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

Automated processes are standard practice within the meals industry. Production efficiency just isn’t the only motivation, hygiene also plays a key position in the food business. 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 targets.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to make sure that the proper drive is selected to fulfill the high necessities for hygiene within the meals business, we often advocate our ADVANCED LINE air vane motors. All their exterior components are created from stainless-steel and are impervious to regular cleaning brokers. The easy floor of these air motors is easy to scrub. The drives are so properly sealed with sturdy long-life radial shaft seals that no air can escape and equally no filth, water or other solutions can penetrate the motor. The motors are even proof against water penetration from commonly used cleansing spray systems. A moist surroundings isn’t any concern for this motor. It may even be used underwater as in the case of many stirring functions. All our ADVANCED LINE stainless steel motors are lubricated with food grade USDA-H1 grease and can be operated oil-free. A power discount of approx. 10-20% primarily based on the technical information stated in the product catalog should 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 traces. It is therefore advisable that measures are taken to ensure that the motor is not positioned on the lowest point within the system and that it can be flushed out with water. Many users take precautionary measures, not solely referring to the layout of the motor in their system, but additionally concerning the use of water separators or dryers in front of the drive. If all this is not possible, then we recommend a special coating for these components throughout the motor’s inside that are created from stainless steel. This is because there is a restrict to the use of chrome steel for heavy obligation, high-speed inner elements. This so-called CWL coating supplies insensitivity to corrosion.
Question: Do you have any examples of where your motors can be utilized within the meals industry?
Answer: Stirring dough, shifting and slicing sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the food business functions are countless. I’ll describe a couple of functions in additional element, similar to the utilization 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 pace of seven-hundred rpm.
We also have the perfect drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy 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 maximum diameter of 63 mm.
Another utility can be found in grinding mills and conveying systems for grain processing. In this case, the main focus is on dust technology 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 instance 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 picket skewer through pieces 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 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 advantages is its high energy 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 vital when utilizing a handheld gadget but after all additionally for robotic systems the place the drive strikes with the robot arm.
Heat also leaves the air motor chilly. In crucial settings, compressed air is an unproblematic supply of energy – it does not evaluate to the risks of electrical energy. The power output from the air motor over extensive torque ranges is kind of constant. Air motors can due to this fact be optimally operated in a wide area of fluctuating hundreds. There is not any drawback with load being applied on the air motor until standstill, no damages are incurred. This means it is less apt to stalling. After reduction of the load, it will run again immediately and any number of successive occasions. Air motor energy may be tailored simply by adjusting the working pressure. The pace is lowered easily by throttling the air quantity. Throttling provide air is beneficial when torque also needs to be significantly lowered. Exhaust air throttling must be chosen to reduce velocity with none severe affect on the torque.
Question: Air motors are often seen to be less efficient compared to electrical motors. Can เพรสเชอร์เกจไฮดรอลิค comment on this statement?
Answer: Air motors and electric motors can’t be compared on a one-to-one basis. The effectivity of a drive always is decided by the circumstances of the appliance. Let me use this instance to elucidate: A motor which reaches speeds of 450 rpm is required for a packaging machine. 25 Nm torque is utilized at reduced pace over an extended time frame to safe the packaging tape. Electric motors cannot be loaded over a protracted time period without working the danger of overheating. Therefore, for this packaging machine, an electric motor would wish to face up to excessive masses and in consequence 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 could choose 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 near idle velocity at 450 rpm under mild load. The energy required for this air motor is due to this fact solely 430W. The energy balance of an air motor is seen in a totally completely different gentle when you consider that the air motor needed for this packaging machine would only require a 3rd of the power of an electrical motor.
Question: DEPRAG SCHULZ GMBH u. CO. can replicate on a long time of expertise in the field of air motors. They have a wide range of high quality, globally in style industrial drive options. Are the ADVANCED LINE motors a particular solution for food business applications?
Answer: It is true that our engineers have continued to optimise our air motors over the many years and our normal program has been adjusted to fulfill the wants of our customers. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our prospects benefit from long-established reliable drive options for the food business and medical know-how.
