Description
Technical field
The utility model relates to a kind of water pump electronic pressure controller, refers to a kind of controller of the water pump electron pressure start-stop of being made up of flow switch, pressure switch, reset switch, trigger, relay especially.
Background technique
At present, in water pump control, all will use pressure and flow and come the startup of control of pump and stop, when pipeline pressure did not enough have flow, water pump just stopped automatically, can protect water pump like this, can reduce the loss that human error causes.
But because at work, traditional water pump electronic pressure controller is merely able to stopping of control of pump, that is to say, when manifold pressure not enough, when not having flow simultaneously, can stop pump operation automatically, but in pipeline, enough pressure is arranged, can not start water pump automatically, from new work, need cause certain inconvenience by manually starting.
Traditional water pump electronic pressure controller a period of time of can not delaying time starts water pump.
Summary of the invention
The utility model has the existing defective of technology at above-mentioned habit, and main purpose is to provide
A kind ofly can when the water pipe internal pressure does not have flow inadequately, stop pump operation automatically, when the water pump internal pressure is enough, can start the water pump electronic pressure controller of water pump automatically simultaneously
Another purpose of the utility model provides a kind of when the water pump internal pressure is enough, starts the adjustable water pump electronic pressure controller of delay time.
For realizing above-mentioned purpose, the following technological scheme of the utility model:
A kind of water pump electronic pressure controller, by flow switch, pressure switch, reset switch, trigger, relay is formed, be connected with the reset terminal of a counting chip at an end of pressure switch, the pulse input end of counting chip is connected with two concussion resistance and a capacitor, one end of two concussion resistance is connected on the counting chip, one end of the other end and capacitor connects together, the other end of capacitor also is connected on the counting chip, the output terminal of counting chip is connected to a base stage that drives triode by an output resistance, and the collector electrode of this driving triode is connected with an end of reset switch.
Simultaneously, also be connected with a toggle switch at the output terminal of described counting chip, the output terminal of toggle switch connects together, and is connected on the output resistance, and the other end of output resistance is connected on the base stage that drives triode.
Owing to adopted pressure detection circuit and transistor drive circuit, the utlity model has when siphon pressure is enough, start the function of water pump automatically
The utility model has plucking number sign switch, can adjust the plucking number sign switch position according to different time values, thereby the delay time of starting mode of pump can be adjusted.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
See also that technical solutions of the utility model are shown in Fig. 1 schematic diagram: a kind of water pump electronic pressure controller, by flow switch 2, pressure switch 3, reset switch 10, trigger 1, relay 12 is formed, be connected with the reset terminal of a counting chip 7 at an end of pressure switch 3, the pulse input end of counting chip is connected with concussion resistance first 4 concussion resistance second 6 and capacitors 5, one end of two concussion resistance is connected on the counting chip 7, one end of the other end and capacitor 5 connects together, the other end of capacitor 5 also is connected on the counting chip 7, the output terminal of counting chip 7 is connected to a base stage that drives triode 11 by an output resistance 9, and the collector electrode of this driving triode 11 is connected with an end of reset switch 10.
The output terminal of described counting chip 7 also is connected with a plucking number sign switch 8, and the output terminal of plucking number sign switch 8 connects together, and is connected on the output resistance 9, and the other end of output resistance 9 is connected on the base stage that drives triode 11.
When not having pressure in the water pipe, the water pump electronic pressure controller is under the effect of trigger 1, and the signal that control relay 12 outputs are closed stops water pump operation,
When in the water pipe when newly pressure being arranged, pressure switch 3 can be closed, enabling counting chip 7, the oscillator signal of counting chip 7 has concussion resistance and capacitor 5 to provide, and when timing time arrived, counting chip 7 can be exported a signal, be added on the driving triode 11 by output resistance, drive triode 11 by acting on the signal of reset switch 10,, start water pump from new starting relay 12.
Toggle switch 8 on the counting chip can be adjusted toggle switch 8 positions according to different time values, thereby the delay time of starting mode of pump can be adjusted.
The above, only be that this practicality imposes any restrictions technical scope of the present utility model, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
