Water cooling energy-saving mute pump

Abstract

The invention provides a water cooling energy-saving mute pump. The water cooling energy-saving mute pump comprises a pump body, a submersible motor is arranged in the pump body and vertically connected with a flow guiding bracket, the flow guiding bracket is located over the submersible motor, the submersible motor is located at the lower end of the pump body and fixed to a flow guiding base, theside face of the flow guiding base is provided with an inlet, and the submersible motor is connected with the top of the flow guiding base in a sealing mode through a second outer cylinder used for motor cooling flow passing; a shaft body of the submersible motor is connected with a pump shaft of the pump body through a spline connecting block, at least three impellers which are vertically arranged are arranged on the outer side of the pump shaft, every two vertical adjacent impellers communicate with each other through a flow guiding part, the second outer cylinder and a first outer cylinderare fixed through bolts, and the first outer cylinder is located outside the flow guiding parts; and an outlet of the pump body is formed in the top, a pump cover is arranged at the outlet of the pump body, and a flange is movably connected to the pump cover.

Description

technical field [0001] The invention relates to mechanical equipment, in particular to a water-cooled, energy-saving and silent pump structure. Background technique [0002] With the increasing number of high-rise buildings, in order to meet the normal daily water supply of high-rise residents, a pressurization system is usually added between the municipal pipe network and the users. Low efficiency has seriously affected people's normal working and living environment and physical health. At present, the prime movers of water supply pumps in residential areas are generally motors, and the cooling method of the motors is generally air-cooled. As we all know, most of the noise caused by the motor fan when a water pump unit is running, followed by the impact of flowing water. The sound of water" is also inevitable. In view of the above reasons, it is obvious that it is not feasible for the motor to cool down by fan blades and reduce noise at the same time. However, some manuf...

Problems solved by technology

However, some manufacturers also use water cooling, usually by cooling the motor casing, and the installation method is generally that the water pump is on the bottom and the motor is on the top. The water pressure from the pump to the motor is generally high, and the pipeline is very thin. This brings great difficulty to the sealing of the motor. If it is not serious, the motor will leak water and burn the motor. When encountering hard water, the pouring pipe is easy to foul and block. Although there is no water leakage, the motor heats up too high , also cause the motor to burn out, and at the same time, it also brings a considerable degree of inconvenience to the maintenance personnel
