Since the overload rotor sea slide is similar to the low-pressure gear, the test method of the low-pressure gear was considered when drafting the standard, and the test method of the low-pressure gear was considered in accordance with the standards such as G/T2316-88 Hydraulic and Pneumatic Systems and Components Nominal Force System 3. GB/T2347-60 Hydraulic Pumps and Motors Nominal Ranking Series, and full coordination was carried out to make it consistent with relevant national standards and industry standards. Appendix A and Appendix F of this standard are the appendices for reminders. This standard is proposed and managed by Guangzhou Machine Tool Research Institute of the Ministry of Machinery Industry. The drafting of this standard is Guangzhou Machine Tool Research Institute of Qianqiu Pump Factory. The main drafters of this standard are: Zhang Yangjie, Mi Junbiao, Dui Fengxin. 1 Scope

Test method
.1 Test record
5.1.1 The test oil should be 32-30% or more of the filter oil. The pool wave should be finely filtered, and the solid content should not exceed 5BT14C3 l Plan appropriate 16/16: .1.2 Test for the continental temperature should be controlled at 1. = level. 5.1.3 The accuracy of the submeter used for inspection is not less than: 1. = level, or 1. ~ 2 times the rated pressure of the tested pump, 5.1.4 Measure the temperature, the difference is not more than 1.
5.1.5 Recording point location
The setting of the pressure point should be designed as large as possible and as close as possible to the test point, except for the outlet: at: | |tt||Limited value Note: The number of measuring points on the surface with a radius of 1 is not limited. 10 should be evenly distributed.
5.1.6 Test principle See reference A (disturbing record) 5.3 Appearance test
Test 4.5~1.11.
5.3 Running test
Abandon the six-point transfer, start with the complete combat force and gradually load, graded running 5.4 No-load displacement test
Under no-load condition, measure the no-load displacement under the condition of high speed, which should reach 95% of the nominal displacement. 5.5 Efficiency test
Under nominal speed, increase the speed, and measure the flow rate at the plate pressure of about 10%, 55%, and 1CD respectively. Measure the flow rate of the above test pressure points. Note: When checking, only the efficiency test is carried out. 5.6 Self-priming test
Under nominal speed and no-load pressure condition, measure the displacement when the suction port vacuum is equal. Based on this, increase the inlet pressure, and directly measure the displacement drop. Measure its vacuum degree 5.7 Overload test
At the nominal speed, make a continuous operation test at 125% of the rated pressure. The continuous operation time is more than 11 seconds, and there should be no external fullness and abnormality.
JB/T8376-1996
Note: During factory inspection, the continuous operation time is not less than 1 minute. 5.8 Reverse test
Under the condition of constant pressure, make the drum test instrument make 500 consecutive forward and reverse reversing rotations. The reversing frequency is 1 time/min (-forward, reverse times>), and the oil output response time after reversing is not more than 56 seconds. Note: For factory inspection, the instrument makes 10 forward and reverse rotations. 5.9 Noise test
At the nominal speed, measure the peak sound value of at least 6 pressure points from no-load pressure to rated pressure range. 5.10 The internal cleanliness inspection shall comply with the relevant standards. The data after the test shall be sorted and filled in the record table in Appendix B (suggested Appendix).
