Pipe network system leakage judgment method based on flow method

Abstract

The invention belongs to the field of ship hydraulic pipe networks, and particularly discloses a pipe network system leakage judgment method based on a flow method. The method specifically comprises the steps of installing a flow sensor and a constant-pressure water supplementing assembly in a pipe network system; judging whether the ratio of the water supplementing amount to the flow sum of the water supply ends of the equipment set is smaller than or equal to a preset threshold value or not, if yes, enabling the pipe network system to operate normally, and if not, judging that the pipe network system leaks and entering the next step; judging whether the total water outlet flow of the pump set is greater than the sum of the water supply end flow of the equipment set, if so, judging that the water supply main trunk or the equipment set water supply branch leaks, and if not, entering the next step; judging whether the flow sum of the water supply ends of the equipment groups is greaterthan the flow sum of the water return ends of the equipment groups, and if yes, judging that water supply branches in certain equipment group leak; and if not, judging that the water return main trunkor the equipment group water return branch leaks. According to the method, the leakage occurrence part in the pipe network system can be accurately positioned, and the judgment speed and accuracy areimproved.

Description

technical field [0001] The invention belongs to the field of ship hydraulic pipe network, and more specifically relates to a method for judging leakage of a pipe network system based on a flow rate method. Background technique [0002] Large ships contain multi-functional equipment, which must provide specific temperature, flow and water quality to maintain their normal operation. The centralized pipe network system commonly used in the prior art can meet the unified environmental control requirements for cooling and dehumidification of each equipment, and ensure the normal operation of the equipment. Moreover, the centralized pipe network system greatly reduces the repeated investment of the pipe network system and reduces the weight of the pipe network while meeting the heating / cooling needs of each equipment. [0003] However, if there is a leakage problem in a certain part of the centralized pipe network system and cannot be detected in time, it will affect the whole bo...
