A system for bearing lubrication comprises a bearing; a temperature sensor; a pressure sensor; a lubricant reservoir; a bearing lubrication comprising a pump; a lubricant drainage line; an exhaust fan; and a bearing lubrication controller communicatively coupled to the temperature sensor, the pressure sensor, the pump, and the exhaust fan, wherein the bearing lubrication controller is programmed to execute bearing temperature control logic comprising detecting the temperature from the temperature sensor, determining whether the temperature falls outside an upper pre-defined bound of the temperature, increasing the rate of a lubricant supplied from the pump to the bearing, detecting the fluid pressure from the pressure sensor, determining whether the fluid pressure falls outside an upper pre-defined bound of the fluid pressure within the bearing, and increasing the speed of the exhaust fan to increase a pressure differential along the lubricant drainage line from the bearing to the lubricant reservoir.

To prevent nuisance marine growth in a valve, particularly a ball valve, used to regulate a flow of seawater, a compound for lubricating and preventing nuisance marine growth is provided in the valve. The nuisance marine growth preventing compound includes a substantially uniform mixture of marine grease and an antifouling agent. The compound is introduced into the valve such that the compound is provided between and contacts a valve body and a ball that regulates the flow of seawater within the valve, and inhibits nuisance marine growth at a space between the ball and the valve body which is occupied by the compound.

Embodiments provide an automatic coupling agent feeder, including a housing, a coupling agent storage container, a feed pump, a heating insulation mechanism, a control device, and a discharge mechanism. The discharge mechanism is provided with a discharge port located outside the housing. The control device is electrically connected to the feed pump and the heating insulation mechanism; the feed pump is connected to the coupling agent storage container and the discharge mechanism, respectively, through a convey pipeline, and the heating insulation mechanism is provided outside the convey pipeline between the feed pump and the discharge mechanism. Adoption of the above technical solutions does not need to manually squeeze the coupling agent container, improve the efficiency of the operator, and the comfort of the coupling agent and human contact, in addition, installation of the parts inside the automatic coupling agent feeder internal parts is more compact.

A bearing structure of a turbo charger is provided. The turbo charger includes a semi-float bearing, a rotary shaft. The semi-float bearing is cylindrical and mounted in the bearing housing. The rotary shaft passes through the semi-float bearing and is supported rotatably by the semi-float bearing. The bearing structure includes a slinger wall and a projecting portion. The slinger wall is provided on the rotary shaft so that it is opposed to an end face in the axial direction of the semi-float bearing. The projecting portion projects from at least one of the slinger wall or the end face to the other. The projecting portion is provided in an annular shape along the circumferential direction of the semi-float bearing. The projecting portion includes a cutout portion that links the inner circumferential face side of the semi-float bearing with the outer circumferential face side thereof.

The present invention provides a system for applying an anti-corrosion fluid to an anchor chain or cable. The system may include at least one set of nozzles disposed on the inner periphery of a conduit. Furthermore, at least one flap may be disposed on the inner periphery of a conduit, below the nozzles, for catching and smearing the fluid on the cable. Additionally, the invention may contain a reducer, attached to the bottom of the conduit, that may contain a flap, for catching the excess fluid and smearing the fluid on the cable.

A joining module includes a screw drive, a spindle and a housing. The screw drive includes a tappet that can be moved along a linear movement by a nut. A lubrication unit is arranged on the housing and includes a lubricant in at least one lubrication unit channel. The nut includes at least one nut channel and at least one lubrication point arranged so that the nut can be moved into a lubrication position in which the nut and the lubrication unit are in direct mechanical contact with each other and the lubrication unit channel and the nut channel communicate with each other and so that the lubricant passes from the lubrication unit channel into the nut channel and then to the lubrication point.
