Abstract

The invention discloses a water-saving hot water circulating pump which comprises a pump body, a motor and a machine shell, wherein the motor is connected with the pump body, and the machine shell is arranged below the pump body. The pump body comprises a pump shaft and an impeller which is arranged around the pump shaft. The motor is connected with the pump shaft of the pump body through a coupler, a seal chamber is formed between the pump body and the machine shell, and a throttling by-pass pipe is connected on the seal chamber. According to the mode, the water-saving hot water circulating pump can ensure circular flow of water flow in the pump body, reduces loss of water flow passing through the pump body, plays a role in water conservation, and can accurately control the water flow in the pump body.

Description

technical field [0001] The invention relates to the field of hot water circulating pumps, in particular to a water-saving hot water circulating pump. Background technique [0002] Hot water circulation pumps are widely used in the transportation and circulation of hot water or other organic exchange media in systems such as metallurgy, chemical industry, textile, large-scale building facilities and residential quarters, as well as central heating and technological processes. [0003] The internal water flow circulation of the current hot water circulation pump is often affected, which will greatly increase the loss of water flow and cause a waste of water resources. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a water-saving hot water circulation pump, which can ensure the circulating flow of water flow inside the pump body, reduce the loss of water flow through the pump body, and achieve the effect of water ...
