Foreword

This standard is GB/T 14096-1993 "pump test bench test methods" amendments. This standard is not equivalent to ISO 4008-1. 1980 "Road vehicles - Fuel injection pump testing dynamic conditions." According to the provisions of this standard GB/T 1.1-2000 preparation, technical content and some editorial changes were made. This standard compared with GB/T 14096-1993, the major technical changes as follows. --- In Chapter 1 Scope, the abolition of the "This standard applies to the maximum amount of oil per cycle is not more than 300mm3"; --- In Chapter 2, normative references are used currently valid standards; --- In 3.1.3, add the formula (2) in the shape description parameter Δ 1; --- In 3.2.3, add the formula (4) in the shape description parameter Δ 2; --- In 3.9.2 and 3.12, describes the specific method for reading when oil, the abolition of the "inverted cup oil and fuel should be sinking time GB/T 5770 provisions "; --- In 3.10.1, Table 1 increased the table title; --- Pump test bench factory commissioned by the reliability test "Fuel Injection production enterprises," add "or third-party legal detector Construct a "; --- In 3.11, Table 2 adds table title; --- In 3.12, the test bench with the calibration fluid, high pressure tubing, standard fuel pump and injectors increased the standard of the corresponding standard number; --- In 3.12, use the "test bed with a standard fuel injector" instead of "test bed with the injector"; --- In E. 1.2, increasing the filter Standard GB/T 5330; --- In Table E. 1, to increase the recording G1 and G2. This standard appendix A ~ Appendix E are normative appendix. This standard replaces GB/T 14096-1993. This standard is proposed and managed by China Machinery Industry Federation. This standard is mainly drafted by. Wuxi Institute of grease nipple pumps, Taishan Jinshi Machinery Co., Ltd., Precision no 锡托福莱尔 Machinery Co., Ltd. Tai'an City Hite machinery manufacturing limited liability company. The main drafters of this standard. Zhuxi Fen, Wang group, Fang Yunjia, Zhang Jizhong. This standard replaces the standards previously issued as follows. --- GB/T 14096-1993. Injection Pump Test Bench Test Method

3 Test Method

3.1 injection pump test stand average speed fluctuation test 3.1.1 Subject to the provisions of the steady load conditions using a test speed of 150r/min, 250r/min, 500r/min, 750r/min, 1000r/min, 1100r/min, 1200r/min, 1500r/min, respectively, at full load and empty load conditions, be not less than 1min test. Uniform conditions for each sample, the sampling time is less than 1s, the measurement data is not less than 20. 3.1.2 Average speed fluctuation rate φ1 according to formula (1). φ1 = Like max (or like min) - like m Like m × 100 (1) Where. φ1 --- average speed fluctuation rate, the unit as a percentage (%); Maximum speed max --- like during the measurement, in revolutions per minute (r/min); Min --- like minimum speed during the measurement, in revolutions per minute (r/min); The average speed m --- like during the measurement, in revolutions per minute (r/min); Like m = 1 m1 Σ M1 --- times the speed recorded during a measurement period, m1 ≥20; 3.1.3 speed fluctuation value Δ shape 1 according to equation (2). Δ = 1 state like max (or like min) - like m (2) Where. Δ 1 --- like average speed fluctuation value, in revolutions per minute (r/min). 3.2 pump test bench cycle load speed fluctuation test 3.2.1 using JB/T 9734 provisions to keep a pump cylinder work load (the rest of the cylinder high-pressure oil bypass), respectively, in 300r/min, 500r/min, 750r/min, 900r/min, 1000r/min, 1200r/min, 1500r/min conditions, were measured at the roundabout drive shaft
