Each hydraulic motor assembly shall be subjected to the tests specified in table lII. 4.5.3 Performance. 4.5.3.1 Startm g torque. To determine conformance to 3.4.1, the motor shaft shall be exernally rotated thro

37、ugh one revolution at a rate less than one rpm. The difrential pressure across the motor ports shail be mallrtained at a value not to exceed 2300 psi. The torque measure at any point in the rotation shall not be less than 30 lb-in. 4.5.3.2 Runnino torque. To determine conformance to 3.4.2, the torqu

38、e shail be measured at the output shaft of the motor, running at a speed of 3000 rpm with a differential pressure of 2300 psi. The torque shaU be not less than 30 lb-in. 4.5.3.3 Friction torque. To dethe confiormance to 3.4.3, the torque required to rotate the unit at a speed of 6 rpm shall be measu

39、red at the output shaft. The torque required shall not exceed 2.5 lb-im (0.28 N-m). 4.5.3.4 Holdina toraue. To determine conformance to 3.4.4, apply an overhauling torque of 24 bin to the motor shaft. Connect the drain port to the inlet port thni a 10 psi check valve and block the outlet port. Fill

40、all hydrdc lines with hydraulic fluid. The motor shaft shall not rotate more than 200 revolutions in 10 minutes with a 24 lb-in (2.7 N-m) torque applied. 12 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-flIL-PRF-bZ3b5C m 7L79Ob 2054594 8bb m 4.5.3.

41、5 Intermittent torque. To determine conformance to 3.4.5, the outlet port of the motor shall be connected to the drain through a 2700 psi relief valve. The inlet port shall be supplied hydraulic fluid through an anti-cavitation check valve from the drain. The case drain shall be connected to drain t

42、hrough a 20 psi (6.9 kPa) check valve. The torque shall be sufficient to cause flow through the 2700 psi relief valve. Repeat for a total of 3000 cycles. The motor shall be capable of meeting the performance requirements of 3.4 after the test. 4.5.3.6 Attitude. Conformance to 3.4.6 shall be verified

43、 by tests on a motor with the mounting flange in at least 3 positions: horizontal; vertical, up; and vertical, down. 4.5.3.7 Resisting load. To determine conformance to 3.4.7, a load of 30 lb-in shall be applied to the motor shaft tending to turn the motor shaft in opposition to the direction establ

44、ished by the hydraulic flow (resisting load). The motor shall be run at 3000 rpm. The pressure differential shall not exceed 2300 psi (see 3.4.2). 4.5.3.8 Cvlinder block lift. To determine conformance to 3.4.8, the motor shall be operated at 9000 rpm for 10 seconds in each direction with no load on

45、the shaft. There shall be no cylinder block lift as evidenced by the absence of excessive case drain flow. 4.5.3.9 Volumetric efficiency. To determine conformance to 3.4.9, the shaft shall be loaded to impose an operating pressure on the inlet port, the motor speed shall be varied between 1500 and 6

46、000 rpm and the volumetric efficiency shall not be less than 95%. 4.5.3.10 Intermittent speedendurance. To detennine conformance to 3.3.4 and 3.4.10, the motor shall be started with a resistive load of 22 lb-in (2.5 N-m) applied to the output shaft. The motor shall be operated at this load for 6 sec

47、onds at 5000 rpm and then stopped. The time required to change direction of motor rotation shall not be less than 1 second nor more than 1 O seconds. A sequence of 5 periods of operation in each direction followed by a nonoperating period of not less than 2 minutes shall comprise one test cycle, wit

48、h a resistive load. The motor shall be acted upon by an overhauling load in the identical manner as the resistive load. The overhauling load test cycle shall be the same as for the resistive load test cycle. Perform at least 5000 cycles in accordance with table II (see 6.3). 4.5.3.11 Leakage. Operat

49、ing fluid for leakage tests shall be supplied at a temperature of 130F (54C) (see 3.4.11). 4.5.3.1 1.1 Running leakage test. To determine conformance to 3.4.11.1, with the motor shaft free to rotate, apply 1000 i25 psi (6900 i170 Ha) to one port and throttle the output to achieve approximately 10 rpm motor shaft speed. Apply 100 +i0 psi (689.5 569 kPa) to the case drain. 13 Provided by IHSNot for ResaleNo reproduction or networ
