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

Automated processes are commonplace follow within the food business. Production effectivity just isn’t the one motivation, hygiene also plays a key function within 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 requirements and incorporate both these goals.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to make sure that the proper drive is selected to meet the excessive necessities for hygiene within the meals trade, we normally recommend our ADVANCED LINE air vane motors. เกจวัดแรงดันแก๊สอาร์กอน are made from stainless steel and are impervious to normal cleaning agents. The smooth surface of those air motors is straightforward to clean. The drives are so nicely sealed with sturdy long-life radial shaft seals that no air can escape and equally no filth, water or different solutions can penetrate the motor. The motors are even immune to water penetration from generally used cleansing spray methods. A moist environment is not any concern for this motor. It can even be used underwater as in the case of many stirring purposes. All our ADVANCED LINE chrome steel motors are lubricated with meals grade USDA-H1 grease and can be operated oil-free. A power discount of approx. 10-20% primarily based on the technical data acknowledged within the product catalog must be taken into account when designing drives for oil-free operation.
Question: Does an air motor need to boast different options for such applications?
Answer: Yes. In many applications, condensation can type in air provide strains. It is due to this fact advisable that measures are taken to make sure that the motor isn’t positioned at the lowest point in the system and that it could 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 components within the motor’s interior which are produced from stainless-steel. This is as a outcome of there’s a restrict to the use of stainless-steel for heavy obligation, high-speed internal components. This so-called CWL coating provides insensitivity to corrosion.
Question: Do you could have any examples of the place your motors can be utilized within the meals 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 countless. I’ll describe a few applications in more element, corresponding to the usage of 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 on the speed of seven-hundred rpm.
We even have the perfect drive for high-torque requirements in industrial agitators: Our ADVANCED LINE high-torque motors generate immense power in the smallest of spaces. The 900W high-torque motor with a nominal speed of 22 rpm overcomes a beginning torque of 585 Nm and has a maximum diameter of sixty three mm.
Another software can 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 licensed for use in potentially 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 เกจวัดแรงดันน้ําไทวัสดุ , two air motors are used to drive belts which pierce a wood skewer through pieces of meat, onion and pepper. Pressure on 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 electrical motor in such applications?
Answer: There are many arguments in favour of using an air motor: One of the main benefits 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 size. This is especially vital when using a handheld device however of course also for robotic techniques the place the drive strikes with the robotic arm.
Heat also leaves the air motor cold. In critical settings, compressed air is an unproblematic supply of power – it doesn’t evaluate to the hazards of electricity. The energy output from the air motor over extensive torque ranges is sort of fixed. Air motors can due to this fact be optimally operated in a large subject of fluctuating loads. There isn’t any problem with load being applied on the air motor till standstill, no damages are incurred. This means it’s less apt to stalling. After discount of the load, it’ll run again instantly and any number of successive instances. Air motor energy could be adapted simply by adjusting the working strain. The speed is lowered smoothly by throttling the air volume. Throttling supply air is beneficial when torque also needs to be significantly decreased. Exhaust air throttling must be chosen to reduce pace without any critical influence on the torque.
Question: Air motors are often seen to be less environment friendly in comparison with electrical 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 always is determined by the circumstances of the applying. Let me use this instance to clarify: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is applied at decreased speed over a protracted time period to safe the packaging tape. Electric motors cannot be loaded over a protracted time frame with out working the risk of overheating. Therefore, for this packaging machine, an electrical motor would wish to resist excessive hundreds and in consequence would need to be 1170W (25 Nm x 450 rpm divided by 9550). It is a totally 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 speed 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 under light load. The power required for this air motor is due to this fact solely 430W. The vitality stability of an air motor is seen in a completely totally different light when you consider that the air motor wanted for this packaging machine would solely require a third of the ability of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can mirror on many years of experience in the field of air motors. They have a broad range of top quality, globally popular industrial drive solutions. Are the ADVANCED LINE motors a particular resolution for food business applications?
Answer: It is true that our engineers have continued to optimise our air motors over the decades and our commonplace program has been adjusted to satisfy the needs of our customers.
