Abstract
The utility model discloses a performance tuning position indicating device of a refrigeration screw compressor. The technical scheme adopted by utility model is that the performance tuning position indicating device of the refrigeration screw compressor disclosed by the utility model comprises a screw compressor cylinder body (1) and a screw compressor cylinder body end cover (2). The performance tuning position indicating device is characterized in that a loading position delivering rod (10) is mounted in the centre (21) of the screw compressor cylinder body end cover (2); and the loading position delivering rod (10) is connected in sequence with a rotary magnetic encoder (4) and a performance tuning position indicating rotary plate (5) and fixed by a locking bolt (8). In addition, an outer ring (22) of the screw compressor cylinder body end cover (2) is connected in sequence with a performance tuning position indicating protective shield (3), a performance tuning position indicating protective shield covering plate (6) and a performance tuning position indicating display window (7) and fixed by a covering plate bolt (9). Compared with the original potentiometer original and the limit switch, the performance tuning position indicating device of the refrigeration screw compressor has the advantages that the impact resistance, the shock resistance, the reliability, the moisture protection, the interference resistance and other aspects are significantly improved and the service life of the compressor is prolonged.
Description
Technical field
The present invention relates to F25B refrigerator on International Classification of Patents (IPC) through retrieval, and chiller plant or system's classification especially belong to refrigeration screw compression function adjusted position indicating device.
Background technique
Existing screw compression function is transferred and is carried the position indicating device, all adopt potentiometer and limit switch, when the increase and decrease of compressor energy was carried, sliding piston moved in oil cylinder, kinetic energy transfers a year position transmission bar to rotate, and can transfer and carry position transmission bar drive potentiometer and a limit switch action.The transferring of the type carried a position indicating device, and usually to run into limit switch malfunctioning location when compressor operating inaccurate, potentiometer bad connection and cause the situation of compressor cisco unity malfunction.
Summary of the invention
The object of the present invention is to provide a kind of refrigeration screw compression function adjusted position indicating device, effectively overcome problem malfunctioning because of limit switch or the inaccurate compressor operating fault that causes in potentiometer location to reach, reach pinpoint purpose.
The technical solution used in the present invention is: it comprises helical-lobe compressor cylinder body (1) and helical-lobe compressor cylinder end caps (2), it is characterized in that: the central authorities (21) of described helical-lobe compressor cylinder end caps (2) are equipped with and carry position, position transmission bar (10), carry position position transmission bar (10) and be connected with magnetic rotary encoder (4), energy adjusted position rotary disc for indication (5) successively, and fixing by lock bolt (8); In addition, the outer ring (22) of described helical-lobe compressor cylinder end caps (2) is connected with energy adjusted position indication safety cover (3), energy adjusted position indication safety cover cover plate (6) and the adjusted position indicated number window (7) of successively, and fixing by cover plate bolt (9).
Beneficial effect of the present invention is: 1, the present invention owing to utilizing magnetic rotary encoder to replace original potentiometer and limit switch, can overcome problem malfunctioning because of limit switch or the inaccurate compressor operating fault that causes in potentiometer location effectively; 2, the present invention transfers owing to utilizing magnetic rotary encoder to control the compression function, and the pulse output when utilizing the encoder rotation realizes that automatic control compressor can transfer; 3, the present invention and former potentiometer and limit switch are controlled and to be compared, shock-resistant, and antidetonation, reliability, the aspect such as moistureproof anti-interference all is significantly increased, and has extended compressor working life.
