A sound stuffing box installation is critical to safety because failure can admit a catastrophic volume of water into the boat. Marine- duty hose clamps secure the hose to the stern tube and the stuffing box. In many small fiberglass boats, for example, the stuffing box is mounted inboard near the point the shaft exits the hull.Ī special purpose heavy- duty rubber hose attaches the stuffing box to a stern tube, also called a shaft log, that projects inward from the hull. The stuffing box prevents sea water from entering the boat's hull. Other types of sealed connections without moving parts are also sometimes called glands for example, a cable gland or fitting that connects a flexible electrical conduit to an enclosure, machine or bulkhead facilitates assembly and prevents liquid or gas ingress. Likewise the shaft of a handpump or wind pump is sealed with a gland where the shaft exits the borehole. The linear seal around the piston rod of a double acting steam piston is also known as a gland, particularly in marine applications. The gland at the rotating shaft of a centrifugal pump may be packed in a similar way and graphite grease used to accommodate continuous operation. The gland nut allows the packing material to be compressed to form a watertight seal and prevent water leaking up the shaft when the tap is turned on. The most common example is in the head of a tap (faucet) where the gland is usually packed with string which has been soaked in tallow or similar grease. Stuffing box components are of stainless steel, brass or other application- specific materials. Through tightening it onto the stern tube, the packing is compressed, creating a seal against the shaft. Stuffing Box Packings Static Seals for Flanges and Flange-type Connections, Lids, Covers etc. Stuffing Box Machind Drawing.pdf To download full version "Stuffing Box Machind Drawing.pdf" copy this link into your browser. The shaft is wrapped by the packing and put in the gland nut. The packing is inside the gland nut and creates the seal. It will also have packing nut threads or a gland nut. A stuffing box is an assembly which is used to house a gland seal. Everybody know that stuffing box is a important mechanical device, which is used to prevent oil leakage in engine, In this design first time i try drawing section in.
