Problems solved by technology

[0004] This kind of flow switch has the advantages of cheap price and simple control, and is especially suitable for use on booster pumps driven by traditional asynchronous motors without a control board. Big problem, however, when the water pressure of the user's home pipeline is insufficient, the water flow in the pipeline often does not reach 3L / min, and the automatic booster pump cannot be activated, and the water flow in the pipeline cannot be boosted. the goal of

Embodiment

[0028] Example: such as Figure 1-5 As shown, the automatic booster pump has a motor 2 with a control board 21, and the casing 23 of the motor and the pump body 1 have corresponding flanges, which are fixedly connected by screws. The pump body is provided with an impeller 3 and the motor The rotor assembly 4 arranged inside is fixedly connected as a whole, and rotates around the fixed shaft 5 to achieve the effect of water flow boosting. The stator assembly 22 set on the periphery of the rotor assembly, and the control board 21 are covered by plastic molding compound (BMC) to form a whole, and the casing 23 of the motor is integrally formed by using the plastic packaging compound, and the rotor assembly and the stator assembly are separated by a shielding sleeve 6 isolation to ensure that the transported medium in the shielding sleeve does not leak.

[0029] Such as Figure 2-4 As shown, the pump body 1 is made of copper, and the water inlet pipe section or the water outlet ...

Abstract

The invention relates to an automatic booster pump for home use, and solves the problem that the automatic booster pump cannot be started due to water flow is too small in the prior art. According to the technical scheme, the automatic booster pump is characterized in that a turbine type hall flow sensor is arranged at a water inlet pipe section or a water outlet pipe section of a pump body; the turbine type hall flow sensor comprises a bottom shell, a middle cover, a turbine, a magnetic piece and a hall sensor, wherein the bottom shell is integrally formed with the pump body; the middle cover is in sealing fit with the bottom shell; the turbine is rotatably arranged between the bottom shell and the middle cover; the magnetic piece is arranged at the end, close to the middle cover, of the turbine; and the hall sensor is arranged on the middle cover and corresponds to the magnetic piece and is in signal connection with a control module. The automatic booster pump has the advantages of being high in water flow detection precision and solving the problem of small flow ( the water flow is less than or equal to 3L/min and is greater than or equal to 1L/min), the problem that the water pump cannot automatically pressurize is solved, and when the water flow is greater than or equal to 1L/min, and the automatic booster pump can work and pressurize a pipeline.

Description

technical field [0001] The invention relates to a booster pump, in particular to a household automatic booster pump. Background technique [0002] In daily life, when we use water, we often encounter problems such as insufficient water pressure, poor experience caused by small water flow, and even problems such as the failure of related equipment in the pipeline. For example, when using a gas water heater, the water flow may be too small to ignite. At this time, it is necessary to use an automatic booster pump to automatically boost the pipeline system. [0003] At present, the automatic booster pumps on the market generally use a flow switch as a flow sensing device (whether it is installed integrally with the pump body or connected externally to the pump body). The tongue is deflected, driving the top magnet close to the external reed switch, closing the reed switch outside the flow channel, and the automatic booster pump is turned on to pressurize the pipeline; Reset un...
