The invention relates to a high-temperature-resisting submerged pump which comprises a pump shell, a bearing chamber and a rotating shaft. The rotating shaft is connected with the bearing chamber in a penetrating manner. The bearing chamber is installed in the pump shell. The outer portion of the bearing chamber is sleeved with a cooling cavity. A water inlet pipe and a water outlet pipe are arranged on the two sides of the cooling cavity correspondingly. The water inlet pipe and the water outlet pipe stretch out from the pump shell. One or more oil seals are arranged between the rotating shaft and the bottom of the bearing chamber for sealing, and one or more oil seals are arranged between the rotating shaft and the inner bottom face of the cooling cavity for sealing.
Description
technical field [0001] The invention relates to a submerged pump, in particular to a high temperature resistant submerged pump for cooling a bearing chamber. Background technique [0002] When the medium conveyed by the submerged pump is high-temperature molten salt, when the transmission shaft is immersed in high-temperature liquid for a long time, due to the heat transfer effect of the metal shaft, the high temperature will be transmitted to the bearing along the shaft, causing the temperature of the bearing to rise, and the bearing fail. Contents of the invention [0003] The object of the present invention is to provide a high temperature resistant submerged pump. [0004] The technical solution adopted by the present invention is: a high temperature resistant submerged pump, including a pump casing, a bearing chamber and a rotating shaft, the rotating shaft passes through the bearing chamber, the bearing chamber is installed in the pump casing, and the outer part of ...
