1故障现象混凝土输送泵的2个混凝土输送缸各由1个主液压缸驱动。2个主液压缸分为有杆腔连通(用于高压小排量)和无杆腔连通(用于低压大排量)2种连接方式,如附图所示。由于2个主液压缸有杆腔或无杆腔串接在一起,在正常情况下,其运行速度应该是协调一致的。但在实际使用过程中,有时会出现2个主液
1 Symptom Concrete pump two concrete delivery cylinder driven by a master cylinder. The two main hydraulic cylinders are divided into two ways of connecting rod chamber (for high pressure and small displacement) and rodless chamber (for low pressure and large displacement), as shown in the attached drawings. As the two main cylinder rod or rodless chamber connected in series, under normal circumstances, its operating speed should be coordinated. But in the actual use of the process, sometimes there will be two main liquid
