进口双相钢立式液下泵哪家品牌好

进口双相钢立式液下泵Product description:

进口双相钢立式液下泵The pump includes a pump shaft and a pump body. The pump body is arranged at the lower end of the pump shaft. A high-pressure outlet is arranged on the pump body, a liquid outlet pipe is arranged at the high-pressure outlet, a water bearing and a bearing sleeve are arranged at the connection between the pump body and the pump shaft, the water bearing is matched with the bearing sleeve, the material of the water bearing is flexible, the material of the bearing sleeve is rigid, and the liquid outlet pipe is provided with a first flushing pipe for connecting the water bearing. The underwater bearing is set as flexible material, while the bearing sleeve is still made of rigid material, so that the gap between the two can be adjusted to very small, the friction is small, and the occurrence rate of bearing seizure is reduced. Through the setting of the first flushing pipe, the medium can be introduced into the underwater bearing from the high-pressure outlet, effectively taking away the heat of sliding temperature rise of the underwater bearing and lubricating the underwater bearing, thus improving the volumetric efficiency.（仅供参考）
