Abstract
The utility model discloses a binocular is filtered coal and is ground change loading hydraulic system immediately, oil tank traditional chinese clothing double pump, a pump in the double pump is connected with the grinding roller hydraulic cylinder's of mechanism the pole chamber that has through a oil pipeline, and another pump in the double pump is connected with the grinding roller hydraulic cylinder's of mechanism no pole chamber through the 2nd oil pipeline, set up first, the automatically controlled proportion overflow valve of second respectively on a oil pipeline, the 2nd oil pipeline, control oil transportation pressure, set up on a oil pipeline and be used for adjusting that the grinding roller rises, falling speed's one -way governing valve device, set gradually binocular filter, cooler on the oil pipe way returning of first, the automatically controlled proportion overflow valve of second. The utility model discloses it is rational in infrastructure, can conveniently realize the loading and adjust that work efficiency is high, the system is small, and operation maintenance is convenient.
Description
Technical field
The utility model relates to a kind of coal hydraulic system of vertical mill.
Background technique
Existing coal hydraulic system of vertical mill, does not have special loading adjusting device, and loading can not realize fine adjustment, affects service behaviour and effect.
Summary of the invention
It is rational in infrastructure that the purpose of this utility model is to provide one, conveniently can realize the bitubular filtration coal Vertical Mill change loading hydraulic system loading adjustment, use safety.
Technical solution of the present utility model is:
A kind of bitubular is filtered coal Vertical Mill and is become loading hydraulic system, it is characterized in that: comprise fuel tank, duplex pump is filled in fuel tank, a pump in duplex pump is connected with the rod chamber of grinding roller mechanism lifting hydraulic cylinder by the first oil transport pipeline, and another pump in duplex pump passes through the second oil transport pipeline and is connected with the rodless cavity of grinding roller mechanism lifting hydraulic cylinder; First oil transport pipeline, the second oil transport pipeline arrange first, second automatically controlled proportional pressure control valve respectively, controls fuel transfer pressure; First oil transport pipeline arranges the unidirectional control valve device for regulating grinding roller rising, rate of descent, the return line of first, second automatically controlled proportional pressure control valve sets gradually duplex filter, cooler, the return line of grinding roller mechanism lifting hydraulic cylinder arranges the relief valve of manual off-load operation; Described grinding roller mechanism lifting hydraulic cylinder has three lifting hydraulic cylinders in parallel, and three lifting hydraulic cylinders connect with corresponding unidirectional control valve device respectively; First oil transport pipeline arranges the relief valve communicated with the rod chamber of grinding roller mechanism lifting hydraulic cylinder, and this relief valve is connected with accumulator.
The utility model is rational in infrastructure, can conveniently realize loading regulating, and working efficiency is high, and system bulk is little, convenient operating maintenance; Adopt duplex filter, strainability is better; The relief valve that communicates with the rod chamber of grinding roller mechanism lifting hydraulic cylinder and accumulator is adopted to be connected, damping, safety.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
A kind of bitubular is filtered coal Vertical Mill and is become loading hydraulic system, comprise fuel tank 1, duplex pump is filled in fuel tank, a pump in duplex pump 2 is connected by the rod chamber of the first oil transport pipeline 3 with grinding roller mechanism lifting hydraulic cylinder 4, and another pump 5 in duplex pump passes through the second oil transport pipeline 6 and is connected with the rodless cavity of grinding roller mechanism lifting hydraulic cylinder 4; First oil transport pipeline, the second oil transport pipeline arrange first, second automatically controlled proportional pressure control valve 7,8 respectively, for controlling fuel transfer pressure; First oil transport pipeline arranges the unidirectional control valve device 9 for regulating grinding roller rising, rate of descent, the return line of first, second automatically controlled proportional pressure control valve sets gradually duplex filter 10, cooler 11, the return line of grinding roller mechanism lifting hydraulic cylinder arranges the relief valve 12 of manual off-load operation; Described grinding roller mechanism lifting hydraulic cylinder has three lifting hydraulic cylinders in parallel, and three lifting hydraulic cylinders connect with corresponding unidirectional control valve device respectively; First oil transport pipeline arranges the relief valve 13 communicated with the rod chamber of grinding roller mechanism lifting hydraulic cylinder, and this relief valve is connected with accumulator 14.
