Abstract
A pump power automatic control switch starts a contact switch at the preset minimum water level of a reservoir with gravity and flotage at the two sides of a pulley; and a pump starts pumping water; a broken contact switch is touched at the preset maximum water level of a reservoir, and a pump power is switched off for stopping pumping water, so the work cycle can ensure pumping water automatically.
Description
Technical field:
The utility model relates to a kind of electric control switch, especially relates to the pump power gauge tap that cistern draws water.
Background technology
At present, the switch that draws water before the known public affairs is by artificial directly control, has only not had water and just can realize manual control opening and closing then.So do not have water when often being badly in need of water, very inconvenient, and, cause waste easily owing to be difficult to hold the time of closing.
Summary of the invention
The utility model partly is made up of master control part and low tension switch
Of the present utility model low press off produce part by a pulley, weight A, weight B,, steady arm A, steady arm B, start contact switch (being off-state when not stressing), opening contact switch (being closure state when not stressing), rope and a float and form.Weight A and weight B hang on the pulley both sides respectively with rope, and float and weight B are installed together, and the floatage energy of float bears the gravity of weight B, always bubble through the water column, weight A, weight B can move up and down with water level.Steady arm A is installed on the rope between weight A and the pulley, but its position on rope of regulated at will, with control water level.Between steady arm A and pulley, install and start contact switch.The steady arm B of adjustable position is installed on the rope between float and the pulley, the installation opening contact switch of steady arm B and pulley, it is hermetic starting contact switch and opening contact switch, prevents the invasion of aqueous vapor, damages element.
Weight A gravity is that GA weight B gravity is that GB float buoyancy is that the floating startup of F contact switch elastic force is that FA opening contact switch elastic force is FB
The stressed relation of its each parts is as follows:
Water level is between peak level and high low-water level
GA=GB+F is floating
When water level is positioned at lowest water level
GB-+F floats+GA 〉=FA
When water level is positioned at peak level
(GB+F is floating)+GA 〉=FB
When water level was positioned at minimum point, making a concerted effort of weight A, weight B and float made steady arm A produce pulling force upwards and overcomes startup contact switch elastic force, makes to start the contact switch closure.When water level was positioned at peak, making a concerted effort of weight A, weight B and float made steady arm B produce pulling force upwards and overcomes the opening contact switch, and the opening contact switch is disconnected.
A master control of the present utility model partly transformer, two diodes, an electric capacity, a relay is formed.Transformation be input as 220V, the domestic power supply of 50HZ is output as the low-voltage AC of 36V-6V, after both positive and negative polarity was respectively connected a diode, electric capacity in parallel was rectified into the galvanic current source.Relay is that 220V can be born, the above electrical appliance of 500W (water pump) in double-contact (or multiconductor) and one of them contact.Power cathode after the rectification is connected on an end of relay coil, and the low-pressure contact of relay is connected with the opening contact switch, and this series circuit is with starting the other end that the contact switch parallel connection is connected on relay coil, and the relay high-voltage contact is connected with water pump.
When water level is positioned at minimum point, start the contact switch closure, relay contact closure, water pump are opened this work, when water level rises, start contact switch and disconnect, and at this moment, the working current of relay is by the circuit supply of opening contact switch and the series connection of relay low-pressure contact.When water level was raised to peak, the opening contact switch disconnected, and relay quits work, and water pump quits work.Work so circularly.
Description of drawings
