    Abstract: In an air compressor which can cope with an item to be replaced which is not a manufacturer's recommended item so as to enhance the safety, there is provided, as an example, an air compressor comprising a compressor body for compressing air, an item to be replaced (in detail, for example, a suction belt, a suction filter, a separator element and an oil filter) used during the operation of the compressor body, comprising a control device for computing a service time of the item to be replaced, from an operation time of the compressor body, discriminating whether the item to be replaced is a manufacturer's recommended item or not, determining whether or not the service time of the item to be replaced, which is discriminated as a manufacturer's recommended item, exceeds a preset first reference time, but determining whether the service time of the item to be replaced, which is discriminated as the one which is not the manufacturer's recommended item, exceeds a second reference time which has been preset so as to be shorter than the first reference time, and issuing an alarm if the reference time is exceeded.

    Abstract: An adhesive dispensing system includes a pump and at least one sensor positioned to sense movements of a component of the pump and produce signals based on the sensed movements. The dispensing system also includes a controller communicating with the at least one sensor to collect information regarding operational cycles of the pump based on the signals. As a result, one or more diagnostic processes are enabled at the controller during operation of the adhesive dispensing system. These diagnostic processes may include a leak rate test for the dispensing system, an overspeed detection test for the pump, and expected life cycle monitoring of the pump or other components.

    Abstract: A liquid pump control system for dry run avoidance and re-prime detection. Pump dry run conditions can be detected with improved sensitivity by measuring pump cycle speed. Pump cycle speed is determined from sensors including pressure sensors, diaphragm end of stroke indicators, check valve movement sensors, and other techniques. A controller closes a valve to reduce pump cycle speed by reducing drive air pressure or by deadheading the pump liquid outlet. When the pump re-primes, the valve is opened, pump cycle speed increases, and pumping volume flow rate increases until a dry run condition is again encountered. Time delays can be introduced to delay shutting down or restarting the pump, for example to give a liquid source tank time to refill. The improved control sensitivity provides improved shut-down and re-start performance, reducing wear on the pump and reducing wasted drive air and energy consumption.

    Abstract: A simplified system and method for remotely monitoring and optionally further controlling pumpjack operating parameters of a pumpjack located at a distant site but within wireless cell phone station reception. Sensors situated on a pumpjack monitor and create analog output of operational conditions of the pumpjack. Digitizing means digitize the analog output of the sensors to digital data, and modem means transmit the digital data via a wireless cellular network to a network server. A user's computer communicates with the network server via the internet, and accesses the digital data to obtain information regarding the operational conditions of the pumpjack.
