Description
The present invention relates to an inline pump, and more particularly, to a structure of an inline pump that can be used for land and can also be used underwater.
Conventionally, the heart pump is installed and used in the underground structure, but the length of the structure is increased according to the application of the heart motor submersible motor pump, the size of the structure is increased, the volute pump used for land is not suitable for underwater It is.
These cardiac pumps are installed in the pipeline so that in the event of a failure, it is not possible to immediately identify which parts are worn out or broken, other than a short circuit of the winding.
Therefore, usually, only the flow path is connected to the pipe line, and the motor uses a pump with a casing formed therein to be exposed to the outside. However, the structure of these parts is a structure in which the casing and the flow path cannot be separated. In the end, it takes a lot of repair period because it has to be taken out of the underground pressurization chamber, transported to the repair shop, and then disassembled and repaired as a whole.
In addition, due to the large number of parts, it is not inconvenient to consider that it is impossible to repair unless it is an expert.
Therefore, in recent years, it is installed horizontally used, but eventually the number of parts to 40 kinds of complex and there is a disadvantage that the wear of the bearings and metals are severe, and the troubleshooting of these things is complicated.
In addition, the casing of the same horsepower is different, because the pump use is different due to the difference in the flow rate and the head of each water supply area, it is impossible to replace the urgent replacement of the casing length.
The inline pump according to the present invention for solving the above problems can be used for land use, to provide an inline pump that can be used for underwater use.
Inline pump according to the present invention is to reduce the length of the motor pump significantly to reduce the size of the structure to provide an easy in-line pump at the time of construction.
Inline volute pump according to the present invention for solving the above problems is connected to the expansion pipe including a suction inlet; A motor front cover for sealing the motor at a connection expansion side; A donut shaped moker casing into which the motor is inserted; A motor rear cover for sealing the motor in the discharge pipe by forming a shaft through groove through which a shaft of the motor passes through a central axis thereof; A mechanical seal for penetrating the motor shaft and sealing the motor including the motor rear cover; A pump casing coupled to the rear cover of the motor and having a through hole through which fluid is transferred; An impeller provided inside the pump casing and connected to a motor shaft to transfer fluid to the discharge tube, and an impeller nut for fixing the impeller to the shaft; A through-hole is formed in a direction perpendicular to the motor shaft axis, characterized in that the discharge pipe for discharging the fluid pressurized by the impeller is provided.
The motor casing further includes a motor casing flow passage through which a through hole is formed at a predetermined width along the circumferential surface to transfer the fluid introduced through the connection expansion pipe, and the inside of the motor rear cover is provided along the circumferential surface. 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.
Hereinafter, the structure of the inline pump according to the present invention will be described in detail with reference to the drawings.
