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

Automated processes are commonplace practice in the food business. Production efficiency just isn’t the one motivation, hygiene also plays a key role in the food trade. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate tips on how to design a drive to fulfill these necessities and incorporate both these goals.
Question: How are high requirements of hygiene met by DEPRAG?
Answer: In order to ensure that the right drive is chosen to satisfy the excessive requirements for hygiene within the meals business, we often suggest our ADVANCED LINE air vane motors. All their exterior parts are made from stainless-steel and are impervious to regular cleansing brokers. The clean floor of those 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 filth, water or different options can penetrate the motor. The motors are even resistant to water penetration from commonly used cleansing spray methods. A moist setting is not any concern for this motor. It may even be used underwater as in the case of many stirring applications. pressure gauge ไท วัสดุ -steel motors are lubricated with meals grade USDA-H1 grease and could be operated oil-free. A power reduction of approx. 10-20% based mostly on the technical data stated within the product catalog should be taken into consideration when designing drives for oil-free operation.
Question: Does an air motor must boast other features for such applications?
Answer: Yes. In many purposes, condensation can kind in air provide lines. It is due to this fact advisable that measures are taken to ensure that the motor is not positioned at the lowest level within the system and that it can be flushed out with water. Many customers take precautionary measures, not solely referring to the structure of the motor of their system, but in addition regarding the usage of water separators or dryers in entrance of the drive. If all this is not potential, then we recommend a particular coating for those parts inside the motor’s inside which are made from chrome steel. This is as a end result of there’s a limit to the use of stainless-steel for heavy duty, high-speed inside parts. This so-called CWL coating supplies insensitivity to corrosion.
Question: Do you have any examples of the place your motors can be used within the meals industry?
Answer: Stirring dough, moving and chopping sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the food trade purposes are infinite. I’ll describe a couple of applications in more element, similar 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 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 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 software could be present in grinding mills and conveying techniques for grain processing. In this case, the focus is on dust era and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in probably explosive environments. You will even discover 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 wooden skewer by way of pieces 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 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 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 size. This is especially significant when using a handheld system however of course additionally for robotic techniques the place the drive moves with the robot arm.
Heat also leaves the air motor chilly. In crucial settings, compressed air is an unproblematic source of energy – it doesn’t examine to the dangers of electricity. The power output from the air motor over wide torque ranges is nearly fixed. Air motors can due to this fact be optimally operated in a large subject of fluctuating loads. There is no downside with load being utilized on the air motor until standstill, no damages are incurred. This means it is less apt to stalling. After discount of the load, it’s going to run again instantly and any variety of successive times. Air motor power could be adapted just by adjusting the working stress. The speed is reduced smoothly by throttling the air quantity. Throttling supply air is beneficial when torque must also be significantly lowered. Exhaust air throttling should be chosen to scale back pace with none serious influence on the torque.
Question: Air motors are often seen to be less efficient in comparison 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 basis. The effectivity of a drive at all times depends on the conditions 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 decreased velocity over a protracted time frame to secure the packaging tape. Electric motors can’t be loaded over a long time period with out working the danger of overheating. Therefore, for this packaging machine, an electrical motor would need to withstand excessive masses and as a result would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely completely different story with the air motor: Due to the favourable torque traits of air motors, a lower-powered drive will suffice. You may 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 velocity at 450 rpm under gentle load. The energy required for this air motor is subsequently solely 430W. The energy stability of an air motor is seen in a completely totally different gentle when you suppose about that the air motor wanted for this packaging machine would solely require a 3rd of the facility of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on a long time of experience within the subject of air motors. They have a extensive range of top quality, 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 a long time and our normal program has been adjusted to meet the needs of our customers.
