The electric pressure controller has the advantages that the disconnectable joint is convenient to be mounted, the pressure transducer can accurately display pressure variation of a water pump system via a LCD display panel, users can set up start pressure via the LCD display according to requirements, a control circuit utilizing a single chip microcomputer circuit can be added with other functions without changing the design of the circuit boards according to requirements of users, and the service life of the water pump system can be prolonged through temperature-controlled protection.
Description
Technical field
The utility model relates to and is used for the water pump water supply system electronic pressure controller of control automatically, especially relates to a kind of architecture advances of electronic pressure controller.
Background technology
The present electronic pressure controller that uses, being used for water pump water supply system controls automatically, start or switch off the pump by opening or closing water swivel, with spring starting pressure is set, magnet steel provides signal with the tongue tube electromagnetic induction to controller, but different starting pressures is provided with the spring that needs replacing different.LED light shows the pump working state, but can not show accurately that water pump system pressure changes, and can not freely be provided with starting pressure according to customer requirement.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide the accurate explicit user of a kind of energy with water state, can starting pressure be set freely, utilize magnet steel that Hall switch induction break-make is controlled water pump, added the electronic pressure controller of the overheating protection of water pump environment temperature, flexible joint.
The utility model is achieved through the following technical solutions: a kind of electronic pressure controller, comprise the box part and the flexible joint that are mutually permanently connected, bonnet, box part inside is provided with sensor circuit board component and main control circuit board component, its difference is, inductive circuit board is equipped with pressure transducer, Hall switch, thermistor, be positioned at into and establish the flow valve assembly near the water interface, in the flow valve assembly magnet steel is housed, Hall switch generation electromagnetic induction in this magnet steel and the sensor circuit board component, pressure transducer is embedded on the waterway pipe, provides pipeline water circuit system accurate pressure to change.Thermistor induced environment temperature variation is carried out overheating protection, and when environment temperature surpassed setting value, water pump system quit work, and flexible joint makes electronic pressure controller easier for installation.
The LCD display that the operation conditions of display system is arranged on the main control wiring board, electronic components such as single-chip microcomputer.
Hall switch generation electromagnetic induction produces electric signal in flow valve assembly magnet steel and the sensor circuit board component, the electric signal that provides with pressure transducer is input to single chip circuit jointly, the single chip circuit output signal is to LCD display and motor, and its output terminal is connected the startup of controlling water pump and closes with motor through relay.
The beneficial effects of the utility model are embodied in: flexible joint is convenient to be installed, and pressure transducer can accurately show that by the LCD display board water pump system pressure changes; The user can independently be provided with starting pressure by the LCD demonstration as required; Control circuit adopts single chip circuit, can set up other functions by customer requirement, and not need to change board design; The temperature control protection prolongs the water pump system life-span.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
