ANSI HI-10.6-2010 pdf download Air-Operated Pump Tests
10.6.1.1 Objective
This standard provides uniform procedures for mechanical and other pump performance testing and for recording of the test results of air-operated diaphragm and bellows pumps.
10.6.2 Types of tests
This standard contains procedures for the fllowing tests:
a) Test to demonstrate mechanical integrity while pump is in operation; see Section 10.6.4. (Required test.)
b) Performance test; see Section 10.6.5. (Optional test.)
c) Net positive suction head testing; see Section 10.6.7. (Optional test.)
d) Suction lift testing; see Section 10.6.8. (Optional test.)
e) Hydrostatic testing of pressure-retaining components; see Section 10.6.9. (Optional test.)
f) Noise measurement; see Section 10.6. 10. (Optional test,)
10.6.3 Definitions
The fllowing terms and symbols are used to designate test parameters used in connection with pump tests.
10.6.3.1 Symbols
See Table 10.6.3.1.
10.6.3.2 Subscripts
See Table 10.6.3.2.
10.6.3.3 Rated condition point
Rated condition point applies to the rate of flow (capacity), discharge pressure, suction pressure, NPIP/NPSH, and air consumption of the pump as specified at a specific rate of flow. Air-operated reciprocating pumps are normally purchased from a standard performance curve. There normally is no single “rated” flow rate.
10.6.3.4 Volume (standard units)
The standard unit of volume shall be as follows:
a) Metric – cubic meter.
b) US customary units – US gallon or cubic foot.
The specific weight, r (gamma), of water at a temperature of 20。C (68 °F) shall be taken as 9.79 kN/m3 (62.3 Ib/ft3). For other temperatures, proper speific weight corrections shall be made, using values from the ASME steam tables.
10.6.3.5 Stroke length (4)
The distance traveled in one complete unidirectional motion of the diaphragm or bellows and connecting rod.
10.6.3.6 Cycle
One complete motion of the diaphragms or bellows. Two strokes equal one cycle.
10.6.3.7 Cycle rate (川)
The number of cycles in a given unit of time, usually one minute.
10.6.3.8 Rate of flow (capacity) (Q)
The volume of liquid delivered per unit of time at suction conditions. It assumes no entrained gases at the stated operating conditions.
