Abstract

The invention relates to a thermal insulation type high-temperature pump which is mainly composed of a motor, a sealing assembly, a normal-temperature pump body and a high-temperature pump body. The normal-temperature pump body and the high-temperature pump body are coaxial and share one motor, the normal-temperature pump body is disposed between the motor and the high-temperature pump body, the sealing assembly is disposed between the motor and the normal-temperature pump body, a second sealing assembly or quasi sealing assembly is disposed between the normal-temperature pump body and the high-temperature pump body, or no sealing assembly is disposed on the normal-temperature pump body and the high-temperature pump body; and the normal-temperature pump body and the high-temperature pump body are each provided with an independent inlet and an independent outlet. Since one normal-temperature pump body is disposed between the sealing assembly in front of the motor and the high-temperature pump body, a thermal insulation effect is realized, and the problems of high-temperature deformation, leakage and the like of the sealing assembly are effectively avoided. The thermal insulation type high-temperature pump can work for a long time under working conditions of high temperature (about 250 DEG C) and high pressure and is mainly applied to high-temperature high-pressure occasions suchas a tubular steam module boiler.

Description

technical field [0001] The invention relates to a pump, in particular to a heat-insulated high-temperature pump resistant to high temperature and high pressure. Background technique [0002] In the prior art, the seals of the pump are easily worn and deformed under high temperature and high pressure conditions, resulting in liquid leakage. At present, the high-temperature pumps used in tubular steam module boilers have a very high failure rate when the operating temperature exceeds 150 degrees. Therefore, high-temperature pumps that can withstand operating temperatures above 180 degrees for a long time have broad market prospects. [0003] The purpose of the present invention is to manufacture a heat-insulated high-temperature pump, which can withstand a working temperature of more than 200 degrees for a long time, and is mainly used in high-temperature and high-pressure occasions such as through-flow steam module boilers. Contents of the invention [0004] The present in...
