Automated เกจวัดแรงดันไฮดรอลิค are normal follow within the food industry. Production effectivity is not the one motivation, hygiene also performs a key function in the food business. We met with DEPRAG SCHULZ GMBH u. CO. Product Manager Dagmar Dübbelde to debate how to design a drive to meet these requirements and incorporate both these objectives.
Question: How are high standards of hygiene met by DEPRAG?
Answer: In order to make certain that the right drive is chosen to satisfy the excessive necessities for hygiene in the food business, we often advocate our ADVANCED LINE air vane motors. All their external parts are produced from stainless steel and are impervious to regular cleansing agents. The clean floor of these air motors is simple to clean. 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 proof against water penetration from generally used cleansing spray techniques. A moist surroundings is not any concern for this motor. It may even be used underwater as in the case of many stirring purposes. All our ADVANCED LINE stainless-steel motors are lubricated with food grade USDA-H1 grease and may be operated oil-free. A energy discount of approx. 10-20% based mostly on the technical information stated in the product catalog must 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 form in air supply lines. It is subsequently advisable that measures are taken to ensure that the motor isn’t positioned on the lowest level within the system and that it can be flushed out with water. Many users take precautionary measures, not only relating to the layout of the motor in their system, but also concerning the use of water separators or dryers in front of the drive. If all this is not potential, then we advocate a particular coating for those parts throughout the motor’s inside which are made from stainless steel. This is because there’s a limit to using stainless steel for heavy responsibility, high-speed inner parts. This so-called CWL coating offers insensitivity to corrosion.
Question: Do you have any examples of the place your motors can be utilized in the meals industry?
Answer: Stirring dough, moving and chopping sheets of dough, rotating pork stomach skewers, mixing sausage meat or unwinding sausage skins, the meals business functions are infinite. I’ll describe a number of functions in additional detail, corresponding to the use 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 pace of 700 rpm.
We even have the perfect drive for high-torque necessities in industrial agitators: Our ADVANCED LINE high-torque motors generate immense energy in the smallest of spaces. The 900W high-torque motor with a nominal velocity of 22 rpm overcomes a starting torque of 585 Nm and has a maximum diameter of 63 mm.
Another utility may be found in grinding mills and conveying methods for grain processing. In this case, the focus is on mud technology and explosion prevention. All our ADVANCED LINE motors are ATEX licensed to be used in probably 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 the skewer unit, two air motors are used to drive belts which pierce a wooden skewer through pieces of meat, onion and pepper. Pressure on 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 using an air motor: One of the principle benefits is its high energy density. Depending on the design, an air motor has only a fifth of the mass of an electric motor, or a third of its measurement. This is especially vital when using a handheld gadget but after all also for robotic methods the place the drive strikes with the robot arm.
Heat additionally leaves the air motor chilly. In important settings, compressed air is an unproblematic source of power – it doesn’t evaluate to the risks of electrical energy. The energy output from the air motor over broad torque ranges is nearly constant. Air motors can subsequently be optimally operated in a large subject of fluctuating loads. There is not any 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 once more instantly and any number of successive instances. Air motor energy can be adapted simply by adjusting the operating pressure. The speed is reduced easily by throttling the air quantity. Throttling supply air is beneficial when torque must also be significantly reduced. Exhaust air throttling must be chosen to reduce back pace with none serious influence on the torque.
Question: Air motors are sometimes seen to be much less environment friendly in comparability with electrical motors. Can you comment on 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 dependent upon the conditions of the applying. Let me use this instance to explain: A motor which reaches speeds of 450 rpm is needed for a packaging machine. 25 Nm torque is utilized at lowered velocity over an extended period of time to secure the packaging tape. Electric motors can’t be loaded over an extended time period with out operating the chance of overheating. Therefore, for this packaging machine, an electrical motor would wish to face up to high hundreds and in consequence would must be 1170W (25 Nm x 450 rpm divided by 9550). It is a completely totally different story with the air motor: Due to the favourable torque characteristics of air motors, a lower-powered drive will suffice. You may choose an air motor with a nominal torque of 15 Nm and nominal pace of 275 rpm. Since the working torque is under that of the nominal torque, the air motor runs near idle pace at 450 rpm under light load. The energy required for this air motor is due to this fact only 430W. The energy stability of an air motor is seen in a totally completely different light when you consider that the air motor needed 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 expertise in the field of air motors. They have a variety of prime quality, globally in style industrial drive solutions. Are the ADVANCED LINE motors a particular resolution for food trade applications?
Answer: It is true that our engineers have continued to optimise our air motors over the a long time and our commonplace program has been adjusted to meet the needs of our prospects. The ADVANCED LINE motors belong to our DEPRAG catalog program. Our clients profit from long-established reliable drive solutions for the food business and medical expertise.
