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

Automated processes are normal follow in the meals industry. Production effectivity isn’t the one motivation, hygiene additionally plays a key position 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 meet these requirements and incorporate each these goals.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to make certain that the best drive is chosen to satisfy the excessive necessities for hygiene within the meals trade, we often advocate our ADVANCED LINE air vane motors. All their exterior elements are produced from stainless steel and are impervious to regular cleansing brokers. The easy floor of those air motors is simple to clean. The drives are so nicely sealed with sturdy long-life radial shaft seals that no air can escape and equally no filth, water or different solutions can penetrate the motor. The motors are even proof against water penetration from commonly used cleaning spray systems. A wet surroundings is no concern for this motor. It can even be used underwater as within the case of many stirring purposes. All our ADVANCED LINE stainless steel motors are lubricated with food grade USDA-H1 grease and could be operated oil-free. A energy reduction of approx. 10-20% based mostly on the technical information stated within the product catalog must 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 type in air provide traces. It is therefore advisable that measures are taken to make certain that the motor is not positioned on 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 in their system, but also regarding the use of water separators or dryers in entrance of the drive. If all this is not potential, then we suggest a particular coating for those elements within the motor’s interior which are created from chrome steel. This is as a result of there’s a restrict to the use of stainless-steel for heavy obligation, high-speed inner components. This so-called CWL coating supplies insensitivity to corrosion.
Question: Do you’ve any examples of where your motors can be used within the food industry?
Answer: Stirring dough, shifting and chopping sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals business functions are endless. I’ll describe a few purposes in more detail, similar to using 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 speed of 700 rpm.
We even have the best drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy in 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 utility could be present in grinding mills and conveying methods for grain processing. In this case, the primary focus is on dust generation and explosion prevention. All our ADVANCED LINE motors are ATEX licensed for use in probably explosive environments. You will even find our motors used within 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 picket skewer by way of items 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 software.
Question: What advantages does an air motor have over an electric motor in such applications?
Answer: There are many arguments in favour of using an air motor: One of the main advantages is its high energy density. Depending on the design, an air motor has only a fifth of the mass of an electrical motor, or a third of its size. This is especially important when using a handheld gadget however in fact additionally for robotic methods where the drive moves with the robotic arm.
Heat also leaves the air motor cold. In important settings, compressed air is an unproblematic source of energy – it doesn’t evaluate to the dangers of electricity. The power output from the air motor over wide torque ranges is nearly fixed. Air motors can due to this fact be optimally operated in a large field of fluctuating masses. There is not any downside 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’s going to run again immediately and any number of successive instances. Air motor energy could be tailored simply by adjusting the operating strain. pressure gauge ดิจิตอล is lowered smoothly by throttling the air volume. Throttling provide air is really helpful when torque also wants to be significantly decreased. Exhaust air throttling should be chosen to scale back velocity with none critical influence on the torque.
Question: Air motors are often seen to be less environment friendly in comparison with electric motors. Can you touch upon this statement?
Answer: Air motors and electrical motors cannot be compared on a one-to-one foundation. The efficiency of a drive at all times is decided by the conditions of the appliance. 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 utilized at reduced pace over a protracted period of time to safe the packaging tape. Electric motors cannot be loaded over a protracted time frame without running the risk of overheating. Therefore, for this packaging machine, an electrical motor would wish to resist excessive loads and as a result would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a very completely different story with the air motor: Due to the beneficial torque traits of air motors, a lower-powered drive will suffice. You may choose an air motor with a nominal torque of 15 Nm and nominal pace of 275 rpm. Since the working torque is below that of the nominal torque, the air motor runs near idle speed at 450 rpm under light load. The energy required for this air motor is therefore solely 430W. The vitality stability of an air motor is seen in a very completely different light when you assume about that the air motor wanted for this packaging machine would only require a 3rd of the ability of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can mirror on a long time of expertise within the field of air motors. They have a wide range of prime quality, globally in style industrial drive solutions. 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 commonplace program has been adjusted to satisfy the needs of our prospects. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects profit from long-established dependable drive options for the food trade and medical technology. We are able to provide these motors in a large energy vary from 20 W to 1.6 kW mixed with a variety of planetary gears from our personal production with speeds of seven to 24,000 rpm. pressure gauge ไฮ ด รอ ลิ ค of chrome steel motors has made us a market leader in this segment.
