摘要： A vehicle wash component at a vehicle wash location includes a processor for controlling an operational status of the vehicle wash component, an actuator communicatively coupled to the processor and configured to operate the vehicle wash component, and a power source electrically coupled to the processor and the actuator. The processor receives a signal from a car wash controller located at the vehicle wash location, the signal for commanding control of the vehicle wash component, and upon receipt of the signal, the processor interprets the signal, generates a separate signal, and transmits the generated signal to the actuator. The actuator receives the signal from the processor for controlling the operational status of the vehicle wash component based thereon. The power source provides power to the actuator for operating the vehicle wash component based on the operational status of the vehicle wash component.

摘要： A vacuum exhaust system is provided which can reduce a size of a pump or a valve, and can thin the pipe diameter, and can perform highly efficient exhaust making the best use of exhaust characteristics of the pump from high vacuum to the large flow region. The process gas used in a vacuum chamber passes through a regulating valve, and reaches a first branch pipe. The passage on the side indicated with A in the drawing of the first branch pipe is connected with an inlet port of a second pump. On the other hand, the passage indicated with B in the drawing of the first branch pipe is provided with a bypass valve. Then, the downstream of an outlet port of the second pump and the downstream of the bypass valve are connected with a first pump via a second branch pipe. In the low and medium vacuum regions (at the time of large flow rate exhaust), the bypass valve is opened. At this time, the gas is exhausted through both the passage A including the second pump therethrough and a passage B. Then, when exhaust under medium and high vacuum conditions lower than that is performed, the bypass valve is closed, thereby performing exhaust through the passage A. As a result of this, the pipe of the passage B can be thinned.

摘要： A technique for remote pairing of pumps and manifold valves at an oilfield. The technique takes advantage of a control unit having remote capability of opening and closing manifold valves. The control unit may also be in simultaneous communication with an individual sensor for each pump. Thus, unique protocols of valve opening and closing at the manifold in conjunction with monitoring of fluid-based detections by the unit may be used to establish pairing between specific pumps and manifold valves. Similarly, the system may also be inspected for leaks at particular locations through unique valve opening and closing sequences in conjunction with fluid monitoring.

摘要： A method for controlling a managed pressure drilling system including a drillstring located in a borehole, a pump that delivers drilling fluid, and a choke that controls the flow of the drilling fluid from an annulus formed between the drillstring and the wall of the borehole. During drilling, the drilling fluid flows downwardly through the drillstring from the pump and through a drill bit, and returns through the annulus to the choke. The method includes determining a correction ΔVcorr in the volume of the fluid in the annulus to achieve a target pressure in the fluid; calculating a choke flow rate correction term Δqcorr by dividing ΔVcorr by a factor related to the acoustic travel time ta of a pressure wave in the fluid travelling the length of the annulus; and determining a flow demand from the choke on the basis of the flow rate correction term Δqcorr.

摘要： A pumping energy savings estimator is provided which, based on valve opening data collected for a control valve of a pump-valve system operating in an industrial process, determines an actual maximum (Δporg, ˜50% open) of valve operating region of the control valve of the pump-valve system. User can select a new maximum (Δpnew, ˜70% open) of valve operating region for the control valve. Then the estimator, based on the determined actual maximum of valve operating region and the selected new maximum of valve operating region, energy saving potential (Δpsave) in the pump-valve system. The potential energy savings may be put into practice by replacing the original pump with a new smaller pump, or more preferably, replacing or processing the impeller of the original pump, such that the control valve will operate with the selected new optimal maximum opening of valve operating region.

摘要： A fluid dispensing system includes a pump, a valve, and a dispenser disposed downstream of the valve and connected to the valve with a hose. To provide a steady flow rate at the dispenser, the pump charges the fluid to or above the pressure required to achieve a desired flow rate. The valve cycles between open and closed at a fixed frequency. The valve-open time is varied within that frequency to maintain the desired flow rate.

摘要： The present invention provides a water-based coating and/or coating system that can be used to form sag resistant wet layers or coatings on a wide range of substrates. The coating system is particularly effective for protecting metal-containing substrates, such as intermodal cargo containers, against corrosion. As an overview, the present invention provides water-based compositions suitable to form primer coats on substrates. Desirably, the primer incorporates a high level of one or more CAS agents for excellent sag resistance while drying in a broad range of relative humidity environments. Alternatively, modifications can be made to control temperature and humidity during spray application and drying as a way to increase sag resistance of the coating.

摘要： Apparatus, systems, and methods related to a constant-flow control valve and BTU meter assembly that has a pressure independent, constant-flow control valve assembly connectable to the fluid-based heating or cooling system. A valve stem is connected to a valve member and is rotatable as a unit relative to a valve body to change the position of valve member to change a fluid flow rate through the valve. The valve member's position relative to the fluid path is directly related to the fluid flow rate. Pressure sensors measure the pressure of fluid entering and exiting the valve body. A BTU meter assembly is connected to the valve stem, which is rotatable relative to the BTU meter assembly. A position sensor of the BTU meter assembly detects a rotational position of the valve stem relative to the BTU body. A controller of the BTU meter assembly is coupleable to the position sensor, the pressure sensors, and the temperature sensors, and the controller determines the fluid flow rate based upon the pressure drop across the valve assembly and the rotational position of the valve stem. The controller also determines energy usage of the heating or cooling device based upon the flow rate and the temperature change across the heating or cooling device.
