Description

The air bubble type water gauge that the air pump normal pressure starts
Technical field
The utility model belongs to field of sensor measurement, relates in particular to the air bubble type water gauge that a kind of air pump normal pressure starts.
Background technology
Air bubble type water level is in respect of two kinds, and a kind of is to use compressed gas cylinder as the water-level gauge of core drive device, and another kind is to adopt reciprocating air pump as the water-level gauge of core drive device.Air bubble type water gauge needs online long-play, and when water level changed, air pump just may need to move inflated pressurization.Existing air bubble type water gauge take reciprocating air pump as propulsion system, it is almost equal that air pump has been beaten after gas the pressure in endotracheal pressure and air chamber, to start with the form that band carries when air pump need to start again, cause difficulty in starting, starting current is also therefore different and different with loading condition.As everyone knows, band carries and excessively may cause the air pump motor stall or the situation such as burn out occurs, and the air pump band carries the serviceable life that startup has not only reduced motor, also cause system to power supply require highly, increased production cost.
The utility model content
The purpose of this utility model is as overcoming the defective of prior art, and the air bubble type water gauge that provides a kind of air pump to start under the environment of normal pressure.
For achieving the above object, the utility model by the following technical solutions: the air bubble type water gauge that a kind of air pump normal pressure starts comprises an air pump, an air chamber, a measuring cup, one first pressure transducer, a control device and some tracheaes; Described the first pressure transducer is located in air chamber, the gas outlet of described air chamber is connected with measuring cup by tracheae, the air intake opening of described air chamber is connected with a three-way connection by tracheae, one interface of described three-way connection is connected with air pump by tracheae, another interface of this three-way connection is connected with a blowdown valve, described blowdown valve is provided with one second pressure transducer, and described blowdown valve, air pump and air chamber are electrically connected with described control device respectively.
Specifically, described pressure-release valve is solenoid valve.
Specifically, described control device is provided with pressure signal processing module, data acquisition and processing (DAP) module, power module, input/output module and display module.
Specifically, described the first pressure transducer and the second pressure transducer are the Honeywell pressure transducer.
Furtherly, the air intake of described air pump is provided with a screen pack.
The utility model is set up a pressure-release valve on the tracheae that connects air pump and air chamber, air pump to air chamber inflate complete after, with endotracheal pressure and ambient pressure balance, realize normal pressure startup for air pump next time starts by pressure-release valve.
Compared with prior art, the beneficial effects of the utility model are: the utility model has been set up the function of automatically unloading, and air pump can be started under normal pressure, avoids the air pump band to carry startup, reduces starting current, reduces power consumption; Simultaneously, effectively protect the motor of power circuit and air pump, extended the serviceable life of equipment, improved the stability of system's operation.
Description of drawings
Fig. 1 is the structural representation of the air bubble type water gauge of the utility model air pump normal pressure startup.
Embodiment
In order to more fully understand technology contents of the present utility model, below in conjunction with specific embodiment, the technical solution of the utility model is further introduced and explanation.
Embodiment
Be illustrated in figure 1 as structural representation of the present utility model, the air bubble type water gauge that a kind of air pump normal pressure starts comprises an air pump 2, an air chamber 5, a measuring cup 6, a control device 10, a three-way connection 3, a blowdown valve 9, one first pressure transducer 7, one second pressure transducer 8 and some tracheaes 4; The first pressure transducer 7 is located in air chamber 5, and this first pressure transducer 7 is the Honeywell pressure transducer, and the gas outlet 51 of air chamber 5 is connected with measuring cup 6 by tracheae 4; The air intake opening 51 of air chamber 5 is connected with a three-way connection 3 by tracheae 4, one interface of three-way connection 3 is connected with air pump 2 by tracheae, air intake opening 51 places of air pump 2 are provided with a screen pack 1, another interface of this three-way connection 3 is connected with a blowdown valve 9, blowdown valve 9 is solenoid valve, solenoid valve is provided with one second pressure transducer 8, and this second pressure transducer 8 is the Honeywell pressure transducer; Control device 10 is provided with pressure signal processing module, data acquisition and processing (DAP) module, power module, input/output module and display module, and control device 10 is electrically connected with solenoid valve 9, air pump 2 and air chamber 5 respectively.
during operation the utility model, measuring cup 6 is placed under water, solenoid valve 9 is in closed condition, booster air pump 2 is inflated to air chamber 5, gas in air chamber 5 divides two-way to carry to the first pressure transducer 7 and measuring cup 6 respectively, the first pressure transducer 7 produces data output because of the effect that is under pressure, the water that connects simultaneously in the tracheae 4 of measuring cup 6 is slowly discharged, when the gas in tracheae 4 reaches mobile equilibrium, air pump 2 stops inflating, the pressure that this moment, measuring cup 6 under water bore is delivered to through tracheae 4 pressure that makes both on the first pressure transducer 7 and equates, processing by control device 10 can record water level value, after air pump 2 stops inflating, control device 10 judges that according to the data of the second pressure transducer 8 output whether the force value at solenoid valve 9 places is greater than setting value, open pressure release if control solenoid valve 9 greater than setting value, complete pressure release rear electromagnetic valve 9 and recover closed conditions, thereby readyly realize air pump of the present utility model in the situation that normal pressure starts for next air pump 2 starts.
