Main Hydraulic Pump Motor and Starter Systems Assignment - 3

Main Hydraulic Pump Motor and Starter Systems - Assignment Example The researcher states that the hydraulic powers systems that are currently used in the submarine systems and devices are not only used in powering the devices but also used in operating other systems within the vessels. The submarines also require the use of electric power especially for propulsion as well as operating auxiliary equipment within the vessel. Other than moving stationary light equipment, electricity is often used in instantaneous stopping some equipment such as electric motors. Motors often have the tendency to drift and/or over-travel thereby becoming difficult to control without electricity. Additionally, electrically driven equipment is often noisy and require intense maintenance; therefore, to overcome these shortcomings, the submarine devices are currently designed and manufactured to use hydraulic powering systems including hydraulic motor pumps. Hydraulic motors are the power units of the marine devices; however, they do not generate their own power, but they of ten convert hydraulic power into mechanical energy that is transmitted to other parts of the vessel. Therefore, pumps are the central power supply for the devices using hydraulic systems. The pumps are used to create pressure within the system. Submarine devices usually have different pumps playing different roles. The Waterbury A-end pump is among the pumps using the submarine devices. A rotating shaft operates the Waterbury A-end pump. The rotating shaft may be operated by hand or motor. There are usually three hands driven and three motor-driven Waterbury A-end pumps play different functions to a submarine. They drive the steering system, bow plan system, and stern plan system. Under normal operations, two parts of the entire three systems are used distinctively in the system as steam and motor transmitting oil units while the hand driven part is usually fitted to a larger hand wheel. The Waterbury A-end speed gear operates on a rotation principle where its multiple pistons are o n reciprocating rotations. The gear consists of three basic elements including the socket ring, cylinder barrels, and tilt box. The socket ring is located in ball sockets and it holds seven or nine pistons that connect different rods. On the other hand, the cylinder barrel corresponds to the seven or nine cylinders whereas the tilted box is an inclined socket ring that corresponds to the cylinder barrel.
