1、Calvin Wang 08-9-25,Product Introduction of Power Steering Pump,液压助力转向泵产品简介,Application in Vehicle,Application in Vehicle,Pump Function,Minimum output: 2.27 L/Min flow at 465 RPM against 4.585.07 MPa pressure低流量 2.27 L/Min (465 RPM, 4.585.07 MPa)，发动机怠速时提供一定的转向助力 Maximum output: 7.458.85 L/Min flow a

2、t 1500 RPM against 0.35 MPa pressure高流量 7.458.85 L/Min (1500 RPM, 0.35MPa)，发动机正常运转时提供恒定的转向助力 Relief pressure: 95105 MPa at 1500 RPM泄压值 95105 MPa (1500 RPM)，当方向盘打死或转到极限位置，保护HPS系统,Pump Function,Pump Function,Pump Function,Pump Function,Pump Structure,Pump Structure,Pump Structure,Pump Type,Pump Type,P

3、ump Type,Pump Type,Pumps Rapid Response,Minor modifications to pump components can vary displacement, high rpm flow rate, relief pressure, and mounting configuration 根据客户的要求(低流量、高流量、泄压值与安装位置等）Power Steering Pump团队能作出快速反应，并再原有产品基础尽量减少更改,Pumps DV/PV Test,注 ： DV (Design Validation) test for prototype s

4、ample 即手工样件设计验证 PV (Process Validation) test for OTS sample 即OTS样件验证,Durability test 耐久性测试 - To confirm deterioration after long operating 确认长时间运行之后功能下降或丧失 - Including sealing parts, springs, wear of sliding surface 包括密封件、弹簧、摩擦面 Special test for vital mode 关键实效模式测试 - To confirm what condition occur

5、vital failure 确认在什么情况下会发生关键的性能实效 - Seizure test, cold start test, high temp test, high pressure test, high belt load test, etc 卡死测试、冷启动测试、高温测试、高压测试、皮带轮受载测试等 Breakage test 破坏性试验 - To verify the safety factor on strength of each parts 验证零件在强度方面的安全性能,Pumps Localization,1. Localized: Housing, Pulley, Re

6、turn Tube, Pressure Plate, Thrust Plate 2. To be localized: End Cover, Drive Shaft, Standard-Flow Fitting, Valve 3. Plan to be localized: Ring, Rotor 4. Left: Spring Parts, Sealing Parts, Pin, Vane,Pumps Problem at Present,1. Leakage: You may find oil drop after parking and abnormal noise if too much leaking 泄漏（现有检测设备气密性测试） 2. Noisy: You catch abnormal noise when turn the wheel 噪音（现有检测设备STC噪音测试） 3. Heavy steeling: It is too hard to turn wheel and you
