Aluminium electroloysis is generally carry out in special electrolytic tank, and electrolytic tank is a kind of electrochemical reactor needing direct current energy, therefore, needs to carry out rectification before civil power leads to electrolytic tank, and the protection ratio of rectifier cabinet is indispensable.In view of rectifier cabinet cooling system adopts pure internal water cooling mode; the safe operation of stability to rectifier cabinet that inner cold water runs is most important; the detection of internal cold water pressure also should be applied in the important protection of rectifier cabinet; when hydraulic pressure is low to moderate certain value; rectifier cabinet pulse will be blocked automatically; forced commutation cabinet output current reduces to zero, avoids rectifier cabinet to cross cause thermal damage.
The Rectification Power Factor rectifier cabinet water pressure gauge design of current aluminium manufacturer adopts plain edition electro connecting pressure gauge; range is 0 ~ 0.6MPa; operating voltage (the highest): 380V; contactless power 30VA; observe from on-the-spot actual operating state; contact capacity is not enough, electric contact is shaken, earthquake-proof function is poor; the requirement of detection, protection can not be met; repeatedly occur that tensimeter damages malfunction abnormal; the safe operation of serious threat Rectification Power Factor; in order to realize, equipment is reliable, safe operation, in the urgent need to the novel shockproof electrical contact manometer of one.
Summary of the invention
The purpose of this utility model is to provide a kind of novel shock-proof pressure gauge, to improve, to strengthen reliability and the accuracy of tensimeter detection.
Based on above-mentioned purpose, the utility model takes following technical scheme: a kind of novel shock-proof pressure gauge, comprise watchcase, bourdon tube, cogwheel gearing, terminal box, scale, pointer, cloche, described watchcase inside is provided with bourdon tube and cogwheel gearing, the top of watchcase is provided with oil hole, oil hole rubber seal, the terminating wire hole place of described watchcase outer end is equipped with terminal box, the bottom of watchcase is equipped with the main body joint be connected with bourdon tube, described scale is provided with pointer by pointer central shaft, described cloche is dome shape, to be fastened on watchcase and to be sealed by O-ring seal.
Further, described terminal box comprises the first connecting portion and the second connecting portion, and one end of the first connecting portion is the cylindric of through hole in band, match with wiring hole, the other end is engaged by screw thread mutually with the second connecting portion, and the second connecting portion is hollow form, is used for drawing wire.
Further, in described watchcase, be filled with silicone oil or glycerine, be used for reducing the impact shaking and bring.
Compared with prior art, the beneficial effects of the utility model are: structure is simple, easy to assembly, directly terminal box are embedded, can complete light docking, and unpacking welding when avoiding existing terminal box to access or export, ensure that circuit does not fracture, Received signal strength is stablized.

Embodiment:
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As Fig. 1, shown in Fig. 2, a kind of novel shock-proof pressure gauge, comprise watchcase 1, bourdon tube 2, cogwheel gearing 3, terminal box 4, scale 5, pointer 6, cloche 7, the inside of described watchcase 1 is provided with bourdon tube 2 and cogwheel gearing 3, the top of watchcase 1 is provided with oil hole 8, oil hole 8 rubber plug 9 seals, the terminating wire hole place of described watchcase 1 outer end is equipped with terminal box 4, the bottom of watchcase 1 is equipped with the main body joint 10 be connected with bourdon tube 2, described scale 5 is provided with pointer 6 by pointer central shaft, described cloche 7 is in dome shape, to be fastened on watchcase 1 and to be sealed by O-ring seal 11.
Further, one end that described terminal box 4 comprises the first connecting portion 41 and the second connecting portion 42, first connecting portion 41 is the cylindric of through hole in band, match with wiring hole, the other end is engaged by screw thread mutually with the second connecting portion 42, and the second connecting portion 42 is hollow form, is used for drawing wire.
Further, in described watchcase 1, be filled with silicone oil or glycerine, be used for reducing the impact shaking and bring.
The utility model, reality is novel shockproof electrical contact manometer, be applicable to the pressure of the medium such as liquid, gas of noncrystalline, the non-condensable measured without explosion danger, and send signal when pressure reaches predetermined value and connect control circuit, reach and automatically control and the object of warning.
In the present embodiment, be applied to the detection of rectifier cabinet inner cold water pressure, the technical characterstic needing summation device to run from actual motion is considered, change former design proposal, Rectification Power Factor rectifier cabinet water pressure gauge adopts the New Magnetic Field Controlled after improving to help formula, oil-filling type shockproof electrical contact manometer, range: 0 ~ 0.6MPa, operating voltage (the highest): 380VAC, 220VDC, contactless power 50VA, more former design pressure table contact rating improves 20VA, easy to use, solve contact capacity deficiency at one stroke, electric contact is shaken, a difficult problem for earthquake-proof function difference, thus guarantee the safety of Rectification Power Factor, stable operation.
Specific works principle of the present utility model is: based on the bourdon tube in measuring system under the pressure effect of measured medium, bourdon tube end is forced to produce corresponding elastic deformation one displacement, amplification is given through the transmission of gear drive by pull bar, indicated on scale by by measured value by the instruction (together with contact) on fixed gear, simultaneously, when it to contact the instantaneous of (dynamic circuit breaker or dynamic circuit connector) with the contact (upper limit or lower limit) on setting pointer, the circuit in control system is caused to be disconnected or connect, to reach the object automatically controlling and transmit warning.
