液壓泵站系統(tǒng)油缸轉(zhuǎn)向故障分析與排除方法

液壓站采用液壓轉(zhuǎn)向，不但結(jié)構(gòu)簡單，還有利于轉(zhuǎn)向液壓系統(tǒng)操作和維護，大大提高了液壓機器的可操縱性和駕駛舒適性。然而，在液壓油從油缸到工作元件的過程中，任何環(huán)節(jié)出現(xiàn)問題，對分析、排除轉(zhuǎn)向故障，制定對策非常重要。下面跟大家談下液壓泵站的一些故障和排除方法。

1、液壓油泵

首先要保證給液壓油泵足夠的輸入動力，定期檢查油泵固定是否牢固可靠，皮帶張緊力是否合適，及時觀察液壓泵的輸出壓力。如果液壓泵輸出壓力突然下降，應停車檢查，以免因泵卡死或磨損燒蝕而造成更大的損失。泵的齒頂與殼體內(nèi)孔配合間隙爲0.05~0.1mm，軸向間隙爲0.03~0.05mm。

2、液壓油缸

油缸內(nèi)的液壓油應加注至規(guī)定高度，同時油缸閥門開度應足夠大，以避免供油不足。液壓油型號應按規(guī)定加注，不能不同型號液壓油混加，以免引起油品變質(zhì)，使抗泡性、粘度、流動性能下降，液壓油缸要保持高度清潔，定期清洗過濾網(wǎng)，以避免吸油阻力過大，加劇泵和液壓油缸的磨損。

3、轉(zhuǎn)向液壓缸

油缸出現(xiàn)問題的現(xiàn)象肉眼能看到漏油，或機器在不平的路上行走時，前輪會自動的“到處亂跑”。其主要原因就是油缸內(nèi)活塞上的油封漏油。此時，應按照産品型號換上合格的油封，并確保裝配時高度清潔，同時保證活塞上的兩個油封唇口都向外，問題即可解決。當轉(zhuǎn)向機構(gòu)出現(xiàn)故障時，然后根據(jù)各部件的維修標準，進行認真細緻的維修，一般都能解決問題。
