Description

Technical Field

[0001] The utility model relates to the technical field of special tools, in particular to a disassembly and assembly tool for a pressure accumulator. Background Art

[0002] The accumulator is a component that stabilizes the hydraulic oil pressure on the HCU unit, HPS unit and ALPHA injector in a two-stroke low-speed diesel engine. The hydraulic oil on the diesel engine is pressurized to 200 bar or 300 bar by the engine pump and electric pump of the HPS unit, and is used for the hydraulic oil of the fuel pump, exhaust valve actuator and ALPHA injector on the HCU unit. The hydraulic oil fluctuates during the operation of the engine pump and electric pump. The accumulator is installed behind the HPS pump, on the HCU unit and on the hydraulic oil channel of the ALPHA injector.
