Description

With emulsification liquid filter under ore deposit etc. angle of distribution hydraulic cylinder type motor

Technical field

The invention belongs to mining hydraulic field of motors, particularly relate to a kind of with emulsification liquid filter under ore deposit etc. angle of distribution hydraulic cylinder type motor, be mainly used in the power input on coal winning machine, flight conveyer, traction locomotive and the crane etc. of colliery face.

Background technique

Coal industry is the pillar industry of China, and the safety in coal mining is again the most important thing.Owing to often can there is gas under coal mine, the main component of gas is alkane, and wherein methane accounts for the overwhelming majority; separately there are a small amount of ethane, propane and butane; in addition generally also contain hydrogen sulfide, carbon dioxide, nitrogen and aqueous vapor, and the inert gas of trace, as helium and argon etc.Under the standard condition, methane to butane exists with gaseous state, and pentane is liquid above.As naked light, i.e., there is " gas " blast, the life safety that is directly threatening miner in incendivity.In order to reduce and prevent the generation of hair explosive accident, must be high to the requirement of underground work safety coefficient.

Along with the development of new and high technology and modern production, the output in colliery is also in rising from year to year, coal mine equipment also just seems even more important for the development in colliery, has become the key factor of a restriction colliery development, and the efficiency of coal mine equipment directly affects the manufacturing efficiency of mine.Therefore the coal mine equipment that develops efficient quick safety is a vital task of China's coal-mine industrial construction.
