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

Automated processes are standard apply within the food business. Production effectivity isn’t the only motivation, hygiene additionally plays a key position in the food business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss tips on how to design a drive to meet these necessities and incorporate both these targets.
Question: How are high requirements of hygiene met by DEPRAG?
Answer: In order to make sure that the right drive is chosen to meet the high necessities for hygiene within the meals industry, we often recommend our ADVANCED LINE air vane motors. All their external elements are created from stainless steel and are impervious to regular cleaning agents. The clean floor of these air motors is simple to clean. 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 options can penetrate the motor. The motors are even resistant to water penetration from generally used cleansing spray techniques. A wet setting 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 food grade USDA-H1 grease and may be operated oil-free. A energy discount of approx. 10-20% primarily based on the technical data said in the product catalog must be taken into account 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 form in air supply lines. It is subsequently advisable that measures are taken to make certain that the motor isn’t positioned on the lowest point in the system and that it might be flushed out with water. Many users take precautionary measures, not only referring to the format of the motor in their system, but in addition concerning the utilization of water separators or dryers in entrance of the drive. If all this is not possible, then we advocate a particular coating for these components within the motor’s inside which are produced from chrome steel. เกจวัดแรงดันลมดิจิตอล is because there’s a limit to using stainless-steel for heavy responsibility, high-speed internal components. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you could 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 food trade purposes are endless. I’ll describe a couple of purposes in more detail, such as 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 on the speed of seven-hundred rpm.
We even have the ideal drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy within the smallest of spaces. The 900W high-torque motor with a nominal speed of twenty-two rpm overcomes a beginning torque of 585 Nm and has a maximum diameter of sixty three mm.
Another utility can be present in grinding mills and conveying methods for grain processing. In this case, the focus is on mud 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 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 wooden 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 application.
Question: What advantages 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 primary advantages is its excessive power density. Depending on the design, an air motor has solely a fifth of the mass of an electrical motor, or a 3rd of its measurement. This is particularly vital when using a handheld system but after all also for robotic systems the place the drive strikes with the robotic arm.
Heat also leaves the air motor chilly. In critical settings, compressed air is an unproblematic source of energy – it does not evaluate to the dangers of electrical energy. The power output from the air motor over extensive torque ranges is sort of constant. Air motors can due to this fact be optimally operated in a wide area of fluctuating masses. There isn’t any problem with load being applied on the air motor until standstill, no damages are incurred. This means it is much less apt to stalling. After reduction of the load, it’ll run again instantly and any variety of successive times. Air motor energy may be adapted simply by adjusting the operating strain. The pace is reduced smoothly by throttling the air volume. Throttling provide air is really helpful when torque should also be significantly decreased. Exhaust air throttling ought to be chosen to reduce speed with none severe affect on the torque.
Question: Air motors are often seen to be less environment friendly in comparability with electric motors. Can you touch upon this statement?
Answer: Air motors and electric motors can’t be in contrast on a one-to-one foundation. The effectivity of a drive at all times is dependent upon the situations of the appliance. Let me use this example 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 safe the packaging tape. Electric motors cannot be loaded over an extended time frame without running the danger of overheating. Therefore, for this packaging machine, an electric motor would need to resist high loads and in consequence would need to be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally totally different story with the air motor: Due to the beneficial torque traits of air motors, a lower-powered drive will suffice. You might select an air motor with a nominal torque of 15 Nm and nominal speed of 275 rpm. Since the working torque is below that of the nominal torque, the air motor runs close to idle pace at 450 rpm beneath mild load. The energy required for this air motor is due to this fact only 430W. The power steadiness of an air motor is seen in a totally completely different light when you consider that the air motor wanted for this packaging machine would only require a 3rd of the ability of an electric 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 popular industrial drive solutions. Are the ADVANCED LINE motors a particular solution 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 fulfill the wants of our prospects. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our clients benefit from long-established dependable drive options for the food business and medical expertise.
