如果气不畅，要及时进行处理； 1:柱塞泵在正常工作状态下，应将气缸内吸入的空气排尽不允许有空气进入但当柱塞泵运行到一定转速时，系统内的空气便可通过柱塞阀排出柱塞泵在运转中出现压力升高、排气排尽、活塞在压缩行程运动开始时的压力应控制在0.2Mpa以内，当压力高于0.2Mpa时可排气，而高于0.2Mpa时，则必须停机，再作检查：当压力为0.6~0.8Mpa时若仍有空气就应处理；2:为防止油中混入空气造成系统磨损及污染而导致燃烧不良；在活塞顶部或排气管堵塞时排气管出现气阻而造成气流量不足；柱塞泵产生卡滞及空转；柱塞泵吸不上空气；柱塞泵供油不足；压力过低后停止工作。
造成燃烧不完全和排气不畅的原因是柱塞泵和系统部件中有杂质或润滑油不足；或柱塞泵轴承润滑不良、进排气系统中堵塞；柱塞泵泵体内温度过高；柱塞泵缸体密封圈老化；柱塞泵泵油嘴堵塞或油量不足等因素造成漏油；活塞密封环变形或损坏等情况导致气泵供油不足；或吸力过大而引起转子不动等等；3:有一定的压力但不超过工作压力。
原因：进空气过多或排不上空气；进空气量过小；进气门打开后排不出废气而导致柱塞泵不工作；或者是启动中发动机怠速运转了几分钟后突然停机；造成气缸内压力上升速度过快或过慢；发动机中排出废气太多；活塞在下止点时活塞在上止点处停顿不动；活塞与连杆中间空隙过大；气缸上垫圈损坏等因素造成活塞向下运动或缸体上部活塞向下运动时排气不畅；进排气通道堵塞使压缩空气不能及时排出从而导致排气不畅。
柱塞泵在运转过程中排气可能引起故障并引起烧机油、烧坏发动机也有可能是在发动机怠速运转时突然停止排气时而造成发动机温度过高 90R130-KA-1-CD-80-L-3-F1-F-03-EBA-35-35-20 90R130KA1CD80L3F1F03EBA353520 90-R-130-KA-1-CD-80-L-3-F1-F-03-EBA-35-35-20 90R130KA1CD80L3F1F03EBA353520 90R130-KA-1-CD-80-L-4-F1-F-03-GBA-40-40-24 90R130KA1CD80L4F1F03GBA404024 90-R-130-KA-1-CD-80-P-3-C8-F-03-GBA-20-20-24 90R130KA1CD80P3C8F03GBA202024 90-R-130-KA-1-CD-80-P-3-C8-H-03-GBA-35-35-24 90R130KA1CD80P3C8H03GBA353524 90-R-130-KA-1-CD-80-P-4-F1-H-03-GBA-32-32-24-F001 90R130KA1CD80P4F1H03GBA323224F001 90-R-130-KA-1-CD-80-P-4-F1-H-03-GBA-35-35-24 90R130KA1CD80P4F1H03GBA353524 90R130-KA-1-CD-80-R-3-F1-H-03-GBA-35-35-24 90R130KA1CD80R3F1H03GBA353524 90-R-130-KA-1-CD-80-R-3-F1-H-03-GBA-35-35-24 90R130KA1CD80R3F1H03GBA353524 90R130-KA-1-CD-80-R-4-C8-H-03-EBA-38-38-26 90R130KA1CD80R4C8H03EBA383826 90-R-130-KA-1-CD-80-R-4-C8-H-03-EBA-38-38-26 90R130KA1CD80R4C8H03EBA383826 90-R-130-KA-1-CD-80-R-4-F1-F-03-GBA-35-35-24 90R130KA1CD80R4F1F03GBA353524 90-R-130-KA-1-CD-80-S-3-C8-F-03-GBA-42-42-30 90R130KA1CD80S3C8F03GBA424230 90R130-KA-1-CD-80-S-3-C8-H-04-GBA-42-42-24 90R130KA1CD80S3C8H04GBA424224 90-R-130-KA-1-CD-80-S-3-C8-H-04-GBA-42-42-24 90R130KA1CD80S3C8H04GBA424224 90R130-KA-1-DE-80-L-3-C8-F-04-GBA-35-35-24 90R130KA1DE80L3C8F04GBA353524 90-R-130-KA-1-DE-80-L-3-C8-F-04-GBA-35-35-24 90R130KA1DE80L3C8F04GBA353524 90R130-KA-1-DE-80-L-4-F1-F-03-GBA-14-14-24 90R130KA1DE80L4F1F03GBA141424 90-R-130-KA-1-DE-80-L-4-F1-F-03-GBA-14-14-24 90R130KA1DE80L4F1F03GBA141424 90-R-130-KA-1-DE-80-P-3-C8-F-03-GBA-20-20-24 90R130KA1DE80P3C8F03GBA202024 90-R-130-KA-1-DE-80-P-3-C8-H-03-GBA-42-42-24 90R130KA1DE80P3C8H03GBA424224 90R130-KA-1-DE-80-R-3-C8-F-04-GBA-32-32-20 90R130KA1DE80R3C8F04GBA323220 90-R-130-KA-1-DE-80-R-3-C8-F-04-GBA-32-32-20 90R130KA1DE80R3C8F04GBA323220 90-R-130-KA-1-DE-80-R-3-F1-F-03-GBA-38-38-24 90R130KA1DE80R3F1F03GBA383824 90R130-KA-1-DE-80-R-3-F1-H-09-GBA-38-38-24 90R130KA1DE80R3F1H09GBA383824 90-R-130-KA-1-DE-80-R-3-F1-H-09-GBA-38-38-24 90R130KA1DE80R3F1H09GBA383824 90R130-KA-1-NN-80-L-3-F1-F-00-GBA-17-17-20 90R130KA1NN80L3F1F00GBA171720 90-R-130-KA-1-NN-80-L-3-F1-F-00-GBA-17-17-20 90R130KA1NN80L3F1F00GBA171720 90R130-KA-1-NN-80-L-3-F1-F-00-GBA-23-23-28 90R130KA1NN80L3F1F00GBA232328 90-R-130-KA-1-NN-80-L-3-F1-F-00-GBA-23-23-28 90R130KA1NN80L3F1F00GBA232328 90-R-130-KA-1-NN-80-L-3-F1-F-03-GBA-23-23-24 90R130KA1NN80L3F1F03GBA232324 90-R-130-KA-5-NN-80-S-4-F1-H-03-GBA-35-35-24 90R130KA5NN80S4F1H03GBA353524。
