摘要： The disclosure relates to a carriage apparatus for carrying a tool string down a wellbore in a wireline logging, and an orientation apparatus and hole finder device for a wireline logging tool string. In some embodiments the carriage includes a protection structure which extends longitudinally around a wheel of the apparatus to thereby prevent a side of the wheel from contacting a wall of the wellbore. In some embodiments an orientation apparatus and hole finder are arranged so that the orientation apparatus orientates the hole finder device in the wellbore so that a tip of a nose section of the hole finder is elevated above a low side of the wellbore by a height and offset from and above a longitudinal axis of the tool string.

摘要： A centerfill assembly for a lubricant reservoir includes a hollow tube for receiving lubricant from the top of the reservoir and loading the lubricant into the reservoir near the bottom of the reservoir. Loading the lubricant near the bottom of the reservoir introduces lubricant near where the stirring paddles mix the lubricant and near where the lubricant is loaded to the lubricant pump. Adding the lubricant near where the pumps load and near the stirring paddles helps to eliminate air pockets in the lubricant. In addition, having the centerfill rod minimizes exterior plumbing and allows for the mounting of valves on the fill line.

摘要： A control apparatus controls driving of an oil feeding unit. The oil feeding unit includes a piezoelectric body that deforms in response to a voltage applied thereto, and a reservoir to store lubricating oil. The capacity of the reservoir changes in accordance with deformation of the piezoelectric body so as to discharge lubricating oil from the oil feeding unit. The control apparatus includes N driving circuits 71a to 71n configured to apply voltages to the piezoelectric body (where N is an integer equal to or greater than two). The N driving circuits 71a to 71n are connected in parallel to the piezoelectric body. During oil feeding, the control apparatus uses a predetermined number of the driving circuits selected from the N driving circuits. The predetermined number is smaller than N.

摘要： A protection mechanism for a lubricant reservoir is mounted within a valve protection chamber disposed on an actuator. The protection mechanism includes a valve actuating plate and an elastic member biasing the valve actuating plate upwards. The actuator is pushed upwards by a rising level of lubricant as the lubricant reservoir is filled. When the reservoir is full, the actuator causes the valve actuating plate to contact a valve stem. The valve actuating plate pushes the valve stem up to shut off a flow of lubricant to the reservoir through the shut off valve. During an overfill event the actuator shifts upward due to the rising level of the lubricant in the reservoir. As the actuator shifts upward, the elastic member compresses such that valve actuating plate remains static relative to the lubricant reservoir as actuator rises.

摘要： A lubrication system comprising a motor, a positive displacement pump driven by the motor, a lubricant container in fluid communication with the positive displacement pump and at least one lubricant outlet in fluid communication with the lubricant container. The positive displacement pump is arranged to carry out at least one discharge stroke to dispense lubricant from the at least one lubricant outlet when the lubrication system is in use. The lubrication system also comprises a control unit that is arranged to determine an amount of lubricant that is dispensed from the lubricant container via the at least one lubricant outlet when the lubrication system is in use. The control unit is arranged to monitor current supplied to the motor to obtain a motor current signal, and to determine a number of the discharge strokes from the motor current signal.

摘要： A rolling bearing apparatus includes: a bearing portion having an inner ring, an outer ring, a plurality of balls, and a cage; and a lubrication unit that is provided adjacently to an annular space formed between the inner ring and the outer ring and that has a pump that feeds a lubricant into the annular space. The pump has a main body portion having an internal space in which the lubricant is retained and being open at one end of the main body portion, a metal diaphragm fixed to a fixation portion that is a part of the main body portion so as to close the opening of the main body portion, and a piezoelectric element fixed to the diaphragm. At least the fixation portion of the main body portion is formed of metal, and the fixation portion and the diaphragm are fixed together by metal joining.

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.
