Description

  The present invention relates to a vertical pump facility, and more particularly, to a vertical pump facility that supports the equipment load of a vertical pump on a plurality of floors and is resistant to vibration.

  Conventionally, pump stations including this type of vertical shaft pump include a one-bed pump station having only a pump floor above the water tank and a two-bed pump station having a pump floor and a prime mover floor above the water tank. As shown in FIG. 1, the one-bed pump station is provided with a pump floor 102 above the water tank 101, and equipment loads such as the pump 103 and the pumping pipe 104 are supported on the pump floor 102 via the pump base 105. Further, the load of the motor 106 such as a motor and a speed reducer is also supported by the pump floor 102 via the motor frame 107.

  In the two-bed pump station, as shown in FIG. 2, a pump floor 102 and a motor floor 108 are provided above the water tank 101, and equipment loads such as the pump 103 and the pump pipe 104 are pumped through the pump base 105. The load of the motor 106 such as a motor and a speed reducer is supported by the motor floor 108 via the motor frame 109.

  In the above-described one-floor type pump station, equipment loads such as the pump 103 and the pumping pipe 104 and loads of the prime mover 106 such as a motor and a speed reducer are concentrated on the pump floor 102. Therefore, it is necessary to make the pump floor 102 strong. There is. Further, when the pump 103 and the pumping pipe 104 are long, the load is supported at one place, which is disadvantageous for vibration.

  Moreover, in the said 2 floor type pump station, since the load of the pump 103 is supported by the vertical pumping pipe 104, there exists a problem that it is easy to vibrate when the pumping pipe 104 is long. Further, when the prime mover 106 has a hydraulic thrust, there is a problem that a large thrust load acts on the prime mover floor 108.

  The present invention has been made in view of the above points, and in a two-bed pump station, even when the prime mover has a hydraulic thrust, the hydraulic thrust load is not concentrated on the prime mover floor, but is distributed on the pump floor and the prime mover floor. It is an object of the present invention to provide a vertical shaft pumping facility that can support and is strong against vibrations and can equally distribute equipment loads on two floors.

  In order to solve the above-mentioned problems, the invention described in claim 1 is directed to a vertical shaft pump facility in which a vertical shaft pump is installed in a two-bed pump station having a prime mover floor and a pump floor above a water tank. A prime mover frame is integrally formed, the pump frame is installed on the pump floor, the prime mover frame is installed on the prime mover floor, and the load of the vertical shaft pump is distributed and supported by the prime mover floor and the pump floor.

  The invention according to claim 2 is characterized in that, in the vertical shaft pump equipment according to claim 1, elastic bodies are interposed between the pump base and the pump floor and between the prime mover base and the prime mover floor, respectively.

  The invention according to claim 3 is characterized in that, in the vertical shaft pump equipment according to claim 2, the load applied to each floor can be arbitrarily set by changing the elasticity of each elastic body.

  According to a fourth aspect of the present invention, in the vertical shaft pump facility according to the first aspect, a support member is provided on the bell mouth and / or pumping pipe of the vertical pump, and the bell mouth and / or pump pipe is provided via the support member. Is dispersed and supported by the water tank wall.

  According to a fifth aspect of the present invention, in the vertical shaft pump facility according to the fourth aspect of the present invention, an elastic body is interposed between the bell mouth and / or the pumping pipe and the aquarium wall.

  According to the first aspect of the present invention, the pump frame of the vertical shaft and the motor frame of the prime mover are integrally configured, and the load of the vertical shaft pump is distributed and supported by the prime mover floor and the pump floor. When the prime mover has, the hydraulic thrust acts on the prime mover floor and the pump floor, and the load is distributed. Further, since the equipment load is supported at two places, it is strong against vibration.

  According to invention of Claim 2 and 3, an elastic body is interposed between the pump mount and the pump floor and between the prime mover mount and the prime mover floor, respectively, and by changing the elasticity of each elastic body, the load of the equipment is reduced to the two floors. It can be evenly distributed on the surface.

  According to the fourth aspect of the present invention, the load of the vertical shaft pump can be further distributed and supported by providing the bell mouth and / or the pumping pipe with the support member and supporting it with the water tank wall.

  According to invention of Claim 5, the load of an apparatus can be further disperse | distributed and equally distributed by interposing an elastic body between a bell mouth and / or a pumping pipe and a water tank wall.

FIG. 3 is a diagram showing a configuration of a vertical shaft pump facility according to the present invention. In FIG. 3, reference numeral 1 denotes a suction water tank, and a pump floor 2 and a prime mover floor 8 are provided above the suction water tank. Reference numeral 5 denotes a pump mount on which the pump 3 and the pumping pipe 4 and the like are mounted. Reference numeral 7 denotes a prime mover mount on which a prime mover 6 for driving the pump 3 including a motor, a speed reducer and the like is mounted. The prime mover stand 7 is integrally connected to the bent portion of the pumped water pipe 4 by a connecting member 9. That is, the prime mover base 7 and the pump base 5 are integrally configured via the connecting member 9 and the pumping pipe 4. The pump mount 5 is supported on the pump floor 2 with a spring 10 interposed therebetween, and the prime mover mount 7 is supported on the prime mover floor 8 with a spring 11 interposed therebetween.

  As described above, the pump base 5 and the prime mover base 7 are integrally configured via the connecting member 9 and the pumping pipe 4, and are supported by the pump floor 2 and the prime mover floor 8, respectively. The floor 8 is distributed and supported. Further, when the prime mover 6 has a hydraulic thrust received by rotating the pump (force to lower the pump 3), the hydraulic thrust is also dispersed in the pump floor 2 and the prime mover floor 8. Further, the elasticity (spring hardness) of the spring 11 interposed between the prime mover floor 8 and the prime mover base 7 and the elasticity (spring hardness) of the spring 10 interposed between the pump floor 2 and the pump base 5. Is adjusted so that the equipment load can be evenly distributed between the motor floor 8 and the pump floor 2.

It becomes possible to support the load in a distributed manner. Also in this case, the equipment load can be evenly distributed by adjusting the elasticity (spring hardness) of the springs 10, 11, and 13. Further, by arbitrarily adjusting the elasticity of each spring, the load received by each floor can be arbitrarily adjusted. Although not shown, if a support member is also provided in the pumping pipe 4, and supported by interposing a spring between the support member and the wall surface of the suction water tank 1 (including the bottom floor surface of the suction water tank 1), Further, the load can be dispersed.
