摘要： A fluid system for a wind turbine, which is particularly beneficial when the wind turbine is operating at low power, such as during idling operational mode. Fluid accumulates in a fluid storage device before being released intermittently, for example by fluid bursts or pulses, to one or more consumer units, including but not limited to bearings. The fluid system advantageously enables fluid, such as lubricant, to be sufficiently distributed to the one or more consuming units even if the pump used to supply fluid to the consuming units is operating at low power.

摘要： A system and methods according to which a controller communicates control signals to a first frac leg, which includes a wellhead operably associated with a first wellbore, a valve operably coupled to the wellhead, opposite the first wellbore, a frac line operably coupled to the wellhead, and a zipper module operably coupled to the frac line, opposite the wellhead. The first frac leg includes a first sub-controller that receives control signals from the controller. A grease system lubricates the first frac leg and the zipper module. The grease system includes a second sub-controller that receives control signals from the controller. A second frac leg is operably associated with a second wellbore. The second frac leg includes a third sub-controller that receives control signals from the controller. The first, second, and/or third sub-controllers may receive control signals from the controller via a communication bus.

摘要： A pump housing includes an integral vent flow path extending between a low-pressure region and the reservoir. The vent path provides fluid communication between the downstream side of a throat seal dividing the low-pressure region from a high-pressure region and the reservoir. Lubricant flows through the vent path from the reservoir to the low-pressure region to provide lubrication to the throat seal.

摘要： The current invention includes manifold having multiple outputs and at least one input for lubricant to be pumped at high pressure from a skid or trailer to a particular frac valve when the valve requires lubrication. Generally such frac valves require lubrication on an hourly schedule or less. Each output port on the manifold is fitted with an on/off valve that allows remote operation such as pneumatic, hydraulic, electro-pneumatic operation, or other known remote operation system. The pump or pumps are also configured for remote operation. A controller is then provided so that each circuit allows, upon command, lubricant to be pumped from the lubricant reservoir, through the pump, to the manifold, through each remotely operable valve, via each output port, through an appropriate rated hose, then to the lubrication or other port on each frac valve. Generally, once connected each frac valve remains connected to the system to allow the operator to cause lubricant to flow to each valve upon command. The controller may also provide a safety cutout so that the system will only provide pressurized lubricant with the controller in the operator's possession while the operator continuously actuates the appropriate switch.
