The through-hole is formed in the width of the characterized in that it further comprises a cover flow pipe for transporting the fluid transferred through the flow pipe.

Meanwhile, a front shaft bearing is further included in which a motor shaft is inserted into and coupled to the center of the motor front cover, and the motor shaft of the center of the motor rear cover has a predetermined aperture so that the motor shaft can be smoothly rotated in the penetrating portion. It is characterized in that the rear shaft bearing is further included.

On the other hand, a flange is formed at one end of the motor casing at a position coupled to the connection expansion pipe and the connection expansion pipe, respectively, and is coupled to the flange and coupled to the motor rear cover and the motor rear cover. Flanges are formed at one end thereof, and the flanges are coupled to each other, and a flange is further formed at the other end of the motor rear cover, and a fastening groove is further formed at a position corresponding to the motor rear cover flange of the pump casing. It is characterized in that it is screwed with the rear cover flange.

The inline pump according to the present invention as described above is applicable to the development of the pump can be used for land, it can also be used for underwater use in the economical aspect than the existing inline pressure pump of claim 2, The length of the motor pump can be greatly reduced to reduce the size of the structure, which shortens the construction period.

It is a structural diagram of the heart pump according to the prior art. It is a structural diagram of a volute pump according to the prior art. A structural diagram of an inline pump according to the present invention. It is an external view of the inline pump according to the present invention.

Hereinafter, the structure of the inline pump according to the present invention will be described in detail with reference to the drawings.

3 is a structural diagram of an inline pump according to the present invention, and FIG. 4 is an external view of an inline volute pump according to the present invention.

The inline pump according to the present invention includes a suction part 310, a motor part 320, and a pump part 330 as main parts.

First, the suction part 310 is composed of a suction port (not shown) and a connection expansion pipe 311 for transferring the fluid, and the flanges 411 and 412 for coupling with the casing 321 of the motor on the outer circumferential surface. It includes more.

The motor 320 is provided with a motor main body 323 therein, and the fluid transferred through the connection expansion pipe 311 not only seals the motor main body 323 on the outer circumferential surface of the motor main body 323. A donut-shaped motor casing 321 having a flow path tube 322 formed therein is provided to be transferred to the unit 330.

In addition, a motor front cover 313 and a motor rear cover 325 are further provided. The motor front cover 313 connects the motor body 323 to seal the motor body 323 from the fluid of the expansion tube 311. The motor rear cover 325 seals the motor main body 323 from the fluid of the pump main body 323.

On the other hand, the motor front cover 313 is further connected to the motor to rotate smoothly without a shaft (not shown) for driving the impeller 332 of the pump unit 330, for example a bearing, for example a bearing It is formed to couple the shaft to the rotating body.

On the other hand, the central portion of the motor rear cover 325 is through, the shaft is coupled to the through-hole portion, the rotating body, such as a bearing so that the shaft is smoothly rotatable as well as not flowing when the shaft is rotated This is further provided.

In addition, a mechanical seal 326 is further provided in the direction of the pump unit 330 of the motor rear cover 325 to block the fluid that can flow through the shaft.

In addition, the rear cover flow path tube 324 is further formed in the motor rear cover 325 so as to transfer the fluid transferred through the flow path tube 322 formed in the motor casing 321 so that the fluid is pumped 330. It forms a passage for transport to

The motor casing 321 and the rear cover flow path tube 324 are further formed with a flange on the outer circumferential surface of the front and rear ends to seal and couple the flanges 421 and 422 to protect the motor body 323 from external fluid. In addition, in performing repairs or inspections, it is possible to disassemble the device, not to disassemble the whole.
