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

Automated processes are commonplace practice in the food business. Production effectivity just isn’t the one motivation, hygiene additionally plays a key role in the meals trade. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate the means to design a drive to meet these necessities and incorporate both these goals.
Question: How are excessive standards of hygiene met by DEPRAG?

Answer: In order to make certain that the best drive is selected to satisfy the excessive requirements for hygiene in the food business, we often suggest our ADVANCED LINE air vane motors. All their exterior elements are created from chrome steel and are impervious to regular cleaning agents. The clean surface of these air motors is easy to wash. The drives are so nicely sealed with durable 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 immune to water penetration from commonly used cleansing spray methods. A moist surroundings isn’t any concern for this motor. It may even be used underwater as within the case of many stirring functions. 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 acknowledged within the product catalog ought to be taken into consideration when designing drives for oil-free operation.
Question: Does an air motor need to boast other features for such applications?

Answer: Yes. In many applications, condensation can kind in air supply strains. It is due to this fact advisable that measures are taken to make sure that the motor just isn’t situated at the lowest level in the system and that it can be flushed out with water. digital pressure gauge take precautionary measures, not solely relating to the structure of the motor of their system, but additionally regarding using water separators or dryers in front of the drive. If all this isn’t possible, then we recommend a particular coating for those components inside the motor’s interior that are created from chrome steel. pressure gauge 10 bar is as a end result of there’s a restrict to using 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 in the meals industry?

Answer: Stirring dough, transferring and chopping sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals business functions are infinite. I’ll describe a couple of purposes in more element, corresponding to the utilization 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 velocity of 700 rpm.
We even have the best drive for high-torque necessities 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 speed of twenty-two rpm overcomes a starting torque of 585 Nm and has a most diameter of sixty three mm.
Another software can 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 find our motors used in 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 picket 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 benefits 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 main benefits is its excessive power density. Depending on the design, an air motor has only a fifth of the mass of an electric motor, or a third of its measurement. This is particularly vital when using a handheld system but of course additionally for robotic systems the place the drive strikes with the robot arm.
Heat additionally leaves the air motor chilly. In crucial settings, compressed air is an unproblematic supply of power – it does not compare to the dangers of electricity. The energy output from the air motor over extensive torque ranges is type of constant. Air motors can therefore be optimally operated in a wide field of fluctuating loads. There is not any downside with load being applied on the air motor till standstill, no damages are incurred. This means it’s much less apt to stalling. After reduction of the load, it’s going to run once more immediately and any number of successive instances. Air motor energy may be tailored just by adjusting the operating pressure. The velocity is decreased smoothly by throttling the air volume. Throttling provide air is beneficial when torque should also be considerably lowered. Exhaust air throttling ought to be chosen to cut back velocity with none severe influence on the torque.
Question: Air motors are often seen to be less environment friendly compared to electrical 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 always depends on the situations of the appliance. Let me use this example to elucidate: 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 period to secure the packaging tape. Electric motors cannot be loaded over an extended time frame without working the chance of overheating. Therefore, for this packaging machine, an electrical motor would need to face up to excessive loads and in consequence would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally completely different story with the air motor: Due to the favourable torque characteristics of air motors, a lower-powered drive will suffice. You could select an air motor with a nominal torque of 15 Nm and nominal velocity of 275 rpm. Since the working torque is beneath that of the nominal torque, the air motor runs close to idle speed at 450 rpm beneath gentle load. The energy required for this air motor is therefore solely 430W. The vitality steadiness of an air motor is seen in a very completely different gentle when you suppose about that the air motor wanted for this packaging machine would only require a third of the power of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on decades of experience in the area of air motors. They have a variety of prime quality, globally well-liked industrial drive options. Are the ADVANCED LINE motors a particular resolution for meals trade applications?

Answer: It is true that our engineers have continued to optimise our air motors over the a long time and our standard program has been adjusted to meet the needs of our customers. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects benefit from long-established reliable drive options for the food trade and medical know-how. We are able to supply these motors in a wide energy range from 20 W to 1.6 kW mixed with a wide range of planetary gears from our own manufacturing with speeds of seven to 24,000 rpm.
