In modern drilling machines for the drive of rotary-feeding mechanisms are increasingly common volumetric hydraulic drives.
The drill feed drive consists of an electric motor, a variable displacement pump, a hydraulic line including a safety valve and a throttle regulator, a hydraulic motor and a mechanical transmission from the hydraulic motor to the drilling tool, which is also acted upon by the rotator drive.
Математические модели привода вращательно-подающих механизмов (ВПМ) станков шарошечного бурения, необходимые для выбора эксплуатационных режимов управления процессами бурения и проектирования систем автоматического регулирования его параметров, изучены слабо ...
Studies of radial hydraulic turbine engines in the mine water network show that the characteristic of the network p *p(Q), reduced to the inlet of the turbine engine, is approximated closely enough by a quadratic parabola of the form ...
In practice of operation of hydraulic drive systems of mining machines a great role is played by hydraulic shocks arising at switching of its switchgear and often being the cause of failure of elements of hydraulic systems ...
