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

Automated processes are standard practice within the meals industry. Production effectivity is not the one motivation, hygiene also performs a key role in the food business. เกจวัดแรงดันภาษาอังกฤษ met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate tips on how to design a drive to satisfy these necessities and incorporate both these goals.
Question: How are high requirements of hygiene met by DEPRAG?
Answer: In order to guarantee that the proper drive is chosen to satisfy the excessive necessities for hygiene in the food trade, we usually advocate our ADVANCED LINE air vane motors. All their exterior elements are made from stainless steel and are impervious to regular cleaning agents. The clean surface of those air motors is simple to wash. The drives are so well sealed with sturdy long-life radial shaft seals that no air can escape and equally no dirt, water or different options can penetrate the motor. The motors are even resistant to water penetration from commonly used cleaning spray methods. A wet surroundings is not any concern for this motor. It can even be used underwater as in the case of many stirring applications. All our ADVANCED LINE stainless steel motors are lubricated with meals grade USDA-H1 grease and may be operated oil-free. A energy reduction of approx. 10-20% primarily based on the technical knowledge acknowledged within the product catalog must be taken under 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 form in air provide strains. It is therefore advisable that measures are taken to ensure that the motor just isn’t positioned at the lowest level within the system and that it may be flushed out with water. Many users take precautionary measures, not solely relating to the layout of the motor in their system, but in addition concerning using water separators or dryers in entrance of the drive. If all this isn’t potential, then we advocate a particular coating for those elements within the motor’s interior which are created from stainless steel. This is as a outcome of there is a restrict to the use of stainless steel for heavy obligation, high-speed inside parts. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you have any examples of the place your motors can be used in the food industry?
Answer: Stirring dough, shifting and cutting sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the food trade applications are countless. I’ll describe a couple of purposes in more element, similar to the usage 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 at the velocity of seven hundred rpm.
We also have the best 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 pace of twenty-two rpm overcomes a starting torque of 585 Nm and has a most diameter of sixty three mm.
Another software may be present in grinding mills and conveying methods for grain processing. In this case, the major focus is on mud era and explosion prevention. All our ADVANCED LINE motors are ATEX certified for use in doubtlessly explosive environments. You will even find 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 picket skewer via items of meat, onion and pepper. Pressure at the skewer is 38 kg and due to this fact a high-power air motor with compact design is ideally suited to this utility.
Question: What advantages does an air motor have over an electric motor in such applications?
Answer: There are many arguments in favour of using an air motor: One of the principle benefits is its high energy density. Depending on the design, an air motor has solely a fifth of the mass of an electric motor, or a third of its size. This is especially significant when utilizing a handheld system however of course additionally for robotic methods where the drive strikes with the robot arm.
Heat additionally leaves the air motor chilly. In critical settings, compressed air is an unproblematic source of vitality – it doesn’t examine to the risks of electrical energy. The energy output from the air motor over extensive torque ranges is sort of fixed. Air motors can subsequently be optimally operated in a wide field of fluctuating hundreds. There isn’t any downside 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 immediately and any number of successive instances. Air motor energy may be adapted simply by adjusting the working strain. The speed is decreased smoothly by throttling the air volume. Throttling provide ชนิดของpressuregauge is beneficial when torque also needs to be significantly decreased. Exhaust air throttling should be chosen to cut back velocity with none serious influence 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 electrical motors cannot be in contrast on a one-to-one foundation. The efficiency of a drive always depends on the conditions of the applying. Let me use this instance to elucidate: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is utilized at decreased speed over an extended time frame to safe the packaging tape. Electric motors cannot be loaded over a protracted time frame with out running the chance of overheating. Therefore, for this packaging machine, an electric motor would need to resist high hundreds and in consequence would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a very totally different story with the air motor: Due to the favourable torque characteristics of air motors, a lower-powered drive will suffice. You could select an air motor with a nominal torque of 15 Nm and nominal pace 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 underneath mild load. The power required for this air motor is subsequently only 430W. The energy 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 solely require a 3rd of the ability of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on a long time of expertise within the field of air motors. They have a extensive range of high quality, globally in style industrial drive options. Are the ADVANCED LINE motors a special resolution for meals business 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 wants of our customers. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects benefit from long-established dependable drive options for the food trade and medical expertise. We are in a position to provide these motors in a large energy range from 20 W to 1.6 kW combined with a wide selection of planetary gears from our own production with speeds of 7 to 24,000 rpm.
