摘要： System, apparatus, and method for delivering grease to process valve(s). The system generally includes a grease cylinder to which grease is delivered, a piston, an actuator, and a first process valve. The piston extends at least partially within the grease cylinder. The actuator strokes the piston within the grease cylinder to meter a first amount of the delivered grease to the first process valve. The actuator comprises a power cylinder within which the piston extends. The piston comprises a head portion slidably disposed in the power cylinder and dividing the power cylinder into first and second chambers. The head portion has a first cross-sectional area. The piston includes another portion contacting the grease in the grease cylinder and having a second cross-sectional area smaller than the first cross-sectional area. The actuator may also meter a second amount of the delivered grease to a second process valve.

摘要： Methods and apparatus according to which a first valve is opened, or kept open, the first valve being part of a wellhead including a flow component above the first valve. The method may further include detecting a state of the first valve and, in response to detecting the state of the first valve, metering an amount of grease to the first valve. In addition, or instead, the method may further include opening, or keeping open, a second valve, the second valve being operably coupled to the wellhead and positioned above the flow component, and, after opening, or keeping open, each of the first and second valves, detecting whether the second valve is open or closed, in response to detecting that the second valve is open, preventing the first valve from being closed, and in response to detecting that the second valve is closed, allowing the first valve to be closed.

摘要： A mechanical machine can include one or more kinematic linkages having kinematic joints that movably couple first and second rigid links and can include an automatic lubrication system to lubricate the kinematic joints. In an aspect, the automatic lubrication system is configured to monitor operational aspects of the machine such as machine operational data and geometric position and to dynamically determine timing and/or quantity of lubricant to direct and introduce to the kinematic joints.

摘要： An example lubricant coating device includes a rotatable applicator to apply lubricant from a solid lubricant source to a member to be coated, and a supporting device to support the solid lubricant source in a contact state with the rotatable applicator. The supporting device changes a supporting angle of the solid lubricant source relative to the rotatable applicator when a consumption of the solid lubricant source reaches a consumption threshold.

摘要： A lubrication system comprises a lubricant reservoir, a motorized pump, a follower plate, a stationary rod, a movable sleeve, and a flexible connection. The motorized pump is disposed to pump fluid from the lubricant reservoir to lubricant work lines. The follower plate is situated within the lubricant reservoir. The stationary rod has a colored indicator portion. The movable sleeve disposed concentrically about the stationary rod. The flexible connection extends between the follower plate and the stationary colored rod, such that the flexible connection pulls the movable sleeve away from the stationary rod to reveal the colored indicator portion as the follower plate drops towards a bottom of the lubricant reservoir.

摘要： A method includes providing a bearing housing configured to house a bearing, the bearing housing enclosing a free volume for receiving a lubricant and including a shaft in a shaft opening, filling the free volume with the lubricant, providing an exclusion seal between the shaft opening and the shaft, the exclusion seal being repeatably and non-destructively shiftable from a sealing state and a release state, the exclusion seal being shiftable from the sealing state to the release state by increasing a pressure in the bearing housing to above a first level and being shiftable from the release state to the sealing state by decreasing the pressure to below the first level; and continuously maintaining a film of the lubricant between the exclusion seal and the shaft by repeatedly causing the pressure of the lubricant in the free volume to rise above and fall below the first level.
