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

Automated processes are standard apply within the food business. Production efficiency isn’t the only motivation, hygiene also performs a key function within the meals industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss tips on how to design a drive to satisfy these requirements and incorporate both these goals.
Question: How are excessive standards of hygiene met by DEPRAG?
Answer: In order to ensure that the best drive is selected to meet the high requirements for hygiene in the meals industry, we usually suggest our ADVANCED LINE air vane motors. All their external parts are created from stainless steel and are impervious to normal cleansing agents. The clean surface of these air motors is straightforward to scrub. The drives are so properly 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 generally used cleaning spray methods. A wet environment isn’t any concern for this motor. It may even be used underwater as within the case of many stirring purposes. All our ADVANCED LINE stainless steel motors are lubricated with meals grade USDA-H1 grease and may be operated oil-free. A energy discount of approx. 10-20% based mostly on the technical data stated in the product catalog ought to be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor must boast other features for such applications?
Answer: Yes. In many applications, condensation can type in air provide lines. It is subsequently advisable that measures are taken to guarantee that the motor just isn’t positioned on the lowest level in the system and that it could be flushed out with water. Many customers take precautionary measures, not only regarding the layout of the motor in their system, but in addition regarding the usage of water separators or dryers in front of the drive. If all this isn’t potential, then we recommend a special coating for those components throughout the motor’s interior which are produced from stainless steel. This is because there’s a restrict to using stainless-steel for heavy responsibility, high-speed inside parts. 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 food 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 endless. I’ll describe a few functions in more element, corresponding to 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 700 rpm.
We even have the ideal drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power in the smallest of spaces. The 900W high-torque motor with a nominal pace of 22 rpm overcomes a starting torque of 585 Nm and has a most diameter of 63 mm.
Another utility could be present in grinding mills and conveying techniques for grain processing. In เกจวัดแรงดันน้ำมันเบนซิน , the main focus 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 wooden skewer by way of items 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 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 main benefits is its excessive energy density. Depending on the design, an air motor has only a fifth of the mass of an electrical motor, or a 3rd of its dimension. This is especially significant when utilizing a handheld system however after all additionally for robotic techniques where the drive moves with the robotic arm.
Heat additionally leaves the air motor chilly. In important settings, compressed air is an unproblematic source of energy – it does not evaluate to the dangers of electrical energy. The energy output from the air motor over wide torque ranges is almost fixed. Air motors can therefore be optimally operated in a large field of fluctuating masses. There is not any drawback with load being applied on the air motor until standstill, no damages are incurred. This means it is less apt to stalling. After discount of the load, it will run again immediately and any number of successive instances. Air motor power could be adapted just by adjusting the working stress. The speed is decreased easily by throttling the air quantity. Throttling provide air is really helpful when torque should also be significantly lowered. Exhaust air throttling ought to be chosen to scale back velocity without any critical affect on the torque.
Question: Air motors are often seen to be much less efficient compared to electrical motors. Can you touch upon this statement?
Answer: Air motors and electrical motors can’t be in contrast on a one-to-one basis. The efficiency of a drive always is determined by the conditions of the applying. Let me use this instance to elucidate: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is applied at reduced velocity over a long time frame to secure the packaging tape. Electric motors can’t be loaded over a long time period without running the risk of overheating. Therefore, for this packaging machine, an electric motor would wish to face up to high masses and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally different story with the air motor: Due to the beneficial torque characteristics of air motors, a lower-powered drive will suffice. You might 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 near idle speed at 450 rpm underneath gentle load. The energy required for this air motor is therefore solely 430W. The power steadiness of an air motor is seen in a very totally different light when you suppose about that the air motor wanted for this packaging machine would solely require a 3rd of the facility of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on many years of expertise in the field of air motors. They have a broad range of high quality, globally popular industrial drive options. 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 standard program has been adjusted to satisfy the wants of our prospects.
