摘要： A computer may display on a graphical user interface (GUI) a component library including a set of components relating to a compressed air system. The GUI may have a modeling interface for configuring a virtual model using the set of components. The computer may simulate the virtual model to determine one or more optimizations to the compressed air system. The computer may also determine the cost of implementing the compressor system optimization.

摘要： The present invention is a fluid distribution system comprising connected conduits (e.g., lines) wherein fluid flows, such as pipes within a building. The lines may be configured to: (i) include multiple lines that connect at intersections (some of the intersections will be identified as nodes); and (ii) incorporate node units associated with line pressure loss simulation assemblies (“LLSAs”). Activities of a node unit incorporating a LLSA can result in alterations in fluid pressure, such as by a loop control process to reposition balancing valves or other valves of one or more LLSAs, and/or by alteration of the speed of the system pump. These activities adjust fluid pressure to cause the system to produce a balanced and high efficiency energy transfer (e.g., heating or cooling), and do not involve or require any identification or use of any specific, fixed or absolute pressure value. They function based on an operation locus (for a node unit) and/or an operation locus range (for node unit groupings) to adjust the fluid pressure.

摘要： Embodiments disclosed herein are directed to a drainage control system including, a tubular body with a tubular body lumen extending from a distal end to a proximal end and a collapsible tube disposed within the tubular body lumen, the collapsible tube including a collapsible tube lumen extending from a distal end to a proximal end of the collapsible tube. The collapsible tube can be attached to the tubular body, such that fluid flow through the tubular body lumen flows through the collapsible tube lumen. The tubular body can include a valve that is actuatable between a first configuration wherein fluid flow is allowed through the tubular body lumen and a second configuration wherein fluid flow is prevented through the tubular body lumen. An airflow source can be coupled to the valve such that pressure from the airflow source actuates the valve.

摘要： An integrated diagnostics system utilizes online and offline diagnostics techniques to evaluate control valves found in process plant environments. The integrated diagnostics system improves on existing diagnostic systems, which typically rely exclusively on online diagnostics or offline diagnostics.

摘要： A fluid level measurement system, including an instrument line configured for installation within a fluid storage tank or vessel, the instrument line having a first end configured to be installed below a fluid level of the storage tank and a second end configured to be installed above the fluid level of the storage tank, the first end including a first pressure diaphragm plate configured to communicate with fluid within the storage tank, a pressure sensor configured to be connected to the second end of the instrument line, and a relief valve configured to open and allow high-pressure gas in the tank to escape through a ventilation port in order to depressurize the tank until tank pressure equalizes with the surrounding atmospheric pressure.

摘要： A robotic device may traverse a path in a direction of locomotion. Sensor data indicative of one or more physical features of the environment in the direction of locomotion may be received. The implementation may further involve determining that traversing the path involves traversing the one or more physical features of the environment. Based on the sensor data indicative of the one or more physical features of the environment in the direction of locomotion, a hydraulic pressure to supply to the one or more hydraulic actuators to traverse the one or more physical features of the environment may be predicted. Before traversing the one or more physical features of the environment, the hydraulic drive system may adjust pressure of supplied hydraulic fluid from the first pressure to the predicted hydraulic pressure.

摘要： A packaging machine with an atmosphere modifying station in which an atmosphere within a packaging to be produced can be modified by evacuating air and/or introducing a gas. The packaging machine has a pressure control device that may control an evacuation pressure and/or a gassing pressure. The pressure control device may comprise a first controllable 2/2-way valve and a second controllable 2/2-way valve, both which are configured to influence the evacuation pressure and/or the gassing pressure by setting a volume flow. The first and second 2/2-way valves are connected in parallel with one another and are controllable independently of one another. In one embodiment, the first and second 2/2-way valves are preferably electrically controllable. A method of modifying an atmosphere within a package using a packaging machine and pressure control device is also provided.

摘要： A plural component dispensing system includes a dispensing device, first and second fluid component sources, a system controller, and an operator interface device. The first fluid component source is connected to the dispensing device to deliver the first fluid component to the dispensing device. The second fluid component source is connected to the dispensing device to deliver the second fluid component to the dispensing device. The system controller is connected to regulate operation of the first fluid component source and the second fluid component source to produce a target ratio of the first fluid component and the second fluid component at the dispensing device. The operator interface device is remote from and operatively connected to the system controller. The operator interface device is configured to output system state information received from the system controller and to receive operator input to control an operational state of the system controller.
