Test performance: At the rated flow rate, the pressure is adjusted through the pressure regulator chamber, and the adjusted pressure tolerance is P = P rated ± 0.8% (the pressure and tolerance to be adjusted for different types of pressure regulators are shown in Table 2.1); The rated flow rate is adjustable in the range of 40-130 L/h, and the rated pressure P is adjustable in the range of 2.0-4.0 bar. Equipment capability index: Cm, Cmk ≥ 1.67; Scrap rate caused by equipment: ≤ 0.03%; Cycle time: ≤ 25s.
