Volumetric piston and rock pumps

Volumetric piston and rock pumps.The principle of operation of the piston pump is to move the liquid (or gas ) under the action of the piston performing reciprocating motion . In this case, there is an alternation of two successive processes : suction and discharge . Suction is a process where the movement of the…

The concept of aggregation of marine equipment

The concept of aggregation of marine equipment. Regarding the creation of such equipment structures, when mechanisms, apparatus and devices that work together and are closely interconnected according to the nature of their operation, are assembled into one equipment and mounted on a common base frame or frame. The main condition for aggregation is high shop…

Main parts of crank mechanisms

Main parts of crank mechanisms.Krivoshinu – a nut-gear mechanism serves to convert the reciprocating motion of the piston into a rotary motion. Crankshaft and piogo shaft (in steam engines or in internal crane engines). In machines such as piston pumps, compressors, the crank-and-rod mechanism serves to convert the rotational motion of the crank shaft into…

Anchor mechanisms

Anchor mechanisms.The following anchor mechanisms are used on sea vessels: anchors (half-brushes) anchor or anchor. mooring spiers and anchor – mooring winches. The anchor mechanisms serve to release the anchor and the anchor chain when the ship is anchored; anchoring the anchorage during anchorage; Anchoring – pulling the ship to the anchor, selecting the chain…
