Vertical single-stage pipeline centrifugal pump

Abstract

The invention relates to the technical field of centrifugal pumps, in particular to a vertical single-stage pipeline centrifugal pump. The pump comprises a pipe body, the top of the pipe body is fixedly connected with a connecting frame, the top of the connecting frame is fixedly connected with a motor, an output shaft of the motor is fixedly connected with a transmission shaft, the transmission shaft is fixedly connected with pump blades, the bottom of the pipe body is fixedly connected with a bearing, the bottom end of the transmission shaft is inserted into the bearing, the bottom of the pipe body is fixedly connected with a leveling mechanism, the leveling mechanism comprises a mounting seat, and the mounting seat is fixedly connected to the bottom of the pipe body. The leveling mechanism is used, the height of the four corners of the device can be accurately adjusted, and the adverse factor that the specification of an existing gasket is fixed can be avoided; after the height of the device is adjusted, a second gasket and a first gasket are used for being clamped into a rack to level the bottom of the mounting seat, and the device is more accurate and more convenient to level; a buffering mechanism is arranged, and the kinetic energy on the transmission shaft can be absorbed when the transmission shaft shakes.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a vertical single-stage pipeline centrifugal pump. Background technique [0002] Centrifugal pumps work by rotating the impeller to cause the water to move centrifugally. Before starting the pump, the pump casing and the suction pipe must be filled with water, and then the motor is started to drive the impeller and the water to rotate at a high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows through the volute pump casing. The channel flows into the pressure water pipeline of the pump, while the centrifugal pump is divided into horizontal and vertical centrifugal pumps. The vertical centrifugal pump has a small footprint and is more suitable for places with limited space. [0003] Existing patent (notification number: CN110296084B), the invention discloses a vertical centrifugal pump, including a pump body, a pum...

Problems solved by technology

[0005] The pump shaft will shake during the working process, which will cause wear to the bearings and other components, resulting in frequent disassembly and maintenance of the device, reducing the life of the device, and when the device is not installed properly, the shaking of the pump shaft will be more obvious and severe
