Abstract
An equipment inspection system performs compressed air leakage inspection on a plurality of pieces of pneumatic equipment that are connected to pipes, or pipe joints that connect the respective pipes and the plurality of pieces of pneumatic equipment, has a first branched pipe and a second branched pipe. A flow rate measurement device is provided in the second branched pipe. The flow rate measurement device measures the flow rate of the compressed air flowing in the second branched pipe. A fluorescent solvent providing part is provided in the first branched pipe. A fluorescent solvent is supplied to the pipe from the fluorescent solvent providing part.
Claims8
An equipment inspection system for inspecting whether there is a compressed air leakage location in a plurality of pieces of pneumatic equipment connected to each of a plurality of second sub-pipes branching from each of a plurality of first sub-pipes branching from a pipe through which compressed air flows, or whether there is a compressed air leakage location in a pipe joint connecting each of the plurality of second sub-pipes and each of the plurality of pieces of pneumatic equipment with each other, comprising:
- a first branch pipe that branches from each of the plurality of first sub-pipes at a location upstream of the pipe joint and merges with each of the plurality of first sub-pipes at a location upstream of the pipe joint;
- a fluorescent solvent supply portion that is provided for the first branch pipe and supplies a fluorescent solvent to the plurality of second sub-pipes via each of the plurality of first sub-pipes;
- a fluorescent solvent collection portion that is provided downstream of the fluorescent solvent supply portion and collects the fluorescent solvent supplied from the fluorescent solvent supply portion;
- a second branch pipe that branches from each of the plurality of first sub-pipes at a location upstream of the pipe joint and merges with each of the plurality of first sub-pipes at a location upstream of the pipe joint;
- and
- a flow rate measurement device that is provided for the second branch pipe and measures a flow rate of compressed air flowing through the second branch pipe;
- a first valve that is, at each of the plurality of first sub-pipes, arranged downstream of a location where each of the first branch pipe and the second branch pipe branches and arranged upstream of a location where each of the first branch pipe and the second branch pipe merges;
- a second valve that is provided for the first branch pipe;
- and
- a third valve provided for the second branch pipe,
- wherein compressed air selectively flows through any of each of the plurality of first sub-pipes, the first branch pipe, or the second branch pipe by the first valve, the second valve, and the third valve being opened and closed, and
- compressed air having flowed through any of each of the plurality of first sub-pipes, the first branch pipe, or the second branch pipe is supplied to the plurality of pieces of pneumatic equipment via the plurality of second sub-pipes.
