Selection from Flow Rate Characteristic Graph
Required specifications example:
Find the pilot air pressure and pilot air consumption for a discharge rate of 15 L/min and a discharge
pressure of 0.14 MPa. <The transfer fluid is fresh water (viscosity 1 mPa·s, specific gravity 1.0).
If the total lifting height is required instead of the discharge pressure, a discharge pressure of 0.1
MPa corresponds to a total lift of 10 m.
Selection procedures:
1. First mark the intersection point for a discharge rate of 15 L/min and a discharge pressure of 0.14
MPa.
2. Find the pilot air pressure for the marked point. In this case (cycle: 3 Hz), the point is between the
discharge curves (wavy lines) for SUP = 0.2 MPa and SUP = 0.3 MPa, and based on the
proportional relationship to these lines, the pilot air pressure for this point is approximately 0.22
MPa.
Caution
1. These flow rate characteristics are for fresh water (viscosity 1 mPa·s, specific gravity 1.0).
2. The discharge rate differs greatly depending on properties (viscosity, specific gravity) of the fluid
being transferred and operating conditions (lifting range, transfer distance), etc.
