Description

Technical Field

[0001] The invention relates to an automatic booster pump, in particular to an automatic booster pump with an iron pump body. Background Art

[0002] At present, there are various structural forms of household automatic booster pumps, which are used in different working conditions and market segments, but the pump body is usually made of only two materials: copper and plastic.

[0003] The copper pump body is cast and can be processed and manufactured according to the best hydraulic conditions to produce a high-efficiency, energy-saving and power-saving automatic booster pump. However, the high cost of the copper pump body limits the user market of the water pump, which is usually limited to the high-end user market.

[0004] Plastic pump bodies, due to the limitation of core pulling in injection molds, have great restrictions on the pump volute, which has a great impact on the efficiency of the automatic booster pump.

[0005] For the low-end user market, there is still a lack of efficient and energy-saving automatic booster pumps. Summary of the invention

The pump body is made of iron material, and the guide body and the magnet are arranged in the pipe section of the pump body. A flow switch assembly port is started on the pipe section. The sensing end of the induction control mechanism extends through the assembly port and is connected with the inner cavity of the pipe section. It can sense the change of the magnetic lines of force of the magnet and solve the magnetic field shielding effect of the iron pump body on the magnet. This is beneficial to reducing the cost of the water pump and achieving high efficiency and energy saving, providing a good choice for the low-end user market.
