Description
Technical field
The utility model relates to a kind of compressor pressure unit.
Background technology
Pressure unit is a kind of sensor the most conventional in industrial practice, and the fluid pressure signal detected is sent to computing machine and carries out Stress control or monitoring by it.The pressure signal that pressure unit detects is continuous print, therefore at random can arrange pressure by automatically controlled part, and the senior operation realizing compressor controls, and makes compressor operating more steady, thus extends the serviceable life of compressor.
The performance of pressure unit depends primarily on pressure-active element and amplifying circuit etc., traditional compressor pressure unit adopts ceramic core body as sensitive element mostly, and the Property comparison of pottery itself is fragile, in use once run into overload, be easy to destroy even explosion, thus transmitter is scrapped.The sealing means that traditional compressor pressure unit adopts end face to compress in installation, this mode must calculate the decrement of O type circle in advance, causes the requirement to part is produced to improve, is unsuitable for batch production.
Utility model content
The technical problems to be solved in the utility model be in order to overcome compressor pressure unit sensitivity traditional in prior art lower, run into overload easy explosion and the low inferior defect of production efficiency, provide a kind of compressor pressure unit.
The utility model solves above-mentioned technical matters by following technical proposals:
A kind of compressor pressure unit, comprise a pressure inlet, an O type circle, a back-up ring, a pressure transducer and an amplifying circuit, its feature is, described compressor pressure unit also comprises a compensating plate and a shell; Described pressure transducer comprises an elastic body and two resistance silicon, and described resistance silicon is sintered in described elastomeric surface by micro-molten technology; Described O type circle is used for described elastic body radial seal in described pressure inlet; Described back-up ring is positioned at described pressure inlet, and described back-up ring is used for fixing described elastic body; Described compensating plate is adhered on described pressure inlet; Described amplifying circuit is positioned at described shell; Described compensating plate is electrically connected with the resistance silicon of described pressure transducer, described amplifying circuit respectively; Described shell is placed on outside described pressure inlet, and described shell and described pressure inlet machinery are held tightly.
Preferably, described compressor pressure unit also comprises one or three core plug-in units, and described three core plug-in units and described outer casing screw connect, described three core plug-in units are electrically connected with described amplifying circuit, described three core plug-in units are metal three core plug-in unit, not only increase reliability, and outward appearance are more attractive in appearance.
Preferably, in order to meet the needs producing assembling better, described back-up ring is hole elastic spring.
Positive progressive effect of the present utility model is:
1, the utility model has tied resistance silicon by micro-fusing on elastic body, not only increases the sensitivity of sensor, and farthest improves limit anti-overload ability and the anti-burst ability of pressure unit.
2, compressor pressure unit of the present utility model adopts the radial seal of O type circle, easy to assembly and the used time is less; Adopt machinery to hold shell tightly, improve production efficiency, be applicable to producing in enormous quantities.
Accompanying drawing explanation
Fig. 1 is the cut-open view of the compressor pressure unit of the utility model one embodiment.
Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
As shown in Figure 1, compressor pressure unit of the present utility model comprises pressure inlet 1, O type circle 2, back-up ring 3, pressure transducer 4, compensating plate 5, amplifying circuit 6, shell 7 and a metal three core plug-in unit 8.Pressure transducer 4 comprises an elastic body 41 and two resistance silicon 42, and resistance silicon 42 is sintered in the surface of elastic body 41 by micro-molten technology.The sensitivity when 5V powers of traditional ceramic pressure sensor is 10mV, can bear 1.5 times of full scale loads, and when bearing 2 times of loads, pressure unit can break.Pressure transducer described in the utility model adopts micro-molten technology, and when 5V powers, sensitivity can reach 50mV.In addition, owing to have employed micro-molten technology, use the anti-overload ability of the compressor of pressure unit of the present utility model can reach 2.5 times, anti-burst ability can reach more than 5 times.Therefore, compared with existing conventional pressure transmitter, the performance of compressor pressure unit of the present utility model is greatly improved.
O type circle 2 is inserted on elastic body 41, and adopt the mode of radial seal to be installed in the endoporus of pressure inlet 1, this mode is very convenient in assembling, and the used time is less.Hole elastic spring 3 is placed in the hole of pressure inlet 1, and elastic body 41 is located fixing by passing hole elastic spring 3.Compensating plate 5 is adhered on pressure inlet 1 by silica gel, and resistance silicon 42 and compensating plate 5 are connected to form sensor loop by aluminium wire.Amplifying circuit 6 is fixed on compensating plate 5 by contact pin soldering, and wherein, compensating plate 5 also serves the effect of temperature compensation.Amplifying circuit 6 is positioned at shell 7, and does not contact with shell 7.Can debug after circuit installation, after having debugged, by the wire of amplifying circuit 6 and the soldering of metal three core plug-in unit 8, metal three core plug-in unit 8 and shell 7 spiral marking connection, fixed by screw thread glue, then shell 7 is placed on pressure inlet 1, complete the integral installation of pressure unit.The mode that its housing 7 adopts machinery to hold tightly with pressure inlet 1, can enhance productivity, be applicable to large batch of production.
Compressor pressure unit of the present utility model is the current signal that pressure parameter pressure transducer being experienced gas changes 4 ~ 20mA into, the size of current signal and pressure is proportional, and the electric current that is pressure unit exports increases with the increase of gaseous tension.Compressor pressure unit is a for the pressure monitoring instrument in air compressor device, and the current signal that therefore can export according to pressure unit controls the operation of air compressor.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
