Motivation: This project is motivated by the need of an automated safety system for the steam generating unit of a company. This system is required in the company following an accident that occurred in the company due to a miss communication between the maintenance and operation teams that resulted in collapse of a tank. A safety relief valve used to maintain pressure inside the tank was removed during maintenance and the operation team resumed operation before the valve was restored leading to a vacuum in the tank that lead to the collapse of the tank. By having a system to automatically monitor pressure inside the tank and alert the operation team in case of pressure imbalance, such accidents can be minimized considerably. In all industries, equipment such as motors, pumps, belts, gear trains and couplers are subject to wear and tear during use that would eventually result in unscheduled shutdown. Cavitation one of the areas of interest of this research results in deterioration of performance of pumps that may lead to failure of the pump. These unscheduled shutdowns lead to idle personnel and equipment that are usually expensive to maintain. By early detection of cavitation, these maintenance costs can be avoided. The motivation for this project therefore is to design a cost effective, efficient system that automatically diagnoses pumps for degradation and cavitation to be able to predict pump failure thus decrease the large costs associated with idle equipment and personnel due to unscheduled shut downs. Objectives: The main objective of this project is to develop a system that would improve safety in a steam production unit by use of sensors interfaced to a controller which controls actuators such as valves and an alarm when vacuum start to reach critical level inside the tank. Another major objective is to design a system for automatically monitoring cavitation in a water pump and reduce the speed or stop it until the problem is resolved. Note: All measurements can be estimated for this project e.g. tank size and pump since we don't have real measurements.

Hi, I have a Lab view 2017 program and I need to make it executable (.exe). I need someone that take what I have done with the demo version (the program is finished and no extra programing is requiered) and make it an executable file so I can send to my cliente. The software has to be legal and has all the requiered original license from labview. Thanks
This project (hopefully the first of many), will be based on making an alternative designed 'check weigher' for my very small factory. I need to take a minimum of 50 bottles per day off of my conveyor belt, weight them on a load cell, then have that weight automatically recorded and alert me if it is out of tolerance. The bottle must then be put back on to the conveyor belt. For the initial prototype I would need a simple Bill Of Materials to be created using [url removed, login to view], and assistance with the PLC programme. I will be using a Siemens Logo 8 most likely, but Arduino or other alternative systems would be OK too. We are looking to strike the best compromise between price and functionality. I would ask you to look at my initial ideas, make them better where possible, and then help me to design the hardware set up that is needed to operate it. If you think that there is a better way of doing what I'm aiming for then we can start from scratch! It is quite simple stuff (in my opinion). My initial (untested) thoughts were that I could set up a couple of pneumatic pistons to act as gates on the conveyor, (running 1,000 to 2,000 bottles per hour) then push a bottle on to a load cell adjacent to the conveyor (while releasing the gates to allow the other bottles down the line), have the load cell record the weight and alert me if it is outside of tolerances, then push it back on to the conveyor. As we would only be needing to weigh 50 bottles per day the requirements of the hardware should be quite low. Some parts will undoubtedly have to be hand fabricated here in-house. Alternative ideas are most welcome.

Imase Seguridad S.L., instaladora e ingeniería de sistemas de seguridad se encuentra en proceso de instalación de un sistema centralizado de Seguridad que abarca la integración de equipos con protocolo OPC entre el software de integración VIS de Bosch y los PLC's Logo de Siemens. Para ello, se pretende el desarrollo de las comunicaciones, desarrollo de necesidades, desarrollo de comandos entre ambos sistemas y formación y explicación de los trabajos realizados ya que el desarrollo pasará a ser propiedad de Imase Seguridad en la entrega del trabajo. El proyecto y la definición de los trabajos a realizar está en fase de desarrollo siendo esta una aproximación al proyecto final, por lo que el proyecto está abierto a modificaciones y preguntas.
I am machine that came with Weintek HMI and Delta PLC. The seller also provide backup of the programs code. I like someone familiar with the programming to help me checkout the backup codes to see if is like the seller has claimed before I accept the machine.
The aim is to develop a conveyor system that is able to transport ampoules and vial and to perform certain actions. The system needs - an infeed for glass ampoules and vials - (at least) two conveyors that allow feeded containers to circular back an the end of the one conveyor (appr. 5 m long) - a sensor that creates a gap of appr. 1cm after each 5 containers (to be defined in a PLC/HMI) In addition, - ampoules/vials must not fall over and appropriate measures have to considered to handle containers that felt over - different container diameters must be able to be processed (between 10-30mm diameter) - project owner must take full responsibility for a working system - on each side of the returning conveyor systems, 5 person will sit to pick up these ampoules - the speed must be 250 containers per minute
make programme for a automatic paper cutting machine. cut from a roll into sheets. 1 stepper motor for the feeding rotor 1 stepper motor for the cutting mechanism on a linear rail 2 mechanical end switches on the linear rail (when stepper motor moves wrong or loose steps -> also used as reference point) 1 sensor to know when the roll is empty 1 emergency button 1 display to: - set the milimeters for the paper lenght - start and stop the machine - move the stepper motor for the feeding rotor in both directions by press a button in both directions - move the motor on the linear rail by pressing a button in both directions set the quantity of needed paper sheets short description: - user start machine - user get information on display that machine will move to reference point and need to press "OK" machine move to reference point on the linear rail (on left or right side of the rail) and move few milimeters away from the mechanical switches to the start point (mechanical switches should be really just be used on machine fault) - user set the needed lenght of paper in display (which we need to calibrate one time and set in programme -> how many steps of the stepper are how many milimeter paper) - user set needed quantity of paper in computer - user put the roll of paper on the machine and press the button for manually rotate the feeding rotor to put the paper to the cutting mechanism - user press a button to move the slide of the rail from start point to the other end point of the - slide (to cut the paper) - when all is ok, user press "AUTOMATIC" button and machine cut automatic the set quantity of sheets and stop. more details or other plc- system (which need to control stepper motors-> 100-400khz- outputs) are welcome.
I want a team / somebody who can develop a digital control pulse mig welding machine for me. The output current should = 400 Amps There should be CC/CV feature in that. The Wire feeder motor should be rotary encoder based. The smooth welding of Aluminum, SS & MS should be possible with that.
