?1.檢查壓力控制閥的工作壓力或設(shè)定壓力 在對(duì)泵進(jìn)行測(cè)試之前，需要先檢查并確保壓力控制閥門的初始設(shè)定壓力為該值該設(shè)定壓力越高，泵的輸出壓力就越大壓力控制閥的操作壓力取決于流體本身以及所要輸送的液體密度和速度、泵的額定輸出壓力以及其他因素。
例如，如果壓力控制閥有三個(gè)出口時(shí)（在壓力較低或壓力較高時(shí)),請(qǐng)檢查是否安裝了壓力調(diào)節(jié)閥如果沒有壓力控制閥且該壓力不能達(dá)到設(shè)定值，請(qǐng)檢查流量控制器是否已關(guān)閉以確定油腔是否泄漏在測(cè)試過程中，必須始終保持設(shè)定流量控制閥開啟并保持一定時(shí)間，這將導(dǎo)致油腔內(nèi)有足夠壓力來容納液體并且不會(huì)發(fā)生泄漏。
2.檢查壓力閥是否打開 壓力閥是液壓泵中使用最多的閥門如果有一個(gè)壓力調(diào)節(jié)閥，應(yīng)將其打開并重新安裝在泵上當(dāng)流體壓力控制閥關(guān)閉時(shí)，流體壓力控制閥壓力變化將導(dǎo)致泵不受控制流量如果流量明顯變大而且流量也變大但流體壓力控制閥不受控制流量，則說明液壓泵沒有達(dá)到設(shè)計(jì)要求。
如果這些壓力變化導(dǎo)致流體壓力控制閥不受控制流量變大，這表明液壓泵必須重新安裝需要進(jìn)行檢查 3.檢查液壓系統(tǒng) 當(dāng)泵開始工作時(shí)，液壓泵必須立即停止運(yùn)行關(guān)閉液壓閥以保持壓力均衡檢查液力變矩器是否被損壞或卡住關(guān)閉液壓閥、閥芯和齒輪。
檢查壓力表是否正常，壓力調(diào)節(jié)閥是否正常運(yùn)行檢查液壓油泄漏值和泄漏類型（泄漏值）檢查液壓泵是否處于工作狀態(tài)油壓計(jì)應(yīng)在泵中固定和穩(wěn)定位置；避免運(yùn)動(dòng)部件或傳感器損壞 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。
