Water level control in regional river vessels using automatic rule-a-matic attached to the rule basement pump

Abstract

The economic impetus caused by the need to renew the Brazilian fleet of vessels, together with the growth of activities in the sector, collided with the major obstacle of the lack of construction structure in the country, due to the high degree of obsoleteness of the industrial park of the shipyards, including the ship parts industries. The most economically viable solution found by shipowners and operators was to order vessels designed and, when possible, also built abroad, which would not generate jobs and income for Brazilian workers and would not place the national industry within the current level of technological development of the international shipbuilding. The purpose of the present work is to use the automatic RULE-A-MATIC coupled to the RULE bilge pump so that the captain and engineer can be alerted about possible unexpected flooding at the bottom of the vessel. A comparison was made between the main pumps available on the market in order to justify the choice for the RULE pump, as well as describing each of the materials used for the construction of the prototype. The results indicate that, at the end of the prototype construction and after several tests, as well as reading and comparison about other bilge pumps, it is pointed out that the choice of the RULE 500 GPH pump (Galão per Hour) is due to the fact that most medium and large wooden vessels use a centrifugal pump coupled to the vessel's engine for this removal in motion and, when the vessel is anchored, the engineer starts the HONDA 5.5 HP engine, to remove water from the bottom of the vessel. vessel. However, we use the RULE pump to avoid physical wear and tear by the driver and also a higher fuel consumption, as well as a lower energy cost on the vessel. Being this pump market leader, featuring better quality, durability and reliability.
