Inner network double state heat conduction permanent magnet shield pipe middle pump

Abstract

The invention discloses an inner network double state heat conduction permanent magnet shield pipe middle pump, and belongs to the field of pipe middle pumps. The inner network double state heat conduction permanent magnet shield pipe middle pump can speed up heat conduction and heat absorption efficiency of the inner part of an epoxy resin protective layer and extend the service life through arrangement of a three-dimensional heat conduction network and the epoxy resin protective layer, at the same time, when shaking occurs in the process of transportation or use, through the three-dimensional heat conduction network, force can be dispersed to the inner part of the epoxy resin protective layer, pressing is even, mechanical protection effects on inner structures of the pipe middle pumps are effectively improved, when vibrating or shaking, a solid heat conduction structure of the epoxy resin protective layer in a motor can effectively avoid secondary impacts on the internal structures caused by the flow of cold liquid, the mechanical protection effects are further improved, the service life is prolonged, the cold liquid outside the motor is clean water, and is safe and environmentalprotection; at the same time, heat generated by permanent magnets is far lower than that of ordinary asynchronous motors, temperature rise is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of pump-in-pipe, more specifically, relates to a pump-in-pipe with an inner mesh bi-state thermal conduction permanent magnet shield. Background technique [0002] Pump-in-pipe water supply equipment is a new type of water supply equipment based on ordinary non-negative pressure water supply equipment. water supply equipment . In addition to having all the functional features of ordinary non-negative pressure water supply equipment, this product also shows the design concept of "environmental protection and hygiene, low noise, and no disturbance to the people". The motor is selected from all Stainless steel The water-filled motor has no pollution to the water quality, and its main flow parts are made of 304 stainless steel and other food-grade materials. The equipment structure forms a closed system, so the operation is noiseless and the water quality is pollution-free. It is not difficult to see that this produc...

Problems solved by technology

[0003] During use, the motor inside the pump-in-pipe will heat up, which will reduce the overall working efficiency of the pump-in-pipe. Although the pump-in-pipe is used in water and has better heat dissipation, the motor inside the pump-in-pipe is to prevent it from being exposed to water. The problem of damage is usually sealed and packaged in the casing of the pump in pipe, and due to the effect of sealing materials, it has a certain distance from the outside water. During the process of heat transfer from the motor to the casing of the pump in pipe and taken away by the water flow, The heat conduction efficiency is poor, that is, the heat is easy to accumulate in the shielding chamber of the pump in the pipe. The medium for temperature transmission in the shielding chamber is usually water or oil. Due to water cooling or oil cooling, when shaking occurs during transportation or use, there will be Leakage of coolant may cause pollution of the water body and the surrounding environment. At the same time, when this heat dissipation method is shaken or vibrated, the internal water or oil will flow greatly, which will have a certain impact on the internal mechanical components.
