Abstract

The invention relates to the technical field of sealing experiments and relates to a n air tightness test device for a piston assembly The device comprises a machine frame, wherein he upper end of thelong-strip-shaped water tank is open, the machine frame is connected to one side of the long-strip-shaped water tank side by side. The device also comprises a high-position operation platform arranged on the machine frame. A compressed air main pipe is fixed to the other side of the long-strip-shaped water tank in the length direction of the long-strip-shaped water tank. A plurality of compressedair output branch pipes is distributed on the compressed air main pipe at intervals. An output port of the compressed air output branch pipe is connected with a retractable coiled hose, a compressedair switch is arranged on the compressed air output branch pipe, and a pressure gauge is arranged on a pipeline between the compressed air switch and the output port of the compressed air output branch pipe. According to the invention, the efficiency and safety of the air tightness test of the piston assembly are improved.

Description

technical field [0001] The invention relates to the technical field of sealing experiments, in particular to an air-tightness testing device of a piston assembly. Background technique [0002] The piston assembly of the main engine of the ship needs to be tested for air tightness after assembly. The traditional test method is to place 6 to 7 pistons upright in a large water tank at the same time. Due to the high height of the piston assembly, it is necessary to use a mobile climbing platform , the pump pressure test is carried out for each piston, and the compressed air interface is also inserted one by one. The pump pressure inspection can be carried out only when the rack is installed. This test method is time-consuming and labor-intensive, and its safety cannot be guaranteed. [0003] Therefore, it is necessary to find an airtight test method for the piston assembly of the ship's main engine with high test efficiency and good safety. Contents of the invention [0004...
