Structure design of electric-hydraulic two-wayopen differential air door;

The automatic air door in trackless main haulage roadway designed by taking PLC as control core and using the optical-mechanical-electrical technology can solve the automatic control problems of underground traffic and air resistance.

According to air door of flameproof fan work situation and its structure,a 3-D calculated model of air door is established with finite element analysis.

Qianling coal mine according to the mine shaft air throttle chain-like use and the scene actual situation,transformed the mine shaft air throttle chain-like.

One incubator normally opened the air throttle on the fifth day,another opened the air throttle on the tenth day.

Proposals on damper layout for air and gas system of tw o 660 MW supercritical pressure boilers in Taishan Power Plant;

In recent two years, serious slagging has been found in Unit 4 boiler of Shaoguan Power Plant, which is deemed to be caused by the irrationality in the structure of double volute type turbulent burners, disposition of secondary air piping and dampers, layout of refractory belt, air distribution, etc.

The winding form of steel rope and the design of weel curve on frictional wheel mechanism to au-romaticly control air valve is introduced.

This had much to do with the moral standing of the family.
