Why do Teenagers want to be Entrepreneurs?

 “Just making money is hello from the past”: Why kids need to learn business in school Teenagers very often face a common problem after university. They don’t know what they want to be or do next. Someone goes into freelancing, and becomes a paper writer or manager, for example. And someone goes to work not by specialty only for the sake of a good salary. Teenager Entrepreneurs How to develop a children’s business and why raise teenager to be an entrepreneur, even if he will work for hire or in a non-specialty in the future. “The global problem is that children learn for grades.” In Northern Europe (e.g., Norway) entrepreneurship begins at school. This is how competencies are developed that can be useful to everyone in life. It all starts with the economy of one’s own family: by managing their own money, the child becomes accustomed to managing finances in general. If this skill is laid down in childhood, a special life paradigm is formed. In the future, he will no longer think tha...

HT Motor Direction of Rotation (DOR) Changed

 Electrical engineering root cause analysis (RCA) related to considered not possible HT motors’ Direction of Rotation (DOR) changed. Note: This root cause analysis (RCA) is from real-time scenarios that happened in industries during the tenure of two or three decades ago. These articles will help you to improve your troubleshooting skills and knowledge. HT Motor Direction of Rotation (DOR) Why Direction of Rotation (DOR) arrows? Large motors’ come with backward-curved fans (below figure). They deliver max air-flows at marked Direction of Rotation (DOR) and very little in the opposite DOR. Consequently, the winding temperature could go a lot higher than permitted. It could shorten winding lives even lead to burnouts. This is especially serious, as most motors have no winding temperature indicators (at that time). Hence, DOR marks. However, one can change DOR to suit the driven machine thus: swap the left and right internal axial fans (IAF above-figure) Substitute the existing Extern...

Technologies for Oxygen Gas Measurement

 We have many technologies available for oxygen gas measurement in industrial applications. Some of them are discussed in this article. A colorless, odorless gas, oxygen makes up approximately 21% of the Earth’s atmosphere. It is essential to human life, and so is vital to many medical gas applications, as well as playing an essential part in many industrial process reactions. Within the industry, it has a wide range of uses, including the production of metals and plastics. Many manufacturing processes rely on the use of oxide compounds, so an extensive variety of applications depend upon oxygen measurements for process control, safety, and efficiency. Also, while oxygen is not harmful to the environment, it may be necessary to monitor oxygen emissions as part of a continuous emissions monitoring system. Table of contents Zirconia Oxygen Measurement Coulometric Oxygen Measurement Paramagnetic Oxygen Measurement Tunable Diode Laser Oxygen Measurement Conclusion There are a number of...

Sox Nox Analyzer

 CEMS (Continuous Emissions Monitoring System) is required in power plants, cement plants, fertilizers, steel plants, etc., to monitor air pollution. CEMS measuring methods can be classified into two categories. The data of Sox & Nox can be continuously sent to the pollution control board through a wireless network for monitoring purposes and optionally from the pollution board can do zero and span gas calibration through remote mode. Extraction type In-situ type In this article, we discuss extraction type. In analyzer panel, SS tubing material is used to avoid corrosion because of gas. Sox Nox Analyzer Sox Nox analyzer unit consists of suction pump, electric heater, No2 converter, rotameter, calibration gas cylinders, auto drain valve, SMPS, moisture detector, PLC unit, HMI. Suction Pump A suction pump is used to grab the sample from the chimney and sends it to the Sox Nox analyzer unit. It is provided with a 230 VAC power supply. Electric Heater In order to prevent the sample...

Basic Pumping System Application Used in Industrial Automation

 In this post, we will see the basic pumping system application that is used in industrial automation. A pumping system is one of the widely used applications used in industrial automation. Earlier, manual control was used where the operator had to go and start or stop the pumps according to pressure requirements from the user. Pumping System Basically, a pumping system in simpler terms can be viewed as the one used in your building. The society keeper (or watchman, or ourselves in our homes) controls the pump operation according to the flushing and domestic water requirements in the building. Now, due to the use of PLC in the pumping systems, the manual intervention is reduced to a great extent, and also, the pressure control is achieved more accurately due to the use of automation. Refer to the above image. A typical pumping system used for domestic, commercial, and industrial purposes looks like this. It consists of multiple pumps (depending upon pressure-demand design), its cor...

PLC Program for Mixing Tank

 Create a ladder diagram for controlling a batch mixing process. Implement a PLC program for mixing tank or Mixing Process using PLC Ladder Logic. PLC Program for Mixing Tank Fig : Mixing tank A tank is used to mix two liquids. The required control circuit operates as follows: A. When the START button is pressed, solenoids A and B energize. This permits the two liquids to begin filling the tank. B. When the tank is filled, the float switch trips. This de-energizes solenoids A and B and starts the motor used to mix the liquids together. C. The motor is permitted to run for 1 minute. After 1 minute has elapsed, the motor turns off and solenoid C energizes to drain the tank. D. When the tank is empty, the float switch de- energizes solenoid C. E. A STOP button can be used to stop the process at any point. F. If the motor becomes overloaded, the action of the entire circuit will stop. G. Once the circuit has been energized, it will continue to operate until it is manually stopped. Solution...

PLC Output Types

 PLC outputs are of two general types: (1) relay (2) solid state Relay outputs are mechanical contacts and solid state outputs may take the form of transistor or TTL logic (DC) and triac (AC). Relay outputs are usually used to control up to 2 amps or when a very low resistance is required. Transistor outputs are open collector common emitter or emitter follower. This type of output can control lamps and low power DC circuitry such as small DC relays. TTL logic outputs are available to drive logic circuitry. Triac outputs are used to control low power AC loads such as lighting, motor starters and contactors. As with input units, output units are available with a common terminal and isolated from each other. The type of output unit selected will depend upon the outputs being controlled and the power available for controlling those devices. Typically, power for driving output devices must be separately provided since there can be a wide range of requirements depending upon the device....
