Water inlet is provided on the pump case of water valve frame side, the water inlet connects water inlet vavle shelf, is arranged on the pump case of the water chamber
There is water outlet；Bent axle, connecting rod and plunger are provided in the crankcase, bent axle connects connecting rod, and connecting rod passes through plunger pin connecting pole
The top of plug, curved bar is stretched out outside shell；Existing plunger pump driving drives bent axle rotation by external power, and then drives piston plunger
It moves to realize the purpose of supercharging.
As notification number is that 104373317 A of CN disclose a kind of plunger pump, including pump case, the bent axle in pump case,
At least one end of direct driving motor, the bent axle is stretched out outside the pump case, and the straight drive electricity of the crankshaft end connection outside the pump case is being stretched out
Motor is directly connect by machine, this mode with bent axle, but this common inner rotor motor is directly connect with bent axle, is needed pair
The shape of existing crankcase and electric machine casing is transformed, and on the one hand to install electric machine casing when installation, while installing again
Rotor, and due to having suction before rotor and stator, installs inconvenient, while the motor of this structure is not
It can be organically combined into an entirety with crankcase.
Invention content
The purpose of the present invention is to provide a kind of electric direct-drive plunger pumps, and the end cap of motor is used as outer rotor,
Without being transformed to existing crankcase, crankshaft end cover need to only be opened, motor stator core is fixed on crankshaft end axis
In bearing, then motor outer rotor with it is axially mounted and fix from crankshaft end, the invention enables motors on plunger pump
Install it is very convenient, due to use outer rotor and end cap integral structure, structure carry out flattening design, make full use of space, knot
Structure closely, while the motor of same volume have bigger output power.
Following technical scheme is used to achieve the above object：
A kind of electric direct-drive plunger pump, including crankcase and the pump housing, the both sides of crankcase are provided with bearing block, crankshaft two end with
Bearing block coordinates, it is characterised in that：Direct drive type outer rotor motor, the direct-drive type are provided on the outside of the bearing block
External rotor electric machine includes end cap and is placed in the stator core of end cap inner annular, is installed on the outside of the bearing block several
Mounting hole has to open up on a cricoid stator core and sets the corresponding positioning through hole of mounting hole, outside stator core fixed bearing block
Side is simultaneously arranged with the coaxial bearing on bearing block；The end cap includes axial part and radial part, is arranged in the inner wall of axial part
There are magnetic links, the connector sleeve coordinated with crankshaft end is provided centrally on the inside of radial part.
The connector sleeve center offers the through-hole through radial part, is provided in the crankshaft end and coordinates with through-hole
Screw hole.
The structure of existing motor is improved appropriately in the present invention, eliminates conventional electric machine casing, bearing, shaft
And internal rotor, stator compressed is arranged, then rotor and end cap setting are integral, and when installation need to only open crankshaft end cover,
Motor stator core is fixed on crankshaft end bearing block, then motor outer rotor and and fixation axially mounted from crankshaft end
, installation is very convenient, the side of crankcase is close to after motor installation so that pump housing entirety center of gravity will not be deviated obviously, column
Plug pump normally keep flat and will not topple over, the globality of motor and crankcase and the pump housing closely, the present invention to the structure of motor into
Row flattening designs, make full use of the structure of existing crankcase, structure closely, motor ingenious in design, same volume tool
There is the output power of bigger.

Fig. 2 is the structural schematic diagram after present invention installation motor；
Fig. 3 is the decomposition texture schematic diagram of the present invention；
Fig. 4 is the structural schematic diagram of the outer rotor of the present invention.
Specific implementation mode
As shown in Figs 1-4, a kind of electric direct-drive plunger pump, including crankcase 1 and the pump housing 2, the both sides setting of crankcase 1
There are bearing block 11,12 both ends of bent axle to coordinate with bearing block 11, it is characterised in that：It is provided with directly in the outside of the bearing block 11
Drive formula external rotor electric machine 3, the direct drive type outer rotor motor 3 include end cap 31 and the stator iron for being placed in 31 inner annular of end cap
Core 32 is installed with several mounting holes 13 in 11 outside of bearing block, has to open up on a cricoid stator core 32 and set peace
The corresponding positioning through hole 33 in hole is filled, the outside of 32 fixed bearing block 11 of stator core is simultaneously set with the coaxial bearing on bearing block 11
It sets；The end cap 31 includes axial part 51 and radial part 52, the inner wall of axial part 51 is provided with magnetic links 53, in radial part
52 insides are provided centrally with the connector sleeve 55 coordinated with crankshaft end, and 55 center of connector sleeve is offered through radial part
Through-hole 56, be provided with the screw hole 16 coordinated with through-hole in 12 end of bent axle.
The present invention install when first pass through screw by cricoid stator core 32 be fixed on bearing block 11 outside and bearing it is same
Axis is arranged, then axial to push end cap 31 so that axial then by the connector sleeve 55 and 12 end alignment of bent axle of 31 inside of end cap
Periphery at the magnetic links 53 of 51 inside of portion with stator core 32 passes through through-hole that end cap 31 and bent axle 12 is tight finally by screw
Gu.
For end cap before being installed in place, magnet steel 53 has certain distance with stator core 32, not will produce when the present invention installs
It attracts each other, therefore assembles very convenient；Present invention eliminates conventional electric machine casing, bearing, shaft and internal rotor, and end cap
Integral structure is acted on outer rotor, is the case that rotor is again motor, closely, this structure makes the knot of motor to structure
Structure more flattening greatly simplifies the structure of motor, and the center of gravity of installation back-plunger pump does not have apparent offset, and normal place will not
There is inclination problem；The present invention is not necessarily to the structure of crankcase and the pump housing without redesigning, only need to be in crankcase or axis
The mounting hole set and coordinated with stator is opened up on the outside of bearing, and offers screw hole in crankshaft end, to be greatly saved
Transformation and input cost, direct-drive type of the present invention can be installed by carrying out simple transformation and upgrade to existing crank type booster pump
Motor.
