Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
It elaborates combined with specific embodiments below to the utility model, the present embodiment is with technical solutions of the utility model
Premised on, the detailed implementation method and specific operation process are given.
As shown, the utility model is a kind of plunger pump, including oil storage barrel 1 and the pump oil machine being arranged in oil storage barrel 1
Structure, oil storage barrel 1 are provided with for fuel-displaced overflow valve 2 outside, and the pump oil mechanism includes two be symmetricly set in oil storage barrel 1
Limit plate 3 forms sliding rail between two limit plates 3, and sliding is arranged dynamic frame 4 in sliding rail, in the power frame 4
It is provided with the eccentric wheel 5 to match with its width, the eccentric wheel 5 passes through the driving of power-equipment 6 being arranged in outside oil storage barrel 1 and turns
Dynamic to drive power frame 4 to reciprocatingly slide along sliding rail, power frame 4 is provided with pump oil plunger 7 along the two sides of glide direction, pump
Fuel feed hole 8 is provided on 7 side wall of oil piston, pump oil plunger 7, which exports, to be connected with the check valve 9 being arranged on 1 side wall of oil storage barrel
It connects, the outlet of check valve 9 is connect by pipeline 10 with overflow valve 2.
The above are the basic embodiments of the utility model, can be improved further, optimize or limit on the basis of above
It is fixed.
Further, the drain mast 11 connecting with oil storage barrel 1 is provided on the overflow valve 2.
Further, the power-equipment 6 is motor and speed reducer group.
Further, the pump oil plunger 7 includes piston cylinder 701 and the piston rod being slidably arranged in piston cylinder 701
702, spring 703 is arranged on the body of rod that the piston rod 702 is located at outside piston cylinder 701, and 702 free end of piston rod sticks on
The setting of 4 side wall of power frame.
The working principle of the utility model is as follows:
Power-equipment 6 reciprocatingly slides in sliding rail with 5 eccentric motion of movable eccentric wheel, propulsion power frame 4, power frame 4
It turns left and pushes the side compression to the left of piston rod 702 in left side when sliding, power frame 4, which is turned right, pushes the piston rod 702 on right side when sliding
Side compression to the right；
When 702 compression movement to the right of piston rod, the fuel feed hole 8 on the pump oil plunger 7 in left side can be in the work of pressure
Under " oil pumping ", oil enters the inner cavity of piston cylinder 701 by the fuel feed hole 8 in left side；
When 702 compression movement to the left of piston rod, fuel feed hole 8 is sealed, forms sealing state in piston cylinder 701 at this time,
The oil pressure of 701 inner cavity of piston cylinder is sent to check valve 9, and 9 inner cavity of check valve is entered further by check valve 9, and it is single
The combination that steel ball, baffle ring and spring are used to valve forms a dual one-way valve, guarantees that the oil of 9 inner cavity of check valve no longer flows back.
Pump oil plunger 7 is connected through a screw thread or other connection types are installed on the valve body of check valve, and valve body is attended class installation
One or more pump oil plungers 7, and valve body is bolted on the outside of oil storage barrel 1, pump oil plunger 7 when something goes wrong
It waits, it is only necessary to which the bolt for dismantling prepackage can take out pump oil plunger 7, and maintenance is convenient.
A kind of plunger pump described in the utility model, structure is simple, and failure rate is low and easy-maintaining, power frame as sliding block,
The movement of driving pump oil piston, will be separately positioned between power frame and pump oil plunger, is not set to integral structure, once there is event
Barrier, can directly extract pump oil piston out, replacement and repair easy to disassemble after check valve is removed from oil storage barrel.
In use, multiple groups pump oil piston can also be arranged in the two sides of power frame in oil storage barrel, pass through the sliding of power frame
It realizes the co-operation of multiple groups pump oil piston, improves pump oil efficiency.
When not needing pump oil, the oil stored in overflow valve can be flowed back by drain mast and be sent into oil storage barrel.
