Type III — Low-Pressure第 200 / 240 题
The main safety concern that sets the 10 psig pressurization limit on low-pressure appliances is:
a.Damaging the compressor windings
b.Bursting the 15 psig rupture disk
c.Freezing the condenser water
d.Overfilling the recovery cylinder
解析
The 10 psig limit exists to keep test pressure safely below the rupture disk, which typically bursts near 15 psig to protect the low-pressure shell. Exceeding 10 psig risks rupturing the disk and releasing the charge. This is why nitrogen leak testing on these machines is done at low pressure.
