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

Automated processes are standard apply within the meals business. Production effectivity just isn’t the only motivation, hygiene additionally performs a key function within the food industry. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to discuss the method to design a drive to satisfy these requirements and incorporate each these goals.
Question: How are high requirements of hygiene met by DEPRAG?
Answer: In order to ensure that the best drive is selected to satisfy the high requirements for hygiene within the food trade, we often advocate our ADVANCED LINE air vane motors. All their external elements are produced from stainless steel and are impervious to regular cleaning agents. The easy floor of these air motors is simple to clean. The drives are so nicely 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 immune to water penetration from commonly used cleansing spray systems. A wet setting is no concern for this motor. It may even be used underwater as within the case of many stirring applications. All our ADVANCED LINE chrome steel motors are lubricated with meals grade USDA-H1 grease and can be operated oil-free. A power reduction of approx. 10-20% primarily based 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 functions, condensation can kind in air provide strains. It is due to this fact advisable that measures are taken to make sure that the motor is not situated at the lowest level in the system and that it may be flushed out with water. Many users take precautionary measures, not only relating to the structure of the motor of their system, but also concerning using water separators or dryers in entrance of the drive. If all this is not potential, then we suggest a special coating for those elements throughout the motor’s inside which are made from stainless-steel. This is because there’s a restrict to using chrome steel for heavy obligation, high-speed inside components. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you may have any examples of where your motors can be used in the food industry?
Answer: Stirring dough, moving and chopping sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals trade purposes are infinite. I’ll describe a few functions in more element, similar to the use 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 velocity of seven-hundred 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 areas. The 900W high-torque motor with a nominal speed of twenty-two rpm overcomes a starting torque of 585 Nm and has a most diameter of 63 mm.
Another application could be found in grinding mills and conveying methods for grain processing. In this case, the major focus is on mud generation and explosion prevention. All our ADVANCED LINE motors are ATEX licensed for use in doubtlessly explosive environments. You will even find our motors used in 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 wood skewer by way of items of meat, onion and pepper. Pressure on the skewer is 38 kg and subsequently a high-power air motor with compact design is ideally suited to this software.
Question: What benefits does an air motor have over an electrical motor in such applications?
Answer: There are many arguments in favour of using an air motor: One of the main advantages is its excessive energy density. Depending on the design, an air motor has solely a fifth of the mass of an electrical motor, or a third of its dimension. เพรสเชอร์เกจลม is especially vital when using a handheld system but of course also for robotic techniques where the drive moves with the robotic arm.
Heat additionally leaves the air motor cold. In crucial settings, compressed air is an unproblematic supply of energy – it does not compare to the risks of electrical energy. The energy output from the air motor over wide torque ranges is nearly constant. Air motors can subsequently be optimally operated in a large field of fluctuating loads. There isn’t any drawback with load being utilized on the air motor till standstill, no damages are incurred. This means it’s less apt to stalling. After discount of the load, it’s going to run again instantly and any variety of successive instances. Air motor power may be adapted simply by adjusting the working stress. The pace is decreased smoothly by throttling the air quantity. Throttling provide air is recommended when torque must also be significantly decreased. Exhaust air throttling ought to be chosen to cut back velocity with none serious affect on the torque.
Question: Air motors are sometimes seen to be less environment friendly compared to electrical motors. Can you comment on this statement?
Answer: Air motors and electric motors cannot be compared on a one-to-one basis. The effectivity of a drive always is dependent upon the conditions of the application. Let เกจวัดแก๊สlpg use this instance to clarify: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is applied at lowered velocity over an extended time period to safe the packaging tape. Electric motors can’t be loaded over a protracted time period without operating the risk of overheating. Therefore, for this packaging machine, an electrical motor would wish to resist high masses and consequently would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally completely 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 beneath that of the nominal torque, the air motor runs close to idle speed at 450 rpm underneath gentle load. The energy required for this air motor is therefore only 430W. The energy steadiness of an air motor is seen in a very completely different gentle when you consider that the air motor wanted for this packaging machine would only require a third of the ability of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on decades of expertise within the field of air motors. They have a variety of prime of the range, globally in style industrial drive options. Are the ADVANCED LINE motors a particular resolution for meals industry applications?
Answer: It is true that our engineers have continued to optimise our air motors over the decades and our normal program has been adjusted to fulfill the needs of our customers. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our clients benefit from long-established reliable drive solutions for the food business and medical technology.
