Results The Results for the labs are enclosed in the attached lab handouts. Conclusions/Recommendations Pneumatic circuits work particularly well for safety circuits, especially those that are remotely operated, are directly operated from two locations using a shuttle valve and are interlocked with an AND operation. It is recommended that circuits be constructed with an AND operation by constructing it with 2 valves or some type of safety component, like a push button or Omron’s OS32C Safety Laser Scanner, in parallel to ensure that two conditions must be met before the hydraulic circuit will operate. It can be advantageous to restrict the exhaust port of a valve so that the fluid, and therefore pressure, remains in the cylinder, making it available for another actuation cycle. It is also recommended that accumulators be considered for safety circuits as well. Accumulators hold pressure which can smooth fluid flow, thereby decreasing pulsation, as well as maintain a reserve of pressure to allow for more immediate actuation. Real-world applications Safety circuits are present throughout industry where machine operation can cause injury or death and can be built with pneumatically powered circuits and can include accumulators. Applications include presses, shears, CNC machines and stamping equipment. Furthermore, accumulators
are used when a system must maintain a reserve of pressure, for example, in case of system failure or for smoother or more immediate pressure release downstream. Such applications include automotive suspension systems and blowout prevention systems on oil rigs.
Report Introduction/Purpose The purpose of these labs is to expand on existing knowledge of hydraulic circuits by focusing on the basics of pneumatic circuits and accumulators. Students learned about circuits with speed control of an actuator, flow amplification for remote control of a large actuator and safety interlock circuits using the AND principle. Approach/Methodology To accomplish these purposes, the basics of safety operations, accumulation of pressure, and the differences between liquid and air being used as fluids were covered. Circuits were created following the diagrams enclosed in the lab manual using the Bosch Hydraulic Trainer and all required components, including but not limited to remote push-button valve, pilot operated valve, single-acting cylinder, accumulator, shuttle valve, and flow control valve. Data Data Lab 11 Implications of Data Lab 11 As the volume of fluid in the accumulator increases, pressure increases. This is due to the limited volume of the accumulator being filled with an increasing volume of fluid, which causes the pressure inside of it to increase.
POST EXERCISE QUESTIONS Lab 8 Questions: Exercise 1: Remote Operation and Flow Amplification 1. Why would you want remote activation of the 3/2 valve?
