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

Automated processes are standard follow in the meals industry. Production efficiency is not the only motivation, hygiene additionally performs a key position within the meals business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss the way to design a drive to meet these necessities and incorporate both these goals.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to ensure that the best drive is chosen to meet the excessive requirements for hygiene in the meals industry, we normally advocate our ADVANCED LINE air vane motors. All their external parts are created from chrome steel and are impervious to regular cleansing agents. The clean surface of these air motors is easy to scrub. The drives are so nicely sealed with durable long-life radial shaft seals that no air can escape and equally no dust, water or other solutions can penetrate the motor. The motors are even immune to water penetration from commonly used cleaning spray systems. A moist setting isn’t any concern for this motor. It may even be used underwater as within the case of many stirring applications. All our ADVANCED LINE stainless steel motors are lubricated with meals grade USDA-H1 grease and can be operated oil-free. A energy reduction of approx. 10-20% based mostly on the technical information stated 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 options for such applications?
Answer: Yes. In many functions, condensation can kind in air supply lines. It is subsequently advisable that measures are taken to make sure that the motor is not situated at the lowest point in the system and that it can be flushed out with water. Many customers take precautionary measures, not solely relating to the format of the motor in their system, but additionally regarding the use of water separators or dryers in front of the drive. If all this is not potential, then we recommend a particular coating for these elements inside the motor’s inside which are created from chrome steel. This is as a end result of there is a restrict to using stainless-steel for heavy obligation, high-speed internal elements. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you could have any examples of where your motors can be utilized in the meals industry?
Answer: Stirring dough, shifting and cutting sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the food industry applications are countless. I’ll describe a number of applications in more detail, such as using 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 requirements 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 starting torque of 585 Nm and has a maximum diameter of sixty three mm.
Another software may be found in grinding mills and conveying techniques for grain processing. In this case, the primary target is on dust technology and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in potentially explosive environments. You will even discover our motors used within the processing of meat, for example 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 gauge น้ำมัน on the skewer is 38 kg and subsequently a high-power air motor with compact design is ideally suited to this application.
Question: What benefits 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 principle advantages is its high power density. Depending on the design, an air motor has solely a fifth of the mass of an electric motor, or a third of its dimension. This is particularly vital when utilizing a handheld device but of course additionally for robotic methods the place the drive strikes with the robot arm.
Heat additionally leaves the air motor cold. In crucial settings, compressed air is an unproblematic supply of vitality – it does not examine to the risks of electricity. The power output from the air motor over extensive torque ranges is nearly constant. Air motors can therefore be optimally operated in a large field of fluctuating loads. There is not any drawback with load being utilized on the air motor until standstill, no damages are incurred. This means it’s much less apt to stalling. After reduction of the load, it’s going to run again immediately and any number of successive instances. Air motor power can be adapted just by adjusting the operating strain. The speed is lowered easily by throttling the air volume. Throttling supply air is recommended when torque also needs to be significantly decreased. Exhaust air throttling should be chosen to reduce velocity without any serious affect on the torque.
Question: Air motors are sometimes seen to be less environment friendly compared to electrical motors. Can you touch upon this statement?
Answer: Air motors and electrical motors can’t be compared on a one-to-one basis. The effectivity of a drive always depends on the circumstances of the applying. Let me use this example to explain: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is utilized at reduced velocity over a protracted time period to secure the packaging tape. Electric motors can’t be loaded over a long time frame without running the chance of overheating. Therefore, for this packaging machine, an electrical motor would want to face up to excessive masses and as a result would need to be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely different story with the air motor: Due to the favourable torque traits of air motors, a lower-powered drive will suffice. You might choose an air motor with a nominal torque of 15 Nm and nominal pace of 275 rpm. Since the working torque is under that of the nominal torque, the air motor runs close to idle pace at 450 rpm beneath gentle load. The energy required for this air motor is subsequently 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 only require a third of the facility of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on a long time of experience within the area of air motors. They have a variety of prime of the range, globally popular industrial drive solutions. Are the ADVANCED LINE motors a particular resolution for food industry applications?
Answer: It is true that our engineers have continued to optimise our air motors over the many years and our commonplace program has been adjusted to fulfill the wants of our clients. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects benefit from long-established reliable drive options for the food industry and medical expertise.
