27、 MATERIALS (ASTM)ASTM-B633 Zinc on Iron the flow may be measured in the low pressure side of the discharge line provided that efficiency calculations compensate for fluid compressibility. Note that as discharged pressure is increased, the compressibility of the fluid reduces apparent pump efficiency
28、 even if pump performance itself does not change. Variation in bulk modulus of the fluid will therefore appear as a variation in pump efficiency.3.3.12 Pressure pulsations: Pressure pulsations are the oscillations of the discharge pressure, occurring during nominally steady operating conditions, at
29、a frequency equal to or higher than the pump drive shaft speed. The amplitude of pressure pulsations shall be determined by the test procedure of 4.3.2.1.6.4. These pulsations shall not exceed 300 psi (2100 kPa) under any condition, or a pressure band specified by the detail pump specification. The
30、pump shall be tested in the circuit which simulates the actual system in which the pump is to be installed, as defined in the detail pump specification. The system volume shall be simulated using tubing of the discharge line diameter. A tubing line length whose natural frequency is resonant with pul
31、sation frequency shall be avoided.Copyright SAE International Provided by IHS under license with SAENot for ResaleNo reproduction or networking permitted without license from IHS-,-SAE AS19692 Revision A- 9 -FIGURE 1.

34、ressure is reduced from rated discharge pressure to maximum full-flow pressure and vice versa.3.3.13.1 Response time: The response time of the pump shall be the time interval between the instant when an increase (or decrease) in discharge pressure change initiates; and the subsequent instant when th
35、e discharge pressure reaches its first maximum (or minimum) value. In figures 3 and 4, the time intervals T1and T2are the response times of the pump as a function of the system impedance. The oscillographic trace of discharge pressure versus time shall be employed as the criterion of movement of the
36、 flow control mechanism. All pump models when operating at rated inlet temperature at rated speed and in a circuit whose system impedance as specified in 4.3.2.1.6.1.1 for response tests, shall have a response time of .050 seconds maximum unless otherwise specified in the detail pump specification.3
37、.3.13.2 Stability: The stability of the pump shall be the freedom from persistent or quasi/persistent oscillation or “hunting“ of the flow control mechanism at any frequency that can be traced to the pump flow control means. The oscillographic trace of discharge pressure versus time shall be employe
38、d as the criterion of the stability. All pump models, under any operating condition within the limits established in the detail pump specification and at any speed greater than 50 percent of rated speed, after being disturbed from steady-state operation by a change in flow demand or a change in pump
39、 speed, shall recover steady-state operation (other than permissible pressure pulsations as specified in 3.3.12), within one second after initial response to that change in flow demand. When required by the contracting activity, the pump manufacturer shall provide pump data to permit the system desi
40、gner to integrate pump dynamic performance into his complete pump and system analysis.3.3.13.3 Maximum transient pressure: The maximum transient pressure shall be the peak value of the oscillographic trace of discharge pressure, made during operation of a pump, as specified in 4.3.2.1.6.2 and measur
41、ed as shown on figure 3. The maximum transient pressure, as determined in the transient pressure test specified in 4.3.2.1.6.2, shall not exceed 135 percent of rated discharge pressure for systems up to 5000 psi (34,500 kPa) and 120 percent for systems above 5000 psi or as defined in the detail pump
42、 specification.3.3.13.4 Depressurization: When it is a requirement of the detail specification that the pump be depressurized, either automatically or remotely as by an electrical signal, the depressurization control shall not, when deenergized, interfere with the normal operation of the variable fl
43、ow control. The detail pump specification shall specify the requirements of qualification tests and quality conformance tests of the depressurization control. When full-flow depressurization is required, the detail pump specification shall identify the minimum and maximum operating pressure.3.3.14 B
44、alance: The moving parts of the hydraulic pump shall be balanced and the pump shall not vibrate in such a manner as to cause failure of any part in the pump or drive mechanism at speeds up to and required overspeed.

47、d to adjust the flow control mechanism to cause zero flow to occur at rated discharge pressure. This adjustment shall be preferably continuous, or acceptable in steps of less than one percent of rated discharge pressure over a minimum range of from 95 percent of rated pressure to 105 percent of over
48、pressure. The adjustment means shall be capable of being positively locked, and it shall be possible to accomplish adjustment and locking by the application of standard hand tools.
