Description

Automatic pumping controller

The utility model belongs to a kind of electronic automatic control device, is specially adapted to the water supply automatic controller of water tank.

Present normally float-ball type and electric pole type of the automatic pumping system controller of China's urban building, its weak point is that reliability is relatively poor, cost is higher, as Chinese patent literature CN2117627 with CN10514337 is disclosed just belongs to this type of.The circuit of this class control device will be guided to machine room from high level cistern, electric wire is exposed to outdoor, electronic control component is more, the element environment for use that wherein has is very abominable, thus this just brought complex structure, that cost is higher, functional reliability is poor, electric motor starting is too frequent, install and use inconvenience, start-up time is irregular etc. is unfavorable.

The purpose of this utility model provides a kind of full automatic controller, and it will not be connected on the open air by control line, and employed components and parts are less, and are simple in structure, and cost is low, reliable operation, and installation and easy to use, without the personal management, extensively practical, water supply coverage is big.

The utility model is achieved in that the crucial control assembly of control device is electro connecting pressure gauge and leve automatic controller, the union of electro connecting pressure gauge is connected on the outlet pipe of water pump, the flexible pipe of hydraulic pressure automatic controller inserts in the reservoir lower curtate, in the current path of electro connecting pressure gauge and leve automatic controller, insert relay, on the phase line of pump motor, be in series with the contact of being controlled by relay.Also be in series with ripe relay on the phase line of pump motor, the contact is arranged on the contact that is in series with a time time switch and thermal relay on the relay current path of motor phase line, also is parallel with a self holding contact at the power line two ends of described time time switch.When electro connecting pressure gauge and leve automatic controller are installed; can be in pump house directly union and flexible pipe be connected at the bottom of pumping line and the reservoir respectively; need not again electric wire be dragged to high level cistern; just can regularly draw water reliably; wait completely back or just can autostop during the reservoir lack of water of all water tanks; thereby reach energy-saving and water-saving, the protection pumping system increases the service life.

Below, the of the present utility model several specific embodiments according to Figure of description provides are further described its detailed structure.

Fig. 1 is a scheme of installation of the present utility model;

Electrical schematic diagram when Fig. 2 uses heavy-duty motor for the utility model;

Electrical schematic diagram when Fig. 3 uses low-power machine for the utility model;

Electrical schematic diagram when Fig. 4 uses monophase machine for the utility model;

Each label is represented successively among the figure: high level cistern 1, float valve 2, control cabinet 3, electro connecting pressure gauge 4 or P, leve automatic controller 5 or Y, pump motor 6 or d, water inlet pipe 7, reservoir 8, outlet pipe 9, graduating valve 10, time time switch S, auxiliary reclay J, AC relay C, thermal relay R, indicator lamp D ₁～D ₃, press button AN ₁, AN ₂

Referring to each figure, the union of electro connecting pressure gauge 4 is connected on the pumping line 9, the flexible pipe of leve automatic controller 5 is inserted into the bottom (see figure 1) of reservoir 8, be in series with relay in the current path of electro connecting pressure gauge P and leve automatic controller Y and (see Fig. 2～Fig. 4), both parallel connections were connected with auxiliary reclay J again when power of motor was big, and then the break-make of AC relay C in the control circuit; Power of motor is directly connected with AC relay C than hour both series connection again and is got final product, and pump motor d is in series with the contact C that controlled by AC relay C ₁～C ₃As long as electro connecting pressure gauge P or leve automatic controller Y begin action, just can cut off the electric current of AC relay, thereby pump motor is quit work.

In order to prevent that the on-stream heating of motor d from burning out, the thermal relay R that should connect on its phase line, its contact R ₁Be connected on the path of AC relay C, when some adstante febre of motor, thermal relay R makes its constant close contact R ₁Disconnect, AC relay C makes contact C ₁～C ₃Disconnect, thereby motor d quits work.Each opening time of setting of time time switch S is 1 minute, and the electrical current after 1 minute is provided by self holding contact C '.The press button AN in parallel at C ' two ends ₁, and when time time switch S cancelled, this controller just became semi-automatic pumping controller, and its cost is lower, will manually start when only just drawing water, and all the other functions are identical with full-automatic pumping controller.Press button AN ₂At this is to be used for hesitation.

Referring to Fig. 2, when pump motor power is big (as greater than 3KW), electro connecting pressure gauge P parallel with one another and leve automatic controller Y and an auxiliary reclay J are in series and constitute a current path of control circuit, the contact J of this auxiliary reclay J ₁, J ₂, time time switch S, thermal relay contact R ₁Series connection constitutes another current path of control circuit with AC relay C, and AC relay C is controlling the contact C that motor d phase line is connected again ₁～C ₃When pump motor power hour (as less than 3W), the contact R of electro connecting pressure gauge P, leve automatic controller Y, time time switch S, AC relay C and thermal relay ₁The formation control circuit that can directly be cascaded mutually makes designs simplification, further reduces the cost of controller.

Pumping line 9 is to adorning a graduating valve 10 between the union of electro connecting pressure gauge P, it makes electro connecting pressure gauge P dynamic stability during electric motor starting, can exempt hydraulic pressure in the outlet pipe 9 moment and improve the misoperation that causes electro connecting pressure gauge P or its machine components and rock for a long time and influence application life.The phase line of pump motor d is parallel with indicator lamp D ₁～D ₃, can demonstrate the whether phase failure of motor.Each components and parts preferably uses the product of commercially available stable performance in this device, and electro connecting pressure gauge P can adopt domestic standard YX series of products, is decided by the lift of water pump during installation; Time time switch S can produce ES series programmable time controller with sharp Electronic Arts Inc. of Beijing Xinhua, and this product can be set switch arbitrarily No. 6 times in 24 hours, used it can make time of pumping regular, and can be set in desirable time of pumping; Leve automatic controller Y can select for use Jian County, Zhejiang leve automatic controller factory to produce the ESK series of products, is decided by the depth of reservoir during use.

From technique scheme of the present utility model, its structure is very simple, the components and parts that use seldom, cost is lower, and installation and easy to use need not be guided to high level cistern with electric wire, the components and parts that adopt are mature and stable, therefore the stable performance of entire controller, reliable operation can be protected pumping system; It is received electro connecting pressure gauge on the outlet pipe dexterously, can reach wait all water tanks full after, the pipe internal pressure is raised to predetermined value, the purpose that just stops pumping.
