Description
Technical field
The present invention relates to a kind of water pump controller, especially a kind of water pump constant pressure frequency conversion controller.
Background technique
Town-dweller-rural-family, China water system controls water using mechanical pressure switches always from last century late nineteen eighties
Pump group is at water system.Since there is shortcomings for the system, water pump Fraquent start can be made, often burn pump motor.Extremely
Late nineteen nineties start commonly used electronic water pump automatic controller, since the controller can be according to detected water source shape
The data deactivations such as state, pipeline-used water amount and pipeline pressure variation and stopping water pump.It can substitute completely by pressure switch, water shortage guarantor
The legacy system that protection unit, pressurized tank, check-valves etc. are constituted.Completely isolated and high leakproofness the control of live part and pipeline
Case processed makes the controller have the incomparable safety of mechanical pressure switches, is used widely.
But, still there is the place of some shortcomings in the limitation of electronic water pump automatic controller function.Water pump is opened
Stop directly being controlled by relay, since motor is to directly initiate, starting current is equal to 4-7 times of rated current, in this way can be to electromechanics
Equipment and power supply grid cause serious impact, and the high current and vibration that when starting generates can to power supply line and water supply line
Certain damage is caused, it is totally unfavorable to the service life of equipment, pipeline, pump motor；It has a single function, and is only operable on and sets
Surely start pressure, can not change after pressure setting；And relay cut-offs period generation electric spark, greatly shortens the relay longevity
Life, lacks pump motor failure protection function.Furthermore once you start working, pump motor is just run with rated speed, and with volume
Water water supply is made, when water consumption reduction or when with water low ebb, ductwork pressure increases, the waste of electric energy and water resource is caused,
Also pipeline and system failure are be easy to cause.

Head body separate sealing diaphragm, set on intracorporal spring and the push rod on diaphragm, one end of the spring is resisted against
On head body, the other end is connected with the diaphragm.
In the middle when internal water flowing, in the presence of hydraulic pressure, diaphragm deformation squeezes spring, and push rod generates displacement, keeps head internal
Form the cavity of its buffer function.
There is the mounting portion for mounting head body, institute in above-mentioned water pump constant pressure frequency conversion controller, on the middle body
The bushing one for fixing above-mentioned diaphragm is equipped in the mounting portion stated, the head is equipped with the bushing for fixing diaphragm in vivo
Two, ram seat is additionally provided on the diaphragm, and above-mentioned push rod is fixed by screws in the ram seat.
In above-mentioned water pump constant pressure frequency conversion controller, the junction of the panel and middle body is fixed with scattered by bolt
Hot aluminium sheet and the heat dissipation copper billet for being located at middle body side set on heat-dissipating aluminium plate, the side that the heat-dissipating aluminium plate is located at panel is above-mentioned
Master board, the other side of the master board is equipped with circuit protection cover, O is equipped between the heat dissipation copper billet and middle body
Type circle one.
It is equipped in above-mentioned water pump constant pressure frequency conversion controller, in the check-valves and aggravates pin, and the check-valves
O-ring seal two is equipped between middle body.
In above-mentioned water pump constant pressure frequency conversion controller, the junction of the panel and middle body is equipped with sealing ring three.
Compared with prior art, this water pump constant pressure frequency conversion controller has the advantage that
The signal that master board is fed back according to check-valves and pressure sensor, the defeated of this controller is adjusted by logical operation in real time
Frequency out makes middle body inside water pressure keep identical as setting value, Lai Shixian constant pressure supplies so as to adjust the running speed of pump motor
Water function effectively extends the service life of this water pump constant pressure frequency conversion controller, and reasonable in design, and stability is good, close
Envelope property is good.
