热轧卷板厂中宽带2~#卷取机2~#、3~#助卷辊气改液

气动系统的缺点是,冬季由于气温影响动作慢,甚至是不动作。气改液主要是改善这一制约生产的要素,完善生产所需。通过系统的分析、计算,合理的选型,成功的实现了气改液的方案,实现了常规阀控制的液压系统的安全、可靠运行。

带钢生产线卷取机气动夹送辊液压改造

夹送辊气动系统故障多,压缩空气含水及杂质较多,北方冬季气温低,易造成气缸、气动阀犯卡,气动改为液压 消除气动系统弊端,提高设备稳定性。

Hydraulic Installation for Water Aeration

This paper presents some problems related to water quality and the condition of lakes in Romania, as well as methods for improving the quantity of oxygen dissolved in water. A method for water aeration and the installation used to implement it are described and the associated advantages regarding the reduction in the level of eutrophication are highlighted. The hydraulic installation for improving the quality of water from lakes, basins, reservoirs or slow flowing rivers was designed and tested in our hydraulics laboratory during a research project. It is floatable, environmentally friendly, and energetically autonomous, being powered by photovoltaic panels, which together with rechargeable batteries can assure a continuous operation. This installation could also be used in early stages of wastewater treatment. Experimental results regarding the performance curves of the hydraulic installation are also presented.
