Description
Technical field
The invention belongs to mining hydraulic field of motors, particularly relate to a kind of equal distribution angle hydraulic cylinder type motor with linear filter, be mainly used in the power input on the coal winning machine of colliery face, flight conveyer, traction locomotive and crane etc.
Background technique
Coal industry is the pillar industry of China, and the safety in coal mining is again the most important thing.Because underground coal mine often can exist gas, 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 general also containing hydrogen sulfide, carbon dioxide, nitrogen and aqueous vapor, and the inert gas of trace, as helium and argon etc.At standard conditions, methane exists to butane with gaseous state, more than pentane is liquid.As naked light, i.e., there is " gas " blast, directly threaten the life safety of 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, and become the key factor of a restriction colliery development, the efficiency of coal mine equipment directly affects the manufacturing efficiency of mine.Therefore the coal mine equipment developing efficient quick safety is a vital task of China's coal-mine industrial construction.
