Abstract
The utility model provides a vibration-resistant temperature measurement element applied to rotation machinery. The vibration-resistant temperature measurement element comprises a forward spring, a guide tube, a detachable protective cover, an element fixation flange, a reverse stress spring and a temperature measurement element. The guide tube is provided with an inner through hole, one end of the guide tub is provided with the detachable protective cover, the end portion of the detachable protective cover is provided with the forward spring; the temperature measurement element is arranged in the detachable protective cover, the connecting lead of the temperature measurement element passes through the guide tube; the other end of the guide tub is provided with the element fixation flange, and the element fixation flange is provided with the reverse stress spring. According to the utility model, the temperature measurement element can be detached, and maintenance is facilitated. At the same time, the vibration-resistant temperature measurement element can be integrally dismounted, thus replacement of any parts can be facilitated.
Description
Technical field
The utility model relates to field of mechanical technique, particularly relates to a kind of Anti-seismic temperature element being applied on rotary machine.
Background technology
Sensitive element refers to the element that can experience delicately measured variable and make response, is can the measured part of direct feeling in sensor.In commercial production, contact temperature-measuring sensitive element mainly contains thermal resistance and thermopair.The temperature element great majority that at present power plant is used are contact, and anti-seismic performance is poor, easily cause the measurement data even mistake that fluctuates.Once lose, to the real-time monitoring of measurand, just easily cause the large-scale favourable turn cannot reliability service, directly cause main equipment to exert oneself and decline and be unfavorable for equipment stable operation.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of can superior performance and anti-seismic performance good be applied to the Anti-seismic temperature element on rotary machine.
For solving the problems of the technologies described above, the utility model embodiment provides a kind of Anti-seismic temperature element being applied on rotary machine, comprises forward spring, guide pipe, detachable protective cover, element mounting flange, reversed stress spring, temperature element; Wherein said guide pipe has inner via hole, and one end of described guide pipe is provided with detachable protective cover, and described detachable protective cover end is provided with forward spring; Described temperature element is arranged in described detachable protective cover, and the connection wire of described temperature element is through described guide pipe; The other end of described guide pipe is provided with element mounting flange, and described element mounting flange is provided with reversed stress spring.
As technique scheme preferably, described detachable protective cover one end connects guide pipe, the other end is provided with connecting portion, described forward spring housing is connected on described connecting portion.
As technique scheme preferably, the external diameter of described connecting portion is less than described guide pipe external diameter.
As technique scheme preferably, on described element mounting flange, be also provided with set bolt, described reversed stress spring housing is connected on described set bolt.
As technique scheme preferably, described temperature element is end face thermal resistance or end face thermopair.
The beneficial effect of technique scheme of the present utility model is as follows:
The Anti-seismic temperature element being applied on rotary machine of the present utility model, has realized temperature element detachable, easy access.Integral body can both be dismantled simultaneously, is convenient to carry out any part replacement.The utlity model has the features such as high temperature resistant, antidetonation simultaneously, be conducive to guarantee the reliable and measurement data of measuring point accurately, can increase the service life, there is maintenance little, cost-saving.The utility model applied range, fixed form are flexible.By different fixed forms, can be installed in various kinds of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation that is applied to the Anti-seismic temperature element on rotary machine of the utility model embodiment;
Fig. 2 is the exploded view of Fig. 1.
Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1 and Figure 2, the utility model proposes a kind of Anti-seismic temperature element being applied on rotary machine, comprise forward spring 1, guide pipe 3, detachable protective cover 2, element mounting flange 4, reversed stress spring 5, temperature element; Wherein said guide pipe 3 has inner via hole, and one end of described guide pipe is provided with detachable protective cover 2, and described detachable protective cover 2 ends are provided with forward spring 1; Described temperature element is arranged in described detachable protective cover 2, and the connection wire of described temperature element is through described guide pipe 3; The other end of described guide pipe 3 is provided with element mounting flange 4, and described element mounting flange 4 is provided with reversed stress spring 5.As shown in Figure 1, described detachable protective cover 2 one end connect guide pipe 3, and the other end is provided with connecting portion, and described forward spring housing 1 is connected on described connecting portion.The external diameter of described connecting portion is less than described guide pipe external diameter.Wherein, on described element mounting flange 4, be also provided with set bolt 6, described reversed stress spring 5 is socketed on described set bolt 6.Wherein, described temperature element is end face thermal resistance or end face thermopair.
The functions such as that the utility model can be realized is high temperature resistant, antidetonation are integrated, and dismountable structure is conducive to element prophylactic repair, between guide pipe and probe protective cover, adopt and are threaded, and are convenient to check the element damaged condition of popping one's head in.Wherein temperature element (thermal resistance or thermopair) is flexible member, still can eliminate self damage of stress to lead-in wire when vibrations are comparatively violent.Adopt Positive-Negative Action spring design, both guaranteed that element had shock-resistance features, avoid again because of spring-force driven dual, cause the fixing difficult phenomenon of element to occur.Temperature element of the present utility model has applied range, and fixed form is flexible, long service life, and the features such as easy access, are conducive to reduce maintenance cost.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
