Abstract: 本发明公开了一种双级导向无油空压机活塞，包括活塞体，活塞体外侧套接有密封环，还固定有两个相同的导向环，采用高温膨胀法将导向环分别固定在活塞体的两端，密封环与其中一个导向环自上而下分别套接和固定在活塞体的上端，活塞体上还设有紧固销。本发明采用两个导向环，对活塞上下分级导向，使整个活塞具有接触面积小、导向准确，不偏离的优点。另外，本发明采用的导向环具有导向和密封双重功能，与耐磨、耐高温的密封环配合使用，增加导向辅助密封作用，使压缩气缸具有两级密封作用，从而提高了压缩机的工作效率。

Abstract: A method of monitoring degradation of seals of a packing case includes receiving signals from a first temperature sensor installed in a first location in a housing of the packing case; receiving signals from a second temperature sensor installed in a second location in the housing of the packing case; computing, from the signals, a temperature differential between the first temperature sensor and the second temperature sensor at two or more times; and determining, at least in part from the temperature differential at the two or more times, a degradation indicator for at least one of the seals of the packing case.

Abstract: A stationary arranged sensor (4) is provided in the region of one of the dead centers of the piston movement to monitor the position of the path of motion of a piston (1) relative to a cylinder (2) whereby the sensor (4) measures the lateral distance (a) to an indicator unit (6) arranged on the piston (1). The sensor (4) is arranged in a recessed position relative to the inner surface of the cylinder (2) and is sealed toward the cylinder chamber (9) by means of a cover (8), and the indicator unit (6) on the piston (1) is designed as an anomaly (10) that is non-sensitive to contaminating deposits in the area of the face (11) of the piston (1).

Abstract: A method and apparatus for analyzing the operating condition of a machine, such as a reciprocating compressor (10), is provided. The method comprises testing for fluid flow across the closed suction and discharge valves (30-33), as well as leakage across the piston (16), when the machine is in a non-operating condition. The test apparatus may be removable attached externally to the machine by connection to the Kiene head end indicator cock (22) and the crank end indicator cock (24) or the apparatus may be built in internally of the machine.

Abstract: A method for determining a current wear (w) of a hydrostatic pump, particularly of a radial piston pump, with a variable-speed drive, where the pump is connected to a fluid passage, in which a fluid is pumped by the pump to create a current actual volume flow in the fluid passage. A current actual volume flow (Qact) is determined, by measuring the volume flow in the fluid passage at a predetermined drive-vector, a computed volume flow (Qcomp) is determined, by a first computational method, at the predetermined drive-vector, and the current wear (w) of the pump is determined, by a second computational method, which relates the current actual volume flow (Qact) to the computed volume flow (Qcomp).
