The utility model provides a kind of changeable water supply controller for solving the problems of the technologies described above, this changeable water supply controller comprises for the motor that drives water pump, motor on off control branch road, electro connecting pressure gauge, lower limit control branch road and upper limit control branch road, lower limit control branch road comprises successively the starting contactor coil and a normally closed contact that stops contactor of serial connection, comprise a successively normally opened contact that stops contactor coil and starting contactor of serial connection on the upper limit control branch road, electro connecting pressure gauge includes a moving contact that moves with SEA LEVEL VARIATION and water level and reaches lower lower limit static contact and the water level that is electrically connected with moving contact in limited time and reach the upper limit static contact that is electrically connected with moving contact in limited time, the lower limit static contact of electro connecting pressure gauge and upper limit static contact are connected to respectively an end of power supply by lower limit control branch road and upper limit control branch road, the electro connecting pressure gauge moving contact is connected to the other end of power supply, also is provided with between described electro connecting pressure gauge moving contact and the lower limit static contact to make moving contact and lower limit static contact keep the maintenance branch road that is electrically connected before water level reaches the upper limit.
Described maintenance branch road is another normally opened contact that is arranged on the starting contactor between moving contact and the lower limit static contact.
Described motor on off control branch road comprises stop button, start button and the Electric Machine Control relay coil that is serially connected in successively both ends of power, and string and on this branch road starting contactor normally opened contact and stop another normally closed contact of contactor.
Described start button two ends also and be connected to the normally opened contact of Electric Machine Control relay.
The beneficial effects of the utility model are: changeable water supply controller of the present utility model comprises for the motor that drives water pump, motor on off control branch road, electro connecting pressure gauge, lower limit control branch road and upper limit control branch road, utilize lower limit control branch road and upper limit control branch road to finish the automatically switching of control of high-low water level, and when being separated, reduces contact spark phenomenon, improve electro connecting pressure gauge serviceable life, the utility model operating circuit is simple, reliable, can effectively control the start and stop of motor, thereby realize the reliable control of water level.
Description of drawings
Fig. 1 is the circuit structure diagram of the utility model water level controller.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in Figure 1, changeable water supply controller of the present utility model comprises for the motor 1M that drives water pump, motor on off control branch road, electro connecting pressure gauge, lower limit control branch road and upper limit control branch road, lower limit control branch road comprises successively the starting contactor coil 1K and the first normally closed contact that stops contactor 2K of serial connection, comprise successively first normally opened contact that stops contactor coil 2K and starting contactor 1K of serial connection on the upper limit control branch road, electro connecting pressure gauge includes a moving contact A who moves with SEA LEVEL VARIATION and water level and reaches lower lower limit static contact B and the water level that is electrically connected with moving contact A in limited time and reach the upper limit static contact C that is electrically connected with moving contact A in limited time, the moving contact A of electro connecting pressure gauge, lower limit static contact B and upper limit static contact C represent with different colours respectively, the lower limit static contact B of electro connecting pressure gauge and upper limit static contact C are connected to respectively an end of power supply by lower limit control branch road and upper limit control branch road, the electro connecting pressure gauge moving contact is connected to the other end of power supply, also be provided with between described electro connecting pressure gauge moving contact and the lower limit static contact and before water level reaches the upper limit, make moving contact and lower limit static contact keep the maintenance branch road that is electrically connected, keeping branch road is the second normally opened contact of starting contactor 1K, motor on off control branch road comprises the stop button K1 that is serially connected in successively both ends of power, start button K2 and Electric Machine Control relay coil 1KM, and string and on this branch road starting contactor 1K the 3rd normally opened contact and stop the second normally closed contact of contactor 2K, the start button two ends are also and be connected to the normally opened contact of Electric Machine Control relay.
Its course of work is as follows: electro connecting pressure gauge moving contact A and lower limit contact B connect when hydraulic pressure reduces, arrive contactor 1K through the 1K normally closed contact, the 1K coil gets electric adhesive, the auxiliary normally opened contact of 1K is connected, make 1K form self-hold circuit (at this moment leaving because of pressure rise electro connecting pressure gauge moving contact A and lower limit contact B), 1K gets electric band moving contact and meets main contactor 1KM, and main contactor contacting power drives motor is for feedwater.When pressure rise arrived set pressure, the moving contact A of electro connecting pressure gauge and upper limit contact C connected, and arrived the 2K coil through the 1K auxiliary contact, the 2K adhesive, and the auxiliary normally closed contact of 2K disconnects the 1KM releasing winding, and the main contacts disconnection stops the machine operation power supply.The purpose that the 2K coil seals in the 1K auxiliary contact be for 2K can reliable turn-off, to cause electric contact sometimes also can contact in higher-pressure region pressure shake unreliable because of tensimeter, so seal in auxiliary contact 1K, once 2K enters also dead electricity of dead electricity 1K, the 1K dead electricity, the auxiliary contact of 1K can reliably disconnect the loop of 2K.
The moving together contact of electro connecting pressure gauge in service repeatedly closed, disconnect repeatedly, and with " sparking " phenomenon, affect the reliability service of this changeable water supply controller, for this reason at the two ends of electro connecting pressure gauge break contact, the self-holding circuit that is in series by 1K moving together contact and 2K break contact in parallel, make self-holding circuit in case connect and with electro connecting pressure gauge break contact short circuit, to eliminate its repeatedly phenomenon of " sparking ".The moving together contact of a pair of 2K on the serial connection so that the 2KA once motion namely disconnects the self-holding circuit of 1K, makes the 1K involution in upper limit control loop, disconnects conversely upper limit control loop, and circuit is safe and reliable to operation like this.
