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.Overfilling the recovery cylinder
c.Freezing the condenser water
d.Bursting the rupture disk set near 15 psig
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.
