Abstract
Test liquid (3) including thermosetting resin is injected from an injection valve (2). Light (L) is irradiated to a spray (6) of the test liquid (3) injected from the injection valve (2) as a treatment for producing a hardening effect to the thermosetting resin. Liquid drops in the spray (6) are hardened and collected as particles. Spray characteristics such as a particle size distribution of the injection valve or the like are analyzed by using the collected particles.
Claims17
A spray measurement method comprising:
- a step of injecting test liquid including curable resin from an injection valve;
- a step of hardening liquid drops in a spray of the test liquid injected from the injection valve into particles by applying treatment for producing a hardening effect of the curable resin;
- and
- a step of analyzing spray characteristics of the injection valve using the particles hardened.
1 more element
A spray test apparatus comprising:
- a test liquid supply device which is configured to supply a test liquid including curable resin to an injection valve;
- and
- a hardening device which is configured to harden liquid drops in a spray of the test liquid injected from the injection valve into particles by applying treatment for producing a hardening effect to the curable resin, to the spray, wherein
- the test liquid supply device is configured to supply to the injection valve the test liquid containing the curable resin in which a hardening effect is produced by irradiation of an energy beam, and
- the hardening device is configured to irradiate the energy beam to the spray as the treatment.
