Description
Technical field
The utility model belongs to mechanical equipment technical field, relates in particular to a kind of hydraulic booster pump.
Background technology
At present, booster pump adopts pressurized cylinder structure more, and reversing arrangement is external, in the time that piston moves to oil cylinder end face extreme position, and reversal valve commutation, the oil inlet and oil return mouth of pressurized cylinder commutates, thereby realizes the function of booster pump continuous operations. Its reversing mode is divided into again manual reverse of direction and automatic reverse. Manual reverse of direction booster pump, for the hydraulic test of a large amount of high-pressure oil of needs, needs operating personnel's frequent operation reversal valve commutation, use inconvenient, and pressure and flowed fluctuation large. Automatic reverse booster pump, arranges sensor in oil cylinder end and sends signal, controls outside electromagnetic switch valve events, and still, its complex structure, volume are larger, with high costs, and solenoid directional control valve is not suitable for using at the environment that is having requirement of explosion proof.
Summary of the invention
The purpose of this utility model is that design one can realize the hydraulic booster pump that super-pressure (>=50MPa) pressure oil is supplied with continuously. realizing the technical scheme that the purpose of this utility model takes is: a kind of hydraulic booster pump, includes fuel tank cap, motor flange, hydraulic motor, choke valve, shaft coupling, air filter, delivery valve, reversing control valve, fuel tank, high pressure valve body, volute spring, plunger, drive guide post and camshaft, it is characterized in that: the hydraulic motor that oil-in is provided with choke valve is fixed on motor flange, motor flange and eccentric shaft are installed weld assembly and are screwed in fuel tank cap, all, with seam location, ensure hydraulic motor, motor flange, eccentric shaft is installed weld assembly, bearing (ball) cover is coaxial, connects stock by guide post, high pressure valve body, plunger and volute spring link together, and hydraulic motor is connected with shaft coupling with camshaft, camshaft, volute spring, guide post and plunger move back and forth in high pressure valve body, oil sucting valve, overflow valve, delivery valve is connected on high pressure valve body, and reversing control valve is fixed in fuel tank cap, and delivery valve inserts in reversing control valve.
The utility model can be realized the continuous supply of super-pressure (>=50MPa) pressure oil; Rational in infrastructure, Hydraulic Elements completely, flow is adjustable continuously, adjustable range is large, does not need signal of telecommunication control, does not also need external control reversal valve, can be widely used in various complex environments, owing to having got rid of electric dependence, install and use flexibility greatly to improve.

Detailed description of the invention
With reference to accompanying drawing, a kind of hydraulic booster pump, includes fuel tank cap 1, motor flange 2, hydraulic motor 3, choke valve 4, shaft coupling 5, air filter 6, delivery valve 7, reversing control valve 8, fuel tank 9, high pressure valve body 11, volute spring 14, plunger 15, drive guide post 16 and camshaft 18, it is characterized in that: the hydraulic motor 3 that oil-in is provided with choke valve 4 is fixed on motor flange 2, motor flange 2 and eccentric shaft are installed weld assembly 17 and are screwed in fuel tank cap 1, all, with seam location, ensure hydraulic motor 3, motor flange 2, eccentric shaft is installed weld assembly 17, bearing (ball) cover 19 is coaxial, connects stock 13 by guide post 16, high pressure valve body 11, plunger 15 and volute spring 14 link together, and hydraulic motor 3 is connected with camshaft 18 use shaft couplings 5, camshaft 18, volute spring 14, guide post 16 and plunger 15 move back and forth in high pressure valve body 11, oil sucting valve 12, overflow valve 10, delivery valve 7 is connected on high pressure valve body 11, and reversing control valve 8 is fixed in fuel tank cap 1, and delivery valve 7 inserts in reversing control valve 8.
The course of work of the present utility model is: low-pressure hydraulic oil drives the axle of hydraulic motor 3 to rotate, and drives camshaft 18 to rotate by shaft coupling 5. Volute spring 14 is pressed in plunger 15 on guide post 16, thereby guide post 16 is pressed on the eccentric wheel of camshaft 18 always. Camshaft 18 rotates, and eccentric wheel promotes plunger 15 by guide post 16, and under the acting in conjunction of camshaft 18 and volute spring 14, plunger 15 is in the interior reciprocating motion of high pressure valve body 11. When plunger 15 moves to pull-out high pressure valve body 11 directions, delivery valve 7 cuts out, and oil sucting valve 12 is opened from the interior oil suction of fuel tank 9; Plunger 15 is to being pressed into 11 directions whens motion of high pressure valve body, and oil sucting valve 12 is closed, and pressure oil enters in reversing control valve 8 through delivery valve 7. Can switch the fuel-displaced and oil return of reversing control valve 8 by handle, the oil return of reversing control valve 8 can be passed through the direct oil return case 9 of its base apertures. Set booster pump output pressure (more than can reaching 50MPa) by overflow valve 10, can regulate low pressure oil-feed flow by hydraulic motor 3 oil-in place choke valves 4, thereby reach governor motor rotating speed, and then reach the fuel-displaced oil mass of adjusting high pressure.
