The invention provides an automatic pump stopping device of a marine engine room oil tank. The automatic pump stopping device acts between an oil tank and marine equipment and comprises a first oil pump and a mechanical pump stopping mechanism, an oil inlet pipe is connected between one end of the oil tank and an inlet of the marine equipment, an oil outlet pipe is connected between the other endof the oil tank and an outlet of the marine equipment, the first oil pump and the mechanical pump stopping mechanism are arranged on the oil inlet pipe, and the mechanical pump stopping mechanism is used for controlling the first oil pump to stop when the oil pressure exceeds the range and dividing flow of high-pressure oil. By installing the mechanical pump stopping mechanism on the oil inlet pipe, mechanical control over oil pressure is achieved, and the oil pressure in the pipe is stabilized within the standard range.
Description
technical field [0001] The invention relates to the technical field of ships, in particular to an automatic pump stop device for an oil tank in an engine room of a ship. Background technique [0002] In marine technology, the oil tank in the engine room mainly provides lubricating oil or cooling oil for the marine engine through the oil pump. The start and stop control of the oil pump is controlled by the main engine control system. The control method is: the oil pump is set to the self-injection mode on the control system , when the oil pressure of the oil pump is lower than the lowest threshold value, the oil pump will automatically start running; when the oil pressure is higher than the highest threshold value, the oil pump will automatically stop running. [0003] However, when the host control system breaks down, such as crash, all the equipment controlled by the host control system will not be automatically adjusted or switched. If the oil pressure is too high and not ...
