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

Automated processes are standard apply in the food trade. Production effectivity is not the one motivation, hygiene also performs a key role within the food trade. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate the means 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 best drive is selected to satisfy the high necessities for hygiene within the food business, we often suggest our ADVANCED LINE air vane motors. All their external parts are created from stainless steel and are impervious to regular cleaning agents. The smooth floor of those air motors is easy to scrub. 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 solutions 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 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% based mostly on the technical data acknowledged in the product catalog ought to be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor need to boast other options for such applications?
Answer: Yes. In many purposes, condensation can kind in air provide lines. It is subsequently advisable that measures are taken to guarantee that the motor is not situated at the lowest level in the system and that it could be flushed out with water. Many customers take precautionary measures, not solely relating to the layout of the motor of their system, but also regarding the usage of water separators or dryers in entrance of the drive. If all this is not attainable, then we recommend a special coating for those parts within the motor’s inside that are made from stainless-steel. This is as a end result of there is a limit to the use of stainless-steel for heavy duty, high-speed inner parts. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you have any examples of where your motors can be used in the food industry?
Answer: Stirring dough, transferring and chopping sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals trade purposes are infinite. I’ll describe a quantity of applications in more detail, such as the usage 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 also have the best drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power within the smallest of spaces. The 900W high-torque motor with a nominal speed of 22 rpm overcomes a beginning torque of 585 Nm and has a most diameter of 63 mm.
Another software can be present in grinding mills and conveying methods for grain processing. In this case, the primary target is on dust generation and explosion prevention. All our ADVANCED LINE motors are ATEX certified to be used in doubtlessly explosive environments. You will even find our motors used in the processing of meat, for instance 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 wooden skewer via pieces of meat, onion and pepper. Pressure at 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?
Answer: 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 electrical motor, or a third of its measurement. This is especially significant when utilizing a handheld system however after all additionally for robotic systems the place the drive moves with the robot arm.
Heat also leaves the air motor chilly. In important settings, compressed air is an unproblematic source of vitality – it does not examine to the hazards of electricity. The energy output from the air motor over extensive torque ranges is nearly fixed. Air motors can subsequently be optimally operated in a wide area of fluctuating hundreds. There isn’t any problem with load being utilized on the air motor until standstill, no damages are incurred. This means it is less apt to stalling. After discount of the load, it’s going to run once more instantly and any variety of successive occasions. Air motor energy may be adapted simply by adjusting the working strain. The speed is decreased smoothly by throttling the air volume. Throttling supply air is recommended when torque also needs to be considerably lowered. Exhaust air throttling should be chosen to minimize back velocity without any critical affect on the torque.
Question: Air motors are sometimes seen to be much less environment friendly compared to electrical motors. Can you comment on this statement?
Answer: Air motors and electric motors cannot be compared on a one-to-one basis. The efficiency of a drive all the time is dependent upon the circumstances of the applying. 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 utilized at decreased pace over a protracted time period to secure the packaging tape. Electric motors cannot be loaded over a protracted time frame without operating the chance of overheating. Therefore, for this packaging machine, an electrical motor would want to withstand high hundreds and as a result would need 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 favourable torque traits of air motors, a lower-powered drive will suffice. Privy may 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 near idle speed at 450 rpm beneath light load. The power required for this air motor is due to this fact solely 430W. The energy stability of an air motor is seen in a totally completely different mild when you consider 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 mirror on many years of experience in the subject of air motors. They have a variety of high quality, globally in style industrial drive options. Are the ADVANCED LINE motors a special solution for meals business applications?
Answer: It is true that our engineers have continued to optimise our air motors over the a long time and our commonplace program has been adjusted to meet the needs of our clients.
