Technical field
The utility model belongs to hydraulic motor technical field, specifically a kind of valve type flow radial plunger emulsion motor.
Background technique
Currently, in the hydraulic device that underground coal mine exploitation engineering uses, mostly using mineral oil as work and lubricant medium,
But mineral oil can pollute mine water since pollution is big, violate environmental protection concept, and mineral oil has flammable properties, safety
Difference, to underground mining work, there are very big security threats.Therefore, the use of mineral oil is both unsatisfactory for safe and efficient exploitation requirement,
Lasting exploit theory is not met again.Based on this, underground coal mine exploits hydraulic device used and mineral oil medium is changed to emulsification at present
Liquid, since emulsion is compared with mineral oil, viscosity is small, mobility is strong, the axis flow and valve plate distribution that conventional hydraulic motors use
Mode is not suitable for emulsion since leakage rate is big, and emulsion cannot play preferable lubrication effect due to poor lubricity
Fruit, required mineral oil mass is far smaller than the whole amount for being all mineral oil of tradition in lubricating function, so still using mineral oil
Make lubricant medium, it is necessary to a kind of hydraulic motor of novel flow mode.
