Abstract

The invention discloses a safe and stable high temperature resistant hot water circulating pump system, which comprises a hot water circulating pump, a mechanical seal, a pressure control valve (9), a micro steam turbine (10), a screw pump (11), a heat exchanger ( 14), the jet device (16), is characterized in that: the outlet of the hot water circulating pump is connected with the threaded pump through the first pipeline, the threaded pump is connected with the heat exchanger through the pipeline, and the heat exchanger is connected with the jet device through the pipeline. Connection, the drive shaft of the screw pump is connected with the micro-turbine, the micro-turbine is connected with the first pipeline through the pipeline, the pressure control valve is connected between the micro-turbine and the first pipeline, the micro-turbine is connected with the jet device through the pipeline, and the jet device The second line is connected to the mechanical seal. It is mainly in shutdown and standby, the mechanical seal cooling water is still circulating to ensure that the mechanical seal is not damaged at the allowable working temperature; in addition, it can improve the pressure stability at the outlet of the impeller, thereby improving the output pressure stability of the hot water circulating pump. sex.

Description

technical field [0001] The invention relates to the technical field of hot water circulating pump systems, in particular to a safe and stable high temperature resistant hot water circulating pump system. Background technique [0002] The design of the mechanical seal of the hot water circulating pump in the prior art only considers the cooling of the mechanical seal cavity during operation. The temperature of the group is the same, when the medium temperature is ≥ 220 ℃, it is easy to cause damage to the mechanical seal. [0003] Existing hot water circulating pumps usually monitor and warn the temperature of the mechanical seal cavity during application, and monitor whether the mechanical seal is leaking by setting reasonable detection measures, so as to avoid casualties and shutdown of the production line when a problem occurs before remediation and other security incidents. In the prior art, the real-time operation status of the hot water circulating pump system is moni...
