摘要： A multi-stage blowdown valve is provided that uses a single control signal to simultaneously decompress the interstage and the second stage in a compressor system. The valve uses a series of sliding spools located linearly within a single bore to either prevent or allow fluid communication between two isolated passageways each having an inlet port and a discharge port. The valve, when used as a two stage blowdown valve in a multi-stage compressor system, can prevent compressor failure from occurring by ensuring that both the interstage and the second stages are decompressed, not only the interstage.

摘要： An electronic control system dynamically varies the output capacity of a compressor by controlling plural valves associated with the compressor to provide pressurized air to a distribution system at an appropriate rate. The control system operates in any of three modes for standalone operation, including continuous run, auto/dual pressure band, and target pressure modes. In the first two modes, pressure bands are dynamically calculated based on load and unload values entered by an operator. These electronic control systems can also be connected in a peer-to-peer network to coordinate control of up to 16 compressors feeding the same distribution system, so as to maintain a desired target pressure in the system. A modem connected to the system supports remote diagnostics, monitoring, and control. Specialized startup, operating, and shutdown diagnostic algorithms prevent damage to the compressor and avert unsafe operating conditions.

摘要： An electronic control system is disclosed to control and to prevent damage to a standalone or a network of oil free, two stage compressor packages. The electronic control system uses pressure and temperature sensors to detect actual shutdown conditions or predict shutdown conditions based on the operating state of the compressor package and the current temperatures or pressures of the air at strategic locations in the compressor package. It has been determined through experimentation that, if the pressure at the inlet of the stage two compressor is less than the discharge pressure of the stage two compressor by more than an allowable value, then a high temperature condition will occur in the stage two compressor and cause the compressor to seize. It has also been determined the pressure differential occurs first in this situation and that the electronic control system can predict the failure based on the pressure differential data and to shut the compressors down before the stage two compressor failure occurs. The electronic control system then records the shutdown event in an area of nonvolatile memory and displays the reason for the shutdown on a LCD display visible to the compressor operator. A plurality of electronic control systems can be connected in a peer-to-peer network to coordinate control of a plurality of compressors connected to the same air distribution system. A modem connected to the electronic control system supports remote diagnostics, monitoring, and control. Methods for controlling the operation of the compressor packages using the electronic control system are also disclosed.

摘要： Systems and methods, including modem communications software, for controlling and/or monitoring one or more machines having an control board, such as, for example, compressors, from a remote location is disclosed. The systems and methods provide for each machine being controlled and/or monitored by an operator from the remote location. The machines are controlled and/or monitored using the modem communications software, presently preferably, resident on a personal computer (PC) at the remote location. The methods and systems, including the modem communications software, provide communications between the PC and the machine(s) through transmissions over a communications link established through a modem from a remote PC to a modem connected to the control board of a machine to provide instructions to or receive information from the machine control board and for the remote diagnosis of operating problems, such as, for example, compressor system operating problems, among other features.
