1.检查压力控制阀的工作压力或设定压力 在对泵进行测试之前，需要先检查并确保压力控制阀门的初始设定压力为该值该设定压力越高，泵的输出压力就越大压力控制阀的操作压力取决于流体本身以及所要输送的液体密度和速度、泵的额定输出压力以及其他因素。
例如，如果压力控制阀有三个出口时（在压力较低或压力较高时),请检查是否安装了压力调节阀如果没有压力控制阀且该压力不能达到设定值，请检查流量控制器是否已关闭以确定油腔是否泄漏在测试过程中，必须始终保持设定流量控制阀开启并保持一定时间，这将导致油腔内有足够压力来容纳液体并且不会发生泄漏。
2.检查压力阀是否打开 压力阀是液压泵中使用最多的阀门如果有一个压力调节阀，应将其打开并重新安装在泵上当流体压力控制阀关闭时，流体压力控制阀压力变化将导致泵不受控制流量如果流量明显变大而且流量也变大但流体压力控制阀不受控制流量，则说明液压泵没有达到设计要求。
如果这些压力变化导致流体压力控制阀不受控制流量变大，这表明液压泵必须重新安装需要进行检查 3.检查液压系统 当泵开始工作时，液压泵必须立即停止运行关闭液压阀以保持压力均衡检查液力变矩器是否被损坏或卡住关闭液压阀、阀芯和齿轮。
检查压力表是否正常，压力调节阀是否正常运行检查液压油泄漏值和泄漏类型（泄漏值）检查液压泵是否处于工作状态油压计应在泵中固定和稳定位置；避免运动部件或传感器损坏 90-R-100-HS-1-NN-80-S-4-T2-F-02-GBA-14-29-24 90R100HS1NN80S4T2F02GBA142924 90-R-100-HS-2-AB-60-P-3-S1-E-03-GBA-35-35-24 90R100HS2AB60P3S1E03GBA353524 90-R-100-HS-2-AB-60-P-3-S1-E-03-GBA-38-38-24 90R100HS2AB60P3S1E03GBA383824 90-R-100-HS-2-BC-60-P-4-S1-F-03-GBA-14-26-24 90R100HS2BC60P4S1F03GBA142624 90R100-HS-2-BC-80-S-3-S1-E-03-GBA-42-42-24 90R100HS2BC80S3S1E03GBA424224 90-R-100-HS-2-BC-80-S-3-S1-E-03-GBA-42-42-24 90R100HS2BC80S3S1E03GBA424224 90-R-100-HS-2-CD-60-P-3-F1-E-03-GBA-35-35-24 90R100HS2CD60P3F1E03GBA353524 90-R-100-HS-2-CD-60-P-3-F1-E-03-GBA-38-38-24 90R100HS2CD60P3F1E03GBA383824 90-R-100-HS-2-CD-60-P-4-F1-F-03-GBA-14-26-24 90R100HS2CD60P4F1F03GBA142624 90-R-100-HS-2-CD-80-P-3-C7-E-03-GBA-42-42-24 90R100HS2CD80P3C7E03GBA424224 90-R-100-HS-2-CD-80-P-3-S1-E-03-GBA-42-42-24 90R100HS2CD80P3S1E03GBA424224 90-R-100-HS-5-BC-60-S-4-S1-F-03-GBA-23-23-24 90R100HS5BC60S4S1F03GBA232324 90-R-100-HS-5-BC-60-S-4-S1-F-03-GBA-23-23-28 90R100HS5BC60S4S1F03GBA232328 90R100-HS-5-BC-80-S-4-C7-E-03-GBA-35-35-24 90R100HS5BC80S4C7E03GBA353524 90-R-100-HS-5-BC-80-S-4-C7-E-03-GBA-35-35-24 90R100HS5BC80S4C7E03GBA353524 90-R-100-HS-5-CD-60-L-3-F1-E-03-GBA-38-38-24 90R100HS5CD60L3F1E03GBA383824 90-R-100-HS-5-CD-60-L-3-S1-E-03-GBA-38-38-24 90R100HS5CD60L3S1E03GBA383824 90-R-100-HS-5-CD-60-S-3-F1-E-03-GBA-26-26-24 90R100HS5CD60S3F1E03GBA262624 90R100-HS-5-NN-60-L-4-C7-D-03-GBA-20-20-24 90R100HS5NN60L4C7D03GBA202024 90-R-100-HS-5-NN-60-L-4-C7-D-03-GBA-20-20-24 90R100HS5NN60L4C7D03GBA202024 90R100-HS-5-NN-80-R-3-C7-E-03-GBA-26-26-24 90R100HS5NN80R3C7E03GBA262624 90-R-100-HS-5-NN-80-R-3-C7-E-03-GBA-26-26-24 90R100HS5NN80R3C7E03GBA262624 90R100-HS-5-NN-80-R-3-C7-F-03-GBA-35-35-24-G005 90R100HS5NN80R3C7F03GBA353524G005 90-R-100-HS-5-NN-80-R-3-C7-F-03-GBA-35-35-24-G005 90R100HS5NN80R3C7F03GBA353524G005 90R100-HS-5-NN-80-R-3-F1-F-00-GBA-29-29-24 90R100HS5NN80R3F1F00GBA292924 90-R-100-HS-5-NN-80-R-3-F1-F-00-GBA-29-29-24 90R100HS5NN80R3F1F00GBA292924 90R100-HS-5-NN-80-S-4-C7-D-05-GBA-38-38-24 90R100HS5NN80S4C7D05GBA383824 90-R-100-HS-5-NN-80-S-4-C7-D-05-GBA-38-38-24 90R100HS5NN80S4C7D05GBA383824 90R100-HS-5-NN-80-S-4-C7-E-05-GBA-38-38-24 90R100HS5NN80S4C7E05GBA383824 90-R-100-HS-5-NN-80-S-4-C7-E-05-GBA-38-38-24 90R100HS5NN80S4C7E05GBA383824。
