Description

Household electric jet pump diffusion pipe

Technical Field

The utility model relates to an injection pump technical field specifically is a household electric injection pump diffusion tube.

Background

The balance of a district heat supply network is always a technical problem to be solved urgently in the heat supply industry, and the adjustment work is very difficult due to the existence of hydraulic coupling. The jet pump has the function of water mixing, so that the flow of a pipe network can be reduced (on the premise of ensuring the sufficient flow of a heating system in a building), and the resistance of the heat supply network in a heating station and a district can be reduced. The large pressure difference is needed to be consumed at the nozzle, so that the resistance of the building or the entrance of the unit where the jet pump is installed is much larger than the pressure drop of the district heat network, the stability of the hydraulic system is greatly improved, the balance adjustment of the district heat network can be easily realized, the balance valve is mainly applied to the balance of the district heat network at present, the adjustment work is complex, the resistance consumed in the heating power station and the district heat network is very large because the flow of the heating power station and the district heat network is not reduced, the resource pressure difference at the entrance of the building or the unit is very small, the resistance of the balance valve working at different positions of the heat network is very large at the moment, the adjustment characteristic is very large, and the balance effect is not ideal. Some injection pumps adopting fixed nozzles of welded structures are applied to balance adjustment of a district heat supply network, the balance effect is good, and the power-saving effect is ideal. However, the nozzle cannot be replaced, the working condition cannot be adjusted, the large-area popularization and application are inconvenient, and particularly, the nozzle is not suitable for a community with a continuously changing survival rate.
