Excellent-performance upper-lying type axial flow pump device for motor and application method thereof

Abstract

The invention discloses an excellent-performance upper-lying type axial flow pump device for a motor and an application method thereof, and belongs to the technical field of water engineering pump station. The excellent-performance upper-lying type axial flow pump device for the motor and the application method thereof are characterized in that an inlet conduit, an axial flow pump body and an outlet conduit are arranged in a vertical plane; the motor which is installed in a lying type is arranged above the inlet conduit; the inlet conduit is designed to a curved shape, so that a pump shaft penetrates through the inlet conduit from the front portion of a pump body impeller and is connected with a bearing, a gear case and the motor in sequence; the inlet conduit is divided into a linear line section and a curved section, and the descend angle and length of the bottom edge of the linear section can be adjusted in a certain range; the outlet conduit is divided into a curved section and a linear section; the ascending angle and length of the bottom edge of the linear section can be adjusted in a certain range; the sizes of pump devices are all expressed by relative values (the diameter D of the water pump impeller serves as a reference value). The excellent-performance upper-lying type axial flow pump device for the motor has the advantages that the hydraulic performance is excellent, the structure is simple, the heat dissipation condition of the motor is good, the unit installation and maintenance are convenient, and the project cost is low.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering pumping stations, and in particular relates to a motor front-mounted horizontal axial-flow pump device with excellent performance and an application method thereof, which is mainly used to guide engineers and technicians in designing a motor-fronted upper-horizontal pump device with excellent hydraulic performance. The axial flow pump device ensures the quality of the design of the horizontal axial flow pump device in front of the motor of the large horizontal low head pumping station. Background technique [0002] Large-scale low-head pumping stations are widely used in many fields that have a great impact on my country's social and economic development, such as water resource allocation, agricultural irrigation and drainage, water environment management, and urban drainage. Bulb-type tubular pumps with good hydraulic performance are mostly used in large ultra-low-lift pumpi...

AI Technical Summary

Problems solved by technology

Since the size of the bulb body arranged in the flow channel is greatly limited, the space required for equipment layout and maintenance is very tight, and it also brings defects such as complex structure, poor heat dissipation conditions of the motor, and high cost.
