The invention is directed to a divider block assembly made from one piece of material. Traditional divider blocks require modular sections so that piston alignment can be calibrated precisely. The current invention uses replaceable pistons and sleeves that are suitable for use at high fluid pressures. The use of these pistons also allows for a single, bodied, one-piece, metal divider body, rather than the conventional multiple block divider blocks, which allows for a more efficient manufacturing method and stronger, more reliable, and more efficient lubricant dispensing system. The use of any of these aspects separately can improve performance, and not all are required in every embodiment.

A lubricating system includes a machine configured to operate in a first operating state and a second operating state; and a heat activated polymer material applied to at least a part of the machine and to remain solid during the first operating state and to soften upon being heated in the second operating state to lubricate the machine. The heat activated polymer material may soften due to increased friction incurred by the machine in the second operating state. A heating element may be operatively connected to any of the machine and the heat activated polymer material. The heat activated polymer material may soften due to being heated by the heating element in the second operating state. An injector may apply the heat activated polymer material to the machine. A channel may direct a flow of the heat activated polymer material as it softens in the second operating state.

A gyrostabiliser having a vacuum chamber assembly is disclosed. The gyrostabilizer can have a flywheel enclosed within a vacuum chamber formed by a housing. The flywheel shaft can be fixed to or integral with the flywheel and located relative to the housing by upper and lower spin bearings which permit rotation of the flywheel about the spin axis.

The invention discloses a high-low pressure lubrication system for a high-horsepower plunger pump, including a high-pressure oil line and a low-pressure oil line, the high-pressure oil line is used for lubricating the connecting rod bearing bushes and the crosshead bearing bushes in the plunger pump, the low-pressure oil line is used for lubricating the crankshaft bearings, the crosshead sliding rails, the reduction gearbox bearing, and the reduction gearbox gear pair in the plunger pump. The beneficial effects are as follows: oil is fed in two passages: a high-pressure oil line and a low-pressure oil line, the high-pressure oil line is used for lubricating the connecting rod bearing bushes and the crosshead bearing bushes, and the low-pressure oil line is used for lubricating the crankshaft bearings, the crosshead sliding rails, the reduction gearbox bearing, and the reduction gearbox gear pair; two oil pumps are employed to supply oil so that the oil supply of each oil line could be better guaranteed, thus better distributing the lubricating oil, and avoiding problems of uneven distribution of lubricating oil caused by excessive lubrication branches and insufficient amount of lubricating oil at each lubricating point, thus enhancing the utilization of lubricating oil, reducing abnormalities; both the high-pressure oil line and the low-pressure oil line utilize two-stage filtration, which can reduce impurities in the lubricating oil and improve the life time of various components in the plunger pump.

A greasing system may use a programmable logic controller. The programmable logic controller, grease pumps, and power system control grease flow into two or more fracked valves on a well are maintained outside of the red zone of the well. The programmable logic controller includes a display that is adaptable to include information related to individual frak valves such as the associated well, the type of valve greasing utilized such as pressure based greasing or stage based greasing and also may include upper and lower limits on pressure and/or amount of grease utilized.

Embodiments of the present disclosure include a remote well servicing system including a control unit and a remote servicing manifold. The control unit further includes a service fluid source and a control system. The remote servicing manifold further includes a fluid input line coupled to the service fluid source, a fluid output line couplable to a well component, and a valve coupled to the fluid input line and the fluid output line, wherein the valve, when actuated, places the fluid input line in fluid communication with the fluid output line and permits delivery of a service fluid from the service fluid source to the well component. The remote servicing manifold also includes a control line coupling the valve and the control system wherein the control system controls actuation of the valve via the control line.
