Abstract
The utility model relates to a hydraulic-driving lubrication pump, which belongs to the technical field of lubrication equipment. The hydraulic-driving lubrication pump comprises a hydraulic motor, a hydraulic-driving pump, a solenoid directional valve and an oil pressing plate assembly arranged in an oil drum, wherein the hydraulic motor is connected via a crank mechanism to drive a piston in a hydraulic-driving pump oil tank to move; the hydraulic-driving pump oil tank is connected with an oil pressing plate assembly; and the oil outlet of the oil cylinder is provided with the solenoid directional valve to control the hydraulic-driving pump. The hydraulic-driving lubrication system disclosed by the utility model is mainly used for the centralized lubrication system of heavy machinery, such as mining machinery and construction industry. The hydraulic-driving lubrication system and a progressive distributor can form a progressive lubrication system. The hydraulic-driving lubrication system and a control element also can form a single-line damping lubrication system. Lubricating grease can be quantificationally conveyed to each lubricating point by a program controller in fixed time.
Description
Technical field
The utility model relates to a kind of hydraulic driving lubricant pump, belongs to the lubricating utensil technical field.
Background technique
At present domestic to be used for heavy machineries such as mining machinery, building industry are lubricated mainly be following several kinds of modes: the air-operated lubricating pump system of electronic lubricant pump, import and hydrodynamic lubrication pump etc.Pneumatic, the hydrodynamic lubrication pump series of producing like the LINCOLN company of the U.S. etc. are because the hydrodynamic lubrication pump is in design with the scale property and the particularity of producing, the domestic specialized factory that does not also produce the hydrodynamic lubrication pumping system at present.So exploitation and production hydrodynamic lubrication pump series broad market prospect.The difficult problem that the exploitation of this project will solve is the selection of fluid motor; Its performance must be applicable to different hydraulic environments; These research and development play positive impetus for the development of lubricated industry, for the occasion broad market prospect of utilization hydraulic oil such as mining machinery, building industry.
The problem of the current existence of hydrodynamic lubrication pump is the fluid motor unstable properties; Directly have influence on the lubrication effect of engineering goods such as mining machinery, building industry; The exploitation of this project will be studied the characteristic of different types of fluid motor under different operating modes exactly, selects a kind of motor that is suitable for operating conditions.
Summary of the invention
The utility model technical problem to be solved is: propose a kind of hydraulic driving lubricant pump, simple in structure, reliability is high, can be applicable to different work condition environments.
In order to solve above technical problem; Hydraulic driving lubricant pump provided by the invention; Comprise oil hydraulic motor, the pump that surges, solenoid directional control valve and be located at the pressure food tray assembly in the oil drum; Said oil hydraulic motor is through the moving in-oil cylinder piston motion of the said pump that surges of crank mechanism connecting band, and the oil cylinder of the said pump that surges links to each other with said pressure food tray assembly; Said oil cylinder oil outlet is installed said solenoid directional control valve and is controlled the pump that surges; Piston is stroke fuel feeding all up and down in the course of the work, and fuel delivery is directly proportional with the input quantity of hydraulic oil.
The technological scheme that the utility model further limits is: aforesaid hydraulic driving lubricant pump, said surging pumped oil port unloading valve also is installed, in order to the charge oil pressure of control grease.
Further, aforesaid hydraulic driving lubricant pump, the pressure food tray in the said pressure food tray assembly adopts lip seal configuration, guarantees that the use of pump is reliable and stable.
The beneficial effect of the utility model: the utility model can break away from the power that power supply relies on to be provided from engineering machinery or fluid-power motor under bad working environments, thereby has improved security of products and reliability.The utility model also has the following advantages in addition: (1) has adopted piston to drive the piston rod oiling, and accurate oil filling amount is provided; (2) oil hydraulic motor partly adopts linkage mechanism to drive slide block and realizes automatic reverse, and no control valve is reliable and stable; (3) press food tray to adopt lip seal configuration, guarantee function of use.

Embodiment
Embodiment one
Present embodiment is a kind of hydraulic driving lubricant pump, and structure is as depicted in figs. 1 and 2, comprises oil hydraulic motor 1, the pump 2 that surges, solenoid directional control valve 3 and be located at the pressure food tray assembly 5 in the oil drum 4, presses the pressure food tray in the food tray assembly 5 to adopt lip seal configuration; Oil hydraulic motor 1 is through the moving pump 2 in-oil cylinder piston motions of crank mechanism connecting band hydrodynamic, and the oil cylinder of the pump 2 that surges links to each other with pressing food tray assembly 5; The oil cylinder oil outlet is installed the solenoid directional control valve 3 controls pump continuous oil supply that surges, and pumps oil port unloading valve 6 also is installed surging, and oil drum is provided with and the liquid level display module 7 of pressing the food tray assembly to link to each other.
The pressure of hydraulic motor controlled hydraulic oil and flow in the present embodiment; Solenoid directional control valve is controlled the unlatching of the pump that surges; Pump is realized automatic running by controller and pressure switch, stroke fuel feeding all up and down in the working procedure, and fuel delivery is directly proportional with the input quantity of hydraulic oil; Surge pump by fluid motor-driven, and oil hydraulic motor connects the in-oil cylinder piston of drive through crank mechanism and does knee-action, and through oil cylinder one-way valve effect up and down, grease is exported; When the motor revolution moving once, crank then knee-action once, in the knee-action process, it is fuel-displaced that pump all keeps, and oil pump capacity is 1/2 of each circulation discharge capacity.
The utility model can also have other mode of execution, and the technological scheme that equal replacement of all employings or equivalent transformation form all drops within the scope of the utility model requirement protection.
