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

Automated processes are standard apply within the food business. Production effectivity is not the one motivation, hygiene additionally plays a key position in the food industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate how to design a drive to satisfy these necessities and incorporate both these targets.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to guarantee that the proper drive is chosen to satisfy the high requirements for hygiene in the food trade, we often advocate our ADVANCED LINE air vane motors. All their exterior components are made from stainless steel and are impervious to normal cleansing brokers. The easy surface of those air motors is straightforward to wash. The drives are so properly 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 commonly used cleansing spray systems. A wet surroundings isn’t any concern for this motor. It can even be used underwater as within the case of many stirring applications. All our ADVANCED LINE stainless steel motors are lubricated with food grade USDA-H1 grease and may be operated oil-free. A power discount of approx. 10-20% based on the technical knowledge 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 options for such applications?
Answer: Yes. In many applications, condensation can type in air provide strains. It is therefore advisable that measures are taken to ensure that the motor isn’t positioned on the lowest point in the system and that it can be flushed out with water. Many customers take precautionary measures, not only referring to the format of the motor in their system, but additionally concerning the use of water separators or dryers in entrance of the drive. If all this is not potential, then we recommend a special coating for these components inside the motor’s inside which are made from stainless-steel. This is as a end result of there’s a limit to the utilization of chrome steel for heavy duty, high-speed inner 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, moving and chopping sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the food industry purposes are endless. I’ll describe a quantity of purposes in more element, corresponding to 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 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 power within the smallest of areas. The 900W high-torque motor with a nominal velocity of 22 rpm overcomes a beginning torque of 585 Nm and has a most diameter of sixty three mm.
Another application may be found in grinding mills and conveying techniques for grain processing. In this case, the main target is on dust generation and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in potentially explosive environments. You will even discover 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 wood skewer by way of items of meat, onion and pepper. Pressure at the skewer is 38 kg and subsequently a high-power air motor with compact design is ideally suited to this software.
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 benefits 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 third of its size. This is especially important when using a handheld system however of course also for robotic systems where the drive strikes with the robot arm.
Heat also leaves the air motor cold. In critical settings, compressed air is an unproblematic supply of vitality – it doesn’t compare to the risks of electricity. The power output from the air motor over broad torque ranges is nearly constant. Air motors can due to this fact be optimally operated in a large area of fluctuating loads. There isn’t any problem with load being utilized on the air motor until standstill, no damages are incurred. This means it’s less apt to stalling. After discount of the load, it’s going to run once more instantly and any number of successive instances. Air motor power may be tailored simply by adjusting the working stress. The speed is decreased easily by throttling the air volume. Throttling provide air is really helpful when torque also needs to be significantly lowered. Exhaust air throttling ought to be chosen to reduce pace without any serious affect on the torque.
Question: Air motors are often seen to be less environment friendly compared to electrical motors. Can you touch upon this statement?
Answer: Air motors and electric motors can’t be compared on a one-to-one basis. The efficiency of a drive always is determined by the circumstances of the application. Let me use this instance 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 long time period to safe the packaging tape. Electric motors cannot be loaded over a long time frame with out operating the danger of overheating. Therefore, for this packaging machine, an electric motor would need to face up to high loads and consequently would need to be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely totally different story with the air motor: Due to the beneficial torque traits of air motors, a lower-powered drive will suffice. You could select an air motor with a nominal torque of 15 Nm and nominal speed of 275 rpm. Since the working torque is beneath that of the nominal torque, the air motor runs close to idle velocity at 450 rpm underneath mild load. The power required for this air motor is therefore solely 430W. The vitality stability of an air motor is seen in a completely completely different gentle when you consider that the air motor needed for this packaging machine would only require a third of the ability of an electric motor.
เกจวัดแรงดันน้ำ4หุน : DEPRAG SCHULZ GMBH u. CO. can reflect on a long time of expertise within the area of air motors. They have a broad range of prime quality, globally well-liked industrial drive options. Are the ADVANCED LINE motors a special resolution for meals industry applications?
