This paper introduces the service performances of MG—300W coal winning machine, analyses its forces and the existing problems in use, probes the easy damage of traveling wheels in the machine, and then completes the improvement of the traveling unit.

The operating conditions of applying EGSB reactor to treat the pentachlorophenol (PCP) wastewater and the degradation pathway of PCP were studied.

This paper investigate the effect of the different operating conditions on the aerobic sludge granulation and biological P removal characteristics in SBR by using synthetic domestic wastewater as feed.

It established a single fuel cell 3D model with serpentine flow field,computed the dynamic performance of PEM fuel cell engine,and concluded the best operating conditions which affect the dynamic performance of PEM fuel cell engine.

Progress of pollutants removal efficiency and the influence of operation conditions in membrane bioreactor;

The running condition of electrolytic system loaded with different amount of electricity when adopting peak-bottom charge running way are discussed as well as its approriate measures and economic effects.

Influence of operation condition on properties of ion-exchange membrane;

The paper introduces the insulation structures of open calcium carbide furnaces andanalyzes the operation conditions of insulation materials' It also discusses the design of insulationsytem and puts forward three methods for insulation examination.

On this basis,the performance of desulfurizing slurry-circling pump was researched on,which includes the influence of hydraulic designment of volute and balde,the medium characteristic and operation condition on the performance of pumps,and then the transformation proposal based on single-phase pump was proposed for the transportation of solid-liquid two-phase medium.
