Concentric positioning mechanism for energy-saving water pump

Abstract

The invention relates to the technical field of related structures of energy-saving water pumps, and discloses a concentric positioning mechanism for an energy-saving water pump. The concentric positioning mechanism for the energy-saving water pump comprises a motor and an impeller shell, a lengthened output shaft is arranged at the output end of the motor, the motor and the impeller shell are connected with each other through a positioning cylinder, a port of the positioning cylinder communicates with the impeller shell, two positioning bearings are symmetrically mounted in an inner cavity of the positioning cylinder, a vacuum one-way valve communicating with the inner cavity of the positioning cylinder is mounted on the positioning cylinder, a threaded oil injection opening is formed in the positioning cylinder, an oil injection plug is mounted on the threaded oil injection opening in a threaded mode, and a lengthened output shaft of the motor penetrates through the positioning cylinder and extends to an inner cavity of the impeller shell. According to the concentric positioning mechanism for the energy-saving water pump, the bearing stress of the structure is increased, the surface corrosion degree of the structure is reduced, and the matched friction force between the structures is reduced, so that the stability of the concentric positioning mechanism for the energy-saving water pump is effectively improved, the maintenance and operation intensity of related operators is reduced, and the service life of cooperation between equipment structures is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of structures related to energy-saving water pumps, in particular to a concentric positioning mechanism for energy-saving water pumps. Background technique [0002] Energy-saving water pumps, as the name implies, are water pumps that can save energy consumption, improve the high-efficiency operation of the water pump itself, and reduce energy consumption. Example: The average power consumption of ordinary water pumps is 100 degrees per hour, and under the same working conditions, energy-saving pumps are 80 degrees per hour or less. Energy-saving water pumps are composed of two parts, the motor and the pump body. Couplings and bearing housings and other related connecting parts are linked and connected. In actual production and life, the output shaft of the motor drives the impeller of the pump body to rotate to generate negative pressure to extract fluid. Rotational stress, the impeller disc transmits the r...
