally no dust, water or different solutions can penetrate the motor. The motors are even resistant to water penetration from generally used cleansing spray methods. A wet surroundings is no concern for this motor. It can even be used underwater as in the case of many stirring applications. 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% based mostly on the technical data stated in the product catalog must be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor have to boast other features for such applications?
Answer: Yes. In many applications, condensation can type in air provide traces. It is due to this fact advisable that measures are taken to ensure that the motor is not positioned at the lowest point in the system and that it could be flushed out with water. Many customers take precautionary measures, not solely referring to the structure of the motor in their system, but additionally regarding the usage of water separators or dryers in front of the drive. If all this isn’t attainable, then we advocate a special coating for these components inside the motor’s inside which are produced from stainless-steel. This is as a result of there’s a restrict to the use of stainless steel for heavy responsibility, high-speed inner parts. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you may have any examples of where your motors can be utilized within the food industry?
Answer: Stirring dough, transferring and chopping sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals trade purposes are endless. I’ll describe a number of functions in more element, such as the use of our ADVANCED LINE air motor in an agitator for the production 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 perfect drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power in the smallest of areas. The 900W high-torque motor with a nominal velocity of 22 rpm overcomes a beginning torque of 585 Nm and has a maximum diameter of sixty three mm.
Another software may be present in grinding mills and conveying systems for grain processing. In this case, the focus is on dust generation 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 in 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 application.
Question: What benefits does an air motor have over an electrical motor in such applications?
เกจวัดแรงดันเบนซิน : There are many arguments in favour of utilizing 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 third of its size. This is particularly important when using a handheld system however after all also for robotic methods the place the drive moves with the robot arm.
Heat also leaves the air motor chilly. In critical settings, compressed air is an unproblematic source of power – it doesn’t examine to the risks of electricity. The power output from the air motor over broad torque ranges is nearly fixed. Air motors can due to this fact be optimally operated in a large field of fluctuating masses. There is no downside with load being utilized 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 immediately and any number of successive times. Air motor power may be tailored just by adjusting the working pressure. The pace is decreased smoothly by throttling the air quantity. Throttling provide air is recommended when torque must also be significantly reduced. Exhaust air throttling should be chosen to scale back velocity with none severe influence on the torque.
Question: Air motors are sometimes seen to be much less environment friendly compared to electric motors. Can you comment on this statement?
Answer: Air motors and electric motors cannot be compared on a one-to-one basis. เกจวัดแรงดันแก๊สlpg of a drive at all times is decided by the situations of the applying. 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 utilized at reduced pace over a long time frame to safe the packaging tape. Electric motors cannot be loaded over an extended period of time with out working the danger of overheating. Therefore, for this packaging machine, an electric motor would wish to face up to excessive loads and consequently would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally totally 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 close to idle pace at 450 rpm under mild load. The power required for this air motor is therefore solely 430W. The energy steadiness of an air motor is seen in a completely totally different light when you assume about that the air motor needed 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 experience within the field of air motors. They have a variety of top quality, globally in style industrial drive solutions. Are the ADVANCED LINE motors a special answer for meals trade applications?
Answer: It is true that our engineers have continued to optimise our air motors over the many years and our normal program has been adjusted to fulfill the wants of our customers.
