  • Patent number: 11319794
    Abstract: A pumpjack monitor includes a processor and memory, a communicator for communicating with other monitors and a server, a sensor module having at least one strain gauge, and accelerometers for determining vibration and position of the monitor. Other sensors may be internal, including sensors for polished-rod rotation, and linked to the monitoring device wirelessly. Some embodiments serve as network hubs or bridges for other monitors. The server is configured to generate surface cards. A method for monitoring of pumpjacks uses the monitor to sense changes in pumpjack parameters, and communicate the changes to a server when changes exceed configurable thresholds. Some embodiments include determining location with GPS and/or relaying signals from other monitoring devices, smart power management, gas sensing, and relaying of signals from external wireless-equipped sensors such as valve position sensors, oil level sensors, and pressure sensors.

  • Patent number: 11319942
    Abstract: A compressor includes a motor body having a gas compressing motor, at least a pneumatic cylinder for compressing gas, and at least a cooling fan. The pneumatic cylinder comprises a cylinder support arranged on top of the compressing motor, a valve panel arranged on top of the cylinder support, a cylinder cover provided on top of the valve panel, and a piston connecting rod body slidably connected with the cylinder support. The heat dissipating channels, the gas channels, and the heat dissipating passages are arranged in series to jointly form a heat dissipation path, such that when the piston connecting rod body is driven by the compressing motor to conduct a gas compressing process in the cylinder support, the cooling fan is also driven to operate to drive the external gas to flow through the heat dissipation path and to flow out, so as to bring out the heat produced during the operation of the pneumatic cylinder and to achieve an effective heat dissipation.
