Automated processes are normal apply in the meals trade. pressure gauge 0 10 bar ราคา is not the one motivation, hygiene additionally performs a key position within the meals trade. 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 each these goals.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to guarantee that the right drive is chosen to meet the excessive requirements for hygiene in the meals industry, we often recommend our ADVANCED LINE air vane motors. All their external components are made from stainless steel and are impervious to normal cleansing agents. The smooth floor of those air motors is straightforward to scrub. The drives are so properly sealed with durable long-life radial shaft seals that no air can escape and equally no dust, water or different solutions can penetrate the motor. The motors are even immune to water penetration from generally used cleaning spray systems. A wet environment is not any 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 knowledge acknowledged within the product catalog ought to be taken under consideration when designing drives for oil-free operation.
Question: Does an air motor have to boast different options for such applications?
Answer: Yes. In many functions, condensation can type in air supply strains. It is subsequently advisable that measures are taken to ensure that the motor isn’t located on the lowest point within the system and that it can be flushed out with water. Many customers take precautionary measures, not only referring to the structure of the motor in their system, but additionally regarding the use of water separators or dryers in entrance of the drive. If all this is not possible, then we suggest a special coating for those parts within the motor’s inside that are created from chrome steel. This is as a outcome of there’s a restrict to using stainless-steel for heavy duty, high-speed inner parts. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you’ve any examples of where your motors can be utilized in the food industry?
Answer: Stirring dough, transferring and slicing sheets of dough, rotating pork belly skewers, mixing sausage meat or unwinding sausage skins, the meals industry applications are infinite. I’ll describe a few 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 even have the best drive for high-torque necessities 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 pace of 22 rpm overcomes a starting torque of 585 Nm and has a most diameter of 63 mm.
Another utility can be found in grinding mills and conveying methods for grain processing. In this case, the major target is on mud era and explosion prevention. All our ADVANCED LINE motors are ATEX certified to be used in doubtlessly 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 wood 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 utility.
Question: What advantages 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 primary advantages is its excessive energy density. Depending on the design, an air motor has solely a fifth of the mass of an electric motor, or a 3rd of its size. This is particularly vital when using a handheld device but after all additionally for robotic systems the place the drive moves with the robot arm.
Heat additionally leaves the air motor chilly. In critical settings, compressed air is an unproblematic supply of power – it doesn’t evaluate to the hazards of electricity. The power output from the air motor over broad torque ranges is almost constant. Air motors can subsequently be optimally operated in a large field of fluctuating loads. 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 discount of the load, it will run again instantly and any variety of successive instances. Air motor power could be adapted just by adjusting the working stress. The pace is decreased easily by throttling the air volume. Throttling provide air is recommended when torque also wants to be considerably lowered. Exhaust air throttling should be chosen to reduce pace without any serious affect on the torque.
Question: Air motors are often seen to be much less efficient compared to electric motors. Can you touch upon this statement?
Answer: Air motors and electrical motors can’t be in contrast on a one-to-one foundation. The effectivity of a drive always depends on the conditions of the application. Let me use this example to clarify: 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 can’t be loaded over a protracted time frame without running the chance of overheating. Therefore, for this packaging machine, an electric motor would want to face up to excessive masses and as a result would have to be 1170W (25 Nm x 450 rpm divided by 9550). It is a very completely different story with the air motor: Due to the favourable torque characteristics 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 beneath that of the nominal torque, the air motor runs near idle speed at 450 rpm beneath mild load. The power required for this air motor is therefore only 430W. The energy balance of an air motor is seen in a completely different gentle when you suppose about that the air motor needed for this packaging machine would only require a third of the power of an electric motor.
Question: DEPRAG SCHULZ GMBH u. CO. can reflect on many years of expertise in the area of air motors. They have a broad range of high of the range, globally well-liked industrial drive options. Are the ADVANCED LINE motors a special answer for meals industry applications?
