Abstract
The utility model discloses a centrifugal compressor surge indicator which comprises a steel sheet connector (1) and a proximity switch (2). A rubber pad (3) and a sensor connector (4) are sequentially arranged in the steel sheet connector (1), the proximity switch (2) sequentially penetrates into the sensor connector (4) and the rubber pad (3) and is locked with the sensor connector (4) through a nut (5), a step (6) is arranged in the steel sheet connector (1), a boss (7) is arranged on the inner wall of the steel sheet connector (1), the rubber pad (3) is clamped at the boss (7), and a steel sheet (8) is arranged on the step (6) and corresponds to one end of the proximity switch (2). The centrifugal compressor surge indicator has the advantages of ingenious structural design and convenience in manufacture and installation, and can be used for timely giving an alarm and interrupting work of a motor when a centrifugal compressor has surge, so that damage of the compressor is prevented.
Description
Technical field
The utility model relates to a kind of centrifugal compressor indicator, particularly a kind of surge in centrifugal compressors indicator.
Background technique
Centrifugal compressor is widely used in the industries such as oil, chemical industry, metallurgy, and its safe and reliable operation has very important meaning to industrial production.Yet centrifugal compressor is responsive to pressure, flow, the temperature variation of gas, and surge easily occurs.Surge is the intrinsic a kind of phenomenon of centrifugal compressor, the reason that surge produces is when the centrifugal compressor flow is reduced to minimum value, outlet pressure can descend suddenly, manifold pressure is higher than outlet pressure on the contrary, so gas backflow returns in the machine, until raising, outlet pressure again carries gas to pipeline; When ducted pressure returned to original pressure, flow reduced again, and air in pipeline produces again refluence, a kind of unsettled operating mode of so going round and beginning again and producing, and surge has larger harmfulness, is one of main inducing of compressor damage.
The model utility content
The purpose of this utility model just provides and a kind ofly can reach alarm and the out-of-work surge in centrifugal compressors indicator of drive motor.
The purpose of this utility model is to realize by such technological scheme, a kind of surge in centrifugal compressors indicator, described indicator comprises steel disc joint and approach switch, in described steel disc joint, be disposed with rubber pad and sensor connector, described approach switch penetrates sensor connector and rubber pad and successively by nut and sensor connector locking, in the steel disc joint, be provided with step, inwall at the steel disc joint is provided with boss, described rubber pad is stuck in the boss place, be provided with steel disc at described step, described steel disc is corresponding with an end of approach switch.
Owing to having adopted technique scheme, the utlity model has structural design ingenious, make easily advantage be installed, adopt it when centrifugal compressor generation surge, to report to the police timely, and the interruption motor operation, prevented the damage of compressor.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of surge in centrifugal compressors indicator, described indicator comprises steel disc joint 1 and approach switch 2, in described steel disc joint 1, be disposed with rubber pad 3 and sensor connector 4, described approach switch 2 penetrates successively sensor connector 4 and rubber pad 3 and passes through nut 5 and sensor connector 4 lockings, in steel disc joint 1, be provided with step 6, inwall at steel disc joint 1 is provided with boss 7, described rubber pad 3 is stuck in boss 7 places, be provided with steel disc 8 at described step 6, described steel disc 8 is corresponding with an end of approach switch 2.
The surge indicator is vertically mounted on the entry end of compressor, under normal operation, wherein steel disc 8 because the vacuum action of ingress forces it downwards away from approach switch 2; When surge occurs, because the pressure opposite direction, so that steel disc 8 wherein moves upward, near approach switch 2, when distance approach switch 2 reaches critical value, namely send alarm signal, simultaneously, drive motor quits work, thereby avoids surge to cause further harm.
Claims (1)
1. surge in centrifugal compressors indicator, it is characterized in that: described indicator comprises steel disc joint (1) and approach switch (2), in described steel disc joint (1), be disposed with rubber pad (3) and sensor connector (4), described approach switch (2) penetrates successively sensor connector (4) and rubber pad (3) and passes through nut (5) and sensor connector (4) locking, in steel disc joint (1), be provided with step (6), inwall at steel disc joint (1) is provided with boss (7), described rubber pad (3) is stuck in boss (7) and locates, be provided with steel disc (8) at described step (6), described steel disc (8) is corresponding with an end of approach switch (2).
