Description
Technical field
The utility model is related to electrodynamic pump, and in particular to a kind of electric fluid pump.
Background technology
Electric fluid pump use occasion is a lot, such as, and automobile maintenance industry is accomplished by using electronic when to auto repair
Pump, with the used oil in extracting replacing automobile.
Electric fluid pump, is made up of from structure pump head and motor two parts, and pump head includes pump head shell and is located at
Pump rotating shaft and two gears in pump head shell, and pump head shell is provided with inlet and liquid outlet；Also, existing pump head is to divide with motor
Body structure, is connected between the pump rotating shaft of pump head and the output shaft of motor through a shaft coupling, and the pump head shell and motor housing of pump head
It is fixedly connected through a connecting seat body, through hole is set in connecting seat body and accommodates the shaft coupling.Above-mentioned prior art, exist it is following not
Foot：Pump head is Split type structure with motor, between the two provided with shaft coupling, causes the axial dimension of electrodynamic pump longer, is taken up space big.
The content of the invention
The utility model purpose is to provide a kind of electric fluid pump, to solve prior art axial dimension length, take up space greatly
The problem of.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of electric fluid pump, including a pump housing,
The pump housing one end slots to form pump chamber, and the other end sets motor installation step hole；Gear or pump rotor are set in the pump chamber；The electricity
It is embedded in machine installation step hole in a motor stator, motor stator and sets rotor, the rotating shaft of rotor, which is worn to pump chamber and gear or pump, is turned
Son drive connection；The end cap for setting pump chamber of the pump housing sets a capping, with pump chamber described in lidstock, and the pump housing sets motor
The one end in installation step hole connects an electric motor end cap, and the electric motor end cap sets motor stator cover.
In such scheme, in the capping correspondence pump chamber offer the first import reserve blind hole and first outlet reserve it is blind
Hole, and offer the reserved blind hole of the second import and the reserved blind hole of second outlet in the correspondence pump chamber that radially also corresponds to of the pump housing.
The utility model has advantages below：The utility model compact conformation, compact takes up space small, is easily installed
Use；And the reserved blind hole of blind hole and outlet is reserved due to being equipped with import on radial and axial in the pump housing, client can be according to need
Desired blind hole is selected to carry out drilling and tapping, i.e., radial and axial both of which can connect turnover pipeline, select freedom and flexibility.

Embodiment
Below in conjunction with the accompanying drawings and embodiment is further described to the utility model：
Embodiment：Referring to shown in Fig. 1 and Fig. 2：
A kind of electric fluid pump, including a pump housing 1, the one end of the pump housing 1 slot to form pump chamber 2, and the other end sets motor installation
Stepped hole 3.Set to be embedded in a motor stator 5, motor stator 5 in gear 4, motor installation step hole 3 in the pump chamber 2 and set rotor
6, the rotating shaft 7 of rotor 6 is worn to pump chamber 2 to be connected with gear 4.The end cap for setting pump chamber 2 of the pump housing 1 sets a capping 8, with
The sealing of capping 8 pump chamber 2, and one end for setting motor installation step hole 3 of the pump housing 1 connects an electric motor end cap 9, the electric motor end cap
9 set the cover of motor stator 5.The capping 8 is fixedly connected by screw with the pump housing 1, and electric motor end cap 9 is also by screw and the pump housing
1 is fixedly connected.
Correspondence pump chamber 2, which offers the first import and reserves blind hole 10 and first outlet, in the capping 8 reserves blind hole 11, and
The correspondence pump chamber that radially also corresponds to of the pump housing offers the reserved blind hole 12 of the second import and the reserved blind hole 13 of second outlet.
In use, client can select desired blind hole to carry out drilling and tapping as needed, i.e., radial and axial both of which can
To connect turnover pipeline, freedom and flexibility are selected.
Above-described embodiment citing is a gear pump structure, can also be actually cycloid pump configuration, as long as gear 4 is converted
For pump rotor, the shape of pump chamber 2 is accordingly changed.
Above-described embodiment is only to illustrate technical concept of the present utility model and feature, and its object is to allow be familiar with technique
Personage can understand content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.
All equivalent change or modifications made according to the utility model Spirit Essence, should all cover protection domain of the present utility model it
It is interior.
