摘要： A lubrication system includes a progressive distributor that is configured to dispense lubricant to a consumer. The lubrication system also includes a control device and at least one sensor that is configured to determine at least one lubricant pressure inside the lubrication system. The control device is configured to receive measured values from the at least one sensor and to recognize a lubrication cycle based on the measured values and also to determine an average pressure of the lubrication cycle, to perform a comparison of the average pressure and at least one normal pressure of the lubrication system, and to determine a state of the lubrication system based on a result of the comparison.

摘要： Provided is an oil feed type air compressor which can increase the determination accuracy regarding a deterioration state of oil. An oil feed type air compressor 1 includes a compressor main body 3, a separator 6 that separates oil from compressed air discharged from the compressor main body 3, and an oil feeding system 8 that feeds the oil separated by the separator 6 into a compression chamber of the compressor main body 3. The oil feeding system 8 includes a temperature control valve 20 that adjusts a diversion ratio for an oil cooler 18 and a diversion ratio for a bypass pipe 19 according to a temperature of the oil. The oil feed type air compressor 1 includes pressure sensors 22A and 22B located in the oil feeding system 8, a discharge temperature sensor 11 located on the discharge side of the compressor main body 3, and a controller 9 that computes, when it is estimated that the diversion ratio for the oil cooler 18 is 100% from the temperature sensed by the discharge temperature sensor 11 exceeding a predetermined value Td1, a difference ΔP between the pressure sensed by the pressure sensor 22A and the pressure sensed by the pressure sensor 22B and determines a deterioration state of the oil in reference to the difference ΔP.

摘要： A lubrication system for pneumatic machinery includes a lubricant vessel and a lubricant-control valve connected to a drop-dispensing body to discharge a demanded drop of lubricant inside a sealable drip chamber, which has a pressurized-gas inlet and a lubricated-gas outlet. A lubricator-pad assembly includes a lubricator-pad holder securing a lubricator pad to receive the drop of lubricant. Pressurized gas flows through the holder when exiting the drip chamber. A drop detector detects the demanded drop of lubricant. A controller connects to the drop detector and receives an indication that the demanded drop of lubricant has been detected. When a lubrication-demand tracker of the controller determines, based upon time or flow measurement or a combination thereof, that a lubrication threshold is reached, the controller initiates a drop cycle. If a maximum drop time passes before the demanded drop of lubricant is detected, the controller activates a missing-drop cycle.

摘要： A sensor casing includes a lower case and an upper case that is fixed to an upper part of the lower case. A valve body includes an upper body including an accommodation space in which a sensor casing is disposed and a lower body in which an oil passage is formed. The upper body includes a stopper that prevents downward movement of the oil pressure sensor along a central axis. The sensor casing includes an engagement portion that engages with the stopper to retain the oil pressure sensor in the accommodation space.

摘要： In hybrid electric vehicles having increased battery storage capacity and plug-in capability, electric-only operation of significant duration is available. To supplement lubrication for the electric and mechanical components provided in a fluid circuit by an engine-driven mechanical pump, an electric pump is provided in parallel to the mechanical pump. When the electric pump is operating, a diagnostic can be performed to determine system integrity. According to one embodiment, an actual quantity provide to the circuit is determined; an expected quantity is estimated; and a fault is determined when the actual and expected quantities differ by more than a predetermined amount. The fault may indicate a leak or plug in the fluid circuit or a failure of a component in the fluid circuit.

摘要： A bearing system includes a bearing housing configured to house a bearing and enclosing a free volume for receiving a lubricant, a bearing, a pump configured to pump lubricant into the free volume, a shaft in an opening in the housing rotatably supported by the bearing, an exclusion seal between the shaft opening and the shaft that is repeatably and non-destructively shiftable from a sealing state in which it substantially prevents lubricant from leaving the free volume and a release state in which it allows lubricant to escape between the exclusion seal and the shaft. The exclusion seal is caused to shift by increasing and decreasing a pressure in the bearing housing, and the system includes a controller configured to repeatedly shift the exclusion seal by raising and lowering the pressure in the free volume to continuously maintain a lubricating film between the exclusion seal and the shaft.
