Technical field
The utility model is related to a kind of latent oil electric motor for pump comprising end cap, shell, the stator pack of setting inside the shell
Part, shaft and the rotor assembly in shaft.
Background technology
Oil-immersed pump is usually made of two parts, and a part is pump ontology, and another part is the motor for driving pump ontology operating.
Motor for oil-immersed pump is usually shield electric machine, and traditional shield electric machine is sealed after being squeezed with O-ring, when using one section
Between after O-ring seal aging will appear leak source, generate security risk.
Invention content
The problems of for the above-mentioned prior art, the purpose of this utility model is to provide a kind of no leak source, anti-inflammable
The good latent oil electric motor for pump of explosive performance.
In order to achieve the above objectives, technical solution used by the utility model is：
A kind of latent oil electric motor for pump, including end cap, shell, setting stator module inside the shell, shaft, it is mounted on shaft
On rotor assembly and be close to the liner of stator module inner wall setting, the end cap is separately positioned on shell both ends, the end cap
It is provided with sealing cover between shell, enclosure is made to form a closed chamber, rotor assembly is located in the closed chamber, the liner
Both ends extend out at sealing cover, and are welded with sealing cover, and the shaft is provided at both ends with sealing ring, and the sealing ring is solid
It is scheduled on end cap.
Preferably, the liner is 304 stainless steel inner containers.
Preferably, the rotor assembly and stator module inner cavity are filled with high grade transformer oil.
Preferably, the sealing ring is anti-corrosion oil resistant lip-type packing.
Preferably, described shaft one end is stretched out, which adds impeller.
The utility model has the beneficial effects that：The liner and sealing cover of the latent oil electric motor for pump weld, no leak source, therefore can
High grade transformer oil is filled in rotor assembly and stator module inner cavity, can preferably play the role of insulation lubrication, avoid
The security risk of electric leakage prevents that inflammable and explosive, resistant to strong corrosion performance is more outstanding.
The utility model is described in further detail with reference to the accompanying drawings and examples.

Courage 6 and sealing cover 11 weld, and stator module 3 is made to be integrally formed with liner 6, no leak source, double protection, therefore, can be
Rotor assembly 5 and 3 inner cavity of stator module fill high grade transformer oil, can preferably play the role of insulation lubrication, avoid
The security risk of electric leakage prevents that inflammable and explosive, resistant to strong corrosion performance is more outstanding, and shaft 4 is provided at both ends with anti-corrosion oil resistant lip
Sealing ring 41, anti-corrosion oil resistant lip-type packing 41 are fixed on end cap 1, which seals,
Prevent the leakage of high grade hydraulic oil.
Furthermore, it is understood that be provided with line outlet on shell 2, outlet joint 21 is installed at the line outlet, cable 22 from
Outlet joint 21 stretches out, and is cast with fluid sealant between cable 22 and outlet joint 21.
Furthermore 4 one end of shaft is stretched out, which adds impeller 42, plays and various media are pushed flowing and motor
The effect of cooling.
Although the utility model is to be described with reference to specific embodiments, this description is not meant to the utility model
It is construed as limiting.With reference to the description of the utility model, other variations of the disclosed embodiments are all for those skilled in the art
It is anticipated that, such variation should belong in appended claims limited range.
