Problems solved by technology

[0002] At present, all kinds of water pump bearing devices in the market adopt a sealed oil lubrication structure, and the bearing and bearing housing are prone to heat during operation, especially under high temperature conditions; however, there is currently no effective cooling device for this part, or The cooling devices are all simple straight tubes with water passing through them. Due to the short circulation time of the cold water in the straight tube structure, the cooling effect is not ideal, and further improvement is needed.

Embodiment Construction

[0010] The present invention is arranged in the space formed by the suspension body 1 and the bearing seat 2 which are arranged in a split form, and is in the form of a spiral tube 3 , and its inlet 4 and outlet 5 both protrude from the bearing seat 2 .

[0011] The spiral pipe 3 is a double-layer sleeve type, the inner layer is water-through, and the outer layer is ventilated.

[0012] The pump is externally provided with a cooling device 6 arranged between the inlet 4 and the outlet 5 .

[0013] The inner layer of the spiral tube 3 of the present invention passes cold water, and the outer layer passes cold air to realize double-layer cooling, and the cooling effect is very good.

[0014] The present invention is equipped with a cooling device arranged between the inlet 4 and the outlet 5 outside the pump. The heat absorbed by the cooling water after passing through the pump bearing can pass through the heat exchange with the cooling device 6, so that the water can be circula...

Abstract

The invention relates to a pump bearing cooler. The pump bearing cooler disposed in space formed by a suspension member and a bearing block which are split is in a spiral tube form; an inlet of the pump bearing cooler and an outlet thereof both extend out of the bearing block. The pump bearing cooler is simple in structure and capable of effectively cooling a pump bearing.

Description

technical field [0001] The invention relates to a pump bearing cooling device, which belongs to the technical field of pumps. Background technique [0002] At present, all kinds of water pump bearing devices in the market adopt a sealed oil lubrication structure, and the bearing and bearing housing are prone to heat during operation, especially under high temperature conditions; however, there is currently no effective cooling device for this part, or The cooling devices are all simple straight tubes with water passing through them. Due to the short circulation time of the cold water in the straight tube structure, the cooling effect is not ideal, and further improvement is needed. Contents of the invention [0003] The purpose of the present invention is to provide a pump bearing cooling device with a simple structure and capable of effectively cooling the pump bearing. [0004] For this reason, the technical scheme adopted by the present invention is: the present invent...
