rexroth油泵為什么打不起壓，如何解決力士樂Rexroth油泵壓力變小的原因

力士樂REXROTH柱塞泵液壓系統(tǒng)壓力打不起來的原因和相應的解決方法：

(一)產生原因

1.塑料注射成型機液壓系統(tǒng)中的電磁閥動作失靈。

2.液壓泵（液壓葉片泵、液壓齒輪泵、液壓柱塞泵）站中的大活塞或活塞環(huán)損壞翻油。

3.液壓泵站中的行程閥的閥芯與閥體配合間隙過大，高壓時大盆漏油。

4. 液壓站中的壓力繼電器動作失靈。

5.液壓系統(tǒng)中的充液油缸的活塞卡死不動。

6.液壓系統(tǒng)(也稱作液壓動力單元、小型液壓系統(tǒng)、微型液壓泵站、液壓站等，)中的液壓油泵內部件磨損。

7.液壓泵站中充液油缸的活塞炸裂。

8.空氣進人了液壓站中的充液油缸。

(二)解決方法

1.拆下修理或更換液壓系統(tǒng)中的電磁閥。

2.檢修或更換液壓泵站中的活塞環(huán)。

3.更換液壓泵站中的符合性能要求的行程閥。

4.拆下檢修或更換液壓站中的順序閥。

5.拆下修復或更換液壓系統(tǒng)中的充液油缸的活塞。
