Description
Technical field
The present invention relates to a kind of booster pump more particularly to a kind of automatic pressure pumps of household.
Background technique
In daily life, it is inadequate, poor with the small bring experience of water flow usually to encounter hydraulic pressure when with water for we
The problem of, or even the problems such as the relevant device that occurs in pipeline can not work normally.For example, when using gas heater, it can
It can encounter that water flow is too small, can not light a fire, Automatic-boosting is carried out to pipe-line system using automatic pressure pump at this time and is necessary.
It (either and is pumped currently, automatic pressure pump on the market generallys use flow switch as the device of traffic aware
It is that body is integrally installed or external on the pump housing), control principle is, when water flow flows through, the tongue piece in runner occurs inclined
Turn, drive the magnet at top close to external tongue tube, be closed the tongue tube outside runner, automatic pressure pump is opened, to pipeline
Pressurization；When non-water flow in runner, tongue piece resets under the action of returning spring, and magnet is disconnected far from tongue tube, tongue tube, from
Dynamic pressurization stops working.
This flow switch have it is cheap, control simple advantage, be particularly suitable for the conventional asynchronous in no control panel
It is used on motor-driven booster pump, still, this flow switch has starting flow (minimum flow requires to be 3L/min) partially
Big problem, however, 3L/min is often not achieved in the water flow in pipeline when the hydraulic pressure deficiency of subscriber household pipeline, it can not
Make Automatic-boosting pump startup, the purpose being pressurized to the water flow of pipeline is not achieved.
Summary of the invention
A kind of automatic pressure pump is provided it is an object of the invention to solve the above problem of the existing technology, in the pump housing
