Function test method for pressure accumulating block assembly of low-speed machine for ME-B type ship

Abstract

The invention discloses a function test method for a pressure accumulating block assembly of a low-speed machine for an ME-B type ship. The function test method comprises the following steps: testing each one-way valve, a 212-pressure reducing valve, a 210-electromgantic valve, a 213-pressure reducing valve, a 311-pressure reducing valve and a 315-ball valve on the pressure accumulating block assembly in sequence; and judging the functional validity of the pressure accumulating block assembly according to different test expressions. The pressure accumulating block assembly is ensured to work normally in subsequent use through the test, or a fault point is diagnosed through the test when the pressure accumulating block assembly is maintained. According to the pressure accumulating block assembly function test method for the low-speed machine for the ME-B type ship, the functions of the pressure accumulating block assembly of the low-speed machine for the ME-B type ship can be verified comprehensively and accurately; a failure point can be found out and repaired timely; the quality of a product is ensured; and a high-efficiency diagnosis method is also provided for after-sale maintenance.

Description

technical field [0001] The invention belongs to the field of ME-B type marine low-speed engine, and in particular relates to a test method for a pressure accumulator block assembly in a hydraulic power supply system of the low-speed engine. technical background [0002] In the ME-B marine low-speed engine, many systems such as the fuel supply system and the lubricating oil system adopt the hydraulic power mode, and the main function of the pressure accumulator block assembly in the low-speed engine is to transfer the hydraulic oil pressurized by the hydraulic pump station. Stable delivery to each system. If the accumulator block assembly fails during use, it will affect the operation of the entire low-speed machine. Therefore, the ability to check the performance of the pressure accumulator block assembly before installation and use will help reduce the possibility of malfunctions in use. In addition, if the fault point can be found in time after a fault occurs, the mainte...
